This paper presents the current possibilities, state of knowledge and prospects for cryopreservation of pig oocytes and embryos. The main factors of cryopreservation efficiency, methods for the evaluation of cryopreserved embryos, and the possibilities of modifying their susceptibility to cryopreservation are discussed. In addition, the most significant results of pig embryo freezing and vitrification and the cryotechnical aspects of this method are presented.
