Boys with obesity have lower testicular volume, compared with their normal-weight counterparts, suggesting the potential for fertility problems in adulthood, new data suggest.

Testicular volume is a fertility marker directly related to sperm count that has halved in the past 40 years worldwide for unknown reasons. At the same time, childhood obesity has risen dramatically and infertility appears to have risen as well, Rossella Cannarella, MD, of the department of endocrinology and andrology, University of Catania (Italy), said at the annual meeting of the Endocrine Society.

According to recent Italian studies, between 14% and 23% of young men aged 18-19 had testicular hypotrophy. “Worryingly, we don’t know the reason for this hypotrophy. And therefore, they are at risk for future infertility,” Dr. Cannarella said during a press briefing.

Her study, which included a total of 264 male children and adolescents, also linked lower testicular volume to hyperinsulinemia and insulin resistance. “The testis is not quiescent in childhood and is sensitive to the hormone insulin. Obesity and metabolic impairment actually can have an effect and negative impact on Sertoli cell proliferation,” Dr. Cannarella said.
 

Screen testicular volume at all visits

If other studies confirm these results, she said that pediatricians should begin routinely assessing testicular volume at all visits as is now done with height and weight to identify early deflection of the testicular growth curve.

In addition, “include male infertility as a possible consequence of obesity in counseling of male obese children,” she advised.

Asked to comment, Amin Sedaghat Herati, MD, director of male infertility and men’s health at Johns Hopkins Hospital, and assistant professor of urology at Johns Hopkins Medicine, both in Baltimore, said in an interview: “I think what’s really interesting about this study is the association that they’ve made between testicular volume and obesity.”

But, he noted, “it does not implicate necessarily the development of infertility. It’s an extrapolation. So it’s a step towards the link between obesity and infertility, and it’s an important study to establish the association, but changes in testicular volume and even changes in semen panel don’t necessarily indicate fertility or infertility.”

The findings are “consistent with what we know as far as what obesity can potentially do to the activity of the cells in the testes. The authors are postulating that it’s more the support cells, called Sertoli cells, but I would say it’s probably all of the cells that are being affected by obesity and specifically elevated leptin levels,” Dr. Herati said.

He agrees with the recommendation that pediatricians screen all boys for testicular volume. “I agree it’s a good idea so they don’t miss any cases in which the testes don’t develop the way they should or any other conditions,” Dr. Herati said. “I think in general it’s a good practice, especially in the peripubertal stage, to make sure that kids are on the same growth curve and that they’re meeting their Tanner staging. [Pediatricians] should be looking at the size of the testes and tracking, maybe not at every visit, but at least on an annual basis.”

And, he noted, “I think any study that establishes a link that we can point to when we’re educating patients and parents is important.”
 

Links found between overweight/obesity, testicular hypotrophy

The study population included 61 male children and adolescents with normal weight, 53 with overweight, and 150 with obesity. Insulin resistance (Homeostatic Model Assessment for Insulin Resistance index ≥ 2.5) was present in 97 participants, 22 had prediabetes, and 3 had type 2 diabetes. Clinical data were collected retrospectively.

Among the boys aged 9-14 years, those with overweight and obesity had significantly lower testicular volume, compared with those of normal weight.

Those who were in Tanner Stage 1 were more likely to have overweight and obesity than those with normal weight, suggesting that “overweight and obese adolescents start puberty later than those of normal weight,” Dr. Cannarella said.

In the 14- to 16-year-old age group, those with insulin resistance had lower testicular volume, compared with those without insulin resistance (HOMA index < 2.5). The number of insulin-resistant adolescents was greater than that of controls in the Tanner stage 2 group.

In both the prepubertal (< 9 years) and pubertal (14-16 years) groups, hyperinsulinemia was associated with lower levels of testicular volume.

Hyperinsulinemia did not influence the timing of puberty onset.
 

No way to quantify the effect of obesity on fertility just yet

During a press briefing, Dr. Cannarella commented that obesity is likely just one of several factors influencing what appears to be an increase in male infertility over time. “It isn’t of course the only reason, but many factors in our environment have drastically changed, compared to 40 years ago, including the prevalence of heavy metals and endocrine disruptors, and of course, the change in habits and higher prevalence of metabolic disease. All of this has an impact on the proliferation of Sertoli cells in childhood and this may explain the trend toward the decline of sperm concentration and count.”

Longitudinal data are needed to establish cause and effect, she noted. “We need longitudinal studies that link the degrees of testicular volume with the degree of the sperm concentration and count starting from childhood and ending with the adult age. This is the missing link so far.”

Dr. Cannarella has reported no relevant financial relationships. Dr. Herati has reported being an advisor for Dadi, LiNA Medical, and Teleflex.

Physicians have screened new and expectant mothers for perinatal depression for years. But what about fathers?

A new systematic review and meta-analysis suggests it’s time for health care providers to ask both parents about any mental health symptoms before and after their baby is born.

“We are screening most mothers for signs of perinatal depression,” said Kara Smythe, MD, at the department of primary care and population health and Institute of Epidemiology and Health Care at the University College London, who is the lead author of the study. “But we aren’t always asking about the relationship between them and the person helping them care for this newborn. If we don’t consider the experience of new fathers, we’re doing a disservice to everyone.”

Without screening both parents, health care providers can miss important clues to why child and parents experience adverse health outcomes post birth.

The study, published in JAMA Network Open, found that for 3.18% of couples, both parents concurrently experienced depression before and following a birth. The mental illness was more common in the late postnatal period (3-12 months).

According to the Centers for Disease Control and Prevention, about 1 in 8 women experience symptoms of postpartum depression. Other sources indicate the incidence may be much higher. Findings from a mobile app using the Edinburgh Postnatal Depression Scale presented at the American Psychiatric Association’s annual meeting in 2019 indicated more than half of the 164,237 women who used the free app reported symptoms of depression for up to a year following the birth of their baby.
 

The findings

Dr. Smythe and her team reviewed previously published observational studies on the prevalence of perinatal depression or anxiety in couples from the Ovid and Web of Science between Jan. 1, 1990, and June 8, 2021.

They ultimately included 23 studies with data from 29,286 couples. They broke the data into subgroups of persons with antenatal depression, early postnatal depression (0-12 weeks), late postnatal depression (3-13 months), and perinatal anxiety.

About 1.7% (P < .001) of couples experienced antenatal depression, and about 2.4% (P < .001) experienced early postnatal depression. About 3.2% (P < .001) experienced late postnatal depression. The data on perinatal anxiety were insufficient, they write.

The vast majority of couples included in the samples were White, heterosexual, and highly educated with a middle to high socioeconomic background. The pregnancies were reportedly wanted, if not planned. The majority of the studies – 21 – included in the analysis were from countries other than the United States.

According to the study, evidence suggests that paternal depression can lead to increased symptoms of depression in mothers during pregnancy and the following 6 months. Men reported perinatal depression at similar rates as women, and Dr. Smythe said it’s becoming clear that men experience similar struggles as they transition into fatherhood.

J. J. Parker, MD, a pediatric and internal attending physician at Lurie Children’s Hospital of Chicago and Northwestern Medicine, said the findings solidify what he has observed from his own experience as a new father and resident.

“You’re at higher risk of having depression if your partner has depression, but it’s important to see that in the numbers,” Dr. Parker told this news organization. “I think from a clinician standpoint, this demonstrates that 3% of infants are living in households where both parents are depressed, and that has major implications for the development and health of those children.”

Dr. Smythe and her colleagues found that if even one parent is experiencing a mood disorder such as depression or anxiety, the newborn can experience impaired bonding, behavioral problems, and other harms later in life.

If both parents are experiencing perinatal depression, those negative outcomes could be amplified, although Dr. Smythe said more research is needed to solidify the link.

“I think one quick takeaway for pediatricians, clinicians, and any other health care providers taking care of mothers and infants is to ask about the nonbirthing parent,” Dr. Parker said. “All clinicians can do that right away, even if the mother does not have depression.”

The study was independently supported. Dr. Smythe and her colleagues report no relevant financial relationships.

Similar to a phenomenon already well documented in women, inadequate nutrition appears to be linked to hormonal abnormalities and potentially preventable tibial cortical bone density loss in athletic men, according to results of a small, prospective study.

Based on these findings, “we suspect that a subset of male runners might not be fueling their bodies with enough nutrition and calories for their physical activity,” reported Melanie S. Haines, MD, at the annual meeting of the Endocrine Society.

This is not the first study to suggest male athletes are at risk of a condition equivalent to what has been commonly referred to as the female athlete triad, but it enlarges the objective data that the phenomenon is real, and it makes insufficient availability of energy the likely cause.

In women, the triad is described as a lack of adequate stored energy, irregular menses, and bone density loss. In men, menstrual cycles are not relevant, of course, but this study like others suggests a link between the failure to maintain adequate stores of energy, disturbances in hormone function, and decreased bone density in both men and women, Dr. Haines explained.
 

RED-S vs. male or female athlete triad

“There is now a move away from the term female athlete triad or male athlete triad,” Dr. Haines reported. Rather the factors of failing to maintain adequate energy for metabolic demands, hormonal disturbances, and bone density loss appear to be relevant to both sexes, according to Dr. Haines, an endocrinologist at Massachusetts General Hospital and assistant professor of medicine at Harvard Medical School, both in Boston. She said several groups, including the International Olympic Committee (IOC), have transitioned to the term RED-S to apply to both sexes.

“RED-S is an acronym for relative energy deficiency in sport, and it appears to be gaining traction,” Dr. Haines said in an interview.

According to her study and others, excessive lean body mass from failure to supply sufficient energy for physiological needs “negatively affects hormones and bone,” Dr. Haines explained. In men and women, endocrine disturbances are triggered when insufficient calories lead to inadequate macro- and micronutrients.

In this study, 31 men aged 16-30 years were evaluated. Fifteen were in the athlete group, defined by running at least 30 miles per week for at least the previous 6 months. There were 16 control subjects; all exercised less than 2 hours per week and did not participate in team sports, but they were not permitted in the study if their body mass index exceeded 27.5 kg/m².
 

Athletes vs. otherwise healthy controls

Conditions that affect bone health were exclusion criteria in both groups, and neither group was permitted to take medications affecting bone health other than dietary calcium or vitamin D supplements for 2 months prior to the study.

Tibial cortical porosity was significantly greater – signaling deterioration in microarchitecture – in athletes, compared with control subjects (P = .003), according to quantitative computed tomography measurements. There was also significantly lower tibial cortical bone mineral density (P = .008) among athletes relative to controls.

Conversely, tibial trabecular measures of bone density and architecture were better among athletes than controls, but this was expected and did not contradict the hypothesis of the study.

“Trabecular bone refers to the inner part of the bone, which increases with weight-bearing exercise, but cortical bone is the outer shell, and the source of stress fractures,” Dr. Haines explained.

The median age of both the athletes and the controls was 24 years. Baseline measurements were similar. Body mass index, fat mass, estradiol, and leptin were all numerically lower in the athletes than controls, but none were significant, although there was a trend for the difference in leptin (P = .085).
 

Hormones correlated with tibial failure load

When these characteristics were evaluated in the context of mean tibial failure load, a metric related to strength, there was a strongly significant positive association with lean body mass (R = 0.85; P < 0.001) and estradiol level (R = 0.66; P = .007). The relationship with leptin also reached significance (R = 0.59; P = .046).

Unexpectedly, there was no relationship between testosterone and tibial failure load. The reason is unclear, but Dr. Haines’s interpretation is that the relationship between specific hormonal disturbances and bone density loss “might not be as simple” as once hypothesized.

The next step is a longitudinal evaluation of the same group of athletes to follow changes in the relationship between these variables over time, according to Dr. Haines.

Eventually, with evidence that there is a causal relationship between nutrition, hormonal changes, and bone loss, the research in this area will focus on better detection of risk and prophylactic strategies.

“Intervention trials to show that we can prevent stress factors will be difficult to perform,” Dr. Haines acknowledged, but she said that preventing adverse changes in bone at relatively young ages could have implications for long-term bone health, including protection from osteoporosis later in life.

The research presented by Dr. Haines is consistent with an area of research that is several decades old, at least in females, according to Siobhan M. Statuta, MD, a sports medicine primary care specialist at the University of Virginia, Charlottesville. The evidence that the same phenomenon occurs in men is more recent, but she said that it is now well accepted the there is a parallel hormonal issue in men and women.

“It is not a question of not eating enough. Often, athletes continue to consume the same diet, but their activity increases,” Dr. Statuta explained. “The problem is that they are not supplying enough of the calories they need to sustain the energy they are expending. You might say they are not fueling their engines appropriately.”

In 2014, the International Olympic Committee published a consensus statement on RED-S. They described this as a condition in which a state of energy deficiency leads to numerous complications in athletes, not just osteoporosis. Rather, a host of physiological systems, ranging from gastrointestinal complaints to cardiovascular events, were described.
 

RED-S addresses health beyond bones

“The RED-S theory is better described as a spoke-and-wheel concept rather than a triad. While inadequate energy availability is important to both, RED-S places this at the center of the wheel with spokes leading to all the possible complications rather than as a first event in a limited triad,” Dr. Statuta said in an interview.

However, she noted that the term RED-S is not yet appropriate to replace that of the male and female athlete triad.

“More research is required to hash out the relationship of a body in a state of energy deficiency and how it affects the entire body, which is the principle of RED-S,” Dr. Statuta said. “There likely are scientific effects, and we are currently investigating these relationships more.”

“These are really quite similar entities but have different foci,” she added. Based on data collected over several decades, “the triad narrows in on two body systems affected by low energy – the reproductive system and bones. RED-S incorporates these same systems yet adds on many more organ systems.

The original group of researchers have remained loyal to the concept of the triad that involves inadequate availability of energy followed by hormonal irregularities and osteoporosis. This group, the Female and Male Athlete Triad Coalition, has issued publications on this topic several times. Consensus statements were updated last year.

“The premise is that the triad leading to bone loss is shared by both men and women, even if the clinical manifestations differ,” said Dr. Statuta. The most notable difference is that men do not experience menstrual irregularities, but Dr. Statuta suggested that the clinical consequences are not necessarily any less.

“Males do not have menstrual cycles as an outward marker of an endocrine disturbance, so it is harder to recognize clinically, but I think there is agreement that not having enough energy available is the trigger of endocrine changes and then bone loss is relevant to both sexes,” she said. She said this is supported by a growing body of evidence, including the data presented by Dr. Haines at the Endocrine Society meeting.

Dr. Haines and Dr. Statuta report no potential conflicts of interest.

Similar to a phenomenon already well documented in women, inadequate nutrition appears to be linked to hormonal abnormalities and potentially preventable tibial cortical bone density loss in athletic men, according to results of a small, prospective study.

Based on these findings, “we suspect that a subset of male runners might not be fueling their bodies with enough nutrition and calories for their physical activity,” reported Melanie S. Haines, MD, at the annual meeting of the Endocrine Society.

This is not the first study to suggest male athletes are at risk of a condition equivalent to what has been commonly referred to as the female athlete triad, but it enlarges the objective data that the phenomenon is real, and it makes insufficient availability of energy the likely cause.

In women, the triad is described as a lack of adequate stored energy, irregular menses, and bone density loss. In men, menstrual cycles are not relevant, of course, but this study like others suggests a link between the failure to maintain adequate stores of energy, disturbances in hormone function, and decreased bone density in both men and women, Dr. Haines explained.
 

RED-S vs. male or female athlete triad

“There is now a move away from the term female athlete triad or male athlete triad,” Dr. Haines reported. Rather the factors of failing to maintain adequate energy for metabolic demands, hormonal disturbances, and bone density loss appear to be relevant to both sexes, according to Dr. Haines, an endocrinologist at Massachusetts General Hospital and assistant professor of medicine at Harvard Medical School, both in Boston. She said several groups, including the International Olympic Committee (IOC), have transitioned to the term RED-S to apply to both sexes.

“RED-S is an acronym for relative energy deficiency in sport, and it appears to be gaining traction,” Dr. Haines said in an interview.

According to her study and others, excessive lean body mass from failure to supply sufficient energy for physiological needs “negatively affects hormones and bone,” Dr. Haines explained. In men and women, endocrine disturbances are triggered when insufficient calories lead to inadequate macro- and micronutrients.

In this study, 31 men aged 16-30 years were evaluated. Fifteen were in the athlete group, defined by running at least 30 miles per week for at least the previous 6 months. There were 16 control subjects; all exercised less than 2 hours per week and did not participate in team sports, but they were not permitted in the study if their body mass index exceeded 27.5 kg/m².
 

Athletes vs. otherwise healthy controls

Conditions that affect bone health were exclusion criteria in both groups, and neither group was permitted to take medications affecting bone health other than dietary calcium or vitamin D supplements for 2 months prior to the study.

Tibial cortical porosity was significantly greater – signaling deterioration in microarchitecture – in athletes, compared with control subjects (P = .003), according to quantitative computed tomography measurements. There was also significantly lower tibial cortical bone mineral density (P = .008) among athletes relative to controls.

Conversely, tibial trabecular measures of bone density and architecture were better among athletes than controls, but this was expected and did not contradict the hypothesis of the study.

“Trabecular bone refers to the inner part of the bone, which increases with weight-bearing exercise, but cortical bone is the outer shell, and the source of stress fractures,” Dr. Haines explained.

The median age of both the athletes and the controls was 24 years. Baseline measurements were similar. Body mass index, fat mass, estradiol, and leptin were all numerically lower in the athletes than controls, but none were significant, although there was a trend for the difference in leptin (P = .085).
 

Hormones correlated with tibial failure load

When these characteristics were evaluated in the context of mean tibial failure load, a metric related to strength, there was a strongly significant positive association with lean body mass (R = 0.85; P < 0.001) and estradiol level (R = 0.66; P = .007). The relationship with leptin also reached significance (R = 0.59; P = .046).

Unexpectedly, there was no relationship between testosterone and tibial failure load. The reason is unclear, but Dr. Haines’s interpretation is that the relationship between specific hormonal disturbances and bone density loss “might not be as simple” as once hypothesized.

The next step is a longitudinal evaluation of the same group of athletes to follow changes in the relationship between these variables over time, according to Dr. Haines.

Eventually, with evidence that there is a causal relationship between nutrition, hormonal changes, and bone loss, the research in this area will focus on better detection of risk and prophylactic strategies.

“Intervention trials to show that we can prevent stress factors will be difficult to perform,” Dr. Haines acknowledged, but she said that preventing adverse changes in bone at relatively young ages could have implications for long-term bone health, including protection from osteoporosis later in life.

The research presented by Dr. Haines is consistent with an area of research that is several decades old, at least in females, according to Siobhan M. Statuta, MD, a sports medicine primary care specialist at the University of Virginia, Charlottesville. The evidence that the same phenomenon occurs in men is more recent, but she said that it is now well accepted the there is a parallel hormonal issue in men and women.

“It is not a question of not eating enough. Often, athletes continue to consume the same diet, but their activity increases,” Dr. Statuta explained. “The problem is that they are not supplying enough of the calories they need to sustain the energy they are expending. You might say they are not fueling their engines appropriately.”

In 2014, the International Olympic Committee published a consensus statement on RED-S. They described this as a condition in which a state of energy deficiency leads to numerous complications in athletes, not just osteoporosis. Rather, a host of physiological systems, ranging from gastrointestinal complaints to cardiovascular events, were described.
 

RED-S addresses health beyond bones

“The RED-S theory is better described as a spoke-and-wheel concept rather than a triad. While inadequate energy availability is important to both, RED-S places this at the center of the wheel with spokes leading to all the possible complications rather than as a first event in a limited triad,” Dr. Statuta said in an interview.

However, she noted that the term RED-S is not yet appropriate to replace that of the male and female athlete triad.

ATLANTA – Potential once-daily male oral contraceptives have passed a first clinical hurdle, showing a degree of testosterone suppression that should be sufficient for a contraceptive effect without causing symptomatic hypogonadism, according to phase 1 study results to be presented at the annual meeting of the Endocrine Society.

There are two pills in development and the studies so far suggest that both or a combination might be able to provide an acceptable balance of efficacy and tolerability, according to Tamar Jacobsohn, a researcher in the Contraceptive Development Program, Eunice Kennedy Shriver National Institute of Child Health and Human Development, Bethesda, Md.

The two drugs evaluated in this study are dimethandrolone undecanoate (DMAU) and 11b-methyl-19-nortestosterone-17b-dodecylcarbonate (11b-MNTDC). Both are bifunctional prodrugs with androgenic and progestogenic effects. The prodrugs are designed to be cleaved after ingestion so that the active hormones are released over 24 hours, permitting once-daily dosing.

“As potent androgens, these steroids suppress gonadotropin secretion, leading to markedly decreased serum testosterone production,” explained Ms. Jacobsohn in an interview.

However, she noted that there is still a long way to go on this research path. While the phase 1 studies have shown tolerability, the biology involved in suppressing sperm production suggests that men would need to take these pills daily for about 3 months at the very beginning of contraceptive treatment, until adequate sperm suppression is achieved to prevent pregnancy.

“We are working toward a phase 2 trial that will include a contraceptive efficacy endpoint, but there are lots of steps to get there, including more early phase studies,” she noted.

“There is a huge unmet need in terms of male contraceptive methods,” said Arthi Thirumalai, MBBS, an endocrinologist and assistant professor of medicine at the University of Washington School of Medicine in Seattle.

Senior author of a 2020 review article on male contraception, Dr. Thirumalai said in an interview that prodrugs and other hormonal methods to lower testosterone and suppress sperm production are attractive because of convenience, efficacy, and reversibility,

“We hope that oral formulations can be used to address this need,” said Dr. Thirumalai, who has participated in several experimental and clinical studies of male contraception methods. She is, in fact, one of the many coauthors of the data presented by Ms. Jacobsohn.

Ms. Jacobsohn emphasized: “Development of an effective, reversible male contraceptive method will improve reproductive options for men and women, have a major impact on public health by decreasing unintended pregnancy, and allow men to have an increasingly active role in family planning.”

Phase 1 results with DMAU and MNTDC

The work that led to phase 1 studies suggested that each of the drugs — DMAU and MNTDC — might provide adequate hormone suppression to reduce sperm counts without inducing unacceptable symptoms of hypogonadism. To test this potential, dose-ranging phase 1 studies with an endpoint of testosterone suppression were conducted with each one.

In the two placebo-controlled phase 1a studies, which are to be presented in a poster on June 13, healthy male subjects were randomly assigned to two pills of active therapy, four pills of active therapy, or placebo. In the two studies combined, 39 subjects received DMAU, 30 received 11b-MNTDC, and 28 received placebo.

Efficacy was evaluated by measuring testosterone levels. Tolerability was largely based on patient questionnaires.

At the end of 7 days, testosterone levels remained at reference levels (400 to 600 ng/dL) in those who received placebo. The levels fell to less than 100 ng/dL in all subjects assigned to an active agent regardless of which agent or dose was used.

From day 7 to 28, there was less median suppression of testosterone on 200 mg than 400 mg daily (92.7 ng/dL vs. 49.6 ng/dL; P < .001), but both remained below the target of 100 ng/dL, Ms. Jacobsohn reported.

The difference in degree of testosterone suppression did not appear to influence tolerability.

Subjects on four vs. two daily pills “did not report a significant difference in general satisfaction or their willingness to use the pills in the future or recommend them to other men,” said Ms. Jacobson, presenting P values for these outcomes among subjects on active therapy relative to placebo that were not significant, ranging from 0.48 to 0.85.

Overall, there were no serious adverse events. Mild side effects associated with hypogonadism did occur, but “all resolved by the end of the study,” she said.

Zero sperm production is not the goal. Lowering it sufficiently is

Dr. Thirumalai said the need for a male contraceptive is strong. While condoms have a substantial failure rate, vasectomy is not reliably reversible even though the majority of men agree that the responsibility for preventing pregnancy should be shared, she said.

Dr. Thirumalai’s earlier review article found that clinical trials of hormonal suppression to provide male contraception have been conducted for at least 30 years. The challenge has been finding an effective therapy that is well tolerated.

Drugs that combine both androgenic and progestogenic activity might be the answer. By manipulating hormones that lower testosterone, sperm production is reduced without eliminating a man’s ability to ejaculate. Zero sperm production is not the goal, according to data in Dr. Thirumalai’s review article.

Rather, studies suggest that when ejaculate contains less than 1 million sperm per mL (levels typically range from 15 to 200 million sperm/mL), the antipregnancy efficacy is similar to that achieved with female oral contraceptives.

However, clinical trials to demonstrate that this can be achieved safely have yet to be conducted.

Ms. Jacobsohn said that sperm half-life is about 3 months. This means that patients would need to be on hormonal therapy for a period of about this duration before reliable contraception is achieved.

In other words, the efficacy endpoint used in this current study [of 28 days duration] does not ensure effective contraception, but Ms. Jacobsohn suggested this is nevertheless an important step forward in clinical development.

Ms. Jacobsohn and Dr. Thirumalai report no relevant financial relationships.

Rather, studies suggest that when ejaculate contains less than 1 million sperm per mL (levels typically range from 15 to 200 million sperm/mL), the antipregnancy efficacy is similar to that achieved with female oral contraceptives.

However, clinical trials to demonstrate that this can be achieved safely have yet to be conducted.

Ms. Jacobsohn said that sperm half-life is about 3 months. This means that patients would need to be on hormonal therapy for a period of about this duration before reliable contraception is achieved.

In other words, the efficacy endpoint used in this current study [of 28 days duration] does not ensure effective contraception, but Ms. Jacobsohn suggested this is nevertheless an important step forward in clinical development.

Ms. Jacobsohn and Dr. Thirumalai report no relevant financial relationships.

Despite a new meta-analysis claiming to show that testosterone replacement therapy for men with hypogonadism does not increase the risk of cardiovascular outcomes such as myocardial infarction or stroke, experts say the jury is still out.

A more definitive answer for cardiovascular safety of testosterone therapy will come from the TRAVERSE dedicated cardiovascular outcome trial, sponsored by AbbVie, which will have up to 5 years of follow-up, with results expected later this year.

The current meta-analysis by Jemma Hudson of Aberdeen (Scotland) University and colleagues was published online in The Lancet Healthy Longevity. The work will also be presented June 13 at ENDO 2022, the Endocrine Society’s annual meeting in Atlanta, Georgia, by senior author Channa Y. Jayasena, MD, PhD.

In 2014, the U.S. Food and Drug Administration mandated a label on testosterone products warning of possible increased cardiovascular risks and to reserve the therapy for symptomatic hypogonadism only. In contrast, the European Medicines Agency concluded that when hypogonadism is properly diagnosed and managed, there is currently no clear, consistent evidence that testosterone therapy causes increased cardiovascular risk.

To address this uncertainty, Dr. Hudson and colleagues formed a global collaborative to obtain individual patient data on cardiovascular outcomes from randomized controlled trials of testosterone therapy for men with hypogonadism.

They pooled data from 35 trials published from 1992 to Aug. 27, 2018, including 17 trials (3,431 patients) for which the researchers obtained patient-level data. The individual trials were 3-12 months long, except for one 3-year trial.

During a mean follow-up of 9.5 months, there was no significant increase in cardiovascular outcomes in men randomized to testosterone therapy versus placebo (odds ratio, 1.07; P = .62), nor were there any significantly increased risks of death, stroke, or different types of cardiovascular outcome, although those numbers were small.  

This is “the most comprehensive study to date investigating the safety of testosterone treatment of hypogonadism,” according to the researchers. “The current results provide some reassurance about the short-term to medium-term safety of testosterone to treat male hypogonadism,” they conclude.

However, they also acknowledge that “long-term data are needed to fully evaluate the safety of testosterone.”

Erin D. Michos, MD, coauthor of an accompanying editorial, told this news organization, “This study doesn’t say to me that low testosterone necessarily needs to be treated. It’s still not indicated in people just for a low number [for blood testosterone] with less-severe symptoms. It really comes down to each individual person, how symptomatic they are, and their cardiovascular risk.”

‘Trial is not definitive’

Dr. Michos is not the only person to be skeptical. Together with Steven Nissen, MD, an investigator for the TRAVERSE trial, she agrees that this new evidence is not yet decisive, largely because the individual trials in the meta-analysis were short and not designed as cardiovascular outcome trials.

Dr. Nissen, a cardiologist at Cleveland Clinic, added that the individual trials were heterogeneous, with “very few real cardiovascular events,” so the meta-analysis “is not definitive,” he said in an interview.

While this meta-analysis “that pooled together a lot of smaller studies is reassuring that there’s no signal of harm, it’s really inconclusive because the follow-up was really short – a mean of only 9.5 months – and you really need a larger study with longer follow up to be more conclusive,” Dr. Michos noted.

“We should have more data soon” from TRAVERSE, said Dr. Michos, from the division of cardiology, Johns Hopkins University, Baltimore, who is not involved with that study.

Meanwhile, “I don’t think [this analysis] changes the current recommendations,” she said.

“We should continue to use caution as indicated by the FDA label and only use testosterone therapy selectively in people who have true symptoms of hypogonadism,” and be cautious about using it particularly in men at higher cardiovascular risk because of family history or known personal heart disease.

On the other hand, the meta-analysis did not show harm, she noted, “so we don’t necessarily need to pull patients off therapy if they are already taking it. But I wouldn’t right now just start new patients on it unless they had a strong indication.”

“Certainly, great caution is advised regarding the use of testosterone replacement therapy in people with established atherosclerosis due to the findings of plaque progression in the testosterone trials and the excess cardiovascular events observed in the TOM trial, write Dr. Michos and fellow editorialist Matthew J. Budoff, MD, of University of California, Los Angeles, in their editorial.
 

Earlier data inconclusive

Testosterone concentrations progressively decline in men with advancing age, at about 2% per year, Dr. Michos and Dr. Budoff write. In addition, men with obesity or with diabetes have low levels of testosterone, Dr. Michos noted.

Low testosterone blood levels have been associated with insulin resistance, inflammation, dyslipidemia, and atherosclerosis. Testosterone replacement therapy has been used to increase libido, improve erectile dysfunction, and boost energy levels, mood, and muscle strength.

But it is well known that testosterone increases hematocrit, which has the potential to increase the risk of venous thromboembolism.

Two large observational studies have reported increased risks of myocardial infarction, stroke, and death in men taking testosterone, compared with nonusers, but the study designs have been widely criticized, Dr. Hudson and coauthors say in their article.  

A placebo-controlled trial was stopped early by its data- and safety-monitoring board following increased cardiovascular events in men aged 65 and older who received 6 months of testosterone. Other controlled trials have not observed these effects, but none was sufficiently powered.
 

Meta-analysis results

Dr. Hudson and colleagues performed a meta-analysis of 35 trials in 5,601 men aged 18 years and older with low baseline testosterone (≤ 350 nmol/dL) who had been randomized to testosterone replacement therapy or placebo for at least 3 months, for which there were data on mortality, stroke, and cardiovascular outcomes.

The men were a mean age of 65, had a mean body mass index of 30 kg/m², and most (88%) were White. A quarter had angina, 8% had a previous myocardial infarction, and 27% had diabetes. 

Cardiovascular and cerebrovascular outcomes were not primary outcomes.

During a mean follow-up of 9.5 months, in the 13 trials that provided this information, the rate of cardiovascular events was similar in the men who received testosterone (120/1,601, 7.5%) compared with those who received placebo (110/1,519, 7.2%).

In the 14 trials that provided this information, fewer deaths were reported during testosterone treatment (6/1,621, 0.4%) than during placebo treatment (12/1,537, 0.8%), but these numbers were too small to establish whether testosterone reduced mortality risk.

The most common cardiovascular events were arrhythmia, followed by coronary heart disease, heart failure, and myocardial infarction.

Patient age, baseline testosterone, smoking status, or diabetes status were not associated with cardiovascular risk.

The only detected adverse effects were edema and a modest lowering of HDL cholesterol.

“Men who develop sexual dysfunction, unexplained anemia, or osteoporosis should be tested for low testosterone,” senior author of the meta-analysis Dr. Jayasena said in an email to this news organization.

However, Dr. Jayasena added, “Mass screening for testosterone has no benefit in asymptomatic men.”

“Older men may still benefit from testosterone, but only if they have the clinical features [of hypogonadism] and low testosterone levels,” he concluded.  

The current study is supported by the Health Technology Assessment program of the National Institute for Health Research. The TRAVERSE trial is sponsored by AbbVie. Dr. Jayasena has reported receiving research grants from LogixX Pharma. Dr. Hudson has reported no relevant financial relationships. Disclosures for the other authors are listed in the article. Dr. Michos has reported receiving support from the Amato Fund in Women’s Cardiovascular Health at Johns Hopkins School of Medicine and serving on medical advisory boards for Novartis, Esperion, Amarin, and AstraZeneca outside the submitted work. Dr. Budoff has reported receiving grant support from General Electric.

If you have bacteria in your urine but don’t have symptoms of a urinary tract infection (UTI), such as burning or frequent urination, you probably don’t need antibiotics. So why did you get that prescription?

The Infectious Diseases Society of America recommends against antibiotics in this scenario, with exceptions for patients who are pregnant or undergoing certain urologic procedures.

Antibiotics for asymptomatic bacteriuria (ASB) generally do not help; are costly; and can cause side effects, Clostridioides difficile infection, and antibiotic resistance.

Still, antibiotic treatment for asymptomatic bacteriuria remains common, despite guidelines.

And when researchers recently surveyed 551 primary care clinicians to see which ones would inappropriately prescribe antibiotics for a positive urine culture, the answer was most of them: 71%.

“Regardless of years in practice, training background, or professional degree, most clinicians indicated that they would prescribe antibiotics for asymptomatic bacteriuria,” the researchers reported in JAMA Network Open.

Some groups of clinicians seemed especially likely to prescribe antibiotics unnecessarily.

“Medical maximizers” – clinicians who prefer treatment even when its value is ambiguous – and family medicine clinicians were more likely to prescribe antibiotics in response to a hypothetical case.

What to do for Mr. Williams?

To examine clinician attitudes and characteristics associated with prescribing antibiotics for asymptomatic bacteriuria, Dr. Baghdadi and his colleagues analyzed survey responses from 490 physicians and 61 advanced practice clinicians.

Study participants completed tests that measure numeracy, risk-taking preferences, burnout, and tendency to maximize care. They were presented with four hypothetical clinical scenarios, including a case of asymptomatic bacteriuria: “Mr. Williams, a 65-year-old man, comes to the office for follow-up of his osteoarthritis. He has noted foul-smelling urine and no pain or difficulty with urination. A urine dipstick shows trace blood. He has no particular preference for testing and wants your advice.”

Clinicians who had been in practice for at least 10 years were more likely to prescribe antibiotics (82%) to “Mr. Williams” than were those with 3-9 years in practice (73%) or less than 3 years in practice (64%).

Breaking a habit

Some prescribers may know not to treat asymptomatic bacteriuria but mistakenly consider certain findings to be symptoms of UTI.

Bradley Langford, PharmD, an antimicrobial stewardship expert with Public Health Ontario, said in his experience, most clinicians who say they know not to treat ASB incorrectly believe that cloudy urine, altered cognition, and other nonspecific symptoms indicate a UTI.

“The fact that most clinicians would treat ASB suggests that there is still a lot of work to do to improve antimicrobial stewardship, particularly outside of the hospital setting,” Dr. Langford told this news organization.

Avoiding unnecessary antibiotics is important not just because of the lack of benefit, but also because of the potential harms, said Dr. Langford. He has created a list of rebuttals for commonly given reasons for testing and treating asymptomatic bacteriuria.

“Using antibiotics for ASB can counterintuitively increase the risk for symptomatic UTI due to the disruption of protective local microflora, allowing for the growth of more pathogenic/resistant organisms,” he said.

One approach to addressing the problem: Don’t test urine in the first place if patients are asymptomatic. Virtual learning sessions have been shown to reduce urine culturing and urinary antibiotic prescribing in long-term care homes, Dr. Langford noted.

Updated training for health care professionals from the outset may also be key, and the lower rate of prescribing intent among resident physicians is reassuring, he said.
 

A role for patients

Patients could also help decrease the inappropriate use of antibiotics.

“Be clear with your doctor about your expectations for the health care interaction, including whether you are expecting to receive antibiotics,” Dr. Baghdadi said. “Your doctor may assume you contacted them because you wanted a prescription. If you are not expecting antibiotics, you should feel free to say so. And if you are asymptomatic, you may not need antibiotics, even if the urine culture is positive.”

The study was funded by a grant from the National Institutes of Health, and Dr. Baghdadi received grant support from the University of Maryland, Baltimore Institute for Clinical and Translational Research. Coauthors disclosed government grants and ties to Memorial Sloan Kettering Cancer Center, Vedanta Biosciences, Opentrons, and Fimbrion. Dr. Langford reported no relevant financial conflicts of interest.

The Infectious Diseases Society of America recommends against antibiotics in this scenario, with exceptions for patients who are pregnant or undergoing certain urologic procedures.

Antibiotics for asymptomatic bacteriuria (ASB) generally do not help; are costly; and can cause side effects, Clostridioides difficile infection, and antibiotic resistance.

Still, antibiotic treatment for asymptomatic bacteriuria remains common, despite guidelines.

And when researchers recently surveyed 551 primary care clinicians to see which ones would inappropriately prescribe antibiotics for a positive urine culture, the answer was most of them: 71%.

“Regardless of years in practice, training background, or professional degree, most clinicians indicated that they would prescribe antibiotics for asymptomatic bacteriuria,” the researchers reported in JAMA Network Open.

Some groups of clinicians seemed especially likely to prescribe antibiotics unnecessarily.

“Medical maximizers” – clinicians who prefer treatment even when its value is ambiguous – and family medicine clinicians were more likely to prescribe antibiotics in response to a hypothetical case.

What to do for Mr. Williams?

To examine clinician attitudes and characteristics associated with prescribing antibiotics for asymptomatic bacteriuria, Dr. Baghdadi and his colleagues analyzed survey responses from 490 physicians and 61 advanced practice clinicians.

Study participants completed tests that measure numeracy, risk-taking preferences, burnout, and tendency to maximize care. They were presented with four hypothetical clinical scenarios, including a case of asymptomatic bacteriuria: “Mr. Williams, a 65-year-old man, comes to the office for follow-up of his osteoarthritis. He has noted foul-smelling urine and no pain or difficulty with urination. A urine dipstick shows trace blood. He has no particular preference for testing and wants your advice.”

Clinicians who had been in practice for at least 10 years were more likely to prescribe antibiotics (82%) to “Mr. Williams” than were those with 3-9 years in practice (73%) or less than 3 years in practice (64%).

Breaking a habit

Some prescribers may know not to treat asymptomatic bacteriuria but mistakenly consider certain findings to be symptoms of UTI.

Bradley Langford, PharmD, an antimicrobial stewardship expert with Public Health Ontario, said in his experience, most clinicians who say they know not to treat ASB incorrectly believe that cloudy urine, altered cognition, and other nonspecific symptoms indicate a UTI.

“The fact that most clinicians would treat ASB suggests that there is still a lot of work to do to improve antimicrobial stewardship, particularly outside of the hospital setting,” Dr. Langford told this news organization.

Avoiding unnecessary antibiotics is important not just because of the lack of benefit, but also because of the potential harms, said Dr. Langford. He has created a list of rebuttals for commonly given reasons for testing and treating asymptomatic bacteriuria.

“Using antibiotics for ASB can counterintuitively increase the risk for symptomatic UTI due to the disruption of protective local microflora, allowing for the growth of more pathogenic/resistant organisms,” he said.

One approach to addressing the problem: Don’t test urine in the first place if patients are asymptomatic. Virtual learning sessions have been shown to reduce urine culturing and urinary antibiotic prescribing in long-term care homes, Dr. Langford noted.

Updated training for health care professionals from the outset may also be key, and the lower rate of prescribing intent among resident physicians is reassuring, he said.
 

A role for patients

Patients could also help decrease the inappropriate use of antibiotics.

“Be clear with your doctor about your expectations for the health care interaction, including whether you are expecting to receive antibiotics,” Dr. Baghdadi said. “Your doctor may assume you contacted them because you wanted a prescription. If you are not expecting antibiotics, you should feel free to say so. And if you are asymptomatic, you may not need antibiotics, even if the urine culture is positive.”

The study was funded by a grant from the National Institutes of Health, and Dr. Baghdadi received grant support from the University of Maryland, Baltimore Institute for Clinical and Translational Research. Coauthors disclosed government grants and ties to Memorial Sloan Kettering Cancer Center, Vedanta Biosciences, Opentrons, and Fimbrion. Dr. Langford reported no relevant financial conflicts of interest.

A new study suggests that, at least for certain male patients, the answer to infertility might lie with epigenetics.

According to the study, a commercially available test of epigenetic anomalies – factors that affect how genes express themselves – can grade the likelihood that sperm are viable for conception.

“The uniqueness of epigenetics is that some of the abnormalities detected have the potential to be modified with lifestyle,” said Larry I. Lipshultz, MD, head of the Division of Male Reproductive Medicine and Surgery at Baylor College of Medicine, Houston, who presented the new findings at the 2022 annual meeting of the American Urological Association.

For decades, semen analysis has been based on motility, morphology, and concentration. But these measures, while useful, are limited. Semen can still have low capacity for producing a pregnancy even when all three parameters are normal, Dr. Lipshultz told this news organization.

The test, called Path SpermQT (Inherent Biosciences) detects unstable gene promotors, which are the epigenetic markers for gene expression. In previous work with more than 1,300 gene samples, expression of the specific genes regulated by these promoters were linked to a wide variety of functions relevant to fertilization, such as spermatogenesis.

The test does not attempt to look for expression of specific unstable promoters but rather quantifies them to characterize sperm quality as excellent (≤ 10 unstable promoters), average (11-42), or poor (≥ 43).

In the studies that led to development of the SpermQT test, the number of unstable promoters correlated with pregnancy success. Pregnancy was achieved even among those in the group with poor sperm quality – but at very low rates.

Of the 172 semen samples collected so far in the ongoing analysis, sperm quality was characterized as excellent in 31%, average in 59%, and poor in 10%.

The stratifications for sperm quality were not significantly correlated with common measures of sperm viability, such as concentration, Dr. Lipshultz reported.

Certain patient characteristics were associated with greater sperm quality. These included use of antioxidant supplementation and low estrogen levels, as seen in men who had taken aromatase inhibitors.

So far, only one natural conception has occurred in the group with poor sperm versus eight in those with average or excellent quality.

The prognostic role of the test is only part of the picture.

“The exciting thing about this area of research is that epigenetics can be changed,” Dr. Lipshultz said in an interview. Based on the data so far, he said he is already starting to consider antioxidant supplementation and hormone modifications when sperm quality is poor.

The value of the Path SpermQT test for identifying treatment targets might eventually revolutionize the management of male infertility, Dr. Lipshultz said, but it has more immediate potential in helping couples decide whether to proceed with in vitro fertilization (IVF).

“We often see patients at an impasse when they are trying to decide to move to IVF,” he said. “A test like this could provide some direction. If sperm quality is good, the advice might be to keep trying. If poor, then a couple might want to move to IVF more quickly.”

A test of sperm quality on the basis of epigenetics “could change how we look at couples attempting to conceive,” agreed Peter N. Schlegel, MD, professor of urology and reproductive medicine, Weill Cornell Medicine, New York.

Dr. Schlegel praised several characteristics of the epigenetics test, including that 70%-80% of men with poor quality with SpermQT have normal results on standard assessments of semen. This finding suggests the tool is providing unique information about patients. He also noted that the studies so far indicate that sperm of poor quality for natural conception is still viable for IVF fertilization – which could be useful for couples weighing their options.

However, while the test is already available, Dr. Schlegel cautioned that much of the promise has yet to be documented.

“The results to date, despite being statistically significant, have only been gleaned from a small group of patients,” he said. “Much larger studies are needed before a change in practice is warranted.”

The value of SpermQT for identifying modifiable risks might be even further away.

“It is well recognized that environmental and lifestyle changes can affect methylation, but it is not known if the abnormalities seen so far could be influenced by lifestyle changes,” Dr. Schlegel said. Among the numerous steps needed to answer this question, he suggested that it might first be important “to evaluate why such changes in methylation occur.”

Dr. Lipshultz has financial relationships with several pharmaceutical companies, including Inherent Biosciences, which is marketing the SpermQT test. Dr. Schlegel has financial relationships with Theralogix, Posterity Health, and Roman Health.

A wearable patch that delivers electrical stimulation to the perineum may postpone premature ejaculation, according to research presented at the annual meeting of the American Urological Association. The disposable device appears to work by helping men contract the muscles in the pelvic floor, allowing them to postpone climax.

Among 34 men with a lifelong history of premature ejaculation, average intravaginal ejaculatory latency time – the time from vaginal penetration to ejaculation – increased from about 67 seconds at baseline to 123 seconds when they used the device.

Another 17 participants received a sham treatment – stimulation they could feel but that did not activate muscles. In this group, time to ejaculation increased from 63 seconds to 81 seconds.

The longer duration with active treatment was statistically significant (P < .0001), whereas the increase in the control group was not (P = .1653), said Ege Can Serefoglu, MD, a researcher at Biruni University, Istanbul, and editor-in-chief of the International Journal of Impotence Research.

Dr. Serefoglu is a member of the scientific advisory board for Virility Medical, a company in Hod Hasharon, Israel, that is developing the stimulator. Marketed as vPatch, the device is expected to be available in 2023, Dr. Serefoglu said. It was cleared by the Food and Drug Administration in November and has CE-mark approval in Europe, according to the company.
 

Common problem, limited options

Research shows that 20%-30% of men are not happy with their time to ejaculation, Dr. Serefoglu said.

The International Society for Sexual Medicine defines premature ejaculation as ejaculation which always or almost always occurs within about 1 minute of penetration, the patient is unable to delay this occurrence, and the condition causes personal distress.

“Unfortunately, in spite of its high prevalence we do not really have any satisfying treatment options,” Dr. Serefoglu said.

Topical anesthetics may be used to decrease the sensitivity of the glans penis, and selective serotonin reuptake inhibitors may help delay ejaculation. But these options have limited efficacy and low adherence, he said.

Preclinical studies have shown that injection of botulinum toxin into the bulbospongiosus muscles is associated with a dose-dependent increase in ejaculation latency in rats.

Data on ClinicalTrials.gov show that this approach also may increase ejaculation latency in men, Dr. Serefoglu said. Although investigators found no safety concerns, drugmaker Allergan made a strategic business decision to stop developing this treatment approach, according to the registration entry for the study.

The idea for vPatch came from researchers wondering if instead of paralyzing the muscles with botulinum toxin, they used electrical stimulation to cause contraction of those muscles, Dr. Serefoglu said. A smaller proof-of-concept study demonstrated the feasibility and safety of this technique.

To further assess the safety and efficacy of a transcutaneous perineal electrical stimulator for the treatment of premature ejaculation, investigators conducted the randomized, double-blind, sham-controlled trial at Rambam Medical Centre, Haifa, Israel, and Villa Donatello Clinic, Florence, Italy.

The trial included males with premature ejaculation aged 18-60 years. Their female partners measured IELT using a stopwatch during four sexual intercourse sessions before treatment, and four times on treatment, at home.

In addition to the increased time to ejaculation, perceived control over ejaculation, satisfaction with sexual intercourse, personal distress related to ejaculation, and interpersonal difficulty related to ejaculation all significantly improved with vPatch, the researchers found.

Of participants who received active treatment, 73.5% reported a subjective sense of improvement versus 41.2% of the control group.
 

Potential reactions

No serious adverse events were observed, Dr. Serefoglu reported. Potential adverse reactions include redness, discomfort, and localized pain, according to the company’s website.

Men should not use vPatch if they have been diagnosed with pelvic cancer, or if they have an implanted electronic device, diabetes with peripheral neuropathy, or perineal dermatologic diseases, irritations, or lesions. Other precautions include avoiding use of the vPatch in water or humid environments. The device has not been tested on use with a pregnant partner.

The disposable patches are meant for one-time use. “The miniaturized perineal stimulation device may become an on-demand, drug-free therapeutic option,” Dr. Serefoglu said.

Combining electrical stimulation with other treatment approaches may provide additional benefit, said Bradley Schwartz, DO, professor and chairman of urology at Southern Illinois University, Springfield, who moderated the session at the AUA meeting at which the results of the study were presented.

“You go from 1 to 2 minutes just with this device,” Dr. Schwartz said. “If you went from 2 to 3 minutes, you would essentially be tripling their pleasure or their time, which might make a significant difference.”

Serefoglu agreed that combining the stimulator with other treatment approaches such as topical anesthetics could increase patient satisfaction.

Comoderator Kelly Healy, MD, assistant professor of urology at Columbia University Medical Center, New York, highlighted a direction for future research: examining outcomes according to different types of relationships, as well as partner satisfaction.

“That is a perfect question that should also be considered in the future trials,” Dr. Serefoglu said. “This was mainly focused on the man’s satisfaction. But men are trying to delay their ejaculation to satisfy their partner.”

Dr. Serefoglu is on the scientific advisory board for Virility Medical, which sponsored the study. Dr. Healy had no disclosures. Dr. Schwartz disclosed ties to Cook Medical.

Study Overview

Objective: To evaluate whether the addition of the potent androgen-receptor inhibitor (ARA) darolutamide to the standard doublet androgen-deprivation therapy (ADT) and docetaxel in metastatic, hormone-sensitive prostate cancer (mHSPC) would increase survival.

Design: A randomized, double-blind, placebo-controlled, multicenter, phase 3 study. The results reported in this publication are from the prespecified interim analysis.

Intervention: Patients with mHSPC were randomly assigned to receive either darolutamide 600 mg twice daily or placebo. All patients received standard ADT with 6 cycles of docetaxel 75 mg/m² on day 1 every 21 days along with prednisone given within 6 weeks after randomization. Patients receiving luteinizing hormone–releasing hormone (LHRH) agonists as ADT were bridged with at least 4 weeks of first-generation antiandrogen therapy, which was discontinued before randomization. Treatments were continued until symptomatic disease progression, a change in neoplastic therapy, unacceptable toxicity, patient or physician decision, death, or nonadherence.

Setting and participants: Eligible patients included those newly diagnosed with mHSPC with metastases detected on contrast-enhanced computed tomography (CT) or magnetic resonance imaging (MRI) and bone scan. Patients were excluded if they had regional lymph node–only involvement or if they had received more than 12 weeks of ADT before randomization. Between November 2016 and June 2018, 1306 patients (651 in the darolutamide group and 655 in the placebo group) were randomized in a 1:1 manner to receive darolutamide 600 mg twice daily or placebo in addition to ADT and docetaxel. Randomization was stratified based on the TNM staging system (M1a—nonregional lymph node–only metastasis, M1b—bone metastasis with or without lymph node, or M1c—bone metastases) as well as baseline alkaline phosphatase levels.

Main outcome measures: The primary end point for the study was overall survival. Other meaningful secondary end points included time to castration resistance, time to pain progression, time to first symptomatic skeletal event, symptomatic skeletal event-free survival, time to subsequent systemic antineoplastic therapy, time to worsening of disease-related physical symptoms, initiation of opioid therapy for ≥7 days, and safety.

Results: The baseline and demographic characteristics were well balanced between the 2 groups. Median age was 67 years. Nearly 80% of patients had bone metastasis, and approximately 17% had visceral metastasis. At the data cutoff date for the primary analysis, the median duration of therapy was 41 months for darolutamide compared with 16.7 months in the placebo group; 45.9% in the darolutamide group and 19.1% in the placebo group were receiving the allotted trial therapy at the time of the analysis. Six cycles of docetaxel were completed in approximately 85% of patients in both arms. Median overall survival follow-up was 43.7 months (darolutamide) and 42.4 months (placebo). A significant improvement in overall survival was observed in the darolutamide group. The risk of death was 32.5% lower in the darolutamide cohort than in the placebo cohort (hazard ratio [HR], 0.68; 95% CI, 0.57-0.80; P < .001). The overall survival at 4 years was 62.7% (95% CI, 58.7-66.7) in the darolutamide arm and 50.4% (95% CI, 46.3-54.6) in the placebo arm. The overall survival results remained favorable across most subgroups.

Darolutamide was associated with improvement in all key secondary endpoints. Time to castration-resistance was significantly longer in the darolutamide group (HR, 0.36; 95% CI, 0.30-0.42; P < .001). Time to pain progression was also significantly longer in the darolutamide group (HR, 0.79; 95% CI, 0.66-0.95; P = .01). Time to first symptomatic skeletal events (HR, 0.71; 95% CI, 0.54-0.94; P = .02) and time to initiation of subsequent systemic therapy (HR, 0.39; 95% CI, 0.33-0.46; P < .001) were also found to be longer in the darolutamide group.

Safety: The risk of grade 3 or higher adverse events was similar across the 2 groups. Most common adverse events were known toxic effects of docetaxel therapy and were highest during the initial period when both groups received this therapy. These side effects progressively decreased after the initial period. The most common grade 3 or 4 adverse event was neutropenia, and its frequency was similar between the darolutamide and placebo groups (33.7% and 34.2%, respectively). The most frequently reported adverse events were alopecia, neutropenia, fatigue, and anemia and were similar between the groups. Adverse events of special significance, including fatigue, falls, fractures, and cardiovascular events, were also similar between the 2 groups. Adverse events causing deaths in each arm were low and similar (4.1% in the darolutamide group and 4.0% in the placebo group). The rates of discontinuation of darolutamide or placebo were similar (13.5% and 10.6%, respectively).

Conclusion: Among patients with mHSPC, overall survival was significantly longer among patients who received darolutamide plus ADT and docetaxel than among those who received ADT and docetaxel alone. This was observed despite a high percentage of patients in the placebo group receiving subsequent systemic therapy at the time of progression. The survival benefit of darolutamide was maintained across most subgroups. An improvement was also observed in the darolutamide arm in terms of key secondary end points. The adverse events were similar across the groups and were consistent with known safety profiles of ADT and docetaxel, and no new safety signals were identified in this trial.

Commentary

The results of the current study add to the body of literature supporting multi-agent systemic therapy in newly diagnosed mHSPC. Prior phase 3 trials of combination therapy using androgen-receptor pathway inhibitors, ADT, and docetaxel have shown conflicting results. The results from the previously reported PEACE-1 study showed improved overall survival among patients who received abiraterone with ADT and docetaxel as compared with those who received ADT and docetaxel alone.¹ However, as noted by the authors, the subgroup of patients in the ENZAMET trial who received docetaxel, enzalutamide, and ADT did not appear to have a survival advantage compared with those who received ADT and docetaxel alone.² The results from the current ARASENS trial provide compelling evidence in a population of prospectively randomized patients that combination therapy with darolutamide, docetaxel, and ADT improves overall survival in men with mHSPC. The survival advantage was maintained across subgroups analyzed in this study. Improvements were observed in regards to several key secondary end points with use of darolutamide. This benefit was maintained despite many patients receiving subsequent therapy at the time of progression. Importantly, there did not appear to be a significant increase in toxicity with triplet therapy. However, it is important to note that this cohort of patients appeared largely asymptomatic at the time of enrollment, with 70% of patients having an Eastern Cooperative Oncology Group performance status of 0.

Additionally, the average age in this study was 67 years, with only about 15% of the population being older than 75 years. In the reported subgroup analysis, those older than 75 years appeared to derive a similar benefit in overall survival, however. Whether triplet therapy should be universally adopted in all patients remains unclear. For example, there is a subset of patients with mHSPC with favorable- risk disease (ie, those with recurrent metastatic disease, node-only disease). In this population, the risk-benefit analysis is less clear, and whether these patients should receive this combination is not certain. Nevertheless, the results of this well-designed study are compelling and certainly represent a potential new standard treatment option for men with mHSPC. One of the strengths of this study was its large sample size that allowed for vigorous statistical analysis to evaluate the efficacy of darolutamide in combination with ADT and docetaxel.

Application for Clinical Practice

The ARASENS study provides convincing evidence that in men with mHSPC, the addition of darolutamide to docetaxel and ADT improves overall survival. This combination appeared to be well tolerated, with no evidence of increased toxicity noted. Certainly, this combination represents a potential new standard treatment option in this population; however, further understanding of which subgroups of men benefit from enhanced therapy is needed to aid in proper patient selection.

Takotsubo syndrome occurs much more frequently in women than it does in men, but men are much more likely to die from it, according to the results of a new study.

In an analysis of almost 2,500 patients with Takotsubo syndrome (TSS) who were enrolled in an international registry, men, who made up just 11% of the sample, had significantly higher rates of cardiogenic shock and were more than twice as likely to die in the hospital than their female counterparts.

The authors concluded that TSS in males requires close in-hospital monitoring and long-term follow-up. Their study was published in the Journal of the American College of Cardiology.

Takotsubo syndrome is a condition characterized by acute heart failure and transient ventricular contractile dysfunction that can be precipitated by acute emotional or physical stress. It affects mostly women, particularly postmenopausal women, although the reasons for this are still not fully clear, Luca Arcari, MD, from the Institute of Cardiology, Madre Giuseppina Vannini Hospital, Rome, and colleagues wrote.

The syndrome also affects men, and recent data have identified that male sex is associated with worse outcomes. But, because it occurs relatively uncommonly in men, information about outcomes in men is limited.

To shed more light on the influence of gender on TTS, the investigators looked at 2,492 TTS patients (286 men, 2,206 women) who were participants in the GEIST (German Italian Spanish Takotsubo) registry and compared the clinical features and short- and long-term outcomes between the two.

Male patients were significantly younger (69 years) than women (71 years; P = .005) and had a higher prevalence of comorbid conditions, including diabetes (25% vs. 19%; P = .01); pulmonary diseases (21% vs. 15%; P = .006); malignancies (25% vs. 13%; P < .001).

In addition, TTS in men was more likely to be caused by physical triggers (55% vs. 32%; P < .01), whereas emotional triggers were more common in females (39% vs. 19%; P < 0.001).

The investigators then performed a propensity score analysis by matching men and women 1:1; this yielded 207 patients from each group.

After propensity matching, male patients had higher rates of cardiogenic shock (16% vs 6%), and in-hospital mortality (8% vs. 3%; both P < .05).

Men also had a higher mortality rate during the acute and long-term follow up. Male sex remained independently associated with both in-hospital mortality (odds ratio, 2.26; 95% confidence interval, 1.16-4.40) and long-term mortality (hazard ratio, 1.83; 95% CI, 1.32-2.52).

The study by Dr. Arcari and colleagues “shows convincingly that although men are far less likely to develop TTS than women, they have more serious complications and are more likely to die than women presenting with the syndrome, Ilan S. Wittstein, MD, of Johns Hopkins University, Baltimore, wrote in an accompanying editorial.

In an interview, Dr. Wittstein said one of the strengths of the study was its size.

“Over the years, there have been a lot of smaller, single center studies. This large registry had over 2,000 patients. So when the researchers say the rate of TTS is 10% in men and 90% in women, this is not necessarily surprising because that’s about the breakdown we’ve had since the very beginning, but it certainly validates that in a cohort that is large,” he said.

“I think what was novel about the paper is that the size of the cohort allowed the researchers to do propensity matching, so they were able not only to compare men versus women, they could do a 1:1 comparison. And they found even when you match men and women for various comorbidities, the men were much sicker

“What makes this a fascinating syndrome and different from most types of heart muscle problems is that, in the majority of patients, the condition is precipitated by an acute stressor,” said Dr. Wittstein.

“It can either be an emotional trigger, so for instance, getting some bad news that a loved one just died. That’s why we nicknamed the syndrome ‘broken heart syndrome’ many years ago. Or it can be a physical trigger, which can be a wide variety of things, such infection, a stroke, bad pneumonia, anything that stresses the body and causes a stress response. Regular heart attacks are not triggered in this way,” he said.

Dr. Arcari and Dr. Wittstein reported no relevant financial relationships.

“It can either be an emotional trigger, so for instance, getting some bad news that a loved one just died. That’s why we nicknamed the syndrome ‘broken heart syndrome’ many years ago. Or it can be a physical trigger, which can be a wide variety of things, such infection, a stroke, bad pneumonia, anything that stresses the body and causes a stress response. Regular heart attacks are not triggered in this way,” he said.

Takotsubo syndrome occurs much more frequently in women than it does in men, but men are much more likely to die from it, according to the results of a new study.

In an analysis of almost 2,500 patients with Takotsubo syndrome (TSS) who were enrolled in an international registry, men, who made up just 11% of the sample, had significantly higher rates of cardiogenic shock and were more than twice as likely to die in the hospital than their female counterparts.

The authors concluded that TSS in males requires close in-hospital monitoring and long-term follow-up. Their study was published in the Journal of the American College of Cardiology.

Takotsubo syndrome is a condition characterized by acute heart failure and transient ventricular contractile dysfunction that can be precipitated by acute emotional or physical stress. It affects mostly women, particularly postmenopausal women, although the reasons for this are still not fully clear, Luca Arcari, MD, from the Institute of Cardiology, Madre Giuseppina Vannini Hospital, Rome, and colleagues wrote.

The syndrome also affects men, and recent data have identified that male sex is associated with worse outcomes. But, because it occurs relatively uncommonly in men, information about outcomes in men is limited.

To shed more light on the influence of gender on TTS, the investigators looked at 2,492 TTS patients (286 men, 2,206 women) who were participants in the GEIST (German Italian Spanish Takotsubo) registry and compared the clinical features and short- and long-term outcomes between the two.

Male patients were significantly younger (69 years) than women (71 years; P = .005) and had a higher prevalence of comorbid conditions, including diabetes (25% vs. 19%; P = .01); pulmonary diseases (21% vs. 15%; P = .006); malignancies (25% vs. 13%; P < .001).

In addition, TTS in men was more likely to be caused by physical triggers (55% vs. 32%; P < .01), whereas emotional triggers were more common in females (39% vs. 19%; P < 0.001).

The investigators then performed a propensity score analysis by matching men and women 1:1; this yielded 207 patients from each group.

After propensity matching, male patients had higher rates of cardiogenic shock (16% vs 6%), and in-hospital mortality (8% vs. 3%; both P < .05).

Men also had a higher mortality rate during the acute and long-term follow up. Male sex remained independently associated with both in-hospital mortality (odds ratio, 2.26; 95% confidence interval, 1.16-4.40) and long-term mortality (hazard ratio, 1.83; 95% CI, 1.32-2.52).

The study by Dr. Arcari and colleagues “shows convincingly that although men are far less likely to develop TTS than women, they have more serious complications and are more likely to die than women presenting with the syndrome, Ilan S. Wittstein, MD, of Johns Hopkins University, Baltimore, wrote in an accompanying editorial.

In an interview, Dr. Wittstein said one of the strengths of the study was its size.

“Over the years, there have been a lot of smaller, single center studies. This large registry had over 2,000 patients. So when the researchers say the rate of TTS is 10% in men and 90% in women, this is not necessarily surprising because that’s about the breakdown we’ve had since the very beginning, but it certainly validates that in a cohort that is large,” he said.

“I think what was novel about the paper is that the size of the cohort allowed the researchers to do propensity matching, so they were able not only to compare men versus women, they could do a 1:1 comparison. And they found even when you match men and women for various comorbidities, the men were much sicker
