Embryo Freezing
Embryo Freezing
Embryo
Cryopreservation is a procedure for freezing and storing embryos at a low temperature. Water in the embryos is replaced with a chemical solution (cryoprotectant) that prevents ice crystals from forming inside the embryos, as this would destroy them. Embryos are placed in liquid nitrogen and stored at -196°C. They may be stored this way for prolonged periods of time. When embryos are thawed, the cryoprotectant is removed and replaced with water. About 90% of good quality embryos will survive the freeze-thaw process.
