Bisphenol-A (BPA) is found in microwave containers, baby bottles, laptops, and even canned foods. Tiny amounts circulate in the bodies of more than 90 percent of Americans.

A team of scientists says it has linked BPA to sexual dysfunction in men. BPA is a form of artificial estrogen that can disrupt your endocrine system, where hormone signals like estrogen and testosterone subtly influence the behavior of cells throughout your body.

Researchers looked at workers in four factories in China where large quantities of BPA are generated. Higher BPA exposures resulted in four times the rate of erectile dysfunction of the men who didn't work there. They also complained about ejaculation problems seven times as much, and overall, they were four times as likely to be disappointed with their sex life.
