Brief Summary
The worldwide prevalence of primary and secondary infertility is estimated at \~2% and 10.5%, respectively, among women aged 20-44 years and attempting to conceive. Poor ovarian responders (PORs) involve 9-24% of patients undergoing in-vitro fertilization (IVF). proper tailoring of the ovarian stimulation protocol in order to maximize the number of oocytes collected represents a crucial step for them to eventually conceive. Recent evidence indicates that in the same menstrual cycle, there are multiple follicular recruitment waves. This coincides with the theory that folliculogenesis occurs in a wave-like fashion. Thus, within a single menstrual cycle, there can theoretically be multiple opportunities for a clinician to collect oocytes, as opposed to the conventional single cohort of antral follicles during the follicular phase. Utilizing this concept, clinicians have been attempting to retrieve oocytes from poor responders using both the follicular-phase stimulation (FPS) and the luteal-phase stimulation (LPS) protocols to increase the number of oocytes collected shorter within shorter period of time. By increasing the number of the retrieved oocytes collected, a better clinical can be assured since there is a clear relationship between the number of oocytes collected and live birth rates across all female age groups. which protocol is the most effective remains controversial and the efficacy of PPOS in POR compared with that of conventional protocols is unclear.

Outcome Measures
Primary Outcomes (5)
the Number of M2 Oocytes Retrieved
it is the number of M2 oocytes retrieved that were being assessed after denudation
1-2 hours after oocyte retrieval
the Fertilization Rate
percentage transformation of micro injected oocytes into two pronuclei. it is done 16 to 20 hours after microinjection of the oocytes by the sperms
16 to 20 hours after microinjection of the oocytes with the sperms
the Resultant Embryos Number
it is the resultant embryos number counted day 3 or 4 or 5 after fertilization
the embryos number counted day 3 or 4or 5 after fertilization
the Implantation Rate
it is calculated as the number of intrauterine gestational sacs observed by transvaginal ultrasonography divided by the number of transferred embryos at the 6 th week of pregnancy and then multiplied by 100
at the 6 th week of pregnancy
the Clinical Pregnancy Rate.
percentage of cases in which observation of a gestational sac with fetal heart beat by transvaginal ultrasound at 6 weeks of pregnancy

Study Arms (2)
the progestin primed double stimulation group
ACTIVE COMPARATORluteal phase priming using combined contraceptive pills from day 21 of the previous cycle for one week by Gynera tab. Controlled ovarian hyper-stimulation with 225-375 IU of gonadotropins will be started day 2-3 of menses after vaginal ultrasound confirming the absence of ovarian cysts. Duphaston at 20 mg/day will be started from the first day of the ovulation induction.Decapeptyl in a dose of 2 ampules of 0.2 mg will be administered when leading follicle \>18 mm in diameter for triggering.Then, Controlled ovarian hyper-stimulation the next day after the previous oocyte pickup simultaneously with Duphaston. Starting from the next menstrual cycle Day 3, patients will receive oral estradiol valerate (Cyclo-Progynova (white tablets) daily.When endometrial thickness ≥ 7 mm.Embryo transfer will be scheduled on Day 3, 4 or 5 with maximum number of 3 class A embryos whether of cleavage or blastocyst stage.
the flexible GnRh antagonist
ACTIVE COMPARATORThis step will be done twice in two different cycles In each cycle: luteal phase priming using combined contraceptive pills from day 21 of the previous cycle for one week by Gynera tab. Controlled ovarian hyper-stimulation using antagonist protocol will be used. Stimulation with 225-375 IU of gonadotropins will be started day 2-3 of menses after vaginal ultrasound confirming the absence of ovarian cysts. Cetrotide ampule will be given daily as the biggest oocyte reaches size 14 mm. Decapeptyl ampules 0.2 mg will be administered when leading follicle \>18 mm in diameter. While in the second cycle HCG triggering (Choriomon)in a dose of 10,000 IU will be administered when the leading follicle \>18 mm in diameter. Embryo transfer will be scheduled on Day 3, 4 or 5 with maximum number of 3 class A embryos whether of cleavage or blastocyst stage that will be a mixture of the thawed embryos of the first cycle and fresh embryos of the second cycle.
Interventions
will be used for pituitary suppression in the first arm:20 mg/day will be started from the first day of the ovulation induction in the follicular phase and in the luteal phase will be started the next day after oocyte pickup at 20 mg/day.
will be used for controlled ovarian hyperstimulation in both arms
will used in the second arm for pituitary suppression in the second group daily when the biggest oocyte reaches size 14 mm till ovulation triggering
will be used for ovulation triggering.in the first arm:in a dose of 2 ampules of 0.2 mg will be administered when leading follicle \>18 mm in diameter. in the second arm:in a dose of 2 ampules 0.2 mg will be administered when leading follicle \>18 mm in diameter in the first cycle only.
will be used in the second cycle of the second arm for ovulation triggering in a dose of 10,000 IU when the leading follicle \>18 mm in diameter.
luteal phase priming from day 21 of the cycle before controlled ovarian stimulation for one week .
Starting from cycle Day 3 of the intented cycle for thawed embryo transfer, patients will receive the white tablets of Cyclo-Progynova daily. From Day 10 onwards, endometrium growth will be monitored by transvaginal ultrasound.
in the intended cycle of embryo transfer when endometrial thickness ≥ 7 mm. Progesterone administration (as 800 mg/day vaginal suppositories per day and 100 mg ampule IM every other day) will be continued until pregnancy testing 18 days after embryo transfer and in pregnant cases will continued till the 12 weeks of gestation.
