Slow freezing and vitrification of eggs

Slow freezing and vitrification of eggs

Vitrification and slow egg freezing are two different techniques with the same purpose, to preserve female gametes for future use in in vitro fertilisation (IVF) treatment with a high guarantee of success.

However, egg vitrification is a more modern technique with greater benefits. This method, unlike slow freezing, does not generate the formation of ice crystals when going rapidly from room temperature to -196ºC. This makes the viability of the oocytes more stable. This means that the viability of the cells is not compromised.
