Women with higher levels of so-called “forever chemicals” in their blood have a 40% lower chance of becoming pregnant within a year of trying to conceive, according to the first known study on the effect of PFAS on female fertility.
PFAS, or per- and polyfluoroalkyl substances, have been found in almost everyone tested for them, with 99% of people in the US contaminated. The research was conducted in Singapore, where contamination levels are lower, but the scientists still found a strong correlation with reduced fertility.
