Abstract:

Semen cryopreservation technology is of great significance to prolong the storage time of semen of fine breed male animals, promote the development of artificial insemination technology of livestock, give full play to the breeding value of fine breed male animals, and further improve the production performance of livestock. However, due to oxidative stress caused by changes in the external environment during cryopreservation of sperm, the structure of sperm cells is damaged, and the effect of cryopreservation of semen is reduced. Therefore, the methods and evaluation indexes of semen cryopreservation were reviewed in this paper, and the components of semen cryopreservation diluent were analyzed to provide reference for the research and development of semen cryopreservation technology.

Key words: semen, cryopreservation technology, diluent
