Endometrial thickness as a predictor of pregnancy outcomes in 10787 fresh IVF-ICSI cycles.

Abstract This retrospective study assessed the predictive value of endometrial thickness (EMT) on HCG administration day for the clinical outcome of fresh IVF and intracytoplasmic sperm injection (ICSI) cycles. A total of 8690 consecutive women undergoing 10,787 cycles over a 5-year period were included. The 5th, 50th and 95th centiles for EMT were determined as 8, 11 and 15 mm, respectively. Group analysis according to these centiles (Group 1: 11 and ≤15 mm; Group 4: > 15 mm) demonstrated significant differences ( P P P P P
