Smoggy Air May Spawn Weaker Sperm

A recent study conducted by scientists in China indicates that poor air quality might have a damaging effect on male fertility.

Although the direct methods by which air pollutants reduce fertility remains unclear, scientists believe that the harmful particles are those that are known as particulate matter.

Although scientists caution that the actual impact is relatively small, they also warn that, because pollution is so widespread and a worldwide problem, the results could end up being significant.

Other researchers, located in the United States, have countered that the impact on sperm only occurs in places with especially extreme levels of pollution. Scientists agree that it is too early to conclude with certainty whether a causal relationship exists or not, but the latest findings suggest that further exploration and research will be necessary.

Key Takeaways:

• The authors of the study stress that it is too soon to determine a causal relationship one way or the other
• United States based scientists have conducted similar studies, which have lead them to believe sperm is only impacted in locations with unusually extreme levels of pollution
• The researchers behind the Chinese study suggest that although the impact of air pollutants on infertility may seem small, the widespread and worldwide nature of pollution could mean a larger effect

“Men who have trouble conceiving may have the air they breathe to blame, a new study by Chinese researchers suggests.”
