Untersuchungen zeigen, dass Luftverschmutzung mit DNA-Veränderungen in Spermien zusammenhängt. Studie mit mehr als 2.000 Männern identifiziert epigenetische Veränderungen im Zusammenhang mit der Exposition gegenüber häufigen Schadstoffen im Freien.

Air pollution appears to alter how sperm genes function, one of the largest fertility studies of its kind has found.
Men exposed to common air pollutants while sperm were developing showed subtle DNA changes that affected whether genes were switched on or off, raising fresh concerns air pollution may harm male fertility.

The findings, presented on Tuesday at the annual meeting of the European Society of Human Reproduction and Embryology in London, identified ozone and nitrogen dioxide as the pollutants most strongly linked to these so-called epigenetic changes.
