A gender-bending chemical found in food packaging may reduce a man's ability to attract a female, researchers warn.
A study from the University of Missouri found male mice who were exposed to bisphenol A as babies became demasculanised and 'behaved more like females.' Study author associate professor Cheryl Rosenfeld, said the chemical had suppressed the early production of testosterone, which the females could sense.
'The BPA-exposed deer mice in our study look normal; there is nothing obviously wrong with them. Yet, they are clearly different,' she said.
