Air pollution may increase infertility risks for men, while traffic noise poses a similar risk for women over 35, according to a study.
Tobi Thomas reports for The Guardian.
In short:
- Fine particulate matter (PM2.5) raises infertility risk in men by 24% when exposure is higher than average.
- Women over 35 face a 14% increased risk of infertility when exposed to elevated road traffic noise.
- Men over 37 may also have a small risk of infertility linked to noise exposure.
Key quote:
"As many western countries are facing declining birthrates and increasing maternal age at the birth of a first child, knowledge on environmental pollutants affecting fertility is crucial."
— Researchers from the BMJ study
Why this matters:
Rising infertility rates could be influenced by environmental pollutants, affecting birthrates in many Western countries. Reducing air and noise pollution could help address fertility challenges.
