New Research Shows Link
Between Sperm and Air Quality
|
Where a man lives and works may affect his ability to conceive a child, according to a three-year study conducted by researchers at the Keck School of Medicine at the University of Southern California.
The researchers analyzed sperm samples from 50 men living in Los Angeles and compared them to air pollution measurements from the zip code where each man resided. They found that as ozone levels increased, sperm counts dropped.
This study supports similar findings conducted by scientists from the U.S. Environmental Protection Agency in the Czech Republic. It found that men exposed to high levels of air pollution were more likely to have poor quality sperm compared to those who lived in areas with less air pollution.
