Legal Toxins in Toys May Disrupt Male Sexual Development

The United States remains one of the few developed countries to permit the import of plastic toys made with polyvinyl chloride additives called phthalates (pronounced tha-lates), which help make toys soft and pliable enough to be twisted or sucked yet durable enough to survive a 1-year-old's grip.

...Infants, according to the Intergovernmental Forum on Chemical Safety, an affiliate of the World Health Organization, have far less capacity for detoxifying chemicals than do adults, and with toys they face all three points of a "risk triangle": "increased vulnerability" to a chemical's "toxic effects" and plenty of possibilities for exposure through "intimate contact."

Chan's bill also proposed a toy ban on Bisphenol A, but most of the scientists' attention that day was focused on a phthalate called Di(2-ethylhexyl) Phthalate, or DEHP, which when ingested can impede the production of LH, a hormone responsible for triggering cells in the testes to produce testosterone.

...Dr. Earl Gray, who has been studying the effect of endocrine-disrupting chemicals on rodents for seventeen years at the EPA's research facility in Research Triangle Park, North Carolina, told the panel that sexual malformations may follow from below-normal LH and testosterone levels.
