ObjectiveTo investigate the usefulness of day-5 inhibin B and antral follicle count (AFC) in predicting ovarian response and live birth in the first cycle of assisted reproduction.DesignProspective cohort study.SettingUniversity hospital.Patient(s)Ninety-eight infertile women treated with in vitro fertilization-intracytoplasmic sperm injection (IVF-ICSI) comprising 72 normal responders and 26 poor responders.Intervention(s)Ovarian stimulation with gonadotropin-releasing hormone agonist-gonadotropin treatment.Main Outcome Measure(s)Basal ultrasonographic (AFC, total ovarian volume) and basal (follicle-stimulating hormone, estradiol, and inhibin B) and stimulation day-5 (estradiol, inhibin B) hormone parameters.Result(s)The AFC had the best predictive value among the basal variables for outcome of ovarian stimulation. Among the dynamic hormone measurements, day-5 inhibin serum measurement emerged as the best predictive variable of poor response in IVF-ICSI cycles, but it was not statistically significantly better than basal AFC. The association of day-5 inhibin B with live-birth rate was statistically significant and stronger than the effect of any other variable investigated.Conclusion(s)Basal AFC and day-5 inhibin B have similar predictive properties for ovarian response in assisted reproduction cycles stimulated with gonadotropin after pituitary suppression, but day-5 inhibin B is a superior predictor of live birth.
