    National Institute of Occupational Safety and Health, Kawasaki, Japan
    J Toxicol Sci 37:565-73. 2012
    ..Plasma reproductive steroid hormone concentrations were not altered among groups in either sex. These outcomes indicate that low-dose exposure to BPA in the diet does not adversely affect reproductive development in F(1) rat offspring...

    Congenit Anom (Kyoto) 50:159-70. 2010
    ..These findings indicate that dietary exposure to bisphenol A between 0.33 and 33 ppm does not adversely affect reproduction or development as assessed in two generations of mice...
