Ultrasonographic appearance of the endometrium in natural and stimulated in-vitro fertilization cycles and its correlation with outcome.

Journal Article (Journal Article)

Ultrasonographic evaluation of the endometrium in 56 IVF patients was performed prospectively. Endometrial thickness and pattern were analysed in 18 natural-cycle and 38 stimulated-cycle patients. Thickness was measured from the echogenic interface of the endometrium-myometrium junction on a transverse section at the level of the fundus. Patterns were classified as A (homogeneous, hyperechogenic), B (mixed, with an outer hyperechogenic and inner hypoechogenic layer) or C (fluid-filled cavum with ring configuration). The thickness and pattern distributions were similar in natural- and stimulated-cycle patients. There was no correlation between thickness and serum oestradiol levels, the diameter of the largest follicle or the pregnancy outcome in either group. However, the occurrence of endometrial pattern A on the day prior to oocyte retrieval had a predictive value of 100% for a non-conceptional cycle. In contrast, pattern B occurred in a significantly greater proportion of pregnant than non-pregnant patients.
