Chemicals in Teething Rings
Phthalates are feminizing boys
Phthalates are chemical substances that make PVC plastic soft and flexible. They are widely used in products such as food wrappings, vinyl shower curtains, and cosmetics. They are also used in soft plastic toys and other baby products, such as teething rings and rattles. Phthalates can leach out of plastic over time.
A recent study looked at phthalate levels in the urine of 85 pregnant women, then studied the genital development of their babies. The boys from the most highly exposed mothers were ten times more likely to have impaired genital development than boys from the least exposed mothers.
