BPA has long been blamed by environmental activists for supposedly mimicking the hormone estrogen (although scientists say its estrogenic effects are akin to eating tofu). Now researchers are trying to argue the chemical raises testosterone. A study of 715 Italian men and women aged 20 to 74 published in Environmental Health Perspectives found that men with the highest levels of BPA in their urine also had an increase in their blood testosterone concentrations — although all the hormone levels still remained within normal range.
WebMd Health News quoted ACSH’s Dr. Elizabeth Whelan on the the study results:
It is no surprise that BPA was measurable in urine, but as to BPA being causally related to an increase in testosterone, the authors note that their evidence does not prove causation. There is no reason to believe that trace environmental exposures to BPA would affect testosterone levels any more than eating a meal consisting of natural soy, which is a potential natural endocrine modulator.
