Threatened miscarriage is a common complication of early pregnancy characterized by symptoms of vaginal bleeding with/without abdominal cramps/pain in the first trimester. Progestogens are often administered for management of this condition. Presented herein is the protocol of an ongoing, multicentric clinical trial to investigate the efficacy and safety of micronized progesterone (natural progestogen) compared to dydrogesterone (synthetic isomer of progesterone).

Study Question: Is there an association between dydrogesterone exposure during early pregnancy and the reporting of birth defects?
Summary Answer: This observational analysis based on global safety data showed an increased reporting of birth defects, mainly hypospadias and congenital heart defects (CHD), in pregnancies exposed to dydrogesterone, especially when comparing to progesterone.
What Is Known Already: Intravaginal administration of progesterone is the standard of care to overcome luteal phase progesterone deficiency induced by ovarian stimulation in ART. In recent years, randomized controlled clinical trials demonstrated that oral dydrogesterone was non-inferior for pregnancy rate at 12 weeks of gestation and could be an alternative to micronized vaginal progesterone.

Endometriosis affects about 10 percent women in the reproductive age group globally and approximately 42 million in India. Managing the patient's pain symptoms associated with endometriosis appears to be the cornerstone in endometriosis disease management. The ideal medical treatment in endometriosis would be suppressing estradiol enough to alleviate symptoms of endometriosis but maintain sufficient levels to mitigate hypoestrogenic side effects.

Background: A normal luteal function is an essential factor for maintaining pregnancy; luteal phase deficiency decreases embryo implantation and pregnancy rate and increases the early miscarriage rate. In stimulated in vitro fertilization-embryo transfer (IVF-ET) patients, luteal phase support (LPS) is achieved by the exogenous supplementation with progesterone to increase endometrial receptivity and pregnancy. While several protocols exist, no commonly accepted protocol has been established for optimal luteal support after IVF-ET to date, the purpose of this study was to investigate the effect of two different luteal phase support protocols in patients undergoing assisted reproductive technologies.

Threatened miscarriage is defined as early vaginal bleeding before 12 weeks of gestational age and can occur in any pregnancy regardless of maternal age, race, comorbidities, lifestyle, or socioeconomic status, and about one-quarter of threatened miscarriages proceed to complete miscarriage. To assess the relative effectiveness and safety of different progestogens in women with first threatened miscarriage, using a network meta-analysis. A systematic search was conducted in PubMed, EMBASE, and Cochrane Library databases from inception to April 2023.
