Being exposed to certain 'forever chemicals' like PFHxS, PFNA, and PFHpS doesn’t seem to affect a woman’s chances of getting pregnant or having a baby, based on current levels of exposure.

Case-Control Study
Human
2023 May 15

The study looked at three specific chemicals (PFHxS, PFNA, PFHpS) in women trying to get pregnant and found no link between them and trouble getting pregnant or having a baby.

Similar Assertions

We don't have enough solid proof to say that being exposed to certain chemicals (PFNA, PFDA, or PFHxS) affects a woman's ability to get pregnant.

If a woman is exposed to higher levels of a chemical called PFDA, it might be harder for her to get pregnant — each step up in exposure is linked to lower chances of pregnancy, and this chemical could be one of the main reasons why these types of pollutants affect fertility.

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.

If women in Singapore have more PFAS chemicals in their blood before getting pregnant, they might be a bit less likely to get pregnant each month — about 5 to 10% less with higher exposure.

Some 'safer' types of forever chemicals, like PFHpA, might make it harder for women to get pregnant each month — every higher level of these chemicals in the body is linked to an 8% lower chance of conceiving.
