New research conducted by scientists suggests that there could be a physical reason why some women have persistently low sex drives or libidos. The difference in the way that the brain functioned was seen to be responsible for this, found the study.
According to the study conducted by the Wayne State University in Detroit and presented to the American Society for Reproductive Medicine conference in Denver, women who have lower sex drives mentally process certain things differently.
Previously this phenomenon has been studied and is generally referred to as Hypoactive Sexual Desire Disorder in women; which this study now suggests has a genuine physical cause.
In the study, erotic videos were used to assess the reactions of women who were diagnosed with Hypoactive Sexual Desire Disorder. Their brain responses to the videos were measured on a functional magnetic resonance imaging scanner to observe and measure their reactions.
Women who did not have the disorder displayed increased activity in the part of the brain connected to processing emotion or the insular cortices. Women diagnosed with the disorder did not display the same activity. This goes against the belief that such disorders have a social origin or that they are not really a disorder at all.
