What does a Frozen Embryo Transfer (FET) involve?

FET begins with hormonal preparation of the endometrium over approximately 2–3 weeks, using medications such as estrogen and progesterone to synchronize the uterine lining with the thawed embryo. Once the lining reaches optimal thickness and receptivity, a previously cryopreserved embryo is thawed in the lab and transferred into the uterine cavity via a thin catheter. The procedure itself is quick, typically painless, and performed on an outpatient basis. After transfer, you continue hormonal support for about 10–14 days until a pregnancy test is performed.
