New Biological Pathway May Explain BPA Exposure, Autism Link.

A new study suggests that higher prenatal exposure to the chemical bisphenol A (BPA) is associated with a greater risk for autism spectrum disorder (ASD) in men. The researchers found that BPA can disrupt hormone-controlled male fetal brain development by silencing a key enzyme called aromatase. The study analyzed data from 1067 infants in Australia and found that boys with low aromatase activity and high prenatal BPA exposure were more likely to have autism symptoms at age 2 and a confirmed ASD diagnosis at age 9. However, further studies with larger numbers of participants are needed to confirm this link. [Extracted from the article]
