[PM2.5 exposure-caused damage to male reproductive function: Progress in research].

Particulate matter 2.5 (PM2.5) is considered to be a major harmful constitutent of air pollution. Animal experiments and epidemiological studies at home and abroad have shown that exposure to PM2.5 causes damage to male reproductive function in addition to direct impacts on the respiratory and cardiovascular systems. This review summarizes the results of animal experiments at home and abroad and population epidemiological investigations relating PM2.5-induced damage to male reproductive function as well as the mechanisms of PM2.5 causing the damage.

[Impacts of Bisphenol A exposure on spermatogenesis in men: Advances in studies].

Bisphenol A (BPA), a common endocrine disrupting chemical, is becoming a focus of studies and receiving increasing attention. Because of its wide use in food packaging materials, receipt paper, dental sealant and other products, people contact it through the skin, respiratory tract, digestive system and other routes. A large number of studies at home and abroad have shown that BPA exposure can adversely affect male reproductive function, including semen quality, spermatogenesis, sperm epigenetic inheritance, etc. Its action mechanisms, however, remain unclear and require more studies. This review focuses on the impacts of BPA exposure on spermatogenesis in males.
