The outcomes measurements
Menstruation
SECONDARY
Single-layer endometrial thickness on the 20th day of menstruation was measured by ultrasound before and after operation. The pre- and post-operative endometrial thickness and the amount of endometrial growth in the two groups were compared. The changes in the pattern and amount of menstruation before and after surgery in both groups were also compared. Since serum E2 levels were related to hormone treatment effect, the E2 level before and 5 days after the operation was tested and compared. The first- and second-look AFS scores were compared to assess endometrium rehabilitation. Menstruation and postoperative endometrial thickness are the primary outcomes, and pregnancy rate is the secondary outcome of our study. Pregnancy information was actively collected during 1-year follow-up after the operation.
