Pregnant women in the U.S. who had higher levels of a mix of six 'forever chemicals' in their bodies were less likely to develop gestational diabetes — each step up in exposure was linked to about a quarter less chance of getting it.

If people are exposed to a mix of certain 'forever chemicals' like PFOS and PFOA, they may have a harder time getting pregnant or having a baby, and the more they're exposed, the stronger this effect might be.
