Studies on the characteristics of individuals with hypersexual disorder have been accumulating due to increasing concerns about problematic hypersexual behavior PHB. Currently, relatively little is known about the underlying behavioral and neural mechanisms of sexual desire. Our study aimed to investigate the neural correlates of sexual desire with event-related functional magnetic resonance imaging fMRI. Twenty-three individuals with PHB and 22 age-matched healthy controls were scanned while they passively viewed sexual and nonsexual stimuli. The subjects' levels of sexual desire were assessed in response to each sexual stimulus.

Studies on the characteristics of individuals with hypersexual disorder have been accumulating due to increasing concerns about problematic hypersexual behavior PHB. Currently, relatively little is known about the underlying behavioral and neural mechanisms of sexual desire.

Our study aimed to investigate the neural correlates of sexual desire with event-related functional magnetic resonance imaging fMRI. Twenty-three individuals with PHB and 22 age-matched healthy controls were scanned while they passively viewed sexual and nonsexual stimuli. The subjects' levels of sexual desire were assessed in response to each sexual stimulus. Relative to controls, individuals with PHB experienced more frequent and enhanced sexual desire during exposure to sexual stimuli.

Greater activation was observed in the caudate nucleus, inferior parietal lobe, dorsal anterior cingulate gyrus, thalamus, and dorsolateral prefrontal cortex in the PHB group than in the control group. In addition, the hemodynamic patterns in the activated areas differed between the groups.

Consistent with the findings of brain imaging studies of substance and behavior addiction, individuals with the behavioral characteristics of PHB and enhanced desire exhibited altered activation in the prefrontal cortex and subcortical regions. In conclusion, our results will help to characterize the behaviors and associated neural mechanisms of individuals with PHB.

Problematic hypersexual behavior PHB is defined as the continuous participation in repeated sex acts with no control over excessive sexual compulsivity and behavior despite the awareness of the associated negative outcomes Goodman, ; Carnes, , Those who suffer from PHB can experience extreme difficulties in their family relationships and job performance.

In addition, they are at greater risk for contracting sexually transmitted diseases or experiencing unwanted pregnancies from promiscuous sexual relations Schneider and Schneider, ; Kuzma and Black, Due to its high prevalence and related problems, the associated risks are increasingly recognized in society as the incidence of PHB appears to be growing. Although the seriousness of PHB is now recognized, it was not included in the DSM-5 American Psychiatric Association, Debates are ongoing as to whether hypersexual disorder should be classified as a disease; therefore, there is no consensus on its definition, classification, or diagnostic criteria.

This reflects the difficulties in establishing a clear classification standard due to the lack of objective and empirical studies on the factors related to hypersexuality disorder. Although, the classification of PHB as a disease is still controversial, it has been proposed that excessive sexual activity should be classified as a category of addictive disorders because PHB includes symptoms that are similar to other forms of addiction Goodman, ; Kor et al.

Enhanced desire is strongly related to the clinically relevant aspects of addictive disorders. Imaging studies have shown that the function of brain regions that are involved in desire is altered in those with substance addiction Garavan et al. Behavioral addictions, such as gambling, internet gaming, and sexual behavior, that do not involve the direct intake of drugs also involve a heightened desire that seems to be related to altered functions in relevant brain regions Crockford et al.

Brain imaging studies of desire in substance addiction and behavioral addiction have shown functional changes in the prefrontal cortex PFC and subcortical reward circuits in subjects with these disorders Goldstein and Volkow, In particular, these studies have identified the key involvement of the PFC in addiction, both through its regulation of limbic reward regions and its involvement in the motivational aspects of repetitive substance use and compulsive behavior.

The disrupted functioning of the PFC leads to impairments in response inhibition and salience attribution, such as the attribution of inappropriately excessive salience to an addictive cue, as in substance and addicted behaviors, and a decreased desire for normal rewarding stimuli Goldman-Rakic and Leung, ; Goldstein and Volkow, Consistent with these results, the results of a neuroimaging study on PHBs suggested that individuals with PHBs have greater subjective sexual desire compared to healthy controls and that the enhanced desire is associated with different patterns of neural responses in the dorsal anterior cingulate-ventral striatal-amygdala functional network Voon et al.

These studies provide evidence that heightened desire and the functional abnormalities implicated in desire are also involved in PHB, even though the behavior itself does not induce neurotoxic effects. Unfortunately, the empirical data on sexual desire-associated neural responses in individuals with PHB are insufficient. Previous studies on the brain mechanisms underlying the processing of sexual desire in individuals with PHB have used conventional block paradigms during functional magnetic resonance imaging fMRI and a relatively prolonged exposure to erotic stimuli.

In block designs, the duration of stimulus presentation is prolonged, and the occurrence of continuous stimuli in a block is completely predictable Zarahn et al. Therefore, block designs likely activate areas that are associated with cognitive processes, such as sustained attention, top-down control, and the inhibition of sexual arousal. This could lead to reduced emotional involvement and therefore change the underlying neural activity Schafer et al.

Methodologically, event-related designs are inferior to conventional block designs for detecting activated brain areas, while they are superior for estimating hemodynamic response function Birn et al. Therefore, the objectives of this study were to 1 replicate previous behavioral findings of heightened sexual desire in individuals with PHBs, 2 identify the changes in brain function in regions known to be associated with enhanced desire, and 3 understand the differences in the hemodynamic responses of those brain areas over time in individuals with PHBs by using event-related fMRI.

We hypothesized that individuals with PHBs are more likely to show greater sexual desire compared to healthy controls and that brain regions, such as the PFC and subcortical reward circuits, show altered activity and hemodynamic responses compared to healthy controls.

Approximately 70 potential participants were recruited from treatment facilities for problematic sexual behavior and Sex Addiction Anonymous meetings.

The exclusion criteria were the following: age over 45 or under 18; a serious psychiatric disorder, such as alcohol use disorder, gambling disorder, major depressive disorder, bipolar disorder, or obsessive-compulsive disorder; currently taking medication; a history of serious head injury; homosexuality; a criminal record; or ineligibility for imaging i. The clinicians conducted clinical interviews of all of the potential subjects, and a final group of 23 males who met the inclusion criteria and not the exclusion criteria were selected for the PHB group.

For the control group, 22 participants with demographic characteristics age, gender, education level, and income level that matched the PHB group were selected.

All of the participants provided written informed consents after the contents of the present study were explained to them. All of the participants received financial compensation dollars for their participation. The participants completed a survey containing questions on their demographic characteristics and sexual activities for the previous 6 months and standardized scales, such as the Barratt Impulsiveness Scale Patton et al. The questions on sexual behavior were age of first sexual intercourse and current sexual relationship status.

An exclusive sexual situation was defined as a relationship in which only two individuals engage in sexual intercourse exclusively with each other. A nonexclusive sexual relationship was defined as the maintaining of multiple sexual relationships with several different sexual partners without maintaining any sort of intimacy in the relationship.

The questions on sexual activity-related characteristics included the frequency of sexual intercourse per week, the frequency of masturbation per week, the frequency of viewing pornography per week, and the number of total sexual partners in the past 6 months.

The score ranges from 0 to 20 points, with higher scores indicating more severe sexual addiction. The HBI is comprised of 19 questions, and the score ranges from 19 to A total score of 53 or higher is indicative of a hypersexual disorder. A prestudy was conducted on men with normal sexual functions who did not participate in the fMRI experiment in order to select the sexual and nonsexual stimuli for the fMRI study File S1.

The visual stimuli consisted of 20 photos that were collected from the International Affective Picture System 6 photos; Lang et al. The sexual stimuli consisted of photographs depicting naked women and sexual activity.

In addition, 20 photos that did not induce any sexual desire were chosen as the nonsexual stimuli. They were matched with the sexual stimuli for their level of pleasantness. The nonsexual stimuli displayed highly arousing scenes, such as water sport activities, celebration of a winning victory, and skiing. These stimuli were chosen in order to identify the brain activity that was solely related to sexual desire by ruling out activity that resulted from feelings of pleasantness and general arousal.

For the fMRI experimental paradigm, brief instructions about the experiment were given for 6 s at the beginning of the experiment, which was followed by the random presentation of either sexual or nonsexual stimuli for 5 s each. Each interstimulus interval was 7—13 s average, 10 s to help the participant to return to their baseline state.

To keep the participants focused on the stimuli, they were asked to press the response button when an unexpected target was presented for approximately ms for a total of 12 times during any interval. After completing the fMRI experiment, the participants watched the same stimuli that were presented in the fMRI experiment, and they were required to respond to the following three questions for a psychological assessment. Second, they were required to rate their sexual desire on a five-point Likert scale ranging from 1 least intense to 5 most intense.

Third, the participants' subjective ratings on the dimensions of valence and arousal to each stimulus were determined according to a seven-point Likert scale. The ratings were formulated on two dimensions. Finally, the participants were required to report any other emotions that they experienced besides sexual desire during their exposure to each stimulus.

Image acquisition was performed with a 3. In order to investigate the behavioral and neural responses that were based solely on sexual desire, the imaging and psychological data for the three pictures that induced other emotions, such as disgust, anger, or surprise, other than sexual arousal were excluded from the data analysis.

The frequency of sexual desire was considered the number of stimuli for which each participant experienced sexual desire from among the total 20 sexual stimuli, and the intensity of sexual arousal was the average level of subjective sexual desire for the 20 erotic pictures. In the preprocessing stage, MRI image acquisition was performed in the following order: slice-timing correction for interleaved acquisition, motion correction, and spatial normalization onto a standard template provided by the Montreal Neurological Institute MNI.

Subsequently, the normalized images were smoothed with an 8-mm Gaussian kernel. After completing the preprocessing, design matrices with two conditions sexual condition and nonsexual condition were created for each participant to identify the areas with sexual desire-related activation.

Individual first-level analyses of the comparisons of sexual condition minus nonsexual condition were used for a random effects analysis, and mean images were created for each subject.

One-sample t -tests on the mean images were used to assess the significant group effects in each group in the contrast images created in the individual analyses. Two-sample t -tests were conducted to identify the differences between the two groups for the brain responses in the sexual condition relative to the nonsexual condition.

Additionally, correlational analyses were conducted only in the PHB group to determine the regions of activation that correlated with the severity of hypersexuality according to the SAST-R.

Because the variance of the questionnaire scores might have been too low to reveal more significant correlations in the control group, correlational analyses were not conducted in the control group. P values less than 0. All of the coordinates of the activated voxels are shown as MNI coordinates in Tables 3 , 4. The percent signal change was extracted from the Regions of Interest ROIs based on the results of the between-group and correlation analyses [i.

The ROIs were created by placing a 5-mm sphere around the coordinates reported in Tables 3 , 4. In order to examine the temporal characteristics of the hemodynamic responses, the BOLD signal time course was also extracted from the ROIs during the presentation of each sexual stimulus total of 12 s; 5 s and 7 s thereafter for all of the participants.

The time courses were then averaged across the participants in each group. Of the 20 healthy control subjects, only two reported other emotions besides sexual arousal in response to the three sexual stimuli. One participant in the control group reported that two sexual stimuli among the 20 sexual stimuli induced disgust and anger, while the other participant in the control group rated that one sexual picture induced surprise. The three sexual pictures that induced feelings other than sexual arousal were excluded from the data analysis.

In the between-group analysis, the PHB group exhibited greater activation in the right dorsal anterior cingulate cortex dACC; BA 24 and 32 , bilateral thalami, left caudate nucleus, right DLPFC BA 9, 46 , and right supramarginal gyrus BA 40 relative to the activation in the control group during exposure to sexual stimuli compared with nonsexual stimuli. No brain regions in the control group showed greater activation than in the PHB group. Comparison of brain activation between the two groups PHB group vs.

The present study examined whether there was a difference in the levels of sexual desire between individuals with PHB and healthy controls and, if so, whether this difference was related to functional alterations in the neural substrates of sexual desire in these individuals.

As predicted, the PHB group showed significantly heightened levels of sexual desire and altered activation in the PFC and subcortical areas compared to controls. These results suggested that the functional changes in the neural circuitry that mediates cue-induced desire for sexual behavior were similar to those in response to cue presentation in individuals with substance addiction or behavioral addiction Garavan et al.

The subject who is truly loyal to the Chief Magistrate will neither advise nor submit to arbitrary measures. An Italian Catholic magazine close to the Vatican ignited passionate debate about what many consider a growing social epidemic when it pronounced against cybersex this week. Adultery is adultery, even if it's virtual, according to the editor of Famiglia Cristiana, Italy's largest-circulation weekly news magazine.

A woman from the northern city of Varese wrote to the magazine, asking for moral guidance as she surfed the Web. And you can commit adultery without leaving your home," she wrote in a long letter. In his Conversations with the Priest column, the magazine's editor said there is no difference.

This latest moral missive from the papal city is being shrugged off by some. Stein does concede, however, that cybersex has become a serious problem with an increasing number of his clients. According to the U. A recent study co-authored by Stanford professor Al Cooper and involving 9, Americans estimates that 15 per cent of Internet users, about 2 million people, are "addicted" to pornographic web sites and the lusty conversations steaming up screens in online chat rooms.

It also found that those who use the Internet for sexual purposes were online for an average of 11 hours a week, and that women are just as likely as men to be cruising the Web for sideline action.

The Council was so alarmed by the findings, it has decided to publish them in a new book titled The Dark Side of the Force. Despite headlines and chatter in popular culture witness recent episodes of Law and Order and Ally McBeal about Internet sex in the workplace, discussion about what it's doing to private relationships has only just begun.

But in the meantime, he says, there aren't any clear answers. Cooper and Stein agree that the definition of infidelity depends on what the partners agree they can live with. Stein says he has clients whose partners would rather them indulge in cybersex than phone sex, because they believe the silence makes it less personal.

Cooper says that for many of his clients, cybersex enhances their relationship, preventing sexually transmitted diseases while adding excitement to life, "so the two of them wind up having a greater time together. For others, it destroys the marriage. Coming to some sort of agreement about what's palatable to both partners, however, is easier said than done.

Rob Weiss, clinical director of the Los Angeles-based Sexual Recovery Institute, agrees: "It's infidelity if your partner says it's infidelity. John, a wealthy Toronto businessman, disagrees. He has dabbled in cyber-porn from time to time, and says there's need for disclosure. Someone on the other end might be talking to me.

But I'm not touching. I'm not cheating. I'm just getting my jollies off. Mind you, he was offering this opinion by telephone from a Caribbean resort, where he was vacationing without his wife. And as someone who is skilled in the art of erotic deception, John confides that he doesn't really understand the appeal of cybersex. Wow," he sneers sarcastically. If that's cheating, it's a sorry state of affairs.

Not everyone agrees. PirateQueen, the screen name of a year-old victim of her boyfriend's addiction to hardcore porn and raunchy chat room conversations, recently came looking for advice on the Infidelity.

He says it doesn't mean anything. When we're intimate, I think about his online women and it's as if they're getting in my way. Am I overreacting? The replies flew back fast and furious. It is still sex and it is still cheating. You have just as much right to go to the nearest nightclub, pick up a cute guy, go to a hotel room, and engage in mutual masturbation. There is NO difference!!! Toronto psychiatrist Irvin Wolkoff says our obsession with physical contact misses the point.

And why not? They're so amusing. But the bottom line is that Internet affairs constitute a fundamental betrayal of trust in a relationship even if no bodily fluids are ever exchanged. Wolkoff deals with this very issue in the pilot episode of his new TV show, House Calls, which debuts in the U. He describes a couple in crisis: "[The husband]told this anonymous figure he loved her, he wanted to kiss her. And then he said he wanted push his wife off a tall cliff so he could hear her screaming and know she was suffering all the way down.

But Wolkoff says this frightening death wish was simply an extension of cyberspace's delusional dimension. But for those few precious minutes on the Internet, he was a movie star. He didn't even care who the person on the other end was. He said it was a woman, but it could've have been a pound fry cook from Alabama for all he knew.

He was looking for a brighter fiction. He didn't deserve to feel like a movie star and the person on the other end didn't deserve his affection. The right to trust and affection, Wolkoff tells his clients, can't be earned over the Internet. I've earned the right to engage in sexual activity with my wife because I'm her partner. We're mules under the same yoke pulling the same wagon. Who's that faceless person on the other end of a keyboard? It's a cheat. Or possibly even worse. According to Andre Stein, Internet incest is the latest kink to be discovered in cyberspace.
