Is prenatal exposure to endocrine disruptors linked to birth defects?

What's actually in it

Endocrine-disrupting chemicals (EDCs) are substances that interfere with your body's hormones. Common culprits include bisphenols (used in plastics and resins) and phthalates (chemicals that make plastic soft and flexible). You can also be exposed to PFAS, which are persistent chemicals often found in coatings.

These chemicals don't just stay in the environment. They enter your body through food, water, and household products. Once inside, they can cross the placenta and affect a developing fetus during critical stages of growth.

What the research says

A 2026 study in Taiwan J Obstet Gynecol found that prenatal exposure to bisphenol A and parabens is linked to negative birth outcomes. These chemicals are not inert; they actively interact with your biological systems during pregnancy.

Research also shows that these chemicals disrupt vital functions. A 2026 study in Environ Sci Technol found that mixtures of nonpersistent endocrine-disrupting chemicals are linked to changes in angiogenic biomarkers, which are essential for healthy placental function and fetal growth.

The risks extend beyond birth. A 2026 study in Environ Int identified sex-specific associations between prenatal exposure to 15 different endocrine-disrupting chemicals and visual impairment in children by age 3. a 2026 study in J Endocr Soc linked prenatal phthalate and bisphenol exposure to an increased risk of gestational diabetes mellitus.

Even early life development is affected. A 2026 study in Environ Res highlights that prenatal exposure to PFAS is associated with changes in pubertal development and endocrine hormones in girls.
