The study finds significant reduction in brain activity in some parts of the brain associated with porn use. The scientists were not able to determine whether this reduced brain activity is a cause of increased interest in porn or whether the porn use causes the reduced brain function, though they hypothesize that over-stimulation of the brain's reward center could be the cause of impaired brain function elsewhere. Either way, I think it's safe to say that it's smart to avoid porn.
Here's the abstract:
Importance Since pornography appeared on the Internet, the accessibility, affordability, and anonymity of consuming visual sexual stimuli have increased and attracted millions of users. Based on the assumption that pornography consumption bears resemblance with reward-seeking behavior, novelty-seeking behavior, and addictive behavior, we hypothesized alterations of the frontostriatal network in frequent users.
Objective To determine whether frequent pornography consumption is associated with the frontostriatal network.
Design, Setting, and Participants Sixty-four healthy male adults with a broad range of pornography consumption at the Max Planck Institute for Human Development in Berlin, Germany, reported hours of pornography consumption per week. Pornography consumption was associated with neural structure, task-related activation, and functional resting-state connectivity.
Main Outcomes and Measures Gray matter volume of the brain was measured by voxel-based morphometry and resting state functional connectivity was measured on 3-T magnetic resonance imaging scans.
Results We found a significant negative association between reported pornography hours per week and gray matter volume in the right caudate (P < .001, corrected for multiple comparisons) as well as with functional activity during a sexual cue–reactivity paradigm in the left putamen (P < .001). Functional connectivity of the right caudate to the left dorsolateral prefrontal cortex was negatively associated with hours of pornography consumption.
Conclusions and Relevance The negative association of self-reported pornography consumption with the right striatum (caudate) volume, left striatum (putamen) activation during cue reactivity, and lower functional connectivity of the right caudate to the left dorsolateral prefrontal cortex could reflect change in neural plasticity as a consequence of an intense stimulation of the reward system, together with a lower top-down modulation of prefrontal cortical areas. Alternatively, it could be a precondition that makes pornography consumption more rewarding.
In all seriousness, the impact of porn on people's lives is dramatic in many cases, though they rarely see it themselves. They do not see how their attitudes toward other become more callous, how they become less sensitive and thoughtful, how they become less trustworthy and sometimes, a bit creepy. And surprisingly, some porn users, especially self-styled intellectuals, feel that porn use is what smart people do. Wrong direction, folks. I've seen too much pain and heartache from porn, too many failed marriages and damaged relationships, and just way too much reduced brain function. Do something good for your brain (and spirit) today and flee from porn in every form.

For Christians, the call is the same. Whether our bodies are predisposed to sin or have suffered the effects, we are called by Paul: "I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect."
(Romans 12:1-2 ESV)
Jeff,
Thank you for your overview and link to the interesting article. In light of the horrific pornography plague that is washing over the youth of the church I would have to say that I believe that to say one is stupid if they do porn is quite harsh. In fact I have see the opposite in so many cases, it is the best and the brightest that are being entrapped. A great site to look for more information on this is here http://www.lifechangingservices.org/sonsofhelaman/.
Thanks!
