Researchers from UCLA have discovered an apparent link between perflourinated chemicals and a delay in pregnancy during a recent study completed on Danish women.
Healthday reports that these commonly used chemicals, used in everything from pesticides to food packing, are already being phased out by the year 2010 due to other toxic effects.
The study followed a group of over 1,000 women and through blood testing, checked their levels of the chemicals perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS). Those with the highest levels of either PFOA and PFOS took the longest to become pregnant – from 60 -134% longer. UCLA researcher Dr. Jorn Olsen reported, “These widespread chemicals apparently lower the fertility in couples trying to get pregnant.”
Recently published in the Human Reproduction, Olsen’s study details that it isn’t known exactly why the chemicals delay pregnancy but one of the reasons could be their effect on hormones associated with reproduction.
Meanwhile Dr. Jamie Grifo, Director of Reproductive Endocrinology at New York University Medical Center, tells Healthday she has issues with the study. "There are probably things in the environment that are affecting us in ways we don't know about, but you have to get to the basic biology of what's the mechanism of action -- that's the missing link…the problem with the study is, it creates more anxiety and fear, but it doesn't answer the question.”
