Sophisticated methods of cryopreservation of eggs, sperm and embryos offer the possibility of safe storage for future use as the retrieved reproductive cells do not age.
Cryopreservation – freezing of reproductive cells and embryos
The process of freezing of reproductive cells and embryos has become an integral part of assisted reproduction methods. It is a procedure in which reproductive cells or embryos that are not used immediately for fertilization or transfer to the uterus are frozen at temperatures down to -196 °C. This allows them to be stored for a virtually unlimited time.
