| Abstract | ||||
| Background: Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic state, potentially lethal, and still one of the major complications encountered during controlled ovarian stimulation (COS) in IVF. It occurs in approximately 1–14 % of assisted reproductive technique (ART) cycles and is related to increased vascular permeability. There are two forms of (OHSS) early and late form. Objectives: The aim of the study was to evaluate the pregnancy rate from frozen thawed embryo transfer after freeze-all policy for patient with high risk for OHSS. Patients and methods: This is cohort study conducted at Genetics and Infertility Unit, Department of Obstetrics and Gynecology, Zagazig University and a private center (retro- prospective and record-based data). The study was carried out on 150 infertile cases. They were divided into three groups. Group A: Frozen thawed embryo transfer after freeze-all policy for cases of high risk to OHSS, group B: frozen thawed embryo transfer for cases with normal ovarian response and group C: Fresh embryo transfer in cycles with 6 or more oocytes with antagonist protocol. Results: The main results of the study revealed that there was high statistically significant difference between groups regarding pregnancy outcomes. Pregnancy rate in frozen cycles is better than fresh cycles in normal responders with no late OHSS and less severe early OHSS. Conclusion: Freeze-all policy improves pregnancy rate in high and normal responders. Also, it prevents late OHSS. | ||||
