Tuesday, September 29, 2015This randomized, controlled trial suggests that, for women with regular ovulatory cycles undergoing frozen embryo replacement in vitro fertilization, the live birth rate is similar whether the endometrium is prepared using a natural menstrual cycle or GnRH-agonist pituitary suppression and hormone replacement therapy.
Ectopic pregnancy rate increases with the number of retrieved oocytes in autologous in vitro fertilization with non tubal infertility but not donor recipient cycles An analysis of 109140 clinical pregnancies from the Society for Assisted Reproductive Technology registry
Tuesday, September 29, 2015In autologous in vitro fertilization but not in donor/recipient in vitro fertilization cycles, ectopic pregnancy rates are higher in cycles with a higher number of oocytes retrieved.
Tuesday, September 1, 2015Using a cut point of 0.5 ng/mL, antimullerian hormone (AMH) performs well to identify patients at risk of failure of ovarian stimulation for in vitro fertilization. PicoAMH does not provide superior ability to predict failed response.
Gonadotropin releasing hormone agonist trigger in clinical in vitro fertilization Can the suboptimal candidate be defined?
Tuesday, September 1, 2015Reflections on "Risk factors for a suboptimal response to gonadotropin-releasing hormone agonist trigger during in vitro fertilization cycles" by Meyer et al.
Total levels localization patterns and proportions of sperm exhibiting phospholipase C zeta are significantly correlated with fertilization rates after intracytoplasmic sperm injection
Tuesday, September 1, 2015Total levels, localization patterns, and proportions of sperm exhibiting phospholipase C Zeta are significantly correlated with fertilization rates after intracytoplasmic sperm injection, but not after in vitro fertilization.
Metformin treatment before and during in vitro fertilization or intracytoplasmic sperm injection in women with polycystic ovary syndrome Summary of a Cochrane review
Tuesday, September 1, 2015We conducted a systematic review of the use of metformin as a cotreatment during in vitro fertilization and during intracytoplasmic sperm injection in women with polycystic ovary syndrome.

Thursday, July 30, 2015Term singletons conceived after medically assisted reproduction have an increased risk of morbidity related to birth asphyxia.
Thursday, July 30, 2015Black and Asian women undergoing in vitro fertilization have significantly lower odds of both clinical intrauterine pregnancy and live birth compared with white women.
Monday, June 29, 2015We discuss how embryo transfers in cycles without ovarian hyperstimulation are associated with lower rates of ectopic pregnancy compared with fresh autologous cycles, which suggests a difference in the uterine environment.
