Objective To compare the differences in clinical outcomes of ovulation induction with highly purified human menopausal gonadotropin(HP-hMG,Menopur)versus recombinant human follicle stimulating hormone(rFSH,Gonal-F)in normal ovarian responder patients treated with the GnRH-antagonist protocol.Methods Pa-tients treated with the GnRH-antagonist protocol were retrospectively analyzed and divided by gonadotropin(Gn)usage into HP-hMG group and rFSH group.The basic characteristics,ovulation induction method,laboratory inde-xes,and clinical outcomes were compared between the two groups.Results A total of 614 normal ovarian re-sponder patients were enrolled in the study,with 216 in the HP-hMG group and 398 in the rFSH group.There was no significant difference in P levels and LH levels on the hCG trigger day between the two groups.However,the E2 levels on the hCG trigger day were significantly lower in the HP-hMG group(P＜0.001).Moreover,the HP-hMG group had a higher biochemical pregnancy rate(69.23％vs 63.51％)and clinical pregnancy rate(66.67％vs 59.46％)compared to the rFSH group.The incidence of OHSS in the HP-hMG group(2.31％vs 3.02％)showed a decreasing trend compared to the rFSH group.Conclusion Compared to rFSH,HP-hMG offers distinct advanta-ges in reducing the incidence of OHSS and improving pregnancy outcomes in normal ovarian responder patients un-dergoing pituitary suppression with the GnRH-antagonist protocol.
