Indecent exposure: Male mice not quite as sexy when given chemical BPA
BPA apparently takes the butch out of male deer mice, according to a study by the University of Missouri.
Male deer mice exposed to BPA, a chemical common in our food and beverage cans since the 1960s, were less desirable to female deer mice, according to the university.
Females were far more interested in stranger males that engaged in long bouts of nose-to-nose sniffing (apparently some kind of mouse come on). Females spent more time evaluating her potential partner if it wasn't exposed.
It isn’t clear whether every girl mouse still went crazy over a sharp-dressed BPA-exposed mouse.
“The BPA-exposed deer mice in our study look normal; there is nothing obviously wrong with them. Yet, they are clearly different,” said Cheryl Rosenfeld, associate professor in biomedical sciences.
Also of note, many male mice that had been exposed to BPA early in their development never found the correct exit to a maze when tested. It is unclear whether they asked for directions like real male mice would never do.
The Food and Drug Administration has “some concern” about BPA and countries such as Japan and Canada have considered a BPA product ban. Scientist disagree about the effects in animals and humans.
