Arm Label

Agonist Group (Long protocol):

Antagonist Group (Flexible protocol):

Arm Description

The 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).

The 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).

Outcomes

Primary Outcome Measures

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.

Secondary Outcome Measures

Number of oocytes retrieved:
The oocytes will be retrieved by transvaginal ultrasound-guided follicle aspiration 35±2 hours after hCG administration.
Number of Metaphase II Oocytes (MII):
The oocyte maturity will be assessed using Nikon SMZ1500 stereoscope.
Maturation Rate%:
Maturation Rate is calculated by dividing the number of mature (MII) oocytes by the number of retrieved oocytes.
Fertilization Rate%:
Fertilization Rate is calculated by dividing the number of obtained zygote (2PN) by the number of injected oocytes.
Cleavage Rate%:
Cleavage rate is calculated by dividing the number of cleavaged embryos by the number of zygotes (2PN).
Embryo Quality:
Embryos are assessed using Nikon SMZ1500 stereoscope based on ESHRE criteria (2011).
High Quality Embryos rate%:
High Quality Embryos rate is calculated by dividing the number of high quality embryos (Grade I) by the total number of cleavaged embryos.
Biochemical Pregnancy Rate% (Per Embryo Transfer):
Biochemical pregnancy is defined as a positive serum beta-hCG pregnancy test after 2 weeks of embryo transfer. The biochemical pregnancy rate is calculated by dividing the number of women who are biochemically pregnant by the number of women who have at least 1 embryo transferred.
Clinical Pregnancy Rate% (Per Embryo Transfer):
Clinical pregnancy is defined as the presence of a gestational sac on ultrasound after 3-4 weeks of embryo transfer. The clinical pregnancy rate is calculated as by dividing the number of women who are clinically pregnant divided by the number of women who have at least 1 embryo transferred.

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.
