Commonly Used Chemicals Found to Lower Fertility
Wash. Post/HealthDay News: Common Chemicals May Delay Pregnancy, by Steven Reinberg:
Chemicals known as perfluorinated chemicals, which are pervasive in food packaging, pesticides, clothing, upholstery, carpets and personal care products, may delay pregnancy, a new study suggests.
These chemicals are being phased out in the United States because of their toxic effects, and are expected to be completely gone by 2010. However, they remain in the environment and in the body for decades, and have been linked to developmental problems.
"These widespread chemicals apparently lower the fertility in couples trying to get pregnant," said lead researcher Dr. Jorn Olsen, chairman of the Department of Epidemiology at UCLA's School of Public Health.
Danish women in the study who had with high levels of perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS) took longer to get pregnant, Olsen said.
