CS scar impact on ART outcomes, Retrospective Cohort Study IVF outcome can be affected by the presence of caesarean section scar with or without defect in different ways; increase difficulty of embryo transfer, presence intrauterine fluid at the time of transfer can affect the chances of embryo implantation and increase the rate of spontaneous miscarriages To compare the success rates and outcomes of pregnancies of frozen embryo transfer for euploid embryos in patients without caesarean section, and who had caesarean section (with or without a NICHE) after euploid embryo transfer. Does CS scar and CS scar defect affect IVF outcome? All women who underwent an embryo transfer with a Euploid embryo between 2015 and 2022, who meet the inclusion criteria will be included in the study.
