There's some research on low testosterone caused by plastic materials. I heard of doctors being able to detect plastic in a baby's blood stream. I think the reason this is not as public as it should be, is that males are sensitive when it comes to the "mannliness hormone", Testosterone. Thus, there's probably a high number of unreported cases. Some symptoms are lower sex drive and libido.
