BPA Exposure Interferes With Ovaries in Women With PCOS

Bisphenol A (BPA) interferes with the cells that support egg development in your ovaries. For women with polycystic ovary syndrome (PCOS), this chemical could be making things worse.

What the Study Found

A 2026 study in Frontiers in Pharmacology used network toxicology and single-cell analysis to map exactly how BPA interferes with granulosa cell function. Granulosa cells surround and nourish developing eggs. When BPA disrupts them, follicle development goes wrong.

The researchers identified specific genes that BPA targets, connecting the dots between plastic chemical exposure and the reproductive dysfunction seen in PCOS. PCOS already affects 1 in 10 women of reproductive age. BPA exposure may be one reason the numbers keep climbing.

BPA Is Still Everywhere

Despite growing awareness, BPA is still in canned food linings, water bottles, food storage containers, thermal receipt paper, and dental sealants. Most people have measurable BPA in their blood and urine.

What You Can Do

Avoid canned foods with plastic linings. Never microwave plastic. Use glass or stainless steel containers. Don't handle thermal receipts more than necessary. If you have PCOS, reducing BPA exposure is one thing you can control.
