OBJECTIVE: To reduce the twin rate in our IVF program. DESIGN: A prospective educational study of infertile couples; a retrospective review of IVF outcomes before vs. after mandatory single embryo transfer (mSBT) policy change. SETTING: University-based infertility center. PATIENT(S): One hundred ten of 120 consecutive new infertile couples completed the educational study. Outcomes of all embryo transfers (n = 693) performed 17 months before and 17 months after mSBT were evaluated. INTERVENTION(S): A 1-page educational summary of comparative risks of twins vs. singletons to maternal and child health. MAIN OUTCOME MEASURE(S): Knowledge of twin risks and desired number of embryos …

OBJECTIVE: To determine the most highly expressed microRNAs (miRNAs) in human blastocysts and to compare miRNAs in euploid versus aneuploid embryos and in male versus female embryos. DESIGN: Experimental study of human embryos: 14 blastocysts (four male, five female, and five aneuploid) were evaluated for miRNA expression with the use of an array-based quantitative real-time polymerase chain reaction (qPCR). Highly expressed and differentially expressed miRNAs were confirmed with the use of qPCR in an expanded set of 27 blastocysts (seven male, eleven female, and nine aneuploid). SETTING: Academic IVF program. PATIENT(S): Thirteen couples donated 91 cryopreserved embryos for this study. …

OBJECTIVE: In addition to numerous health detriments caused by obesity, fertility and pregnancy success may also be compromised. The aims of this study were to compare the effects of obesity and morbid obesity on in vitro fertilization (IVF) outcomes. We also investigated the effects of obesity on obstetric outcomes after IVF treatment. METHODS: Retrospective study of women less than 38 years of age during their first fresh IVF cycle (January 1995 to April 2005). RESULTS: A total of 1,293 women were included in the study, with 236 obese women (body mass index [BMI] = 30-39.9) and 79 morbidly obese women …
