Air pollution linked to DNA changes in sperm, research shows. Study of more than 2,000 men identifies epigenetic changes linked to exposure to common outdoor pollutants.
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.
Without transmission rates of those methylation patterns to embryos (or even newborns), this is still very preliminary regarding its importance in population decline of sperm quality.

Correction... DNA changes in sperm linked to air pollution.
Words and grammar matter.

That is not nearly as thought provoking but does make way more sense.

Histone methylation, or Cytosine methylation?
Without transmission rates of those methylation patterns to embryos (or even newborns), this is still very preliminary regarding its importance in population decline of sperm quality.
