Cryopreservation by control cooling rate is an expensive method only viable for specific cases such as prokaryote organisms 3-5. When an aqueous solution is rapidly cooled, crystallization is avoided resulting in water being in a metastable amorphous solid before becoming vitrified in a vitreous solid at temperatures below the glass transition.Oocyte cryopreservation is an option in hyper-stimulated patients with supernumerary oocytes. Moreover, in egg freezing, unlike embryo freezing, the genetic material is obtained from a single individual, thereby avoiding the controversy for the ownership of the embryos, in case of future separation or divorce.
