Abstract：Objective:To evaluate the follicular output rate (FORT) as a prognostic indicator of response to ovarian and the reproductive competence after PGD.Methods:A total of 158 PGD patients who underwent controlled ovarian stimulation using a long protocol were retrospectively studied.FORT was calculated as the ratio of preovulatory follicle count on the day of stimulation×100/small antral follicle count (3-10 mm in diameter) at baseline.Patients were divided into 2 groups:the low FORT group (79 women) and the high FORT group (79 women).The response of ovarian and IVF-ET pregnancy outcome were analyzed.Results:Among 158 PGD cycles,the numbers of retrieved oocytes and embryos available for transfer in the high FORT group were significantly higher than those in the low FORT group (P＜0.05).However,there were no significant differences in the 2PN fertility rate,good-quality embryos rate and blastocyst formation rate between two groups (P＞0.05).Conclusions:FORT can be used as a index to predict effectively the number of oocytes retrieved and the number of embryos for transfer in the PGD cycle,but it cannot predict the developmental potential of the embryo.
