Slow​ ​and steady​ ​does not always​ ​win the race. ​This​ ​older​ ​technique sometimes​ ​failed to perfectly​ ​preserve eggs​ ​and prevent them​ ​from​ ​becoming crystallized. ​Only​ ​around 50%​ ​of frozen eggs were typically​ ​viable following the old freezing process.

Vitrification is a huge improvement in the egg freezing process. It essentially flash-freezes a woman’s eggs, preventing the egg from any crystallization and damage. Vitrification freezes your eggs in a glass-like state and jumps the viability rate up to 90-95%.
