Comparative Analysis Perinatal Complications Among Women with ART-Induced Pregnancy and Natural Conception

This matched retrospective study highlights that IVF-ET pregnancies are associated with significantly higher risks of multiple gestations and obstetric complications, independent of multifetal pregnancies. The findings underscore the necessity of optimizing embryo transfer strategies, such as promoting single embryo transfer and implementing enhanced monitoring protocols for high-risk complications in resource-limited settings like Northwest China. This study provides regional evidence to support the development of tailored ART guidelines.
