Detailed description

The goal of this randomized clinical trial is to compare the effects of two different ovarian stimulation methods: Progestin Primed Ovarian Stimulation (PPOS) vs. GnRH Antagonist in embryologic outcomes of IVF Patients. Ovarian stimulation will be conducted according to the assigned arm protocol. Both artificially prepared and modified natural cycles will be eligible to be included and the choice will be done according to the doctor's preference and the patient's menstrual cycle regularity. * For artificially prepared transfers, Estradiol Hemihydrate (Estrofem©, 2mg, Novo Nordisk, Malov/Denmark) 3x1 PO will be started on the day 2 of the menstrual cycle. After 12-14 days of usage, in order not to cancel the cycle, endometrial thickness needs measured at least 7mm and serum progesterone level \< 1.5 ng/mL. * For luteal support in addition to Progesterone (Progestan Dex©, 25mg, Kocak Farma İlaç ve Kimya Sanayi A.Ş., Istanbul, Turkiye) 2x1 SC once, with a 12-hour interval at day 14 of the menstrual cycle; Progesterone (Progestan©, 200mg, Kocak Farma İlaç ve Kimya Sanayi A.Ş., Istanbul, Turkiye) 2x1 PV will be started and continued for 5 days. Embryo transfer will be performed at 6th day. Estradiol Hemihydrate will be stopped on week 2 and progesterone support will be continued until the 8th week of gestation.
