27 Feb 1997: Common Chemical Shows Estrogen-Like Action

Bisphenol A, a chemical used in some plastic products, shows estrogen-like activity in mice and can pass from pregnant mice to their offspring, the males of which have enlarged prostates as adults, University of Missouri-Columbia scientists report in the current Environmental Health Perspectives, the journal of the National Institute of Environmental Health Sciences. Whether bisphenol A leaches from the plastics to an extent that might pose a risk to humans is in dispute. Additional research is planned.

 

The UM-C scientists said the chemical's estrogen-like effect "appears at much lower doses than previously thought" and ";lies within the range of current human exposure."

 

The researchers -- Susan C. Nagel, Frederick S. vom Saal, Kristina A. Thayer, Minati G. Dhar, Mike Boechler and Wade V. Welshons -- reported that they introduced bisphenol A in pregnant mice at a time when the prostate is developing in the fetus and that subsequently the male offsprings' prostates were found to be enlarged at adulthood.
