A recent study suggested low sex drive was simply a marketing ploy to sell more drugs. But the research team from Detroit's Wayne State University claims there is such a thing as hypoactive sexual desire disorder (HSDD) - in other words, low sex drive - after all. And they have the brain scans to prove it.
The scientists did tests on 26 women, 19 of whom had been previously diagnosed with HSDD. By showing them a series of videos, some of which contained erotic scenes, they were able to measure the women's brain activity using MRI scans.
The women who had been diagnosed with HSDD showed different brain patterns than those who had so-called normal sex drives. For instance, there are certain areas of the brain that become active when you process information about sex. In the women with HSDD, these areas remained inactive while other areas - which aren't normally associated with sexual function - were activated.
The scientists don't yet know exactly what all this means, but what they do know is that when it comes to sex, women's brains don't all work in the say way. And that's particularly relevant for those who have a low libido.
