Egg vitrification

The vitrification technique for cryopreservation of eggs has the following characteristics:

• High cryoprotective concentration, but with low exposure time to avoid toxicity
• Very small medium volume for the preservation of the sample in the cryotop
• Ultrarapid cooling speed. For directly from ambient temperature to -196ºC.
• Very short procedure, although it requires a lot of experience on the part of the embryologist.

After devitrification, the egg survival rate is very high with this technique.
