Although numerous studies have addressed the safety and effectiveness of hormonal contraceptive use in healthy women, data regarding women with underlying medical conditions or other special circumstances are limited. The U.S. Medical Eligibility Criteria (USMEC) for Contraceptive Use, 2016 (), which has been endorsed by the American College of Obstetricians and Gynecologists, is a published guideline based on the best available evidence and expert opinion to help health care providers better care for women with chronic medical problems who need contraception. The goal of this Practice Bulletin is to explain how to use the USMEC rating system in clinical practice and to specifically discuss the rationale behind the ratings for various medical conditions. Contraception for women with human immunodeficiency virus (HIV) (); the use of emergency contraception in women with medical coexisting medical conditions, including obesity, (); and the effect of depot medroxyprogesterone acetate (DMPA) on bone health () are addressed in other documents from the American College of Obstetricians and Gynecologists.

Emergency contraception, also known as postcoital contraception, is therapy used to prevent pregnancy after an unprotected or inadequately protected act of sexual intercourse. Common indications for emergency contraception include contraceptive failure (eg, condom breakage or missed doses of oral contraceptives) and failure to use any form of contraception (1-3). Although oral emergency contraception was first described in the medical literature in the 1960s, the U.S. Food and Drug Administration (FDA) approved the first dedicated product for emergency contraception in 1998. Since then, several new products have been introduced. Methods of emergency contraception include oral administration of combined estrogen-progestin, progestin only, or selective progesterone receptor modulators and insertion of a copper intrauterine device (IUD). Many women are unaware of the existence of emergency contraception, misunderstand its use and safety, or do not use it when a need arises (4-6). The purpose of this Practice Bulletin is to review the evidence for the efficacy and safety of available methods of emergency contraception and to increase awareness of these methods among obstetrician-gynecologists and other gynecologic providers.

Patients are often unaware of the non-contraceptive benefits of hormonal contraception. and this represents an opportunity for counseling (2). A brief list of some common non-contraceptive benefits is provided in Box I.
Most hormonal contraceptives combine progestin for its contraceptive effects and an estrogen to stabilize the endometrium and reduce unwanted spocane. Users progestin-only hormonal contraceptives avoid the sile citects associated with the use of contraceptives containing estrogen. Progestin-only contraceptives often can be used in women when estrogen is contraindicated; however, unpredictable spotting may be problematic for some patients. Over time, this unwanted bleeding generally subsides and progestin-only methods may provide highly effective long-term contraception.
Since oral contraceptives containing 150 micrograms or mestranol were introduced in ryo0, the dose of estrogen per pill has been reduced: current bills may. . .
Doxycycline and other antibiotics have been implicated in oral contraceptive (OC) failure, but information is sparse and studies of a doxycycline-OC interaction are nonexistent. Because an interaction between doxycycline and OCs, especially those containing low-dose estrogen, could result in an unplanned and unwanted pregnancy, a controlled clinical trial of the effects of doxycycline on OC hormone concentrations was performed. Twenty-four women aged 18-35 years were recruited as volunteers from among the patients seen in a University-based family planning clinic. While they were on a steady dose of the OC Ortho-Novum 1/35, serum concentrations of ethinyl estradiol, norethindrone, and endogenous progesterone were measured on days 18, 19, and 20 of the menstrual cycle (control phase). These measurements were repeated on days 18, 19, and 20 of the following menstrual cycle while the patient was taking doxycycline, 100 mg twice daily (treatment phase). No statistically significant differences in serum levels of ethinyl estradiol, norethindrone, or endogenous progesterone were seen between the control and treatment phases. However, there was large inter-patient and intra-patient variability in ethinyl estradiol and norethindrone levels. No elevations of endogenous progesterone occurred to suggest ovulation during antibiotic administration in either phase. It is not known what effects longer or earlier administration of doxycycline during the OC cycle would have on serum hormone concentrations or ovulation. Pregnancies attributed to failure of OCs because of tetracycline use could in fact be due to other causes or could represent a true interaction that only manifests itself in a small proportion of women at risk.

Hormonal contraceptives (HCs) are widely used, yet their effects on emotional and cognitive processes remain poorly understood. This study examined how HC use may influence emotional reactivity, emotion regulation, and emotional memory. Female participants (N = 179), either using HCs (N = 87) or naturally cycling (NC; N = 92), were randomly assigned to one of three groups: no emotion regulation (control), distancing and immersion, or reinterpretation and immersion. The emotion regulation groups completed emotion regulation training in which they viewed emotional images while applying different emotion regulation strategies, followed by a surprise memory test. Overall, HC users showed greater emotional reactivity to emotional images compared to NC participants. Both HC and NC groups successfully applied emotion regulation strategies as measured by changes in emotional affect; however, distancing led to a greater reduction in negative emotions compared to reinterpretation, particularly among HC users. Both HC and NC groups showed better memory for positive images after applying immersion. For negative images, HC users showed reduced memory performance when applying either distancing or reinterpretation, an effect not observed in NC participants. These findings suggest that HC use may influence specific aspects of emotional processing and memory, highlighting the need for more nuanced research on the cognitive and emotional effects of hormonal contraceptives.
