Frozen embryos are commonly used during in vitro fertilization, IVF, treatment. Frozen embryos may be used for a variety of reasons. For some, fresh embryo transfers cannot be done due to the effects of fertility medication. For others, surplus embryos were stored from previous IVF cycles. It’s common to have questions about frozen embryo transfer success rates and how freezing embryos works.
Thanks to advances in technology, embryos today are frozen using vitrification. Prior to the introduction of vitrification, embryos were frozen using a slow dunk method. Because the embryos were gradually cooled to their storage temperature, ice crystals were able to form which could severely damage eggs. Vitrification instantly freezes eggs and therefore does not set the stage for ice crystal formation.
When vitrification is used, embryos have a survival rate for the freezing and thawing process of 98 percent.
Frozen Embryo Transfer
When frozen embryo transfer is done the cycle can be done in a way to create the best possible environment for the transferred embryo. Medication can be prescribed, when needed, in order to enhance the uterine lining in order to increase the chance of implantation. The storage process does not harm the embryos, so frozen embryos are just as healthy as their fresh counterparts.
Prior to transfer, frozen embryos are thawed in a state of the art facility and their quality is verified.
