Experimental: GnRH agonist
Administration of GnRH agonist in alternate days, recombinant FSH and hCG microdose for ovarian stimulation.
Triptorelin (0.1 mg, Gonapeptyl® Daily; Ferring, Kiel, Germany) in alternate-days from Day 1 of the menstrual cycle until the day of hCG administration.
Other Name: Gonapeptyl
Active Comparator: GnRH antagonist
Daily administration of GnRH antagonist, recombinant FSH and hCG microdose for ovarian stimulation.
When patients presented at least two follicles ≥ 14mm upon scan on days 7- 9, GnRH antagonist (cetrorelix, 0.25 mg/day, Cetrotide®; EMD Serono, Inc, Rockland, MA, USA) administration is started and continued until hCG administration.
Other Name: Cetrotide
Inclusion criteria were as follows: women of good physical and mental health, under 37 years old, with regular menstrual cycles of 25-35 days, normal basal FSH and luteinizing hormone (LH) levels, body mass index (BMI) less than 30 kg/m2, presence of both ovaries and intact uterus, absence of polycystic ovaries, endometriosis, or gynaecological / medical disorders and a negative result in a screening for sexually transmitted diseases.
No patient had received any hormone therapy for at least 60 days preceding the study. Eligible patients who agreed to participate were randomized in two treatment groups. Patients were allocated to a GnRH analogue treatment group according to a computer-generated randomization table.
