摘　　要：环境是影响动物健康和经济性状的主要因素之一。近年来,养殖环境污染形势严峻,家畜暴露于严重复合环境污染物的风险不断增加,对种公畜而言,在养殖时暴露于环境污染物中,会对精子发生、精子质量等造成危害,影响家畜良种化进程和安全优质畜产品供应。然而,环境污染物导致公畜精子质量和精液品质受损的途径、分子机制及其挽救方法还不十分清楚。文章主要概述了环境污染物进入雄性生殖系统的途径,回顾了环境污染物对公畜精子质量、精液品质的影响,总结了缓解环境污染物损伤以及保护家畜精子质量的策略,以期为优化种公畜饲养管理及高效生产高品质种公畜精液提供参考。Environment is one of the main factors affecting animal health and economic traits. In recent years, the situation of aquaculture environmental pollution is serious, and the risk of livestock exposure to serious compound environmental pollutants is increasing. For male breeding stock, exposure to environmental pollutants in the breeding process will cause harm to spermatogenesis and sperm quality, and affect the breeding process of livestock and the supply of safe and high-quality livestock products. However, the pathways, molecular mechanisms and remedies of environmental pollutants that impair male sperm quality and semen quality are still unclear. This paper mainly summarized the ways of environmental pollutants entering male reproductive system, reviewed the effects of environmental pollutants on sperm quality and semen quality of male livestock, and summarized the strategies for mitigating the damage of environmental pollutants and protecting the quality of livestock sperm, in order to provide reference for the optimization of breeding management and efficient production of high-quality semen.
