What is the Optimal Cycle Regimen for Frozen- Thawed Embryo Transfer Cycles

Infertility Clinical Trial

Official title:
What is the Optimal Cycle Regimen for Frozen- Thawed Embryo Transfer Cycles: Spontaneous Natural Cycles Versus Hormonal Replacement Treatment (HRT) Cycles

Clinical Trial Summary

Investigators will be comparing artificial (HRT) frozen-thawed embryo transfer cycles to correctly conducted spontaneous natural cycles after the transfer of a chromosomally normal embryo.

Clinical Trial Description

The most common treatment protocols for frozen embryo transfers include natural cycles with or without human chorionic gonadotrophin (HCG) trigger or endometrial preparation with hormonal treatment (artificial cycles), with or without Gonadotrophin - releasing hormone agonist suppression. Recent studies comparing artificial and natural cycles concluded that the optimal means of endometrial preparation for frozen- thawed cycle remains unclear and both options may be offered to women with regular ovulatory cycles. Correctly identified spontaneous natural cycles are the preferred option for frozen-thawed embryo transfer in women with regular menstrual cycles. Investigators will be comparing artificial (HRT) frozen-thawed embryo transfer cycles to correctly conducted spontaneous natural cycles after the transfer of a chromosomally normal embryo. ;
