Embryo cryopreservation
In some cases, after performing in vitro fertilisation or intracytoplasmic sperm injection, the number of embryos obtained is higher than the number that can be transferred. When this occurs, the excess embryos are frozen and cryopreserved in an embryo bank in order to perform subsequent transfer attempts.
Cryopreservation of embryos can benefit couples who have not achieved pregnancy at the first attempt and also those who later wish to try for a second gestation.
Despite the fact that freezing embryos may reduce embryo viability to some extent, the percentage success rate using frozen embryos is similar to that of fresh embryos, currently about 40%.
