ObjectiveTo compare the effectiveness of highly purified hMG with recombinant FSH (rFSH) in IVF–intracytoplasmic sperm injection patients who were treated with a GnRH agonist.DesignAn open-label, prospective, randomized comparison of fixed gonadotropin regimens.SettingEighteen Dutch IVF centers.Patient(s)Six hundred twenty-nine patients who were selected for IVF–intracytoplasmic sperm injection.Intervention(s)Patients were randomized to receive either highly purified hMG or rFSH in a fixed dosage of 150 IU/d after GnRH-agonist suppression (long protocol).Main Outcome Measure(s)Ongoing pregnancy rate per started cycle. Difference between the two treatment groups was tested by using odds ratios, including the 95% confidence limits (intention-to-treat sample), and by using the Fisher's exact test (per-protocol sample).Result(s)The ongoing pregnancy rates per started cycle were 26.3% and 25.2% for highly purified hMG and rFSH, respectively (no statistically significant difference). Treatment with highly purified hMG resulted in statistically significantly fewer oocytes (n = 7.8) than did treatment with rFSH (n = 10.6). There were no differences with respect to fertilization rates and implantation rates. Cycles with highly purified hMG were statistically significantly less often canceled as a result of ovarian hyperresponse (2.0% vs. 6.0% for highly purified hMG and rFSH, respectively).Conclusion(s)Compared with rFSH, highly purified hMG did not result in superiority in ongoing pregnancy rates in first-cycle IVF–intracytoplasmic sperm injection patients who were treated with a fixed dosage of 150 IU of gonadotropin per day. Compared with rFSH, treatment with highly purified hMG resulted in retrieval of fewer oocytes, a lower incidence of hyperresponse, and comparable pregnancy rates.
