Animal Findings Suggest That Gender May Also Influence Chemical Exposure Risks for Humans
COLUMBIA, Mo. — Parents, teachers and psychologists know boys and girls behave differently. However, that difference isn’t taken into account by most methods used to assess the risk to children from chemical exposure, according to Cheryl Rosenfeld, associate professor of biomedical sciences in the University of Missouri’s Bond Life Sciences Center. A series of experiments by Rosenfeld studied the effects of prenatal exposure to bisphenol A (BPA) on later reproductive-associated behaviors using a socially and genetically monogamous rodent, the California mouse, which may better mirror most human societies than other rodents.
