Brief Summary
The aim of this prospective, non-randomised, open-label, clinical trial is to compare the effects of two pituitary suppression regimens; GnRH Agonist-Long Protocol and GnRH Antagonist-Flexible Protocol on clinical and embryological IVF/ICSI outcomes, and on the follicular fluid levels of Placental Growth Factor (PlGF); which is known for his pivotal role in the regulation of ovulation, embryo development, and implantation.

Outcome Measures
Primary Outcomes (1)
Follicular fluid Placental Growth Factor (PlGF) Concentrations:
Follicular fluid samples will be obtained on the day of oocyte retrieval, then they will be centrifuged to eliminate cellular elements and debris. After that, the supernatants will be frozen at -80 until assayed using an Eliza kit.
Immediately after oocyte retrieval (35±2 hours after hCG administration)
Secondary Outcomes (9)
Number of oocytes retrieved:
Immediately after oocyte retrieval (35±2 hours after hCG administration)
Number of Metaphase II Oocytes (MII):
Within two hours after oocyte retrieval
Maturation Rate%:
Within two hours after oocyte retrieval
Fertilization Rate%:
16-18 hours after microinjection
Cleavage Rate%:
Day 2 after microinjection
- +4 more secondary outcomes
Study Arms (2)
Agonist Group (Long protocol):
ACTIVE COMPARATORThe pituitary down-regulation in this group will be carried out using 0.05-0.1 mg of Triptorelin acetate subcutaneously (SC) once daily from the mid-luteal phase (day 21) of the menstrual cycle until the ovulation triggering day. When the suppressive effect is obtained, ovarian stimulation will commence with recombinant Follicle-Stimulating Hormone (r-FSH) or r-FSH + human Menopausal Gonadotropin (hMG) and the dose will be adjusted according to the ovarian response. Ovulation will be triggered by the administration of 10,000 IU of human Chorionic Gonadotropin (hCG) when at least three follicles become more than 16-17 mm. After 35±2 hours of ovulation triggering, the oocytes will be retrieved by transvaginal ultrasound-guided follicle aspiration. Then they will be prepared to undergo an Intracytoplasmic Sperm Injection (ICSI).
Antagonist Group (Flexible protocol):
EXPERIMENTALThe ovarian stimulation in this group will be started with recombinant Follicle-Stimulating Hormone (r-FSH) or r-FSH + human Menopausal Gonadotropin (hMG) on the third day of the menstrual cycle and the dose will be adjusted according to the ovarian response. Initiation of 0.25 mg of GnRH antagonist; Cetrorelix; will take place after detecting a leading follicle diameter ≥ 14 mm. GnRH antagonist administration will be continued till the day of ovulation triggering, which will be accomplished by given 10,000 IU of human Chorionic Gonadotropin (hCG) when at least three follicles become more than 16-17 mm. After 35±2 hours of ovulation triggering, the oocytes will be retrieved by transvaginal ultrasound-guided follicle aspiration. Then they will be prepared to undergo an Intracytoplasmic Sperm Injection (ICSI).
Interventions
0.05-0.1 mg subcutaneously (SC) once daily from the mid-luteal phase (day 21) of the cycle until the day of ovulation triggering.
0.25 mg subcutaneously (SC) once daily starting from the day detecting a leading follicle diameter ≥ 14 mm until the day of ovulation triggering.
Dosage adjustment according to the ovarian response.
Ovulation will be triggered by the administration of 10,000 IU of Human Chorionic Gonadotropin (hCG) when at least three follicles become more than 16-17 mm.
