Medicated FET Cycle

Meaning

A Medicated Frozen Embryo Transfer (FET) Cycle is a standardized clinical protocol in assisted reproductive technology where a patient’s natural menstrual cycle is suppressed and controlled entirely by exogenous hormonal medications. This approach involves administering estrogen to build the endometrial lining, followed by progesterone to induce the secretory phase and open the implantation window. This tightly controlled, non-natural cycle allows for precise timing of the frozen embryo thaw and transfer, making it a highly predictable and widely used method for patients with irregular cycles or those using donor eggs. The regimen is designed to create an optimal, receptive uterine environment.
