Cryo-embryo transfer / Frozen embryo transfer (CET or FET)

Cryo-conservation is a safe method of freezing and preserving embryos in special cryo-containers using liquid nitrogen at -196 ºC. This is a step taken to postpone motherhood or to preserve embryos before radiation or chemotherapy. This extremely fast freezing method, called vitrification, preserves the embryo’s tissue and they can remain frozen for as long as needed.

Cryo-conservation is followed by cryo-embryo transfer, which is the painless transfer of a heathy unfrozen embryo into the uterine cavity by an experienced physician.
