Cryopreservation of eggs has remained a challenge until recently. Egg is a large cell with a high water content. The older slow freezing methods could not completely prevent the ice crystal formation which damages the cell during freezing and thawing. This has been virtually eliminated by a relatively new technique called Vitrification or ultra rapid cooling. Studies have documented comparable results with ICSI/IVF on vitrified/warmed oocytes and fresh oocytes in younger women both in terms of fertilization and clinical pregnancy. Available data on the incidence of congenital abnormalities in the children born using vitrified/warmed eggs, though limited are also reassuring with no significant increase in risk when compared with conventional IVF/ICSI and the general population. American Society for Reproductive Medicine in January 2013 lifted the label ‘experimental” from oocyte vitrification. Successful oocyte vitrification program simplifies oocyte donation programs.
