Effects of BPA on E2, T, and Insulin serum levels in aged male rats. After aged rats were treated with 10–90 μg/kg BPA for 3 months, 90 μg/kg BPA significantly increased the E2 level and the estrogen to androgen ratio; BPA had the trend of decreasing the T level and increasing the insulin level. p < 0.05, compared with the vehicle controls. BPA: bisphenol A.
