The study was performed at the Hospital Lapeyronie in Montpellier, France. Timing and duration of study was not stated.
Interventions	Pulsatile GnRH VERSUS HMG for ovulation induction. IV pulsatile GnRH was started on cycle day 2 or 5 after spontaneous or induced menses, using a portable pump at 8‐20 mcg/pulse every 90 to 128 minutes. HMG was administered intramuscularly at cycle days 2 and 5 (75 or 150 IU). Based on ultrasound and E2 evaluation, doses were individualised. HMG was stopped and hCG (5,000 IU) injected when at least 1 but not more than 3 follicles >18 mm had developed.
