Abstract
OBJECTIVE: To evaluate trends in diminished ovarian reserve (DOR) assignment in the Society for Assisted Reproductive Technology (SART) Clinic Outcomes Reporting System database and to evaluate its accuracy in predicting poor ovarian response (POR) as defined in European Society of Human Reproduction and Embryology's Bologna criteria (2011). DESIGN: Retrospective cohort study. SETTING: Not applicable. PATIENT(S): A total of 181,536 fresh, autologous ART cycles reported to SART by U.S. clinics in 2004 and 2011 (earliest and most recent available reporting years). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): DOR assignment was the primary exposure. POR, defined as cycle cancellation for poor response or less than 4 oocytes retrieved after conventional gonadotropin stimulation (>149 IU FSH daily), was the primary outcome. Secondary outcomes were live birth and number of oocytes retrieved. DOR prevalence, power of DOR and FSH (
