Vitrification and frozen embryo transfer (FET)

At Ovumia Fertinova Clinics, we use vitrification exclusively for freezing embryos

Vitrification is extremely well suited for all the development stages of the embryo and especially for the delicate eggs.

Vitrification is an ultra-rapid freezing process that uses protective agents to prevent the formation of damaging ice crystals and preserves the embryo in a glass-like state at a temperature of -196°C. This reduces damage caused to cells by freezing and achieves a high freeze-thaw survival rate (over 80%). Before vitrification, the fluid in the cavity of the blastocyst is reduced using a laser.

Frozen embryo transfers (FET) can be performed either during a natural menstrual cycle or a medicated cycle.
