Procedure: Embryo transfer
Procedure: Serum Estradiol and Progesterone levels
Drug: External Estradiol

Brief Summary

Traditionally, the use of GnRH-a suppression was considered essential for adequate endometrial hormonal modulation in cryopreserved-thawed embryo transfer cycles. Several studies, however, have questioned its necessity for controlled endometrial preparation. Using a high dose of estradiol from day 1 of the cycle will suppress the gonadotroph, preventing folliculogenesis and excessive secretion of LH, allowing adequate endometrial preparation without GnRH-a.

With GnRHaEmbryo transferCryopreserved-thawed embryo transfer cycle, with endometrial preparation using GnRHa followed by external estradiol and progesterone. The GnRHa depot from will be given on day 21 of the preceding cycle, on day 1 of the transfer cycle, the patient will receive 6 mg/ day of estradiol followed up on day 12 of the cycle, if the endometrium is less than 8 mm, till day 15 of the cycle estradiol will be increased to 8 mg/day until 8 mm or more. Then, serum estradiol and progesterone levels are collected, and progesterone 800 mg vaginal suppository will be added and embryo transfer performed 2 to 3 days later.
