Summary

A U.S. study has found that exposure to air pollution increases infertility risks by harming egg, sperm, and embryo development.

Pollutants like organic carbon and particulate matter from vehicles, industrial facilities, and wildfire smoke negatively affect oocyte survival, fertilization, and embryo quality, as shown in the research involving 1,400 IVF participants.

Both maternal and paternal exposures were linked to fertility issues. Even air quality inside clinics affected outcomes.

Researchers recommend using air filtration systems, avoiding high-traffic areas, and staying indoors on polluted days to reduce risks.
