Brain Studies on Porn Users

Max Planck Institute logoRecent studies assessing brain structure & functioning of porn users:

  1. Brain Structure and Functional Connectivity Associated With Pornography Consumption: The Brain on Porn (2014) - A German study which found 3 significant addiction-related brain changes that correlated with the amount of porn consumed. It also found that the more porn consumed the less activity in the reward circuit, indicating desensitization, and increasing the need for greater stimulation (tolerance).
  2. Cambridge University logoNeural Correlates of Sexual Cue Reactivity in Individuals with and without Compulsive Sexual Behaviours (2014) - The first in a series of Cambridge University studies found the same brain activity as seen in drug addicts and alcoholics. It also found that porn addicts fit the accepted addiction model of wanting "it" more, but not liking "it" more. One other major finding was that 60% of subjects (average age: 25) had difficulty achieving erections/arousal with real partners, yet could achieve erections with porn.
  3. Enhanced Attentional Bias towards Sexually Explicit Cues in Individuals with and without Compulsive Sexual Behaviours (2014) - "Our findings of enhanced attentional bias... suggest possible overlaps with enhanced attentional bias observed in studies of drug cues in disorders of addictions."

These study results are consistent with 90 internet addiction brain studies, many of which also include internet porn use. In short, there's ample (and growing) peer-reviewed scientific support for the addiction model.

What happens when you drop a male rat into a cage with a receptive female rat? First, you see a frenzy of copulation. Then, progressively, the male tires of that particular female. Even if she wants more, he has had enough. However, replace the original female with a fresh one, and the male immediately revives and gallantly struggles to fertilize her.

Sex on the Brain: What Brain Plasticity Teaches About Internet Porn (2014), Norman Doidge, MD

Hungarian ReviewExcerpts: "We are in the midst of a revolution in sexual and romantic tastes unlike any other in history, a social experiment being performed on children and teenagers... What clinicians don’t know much about, yet, is how we shall help teenagers, whose sexual tastes are being influenced by porn, because this level of porn exposure is quite new. Will these influences and tastes turn out to be superficial? Or will the new porn scenarios deeply embed themselves because the teen years are still a formative period?"

Age 28 - Mild PIED cured in 35 days. Erections are very strong.
