Abstract

Objective: To evaluate the pregnancy rate and pregnancy outcomes up to 12 weeks after frozen embryo transfer (FET) in women with previous cesarean section. Methods: A retrospective cross-sectional descriptive study of 115 FET cycles at the National Assisted Reproductive Technology Center from January 2023 to December 2024. Cesarean scars were classified based on the 2019 Delphi consensus. Results: The average pregnancy rate was 33.0%, with a cumulative rate of 48.7% after three FET cycles. The group with cesarean scar defect (CSD) and intrauterine fluid had the highest pregnancy rate (37.9%), followed by the group with cesarean section scar without defect (35.1%), and the lowest rate was observed in the CSD without intrauterine fluid group (24.1%) (p = 0.482). Other outcomes, including clinical pregnancy, miscarriage, and ongoing pregnancy beyond 12 weeks, showed no significant differences among the groups. Logistic regression analysis indicated a trend toward increased adverse outcomes in the group with intrauterine fluid, although this was not statistically significant. Conclusion: When residual intrauterine fluid is adequately managed, cesarean section scars do not significantly affect frozen embryo transfer outcomes. This finding supports the importance of scar assessment and individualized treatment planning in counseling patients with a history of cesarean delivery.
