Abnormal endometrial peristalsis in frozen-thawed embryo transfer: risk factors and improvement of Atosiban treatment.

ABSTRACT:

Abstract

This retrospective study investigated factors associated with abnormal endometrial peristaltic waves (EPWs) and evaluated the impact of Atosiban intervention on clinical outcomes in frozen-thawed embryo transfer (FET) cycles. A total of 7,554 infertile women undergoing FET cycles were assessed using one-minute transvaginal ultrasound examinations 1 day before transfer to determine peristaltic frequency and direction. Logistic regression identified maternal reproductive history and cycle characteristics as parameters associated with abnormal EPWs. Among women with abnormal EPWs (n = 515), Atosiban was administered before embryo transfer, while controls (n = 7,039) did not. After propensity score matching (approximately 1:2), 505 treated cycles were compared with 993 control
