Study: BPA changes testosterone levels in men

Studies with lab animals have shown that BPA, the chemical found in certain clear plastics, can disrupt developing endocrine and hormone systems.
A new study with humans suggests that BPA exposure also affects mature hormone systems. Researchers looking at a group of 715 Italian men, ranging in age from 20 to 74, found subtle but measurable differences in testosterone levels, with men registering higher BPA levels also showing an uptick in hormone levels.
