Day-5 inhibin B serum concentrations and antral follicle count as predictors of ovarian response and live birth in assisted reproduction cycles stimulated with gonadotropin after pituitary suppression.
Fertility and Sterility(2010)
Abstract
To 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.Prospective cohort study.University hospital.Ninety-eight infertile women treated with in vitro fertilization-intracytoplasmic sperm injection (IVF-ICSI) comprising 72 normal responders and 26 poor responders.Ovarian stimulation with gonadotropin-releasing hormone agonist-gonadotropin treatment.Basal ultrasonographic (AFC, total ovarian volume) and basal (follicle-stimulating hormone, estradiol, and inhibin B) and stimulation day-5 (estradiol, inhibin B) hormone parameters.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.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.
