Pornography addiction is a conceptual model assessing behavioral addiction characterized by compulsive, repeated use of pornographic material until it causes serious negative consequences to one's physical, mental, social, or financial well-being. However, the existence of pornography addiction has been hotly contested by scientists and clinicians. Addiction to Internet pornography is also a form of cybersex addiction.
Problematic Internet pornography viewing is viewing of Internet pornography that is problematic for an individual due to personal or social reasons, including excessive time spent viewing pornography instead of interacting with others. Individuals may report depression, social isolation, career loss, decreased productivity, or financial consequences as a result of their excessive Internet pornography viewing impeding on their social life.
Most studies of prevalence use a convenience sample. One study of a convenience sample of 9,265 people found that 1% of Internet users are clearly addicted to cybersex and 17% of users meet criteria for problematic sexual compulsivity, meaning they score above one standard deviation of the mean on the Kalichman Sexual Compulsivity Scale. A survey of 84 college-age males found that 20–60% of a sample of college-age males who use pornography found it to be problematic. Research on Internet addiction disorder indicates rates may range from 1.5 to 8.2% in Europeans and Americans. Internet pornography users are included in Internet users, and Internet pornography has been shown to be the Internet activity most likely to lead to compulsive disorders.
Status as addiction
Current experimental models of addiction to natural rewards and drug reward demonstrate common alterations in gene expression in the mesocorticolimbic projection. ΔFosB is the most significant gene transcription factor involved in addiction, since its viral or genetic overexpression in the nucleus accumbens is necessary and sufficient for most of the neural adaptations and plasticity that occur; it has been implicated in addictions to alcohol, cannabinoids, cocaine, nicotine, opioids, phenylcyclidine, and substituted amphetamines. ΔJunD is the transcription factor which directly opposes ΔFosB. Increases in nucleus accumbens ΔJunD expression can reduce or, with a large increase, even block most of the neural alterations seen in chronic drug abuse (i.e., the alterations mediated by ΔFosB).
ΔFosB also plays an important role in regulating behavioral responses to natural rewards, such as palatable food, sex, and exercise. Natural rewards, like drugs of abuse, induce ΔFosB in the nucleus accumbens, and chronic acquisition of these rewards can result in a similar pathological addictive state. Thus, ΔFosB is also the key transcription factor involved in addictions to natural rewards as well, and sex addictions in particular, since ΔFosB in the nucleus accumbens is critical for the reinforcing effects of sexual reward. Research on the interaction between natural and drug rewards suggests that psychostimulants and sexual reward possess cross-sensitization effects and act on common biomolecular mechanisms of addiction-related neuroplasticity which are mediated through ΔFosB.
The current Diagnostic and Statistical Manual of Mental Disorders (DSM-5) includes a new section for behavioral addictions, but includes only one disorder: pathological gambling, while only one other behavioral addiction, Internet gaming disorder, belongs to the conditions proposed for further study in DSM-5. Psychiatrists cited a lack of research support for refusing to include other behavioral disorders at this time.
While pornography is mentioned inside DSM-5 when discussing several paraphilias, there is no such thing as pornography addiction or health hazard due to porn consumption, according to DSM-5. DSM-5 does not consider pornography to be a mental health problem.
In 2011, the American Society of Addiction Medicine published a definition of addiction that for the first time stated that addiction includes pathological pursuit of all kinds of external rewards and not just substance dependence. This definition does not explicitly include porn addiction. Instead ASAM uses the phrase, "sexual behavior addiction".
The status of pornography addiction as an addictive disorder, rather than simply a compulsivity, has been hotly contested, particularly by a small group of researchers.[unreliable medical source?] However, their work has been challenged in the peer-reviewed literature.[unreliable medical source?]
However, Dr. Richard Krueger, DSM-5 work-group member (Sexual and Gender Identity Disorders) and associate clinical professor of psychiatry at Columbia University’s College of Physicians and Surgeons, has said that he "has little doubt porn addiction is real and will eventually garner enough attention to be recognized as a mental illness" by the DSM.[unreliable medical source?] Krueger also stated "most people would do it and it won’t become a problem" and recognized that there is yet no academic evidence for considering it a mental disorder.[unreliable medical source?]
Symptoms and diagnosis
Accepted diagnostic criteria do not exist for pornography addiction or problematic pornography viewing. The only diagnostic criteria for a behavioral addiction in the current Diagnostic and Statistical Manual of Mental Disorders are for pathological gambling, and they are similar to those for substance abuse and dependence, such as preoccupation with the behavior, diminished ability to control the behavior, tolerance, withdrawal, and adverse psychosocial consequences. Diagnostic criteria have been proposed for other behavioral addictions, and these are usually also based on established diagnoses for substance abuse and dependence.
A proposed diagnosis for hypersexual disorder includes pornography as a sub-type of this disorder. It included such criteria as time consumed by sexual activity interfering with obligations, repetitive engagement in sexual activity in response to stress, repeated failed attempts to reduce these behaviors, and distress or impairment of life functioning. A study on problematic Internet pornography viewing used the criteria of viewing Internet pornography more than three times a week during some weeks, and viewing causing difficulty in general life functioning.
A 2014 released study identified a connection between a subjects religious beliefs and their self perception of pornography addiction. The study's lead author is Case Western Reserve University psychology doctoral student Joshua Grubbs; the study is titled "Transgression as Addiction: Religiosity and Moral Disapproval as Predictors of Perceived Addiction to Pornography" and was published in the journal Archives of Sexual Behaviour. One of the findings of the study is that the results strongly indicate a predilection in religious people to believe they are addicted to pornography regardless of how much they watch or whether it negatively impacts their lives.
Cognitive-behavioral therapy has been suggested as a possible effective treatment for pornography addiction based on its success with Internet addicts, though no clinical trials have been performed to assess effectiveness among pornography addicts as of 2012. Acceptance and commitment therapy has also been shown to be a potentially effective treatment for problematic Internet pornography viewing.
Sex researcher Alvin Cooper and colleagues suggested several reasons for using filters as a therapeutic measure, including curbing accessibility that facilitates problematic behavior and encouraging clients to develop coping and relapse prevention strategies. Cognitive therapist Mary Anne Layden suggested that filters may be useful in maintaining environmental control. Internet behavior researcher David Delmonico stated that, despite their limitations, filters may serve as a "frontline of protection."

"Cross-sensitization is also bidirectional, as a history of amphetamine administration facilitates sexual behavior and enhances the associated increase in NAc DA ... As described for food reward, sexual experience can also lead to activation of plasticity-related signaling cascades. The transcription factor delta FosB is increased in the NAc, PFC, dorsal striatum, and VTA following repeated sexual behavior (Wallace et al., 2008; Pitchers et al., 2010b). This natural increase in delta FosB or viral overexpression of delta FosB within the NAc modulates sexual performance, and NAc blockade of delta FosB attenuates this behavior (Hedges et al, 2009; Pitchers et al., 2010b). Further, viral overexpression of delta FosB enhances the conditioned place preference for an environment paired with sexual experience (Hedges et al., 2009). ... In some people, there is a transition from “normal” to compulsive engagement in natural rewards (such as food or sex), a condition that some have termed behavioral or non-drug addictions (Holden, 2001; Grant et al., 2006a). ... In humans, the role of dopamine signaling in incentive-sensitization processes has recently been highlighted by the observation of a dopamine dysregulation syndrome in some patients taking dopaminergic drugs. This syndrome is characterized by a medication-induced increase in (or compulsive) engagement in non-drug rewards such as gambling, shopping, or sex (Evans et al, 2006; Aiken, 2007; Lader, 2008)."

Importantly, genetic or viral overexpression of ΔJunD, a dominant negative mutant of JunD which antagonizes ΔFosB- and other AP-1-mediated transcriptional activity, in the NAc or OFC blocks these key effects of drug exposure14,22–24. This indicates that ΔFosB is both necessary and sufficient for many of the changes wrought in the brain by chronic drug exposure. ΔFosB is also induced in D1-type NAc MSNs by chronic consumption of several natural rewards, including sucrose, high fat food, sex, wheel running, where it promotes that consumption14,26–30. This implicates ΔFosB in the regulation of natural rewards under normal conditions and perhaps during pathological addictive-like states."

"It has been found that deltaFosB gene in the NAc is critical for reinforcing effects of sexual reward. Pitchers and colleagues (2010) reported that sexual experience was shown to cause DeltaFosB accumulation in several limbic brain regions including the NAc, medial pre-frontal cortex, VTA, caudate, and putamen, but not the medial preoptic nucleus. Next, the induction of c-Fos, a downstream (repressed) target of DeltaFosB, was measured in sexually experienced and naive animals. The number of mating-induced c-Fos-IR cells was significantly decreased in sexually experienced animals compared to sexually naive controls. Finally, DeltaFosB levels and its activity in the NAc were manipulated using viral-mediated gene transfer to study its potential role in mediating sexual experience and experience-induced facilitation of sexual performance. Animals with DeltaFosB overexpression displayed enhanced facilitation of sexual performance with sexual experience relative to controls. In contrast, the expression of DeltaJunD, a dominant-negative binding partner of DeltaFosB, attenuated sexual experience-induced facilitation of sexual performance, and stunted long-term maintenance of facilitation compared to DeltaFosB overexpressing group. Together, these findings support a critical role for DeltaFosB expression in the NAc in the reinforcing effects of sexual behavior and sexual experience-induced facilitation of sexual performance. ... both drug addiction and sexual addiction represent pathological forms of neuroplasticity along with the emergence of aberrant behaviors involving a cascade of neurochemical changes mainly in the brain's rewarding circuitry."

Sexual behavior is highly rewarding (Tenk et al., 2009), and sexual experience causes sensitized drug-related behaviors, including cross-sensitization to amphetamine (Amph)-induced locomotor activity (Bradley and Meisel, 2001; Pitchers et al., 2010a) and enhanced Amph reward (Pitchers et al., 2010a). Moreover, sexual experience induces neural plasticity in the NAc similar to that induced by psychostimulant exposure, including increased dendritic spine density (Meisel and Mullins, 2006; Pitchers et al., 2010a), altered glutamate receptor trafficking, and decreased synaptic strength in prefrontal cortex-responding NAc shell neurons (Pitchers et al., 2012). Finally, periods of abstinence from sexual experience were found to be critical for enhanced Amph reward, NAc spinogenesis (Pitchers et al., 2010a), and glutamate receptor trafficking (Pitchers et al., 2012). These findings suggest that natural and drug reward experiences share common mechanisms of neural plasticity"
