Twenty-two RCTs met the inclusion criteria: Fostimon(®) vs. Metrodin-HP(®) (n = 2); Fostimon(®) vs. recFSH (n = 8); and Metrodin-HP(®) vs. recFSH (n = 12). LBR (odds ratio = 1.72; 95% confidence interval = 1.05-2.80), OPR/LBR, and CPR were all significantly higher favoring Fostimon(®). OPR, MPR, OHSS, and miscarriage rates were not significantly different. Pooled results for cycle demographics were not reported due to high heterogeneity. Conclusions. Fostimon(®) is superior to Metrodin-HP(®) regarding clinical outcomes. Therefore, care should be taken not to assume that all hFSH products have the same efficacy.
