Effect of chemical and finely-divided air pollutants on spermatogenesis and sperm parameters

Abstract

The pollutants of atmospheric air have a negative impact on the reproductive system and men fertility at different levels, adversely affects the processes spermatogenesis and semen parameters, has gametotoxic and genotoxic effects. The review considers the effects of fine particles, various gases (nitrogen dioxide and oxide, carbon monoxide, sulfur dioxide, ozone), heavy metals (lead, cadmium) and polycyclic aromatic hydrocarbons on male reproductive system, quantity of sperm, mobility, morphology, number of sperm and fragmentation of sperm DNA. The studies about the influence of air pollution on male reproductive system on laboratory animal models are analyzed.
