Toxicology of male reproduction in animals and humans.

Environmental contaminants can interfere with the male reproduction function. A review is presented of those pollutants with adverse effects on human reproduction. The possible effects of occupational and environmental exposure to various substances on male reproductive health are evaluated. This analysis considers studies showing damage of men exposed to halogenated hydrocarbons, other organic compounds, heavy metals and some physical agents, and some lifestyles, such as continuous stress, alcohol consumption, cigarette and marijuana smoking, and other addictions. Possible influences of these agents on the neuroendocrine system with the decrease of male fertility during the last decades are also discussed.
