The Effect of Tamoxifen on Clinical Outcome in Women With Thin Endometrium Undergoing Frozen Thawed Cycle.

Summary

Cryopreservation of embryos created during fresh IVF cycles provides a less expensive and time-intensive opportunity for pregnancy. Ideal endometrium thickness is the key point to optimization FET cycle. Researches show that when endometrial thickness is less than 7mm, pregnancy rate dropped significantly. Tamoxifen has been reported to be oestrogenic on the lower genital tract. Several study on intrauterine insemination or ovulation induction suggest that tamoxifen may be a promising alternative for patients with thin endometrium. Based on this ,we want to evaluate the effects of tamoxifen on endometrial thickness and pregnancy outcome in women who failed to develop an adequate endometrial thickness in previous frozen embryo transfer cycle twice or even more times and willing to have another attempt.
