China: BPA Chemical Exposure causing impotence in men

NEW YORK (AP) — Male factory workers in China who got very high doses of a chemical that's been widely used in hard plastic bottles had high rates of sexual problems, researchers reported Wednesday.

Heavy exposure to BPA, or bisphenol A, on the job was linked to impotence and lower sexual desire and satisfaction, according to the study, which adds to concerns about BPA's effects on most consumers.

The men in the study experienced BPA levels about 50 times higher than those faced by typical American men, said researcher Dr. De-Kun Li. "We don't know" whether more typical doses have similar effects, he said.

People shouldn't be alarmed by the finding, said Li, a reproductive and perinatal epidemiologist at Kaiser Permanente's research division in Oakland, California. But he said it would be prudent to limit exposure to BPA while scientists look for any effects from lower doses.

The U.S. government recently announced new funding for research into BPA's effects.
