The pill that increases women's sex drive and decreases their appetite. It's a sex + diet pill!

Yeah, they're trying to invent it.

The Edinburgh team, led by Professor Robert Millar, have been looking at the properties Type 2 Gonadotrophin-releasing hormone.

When it was given to monkeys, they displayed mating behaviour such as tongue-flicking and eyebrow-raising to the males, while female shrews displayed their feelings via "rump presentation and tail wagging".

But the animals also ate around a third less food than they normally would.

Tongue-flicking and eyebrow-raising, eh? I look forward to the day when the world is full of skinny women who seem to be imitating Groucho Marx and William F. Buckley simultaneously. Sexy!
