[Endometrial sonographic growth pattern in ovulatory cycles]

Ultrasonic measurements of endometrial thickness and recording of the echogenic pattern were performed daily throughout an ovulatory cycle in 20 women, aged 20-30, who had normal ovulatory cycles. There were 10 women in whom the cycle terminated in pregnancy and 10 in whom it ended in menstruation. The echogenic pattern of the endometrium was similar in both groups, but the endometrial growth pattern showed a significantly thicker endometrium (p less than 0.05) 8-13 days after ovulation in those who became pregnant.
