Impact of cesarean scar defect on reproductive outcomes after assisted reproductive technology
Cesarean scar defects significantly reduce live birth, clinical pregnancy, and embryo implantation rates in women undergoing assisted reproductive technology, but surgical treatments can improve these outcomes.

This paper reviews 11 retrospective studies on how a cesarean scar defect (CSD) affects reproductive outcomes after assisted reproductive technology (ART), including 8 studies from China. Across most included reports, CSD was associated with lower live birth and clinical pregnancy rates and reduced hCG positivity and embryo implantation, while miscarriage rates showed more variability (mostly higher). Several studies also found worse outcomes with larger CSD size and/or when CSD co-occurred with intrauterine fluid, but a key limitation the paper highlights is that most evidence comes from retrospective cohorts with limited prospective, multicenter, high-quality data. Relevance to endometriosis: the paper discusses “endometriosis-like” mechanisms indirectly via endometriosis-related pelvic endometriosis and adenomyosis-associated processes in the described CSD mechanisms (e.g., EMT and adenomyosis features), though the paper’s main focus is CSD and ART pregnancy outcomes.
