Can propylparaben in personal care products affect fertility across generations?
Possibly. A 2025 study found that prenatal propylparaben exposure triggered diminished ovarian reserve that was inherited across multiple generations in mice.
What's actually in it
Propylparaben is a preservative in shampoo, lotion, deodorant, and cosmetics. It's absorbed through the skin and detected in nearly everyone's urine. It mimics estrogen and can affect reproductive development.
What the research says
A 2025 study in Nat Commun found prenatal propylparaben exposure triggered diminished ovarian reserve (fewer eggs) that was inherited across generations. Daughters and granddaughters of exposed mothers had fewer eggs, even though they were never directly exposed.
