Tiny BPA Exposure Before Birth Triggers Sex-Specific Health Shifts
A rat study found that very low fetal exposure to bisphenol A causes lasting, sex-specific changes in gene expression and health: females show male-like gene patterns linked to cancer risk, while males exhibit female-like patterns tied to metabolic syndrome; immune cell changes were observed, and the results support stricter BPA regulation and align with human data on fertility and PCOS-like features.
