Could BPA Be the Reason Why Many Women are Infertile?
January 03, 2011
Bisphenol A (BPA), which is a chemical used to harden plastic and line food containers, may be harming women's eggs.
Evidence links exposure to the chemical to a lower quality among eggs retrieved for in vitro fertilization. A study found that as blood levels of BPA in the women studied doubled, the percentage of eggs fertilized normally declined by 50 percent.
"The researchers noted BPA -- found in the urine of nearly everyone tested in a 2004 U.S. analysis -- is an endocrine disruptor that either mimics or blocks body hormones."
