Air pollution harms male fertility while women face similar risk from noise, study finds

Air pollution is associated with a higher infertility risk in men, while noise pollution is associated with a higher risk of infertility in women, a study has found.

The study, which has been peer-reviewed and published in the BMJ, looked at whether long-term exposure to road traffic noise and fine particulate matter (PM2.5), a particular form of air pollution, was associated with a higher risk of infertility in men and women.

They concluded: “Based on a nationwide cohort, designed to include a high proportion of people actively trying to achieve pregnancy, we found that PM2.5 was associated with a higher risk of an infertility diagnosis among men and road traffic noise was associated with a higher risk of an infertility diagnosis among women older than 35 years, and possibly among men older than 37 years.
