WOMEN who have a low sex drive could now have a scientific explanation for their lack of desire after US experts found their brains behave differently to other females.No word whether they were plied with alcohol.
Those with a low libido have distinct patterns of brain activity compared to those with a healthy sex drive, according to a study by Wayne State University in Detroit, suggesting that a long-term lack of interest in sex is not just all in the mind.
Certain areas of the brain that normally light up when processing information about sex fail to do so in women with a condition known as hypoactive sexual desire disorder (HSDD), doctors said.
Dr Michael Diamond said that his study offered “significant evidence” that the controversial condition does exist as a physiological disorder, rather than being purely psychological.
The latest study involved 19 pre-menopausal women with clinically-diagnosed HSDD and seven women with normal sexual function.
They were asked to watch television for half an hour, during which time a blank blue screen, everyday shows and erotic videos were alternated every minute.
At the same time, magnetic resonance imaging (MRI) scans showed differences in how the women’s brains reacted to sexual stimuli, with particular changes seen in regions known to play a role in emotional or sensory processing.
Dr Diamond, who was due to present the latest study to the American Society of Reproductive Medicine annual meeting in Denver, Colorado, said: “The study indicates that there are some similarities between women with normal sexual function and those with HSDD, but that there are certain areas of the brain that have different characteristics."
Dr. Melissa Clouthier has some thoughts.
