Exposure to Air Pollution Linked to Greater Infertility Risk, US Study Reveals

A new study from the US reveals that exposure to common air pollutants significantly increases the risk of infertility for both men and women, The Guardian reported yesterday. Researchers examined about 1,400 individuals undergoing in vitro fertilization (IVF) to assess the impact of pollutants on egg, sperm, and embryo development.

The study identified that exposure to organic carbon and particulate matter during the development cycles was most strongly associated with negative outcomes, including reduced oocyte survival and lower fertilization rates. Contrary to prior assumptions that air pollution primarily harms women, this research emphasizes the importance of paternal exposure as well.

Lead author Audrey Gaskins from Emory University highlighted that even short-term exposures during critical reproductive windows can have lasting effects. The study also noted that air quality in IVF clinics matters, with higher organic carbon levels correlating with lower oocyte survival.

Particulate matter, produced by diesel vehicles and industrial activities, is particularly concerning, especially in areas affected by wildfire smoke. To protect themselves, individuals trying to conceive are encouraged to use HEPA filters indoors and avoid high-traffic areas during poor air quality days.
