Conventional Technologies for Cryopreservation of Human Oocytes and Embryos

In the last few years, there has been a significant resurgence of interest in the potential benefits of human oocyte freezing. Essentially, these benefits are formation of donor “egg banks” to facilitate and lessen the cost of oocyte donation for women unable to produce their own oocytes; provision of egg cryostorage for women who wish to delay their reproductive choices; and convenient cryopreservation of ovarian tissue from women about to undergo therapy deleterious to such tissue, which may threaten their reproductive health.
