The article examines how exposure to a specific air pollutant like ozone, nitrogen dioxide, carbon monoxide, and particulate matter smaller than 10 micrograms in diameter affect the semen quality. Research shows that both smoking and ozone exposure can trigger an inflammatory reaction in the male genital tract or the formation of circulating toxic species, that could cause a decline in sperm concentration. The author noted that the results of the study regarding the connection between ozone and sperm quality is consistent with other findings conducted by some other countries.
