Risks of Egg, Embryo & Sperm Freezing

What are the Risks of Egg, Embryo, and Sperm Freezing with Vitrification?

Compared to the slow freezing method, vitrification is a more reliable freezing method giving much higher survival rates. However, it’s important to note that not every frozen egg or frozen embryo will survive the warming process. Also, not all thawed eggs will fertilize nor will every thawed embryo continue to develop.

There have also been concerns if the levels of cryoprotectants used in vitrification may affect the frozen cells. But with the ability to deselect abnormal embryos through genetic screening for genetic mutations and chromosomal abnormalities has the potential to improve live birth rates.
