A Frozen Embryo Transfer (FET) is a cycle in which the frozen embryos from a previous fresh IVF /ICSI cycle are thawed and then transferred back into the woman's uterus. This is possible if we get many embryos in the fresh cycle. In recent years the success with Frozen Embryo Transfers (FET) has increased substantially making it a viable option to consider before moving to another fresh IVF cycle. Frozen embryos remain viable for an infinite amount of time after the initial freeze. Patients either following an unsuccessful cycle or that have successfully delivered a baby and are ready to expand their family, will have the FET treatment option waiting for them.
