Methods: A retrospective study was carried out in our IVF center. Those patients with normal ovarian reservation who were planned to undergo GnRH-a long protocol treatment were enrolled in this study. Totally patients were performed in H-hMG group and patients were performed in recombinant FSH (rfsh) group. The main observational outcomes included total dosage of Gn duration of ovarian stimulation the number of oocyte retrieved implantation rate clinical pregnancy rate serum estradiol (E2) level and progesterone () level on hcg injection day and cancellation rate due to ovarian hyperstimulation syndrome () risk. Results: Compared with rfsh patients in H-hMG group was older ( years vs years =0.026). Total Gn dosage was higher in H-hM group than in rfsh group. Also in H-hMG group patients need more time for total stimulation duration. On the day of hcg injection serum E2 and levels were lower in H-hMG group. The number of oocyte retrieved was less in H-hMG group but in this group patients had higher embryo available rate than that in rfsh group. H-hMG group experienced lower cancellation rate to prevent. Though higher clinical pregnancy rate showed in H-hMG group (65.3% vs 61.7%) there was no significantly statistic difference between the two groups. Conclusion: Compared with rfsh H-hMG needs higher dosage or longer duration for ovary stimulation but has lower risk higher available embryo rate and a tendency of higher clinical pregnancy rates. Key words: highly purified human menopausal gonadotrophin (H-hMG); recombinant FSH (rfsh); ovarian hyperstimulation; clinical pregnancy rate 896
