Sperm Quality Declines After Exposure to Plastic Chemical BPA

Bisphenol-A, a chemical used for decades to make plastic food containers and baby bottles, was linked to lower sperm quality in men, researchers said.

A five-year study of 514 Chinese workers compared those with detectable levels of BPA in their urine, ranging from high to low, and those with undetectable amounts, according to results appearing today in the journal Fertility & Sterility. Men with measurable levels had two to four times the risk of lower sperm concentration, sperm count, vitality and motility.
