Scientists Dressed Rats Up In Sexy Little Jackets To Find Out What Turns Them On

Maybe male rats and male humans aren't that different after all.

A team of scientists in Concordia University have done experiments which show that male rats can be conditioned to be more likely to ejaculate when female rats are wearing little jackets.

Above is an artist's reconstruction of what these rats in little jackets might look like.

The first experiment involved twelve virgin male rats undergoing fourteen "multi-ejaculation trials" with females wearing little jackets.

These males were then exposed to two sexually receptive females — one wearing a little jacket and one completely naked. A trend was observed that more males ejaculated first with the female wearing the little jacket, than the female in the buff. Imagine how excited they would be with actual little rat lingerie (artist's impression above).

A second experiment showed an even higher trend of males preferring jacket-wearing females.

This time virgin males were exposed to both sexually receptive females wearing the jackets and non-sexually receptive females not wearing jackets. These males were then exposed to two new sexually receptive females, one in a jacket and one naked, even more of these males ejaculated more with the female wearing the fetching little jacket.

When two rats want to get it on, the male will come up behind the female and grab her. This means if she is wearing a jacket the male would feel this with his whiskers.

Scientists examined the brains of the rats involved, and it was found that the males trained to find jacket-wearing females attractive showed more neural activity in the pleasure centre of the brain.

Each time my partner wears lingerie [a jacket], I'm going to have sex.

So like the rats, maybe straight human men have just been trained by their females to get horny on the slight of a lacey bra, rather than an innate love of good quality underwear.

The paper containing the study is not yet published, but the findings were presented on the November 17 at the Society for Neuroscience conference.
