Exposure to air pollution has been found to have a significant impact on male fertility. A recent study, presented at the European Society of Human Reproduction and Embryology meeting in London, tracked 1,220 men in Utah over four years and found that exposure to common air pollutants during sperm development is linked to subtle DNA changes that can affect gene activity. These changes can affect fertility, adding to concerns about air pollution's impact on reproductive health.
Professor Richard Lee, a reproductive biology expert at the University of Nottingham, explained that the study found that ozone and nitrogen dioxide showed the strongest associations with DNA changes. He also highlighted the importance of understanding the mechanisms behind these changes, which can have long-term consequences for fertility.
Professor Lee emphasized that the best way to stay healthy is to lead a healthy lifestyle, which includes avoiding exposures to excess amounts of pollutants. He also suggested that face masks and trips out of the city can help reduce exposure to pollutants, but noted that these are not foolproof solutions and that more research is needed to fully understand the impact of air pollution on fertility.
