Abstract: Sperm cryopreservation can provide a simple,economical,effective way to preserve biologic genetic resources, and it has become an important means and applied in many domains such as the treatment of human infertility,livestock breeding and biodiversity conservation. Adding cryoprotectant can be effective avoiding or decreasing sperm cryodamage and chilling in the appropriate stage of sperm cryopreservation. The review contained information relating to the effect of cryoprotectant on mammalian sperm vitality in the process of sperm cryopreservation,and the topics discussed include the types of cryoprotectant,cryoprotectant selection and methods of its addition and removal.
