Traditionally, cryopreservation of eggs, sperm, and embryos was carried out using a slow freezing process. This has changed, and today, cryopreservation of eggs and embryos is performed using the vitrification technique.
Egg vitrification allows for the ultra-rapid freezing of female gametes. Thanks to this high speed, ice crystals do not form as they did with slow freezing, which damaged the cells. Therefore, the survival rate of oocytes after vitrification is quite high.
