Freezing the embryos

Often, more than one embryo is received after IVF treatment. In such cases, the embryos can be frozen. The embryos are frozen by applying a vitrification method in our clinics. This method is also called ultra-rapid freezing. Thawed, recently frozen embryos have better survival rates, and a higher percentage of pregnancy can be achieved after transferring them to the uterus.

Vitrification is a process of freezing the embryos within several minutes. Ice crystals that can affect the embryo do not form within this process. This process is based on liquids which are used for freezing the cells and rapid solidification at low temperature. The viscosity of every liquid increases gradually. After thawing, these embryos have better survival rates.
