Study: BPA Linked to Higher Testosterone Levels Small Increase
in Testosterone Levels in Men's Blood After Exposure to Plastic
Chemical Aug. 26, 2010 -- Men who are exposed to high levels of
the controversial plastic chemical bisphenol A (BPA) may show a
small, but significant increase in blood levels of the male sex
hormone testosterone, a study shows. These testosterone levels
still remained within the normal range. The study is published
in Environmental Health Perspectives. Some preliminary research
has linked elevated testosterone to an increased risk for heart
disease and certain cancers, but whether BPA significantly
affects testosterone and whether this has any effect on health
remains unproven. BPA is an ingredient found in the liners of
some food cans, feeding cups, and baby bottles. Growing numbers
of companies now offer BPA-free bottles. Citing "potential
health concerns," the FDA has called for more study on BPA. In
the CHIANTI Adult population study, researchers measured BPA
levels in the urine
