Premenopausal women who aren't interested in sex and are unhappy about this reality have distinctive blood flow patterns in their brains in response to explicit videos compared to women with normal sexual function, researchers report.
A study of 16 women – six with normal sexual function and 10 with clear symptoms of dysfunction – showed distinct differences in activation of brain regions involved in making and retrieving memories, and determining how attentive they are to their response to sexual stimuli, researchers report in the journal Fertility and Sterility.
Up to 20 percent of women may have this form of sexual dysfunction, called hypoactive sexual desire disorder, for which there are no proven therapies, said Dr. Michael P. Diamond, Chairman of the Department of Obstetrics and Gynecology at the Medical College of Georgia at Georgia Regents University.
