In a case-control study, researchers measured levels of bisphenol A (BPA) in 2 sets of pregnant women—those with a diagnosis of fetal malformation and those without. Surprisingly, the women with healthy fetuses demonstrated higher rates of conjugated BPA, which may indicate that women who metabolize BPA poorly are more likely to have fetuses with developmental defects.

Another focus in preconception care and infertility evaluation needs to be placed on identifying how well a woman can adequately clear toxicant exposures.
