Description

Frozen Embryo Transfer (FET) Frozen Embryo Transfer (FET) is a process in which a previously frozen embryo (from an earlier IVF cycle) is thawed and transferred into the uterus. This allows individuals or couples to attempt pregnancy without going through another full IVF cycle. Steps of the FET Process Preparation of the Uterus The recipient takes hormonal medications (estrogen and progesterone) to prepare the uterine lining for implantation. Some patients may undergo a natural cycle FET, where the transfer is timed with their natural ovulation. Thawing the Embryo The embryo is carefully thawed before transfer. Modern freezing methods (vitrification) ensure high survival rates. Embryo Transfer The embryo is placed into the uterus using a thin catheter under ultrasound guidance. It is a quick, painless, and non-surgical procedure. Waiting Period & Pregnancy Test After about 10-14 days, a blood test (beta hCG) confirms pregnancy. Benefits of FET ✔ Higher success rates – Comparable to fresh embryo transfers due to improved freezing techniques. ✔ Less physical strain – No need for ovarian stimulation or egg retrieval. ✔ More cost-effective – Cheaper than repeating a full IVF cycle. ✔ Better embryo selection – Allows for preimplantation genetic testing (PGT) before freezing. ✔ Time flexibility – Embryos can be stored for future use. Who Benefits from FET? Couples who had extra embryos from a previous IVF cycle. Women needing time to recover before pregnancy. Patients undergoing cancer treatment that affects fertility. Those using donor embryos for conception.
