Abstract

Progestin-primed ovarian stimulation (PPOS) regimen was established for assisted reproduction. However, its feasibility and outcomes in polycystic ovary syndrome (PCOS) patients need further evaluation. The outcomes of infertile patients with PCOS (study group) and normal ovaries (control group with unexplained infertility and tubal factor infertility) who underwent PPOS and IVF/ICSI protocol were retrospectively studied. The baseline information, primary, and secondary outcomes of patients were collected. The dynamic changes of hormones were closely monitored. 198 PCOS patients and 374 controls were included in this study. After controlled ovarian hyperstimulation (COH), 15 oocytes were retrieved from PCOS patients on average, which was more than those from the controls (p < 0.001). The oocytes and embryos obtained from the PCOS patients exhibited better developmental potential as the number of fertilized oocytes, cleaved embryos, top-quality embryos, viable embryos, cryopreserved embryos, the rate of fertilization, and viable embryo per oocyte retrieved in PCOS patients were significantly higher than those in the controls (all p < 0.001). No significant difference between the two groups was identified regarding the primary outcome, ongoing pregnancy, and other secondary outcomes. No moderate to severe ovarian hyperstimulation syndrome (OHSS) was diagnosed in either group. With the proposed PPOS protocol, the quantity, quality, developmental potential of oocytes, and embryos obtained from PCOS patients were superior to those from controls. The protocol was efficient and safe in terms of pregnancy, obstetric, and perinatal outcomes. OHSS was effectively mitigated in the patients, with or without PCOS, who underwent COH.
