Embryo freezing, also referred to as embryo cryopreservation, is the freezing of embryos for use in future. It is often performed as part of an in vitro fertilization (IVF) cycle when there are more embryos produced than can be implanted into the uterus at one time. Frozen embryos can be thawed at a later date and implanted into the uterus. These embryos are believed to have the same success rate as fresh embryos. By freezing the embryos, future cycles of IVF will take less time, as the eggs have already been retrieved and fertilized. Recommended for Patients undergoing IVF treatment Time requirements Average length of stay abroad 1 weeks. Usually embryo freezing is performed following IVF treatment. It takes several weeks for the woman's natural cycle to be suppressed, the egg stimulation, egg retrieval, egg fertilization, and embryo cultivation to take place. An embryo is formed once an egg has been fertilized. Time requirements Average length of stay abroad 1 weeks. Usually embryo freezing is performed following IVF treatment.

The embryos used for freezing are usually left over from a cycle of IVF treatment. This means that the woman has undergone hormone treatment to successfully retrieve eggs and fertilize them outside of the body, and enough embryos were created so that one or more could be implanted into the uterus and others saved for future use.,

Embryos are slowly frozen down to -196°C where they are stored in an antifreeze solution to prevent the corruption of genetic material. The embryos are later thawed in preparation for implantation. The embryos are sometimes used after the mother has given birth, and wants more children, or in cases where the first treatment is unsuccessful. Embryos are frozen using liquid nitrogen
