Abstract
Disclosed is a method for cryopreserving an oocyte by adding an antifreeze protein to a cryopreservation liquid (equilibrium solution, vitrification solution). The disclosed cryopreservation method of an oocyte minimizes damage to the oocyte, which increases the survival rate of the oocyte after freezing and thawing of the oocyte, and improves a fertilization rate, and a blastocyst development ratio of the oocyte.
