Levonorgestrel intrauterine devices (LNG IUD) are a hot topic in contraceptive research. A recent study on LNG IUDs published by Fay KE et al evaluated pregnancy rates in US women who received LNG or copper IUDs for emergency contraception and reported intercourse within 7 days of insertion. Zero pregnancies were reported in women who resumed intercourse within 7 days of IUD insertion for both the LNG IUD and copper IUD, even in women who had multiple unprotected sexual encounters. LNG IUDs are more readily accessible and better tolerated than their copper IUD counterparts, and expanding their use will only continue to improve access to reliable contraception. Women often resume penetrative intercourse shortly after initiating new contraceptive method despite counseling. Patients can be reassured that placement of a LNG IUD appears to provide immediate contraceptive benefit.
A new estrogen is on the market for use in combined oral contraceptive pills (COC). Estetrol is a natural estrogen produced by the human fetal liver only found in circulation during pregnancy. Estetrol was previously studied for use in menopausal hormone therapy as it acts as a mixed agonist and antagonist, offering a potential improved side effect profile with less activity in the breast and liver. Estetrol (15 mg) was combined with 3 mg of drospirinone for a novel combined oral contraceptive option in a study by Gemzell-Danielsson K et al. The pregnancy rate was similar to traditional COCs, demonstrating good contraceptive efficacy. Bleeding patterns and side effects were similar to traditional COCs, and one case of venous thromboembolism was reported in the large study population. A phase III trial with similar results has been completed and this new oral contraceptive formulation recently received FDA approval and is now marketed as Nextstellis. This new oral contraceptive pill hopefully represents a novel option for women who desire COCs with a low androgenic profile and VTE risk or have failed other COC formulations.
Women are increasingly delaying childbearing, utilizing a variety of contraceptive options to avoid pregnancy. Many proactively seek to determine their fertility potential and clinicians often utilize anti-Müllerian hormone (AMH) as the standard biomarker for assessing ovarian reserve, as it is cycle independent and can be drawn at any time during a woman’s clinical assessment. Hormonal contraception suppresses ovulation by gonadotropin suppression as a means of contraceptive action, and thus could impact an AMH value. A fascinating study by Hariton E et al looked at all contraceptive options and their impact on AMH values. AMH levels were significantly lower in women using COCs, implants, progestin-only pills, and vaginal rings compared to patients not using contraceptives, and AMH levels were slightly lower in women using hormonal IUDs. These results help clinicians counsel patients on expectations for AMH levels while on contraceptives and can guide future research to generate contraceptive-specific ranges. Women using contraceptives should be counseled to retest after stopping if AMH levels are low.
