A team of French researchers led by Prof. René Habert has demonstrated that bisphenol A (BPA) "leads to defects in the development of the male sexual organs by inhibiting the production of testosterone." Bisphenol A "is a chemical compound that enters into the composition of plastic and resin. It is found for example in bottles, feeding bottles, drink cans and food tins.
In the light of this study, Prof. René Habert supposes that bisphenol A is one of the causes of the reduced production of sperm in adulthood as well as the rise in testicular cancers.
Since bisphenol A became suspected of producing such negative effects, the sale of feeding bottles containing this chemical compound has been banned since January 2011 in Europe. This prohibition "will be extended to all food containers from July 2015 in France."
