GENETICISTS, however, say human and mouse eggs go through almost identical processes of maturation. "Everything we know about how human and mouse eggs are regulated and prepared for fertilization [indicates that these processes are] essentially the same," says John Eppig, senior staff scientist at the Jackson Laboratory, a mammalian genetic research facility in Bar Harbor, Maine. Hunt's work does not prove that BPA causes aberrations in human eggs, but it should make people cautious about how they use polycarbonate plastic, Eppig says. In his lab, researchers study oocyte (egg) development in culture. To avoid exposing the eggs to BPA, they collect water that will be used in the experiments from a spring, distill it with glass equipment, and store it in glass bottles. The plastics council next claims: "The potential for BPA to cause reproductive or developmental effects has been comprehensively examined in two studies. In these studies, BPA did not cause reproductive or developmental effects at any environmentally relevant dose. The weight of scientific evidence provided by these studies, as well as others that have looked specifically at reproductive or developmental effects, clearly supports the safety of BPA." |
