The Embryologist's Impact on Blastocyst Vitrification and Thawing

"Vitrification and thawing are crucial steps in infertility treatment. Vitrification solutions are aqueous cryoprotectant solutions that undergo solidification (and not freezing) when cooled at high rates to very low temperatures, thanks to an increase in viscosity.~Thawing consists in remove the cryoprotectants, warm and dilute the blastocyst."
