In anovulatory women with polycystic ovary syndrome (PCOS), one-time use of progestin to induce withdrawal bleeding before ovulation induction may decrease the odds of conception and live birth, according to a new study conducted by researchers for the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NIHCD) Cooperative Reproductive Medicine Network (RMN).
Whether a woman is overweight or obese before and during pregnancy, and not glucose levels, is the most reliable predictor of a woman’s risk of giving birth to a large-for-gestational-age infant, according to a new study conducted in Canada.
The use of the anti-HIV drug tenofovir during pregnancy does not affect birth weight or birth length, according to new research conducted as part of the Pediatric HIV/AIDS Cohort Study.
