Vitrification:

The name comes from 'turning to glass', and was developed in 1999. Recent studies suggest that the survival rates of eggs and embryos frozen via this method are increased. That said, there is no significant increase in the pregnancy rate. This freezing method is faster, using much higher levels of cryoprotectant and a very fast cooling rate by plunging the eggs / embryos into liquid nitrogen at -196°C. So no ice crystals can form and as a result the solution remains clear. Samples are kept at -196°C.

Each technique offers different benefits depending on the stage of the oocytes or embryo development. Our Embryologists will use the most appropriate method for you.
