The sonographic picture of endometrium in spontaneous and induced cycles.

Ultrasonic volume evaluation of the endometrium was performed on 19 spontaneously ovulating and 48 ovulation-induced women and correlated to E2 and P values in peripheral blood. No statistical correlations were obtained between either hormone level and any of the sonographically obtained parameters except for E2 levels in reference to the anteroposterior diameter of the endometrium in stimulated cycles (R = 0.29; P less than 0.05). It is concluded that the sonographic evaluation of the endometrium does not contribute to the evaluation of either spontaneous or induced cycles.
