OBJECTIVE: To compare the effectiveness of hMG and recombinant FSH after down-regulation for ovulation stimulation in assisted reproductive cycles. DESIGN: Meta-analysis. SETTING: Infertility centers providing assisted reproductive techniques. PATIENT(S): Two thousand thirty women undergoing IVF or ICSI. INTERVENTIONS: Ovarian hyperstimulation with hMG or recombinant FSH after down-regulation. MAIN OUTCOME MEASURE(S): Clinical pregnancy rate, ongoing pregnancy/live birth rate, gonadotropin dose used, oocytes retrieved, implantation rate, miscarriage rate, and multiple pregnancy rate. RESULT(S): Six randomized controlled trials were included. In all trials, the group of women treated with hMG had higher pregnancy rates. Pooling the five trials that used a long GnRH agonist protocol resulted in a higher clinical pregnancy rate for hMG compared with recombinant FSH (relative risk, 1.22 [95% CI, 1.03 to 1.44]). However, there was no evidence of a difference in rates of ongoing pregnancy or live birth per woman between hMG recipients and recombinant FSH recipients (relative risk, 1.20 [95% CI, 0.99 to 1.45]). No differences were found in gonadotropin dose used, oocytes retrieved, miscarriage rate, or multiple pregnancy rate. CONCLUSION(S): Use of hMG resulted in higher clinical pregnancy rates than did use of recombinant FSH in IVF/ICSI cycles after GnRH agonist down-regulation in a long protocol.
