New Study: Women Who Have More Sex Have More Developed Brains

There is already evidence that the brain stimulation caused by masturbation is equal in both men and women. A new scientific study published on Monday, December 27, in the journal “JNeurosci”, identified the brain region connected with female masturbation, and found that it was more developed in women who had more sex.

“We studied how the female genitals are represented in the human somatosensory cortex and whether they have any capacity for change in relation to experience or use,” co-author Christine Heim told AFP, quoted in the New York Post newspaper. , professor of clinical psychology at the University Hospital of Charite, Berlin.

The somatosensory cortex receives and processes sensory information from throughout the body. Each part of the body corresponds to a different area of ​​the cortex, forming a representative map. But, until now, the part of the map that corresponds to the female genitals has generated some debate.

The reason why the exact site was not known was due to the imprecision of the stimulation techniques. For example, during masturbation or genital stimulation by the partner, other parts of the body were also touched, which ended up stimulating other areas of the brain. This process also triggered excitement, stimulating several areas at the same time, which blurred the results.

The research involved stimulation of the clitoris of 20 women, between the ages of 18 and 45, while their brains were studied using a magnetic resonance imaging (fMRI) machine. For stimulation, a small round object was used, over the underwear at the level of the clitoris. The device was vibrated eight times, for ten seconds each time, interspersed with ten seconds of rest.

Brain-imaging results confirmed that the somatosensory cortex represented the female genitals next to the area corresponding to the hips—just as it does in men—but the exact location varies for each woman tested.

The researchers then wanted to study whether this area had different characteristics, depending on sexual activity. The 20 women were asked how often they had sex during that year, as well as since the beginning of their sex lives. “We found an association between the frequency of sexual intercourse and the thickness of the genital field,” said Christine Heim. That is, the more sex, the larger the region.

Heim had already shown, in a 2013 study, that people who suffered a traumatic experience of sexual violence had a decrease in the areas of the brain dedicated to Organs genitals. “We speculated at the time that this might be the brain’s response to limiting the perception of abuse,” he said.

The researchers clarify that the article does not answer questions like “whether having a larger area devoted to genital stimulation makes women more sensitive to touch”, for example. Nor does it tell us whether having a more developed brain region devoted to genital touching causes greater sexual desire; or if having more sex increases that brain region.

However, these results can be used for treatments aimed at people who have suffered domestic violence or who have sexual dysfunctions. The researcher hopes this research will help improve future therapies to help victims of sexual abuse.
