The rapid freezing technique of vitrification is set to revolutionise egg donation as a fertility treatment by enabling freeze-storage egg-banking. The cryopreservation of eggs was one of IVF’s continuing challenges until the widespread introduction of vitrification; the older slow freezing methods induced the formation of ice crystals, which could cause damage to several structures of the egg. Thus, as demand for egg donation increases as a treatment for age-related infertility, egg banking with vitrification can theoretically provide a large pool of donor eggs without the present need for collection, fertilisation and transfer in a “fresh” treatment cycle (in which the donor and recipient’s cycles are hormonally synchronised).
