Vitrification is a modern cryopreservation technique based on sudden cooling of reproductive cells to a temperature of -196 ° C in seconds that produces glass-like solidification of a solution without crystallization, but by extreme elevation in viscosity during freezing

Vitrification is a modern cryopreservation technique based on sudden cooling of reproductive cells to a temperature of -196 ° C in seconds that produces glass-like solidification of a solution without crystallization, but by extreme elevation in viscosity during freezing Unlike the slow freezing method, vitrification has better results in a complete elimination of ice crystal inside the cells as well as in the surrounding solution -Also, it has a significantly higher post-thawing survival rate in comparison to slow freezing method
