Brain Scan Studies on Porn Users

At this time, two studies have examined the brains of porn users:

  1. Max Planck Institute logoBrain 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 logoCambridge University: Brain scans find porn addiction (2014). This is the first in a series of studies. It 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.

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.

Interview with Noah B.E. Church (author of WACK)

Noah B.E. ChurchNoah B. E. Church is a wildland firefighter, EMT, tutor, entrepreneur, speaker, and author. At 24 years old, he’s also a recovering porn addict. Having first encountered internet pornography at the age of nine, it wasn’t until very recently that he realised how badly his porn habit had affected his sexual and emotional well-being.

Following his recovery, Church wrote down his own story as a form of catharsis, but this soon grew in a short non-fiction title, Wack: Addicted to Internet Porn, which he released earlier this year. The book is an attempt to look at current research into porn addiction, and to help others realise the negative effect it could be having on their lives, and escape the addiction.

Enhanced Attentional Bias towards Sexually Explicit Cues in Individuals with and without Compulsive Sexual Behaviours (2014)

Cambridge University logoComments: This is another Cambridge University study on internet porn addicts. This one is a cue-reactivity test (attentional bias), which meticulously follows established neuroscience protocols. The subjects were all male and heterosexual (average age 24). Subjects were screened with a battery of tests & questionnaires to avoid confounds. Two control groups consisted of healthy heterosexual males who were, age, sex, and IQ, matched. Results mirror results seen in substance abusers, and dovetail with an earlier brain study on porn addicts.
