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.

Age 32 - 60 days Fapfree and I have never been happier.

young couple2 Months! I never thought I'd be here.. I mean - I never thought in my life, that I would be celebrating a milestone like this. But here I am.. 60 days Fapfree and I have never been happier.

Age 30 - ED cured: feel like a normal person again, capable of having a real relationship.

couple on the grassI'm going to keep this brief, I'm really just writing because the success stories have kept me going during the hard times so it's time I shared mine. I've been a PMO addict for about a decade now (fapping compulsively for even longer but not with porn).

London Times feature by Gary Wilson - "A cure for porn addicts who have lost that loving feeling"

Sunday Times logoYoung men are finding that addiction to hardcore videos is harming their physical ability to have real sex. Gary Wilson explains how science and online discussion groups are helping them to quit

In 2007, something strange happened on the internet. I know, something strange is always happening on the internet. But this wasn’t a viral sensation that came and went in a few weeks. Hundreds and then thousands of people, mostly male, mostly young, started questioning the effects of online pornography. On websites for body-builders, ‘pick-up artists’, medical-advice seekers, car enthusiasts, even guitarists – wherever men gathered online – conversations turned to porn and what it was doing to them.

Age 26 - Female: I feel like a changed woman!!! Our sex together has become so much more fruitful and connected.

happy coupleI am a 26 year old female. I was in a pretty fruitless long term relationship where I was able to utilize porn to pick up the slack. After the relationship ended, I definitely increased my porn use to every day. I met my now fiance and we have sex pretty regularly.

Age 16 - I honestly have never felt this happy in my life. I feel like myself again.

happy guyI honestly really don't even know what to say right now. I'm super excited I've made it this far; I remember the days when I literally used to imagine and dream about this. I feel obligated to share my story and motives before getting into how NoFap has affected me.

Age 21 - I wrote a 180,000 words novel in three months!

novelist at workWow. I can't believe I did this. 180k is a lot. That's just a bit less than Harry Potter 4, just to give you an idea. Sure, I got a big correction to do now, but I've created something out of simple words.

"Another Study Links Compulsive Sexual Behavior to Other Forms of Addiction" by Robert Weiss LCSW

biasStatus Quo (For Now). In mid-July I published a blog discussing a recently released fMRI (brain imaging) study showing that the brain activity of sex addicts, when they are shown pornography, mirrors the brain activity of drug addicts when they are exposed to drug-related imagery.

Age 37 - ED is rarely a problem for me now. Relationship between my wife and I has drastically improved.

happy coupleI want to start by saying that I feel to be somewhat in the minority here, since I am older and married 18 years - that's more years than some of you have been alive. I'm not doing this in hard mode, and I am trying to have sex as often as I feel comfortable doing so.

Age 24 - ED cured: I'm 2 months away from 1 year fap free, its mind blowing to say the least.

mind blownMan has it been a long time since i was here! I can't believe I'm 2 months away from 1 year fap free, its mind blowing to say the least. I have certainly changed over the time I've been doing this, I met a girl about 6 months ago and we started dating not long after.
