CHICAGO — A preview of much-anticipated updates to guidelines on managing thyroid disease in pregnancy shows key changes to recommendations in the evolving field, ranging from consideration of the chance of spontaneous normalization of thyroid levels during pregnancy to a heightened emphasis on shared decision-making and the nuances can factor into personalized treatment.

The guidelines, expected to be published in early 2025, have not been updated since 2017, and with substantial advances and evidence from countless studies since then, the new guidelines were developed with a goal to start afresh, said ATA Thyroid and Pregnancy Guidelines Task Force cochair Tim IM Korevaar, MD, PhD, in presenting the final draft guidelines at the American Thyroid Association (ATA) 2024 Meeting.

“Obviously, we’re not going to ignore the 2017 guidelines, which have been a very good resource for us so far, but we really wanted to start from scratch and follow a ‘blank canvas’ approach in optimizing the evidence,” said Korevaar, an endocrinologist and obstetric internist with the Division of Pharmacology and Vascular Medicine & Academic Center for Thyroid Diseases, Department of Internal Medicine, Erasmus University Medical Center, Rotterdam, The Netherlands.

The guidelines, developed through a collaborative effort involving a wide variety of related medical societies, involved 14 systematic literature reviews. While the pregnancy issues covered by the guidelines is extensive, key highlights include:
 

Management in Preconception

Beginning with preconception, a key change in the guidelines will be that patients with euthyroid thyroid peroxidase (TPO) antibodies, which can be indicative of thyroid dysfunction, routine treatment with levothyroxine is not recommended, based on new evidence from randomized trials of high-risk patients showing no clear benefit from the treatment. 

“In these trials, and across analyses, there was absolutely no beneficial effect of levothyroxine in these patients [with euthyroid TPO antibody positivity],” he said.

With evidence showing, however, that TPO antibody positivity can lead to subclinical or overt hypothyroidism within 1 or 2 years, the guidelines will recommend that TPO antibody–positive patients do have thyroid stimulating hormone (TSH) levels tested every 3-6 months until pregnancy, and existing recommendations to test during pregnancy among those patients remain in place, Korevaar reported.

In terms of preconception subclinical hypothyroidism, the guidelines will emphasize the existing recommendation “to always strive to reassess” thyroid levels, and if subclinical hypothyroidism does persist, to treat with low-dose levothyroxine.
 

During Pregnancy

During pregnancy, the new proposed recommendations will reflect the important change that three key risk factors, including age over 30 years, having at least two prior pregnancies, and morbid obesity (body mass index [BMI] at least 40 kg/m²), previously considered a risk for thyroid dysfunction in pregnancy, should not, on their own, suggest the need for thyroid testing, based on low evidence of an increased risk in pregnancy.

Research on the issue includes a recent study from Korevaar’s team showing these factors to in fact have low predictability of thyroid dysfunction.

“We deemed that these risk differences weren’t really clinically meaningful (in predicting risk), and so we have removed to maternal age, BMI, and parity as risk factors for thyroid testing indications in pregnancy,” Korevaar said.

Factors considered a risk, resulting in recommended testing at presentation include a history of subclinical or clinical hypo- or hyperthyroidism, postpartum thyroiditis, known thyroid antibody positivity, symptoms of thyroid dysfunction or goiter, and other factors. 
 

Treatment for Subclinical Hypothyroidism in Pregnancy

Whereas current guidelines recommend TPO antibody status in determining when to consider treatment for subclinical hypothyroidism, the new proposed guideline will instead recommend treatment based on the timing of the diagnosis of the subclinical hypothyroidism, with consideration of treatment during the first trimester, but not in the second or third trimester, based on newer evidence of the absolute risk for pregnancy complications and randomized trial data.

“The recommendations are now to no longer based on TPO antibody status, but instead according to the timing of the diagnosis of subclinical hypothyroidism,” Korevaar said.

Based on the collective data, “due to the low risk, we do not recommend for routine levothyroxine treatment in the second or third trimester groups with TSH levels under 10 mU/L now.”

“However, for subclinical hypothyroidism diagnosed in the first trimester, the recommendation would be that you can consider levothyroxine treatment,” he said.

While a clear indication for treatment in any trimester is the presence of overt hypothyroidism, or TSH levels over 10 mU/L, Korevaar underscored the importance of considering nuances of the recommendations that may warrant flexibility, for instance among patients with borderline TSH levels.
 

Spontaneous Normalization of Thyroid Levels in Pregnancy

Another new recommendation addresses the issue of spontaneous normalization of abnormal thyroid function during pregnancy, with several large studies showing a large proportion of subclinical hypothyroidism cases spontaneously revert to euthyroidism by the third trimester — despite no treatment having been provided.

Under the important proposed recommendation, retesting of subclinical hypothyroidism is suggested within 3 weeks.

“The data shows that a large proportion of patients spontaneously revert to euthyroidism,” Korevaar said.

“Upon identifying subclinical hypothyroidism in the first trimester, there will be essentially two options that clinicians can discuss with their patient — one would be to consider confirmatory tests in 3 weeks or to discuss the starting the lower dose levothyroxine in the first trimester,” he said.

In terms of overt hypothyroidism, likewise, if patients have a TSH levels below 6 mU/L in pregnancy, “you can either consider doing confirmatory testing within 3 weeks, or discussing with the patient starting levothyroxine treatment,” Korevaar added.
 

Overt Hyperthyroidism

For overt hyperthyroidism, no significant changes from current guidelines are being proposed, with the key exception of a heightened emphasis on the need for shared decision-making with patients, Korevaar said.

“We want to emphasize shared decision-making especially for women who have Graves’ disease prior to pregnancy, because the antithyroid treatment modalities, primarily methimazole (MMI) and propylthiouracil (PTU), have different advantages and disadvantages for an upcoming pregnancy,” he said.

“If you help a patient become involved in the decision-making process, that can also be very helpful in managing the disease and following-up on the pregnancy.”

Under the recommendations, PTU remains the preferred drug in overt hyperthyroidism, due to a more favorable profile in terms of potential birth defects vs MMI, with research showing a higher absolute risk of 3% vs 5%.

The guidelines further suggest the option of stopping the antithyroid medications upon a positive pregnancy test, with the exception of high-risk patients.

Korevaar noted that, if the treatment is stopped early in pregnancy, relapse is not likely to occur until after approximately 3 months, or 12 weeks, at which time, the high-risk teratogenic period, which is between week 5 and week 15, will have passed.

Current guidelines regarding whether to stop treatment in higher-risk hyperthyroid patients are recommended to remain unchanged.
 

Thyroid Nodules and Cancer

Recommendations regarding thyroid nodules and cancer during pregnancy are also expected to remain largely similar to those in the 2017 guidelines, with the exception of an emphasis on simply considering how the patient would normally be managed outside of pregnancy. 

For instance, regarding the question of whether treatment can be withheld for 9 months during pregnancy. “A lot of times, the answer is yes,” Korevaar said.

Other topics that will be largely unchanged include issues of universal screening, definitions of normal and abnormal TSH and free T4 reference ranges and isolated hypothyroxinemia.
 

Steps Forward in Improving Updates, Readability

In addition to recommendation updates, the new guidelines are being revised to better reflect more recent evidence-based developments and user-friendliness.

“We have now made the step to a more systematic and replicable methodology to ensure for easier updates with a shorter interval,” Korevaar told this news organization.

“Furthermore, since 2006, the ATA guideline documents have followed a question-and-answer format, lacked recommendation tables and had none or only a few graphic illustrations,” he added. 

“We are now further developing the typical outline of the guidelines to improve the readability and dissemination of the guideline document.”

Korevaar’s disclosures include lectureship fees from IBSA, Merck, and Berlin Chemie.

TOPLINE:

Weight loss interventions using medication or behavioral changes can improve insulin resistance, hormonal markers, and menstrual frequency in women with polycystic ovary syndrome (PCOS), according to a new meta-analysis. Losing weight may not significantly reduce hirsutism or improve quality of life in women with the condition, however.

METHODOLOGY:

• Researchers systematically reviewed randomized controlled trials comparing weight loss interventions to usual care in women with PCOS.
• They focused on 12 studies with behavioral interventions (mainly diets with modest energy deficits), nine trials that used glucagon-like peptide 1 (GLP-1) receptor agonists, and eight studies using other weight loss medications.
• A total of 1529 participants were included in the analysis.
• The investigators synthesized the data using a random-effects meta-analysis with Knapp-Hartung adjustment to examine pooled mean differences.

TAKEAWAY:

• Menstrual frequency increased by 2.64 menses per year (95% CI, 0.65-4.63) with weight loss interventions.
• “To our knowledge, this is the first review to show a clinically significant association in improvement in menstrual frequency with weight loss interventions, an important indicator of subsequent fertility and an important outcome for women,” the researchers wrote.
• Glycemic control also improved, with a mean reduction in homeostatic model assessment of insulin resistance of 0.45 (95% CI, –0.75 to –0.15).
• Free androgen index decreased by an average of 2.03 (95% CI, –3.0 to –1.07).

IN PRACTICE:

“Clinicians may use these findings to counsel women with PCOS on the expected improvements in PCOS markers after weight loss and direct patients toward interventions,” the authors of the study wrote. “Because weight loss programs are cost-effective interventions to improve cardiometabolic risk, they may be particularly valuable for this population at elevated risk.”

SOURCE:

The study was led by Jadine Scragg, PhD, with the Nuffield Department of Primary Care Health Sciences at the University of Oxford in England. It was published online in Annals of Internal Medicine.

LIMITATIONS:

Interventions using GLP-1 agonists were dosed for glycemic control rather than weight management. The studies in the meta-analysis were relatively few and heterogeneous. Data were insufficient to assess ovulation and acne.

DISCLOSURES:

The meta-analysis was supported by grants from the National Institute for Health and Care Research School for Primary Care Research. Authors disclosed ties to Nestlé Health Science and Second Nature.

TOPLINE:

In women with polycystic ovary syndrome (PCOS) and with obesity or overweight, the combination of topiramate and metformin along with a low-calorie diet can result in effective weight loss and improve androgen levels, lipid levels, and psychosocial scores, without any serious adverse events.

METHODOLOGY:

• Topiramate is often used off-label for weight loss and may be a promising option added to a metformin regimen to improve cardiometabolic and reproductive health in women with PCOS and obesity or overweight when lifestyle changes alone fall short.
• This double-blind trial conducted at Hospital de Clínicas de Porto Alegre in Porto Alegre, Brazil, evaluated the effects of adding topiramate to metformin in 61 women aged 14-40 years with PCOS and body mass index (BMI) ≥ 30 or BMI ≥ 27 with concurrent hypertension, type 2 diabetes, or dyslipidemia.
• All participants were prescribed a 20 kcal/kg diet, as well as desogestrel for contraception during the study, and either started on 850 mg metformin or continued with their existing metformin regimen.
• They were randomly assigned to receive either topiramate or placebo (25 mg for 15 days and then 50 mg at night) along with metformin, with dose adjustments based on weight loss at 3 months.
• The primary outcome was the percent change in body weight from baseline, and the secondary outcomes included changes in clinical, cardiometabolic, and hormonal parameters and psychosocial features at 3 and 6 months.

TAKEAWAY:

• Topiramate combined with metformin resulted in greater mean weight loss at 3 months (−3.4% vs −1.6%; P = .03) and 6 months (−4.5% vs −1.4%; P = .03) than placebo plus metformin.
• Both treatment groups showed improvements in androgen and lipid levels and psychosocial scores, while the levels of C-reactive protein decreased only in the topiramate plus metformin group.
• Women who experienced ≥ 3% weight loss at 6 months showed a significant improvement in hirsutism scores (change in modified Ferriman-Gallwey scores, 8.4-6.5), unlike those who experienced < 3% weight loss (change in modified Ferriman-Gallwey scores, 8.02-8.78).
• Paresthesia was more common in the topiramate plus metformin group than in the metformin plus placebo group (23.3% vs 3.2%), but no serious adverse events were reported.

IN PRACTICE:

“In the era of new effective drugs for treating obesity, topiramate with metformin can be an option for women with obesity and PCOS, considering its low cost, reports of long-term experience with this medication, and ease to use,” the authors wrote.

The small sample size and high attrition rates were major limitations of this study. Increasing the topiramate dose at 3 months in those with < 3% weight loss did not provide additional benefit, and this study did not test for a higher topiramate dose response from the beginning, which could have potentially provided a better response to the medication. The small sample size of the study also prevented the authors from conducting a subgroup analysis.

DISCLOSURES:

The study was supported by research grants from the Conselho Nacional de Desenvolvimento Científico e Tecnológico, Brazil, and Fundação de Amparo à Pesquisa do Estado do Rio Grande do Sul, Brazil. The authors declared no conflicts of interest.

TOPLINE:

In women with polycystic ovary syndrome (PCOS) and with obesity or overweight, the combination of topiramate and metformin along with a low-calorie diet can result in effective weight loss and improve androgen levels, lipid levels, and psychosocial scores, without any serious adverse events.

METHODOLOGY:

• Topiramate is often used off-label for weight loss and may be a promising option added to a metformin regimen to improve cardiometabolic and reproductive health in women with PCOS and obesity or overweight when lifestyle changes alone fall short.
• This double-blind trial conducted at Hospital de Clínicas de Porto Alegre in Porto Alegre, Brazil, evaluated the effects of adding topiramate to metformin in 61 women aged 14-40 years with PCOS and body mass index (BMI) ≥ 30 or BMI ≥ 27 with concurrent hypertension, type 2 diabetes, or dyslipidemia.
• All participants were prescribed a 20 kcal/kg diet, as well as desogestrel for contraception during the study, and either started on 850 mg metformin or continued with their existing metformin regimen.
• They were randomly assigned to receive either topiramate or placebo (25 mg for 15 days and then 50 mg at night) along with metformin, with dose adjustments based on weight loss at 3 months.
• The primary outcome was the percent change in body weight from baseline, and the secondary outcomes included changes in clinical, cardiometabolic, and hormonal parameters and psychosocial features at 3 and 6 months.

TAKEAWAY:

• Topiramate combined with metformin resulted in greater mean weight loss at 3 months (−3.4% vs −1.6%; P = .03) and 6 months (−4.5% vs −1.4%; P = .03) than placebo plus metformin.
• Both treatment groups showed improvements in androgen and lipid levels and psychosocial scores, while the levels of C-reactive protein decreased only in the topiramate plus metformin group.
• Women who experienced ≥ 3% weight loss at 6 months showed a significant improvement in hirsutism scores (change in modified Ferriman-Gallwey scores, 8.4-6.5), unlike those who experienced < 3% weight loss (change in modified Ferriman-Gallwey scores, 8.02-8.78).
• Paresthesia was more common in the topiramate plus metformin group than in the metformin plus placebo group (23.3% vs 3.2%), but no serious adverse events were reported.

IN PRACTICE:

“In the era of new effective drugs for treating obesity, topiramate with metformin can be an option for women with obesity and PCOS, considering its low cost, reports of long-term experience with this medication, and ease to use,” the authors wrote.

The use of glucagon-like peptide 1 (GLP-1) agonists within a year had no apparent effect on the number of oocytes retrieved in controlled ovarian hyperstimulation (COH), based on data from 73 patients in a multicenter study.

Obesity rates continue to rise in women of reproductive age and many women are using GLP-1 agonists for weight loss, but data on the effect of these drugs on fertility treatments are lacking, said Victoria K. Lazarov, MD, of Icahn School of Medicine at Mount Sinai, New York City, in an abstract presented at the American Society for Reproductive Medicine (ASRM) 2024 scientific congress.

Clinical opinions regarding the use, duration, and discontinuation of GLP-1 agonists during fertility treatments are variable given the limited research, Lazarov noted in her abstract. More data are needed to standardize patient counseling.

Lazarov and colleagues reviewed data from patients who sought treatment at clinics affiliated with a national fertility network from 2005 to 2023 who also utilized a GLP-1 agonist within 1 year of COH.

The study population included 73 adult women; participants were divided into six groups based on the number of days without GLP-1 agonist use prior to retrieval (0-14, 15-30, 31-60, 61-90, 91-180, and 181-365 days). The primary outcome was oocyte yield following COH.

Overall, the mean oocyte yields were not significantly different across the six timing groups (14.4, 16.2, 16.8, 7.7, 13.8, and 15, respectively; P = .40).

In a secondary subgroup analysis, the researchers found an inverse relationship between oocyte yield and timing of GLP-1 agonist discontinuation in patients with body mass index (BMI) > 35. However, no changes in oocyte yield were observed in patients with BMIs in the normal or overweight range. Neither duration of GLP-1 agonist use or indication for use had a significant effect on oocyte yield across exposure group.

The findings were limited by several factors, including the relatively small study population, especially the small number of patients with obesity. “Additional investigation is needed to clarify potential effects of GLP-1 agonist use on aspiration risk during oocyte retrieval and embryo creation outcomes,” the researchers wrote in their abstract.

However, the results suggest that most women who use GLP-1 agonists experience no significant effects on oocyte retrieval and embryo creation, and that GLP-1 agonists may have a role in improving oocyte yield for obese patients, the researchers concluded.
 

Larger Studies Needed for Real Reassurance

“Infertility patients who are overweight have lower chances for conception and higher risks of pregnancy complications,” Mark Trolice, MD, professor at the University of Central Florida College of Medicine, Orlando, and founder/director of The IVF Center, Winter Park, Florida, said in an interview.

The use of GLP-1 agonists has dramatically increased given the medication’s effectiveness for weight loss, as well as its use to manage diabetes, but the use of GLP-1 agonists in pregnancy is not well known and current recommendations advise discontinuation of the medication for 6-8 weeks prior to conception, said Trolice, who was not involved in the study.

GLP-1 agonist use is associated with lowered blood glucose levels, Trolice said. “Additionally, the medication can delay gastric emptying and suppress appetite, both of which assist in weight management.”

The current study examined whether there was a difference in oocyte retrieval number in women based on days of discontinuation of GLP-1 agonists prior to the procedure, Trolice told this news organization. “Given the drug’s mechanism of action, there is no apparent biological influence that would impact oocyte yield. Consequently, the study outcome is not unexpected.”

The study purports potential reassurance that GLP-1 exposure, regardless of the duration of discontinuation, has no impact on egg retrieval number, said Trolice. However, “Based on the size of the study, to accept the findings as definitive would risk a type II statistical error.”

Two key areas for additional research are urgently needed, Trolice said, namely, the duration of time to discontinue GLP-1 agonists, if at all, prior to conception, and the discontinuation interval, if at all, prior to anesthesia to avoid airway complications.

The American Society of Anesthesiologists advises patients on daily dosing to consider holding GLP-1 agonists on the day of a procedure or surgery, and those on weekly dosing should consider discontinuing the medication 1 week before the procedure or surgery, Trolice noted.

The study received no outside funding. The researchers had no financial conflicts to disclose. Trolice had no financial conflicts to disclose and serves on the editorial advisory board of OB/GYN News.

Rachel S. Rubin, MD: I’m Dr. Rachel Rubin, a urologist and sexual medicine specialist in the Washington, DC, area. And I am so thrilled because my co-fellow, the brilliant and famous Dr. Ashley Winter, a board-certified urologist and a certified menopause practitioner, who sees patients in our practice from Los Angeles, is joining us today to talk about sex as a vital sign.

Ashley Winter, MD: To have the best sexual function, you need many different systems to work. You need your hormones to be in the right place. You need your blood vessels to dilate when you want them to. You need your nerves to connect to your genitalia to make them responsive. The way people say, “The eyes are the window into the soul” — well, the genitals are the window into the cardiovascular system, the peripheral nervous system, and the hormonal system. It’s so dynamic. Patients can understand how this reflects their health. We just need healthcare providers to hammer home how those things connect.

Rubin: If you’re a primary care doctor seeing a patient and you want to educate them on diabetes or high blood pressure, how can you “ ‘sell it with ‘sex”? How can you use sex to educate them about these important medical conditions?

Winter: I hate using it as a fear tactic, but sometimes you have to. Time and again, I’ve seen men with severe profound erectile dysfunction at a young age, with chronically uncontrolled diabetes.

Diabetes can impair the peripheral nerves, resulting in peripheral neuropathy. The same way that it can affect the fingers and toes, diabetes can affect the penis, even before those other areas. Diabetes can also lead to other conditions such as low testosterone, which also affects the function of the penis.

I’m being brutally honest when I tell patients that diabetes control is critical to having a wonderful sexspan — the duration of your life where you’re able to be sexually active and have great sex and do it in the way that you want.

Chronic conditions such as high cholesterol or hypertension can affect your ability to become erect or aroused whether you have a penis or a vulva, and even your ability to have an orgasm.

Rubin: None of my doctors has ever asked me about these issues. But we have to bring them up with patients because they›re not going to bring them up to us. I always say in the review of systems, we shouldn›t just ask, “Do you have any sexual problems?” (which nobody ever does) and move past the question about men, women or both. We should be asking, “Do you have any issues with libido? Do you want to talk about it? Any issues with erection, arousal, orgasm, or sexual pain?”

When you can talk about those things, you can treat the patient from a whole physiologic perspective. For example, how does their sciatica affect their sexual pain? How does their antidepressant cause a delayed orgasm? How does their low testosterone level affect their energy level, their libido, and their desire? 

We see so much shame and guilt in sexual health, to the extent that patients feel broken. We can help them understand the anatomy and physiology and explain that they aren’t broken. Instead, it’s “You need this medicine for your crippling anxiety, and that’s why your orgasm is delayed, and so can we augment it or add or subtract something to help you with it.”

Winter: In a primary care setting, where we are considering the patient›s overall health, we strive for medication compliance, but a huge part of medication noncompliance is sexual side effects, whether it›s antidepressants, beta-blockers, birth control, or this new world of GLP-1 agonists.

Rubin: I would add breast cancer treatments. Many patients go off their anastrozole or their tamoxifen because of the sexual side effects. 

Winter: This is where we get to the crux of this discussion about sex being a vital sign — something you need to check routinely. We need to become comfortable with it, because then we are unlocking the ability to treat every patient like a whole person, give them better outcomes, improve their compliance, and have a really powerful tool for education.

Rubin: We have a growing toolbox for all genders when it comes to sexual health. We have FDA- approved medications for low libido in women. We use testosterone in men in an evidence-based way to safely improve libido. We use medications to help with the genitourinary syndrome of menopause. Orgasm is a challenging one, but we have devices that can help with those reflexes. And working with people who specialize in sexual pain can be extremely helpful for patients.

Dr. Winter, having practiced in different settings, what would you tell the primary care doctors who don’t want to talk about libido or who minimize sexual complaints because they don’t know how to navigate them?

Winter: I do not envy the challenge of being a primary care provider in the healthcare world we are living in. I think it is the hardest job. The ultimate takeaway is to just normalize the conversation and be able to validate what is happening. Have a few basic tools, and then have referrals. It›s not that you have to have all the time in the world or you have to treat every condition, but you have to start the conversation, be comfortable with it, and then get patients hooked up with the right resources.

Rubin: Every doctor of every kind can connect with patients and try to understand what they care about. What are their goals? What do they want for their families, for their relationships, for their quality of life? And how can we work collaboratively as a team to help them with those things? 

Sex is a huge part of people’s lives. If we don’t ask about it; if we don’t look into it; and if we don’t admit that our physiology, our medications, and our surgeries can affect sexual health and functioning, how can we improve people’s lives? We can do so much as a team when we consider sex as a true vital sign.

The way people say, “The eyes are the window into the soul” — well, the genitals are the window into the cardiovascular system, the peripheral nervous system, and the hormonal system. It’s so dynamic. Patients can understand how this reflects their health. We just need healthcare providers to hammer home how those things connect.

Rubin: If you’re a primary care doctor seeing a patient and you want to educate them on diabetes or high blood pressure, how can you “ ‘sell it with ‘sex”? How can you use sex to educate them about these important medical conditions?

Winter: I hate using it as a fear tactic, but sometimes you have to. Time and again, I’ve seen men with severe profound erectile dysfunction at a young age, with chronically uncontrolled diabetes.

Diabetes can impair the peripheral nerves, resulting in peripheral neuropathy. The same way that it can affect the fingers and toes, diabetes can affect the penis, even before those other areas. Diabetes can also lead to other conditions such as low testosterone, which also affects the function of the penis.

I’m being brutally honest when I tell patients that diabetes control is critical to having a wonderful sexspan — the duration of your life where you’re able to be sexually active and have great sex and do it in the way that you want.

Chronic conditions such as high cholesterol or hypertension can affect your ability to become erect or aroused whether you have a penis or a vulva, and even your ability to have an orgasm.

Rubin: None of my doctors has ever asked me about these issues. But we have to bring them up with patients because they›re not going to bring them up to us. I always say in the review of systems, we shouldn›t just ask, “Do you have any sexual problems?” (which nobody ever does) and move past the question about men, women or both. We should be asking, “Do you have any issues with libido? Do you want to talk about it? Any issues with erection, arousal, orgasm, or sexual pain?”

When you can talk about those things, you can treat the patient from a whole physiologic perspective. For example, how does their sciatica affect their sexual pain? How does their antidepressant cause a delayed orgasm? How does their low testosterone level affect their energy level, their libido, and their desire? 

We see so much shame and guilt in sexual health, to the extent that patients feel broken. We can help them understand the anatomy and physiology and explain that they aren’t broken. Instead, it’s “You need this medicine for your crippling anxiety, and that’s why your orgasm is delayed, and so can we augment it or add or subtract something to help you with it.”

Winter: In a primary care setting, where we are considering the patient›s overall health, we strive for medication compliance, but a huge part of medication noncompliance is sexual side effects, whether it›s antidepressants, beta-blockers, birth control, or this new world of GLP-1 agonists.

Rubin: I would add breast cancer treatments. Many patients go off their anastrozole or their tamoxifen because of the sexual side effects. 

Winter: This is where we get to the crux of this discussion about sex being a vital sign — something you need to check routinely. We need to become comfortable with it, because then we are unlocking the ability to treat every patient like a whole person, give them better outcomes, improve their compliance, and have a really powerful tool for education.

Rubin: We have a growing toolbox for all genders when it comes to sexual health. We have FDA- approved medications for low libido in women. We use testosterone in men in an evidence-based way to safely improve libido. We use medications to help with the genitourinary syndrome of menopause. Orgasm is a challenging one, but we have devices that can help with those reflexes. And working with people who specialize in sexual pain can be extremely helpful for patients.

Dr. Winter, having practiced in different settings, what would you tell the primary care doctors who don’t want to talk about libido or who minimize sexual complaints because they don’t know how to navigate them?

Winter: I do not envy the challenge of being a primary care provider in the healthcare world we are living in. I think it is the hardest job. The ultimate takeaway is to just normalize the conversation and be able to validate what is happening. Have a few basic tools, and then have referrals. It›s not that you have to have all the time in the world or you have to treat every condition, but you have to start the conversation, be comfortable with it, and then get patients hooked up with the right resources.

Rubin: Every doctor of every kind can connect with patients and try to understand what they care about. What are their goals? What do they want for their families, for their relationships, for their quality of life? And how can we work collaboratively as a team to help them with those things? 

Sex is a huge part of people’s lives. If we don’t ask about it; if we don’t look into it; and if we don’t admit that our physiology, our medications, and our surgeries can affect sexual health and functioning, how can we improve people’s lives? We can do so much as a team when we consider sex as a true vital sign.

TOPLINE:

Adolescent girls with polycystic ovary syndrome (PCOS) have an increased risk for hypertension, according to a new study which underscores the importance of blood pressure surveillance in this population.

METHODOLOGY:

• The retrospective cohort study examined the association between PCOS and hypertension in adolescent girls within a diverse community-based US healthcare population.
• The researchers analyzed data from 224,418 adolescent girls (mean age at index visit, 14.9 years; 15.8% classified as having obesity) who had a well-child visit between 2013 and 2019, during which their systolic blood pressure and diastolic blood pressure were measured.
• Blood pressure in the hypertensive range was classified using the 2017 American Academy of Pediatrics Practice Guideline, with thresholds of 130/80 mm Hg or greater.

TAKEAWAY:

• The proportion of adolescent girls with high blood pressure was significantly greater among those with PCOS than among those without the condition (18.2% vs 7.1%; P < .001).
• Adolescent girls with PCOS had a 25% higher risk for hypertension than those without the disorder (adjusted odds ratio [aOR], 1.25; 95% CI, 1.10-1.42).
• Similarly, adolescent girls with obesity and PCOS had a 23% higher risk for high blood pressure than those without PCOS (aOR, 1.23; 95% CI, 1.06-1.42).

IN PRACTICE:

“The high prevalence of [hypertension] associated with PCOS emphasizes the key role of early [blood pressure] monitoring in this high-risk group,” the authors of the study wrote.

SOURCE:

The study was led by Sherry Zhang, MD, Kaiser Permanente Oakland Medical Center, Oakland, California, and was published online in the American Journal of Preventive Medicine.

LIMITATIONS:

The study relied on coded diagnoses of PCOS from clinical settings, which may have led to detection and referral biases. The findings may not be generalizable to an unselected population in which adolescent girls are systematically screened for both PCOS and hypertension.

DISCLOSURES:

This study was funded by the Cardiovascular and Metabolic Conditions Research Section and the Biostatistical Consulting Unit at the Division of Research, Kaiser Permanente Northern California and by the Kaiser Permanente Northern California Community Health Program. The authors declared having no conflicts of interest.

Thanks to the continuously improving treatment options for cancer, the number of cancer survivors is increasing, and a large proportion of survivors is confronted with the long-term effects of cancer treatment. Especially for young patients, the question of the impact of therapy on fertility arises.

Dose adjustment or modification of the treatment regimen can achieve a lot. But experts at the congress of the European Society for Medical Oncology (ESMO) 2024 noted that knowledge about newer treatment options like immunotherapies is still insufficient.
 

Therapy Selection

The question of preserving fertility must be considered when deciding on the appropriate treatment, said Matteo Lambertini, MD, PhD, medical oncology consultant at the University of Genoa in Genoa, Italy. A patient’s age, the type of therapy, and the dose are crucial in determining whether or how much fertility is affected. “Preserving fertility is also an aim of cancer therapy,” he said.

Lambertini, who is also a member of the ESMO Guideline Group on fertility preservation in cancer patients, referred to the 2020 ESMO guidelines, which list the gonadotoxicity of a substance depending on the treatment regimen and the patient’s age.

Isabelle Demeestere, MD, PhD, director of the research lab for human reproduction at the Erasmus Hospital of the Free University of Brussels in Brussels, Belgium, pointed out the limitations of general guidelines. “Therapies change over time, and a classification must be updated regularly.”

Knowledge gaps related to well-known therapies and many novel options persist. “For many FDA-approved medications, there are either no fertility data or only preclinical data available,” she added.
 

Chemotherapies and Immunotherapies

Chemotherapies with alkylating or platinum-containing substances are known for their effects on oocytes, follicle maturation, and spermatogenesis, said Demeestere.

Chemotherapy is gonadotoxic and leads to a temporary decrease in sperm quality or temporary azoospermia in men.

These effects, however, can lead to permanent azoospermia and endocrine disorders, depending on the dose, duration, or combination with radiation, said Demeestere.

Cryopreservation of sperm should always be performed before starting treatment. For high-risk patients who are prepubertal, samples of testicular tissue are taken.

In women, chemotherapy affects primordial follicles and follicle maturation through DNA damage. This process results in severe or temporary amenorrhea, a temporary or permanent decrease in egg reserve, and ultimately premature egg insufficiency.

Novel immunotherapies also influence fertility, presumably through interactions of the immune system with the reproductive organs. But insufficient data are available, according to Lambertini, who emphasized that “these data are urgently needed, especially for young patients with cancer.”

In a mouse model, immune checkpoint inhibitors affected ovarian function, and the inflammatory reaction in humans can affect fertility. No long-term data are available for women yet, however, explained Demeestere. The effects of other therapeutics such as PARP, CDK4/6, or tyrosine kinase inhibitors, as well as monoclonal antibodies like trastuzumab, are only seen sporadically.

In the PENELOPE-B phase 3 study, the CDK4/6 inhibitor palbociclib did not affect ovarian function, even though the cyclin-dependent kinases play an important role in mitotic arrest, said Demeestere.
 

Adjusting the Regimen

In a PET-guided approach, Demeestere’s research team investigated the effects of dose reduction or adjustment of the treatment regimen of procarbazine and cyclophosphamide on the fertility of patients younger than 45 years with advanced Hodgkin lymphoma.

By regularly controlling tumor growth with PET, the treatment could be adjusted so that the effect on egg reserve or spermatogenesis was significantly reduced and loss of fertility could be prevented.

During the 5-year follow-up period, the ovarian function of participating women was assessed by the serum concentration of follicle-stimulating hormone (FSH), estradiol, and anti-Müllerian hormone (AMH) to evaluate egg reserve. In men, testicular function was assessed at the beginning of the study. At the end of treatment, sperm analysis and FSH and testosterone levels were checked.

Demeestere and colleagues demonstrated that dose reduction or altering the treatment regimen for patients who responded early to treatment (determined by PET-guided monitoring) reduced the risk for gonadotoxicity from 46% to 14.5%. That is, the risk was reduced by more than half.

FSH and AMH correlated with the patient’s age and the dose of the alkylating agent. In men, sperm parameters recovered after dose or agent adjustment compared with the unchanged treatment regimen.

Newer results from the PHERGain study in women with early human epidermal growth factor receptor 2–positive breast cancer also provided hope, according to Demeestere. Under PET-guided control, chemotherapy could be reduced.
 

More Data Needed

The new treatment options pose a challenge to preserving fertility during cancer treatment, said Demeestere.

For new targeted therapies, uniform recommendations cannot be issued because of the lack of data and varying treatment durations. Still, the new therapies are safer than chemotherapy.

The need to collect data on fertility and long-term effects in cancer survivors in clinical studies is also reflected in the literature, according to Demeestere. “There are more review articles on this topic than clinical studies.”

TOPLINE: 

Women with premature ovarian insufficiency (POI) have a 2.6 times higher prevalence of severe autoimmune diseases before diagnosis and a 2- to 3-fold increased risk for these diseases after diagnosis.
 

METHODOLOGY:

• Researchers conducted a population-based registry study including 3972 women diagnosed with spontaneous POI between 1988 and 2017.
• A total of 15,708 female population controls matched by age and municipality of residence were included for comparison.
• Autoimmune disease diagnoses were evaluated from childhood until the end of 2017 using the Hospital Discharge Registry.
• Women with a history of cancer or bilateral oophorectomy were excluded from the study.

TAKEAWAY:

• Women with POI had a 2.6 times higher prevalence of severe autoimmune diseases before diagnosis compared to controls (odds ratio [OR], 2.6; 95% CI, 2.2-3.1).
• The prevalence of specific autoimmune diseases such as polyglandular autoimmune diseases (OR, 25.8; 95% CI, 9.0-74.1) and Addison disease (OR, 22.9; 95% CI, 7.9-66.1) was significantly higher in women with POI.
• The standardized incidence ratios for being diagnosed with a severe autoimmune disease after POI diagnosis was 2.8 (95% CI, 2.3-3.4) during the first 3 years, decreasing to 1.3 (95% CI, 1.1-1.6) after 12 years.
• No significant difference was found in the prevalence of diabetes type 1 and ankylosing spondylitis between women with POI and the reference cohort.

IN PRACTICE:

“The study results strengthen the hypothesis that autoimmune mechanisms play an important role in the pathogenesis of POI. Future studies should focus on the immunological mechanism of POI from preventative and curative perspectives,” wrote the authors of the study.

SOURCE:

The study was led by Susanna M. Savukoski, Oulu University Hospital in Finland. It was published online in Human Reproduction.

LIMITATIONS: 

The study included only autoimmune disorders diagnosed in specialized health care, which may underestimate the overall prevalence of autoimmune disorders in women with POI. Additionally, the study did not account for confounders such as body mass index and smoking, which are associated with the risk for autoimmune disease and POI.

DISCLOSURES:

Ms. Savukoski received grants from the Finnish Menopause Society, the Finnish Medical Foundation, and the Juho Vainio Foundation. Additional disclosures are noted in the original article.

• Women with POI had a 2.6 times higher prevalence of severe autoimmune diseases before diagnosis compared to controls (odds ratio [OR], 2.6; 95% CI, 2.2-3.1).
• The prevalence of specific autoimmune diseases such as polyglandular autoimmune diseases (OR, 25.8; 95% CI, 9.0-74.1) and Addison disease (OR, 22.9; 95% CI, 7.9-66.1) was significantly higher in women with POI.
• The standardized incidence ratios for being diagnosed with a severe autoimmune disease after POI diagnosis was 2.8 (95% CI, 2.3-3.4) during the first 3 years, decreasing to 1.3 (95% CI, 1.1-1.6) after 12 years.
• No significant difference was found in the prevalence of diabetes type 1 and ankylosing spondylitis between women with POI and the reference cohort.

IN PRACTICE:

“The study results strengthen the hypothesis that autoimmune mechanisms play an important role in the pathogenesis of POI. Future studies should focus on the immunological mechanism of POI from preventative and curative perspectives,” wrote the authors of the study.

SOURCE:

The study was led by Susanna M. Savukoski, Oulu University Hospital in Finland. It was published online in Human Reproduction.

LIMITATIONS: 

The study included only autoimmune disorders diagnosed in specialized health care, which may underestimate the overall prevalence of autoimmune disorders in women with POI. Additionally, the study did not account for confounders such as body mass index and smoking, which are associated with the risk for autoimmune disease and POI.

DISCLOSURES:

Ms. Savukoski received grants from the Finnish Menopause Society, the Finnish Medical Foundation, and the Juho Vainio Foundation. Additional disclosures are noted in the original article.

A study by researchers at two academic medical centers determined which infertile men may benefit from treatment with anastrozole. They found that those with azoospermia (no sperm in their ejaculate) rarely respond to the drug while those with baseline nonazoospermia, lower levels of luteinizing hormone and follicle-stimulating hormone, and higher levels of testosterone are more likely to obtain improvement in semen parameters.

The retrospective cohort study of 90 infertile men, published in the October 2023 issue of Fertility and Sterility, was conducted by researchers at Cleveland Clinic and the University of California Los Angeles. It is the first project of Male Organ Biology Yielding United Science (MOBYUS), a new, multi-institutional research consortium seeking to better understand male infertility and expand treatment options. 

Launched last year, MOBYUS now includes investigators from 14 large US-based academic medical centers. They select research topics and search their patient population for eligible participants and share resulting deidentified data for analysis and publication. 

Members of the consortium conducted another study which found that combination therapy with clomiphene citrate and anastrozole was associated with modest benefits on semen parameters, including volume, concentration, and motility after treatment, compared with anastrozole monotherapy. That retrospective cohort analysis of 21 men was published online in Translational Andrology and Urology in February. 

“We know that if we treat the right men with these medications, about 40% will improve their fertility, but only if we choose the right population. These studies identified those groups,” Scott Lundy, MD, PhD, section head of male infertility at Cleveland Clinic’s Glickman Urological and Kidney Institute in Cleveland, and director of the clinic’s andrology lab, told Medscape Medical News. 

Dr. Lundy, a coauthor of both papers, conceived MOBYUS to overcome constraints in research into male infertility. Many studies in the field are limited by small numbers of patients and retrospective designs, he said. “I sought to develop a collaborative network of reproductive urologists and hospitals like ours, so that we can combine our data and generate large series of data, even for rare patient groups, so that we can improve their patient outcomes,” he said.

“Our treatments are in the stone age in many ways. We are far behind other types of treatment for other conditions, including female infertility,” Dr. Lundy added. “And so, our goal is to identify new and data-driven ways to help these men become fathers, whether those are medications or surgeries or combinations of treatments.”
 

Moving the Field Forward

The name of the consortium is a cheeky play on Moby Dick, the most famous sperm whale. MOBYUS investigators conveyed the challenges that patients, doctors, and researchers experience in an article published last December in the Journal of Urology. 

They noted that 1 in 6 couples will have difficulty conceiving a child, with male-factor infertility contributing to at least half of such cases. The lead author, Catherine Nam, MD, a principal investigator for MOBYUS at the University of Michigan, in Ann Arbor, said the paper is unusual for a medical journal, as it provides personal accounts of the psychological and emotional aspects of infertility as well as factors that have led to a global decline in sperm counts among men and the financial costs of treatment.

Dr. Nam said infertility is a sensitive topic for couples and families to talk about and there is less conversation about male infertility than female infertility. “I think the only way that we can be able to make headway, both in terms of protocol and policy outcomes, is to really start to raise awareness,” said Dr. Nam, who is doing a fellowship in clinical andrology at Northwestern University, in Chicago.

Dr. Nam said the collaborative environment of MOBYUS has enabled her to learn about different practice patterns across different institutions. “For someone like me just starting off my professional career in male infertility, an opportunity like this is incredibly exciting and makes me very hopeful about the kinds of collaboration and scientific discovery that we’re able to do together as a group,” she said.

Robert E. Brannigan, MD, vice chair of clinical urology at Northwestern University Feinberg School of Medicine, Chicago, said the consortium is drawing on the strength of many individual centers and allowing them to study critical issues in the field. The group’s outstanding clinicians and scientists “are looking to move the field forward, and I applaud them and I’m eager to watch things unfold,” said Dr. Brannigan, who is not a member of the group.

Dr. Brannigan noted that for a large percentage of patients, clinicians cannot identify the root cause of their impaired reproductive potential. Some people may have a recognizable decline in semen parameters over time without clear lifestyle issues or clear hormonal imbalances or anatomical problems. 

“And the question is, what’s causing that? Is there some as yet unrecognized environmental exposure? Is there some underlying genetic issue that’s predisposing to decline in semen parameters over time? We see this, and we don’t have answers,” Dr. Brannigan said. 

“This is where I think the potential power of a large group like MOBYUS comes into play,” he added. “When you’ve got large datasets and very granular information about your patients, sometimes that can provide the opportunity for insights that can then answer the question, ‘What is the root cause of my patient’s challenges?’ ”

Dr. Brannigan was part of a previous group, the Andrology Research Consortium, which collected data on patient history and treatment through a standardized questionnaire. The consortium was founded in 2013 by the Society for the Study of Male Reproduction, a specialty section of the American Urological Association, to obtain data on the demographics, clinical characteristics, and fertility histories and therapies of men referred for a male infertility investigation at clinics across North America. 

Clinicians analyzed data from the questionnaires, which a team in Toronto collected and stored, in a series of studies, including a comparison of fertility characteristics between men in the United States and Canada. Dr. Brannigan said MOBYUS is poised to produce a large dataset that can address retrospective questions and potentially prospectively collect data to answer prospective questions.
 

Clinical Implications

Dr. Lundy said between 100 and 200 practicing reproductive urologists across the country regularly communicate with each other. He first raised the idea of creating a consortium with friends and colleagues and then discussed it at scientific meetings. The network steadily gained traction and is continuing to add institutions. “There’s a great deal of excitement in our community about this,” Dr. Lundy said.

MOBYUS, which is IRB approved, has a database with data from more than 4000 patients. The consortium has not received any industry funding but plans to pursue grant applications in the future. 

The MOBYUS website includes a list of its member institutions and leading investigators and its three proof-of-principle manuscripts published to date. The team identifies new research projects at monthly virtual meetings.

Dr. Lundy said MOBYUS’ main goal is to identify a treatment that will change the avenue available for a couple to get pregnant. For example, he said, if a man has zero sperm in his semen, he often requires surgery to find and remove sperm from the testicle. If medications can produce low sperm counts, sperm found in the ejaculate can be frozen and surgery can be avoided. 

Dr. Lundy said MOBYUS’ two publications on medical therapies have changed clinical practice, as he and many others have begun to provide the treatments on more carefully selected patients with good outcomes. 

Dr. Nam said patients want to know what they can expect from therapies and these research findings will have “a lot of clinical implications” in counseling them. 

The MOBYUS team will be describing the consortium and its goals in an abstract presentation at the American Society for Reproductive Medicine Scientific Congress & Expo, to be held October 19-23 in Denver, Colorado, and in an oral presentation at the Sexual Medicine Society of North America’s annual fall scientific meeting, to be held October 17-20 in Scottsdale, Arizona.

TOPLINE:

Women with hyperandrogenic polycystic ovary syndrome (PCOS) have lower pregnancy (29.9%) and live birth rates (20.1%) than those with nonhyperandrogenic PCOS (40.2% and 33.1%, respectively).

METHODOLOGY:

• Researchers conducted a retrospective cohort study of 1376 participants from the PPCOS I and II trials, all meeting National Institutes of Health diagnostic criteria for PCOS.
• Participants were categorized into hyperandrogenic (A and B) and nonhyperandrogenic (D) PCOS phenotypes on the basis of medical interviews, demographics, physical examinations, and laboratory data.
• Outcomes of interest included clinical pregnancy, pregnancy loss, live birth, obstetric complications, and neonatal outcomes.
• Fasting blood samples were analyzed for hormonal assays, and Homeostatic Model Assessment for Insulin Resistance scores were calculated using fasting glucose and insulin values.

TAKEAWAY:

• Participants with hyperandrogenic PCOS had higher body mass index (35.5 ± 8.9 vs 31.9 ± 9.3; P < .001) and fasting insulin levels (21.6 ± 27.7 vs 14.7 ± 15.0 μIU/mL; P < .001) than those with nonhyperandrogenic PCOS.
• Participants with hyperandrogenic PCOS had lower odds of achieving pregnancy (odds ratio [OR], 0.63; 95% CI, 0.44-0.92) and live birth (OR, 0.51; 95% CI, 0.34-0.76) than those with nonhyperandrogenic PCOS.
• No significant differences were found in pregnancy loss rates (23.9% vs 32.3%, P = .06) or neonatal outcomes between the two groups.
• The study lacked the power to detect differences in neonatal outcomes because of the low prevalence of these outcomes.

IN PRACTICE:

“Patients with nonhyperandrogenic PCOS may represent a different disease process with unique morbidities and outcomes and could be counseled differently than hyperandrogenic PCOS,” wrote the authors of the study.

SOURCE:

The study was led by Jessica L. Chan, MD, MSCE, Cedars-Sinai Medical Center in Los Angeles, California. It was published online in Obstetrics & Gynecology.

LIMITATIONS:

The primary limitation of this study was that it is a secondary analysis of previously collected randomized controlled trial data, which may affect the availability of certain information. Additionally, the lower number of participants in the nonhyperandrogenic PCOS group could affect the power of the results. The study was underpowered to detect statistically significant differences in neonatal outcomes because of their low prevalence.

DISCLOSURES:

The study was supported by a grant from the ASRM/NICHD/Duke Clinical Research/Reproductive Scientist Training Program. One coauthor disclosed receiving payments from Celmatix, Ferring Pharmaceuticals, Exeltis, Organon, and Monsanto; another disclosed receiving payments from Ferring Pharmaceuticals.
