NCT03155048

Brief Summary

In this prospective randomized trial, the parameters of the frozen-thawed embryo transfer (FET) cycles were analyzed. This study was undertaken in the Department of Assisted Reproductive Technologies and Reproductive Genetics Center at Istanbul Memorial Hospital with approval of the local ethics committee. The aim of this prospective randomized clinical trial was to compare two methods of endometrial preparation for FET, oral estradiol and estradiol transdermal patch.

Outcome Measures

Primary Outcomes (1)

  • Endometrial thickness on the day of progesterone administration

    In frozen thawed embryo transfer cycles, endometrial preparation with estrogen was performed. Estrogen was applied from the second day of menstruation cycle to 11th day of cycle. Endometrial thickness was measured by transvaginal ultrasound. If endometrial thickness was more than 7 millimeters, endometrial thickness was ready for embryo transfer on the day of progesterone administration.

Secondary Outcomes (1)
