Brief Summary

Official Title: “Artificial Endometrial Preparation for Frozen Thawed Embryo Transfer Applying Either Endometrin or Utrogestan - a Clinical Comparative Study”

Condition Keyword(s):

The transfer of frozen-thawed embryos can be performed in a natural ovulatory cycle or in a hormonally manipulated cycle with a comparable pregnancy rate of 15%-20% per ET. When a hormonally modulated ET cycle is scheduled,an artificial endometrial preparation is carried out using estrogen stimulation followed by a concomitant progesterone treatment. Two progestative drugs are currently used in conventional IVF treatment, Utrogetan and Endometrin. Although Endometrin has been be efficiently used to support the luteal phase after embryo transfer in IVF cycles, currently, there is no study that assess its efficacy for clinical use in frozen-thawed ET cycles. The present study aims to compare the outcome of frozen thawed ET cycles when either Endometrin or Utrogestan are used as the progestative substitution in an artificially prepared endometrium.
