Can endocrine disruptors found in the placenta cause physical changes visible under a microscope?
Some Concern
What's actually in it
The placenta filters nutrients and oxygen to your baby, but it also absorbs endocrine-disrupting chemicals from the mother's blood. Phthalates, bisphenols, parabens, and pesticides all pass into placental tissue. Once there, they can damage the cells that support pregnancy and fetal development.
What the research says
A 2026 pilot study in Ther Drug Monit tested human placenta samples for endocrine disruptors and examined the tissue under a microscope. The researchers found multiple EDCs in the placentas along with visible tissue damage (histopathological changes) in the affected samples.
The microscopic damage included changes in blood vessel structure and cell organization that could affect how well the placenta delivers nutrients. A damaged placenta may contribute to growth restriction, preeclampsia, and preterm birth.
During pregnancy, minimize EDC exposure by using fragrance-free products, glass food storage, and natural cleaning supplies. Every chemical you avoid means less reaching your placenta.
