During the IVF process, usually many embryos are produced. Sometimes we need to test the embryo’s genetics before a transfer, so we provide embryo freezing to preserve the embryos for future use. Recent SART and CDC reports indicate that the pregnancy success rate of transferred frozen embryos is comparable to that of fresh embryos and even better with genetic testing. Of course, success rates depend on many factors, such as: mother’s age, embryo quality, and cause of infertility.
Currently, our embryo freezing method is vitrification. The way to perform vitrification is to add cryoprotectants (ethylene glycol, DMSO, glycerol, propanediol, etc.) to the embryo culture media. Cryoprotectants can help avoid ice crystal formation during the freezing process. Once the embryos are vitrified, they are stored in liquid nitrogen, where the embryos are securely stored and remain
indefinitely. The success thaw rates for vitrified embryos are very high compared to
previously used methods of cryofreezing.
