Frozen Embryo Transfer

What is a Frozen Embryo Transfer (FET)?

A frozen embryo transfer is a procedure where previously frozen embryos, created during an IVF cycle, are thawed and transferred into the uterus of the patient. It’s a common step for patients who have frozen embryos from a prior cycle or wish to delay pregnancy for medical or personal reasons.

How is FET different from a fresh embryo transfer?

In a fresh transfer, embryos are transferred into the uterus immediately after fertilization during the same IVF cycle. In FET, embryos are frozen and stored for future use, allowing the body to recover from hormonal stimulation or other treatments before transfer.

What is the process of a Frozen Embryo Transfer?

The FET process involves:

    - Preparing the uterine lining with medications (like estrogen and progesterone) to mimic natural ovulation.

    - Thawing the frozen embryos in a lab.

    - Transferring the thawed embryos into the uterus using a thin catheter.

The procedure is typically painless and does not require anesthesia.

What are the success rates of FET?

Success rates depend on factors like the quality of the embryos, the age of the patient at the time of freezing, and the overall health of the uterus. However, FET success rates are comparable to fresh transfers and may even be higher due to better embryo selection and uterine preparation.

 Are there risks or side effects with FET?

FET is generally safe. Rarely, a woman might have a bit of cramping or spotting. There’s also the possibility of multiple pregnancies if multiple embryos are transferred. Patients should discuss all potential risks with their doctor before the procedure.
