No one knows what causes the defect, called hypospadias, but studies have shown that widespread chemicals called phthalates can reproduce it in rodents. Phthalates are used widely as softening agents in certain plastics, notably PVC, and are also found in some cosmetics, pharmaceuticals, and a wide range of other products." 09-08
