Abstract:
There have been some conflicting data concerning the importance of endometrial thickness and echo patterns before transfer in different IVF-ET situations under different COH regimens. We previously found in women undergoing IVF-ET after luteal phase LA-hMG a significantly higher PR in those patients attaining at least a 10-mm endometrial thickness and a lower rate in those women with an entirely homogeneous hyperechogenic endometrium (pattern C). The present study evaluated the relationship of endometrial thickness and echo pattern to PRs in donor oocyte recipient immediately before transfer. There were 16 pregnancies in 58 cycles (27.5%). Conclusions similar to the previous COH study were reached concerning the > or = 10-mm thickness levels correlating with improved PRs (9% versus 38.7%, P < 0.01). In contrast, no correlation with echo pattern was found.
