外源性物质对雄性生殖系统的影响

本综述基于近期的流行病学和动物实验研究，对接触外源性物质对雄性生殖系统的影响进行探讨。雄性生殖系统的损伤主要表现为精子功能、数量和雄性生育能力的改变。研究表明，很多外源性物质主要包括杀虫剂、金属、有机溶剂和药物等会抑制精子发生过程，导致雄性不育，对雄性生殖系统产生不良影响，所以必须选择性的使用外源性物质。

Impact of Exogenous Agents on Male Reproductive Systems

This review is based primarily on tlae recent epidemiological data and animal studies conducted to explore the relationship between exposure to exogenous agents and their possible effects on male reproductive system. The evidence of pesticides, heavy metals, solvents, drugs and physical factors effects on spermatogenesis were the most prominent. Many studies had identified exposure to exogenous agents resulting in alteration of the sperm morphology and/or fertility. It is an urgent need to look at indiscriminate use of these exogenous agents.
