Robust chemicals once used in everything from cosmetics to waterproofing to food containers to firefighting foam could have a significant impact on the fertility of women worldwide.
"What our study adds is that PFAS may also decrease fertility in women who are generally healthy and are naturally trying to conceive."
Each participant attended three preconception sessions over several months before receiving a series of follow-up phone calls over the following year to track their state of pregnancy. The team found a drop in fertility of around 5 to 10 percent between the lowest 25 percent of PFAS exposure and the next 25 percent, and so forth into the top quartile.
Just why this is the case is still a matter of speculation, though it's a good bet PFAS might interrupt the typical functioning of reproductive hormones in some way.
