Abstract: Two clomiphene-human menopausal gonadotropin regimes were assessed for our in vitro fertilization and embryo replacement (IVF and ER) program since September 1983. Clomiphene, 50 mg bd, was taken from day 2 for 5 days. Human menopausal gonadotropin (hMG) was given from day 6; for the first regime, 75 IU/day was given for the first 3 days, and for the second, 150 IU/day. The subsequent dosages were dependent on the estradiol response. There were 9 cases for the first regime and 10 cases for the second. The mean number of hMG ampoules given was 16.5 and 19.25, respectively. The number of follicles seen on ultrasound was 3.0±0.5 and 3.4±1.2 (mean±SD), respectively. There was no statistical difference in the estradiol response up to the day of laparoscopic ova recovery for the two regimes. However, a spontaneous luteinizing hormone (LH) surge was observed in 4 of 9 cases in the first group and 6 of 10 cases in the second group. When a comparison was made between cases that had a spontaneous LH surge and cases that were given human chorionic gonadotropin (hCG), there was a higher estradiol level on the day of the laparoscopy in the hCG group with the lower hMG regime (P
