Parabolic trend in endometrial thickness at embryo transfer in in vitro fertilization/intracytoplasmic sperm injection cases with clinical pregnancy evidence

Abstract

Sonographic measurement of endometrial thickness at embryo transfer is thought to be a good predictor of the success of in vitro fertilization/intracytoplasmic sperm injection cycles because the clinical pregnancy rate increases as the endometrium thickens. Nevertheless, a retrospective analysis of a study population of 606 patients showed a decrease of clinical pregnancy rates in the setting of extreme endometrial thicknesses.
