About this study

One of the barriers in patients with diminished ovarian reserve (DOR) is the significantly reduced number of oocytes resulting in fewer oocytes collected and embryos formed. Many ovarian stimulation strategies have been proposed to improve oocyte or embryo quantity which is oocyte accumulation could be a potential option with a comparable success rate and reasonable cost. Progestin-primed ovarian stimulation (PPOS) protocol could be suggested as an alternative method of premature Luteinizing hormone (LH) prevention in IVF. It favors segment Assisted Reproductive Technology (ART) cycles such as frozen embryo transfer (FET), oocyte donor, fertility preservation, and oocyte accumulation set. The protocol is more patient-friendly and affordable than the GnRH antagonist regimen regarding LH suppression during ovarian stimulation. Many PPOS protocols have been proposed in which the three most common agents include Dydrogesterone (DYG), Micronised Progesterone (MIP), and Medroxyprogesterone acetate (MPA). Indeed, DYG seems to have some advantages, including oral administration and safety which has been used in the treatment of threatened abortion. Initial evidence of PPOS protocol suggests that oocyte quantity and quality are comparable with other ovarian stimulation regimens. However, data related to the PPOS protocol has not been well documented, including Dydrogesteron-primed ovarian stimulation (DPOS). There has not been an RCT with a large sample size and well-designed to pr…
