Study suggests exposure to ‘forever chemicals’ may be a main driver of disease, formerly called PCOS, authors say

New research for the first time links prenatal exposure to Pfas “forever chemicals” with the development of polyendocrine metabolic ovarian syndrome (PMOS) later in life.

PMOS, formerly known as polycystic ovary syndrome (PCOS), is estimated to impact about 13% of women. Many cases are undiagnosed, and the disease’s cause largely remains a mystery.

The new peer-reviewed study, led by Harvard University, looked at about 325 mother-daughter pairs and found that mothers with higher Pfas levels in their blood during pregnancy were more likely to have a daughter with PMOS and moderate-to-severe acne by their later teenage years.
