Prenatal PFAS Exposure Linked to PMOS Risk in Daughters
A Harvard-led study of about 325 mother–daughter pairs from Project Viva found that higher PFAS levels in mothers during pregnancy were associated with daughters who later developed PMOS (the renamed PCOS) and acne, with about 2.3–2.7× higher odds. Specific chemicals such as N-EtFOSAA and PFNA were linked to PMOS and acne. While the findings add to evidence of PFAS as endocrine disruptors, the study’s small, mostly white, highly educated sample means more research is needed. Practical tips include avoiding stain guards and other high-PFAS textiles and choosing organic, home-cooked meals to reduce exposure.
