title: Cryopreservation of mammalian ova and embryos by vitrification.
abstract: Vitrification is a new approach to oocyte and embryo cryoconservation. It consists in the solidification of a solution caused not by crystallization, but by a drastic increase in viscosity during cooling. The application of this approach to cryoconservation of oocytes and embryos of different species depends upon the development of proper procedures and non-toxic media. From the technical point of view, the vitrification method is simple and relatively easily applicable under field conditions. The authors review the current procedures applied to oocytes and embryos of laboratory and farm animals.
