For the first time, scientists have shown that pregnant mothers exposed to high but common levels of a widely used ingredient in cosmetics, fragrances, plastics and paints can have baby boys with smaller genitals and incomplete testicular descent.
The paper, published Friday in the journal Environmental Health Perspectives, found that the more a mother was exposed to the chemicals, called phthalates (THAL-ates), the greater the chance her boy's reproductive development would be harmed. Similar changes have led to decreased semen quality and fertility in rodents.
"We'll follow our children to see what the consequences are," says lead researcher Shanna Swan, a professor of epidemiology at the University of Rochester (N.Y.) School of Medicine.
