Research confirms sharp rise in youthful sexual dysfunctions

Young men today appear to be experiencing a sharp increase in ED (and other sexual dysfunctions) since the advent of streaming internet. All studies assessing young male sexuality since 2010 report historic levels of erectile dysfunction, and startling rates of a new scourge: low libido.

Erectile dysfunction rates ranged from 27 to 33%, while rates for low libido (hypo-sexuality) ranged from 16% to 37%. The lower ranges are taken from studies involving teens and men 25 and under, while the higher ranges are from studies involving men 40 and under.

These high rates are a recent phenomenon, but comparing ED rates in men over time can be challenging. Traditionally, ED rates have been negligible in young men, and did not begin to rise sharply until after age 40. For example, here’s a graph from a Dutch study comparing data from prior to 2004.

The next challenge is to understand the extent to which ED rates have risen. This is thorny because ED rates have been measured using various different instruments in the last 25 years. Some researchers asked a single (yes/no) question and requested those with ED to rate its severity. Others use a 5- or 6-question version of a more recent instrument that employs Likert scales. It’s called the IIEF (The International Index of Erectile Function), and is used widely today. Still other researchers used different questionnaires.

GSSAB ED results over time

We’ll discuss a number of study results that show the upward trend, but let’s start with some of the most irrefutable research. It demonstrates a radical rise in ED rates over a decade using very large samples (which increase reliability). All the men were assessed using the same (yes/no) question about ED, as part of the Global Study of Sexual Attitudes and Behavior (GSSAB), administered to 13,618 sexually active men in 29 countries. That occurred in 2001-2002. A decade later, in 2011, the same “sexual difficulties” (yes/no) question from the GSSAB was administered to 2,737 sexually active men in Croatia, Norway and Portugal. The first group, in 2001-2002, were aged 40-80. The second group, in 2011, were 40 and under.

Based on the findings of prior studies one would predict the older men would have far higher ED scores than the younger men, whose scores should have been negligible. Not so. In just a decade, things had changed radically. The 2001-2002 ED rates for men 40-80 were about 13% in Europe. By 2011, ED rates in young Europeans, 18-40, ranged from 14-28%!

What changed in men’s sexual environment during this time? Well, major changes were internet penetration and access to porn videos (followed by access to streaming porn in 2006, and then smartphones on which to view it). In the 2011 study on Croatians, Norwegians and Portuguese, the Portuguese had the lowest rates of ED and the Norwegians had the highest. In 2013, internet penetration rates in Portugal were only 67%, compared with 95% in Norway.

Historical ED rates

What about other historical rates of ED in peer-reviewed literature using various instruments? First, here are results from the 2 major cross-sectional studies on ED in sexually active American men. Both predated heavy internet penetration.

  1. In the 1940s, the Kinsey report concluded that the prevalence of ED was less than 1% in men younger than 30 years, less than 3% in those 30–45.
  2. A 1999 cross-sectional study (based on data gathered in 1992) published by the Journal of the American Medical Association reported erectile dysfunction rates of only 5%, and low sexual desire in 5%. In that study, the ages of the men surveyed ranged from 18 to 59, so a third of them were over 40, which means the rates for sexually active men under 40 were lower.

In 2002 Dutch researchers did a meta-analysis of 6 high-quality ED studies. All of the studies reviewed from Europe (5) reported ED rates for men under 40 of approximately 2%. The sixth was the one reported immediately above.

Note: Keep in mind that ED rates for all men in every age group are higher than rates for sexually active men. For example, in the 1992 data for sexually active men 18-59, the average ED rate was only 5%. However, the rates for men (both sexually active and not) were 7% in men 18-29, 9% in men 30-39, 11% in men 40-49, and 18% in men 50-59. In order to compare “apples to apples,” we, like most researchers, focus on rates for sexually active men. This unfortunately fails to count ED problems in young men who avoid sex due to porn-induced sexual dysfunctions.

Before we turn back to recent studies, it’s important to understand a bit more about the pathology of erectile dysfunction. ED is usually classified as either psychogenic or organic. Traditionally, psychogenic ED is associated with psychological factors (e.g., depression, stress, or anxiety) while organic ED is attributed to physical conditions (e.g., neurological, hormonal, or anatomical.) The most common diagnosis for guys under 40 is psychogenic ED.

Studies investigating ED risk factors in men under 40 typically fail to find the causes commonly associated with ED in older men, such as smoking, alcoholism, obesity, sedentary life, diabetes, hypertension, cardiovascular disease, and hyperlipidemia. Be very skeptical if you read that the preceding causes of organic ED in older men are also the cause of a sharp rise in youthful ED. It takes years for various lifestyle factors to manifest as vasculogenic or neurogenic ED.

Recent studies on young men

Now, we turn to other recent studies on young men (~40 and under). Using the IIEF-5, a 2012 cross-sectional study of Swiss men aged 18-24 found ED rates of 30%, and a 2010 Brazilian study of men 18-40 reported ED rates of 35%. A 2013 Italian study reported one in four patients seeking help for new onset ED were younger than 40. Astonishingly, the rate of severe ED was nearly 10% higher in younger men than in men over 40. Also, a 2015 paper about 4,211 Italians who sought outpatient help for sexual dysfunction found that compulsive masturbators were younger than the other men and had higher rates of ED (and were likely masturbating to internet porn).

A 2014 study of new diagnoses of ED in active duty servicemen reported that rates had more than doubled between 2004 and 2013. Rates of psychogenic ED increased more than organic ED, and rates of unclassified ED remained relatively stable. A 2014 cross-sectional study of active duty, relatively healthy, male military personnel aged 21-40 found an overall ED rate of 33.2%, using the IIEF-5. About half of them also had PTSD (a known risk factor for ED). In a further military study published in 2015, the researchers found that ED was associated with sexual anxiety and genital self-image, both of which could easily be tied to heavy internet porn use.

The next three studies reveal that abnormally low sexual desire is also cropping up in young men.

  1. A 2014 study on Canadian adolescents reported that 53.5% of males aged 16-21 have symptoms indicative of a sexual problem. Erectile dysfunction was the most common (27%), followed by low sexual desire (24%), and problems with orgasm (11%). The authors were baffled why rates were so high, and were surprised that sexual dysfunction rates for males surpassed females, unlike in earlier published literature.
  2. The same Canadian researchers published a 2-year longitudinal study in 2016, in which they found that, over several checkpoints during the 2 years, the following percentages of 16-21 year old males reported:
    low sexual satisfaction (47.9%)
    low desire (46.2%)
    problems in erectile function (45.3%)
    While females’ sexual problems improved over time the males’ sexual problems did not: “Unlike for male adolescents, we found a clearer picture of improvement over time for female adolescents, suggesting that learning and experience played a role in improving their sexual lives.” And, “The only factor that emerged as a strong predictor was relationship status: Adolescents who were not in a sexual relationship were approximately three times more likely to report a problem in sexual functioning compared to those who were in a sexual relationship.” [All subjects were sexually active, but who would be using the most porn?]
  3. The same Canadian researchers published a 2-year longitudinal study in 2016, in which they found that, over several checkpoints during the 2 years, the following percentages of 16-21 year old males reported:
    1. low sexual satisfaction (47.9%)
    2. low desire (46.2%)
    3. problems in erectile function (45.3%)
  4. A 2015 study on Italian high school seniors (18-19) found that 16% of those who use porn more than once per week  reported abnormally low sexual desire. Non-porn users reported 0% low sexual desire.
  5. A 2014 survey of Croatian men 40 and under reported ED rates of 31% and low sexual desire rates of 37%.

A 2015 study, which asked Canadian men using porn 7 or more hours per week about their sexual functioning, found that 71% had sexual dysfunctions, with 33% reporting difficulty orgasming. Average age 41.5.

Together, these studies suggest a recent increase in ED in men ~40 and under, as well as startling rates of anorgasmia and low sexual desire, starting quite young (as does internet porn use).

None of these studies had young men remove porn use to investigate internet porn’s effects on their sexual performance, despite the fact that its use represents a drastic change in men’s sexual environment in the digital age. However, in this Israeli case series, researchers asked a man with porn-induced low libido and anorgasmia to stop using porn and take a time-out from masturbation. He had escalated through several genres of porn and experienced little desire for partnered sex. An 8-month reboot (avoiding porn) led to normal libido and enjoyable sexual relations.

In line with anecdotal  evidence and peer-reviewed research

The image to the right appeared in an analysis of ED posts from MedHelp forums. “Nearly 60% of men posting on the forums were under 24 years old. This was a surprising finding for researchers, as erectile dysfunction is generally considered a condition that strikes older men.”

An Irish Times poll asked thousands of readers about ED, and the number of men 24-34 with issues was 28%:

Already, a handful of studies have correlated use of internet porn and porn addiction with arousal, attraction, and sexual performance problems. Results link its use with diminished libido or erectile function, delayed ejaculation, a preference for using porn to achieve and maintain arousal over having sex with a partner, negative effects on partnered sex, decreased enjoyment of sexual intimacy, and lower brain activation to sexual images:

UPDATE –  Is Internet Pornography Causing Sexual Dysfunctions? A Review with Clinical Reports (2016) – An extensive review of the literature related to porn-induced sexual problems. Involving US Navy doctors, the review provides the latest data revealing a tremendous rise in youthful sexual problems. It also reviews the neurological studies related to porn addiction and sexual conditioning via Internet porn. The doctors provide 3 clinical reports of men who developed porn-induced sexual dysfunctions.

1) The Dual Control Model – The Role Of Sexual Inhibition & Excitation In Sexual Arousal And Behavior (2007) – Newly rediscovered and very convincing. In an experiment employing video porn, 50% of the young men couldn’t become aroused or achieve erections with porn (average age was 29). The shocked researchers discovered that the men’s erectile dysfunction was,

related to high levels of exposure to and experience with sexually explicit materials.

The men experiencing erectile dysfunction had spent a considerable amount of time in bars and bathhouses where porn was “omnipresent,” and “continuously playing“. The researchers stated:

“Conversations with the subjects reinforced our idea that in some of them a high exposure to erotica seemed to have resulted in a lower responsivity to “vanilla sex” erotica and an increased need for novelty and variation, in some cases combined with a need for very specific types of stimuli in order to get aroused.”

2) Neural Correlates of Sexual Cue Reactivity in Individuals with and without Compulsive Sexual Behaviours (2014) – This fMRI study by Cambridge University found sensitization in porn addicts which mirrored sensitization in drug addicts. It also found that porn addicts fit the accepted addiction model of wanting “it” more, but not liking “it” more. The researchers also reported that 60% of subjects (average age: 25) had difficulty achieving erections/arousal with real partners as a result of using porn, yet could achieve erections with porn. From the study (CSB is compulsive sexual behaviours):

“CSB subjects reported that as a result of excessive use of sexually explicit materials…..[they] experienced diminished libido or erectile function specifically in physical relationships with women (although not in relationship to the sexually explicit material)”

“Compared to healthy volunteers, CSB subjects had greater subjective sexual desire or wanting to explicit cues and had greater liking scores to erotic cues, thus demonstrating a dissociation between wanting and liking. CSB subjects also had greater impairments of sexual arousal and erectile difficulties in intimate relationships but not with sexually explicit materials highlighting that the enhanced desire scores were specific to the explicit cues and not generalized heightened sexual desire.”

3) Online sexual activities: An exploratory study of problematic and non-problematic usage patterns in a sample of men (2016) – This Belgian study from a leading research university found problematic Internet porn use was associated with reduced erectile function and reduced overall sexual satisfaction. Yet problematic porn users experienced greater cravings. The study appears to report escalation, as 49% of the men viewed porn that “was not previously interesting to them or that they considered disgusting.” Excerpts:

This study is the first to directly investigate the relationships between sexual dysfunctions and problematic involvement in OSAs. Results indicated that higher sexual desire, lower overall sexual satisfaction, and lower erectile function were associated with problematic OSAs (online sexual activities). These results can be linked to those of previous studies reporting a high level of arousability in association with sexual addiction symptoms (Bancroft & Vukadinovic, 2004; Laier et al., 2013; Muise et al., 2013).”

In addition, we finally have a study that asks porn users about possible escalation to new or disturbing porn genres. Guess what it found?

Forty-nine percent mentioned at least sometimes searching for sexual content or being involved in OSAs that were not previously interesting to them or that they considered disgusting, and 61.7% reported that at least sometimes OSAs were associated with shame or guilty feelings.”

Note –  This is the first study to directly investigate the relationships between sexual dysfunctions and internet porn use. Two other studies claiming to have investigated correlations between porn use and erectile functioning cobbled together data from earlier studies in an unsuccessful attempt to debunk porn-induced ED. Both were criticized in the peer-reviewed literature: paper 1 was not an authentic study, and has been thoroughly discredited; paper 2 actually found correlations that support porn-induced ED. Moreover, paper 2 was only a “brief communication” that did not report important data.

4) Adolescents and web porn: a new era of sexuality (2015) – This Italian study analyzed the effects of Internet porn on high school seniors, co-authored by urology professor Carlo Foresta, president of the Italian Society of Reproductive Pathophysiology. The most interesting finding is that 16% of those who consume porn more than once a week report abnormally low sexual desire compared with 0% in non-consumers (and 6% for those who consume less than once a week). From the study:

“21.9% define it as habitual, 10% report that it reduces sexual interest towards potential real-life partners, and the remaining, 9.1% report a kind of addiction. In addition, 19% of overall pornography consumers report an abnormal sexual response, while the percentage rose to 25.1% among regular consumers.”

5) Patient Characteristics by Type of Hypersexuality Referral: A Quantitative Chart Review of 115 Consecutive Male Cases (2015) – Study on men (average age 41.5) with hypersexuality disorders, such as paraphilias and chronic masturbation or adultery. 27 were classified as “avoidant masturbators,” meaning they masturbated (typically with porn use) one or more hours per day or more than 7 hours per week. 71% reported sexual functioning problems, with 33% reporting delayed ejaculation (a precursor to porn-induced ED). What sexual dysfunction do 38% of the remaining men have? The study doesn’t say, and the authors have ignored requests for details. Two primary choices for male sexual dysfunction are ED and low libido. The men were not asked about their erectile functioning without porn. If all their sexual activity involved masturbating to porn, and not sex with a partner, they might never realize they had porn-induced ED.

6) Altered Appetitive Conditioning and Neural Connectivity in Subjects With Compulsive Sexual Behavior (2016) – “Compulsive Sexual Behaviors” (CSB) means the men were porn addicts, because CSB subjects averaged nearly 20 hours of porn use per week. The controls averaged 29 minutes per week. Interestingly, 3 of the 20 CSB subjects mentioned to interviewers that they suffered from “orgasmic-erection disorder,” while none of the control subjects reported sexual problems.

7) Brain Structure and Functional Connectivity Associated With Pornography Consumption: The Brain on Porn (2014) – A Max Planck study which found 3 significant addiction-related brain changes correlating with the amount of porn consumed. It also found that the more porn consumed the less reward circuit activity in response to brief exposure (.530 second) to vanilla porn. In a 2014 article lead author Simone Kühn said:

We assume that subjects with a high porn consumption need increasing stimulation to receive the same amount of reward. That could mean that regular consumption of pornography more or less wears out your reward system. That would fit perfectly the hypothesis that their reward systems need growing stimulation.”

A more technical description of this study from a review of the literature by Kuhn & Gallinat – Neurobiological Basis of Hypersexuality (2016).

“The more hours participants reported consuming pornography, the smaller the BOLD response in left putamen in response to sexual images. Moreover, we found that more hours spent watching pornography was associated with smaller gray matter volume in the striatum, more precisely in the right caudate reaching into the ventral putamen. We speculate that the brain structural volume deficit may reflect the results of tolerance after desensitization to sexual stimuli.”

8) Sexual Desire, not Hypersexuality, is Related to Neurophysiological Responses Elicited by Sexual Images (2013) – This EEG study was touted in the media as evidence against the existence of porn addiction. Not so. In line with the Cambridge University brain scan studies, this EEG study reported greater cue-reactivity to porn correlated with less desire for partnered sex. To put another way – individuals with more brain activation and cravings for porn would rather masturbate to porn than have sex with a real person. Study spokesman Nicole Prause claimed that porn users merely had high libido, yet the results of the study say something quite different. Three peer-reviewed papers expose the truth: 1, 2, 3. Also see the extensive YBOP critique.

9) Modulation of Late Positive Potentials by Sexual Images in Problem Users and Controls Inconsistent with “Porn Addiction” (2015) – Another Nicole Prause EEG study. This time comparing the 2013 subjects from the above study to an actual control group. The results: compared to controls, “porn addicts” had less response to one-second exposure to photos of vanilla porn. The lead author, Nicole Prause, claimed these results debunk porn addiction. However, these findings align perfectly with Kühn & Gallinat (2014), which found that more porn use correlated with less brain activation in response to pictures of vanilla porn. Put simply, frequent porn users were desensitized and needed greater stimulation to achieve the same buzz. Four peer-reviewed papers say that Prause findings indicate desensitization, and addiction-related phenomenon: 1, 2, 3, 4 (also see this extensive YBOP critique). By the way, another EEG study found that greater porn use in women correlated with less brain activation to porn.

10) Unusual masturbatory practice as an etiological factor in the diagnosis and treatment of sexual dysfunction in young men (2014) – One of the 4 case studies in this paper reports on a man with porn-induced sexual problems (low libido, fetishes, anorgasmia). The sexual intervention called for a 6-week abstinence from porn and masturbation. After 8 months the man reported increased sexual desire, successful sex and orgasm, and enjoying “good sexual practices. This is the first peer-reviewed chronicling of a recovery from porn-induced sexual dysfunctions. Excerpts from the paper:

“When asked about masturbatory practices, he reported that in the past he had been masturbating vigorously and rapidly while watching pornography since adolescence. The pornography originally consisted mainly of zoophilia, and bondage, domination, sadism, and masochism, but he eventually got habituated to these materials and needed more hardcore pornography scenes, including transgender sex, orgies, and violent sex. He used to buy illegal pornographic movies on violent sex acts and rape and visualized those scenes in his imagination to function sexually with women. He gradually lost his desire and his ability to fantasize and decreased his masturbation frequency.”

In conjunction with weekly sessions with a sex therapist, the patient was instructed to avoid any exposure to sexually explicit material, including videos, newspapers, books, and internet pornography.

After 8 months, the patient reported experiencing successful orgasm and ejaculation. He renewed his relationship with that woman, and they gradually succeeded in enjoying good sexual practices.

11) Erectile Dysfunction, Boredom, and Hypersexuality among Coupled Men from Two European Countries (2015) – Survey reported a strong correlation between erectile dysfunction and measures of hypersexuality. The study omitted correlation data between erectile functioning and pornography use, but noted a significant correlation. An excerpt:

Among Croatian and German men, hypersexuality was significantly correlated with proneness to sexual boredom and more problems with erectile function.

12) Masturbation and Pornography Use Among Coupled Heterosexual Men With Decreased Sexual Desire: How Many Roles of Masturbation? (2015) – Masturbating to porn was related with decreased sexual desire and low relationship intimacy. Excerpts:

“Among men who masturbated frequently, 70% used pornography at least once a week. A multivariate assessment showed that sexual boredom, frequent pornography use, and low relationship intimacy significantly increased the odds of reporting frequent masturbation among coupled men with decreased sexual desire.”

“Among men [with decreased sexual desire] who used pornography at least once a week [in 2011], 26.1% reported that they were unable to control their pornography use. In addition, 26.7% of men reported that their use of pornography negatively affected their partnered sex and 21.1% claimed to have attempted to stop using pornography.”

13) Use of pornography in a random sample of Norwegian heterosexual couples (2009) – Porn use was correlated with more sexual dysfunctions in the man and negative self perception in the female. The couples who did not use porn had no sexual dysfunctions. A few excerpts from the study:

In couples where only one partner used pornography, we found more problems related to arousal (male) and negative (female) self-perception.

In those couples where one partner used pornography there was a permissive erotic climate. At the same time, these couples seemed to have more dysfunctions.

The couples who did not use pornography... may be considered more traditional in relation to the theory of sexual scripts. At the same time, they did not seem to have any dysfunctions.

Couples who both reported pornography use grouped to the positive pole on the ‘‘Erotic climate’’ function and somewhat to the negative pole on the ‘‘Dysfunctions’’ function.

14) Lecture describing upcoming studies – by Urology professor Carlo Foresta, president of the Italian Society of Reproductive Pathophysiology – The lecture contains the results of longitudinal and cross-sectional studies. One study involved a survey of high school teens (pages 52-53). The study reported that sexual dysfunction doubled between 2005 and 2013, with low sexual desire increasing 600%.

  • The percentage of teens that experienced alterations of their sexuality: 2004/05: 7.2%, 2012/13: 14.5%
  • The percentage of teens with low sexual desire: 2004/05: 1.7%, 2012/13: 10.3% (that’s a 600% increase in 8 years)

Foresta also describes his upcoming study, “Sexuality media and new forms of sexual pathology sample 125 young males, 19-25 years” (Italian name – “Sessualità mediatica e nuove forme di patologia sessuale Campione 125 giovani maschi“). The results from the study (pages 77-78), which used the International Index of Erectile Function Questionnaire, found that regular porn users scored 50% lower on sexual desire domain and 30% lower of the erectile functioning domain.

15) (not peer-reviewed) Here’s an article about an extensive analysis of comments and questions posted on MedHelp concerning erectile dysfunction. What’s shocking is that 58% of the men asking for help were 24 or younger. Many suspected that internet porn could be involved as described in the results from the study

EXCERPT: The most common phrase is “erectile dysfunction” – which is mentioned more than three times as often as any other phrase – followed by “internet porn,” “performance anxiety,” and “watching porn.”

Clearly, porn is a frequently discussed subject: “I have been viewing internet pornography frequently (4 to 5 times a week) for the past 6 years,” one man writes. “I am in my mid-20s and have had a problem getting and maintaining an erection with sexual partners since my late teens when I first started looking at internet porn.”

Studies reporting relationships between porn use and less sexual or relationship satisfaction:

1) Does Viewing Pornography Reduce Marital Quality Over Time? Evidence from Longitudinal Data (2016) – First longitudinal study on a representative cross-section of married couples. It found significant negative effects of porn use on marriage quality over time.  Excerpt:

This study is the first to draw on nationally representative, longitudinal data (2006-2012 Portraits of American Life Study) to test whether more frequent pornography use influences marital quality later on and whether this effect is moderated by gender. In general, married persons who more frequently viewed pornography in 2006 reported significantly lower levels of marital quality in 2012, net of controls for earlier marital quality and relevant correlates. Pornography’s effect was not simply a proxy for dissatisfaction with sex life or marital decision-making in 2006. In terms of substantive influence, frequency of pornography use in 2006 was the second strongest predictor of marital quality in 2012

2) Associations between young adults’ use of sexually explicit materials and their sexual preferences, behaviors, and satisfaction (2011) – Excerpts:

Higher frequencies of sexual explicit material (SEM) use were associated with less sexual and relationship satisfaction. The frequency of SEM use and number of SEM types viewed were both associated with higher sexual preferences for the types of sexual practices typically presented in SEM. These findings suggest that SEM use can play a significant role in a variety of aspects of young adults’ sexual development processes.

Specifically, higher viewing frequency was associated with less sexual and relationship satisfaction when controlling for gender, religiosity, dating status and the number of SEM types viewed.

Because a substantial proportion of the young adults in this study reported using SEM, the potential implications are especially noteworthy, particularly for young men.

3) Pornography’s Impact on Sexual Satisfaction (1988) – Excerpt:

Male and female students and nonstudents were exposed to videotapes featuring common, nonviolent pornography or innocuous content. Exposure was in hourly sessions in six consecutive weeks. In the seventh week, subjects participated in an ostensibly unrelated study on societal institutions and personal gratifications. [Porn use] strongly impacted self-assessment of sexual experience. After consumption of pornography, subjects reported less satisfaction with their intimate partners—specifically, with these partners’ affection, physical appearance, sexual curiosity, and sexual performance proper. In addition, subjects assigned increased importance to sex without emotional involvement. These effects were uniform across gender and populations.

4) Adolescents’ Exposure to Sexually Explicit Internet Material and Sexual Satisfaction: A Longitudinal Study (2009) – Excerpt:

Between May 2006 and May 2007, we conducted a three-wave panel survey among 1,052 Dutch adolescents aged 13–20. Structural equation modeling revealed that exposure to SEIM consistently reduced adolescents’ sexual satisfaction. Lower sexual satisfaction (in Wave 2) also increased the use of SEIM (in Wave 3). The effect of exposure to SEIM on sexual satisfaction did not differ among male and female adolescents.

5) Individuals who never viewed SEM reported higher relationship quality on all indices than those who viewed SEM alone (2011)Excerpt:

As expected, individuals who did not view SEM (sexually explicit material) at all reported lower negative communication and higher dedication than individuals who viewed SEM alone or both alone and with their partner.

6) Sexual media use and relational satisfaction in heterosexual couples (2010) – Excerpt:

Results revealed that a higher frequency of men’s sexual media use related to negative satisfaction in men, while a higher frequency of women’s sexual media use related to positive satisfaction in male partners. Reasons for sexual media use differed by gender: Men reported primarily using sexual media for masturbation, while women reported primarily using sexual media as part of lovemaking with their partners.

7) Young Adult Women’s Reports of Their Male Romantic Partner’s Pornography Use as a Correlate of Their Self-Esteem, Relationship Quality, and Sexual Satisfaction (2012) – Excerpt:

The purpose of this study was to examine the relationships between men’s pornography use, both frequency and problematic use, on their heterosexual female partner’s psychological and relational well-being among 308 young adult college women. Results revealed women’s reports of their male partner’s frequency of pornography use were negatively associated with their relationship quality. More perceptions of problematic use of pornography was negatively correlated with self-esteem, relationship quality, and sexual satisfaction.

8) Korean Men’s Pornography use, Their Interest in Extreme Pornography, and Dyadic Sexual Relationships (2014) – Excerpt:

Six-hundred eighty-five heterosexual South Korean male college students participated in an online survey. The majority (84.5%) of respondents had viewed pornography, and for those who were sexually active (470 respondents), we found that higher interest in degrading or extreme pornography was associated with the experience of role-playing sexual scenes from pornography with a partner, and a preference for using pornography to achieve and maintain sexual excitement over having sex with a partner.

We found that higher interest in viewing degrading or extreme pornography … has a significant positive … association with sexual concerns.

9) Pornography and the Male Sexual Script: An Analysis of Consumption and Sexual Relations (2014) – Excerpt:

We argue pornography creates a sexual script that then guides sexual experiences. To test this, we surveyed 487 college men (ages 18-29 years) in the United States to compare their rate of pornography use with sexual preferences and concerns. Results showed the more pornography a man watches, the more likely he was to use it during sex, request particular pornographic sex acts of his partner, deliberately conjure images of pornography during sex to maintain arousal, and have concerns over his own sexual performance and body image. Further, higher pornography use was negatively associated with enjoying sexually intimate behaviors with a partner.

10) Adult Social Bonds and Use of Internet Pornography (2004) – Excerpt:

Complete data on 531 Internet users are taken from the General Social Surveys for 2000. Social bonds measures include religious, marital, and political ties. Measures of participation in sexual and drug-related deviant lifestyles, and demographic controls are included. The results of a logistic regression analysis found that among the strongest predictors of use of cyberporn were weak ties to religion and lack of a happy marriage.

11) A Common-Fate Analysis of Pornography Acceptance, Use, and Sexual Satisfaction Among Heterosexual Married Couples (2016) – Excerpt:

Results indicated that the shared variance of pornography acceptance was positively associated with both spouses’ pornography use and that spouses’ pornography use was negatively associated with their own sexual satisfaction.Wives’ pornography use was found to be positively associated with the couple’s shared variance of sexual satisfaction, but pornography use did not significantly mediate the relationship between pornography acceptance and sexual satisfaction.

12) Differences in Pornography Use Among Couples: Associations with Satisfaction, Stability, and Relationship Processes (2016) – Excerpt:

The present study utilized a sample of 1755 adult couples in heterosexual romantic relationships to examine how different patterns of pornography use between romantic partners may be associated with relationship outcomes. While pornography use has been generally associated with some negative and some positive couple outcomes, no study has yet explored how differences between partners may uniquely be associated with relationship well-being. Results suggested that greater discrepancies between partners in pornography use were related to less relationship satisfaction, less stability, less positive communication, and more relational aggression. Mediation analyses suggested that greater pornography use discrepancies were primarily associated with elevated levels of male relational aggression, lower female sexual desire, and less positive communication for both partners which then predicted lower relational satisfaction and stability for both partners.

13) Factors Predicting Cybersex Use and Difficulties in Forming Intimate Relationships among Male and Female Users of Cybersex (2015)Excerpt:

This study used the Cybersex addiction test, Craving for pornography questionnaire, and a Questionnaire on intimacy among 267 participants (192 males and 75 females) mean age for males 28 and for females 25,  who were recruited from special sites that are dedicated to pornography and cybersex on the Internet. Results of regression analysis indicated that pornography, gender, and cybersex significantly predicted difficulties in intimacy and it accounted for 66.1% of the variance of rating on the intimacy questionnaire. Second, regression analysis also indicated that craving for pornography, gender, and difficulties in forming intimate relationships significantly predicted frequency of cybersex use and it accounted for 83.7% of the variance in ratings of cybersex use.

14) Pornography use: who uses it and how it is associated with couple outcomes (2013) – Excerpt:

This study examined associations among pornography use, the meaning people attach to its use, sexual quality, and relationship satisfaction. Participants were couples (N = 617 couples) who were either married or cohabiting at the time the data were gathered. Overall results from this study indicated substantial gender differences in terms of use profiles, as well as pornography’s association with relationship factors. Specifically, male pornography use was negatively associated with both male and female sexual quality, whereas female pornography use was positively associated with female sexual quality.

15) A Love That Doesn’t Last: Pornography Consumption and Weakened Commitment to One’s Romantic Partner (2012) – The study had subjects try to abstain from porn use for 3 weeks. Upon comparing the two groups, those who continued using pornography reported lower levels of commitment than those who tried to abstain. Excerpts:

Study 1 found that higher pornography consumption was related to lower commitment

Study 3 participants were randomly assigned to either refrain from viewing pornography or to a self-control task. Those who continued using pornography reported lower levels of commitment than control participants.

Study 5 found that pornography consumption was positively related to infidelity and this association was mediated by commitment. Overall, a consistent pattern of results was found using a variety of approaches including cross-sectional (Study 1), observational (Study 2), experimental (Study 3), and behavioral (Studies 4 and 5) data.

16) Male Partners’ Perceived Pornography Use and Women’s Relational and Psychological Health: The Roles of Trust, Attitudes, and Investment (2015) – Excerpt:

Results revealed that women’s reports of their male partners’ pornography use were related to less relationship satisfaction and more psychological distress. Results from the moderation analyses indicated that the direct effect of male partners’ perceived pornography use and relationship trust and the conditional indirect effects of male partners’ perceived pornography use on both relationship satisfaction and psychological distress were contingent on relationship investment. These findings indicated that when male partners’ perceived pornography use is high, women who have low or mean levels of relationship investment have less relationship trust. Finally, our results revealed that the relationship between male partners’ perceived pornography use and relational and psychological outcomes exist regardless of women’s own attitudes toward pornography

17) Relationship of love and marital satisfaction with pornography among married university students in Birjand, Iran (2015) – Excerpts:

This descriptive-correlation study was conducted on 310 married students studying at private and public universities in Birjand, in 2012-2013 academic year using random quota sampling method. It appears that pornography has a negative impact on love and marital satisfaction.

18)  Sexual media use and relational satisfaction in heterosexual couples (2011) – Excerpt:

This study assessed how sexual media use by one or both members of a romantic dyad relates to relationship and sexual satisfaction. A total of 217 heterosexual couples completed an Internet survey that assessed sexual media use, relationship and sexual satisfaction, and demographic variables. Results revealed that a higher frequency of men’s sexual media use related to negative satisfaction in men, while a higher frequency of women’s sexual media use related to positive satisfaction in male partners. Reasons for sexual media use differed by gender

19) Wives’ Experience of Husbands’ Pornography Use and Concomitant Deception as an Attachment Threat in the Adult Pair-Bond Relationship (2009)

Evidence is growing that pornography use can negatively impact attachment trust in the adult pair-bond relationship. Analyses uncovered three attachment-related impacts from husbands’ pornography use and deception: (1) the development of an attachment fault line in the relationship, stemming from perceived attachment infidelity; (2) followed by a widening attachment rift arising from wives’ sense of distance and disconnection from their husbands; (3) culminating in attachment estrangement from a sense of being emotionally and psychologically unsafe in the relationship. Overall, wives reported global mistrust indicative of attachment breakdown.

20)  Men’s leisure and women’s lives: The impact of pornography on women (1999) – Excerpt:

The section of the interview where the women discussed their own current or past relationships with men revealed additional insight into the effect of pornography on such relationships. Fifteen of the women were in, or had been in, relationships with men who rented or bought pornography at least on an occasional basis. Of these 15 women, four expressed strong dislike of their husband’s or partner’s leisure time interest in pornography. It was clear that the husbands’ use of pornography affected the wives’ feeling about themselves, their sexual feelings, and their marital relationships in general

21)  From Bad to Worse? Pornography Consumption, Spousal Religiosity, Gender, and Marital Quality (2016) – Excerpts:

I test the above hypotheses using data from Wave 1 of the Portraits of American Life Study (PALS), which was fielded in 2006. PALS is a nationally representative panel survey with questions focusing on a variety of topics….Looking at bivariate correlations, for the full sample, viewing pornography is negatively associated with overall marital satisfaction, suggesting that those who view pornography more often tend to be less satisfied in their marriage than those who view pornography less often or never

22) Pornography and Marriage (2014) – All bad news, and it’s getting worse. The abstract:

We used data on 20,000 ever-married adults in the General Social Survey to examine the relationship between watching pornographic films and various measures of marital well-being. We found that adults who had watched an X-rated movie in the past year were more likely to be divorced, more likely to have had an extramarital affair, and less likely to report being happy with their marriage or happy overall. We also found that, for men, pornography use reduced the positive relationship between frequency of sex and happiness. Finally, we found that the negative relationship between pornography use and marital well-being has, if anything, grown stronger over time, during a period in which pornography has become both more explicit and more easily available.

23) Exploring actor and partner correlates of sexual satisfaction among married couples (2010) – Excerpt:

Using the Interpersonal Exchange Model of Sexual Satisfaction, we consider how infidelity, pornography consumption, marital satisfaction, sexual frequency, premarital sex, and cohabitation are associated with married couples’ sexual satisfaction. Data from 433 couples are analyzed with structural equation models to determine the contributions. Finally, some evidence suggests that pornography consumption is costly for own and spouse’s sexual satisfaction, especially when pornography is used by only one spouse.

24) Sexually explicit media use and relationship satisfaction a moderating role of emotional intimacy? (2016) – The authors attempt to obfuscate their findings in the abstract by stating that once sexual and relationship variables were “controlled for”, they found no link between between porn use and relationship satisfaction. Reality: The study found significant correlations between porn use and poorer relationship & sexual satisfaction in both males and females. Excerpt from discussion section:

For both men and women, significant, yet modest negative zero-order correlations between SEM use and relationship satisfaction were found, indicating that increased SEM use was associated with lower relationship satisfaction across gender.

25) Sex in America Online: An Exploration of Sex, Marital Status, and Sexual Identity in Internet Sex Seeking and Its Impacts (2008) – Excerpt:

This was an exploratory study of sex and relationship seeking on the Internet, based on a survey of 15,246 respondents in the United States Seventy-five percent of men and 41% of women had intentionally viewed or downloaded porn. Men and gays/lesbians were more likely to access porn or engage in other sex-seeking behaviors online compared with straights or women. A symmetrical relationship was revealed between men and women as a result of viewing pornography, with women reporting more negative consequences, including lowered body image, partner critical of their body, increased pressure to perform acts seen in pornographic films, and less actual sex, while men reported being more critical of their partners’ body and less interested in actual sex.

  1. […] In the last 20 years research confirms  a tremendous rise in male sexual problems (ED, delayed ejaculation and low sexual desire). ED rates in men under forty have skyrocketed 1,000% or more, while low libido rates have jumped 400%. Several recent studies have found relationships between porn use in young men and ED, anorgamsia, low sexual desire, delayed ejaculation, and lower brain activation to sexual images. In addition, this page contains articles and videos by about 65 experts (urology professors, urologists, psychiatrists, psychologists, sexologists, MDs) who acknowledge and have successfully treated porn-induced ED and porn-induced loss of sexual desire. It must be noted that over 20 neuroscience-based studies on porn users offer support for the concept of porn addiction. […]
