Exposure to high levels of a controversial chemical found in thousands of everyday plastic products appears to cause erectile dysfunction and other sexual problems in men, according to a new study published Wednesday.

The study, funded by the federal government and published in the journal Human Reproduction, is the first to examine the impact of bisphenol A, or BPA, on the reproductive systems of human males. Previous studies have involved mice or rats.

The research comes as government agencies debate the safety of BPA, a compound that is found in thousands of consumer products ranging from dental sealants to canned food linings and that is so ubiquitous it has been detected in the urine of 93 percent of the U.S. population.

Researchers focused on 634 male workers at four factories in China who were exposed to elevated levels of BPA. They followed the men over five years and compared their sexual health with that of male workers in other Chinese factories where BPA was not present.
