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 …

IVF providers resist restricting these practices, arguing that this is counter to principles of procreative liberty, patient and professional autonomy, and free-market economics. We counter that physicians have a professional fiduciary responsibility to weigh issues of nonmaleficence to patients …

OBJECTIVE: To report the outcomes of a program policy instituted in 2004 mandating single-embryo transfer (mSET) for all women aged <38 >years, with at least seven zygotes, no prior failed fresh cycle at our center, and at least one good-quality blastocyst. DESIGN: Retrospective cohort study. SETTING: Academic medical center. PATIENT(S): All women 1, 1999, to May 31, 2004 (before mSET) and from June 1, 2004, to May 31, 2009 (after mSET). INTERVENTION(S): mSET policy implementation. MAIN OUTCOME MEASURE(S): Live-birth rate, multiple pregnancy rate, clinical volume, and outcomes of all mSET fresh IVF transfers were analyzed. RESULT(S): Clinical volume was unchanged between …
