Can PFAS in your follicular fluid affect IVF success and egg quality?

What's actually in it

Women undergoing IVF (in vitro fertilization) produce follicular fluid that bathes their developing eggs. PFAS from nonstick cookware, food packaging, and water contaminate this fluid. The chemicals come in direct contact with eggs during their final stages of maturation, potentially affecting egg quality and embryo development.

What the research says

A 2026 study in Reprod Biomed Online measured endocrine-disrupting chemicals including PFAS in follicular fluid from IVF patients. The researchers found that exposure to these chemicals in follicular fluid was linked to poorer IVF outcomes, including lower egg quality and reduced embryo development.

For couples already struggling with fertility, chemical exposure in follicular fluid represents an additional barrier to successful conception.

If you're planning IVF, reduce PFAS exposure for several months beforehand by filtering water, avoiding nonstick cookware, and choosing uncoated food packaging.
