Frozen Embryo Transfer Cycle (FETC)

Frozen Embryo Transfer Cycle (FETC)

Frozen embryo transfer (FET) also known as frozen embryo replacement (FER), consists of the thawing of embryos which were frozen during previous IVF or related treatment, and the replacing of them in the uterine cavity at the appropriate time of the menstrual cycle.

Frozen Embryo Transfer Cycle (FETC)

It is common during IVF/ICSI treatment for more embryos to be produced than are required at the time. Good quality embryos remaining after the initial embryo transfer can be successfully frozen and stored. It is important to note that about 50% of patients will have surplus embryos suitable for freezing. The initial maximum duration of storage is 10 years, although this can be extended in certain circumstances. About 85% of embryos survive the freeze/thaw process and maintain their viability. This reduces the need for repeated "fresh" IVF/ICSI cycles with their associated ovarian stimulation and egg retrieval.
