The devitrification or thawing of embryos is a quick and simple process that consists of removing the straw containing the embryos from the liquid nitrogen tank and introducing it, previously uncovered, into the thawing medium at 37ºC. From this point on, it will be necessary to rehydrate the embryos and to do this, the embryos are passed through different means with decreasing concentrations of cryoprotectants.
The devitrification of the embryos is recommended to be done some time before the embryo transfer, in order to evaluate their survival.
