Scientific studies on porn addiction

07.04.2023 · May 15, 2020

Do you know any large-scale quantitative scientific studies on porn addiction?
If so, please share.
In case there are none (I was not able to find yet), let's conduct one together

Could include: time to recovery, successful recovery strategies, peer support, relation with other addictions or behavior anomalies, statistical significance of physical or psychological abuse during childhood, distribution across different demographics, age at first exposure, etc.

Hi
A long time ago, I heard in a video:
"Scientific studies in this matter are difficult to achieve because there is no group of control. This group of control would be people who never watch pornography. Sure there are a few, but they do not live the same life of common people. Both populations would not be comparable, because there would be a lot of side factors, such as diet, exercise, habits...
Nowadays every male teenager is introduced to pron at a young age. It's like in an alternate reality in which scientists want to search the relationship between between the increase of lung cancer and smoking but everyone smokes, how could they measure the effect of smoking?"

Here is a scientific article, I've found. It's like a review if you want to look at the data about a specific affirmation, you can open the references, a lot of the cited articles are for free:

Thank you for this. I'll look into this.
Also, you have a good point with the control group.

Go on scholar.google.com and use keywords "compulsive sexual behavior," "problematic pornography use," "perceived addiction to internet pornography," "hypersexual disorder"

Hi
Last week I remembered I had seen articles in a coment. I had read two of them, but last week I couldn't find.
Finally, I've found those articles in that coment that I want to share with you.

Brain Structure and Functional Connectivity Associated With Pornography Consumption

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.

Can Pornography be Addictive? An fMRI Study of Men Seeking Treatment for Problematic Pornography Use

Abstract
Pornography consumption is highly prevalent, particularly among young adult males. For some individuals, problematic pornography use (PPU) is a reason for seeking treatment. Despite the pervasiveness of pornography, PPU appears under-investigated, including with respect to the underlying neural mechanisms. Using functional magnetic resonance imaging (fMRI), we examined ventral striatal responses to erotic and monetary stimuli, disentangling cue-related ‘wanting’ from reward-related ‘liking’ among 28 heterosexual males seeking treatment for PPU and 24 heterosexual males without PPU. Subjects engaged in an incentive delay task in the scanner, in which they received erotic or monetary rewards preceded by predictive cues. Blood-oxygen-level-dependent responses to erotic and monetary cues were analyzed and examined with respect to self-reported data on sexual activity collected over the 2 preceding months. Men with and without PPU differed in their striatal responses to cues predicting erotic pictures but not in their responses to erotic pictures. PPU subjects when compared with control subjects showed increased activation of ventral striatum specifically for cues predicting erotic pictures but not for cues predicting monetary gains. Relative sensitivity to cues predicting erotic pictures vs monetary gains was significantly related to the increased behavioral motivation to view erotic images (suggestive of higher ‘wanting’), severity of PPU, amount of pornography use per week, and number of weekly masturbations. Our findings suggest that, similar to what is observed in substance and gambling addictions, the neural and behavioral mechanisms associated with the anticipatory processing of cues specifically predicting erotic rewards relate importantly to clinically relevant features of PPU. These findings suggest that PPU may represent a behavioral addiction and that interventions helpful in targeting behavioral and substance addictions warrant consideration for adaptation and use in helping men with PPU.

Ventral striatum activity when watching preferred pornographic pictures is correlated with symptoms of Internet pornography addiction

Abstract
One type of Internet addiction is excessive pornography consumption, also referred to as cybersex or Internet pornography addiction. Neuroimaging studies found ventral striatum activity when participants watched explicit sexual stimuli compared to non-explicit sexual/erotic material. We now hypothesized that the ventral striatum should respond to preferred pornographic compared to non-preferred pornographic pictures and that the ventral striatum activity in this contrast should be correlated with subjective symptoms of Internet pornography addiction. We studied 19 heterosexual male participants with a picture paradigm including preferred and non-preferred pornographic materials. Subjects had to evaluate each picture with respect to arousal, unpleasantness, and closeness to ideal. Pictures from the preferred category were rated as more arousing, less unpleasant, and closer to ideal. Ventral striatum response was stronger for the preferred condition compared to non-preferred pictures. Ventral striatum activity in this contrast was correlated with the self-reported symptoms of Internet pornography addiction. The subjective symptom severity was also the only significant predictor in a regression analysis with ventral striatum response as dependent variable and subjective symptoms of Internet pornography addiction, general sexual excitability, hypersexual behavior, depression, interpersonal sensitivity, and sexual behavior in the last days as predictors. The results support the role for the ventral striatum in processing reward anticipation and gratification linked to subjectively preferred pornographic material. Mechanisms for reward anticipation in ventral striatum may contribute to a neural explanation of why individuals with certain preferences and sexual fantasies are at-risk for losing their control over Internet pornography consumption.

Altered Appetitive Conditioning and Neural Connectivity in Subjects With Compulsive Sexual Behavior

Results
As a main result, we found increased amygdala activity during appetitive conditioning for the CS+ vs the CS- and decreased coupling between the ventral striatum and prefrontal cortex in the CSB vs control group.
Conclusion
The findings show that neural correlates of appetitive conditioning and neural connectivity are altered in patients with CSB. The increased amygdala activation might reflect facilitated conditioning processes in patients with CSB. In addition, the observed decreased coupling could be interpreted as a marker for impaired emotion regulation success in this group.
