Several factors can explain this decline, such as smoking, chemicals and obesity. But that’s not all, pollution is frequently blamed.
Recently, a Danish study published by The BMJ (source 1) revealed that long-term exposure to air pollution by fine particles (PM2.5) is linked to a higher risk of infertility in men.

According to the results, “average PM2.5 levels higher than 2.9 µg/m3 over five years were associated with a 24% increased risk of infertility in men aged 30 to 45 years. PM2.5 was not associated with infertility in women.”

Additionally, researchers found that exposure to road noise levels 10.2 decibels higher on average for five years was associated with a 14% increased risk of infertility in women over 35. Noise was not associated with infertility in…
