Programmed ovulation induction and oocyte retrieval for in vitro fertilization.
Forty-two patients underwent programmed ovulation induction for oocyte retrieval. They were treated in the preceding cycles with a progestagen, ethynodiol diacetate, at a dose of 2 mg twice daily. Two groups were defined based upon the stimulation protocol: Group A1 was stimulated with clomiphene citrate and human menopausal gonadotropin (hMG), and Group A2 with follicle-stimulating hormone (FSH) and hMG. They were compared to two randomized control groups of patients who received the same induction but were classically monitored. There was a high proportion of spontaneous ovulations in the programmed group (8/42) compared to the nonprogrammed group (0/42). There was a nonsignificant difference in the number of oocytes obtained or embryos replaced per cycle. Four pregnancies were obtained in the programmed group (24% per transfer), against 10 in the nonprogrammed patients (32% per transfer). The results of this method seem to be better using FSH for ovulation stimulation and a verification of the serum estradiol on the day of induction with human chorionic gonadotropin (hCG) and the following day (semiprogrammed method).
