Climate change in the context of livestock reproduction is primarily associated with the heat stress (HS) adverse effect on livestock fertility. In females, during periods of heat, disorders of the reproductive tract occur, the placental nutrition of the fetus and its development are affected, while in males, spermatogenesis is damaged. Reproductive technologies and reproduction management are promising mitigation measures. Some other factors can also adversely affect the reproductive function in animals. The purpose of this study to show the current state of livestock reproduction, paying special attention to the problems associated with global climate change.
