Sonographic study of the endometrial responses to ovarian hormones in patients receiving ovarian stimulation

Abstract
A total of 486 endometrial sonograms from 60 cases were reviewed to study the endometrial responses. There was a significant change in the proportion of each sonographic criterion between the pre- and post-ovulatory phases. After ovulation endometrial image showed distinct changes, and its thickness increased. These results suggest that classification of endometrial sonograms according to criteria and thickness measurements provides useful information.
