The harmful effects of bisphenol A on human male reproduction

Publié le : 22 January 2013

 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.             

The French study found that "the exposure of human foetal testicles to BPA reduces the production of testosterone, and that of another testicular hormone which is necessary for the descent of the testicles into the scrotum in the course of foetal development." The emission of testosterone by the testicle is "crucial" in the development of the foetus because "it leads to the masculinisation of the sexual organs which, in the absence of hormones, differentiate into female genital organs," explains René Habert. This reduced production during foetal development can provoke to abnormalities that require a surgical intervention after birth: hypospadias and cryptorchidism.         
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."
