> The researchers acknowledged some limitations to their research. > For example, the data used dated from 2009 to 2010, and exposure to BPA may have decreased since, while exposure to other chemicals may have increased. > Another uncertainty is whether women of reproductive age have the same levels of chemical exposure as the men in the study. Even the researchers suggested a wider time frame and a larger comparison group.
