Everyday BPA Exposure Decreases Human Semen Quality

From Scientific America:

Bpa-semen-quality_1 The common industrial chemical bisphenol A (BPA) has been linked to many ills, including reproductive abnormalities, cardiovascular disease and cancer. Much of the evidence for these associations, however, has been drawn from animal or in vitro research and has been somewhat controversial as to its precise implications for human health.

Now, a human study has found strong links between BPA levels and semen quality—and the findings are not looking good, especially for men frequently exposed to the compound on the job.
Researchers studied the urine (where BPA can be measured) and semen of 218 male factory workers in China, some of whom make BPA or put it into other products (such as plastics and epoxy resins that line cans), and the remainder, whose work did not put them in direct contact with the chemical.
