The Claim

In adult male mice exposed to 20 mg/kg of bisphenol A via intraperitoneal injection for 7 days, testicular and serum testosterone levels are significantly reduced, free cholesterol levels in testicular tissue are decreased, and lipid droplet accumulation in testicular tissue is reduced, indicating that bisphenol A disrupts testosterone synthesis by limiting cholesterol availability in Leydig cells.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Exposing adult male mice to 20 mg/kg of bisphenol A for 7 days reduces testosterone levels in the testes and blood, decreases free cholesterol in testicular tissue, and reduces lipid droplet accumulation in the testes.

See the scientific wording

In adult male mice exposed to 20 mg/kg of bisphenol A (BPA) via intraperitoneal injection for 7 days, testicular and serum testosterone levels are significantly reduced, accompanied by decreased free cholesterol and lipid droplet accumulation in testicular tissue, suggesting that BPA disrupts testosterone synthesis by limiting cholesterol availability in Leydig cells.

Why this might work

Bisphenol A causes Leydig cells in the testes to produce more apolipoprotein A1, which grabs cholesterol and ships it out of the cells as part of HDL particles. This removes the cholesterol that testosterone needs to be made, so testosterone production drops.

  1. Study: Bisphenol A attenuates testosterone synthesis via increasing apolipoprotein A1-mediated reverse cholesterol transport in mice

    In mice given a high dose of BPA for a week, their testicles made less testosterone because the chemical made their cells push out too much cholesterol, which is the raw material needed to make testosterone.
