Frozen Embryo Transfer (FET)
Patients who have undergone IVF (in vitro fertilization) treatment may have an additional embryo (or embryos) which can be cryopreserved (frozen) and used for another attempt. This may be after the delivery of a child when the patient may wish to come back and use their frozen embryos to grow their family, or it could be after an unsuccessful stimulated in vitro fertilization (IVF). Transferring frozen embryos is a much simpler process and is less costly than undergoing an additional collection cycle. Frozen embryos maintain their cellular integrity and can give the woman more flexibility with the timing of her pregnancy.
