Cryopreservation of impregnated egg cells and embryos

Cryopreservation allows a couple's excess impregnated egg cells and embryos to be frozen during in vitro fertilisation (IVF) treatments. The egg cells previously collected under general anaesthesia with ultrasound control in the operating theatre are isolated from the follicular fluid and then fertilised in the laboratory using traditional IVF techniques or ICSI (intracytoplasmic injection of a spermatozoid). The impregnated egg cells and embryos are then frozen and stored in liquid nitrogen at -196°C.
