Sexology: Porn shrinks the brain

Porn or brain, you have to choose. According to work by researchers from the very serious Max Plank Institute for Human Development in Berlin, men who spend a lot of time watching pornography on the Internet, at least 4 hours a week, seem to have less gray matter in certain parts of the brain. and reduced brain activity.

In their study, the researchers found a significant negative link between watching pornography for several hours per week and the volume of gray matter in the right lobe of the brain, as well as with the activity of the prefrontal cortex.

These effects could indicate changes in neuronal plasticity resulting from intense stimulation of the pleasure center, they said in this study published online in the prestigious Journal of the American Medical Association (JAMA).

However, the authors cannot prove that these phenomena are caused by heavy consumption of pornography and believe that more research is therefore necessary. But they say the work provides the first indication of a link between viewing pornography and a reduction in brain size and activity in response to sexual stimulation.

Pornography: 4 hours a week and the brain shrinks

For this study, the authors, including Simone Kühn, recruited 64 healthy men between the ages of 21 and 45 and asked them to answer a questionnaire on the time spent watching pornographic videos, which averaged four hours. per week.

They also did a scan (MRI) of their brain to measure its volume and see how it reacted to pornographic images. They found that the more pornography the subjects watched, the smaller the size of the striatum, a small nerve structure just below the cerebral cortex.

Pornography: an addiction to images

The scientists also observed that the higher the consumption of pornographic images, the more the connections between the striatum and the prefrontal cortex, the outer layer of the brain linked to behavior and decision-making, deteriorated.

Individuals with smaller striatum volume may need more external stimulation to enjoy. They would thus seek more pleasure in the sight of pornographic films, which could also lead to consuming more and more of them, creating a kind of addiction, concludes the study.
