Can PFAS from household products affect your eggs during IVF?

What's actually in it

PFAS (per- and polyfluoroalkyl substances) enter your body through nonstick cookware, food packaging, stain-resistant upholstery, waterproof clothing, and contaminated drinking water. Once absorbed, these chemicals circulate through your blood and reach every organ, including your ovaries. They end up in the follicular fluid, the liquid that surrounds and nourishes your eggs as they develop.

What the research says

A 2026 study in Reprod Toxicol measured PFAS levels in the follicular fluid of women undergoing IVF in North Carolina. This was the first study to look for both older "legacy" PFAS and newer replacement chemicals in the same samples.

The researchers found multiple PFAS compounds in the follicular fluid, including both the legacy chemicals like PFOS and PFOA and the newer replacements that manufacturers claim are safer. The presence of these chemicals in follicular fluid means they're in direct contact with developing eggs during the most sensitive phase of maturation.

Follicular fluid provides the nutrients and signals eggs need to develop properly. Contaminating it with endocrine disruptors can interfere with egg quality, fertilization success, and early embryo development. For women already struggling with fertility, this extra chemical burden is the last thing they need.

If you're preparing for IVF, reducing PFAS exposure in the months before treatment gives your body time to clear some of the chemicals. Switch to stainless steel or cast iron cookware, avoid greasy fast-food packaging, and use a water filter that removes PFAS.
