The Structure of Hypersexuality and Its Relation to Impulsivity

Among the multiple controversies surrounding hypersexuality is the important issue of whether it constitutes a univocal construct. Although an initial study supported its homogeneity, more resent research has identified two separate subcomponents-problematic sexuality and sexual drive. The present survey study addressed this issue in a sample that included both in-person tested college students (n = 69) and online respondents (n = 339). A factor analysis of scales attempting to capture the indicators of each subcomponent of hypersexuality yielded two correlated, but separate factors. Whereas Problematic Sexuality (PS) comprised scales measuring sexual compulsivity, using sex as a coping mechanism, and the negative consequences of sexual behavior, Sexual Drive (SD) was defined by frequent sexual activity, preoccupation with sexual fantasies, a predilection for impersonal sexual behavior, and facile sexual arousal. These two subcomponents of hypersexuality were found to covary with different types of impulsivity, further supporting their discrimination and providing external validation for their differentiation. Contrary to a priori hypotheses, however, PS correlated highly with Callous/Manipulative/Risk-Taking as well as with a predicted Affective Instability/Behavioral Disinhibition factor, suggesting that PS may constitute an equifinality of separate developmental trajectories for those high on both subtypes of hypersexuality.

Aripiprazole and its adverse effects in the form of impulsive-compulsive behaviors: A systematic review of case reports

Aripiprazole is an efficacious treatment for both the positive and negative symptoms of schizophrenia and is also commonly used as a mood stabilizer. It is associated with better tolerability compared with other antipsychotics. However, there are reports of patients who experience problem gambling, hypersexuality, obsessive-compulsive symptoms, and other impulsive and/or compulsive behaviors as a result of aripiprazole administration and/or dosage increase. We aimed to do a systematic review of case reports published in this regard. After screening more than 6000 titles and abstracts in ten scientific search engines, we found 35 related records comprising 59 cases. The majority of cases (n = 42, 71.18%) were male, the mean age was 33.83 years (± 13.40), and the average daily dose of aripiprazole was 11.63 mg (± 6.94). The results of our review showed that the most frequently published impulsivity adverse effect of aripiprazole is gambling, followed by hypersexuality, obsessive-compulsive symptoms/disorder, problem eating, trichotillomania, problem shopping, and kleptomania. These symptoms were experienced both by patients who had previous problems in these areas and those who did not. In the majority of cases, the symptoms appeared within 30 days after aripiprazole administration started and ceased within 30 days of its discontinuation and/or dose decrease. Clinicians should be aware of impulsivity adverse effects, monitor them, and educate both patients and the family about them.

Treatment Approaches for Problematic Pornography Use: A Systematic Review

Problematic pornography use (PPU) is an emerging condition associated with several negative psychological and sexual outcomes. This study aimed to systematically review treatment approaches for PPU. Potentially eligible studies were searched for in PubMed/MEDLINE, Embase, PsycINFO, and Web of Science up to April 1, 2023. The quality of the evidence was assessed with the use of the Joanna Briggs Institute's checklists, the Cochrane risk-of-bias tools, and the GRADE approach. A total of 8936 references were retrieved, and 28 studies were included in the systematic review (n = 500 participants). Included studies were case reports (k = 16), case series (k = 1), quasi-experimental investigations (k = 7), and randomized clinical trials (k = 4). The majority of included studies presented overall low quality and significant risk of bias, with all interventions receiving a low or very low rating according to the GRADE approach. Most studies investigated psychological interventions, with the predominance of second and third wave cognitive behavioral therapy interventions. Pharmacological treatments included opioid antagonists (naltrexone in most cases) and antidepressants, while one study investigated a protocol that included rTMS. Several investigations described the combination of psychological and pharmacological approaches. Most studies did not report on side effects, with online and self-help interventions presenting significant issues in terms of treatment adherence. Even though there are promising options that may have efficacy for the treatment of patients with PPU, the literature in the topic still presents significant limitations that compromise the reaching of more definitive conclusions.

Frequency of and Factors Associated with the Presence of a History of Probable Attention-Deficit Hyperactivity Disorder in a Population of Patients with Sex Addiction

INTRODUCTION

Since the first description of sex addiction (SA) by Carnes, research on this problematic behaviour has continued to grow, and the association with attention-deficit hyperactivity disorder (ADHD) appears to be frequent. This study aimed to estimate the frequency of a history of probable ADHD in a population of patients with SA and to explore the factors associated with it.

METHODS

One hundred 85 patients referred to the Nantes University Hospital for SA between 2011 and 2020 were included. Patients completed the Sexual Addiction Screening Test (SAST) or its revised version (SAST-R) to establish the presence of SA. As the SAST-R was not validated in French, we conducted a validation study for the French version. ADHD was screened using the Wender-Utah Rating Scale in childhood and the Adult ADHD Self-Report Scale in adulthood. A multivariate logistic regression model was used to identify factors associated with the presence of a history of probable ADHD.

RESULTS

Childhood ADHD was identified in 36% of patients with SA. Factors associated with the presence of a history of probable ADHD were a low education level, an earlier age of onset of problematic sexual behaviour, another addictive disorder, an anxiety disorder, impulsivity (high negative urgency score), and high scores on harm avoidance and novelty-seeking temperament scales. Furthermore, the French version of the SAST-R displayed good psychometric properties, especially excellent sensitivity.

CONCLUSION

The frequency of a history of probable ADHD among patients with SA is consistent with the literature and close to the highest range. Specific personality traits in patients with both SA and a history of probable ADHD could induce lasting problems of adaptation, which may precipitate the development of SA or maintain it.

The Structure of Compulsive Sexual Behavior: A Network Analysis Study

Compulsive sexual behavior is a phenomenon characterized by a persistent failure to control intense, repetitive sexual impulses or urges, resulting in repetitive sexual behavior that causes marked distress or impairment in personal, familial, social, educational, or occupational areas of functioning. Despite its major impact on mental health and quality of life, little is known about its internal structure and whether this phenomenon differs across genders, age groups, and risk status. By considering a large online sample (n = 3186; 68.3% males), ranging from 14 to 64 years old, compulsive sexual behavior was explored by means of network analysis. State-of-the-art analytical techniques were adopted to investigate the pattern of association among the different elements of compulsive sexual behavior, identify possible communities of nodes, pinpoint the most central nodes, and detect differences between males and females, among different age groups, as well as between individuals at low and high risk of developing a full-blown disorder. The analyses revealed that the network was characterized by three communities, namely Consequence, Preoccupation, and Perceived Dyscontrol, and that the most central node was related to (perceived) impulse dyscontrol. No substantial differences were found between males and females and across age. Failing to meet one's own commitments and responsibilities was more central in individuals at high risk of developing a full-blown disorder than in those at low risk.

Bipolar disorder and sexuality: a preliminary qualitative pilot study

BACKGROUND

Individuals with mental health disorders have a higher risk of sexual problems impacting intimate relations and quality of life. For individuals with bipolar disorder (BD) the mood shifts might to a particular degree affect their sexual function with possible hypersexual interest during manic episodes and low sexual interest during depressive episodes. The diagnosis is often given in late adolescence, which may impact sexual identity and development. Only a few studies have looked at BD and sexual life, with no qualitative research on the topic. We conducted a qualitative pilot study exploring sexuality in connection to mood swings in five participants with BD.

RESULTS

Thematic content analysis revealed five themes: (1) sexual drive and impulses, (2) sexual behavior, (3) thoughts and feelings in relation to sexual issues, (4) intimate relationships, and (5) sexuality and identity. During manic episodes the participants described having a higher sexual drive, leading for some to more sexual interactions. During depressed episodes, the sexual drive in the three female participants was low, however, in the two men, rather than a reduced sexual drive, a more self-destructive way of engaging in sex prevailed. The sexual outgoing behavior during manic phases was described as joyful, with no feelings of shame connected to it. However, the shifts in sexual drive connected to mood shifts affected the participants' relationships negatively. Further, all the participants described having outgoing sexual behavior in their youth.

CONCLUSIONS

Overall, changes in sexual drive may act as a trigger or early warning symptoms of new episodes, pinpointing the clinical relevance of addressing sexuality in individuals with BD. In general, sexual drive followed affective episodes. However, during depressive episodes sex could be, instead of reduced drive, associated with negative feelings. All participants described having an outgoing sexual behavior in their youth before the onset of BD, which might be essential to consider if there is a clinical suspension of BD in an individual.

The Relation of Sexual Attitudes to Hypersexuality and Problematic Pornography Use

Previous studies have shown that specific attitudes related to moral convictions can have an important role in the development and maintenance of problematic sexual behavior symptoms. However, although other types of attitudes, like sexual attitudes, are potentially highly relevant, they have not yet been studied in this role. We investigated how four dimensions of sexual attitudes: Permissiveness, Birth Control, Communion and Instrumentality, contribute to problematic pornography use (PPU) and hypersexual disorder (HD) symptoms, controlling for religiosity, sex, age and relationship status. The study was administered through an online questionnaire and based on a representative sample of n = 1036 (M_age = 43.28, SD = 14.21; 50.3% women) Polish adult citizens. When adjusting for other variables, higher sexual Permissiveness positively predicted HD and PPU among both men (HD: β = .26, p < .001; PPU: β = .22, p < .001) and women (HD: β = .44, p < .001; PPU: β = .26; p < .001). Sexual Instrumentality positively, although weakly, contributed to HD severity among men (β = .11, p < .05). Attitudes reflecting higher support for responsible sexuality (Birth Control subscale) negatively and weakly predicted HD among women (β = - .11, p < .05). Permissiveness was also the only sexual attitude dimension that consistently predicted a higher frequency of sexual activity among men and women. Based on the cutoff criteria proposed by the authors of the used screening instruments (≥ 53 points for the Hypersexual Behavior Inventory and ≥ 4 points for the Brief Pornography Screen), the prevalence of being at risk for HD was 10.0% (men: 11.4%, women: 8.7%) and for PPU was 17.8% (men: 26.8%, women: 9.1%). Our results point to a significant contribution of sexual attitudes to problematic sexual behavior symptoms, which was not encapsulated by the previously studied influence of religious beliefs, although most of the obtained relationships were relatively weak. Particularly, a consistent link between permissive attitudes and both HD and PPU among men and women may indicate that permissive attitudes can potentially contribute to the development and maintenance of problematic sexual behavior. The prevalence of being at risk for PPU (and to some degree HD) in the current representative sample was high. Such results raise questions about the appropriateness of the proposed cutoff criteria and the risk of overpathologizing normative sexual activity, if the cutoff thresholds are not tailored adequately. The results have implications for the assessment, diagnosis and theory of problematic sexual behavior.

An Update on Kleine-Levin Syndrome

Purpose of Review

Kleine-Levin syndrome (KLS) is a rare relapsing-remitting sleep disorder distinguished by recurrent periods of severe hypersomnia accompanied by cognitive, mood, and behavioral changes. This review focuses mainly on the most recent developments and articles concerning this illness in the preceding five years while attempting to provide a basic overview of KLS.

Recent Findings

Genetic links were reported in some patients with KLS, like variation in TRANK1 in a worldwide case-control genome-wide association in patients with KLS, in addition to several uncommon variations in the LMOD3 gene, some of which are likely to be pathogenic, discovered by linkage analysis and exome sequencing in a sizable Saudi Arabian family with KLS and a European cohort of KLS patients. Additionally, recent data indicate that the amplitude of the circadian active/rest cycles significantly decreased during hypersomnia attacks, but during asymptomatic periods, it did not differ significantly from the controls. Moreover, patients with KLS are at a higher risk of developing emerging psychiatric disorders during follow-up. Recent data also points to possible discoveries of diagnostic-potential dysregulated proteomic patterns in KLS. Finally, new data suggest that functional imaging studies are often abnormal in KLS both during and between episodes.

Summary

KLS is an uncommon, severe, and uniform illness. When it comes to the diagnosis and treatment of KLS, these characteristics offer both opportunities and challenges. Over the past five years, some promising work has appeared in genetics, functional imaging, and biomarker identification; nevertheless, these areas still need more focus to advance the detection and treatment of patients suffering from KLS.

Hypersexual behaviour among young adults in Germany: characteristics and personality correlates

BACKGROUND

Hypersexual behaviour (HB) is characterized by recurring unsuccessful efforts to control intense, repetitive sexual impulses that result in sexual activities and manifest in the behaviour of the concerning individual over an extended period. This study aims to describe the characterization of HB among the target group, identify personality correlates, and associations between HB and a lack of sexual education and reflection during school time.

METHODS

A cross-sectional design was used to survey the participants (age 18-27; n = 609) online who were recruited via a web forum for addiction selfcare, a website for casual sex dating, Facebook and the mail distribution of the University of Applied Science Nordhausen (Germany). Standardised questionnaires were used to measure the key variables in the study. The sexual behaviour (masturbation, pornography consumption, promiscuity), several personality tendencies, and retrospective information about sexual education of the participants during school time were investigated. Correlation and binomial logistic regression were used to analyse the data with HB as the outcome variable.

RESULTS

10.5% (n = 64) of the participants were identified as hypersexual. The assignment to male sex, a problematic pornography consumption, and impulsive tendencies were determined as predictors of HB. Strong correlates were identified between HB and promiscuity, and impairments in important areas of life. Weak to moderate correlates comprise between HB and all investigated personality traits, and several aspects of sexual risk behaviour. No association was found between HB and a lacking sexual education during school time. The descriptive analysis revealed further sexual problems within the sample (e.g. feelings of shame and guilt, sexual risk behaviour, sexual dysfunction).

CONCLUSION

Young adults should get more attention as a vulnerable group for the development of hypersexuality in sexual education, prevention and therapy. Regarding to its treatment, HB therefore should be considered together with its associations with sociodemographic information, personality traits, and psychosocial factors.

ADHD prevalence in patients with hypersexuality and paraphilic disorders: a systematic review and meta-analysis

Hypersexuality and paraphilic disorders have been associated with increased ADHD in several studies. To determine the prevalence of ADHD in hypersexuality and paraphilic disorders. Three databases (Medline, Web of Science and Google Scholar) were explored. Using random effects models, we calculated the pooled estimate of ADHD prevalence. The leave-1-out method and subgroup analyses were carried out to identify sources of heterogeneity. Seven studies from three countries (N = 730 patients with hypersexuality) were included (including five US studies). The overall estimate of the prevalence of ADHD in patients with hypersexuality or paraphilic disorders was 22.6% (95% interval: 17-29.4) with high heterogeneity (I² = 63%). No publication bias was observed according to Egger's test. We found no significant difference in ADHD prevalence between the following subgroups: hypersexuality vs. paraphilic disorders, studies exploring the history of childhood ADHD vs. adult ADHD, US studies vs. others. The French study was a source of heterogeneity with a much lower rate than others (4.5%) but did not significantly change the prevalence estimate. Removing this study increases the prevalence to 25%. We found no association between the year of publication and ADHD prevalence. ADHD is much more frequent in populations with hypersexuality or paraphilic disorders compared to the general population. It should be systematically screened. The subgroup analyses were not sufficient to identify all sources of heterogeneity, other sources should be explored in further studies.

Cross-Sectional and Longitudinal Associations Between Posttraumatic Stress Symptoms and Hypersexual Behaviors Among Individuals Who have Gambled in Their Lifetimes

BACKGROUND

Exposure to traumatic experiences represent one factor that may contribute to the development of hypersexual behaviors.

AIM

We investigated the associations between posttraumatic stress symptoms and hypersexual behaviors by analyzing survey data from 2 samples.

METHOD

The first sample consisted of n = 585 college students, and the second consisted of n = 786 adults recruited via Amazon's Mechanical Turk (MTurk), n = 337 of whom completed a 6-month follow-up survey. We conducted 3 hierarchical regression analyses adjusting for age, gender, sexual orientation, impulsivity, drug use, alcohol use, and gambling.

OUTCOMES

The primary outcomes for this investigation were associations between posttraumatic stress symptoms, measured using the PTSD Checklist for DSM-IV and DSM-5 (PCL-C and PCL-5), and hypersexual behaviors, measured using the Hypersexual Behavior Inventory (HBI).

RESULTS

A significant regression, R2 = 0.230, R2adjusted = 0.211, F (14,570) = 12.17, P < .001, revealed posttraumatic stress symptoms were associated with hypersexual behaviors in the university student sample (β = 0.154). A significant regression using the MTurk sample, R2 = 0.403, R2adjusted = 0.392, F (14,771) = 37.13, P < .001, confirmed this finding (β = 0.259). In addition, a significant regression, R2 = 0.562, R2adjusted = 0.541, F (15,321) = 27.42, P < .001, indicated that posttraumatic stress symptoms were longitudinally associated with increased hypersexual behaviors (β = .190) after adjusting for all variables, including baseline hypersexuality.

CLINICAL TRANSLATION

Results suggest that individuals experiencing posttraumatic stress symptoms are at increased risk for current and future hypersexual behaviors.

STRENGTHS & LIMITATIONS

This investigation involved secondary analyses of adults who had gambled at least once in their lives and findings may not generalize to those who have never gambled. Furthermore, longitudinal findings may be impacted by selection bias (42% completion rate) and may not generalize to follow up periods longer than 6-months.

CONCLUSION

This study provides support for the hypothesis that posttraumatic stress symptoms are associated with increased hypersexual behavior, and further research is indicated to explore the etiology and directionality of this relationship. Rosansky JA, Borgogna NC, Kraus SW, et al. Cross-Sectional and Longitudinal Associations Between Posttraumatic Stress Symptoms and Hypersexual Behaviors Among Individuals Who have Gambled in Their Lifetimes. J Sex Med 2022;19:1813-1823.

N-acetylcysteine in the treatment of compulsive sexual behavior disorder: A case series

Although compulsive sexual behavior disorder (CSBD) is a relatively common disorder with an estimated prevalence of at least 3%, clinicians currently have limited evidence and no FDA-approved drugs to guide their treatment of this condition. N-acetylcysteine (NAC), an amino acid that seems to restore extracellular levels of glutamate in the nucleus accumbens, has previously demonstrated efficacy in treating multiple psychiatric disorders, including substance use disorders and putative behavioral addictions. However, no study has assessed the use of NAC (or any other glutamatergic agent, for that matter) in the treatment of CSBD. Here, we present data from a case series of 8 male patients with CSBD treated with NAC in routine clinical practice in a specialty outpatient clinic. Of these 8 patients, all of whom had previously been treated for CSBD with medications, therapy, or both, 5 had marked clinical improvement (&gt;35% improvement on a modified version of Yale-Brown Obsessive Compulsive Scale) on NAC, and 3 showed minimal or no improvement (&lt;15%). These findings suggest that NAC may be a potentially promising, well-tolerated treatment option for patients with CSBD, including those who have failed more traditional therapies.

Hypersexuality as a tip of the iceberg of a primary psychopathology: a joined position statement of the Italian Society of Andrology and Sexual Medicine (SIAMS) and of the Italian Society of Psychopathology (SOPSI)

In the last years, hypersexual behavior has been broadly scientifically studied. The interest in this topic, belonging to psycho-sexology and sexual medicine, has been due to its still unclear aetiology, nature, and its manifestation in relationship with several organic and psychopathological conditions. So, the specialist (the psychologist, psychiatrist, endocrinologist, neurologist) may encounter some difficulties in diagnosing and managing this symptom. The first main objective of this position statement, which has been developed in collaboration between the Italian Society of Andrology and Sexual Medicine (SIAMS) and the Italian Society of Psychopathology (SOPSI) is to give to the reader evidence about the necessity to consider hypersexuality as a symptom related to another underlying condition. Following this consideration, the second main objective is to give specific statements, for the biopsychosocial assessment and the diagnosis of hypersexual behavior, developed on the basis of the most recent literature evidence. To develop a psycho-pharmacological treatment tailored on patients' needs, our suggestion is to assess the presence of specific comorbid psychopathological and organic conditions, and the impact of pharmacological treatments on the presence of an excess of sexual behavior. Finally, a suggestion of a standardized psychometric evaluation of hypersexuality will be given.

Functional Connectivity in Compulsive Sexual Behavior Disorder - Systematic Review of Literature and Study on Heterosexual Males

BACKGROUND

Compulsive Sexual Behavior Disorder (CSBD) was recently included in ICD-11 as a new impulse control disorder. While this certainly improved the diagnosis of CSBD, the underlying brain mechanisms of the disorder are still poorly understood. Better description of brain functional deficits is required.

AIM

Here we investigate patterns of resting-state brain functional connectivity (fc) in a group of CSBD patients compared to a group of healthy controls (HC).

METHODS

A MATLAB toolbox named CONN functional connectivity toolbox was employed to study patterns of brain connectivity. Also correlation between fc and severity of CSBD symptoms and other psychological characteristics, assessed with questionnaires, were examined.

OUTCOMES

We collected resting-state functional magnetic resonance imaging data from 81 heterosexual males: 52 CSBD patients and 29 HC.

RESULTS

We found increased fc between left inferior frontal gyrus and right planum temporale and polare, right and left insula, right Supplementary Motor Cortex (SMA), right parietal operculum, and also between left supramarginal gyrus and right planum polare, and between left orbitofrontal cortex and left insula when compared CSBD and HC. The decreased fc was observed between left middle temporal gyrus and bilateral insula and right parietal operculum. No significant correlations between psychological questionnaires assessing CSBD symptoms and resting-state functional connectivity were observed.

CLINICAL IMPLICATIONS

Results from our study extend the knowledge of brain mechanisms differentiating CSBD from HC.

STRENGTHS & LIMITATIONS

The study was the first large sample study showing 5 distinct functional brain networks differentiating CSBD patients and HC. However, the sample was limited only to heterosexual men, in the future a greater diversity in studied sample and longitudinal studies are needed. Also, the present study examined functional connectivity at the level of regions of interest (ROIs). Future studies could verify these results by examining functional connectivity at the voxel level.

CONCLUSION

The identified functional brain networks differentiate CSBD from HC and provide some support for incentive sensitization as mechanism underlying CSBD symptoms. The correlation between psychological assessment (ie, severity of CSBD, depression and anxiety symptoms, level of impulsivity and compulsivity) and resting-state functional connectivity need further examination.

Orgasm Frequency (Total Sexual Outlet) in a National American Sample

There has been renewed interest in the conceptualization and diagnosis of conditions marked by excessive sexuality. Researchers and clinicians have often utilized orgasm frequency (e.g., total sexual outlet) as an indicator of hypersexuality. Indeed, some have proposed seven or more (7+) orgasms by any means in a typical week as indicating hypersexuality. Most studies utilizing this criterion, however, have examined clinical or judicial samples of men, as opposed to general population samples. The purpose of the current study was to provide representative population data of total sexual outlet (TSO) for people varying in age, relationship status, and sex, while also examining the impact of the phrasing of the questions (i.e., time frame). A total of 1029 participants were recruited online via a Qualtrics panel, consisting of 442 males and 587 females, from diverse regions across the USA. Results indicated that between 10.3 and 16.7% of the sample met the 7+  criterion for hypersexuality, with considerable variation by age, relationship status, sex, and less variation by wording of the question. Results are discussed in terms of the applicability of the 7+ cut-off for identifying elevated TSO. Results from this survey could be useful to researchers and clinicians looking for comparison data for their research and clinical assessment results.

Impulse control disorders, dopamine dysregulation syndrome and sex dysfunction in Parkinson's disease

Hypersexuality (HS), characterized by an aberrant, compulsive and inappropriate sexual drive, is an underreported and undermanaged complication of the treatment with dopamine agonists in patients with Parkinson's disease (PD). HS is part of the spectrum of impulse control disorders (ICDs). The failure to control these addictive behaviors is distressing for the patient and it is associated with important consequences. Reports of the prevalence of HS showed different results, due to the lack of standardized diagnostic criteria, but also due to the embarrassment or guilt feelings that patients experience regarding their sexual behaviors. Overall, it is considered that HS may occur in 1.92-22.8% of PD patients and the main risk factors involved could be male sex and genetic susceptibility. The pathophysiology of HS is unknown, but several degenerative mechanisms were proposed, involving dopaminergic, serotoninergic and noradrenergic pathways in cerebral regions responsive for planning and rewarding. There are no standardized tools for the assessment of HS in PD patients; however, several scales and questionnaires were developed with the aim of screening and rating the severity of ICDs, including HS. The management of HS is challenging. Discontinuation or reducing the dopaminergic treatment was effective in some cases, but it might lead to worsening of the motor function. A multidisciplinary approach is mandatory to manage the other associated aspects, such as psychological and social consequences of HS.

The pathophysiology of sexual dysfunction in Parkinson's disease: An overview

Sexual dysfunction is a common, poorly recognized, poorly discussed (often because of cultural perceptions and sensitivities), bothersome and neglected aspect of the range of non-motor symptoms of Parkinson's disease (PD). The spectrum of sexual dysfunction in PD ranges from hyposexuality-based disturbances to hypersexuality-dominated behaviors in the context of drug-induced impulse control disorder. The pathophysiological mechanisms underlying PD-related sexual dysfunction, specifically for hyposexual disorders, are thus heterogeneous and still not fully understood. However, central and peripheral neural mechanisms secondary to the hallmark pathological alterations of the disease (alpha-synuclein deposition and nigrostriatal degeneration) and to the associated network and neurotransmitter dysfunctions, together with the effects of dopaminergic therapies, seem to play an important role in the development of sexual disturbances. In this chapter, we therefore review the neuroanatomical and neurophysiological basis of sexual function in humans, and we provide insights on the pathophysiological mechanisms of hyposexuality and hypersexuality in PD.

Psychometric Properties of Common Measures of Hypersexuality in an Online Canadian Sample

BACKGROUND

Hypersexuality has been posited as the central defining feature of Compulsive Sexual Behavior Disorder, and although the acceptance and inclusion of this construct in psychiatric nosologies provides some legitimacy, concerns surrounding terminology, assessment, and diagnosis remain.

AIM

The present study was an independent psychometric examination of 2 of the most commonly used measures of Compulsive Sexual Behavior Disorder; specifically, the gender invariance of the latent structure, reliability (test retest, internal consistency), and external correlates (concurrent validity) of these measures.

METHODS

The Sexual Compulsivity Scale and the Hypersexual Behavior Inventory were completed by 2 nonclinical online community samples of cisgender women (ns = 525 and 359), cisgender men (ns = 419 and 364), and transgender or non-binary individuals (ns = 38 and 11).

OUTCOMES

Criterion based measures of sexual history and total sexual outlet (number of orgasms per week) were gathered to validate Sexual Compulsivity Scale and Hypersexual Behavior Inventory total and factor scores.

RESULTS

Results supported the factorial validity of both assessment measures: correlated 3 factor solutions were established through exploratory factor analysis of 1 sample, and confirmatory factor analysis in the second sample. Multiple group confirmatory factor analysis, conducted on the 2 combined samples, also supported the gender invariance of the 3-factor solutions. Additional basic psychometric indices of test-retest and internal consistency reliability and criterion-related (concurrent) validity conducted across the 2 online samples were supported.

CLINICAL IMPLICATIONS

Common measures of hypersexuality have potential for use in its assessment, treatment, and management.

STRENGTHS & LIMITATIONS

Study strengths include: the inclusion of 2 fairly large and diverse online samples, thorough checks for insufficient effort/validity of responding, validity and reliability methodology (ie, measurement at multiple time points, obtaining behavioral indicators of sexual health), and a comprehensive set of psychometric analyses to inform conclusions regarding the external validity, reliability, and latent structure of hypersexuality measures across gender groups. Study limitations include: potential concerns related to validity and accuracy of responding owing to a reliance on self-report, the potential for selection bias, and limiting the examination of the latent structure of hypersexuality to cisgender men and women such that the results may not generalize to gender diverse populations.

CONCLUSION

Hypersexuality is a multidimensional construct, with a common latent structure among cisgender men and women, consistency in measurement over time, and meaningful concurrent associations with behavioral criteria that have relevance for sexual health.

Increase in the Prevalence of Online Pornography Use: Objective Data Analysis from the Period Between 2004 and 2016 in Poland

Despite the considerable amount of attention presently devoted to the high accessibility of online pornography, very little formal analyses have been carried out to show how the advent and proliferation of Internet technology has changed the prevalence of pornography use in populations. We conducted a preliminary analysis based on objective website traffic data, representing the changes in the number of (1) Internet users generally and (2) online pornography users specifically, between 2004 and 2016 in Poland. We observed a clear increase in the estimated number of people using online pornography in the analyzed period. The estimated number of general population members viewing pornography on the Internet increased over three times (310%) between October 2004 and October 2016-starting from an estimated 2.76 million in the first period to 8.54 million in the last. At the same time, we did not observe a clear increase in the percentage of Internet users who viewed online pornography in the same time period. Additionally, pornography viewership on the Internet was almost 2 times more prevalent among male (47%) than female Internet users (27%), and most popular in the 18-27 age group. Since our analysis is based on objective data, it does not share the limitations inherent in self-reports. However, our approach also has several important limitations (e.g., the analysis does not include online activity generated on mobile devices and under a private browsing mode); thus, the results should be interpreted with caution.

Sex Drive as a Possible Mediator of the Gender Difference in the Prevalence of Paraphilic Interests in a Nonclinical Sample

There is a general gender difference in paraphilic interests, such that men report more interest (and greater engagement) in a variety of paraphilic behaviors. Using a nonclinical sample, Dawson et al. (Sexual Abuse, 28(1):20-45, 2016, https://doi.org/10.1177/1079063214525645 ) found that the gender difference in paraphilic interests was eliminated when scores on measures of sex drive were used as mediators. However, their measures of sex drive were about more than just sex drive and included a measure of hypersexuality (i.e., distress, perceived lack of control, and problematic consequences of one's sexuality). This study had two aims: to replicate Dawson et al.'s mediation results (using the same measures and scoring methods), and to discern the effect of sex drive itself (by replacing their measure of hypersexuality with a measure of sex drive). A nonclinical sample of 517 men and 615 women completed an online questionnaire. As expected, men reported less repulsion than women for most paraphilic themes. The gender difference in paraphilic interests was reduced (but not eliminated) both when reproducing Dawson et al.'s analysis and when examining a mediation model focused on sex drive specifically. The same results were obtained when examining the paraphilic interest with the largest gender difference (i.e., voyeurism). A full mediation effect was obtained in an unplanned supplementary analysis using a factor score (derived from eight measures) putatively assessing sex drive. While the main findings are consistent with Dawson et al.'s conclusions that sex drive is a possible mediator, they also suggest that other factors need to be considered to help explain the gender difference in the prevalence of paraphilic interests.

Diagnostic work up: Laboratory and biomarkers

This chapter will focus on the diagnostic work around sexual dysfunction in Parkinson's disease, especially laboratory tests and biomarkers. A number of methods to analyze if sexual dysfunction is caused by neural pathology, vascular dysfunction or other mechanisms are now available. Other methods can be used to differentiate between psychogenic/functional reasons behind sexual dysfunction and organic ones. The role of biomarkers for diagnosis, but also for understanding the reason behind and for counteracting sexual dysfunction is becoming more evident. There is also a rich and increasing number of scales and other instruments available for detecting and quantifying sexual hypo- and hyperactivity. When investigating the reason behind sexual dysfunction in patients with Parkinson's disease comorbidities should also be considered. Finally, early and pronounced sexual dysfunction might in some cases be an indication that differential diagnosis, like Multisystem Atrophy, should be thought about. All these aspects of the diagnostic procedures around sexual dysfunction in Parkinson's disease will be covered in this chapter.

A manless adultery: the story of Bassa as related in a Marcus Valerius Martialis' epigram

During the Golden Age of the Roman Empire, Rome was transformed into a magnificent city where architecture, the arts, and commerce flourished. An inconceivable amount of wealth was accumulated by a handful of noble families, while the masses starved. In such a context, moral values inevitably decline, while sexual mores are liberalized and ever more veer towards salacity. This reality was elegantly illustrated in short, often sarcastic poems known as epigrams. Herein, we present a case of a woman with enigmatic appearance of the external genitalia, exhibiting unrestrained homosexual activity, as described in an epigram by Marcus Valerius Martialis (a contemporary poet who lived in the 1st century AD). Based on the information provided in the ancient text, we formulate a differential diagnosis and deduce that this woman was, in fact, a case of congenital adrenal hyperplasia (CAH). To our knowledge, this is the earliest literary description worldwide of a case of CAH as a cause of homosexuality and unquenchable lust.

Hypersexuality and Impulsivity in Self-Referred Men With Sexual Interest in Minors: Are They Related? Do They Change During Treatment? An Exploratory Pilot Study

Introduction

Studies on characteristics of self-referred men with sexual interest in minors (SIM) and treatment approaches in this group of patients are still relatively rare.

Aim

The aim of this exploratory pilot study was to investigate hypersexuality and impulsivity as 2 dynamic risk factors that could possibly change during treatment in self-referred men with SIM.

Methods

Data were collected at the “Kein Täter Werden (means: not become an offender)” network site in Hamburg. Using self-report questionnaires, the extent of hypersexuality and impulsivity was analyzed with the samples’ pretreatment data via descriptive statistics and compared with nonclinical samples of other studies. The relation between hypersexuality and impulsivity was analyzed via Spearman's correlation coefficient with pretreatment data (N = 77). Intragroup analysis compared hypersexuality and impulsivity from pre- and posttreatment (n = 29).

Main Outcome Measures

Hypersexual Behavior Inventory and Barratt Impulsiveness Scale Version 11.

Results

The degree of generalized impulsivity in the SIM group was comparable to that in nonclinical samples while the degree of hypersexuality was considerably higher than in nonclinical samples. Sixty-four percent of the participants were in the range of clinically relevant hypersexuality. Impulsivity and hypersexuality were weakly positively correlated with each other. During treatment hypersexuality significantly decreased while impulsivity did not differ significantly between before beginning treatment and after (partial) completion.

Conclusion

Hypersexuality, but not impulsivity, was pronounced in the group of self-referred men with SIM and should be targeted in treatment. In order to improve treatment outcome regarding risk reduction in self-referred men with SIM, a focus on treatment approaches that were developed to treat hypersexuality can be expected to be effective while focusing on generalized impulsivity may be less relevant.

What's in a Name? A Phenomenological Exploration of Hypersexuality Narratives

Objective

We explored men's subjective experiences of hypersexuality, including the underlying factors they believed contributed to their sexuality. Methods: We interviewed 32 Canadian men with self-reported concerns related to hypersexuality. Interviews were analyzed using Interpretative Phenomenological Analysis and narrative analysis.

Results

Participants' (hyper)sexual experiences revealed complex histories of desire, life disruptions, and hopes to re-story their sexual lives. Similar (sexual and non-sexual) desires were often attributed to different expressions of hypersexuality.

Conclusion

Assessment and treatment protocols for hypersexuality should account for the social and cultural factors that shape sexuality, and the broader field of desire extending beyond just sexual forms.

Validation and Psychometric Evaluation of the Italian Version of the Bergen-Yale Sex Addiction Scale

Excessive problematic sexual behavior in the form of compulsive sexual behavior disorder (CSBD), hypersexuality (HS), and sex addiction has gained increasing credibility in recent years and has led to the development of various psychometric instruments to assess such behavior. However, there is still considerable controversy over the operational definition of such concepts and whether they can be used interchangeably to describe the behavior. One recently developed tool is the Bergen-Yale Sex Addiction Scale (BYSAS) based on the "components model of addiction." The present study validated the Italian version of the BYSAS. The BYSAS was administered to a large Italian-speaking sample of Italian adults [N = 1230, aged 18 to 67 years] along with psychometric instruments assessing the "Big Five" personality traits, self-esteem, depression, and two other measures of addictive sexual behavior (i.e., PATHOS and Shorter PROMIS Questionnaire-Sex Subscale). Confirmatory factorial analysis supported a one-factor solution. Furthermore, the scale had good internal consistency (Cronbach's α = 0.787). The BYSAS was positively associated with extroversion, openness to experience, depression, and problematic sexual behavior, and negatively associated with self-esteem, conscientiousness, emotional stability, agreeableness, and age. Based on the findings, the BYSAS is a brief, psychometrically reliable and valid measure for assessing sex addiction among Italian adults.

Exploring Hypersexuality Pathways From Eye Movements: The Role of (Sexual) Impulsivity

BACKGROUND

Impulsivity is regarded as a key factor underpinning hypersexuality like-conditions. However, impulsivity is a multifaceted construct, and existing research has not been capturing such complexity, which includes the effects of domain-general and domain-specific impulsivity in hypersexuality.

AIM

The aim of this study was to test the predictive role of specific impulsivity domains, ie, domain-general and domain-specific, in hypersexuality and its associated consequences.

METHODS

Fifty-five men and 58 women went through an emotional Go/-no-Go task (including sexual, high-valence positive, and neutral pictures), aimed at capturing domain-general and domain-specific impulsivity. Ocular metrics were further considered in order to increase the validity of the experimental task, and provide a metric of attention capturing. The study was carried out in a community sample.

OUTCOMES

Self-reported (general)impulsivity and commission errors toward high-valence positive and sexual pictures (signaling domain-general and domain-specific impulsivity, respectively) were settled as independent variables, along with Time to First Fixation to stimuli, capturing early/uncontrolled attention. Scores on hypersexuality and negative consequences emerging from hypersexual behavior were settled as outcome variables.

RESULTS

Self-reported (general)impulsivity was the only predictor of hypersexuality scores, while negative consequences were best accounted by higher fixation time to sexual pictures. In all, findings did not support the role of domain-specific impulsivity (ie, sexual impulsivity) in hypersexuality.

CLINICAL TRANSLATION

Findings tentatively suggest that hypersexuality, as captured at the community level, may be best positioned within the general spectrum of psychopathology, thus influencing educational and clinical intervention protocols aimed at addressing hypersexuality related complaints. Protocols would be expected to primarily target general psychopathology phenomena, rather than specific sexual aspects.

STRENGTHS & LIMITATIONS

This study implemented an innovative approach to capture different impulsivity domains, thus adding to previous literature in the field. However, the current study precludes the generalization of findings to clinical samples, where psychological comorbidities are expected to impact results. Further, findings must be read with caution given to limited effect sizes.

CONCLUSION

While hypersexuality was related to self-reported (general) impulsivity, findings on the negative consequences associated with hypersexual behavior mirrored response patterns found in depression. Such evidence aligns with the assumption that hypersexuality related phenomena might be better positioned in the psychopathology domain, rather than simply framed as a specific sexual problem.

Sexual Inhibition and Sexual Excitation Scales in Men: Psychometric Properties of a Polish Adaptation

The present study aimed to develop a Polish version of the Sexual Inhibition/Sexual Excitation Scale (SIS/SES-PL) and explore its psychometric validity in a sample of 498 men aged between 18 and 55 years. We used exploratory and confirmatory factor analyses to obtain the best model fit. Out of the 45 items in the original scale, 32 items with eight subscales and three higher-order factors: (sexual excitation [SES], sexual inhibition due to performance failure [SIS1], and sexual inhibition due to performance consequences [SIS2]) were included in the SIS/SES-PL. The SIS/SES-PL was found to have a good and satisfactory fit (comparative fit index = .87; Tucker-Lewis Index = .85; root mean square error of approximation = .054; χ² = 1108.7; p < .001; test-retest reliability Cronbach's alpha = .93). A small correlation between age and the SIS1 and SIS2 scores was detected. However, forward multiple regression analysis revealed a significant correlation only between age and SIS1 [β = .23, p < .001, R² for model = .05; F(1, 494) = 27.52, p < .001]. Furthermore, a moderate correlation between SIS1 and SES2, as well as SIS1 and general inhibition properties (measured using the Behavioral Inhibition Scale), was noted. In the case of SIS2, only small effects were observed, with the highest values for engaging in risky sexual behavior. Out of the total number of 42 variables, a moderate correlation between SES and the following was described: importance of sex, hypersexual behaviors, frequency of masturbation, frequency of sexual activities per month, sexual risk-taking, high promiscuity (measured using the Sociosexual Orientation Inventory Revised-Drive), general activation properties (measured using the Behavioral Activation Scale), neuroticism, and erotophilic tendencies (measured using the Sexual Opinion Survey-Short Form). The results of the study allowed us to conclude that the SIS/SES-PL might be a useful tool for tailoring therapy for men with sexual problems, as well as in the field of clinical research on sexual inhibition and excitation. Furthermore, it is a reliable and useful tool for measuring propensities for sexual excitement and inhibition.

The Structure, Covariates, and Etiology of Hypersexuality: Implications for Sexual Offending

PURPOSE OF REVIEW

A substantial increase in research on the structure, covariates, and etiology of hypersexuality has emerged during the last decade. It is the goal of this review to summarize and integrate this research and to indicate some practical implications for clinical and forensic practice, especially as applied to those who have sexually offended.

RECENT FINDINGS

Studies from the last half-decade converge on the conclusion that hypersexuality has both problematic and high sexual drive components. Both aspects have consistently been found to be distributed dimensionally and not categorically. Each subdimension covaries differentially with specific types of impulsivity. In addition to sexual abuse, psychological or emotional abuse has emerged to be a potent developmental antecedent of hypersexuality. Current research has focused on the problematic dimension of hypersexuality and has neglected to specify the criteria for high sexual drive. Lacking are large-scale representative and clinical samples that provide determination of optimal cutoffs for treatment and dispositional decisions for both dimensions of hypersexuality. Research on the etiology of both aspects of hypersexuality is in its infancy, and more differentiated assessments of developmental abuse histories are required.

Hypersexuality in Mixed-Sex Couples: A Dyadic Longitudinal Study

Emotion dysregulation and intimacy problems are theoretically underpinned correlates of hypersexuality (i.e., uncontrollable sexual urges, fantasies, and behaviors resulting in distress and impairment in different areas of functioning), but the directionality of these associations has not been established, as work in this area has relied on cross-sectional designs. Moreover, although hypersexuality may have significant adverse effects on romantic relationships and approximately half of treatment-seeking individuals are in a relationship, prior studies almost exclusively involved samples of men, regardless of their relationship status. The aim of the present study was to examine the directionality of associations between both partners' emotion dysregulation, physical (i.e., partnered sexual frequency) and relationship intimacy, and hypersexuality using a longitudinal, dyadic framework. Self-reported data of 267 mixed-sex couples (M_{age_men} = 29.9 years, SD = 8.2; M_{age_women} = 27.7 years, SD = 6.7) at baseline (T1) and six-month follow-up (T2) were analyzed using a crossed-lagged model within an actor-partner interdependence framework. Prior greater emotion dysregulation (T1) in both men and women was associated with their own later greater hypersexuality (T2). Women's prior greater hypersexuality (T1) was associated with their later lower relationship intimacy (T2). Lower levels of intimacy were not significantly associated with later hypersexuality. No partner effects were found in relation to hypersexuality. Findings suggest that men and women may use sexual behaviors to cope with negative emotions, which could, in turn, lead to hypersexuality. Intimacy problems did not precede hypersexuality, although women's hypersexuality may reduce their own relationship intimacy over time.

Hypersexuality and Trauma: a mediation and moderation model from psychopathology to problematic sexual behavior

INTRODUCTION

. Hypersexuality is a clinical condition regarding the psychopathology of sexual behavior. In this study, we aimed to investigate the role of trauma, through the post-traumatic stress-disorder (PTSD), depression, shame and guilt on the hypersexual behavior.

METHODS

. Through an online platform, a convenience sample of 1025 subjects was recruited (females: n=731; 71.3%; males: 294; 28.7%; age: 29.62±10.90). Recruited subjects compiled a psychometric protocol composed by the Hypersexual Behavior Inventory (HBI) to assess hypersexuality, the International Trauma Questionnaire (ITQ) for PTSD, the Patient Health Questionnaire (PHQ-9) to evaluate depression and the State Shame and Guilt Scale (SSGS) for shame and guilt. Then a mediation/moderation model was performed for the data analysis.

RESULTS

. There was a statistically significant direct effect of post-traumatic symptoms (ITQTotal) on hypersexual behavior (HBTotal). Furthermore, indirect effects were also statistically significant, providing support to the hypothesis that depression and guilt would be serial mediators of trauma-hypersexual behavior relations. The paths through depression and guilt have been found to be the most significant with moderate and high indirect effects on hypersexuality. Moreover, male gender, as covariate variable, is a relevant risk factor for hypersexual behavior.

CONCLUSION

. We found the relationship between hypersexuality and trauma describing a possible etiological pathway mainly involving depression, shame and guilt. Hypersexuality can be considered as a reactive form of a major affective psychopathology representing a tip of the iceberg hiding the real issues of a suffering personality. Clinicians and researchers should therefore consider hypersexual behavior in the light of a symptomatic manifestation of a major psychopathology involving the affective aspects of personality.

Sexual Disorders and Quality of Life in Parkinson's Disease

Introduction

Sexual disorders are the most neglected nonmotor symptoms in Parkinson's disease (PD). Although doctors seek greater priority to motor manifestations, which are the basis for the diagnosis of PD, the nonmotor symptoms deserve to be highlighted as much as the motor problems because of their strong presence and discomfort in the patients, causing the important impairment in the quality of life (QoL) of the individual with PD.

Aim

Provide the prevalence of sexual disorders among patients with PD and alert the medical profession to investigate and be familiar with problems related to QoL and sexual disorders in PD.

Methods

This is a large literature review on sexual disorders in PD and impaired QoL.

Main Outcome Measures

Sexual disorders in PD and prevalence between genders have been described in epidemiological studies. Neuroanatomy, pathophysiology, risk factors, QoL, and etiologies were reviewed.

Results

The estimate of the prevalence of sexual dysfunction in the form of compulsive sexual behavior in PD is higher in men by 5.2% than in women by 0.5%. This diagnosis is a determinant of intense and persistent suffering and is related to several health problems of a social, economic, personal, family, psychological, and occupational nature, which can even culminate in sexual abuse. It is most commonly associated with the use of drugs commonly used in PD therapy in 98.1% of cases. In addition to this serious public health problem, another common condition of sexual dysfunction occur with the decreased libido by loss of the neurotransmitter dopamine proper of the pathophysiology of PD.

Conclusion

The presence of sexual disorders in PD should be tracked and monitored because of its harmful consequences, whether due to increased sexual behavior or associated psychological distress, as well as the impacts on QoL. Early recognition and adequate treatment of PD in its fullness and richness of associated symptoms are essential for improving QoL.

Association of ADHD and hypersexuality and paraphilias

Subjects with ADHD suffer from inattention, hyperactivity, and impulsivity. Clinicians often assume that specific symptoms of ADHD are bound to affect sexual desire by increasing the frequency of hypersexuality. There is a lack of knowledge about the comorbidity between ADHD, hypersexuality, and paraphilias. The aim of this article was to provide a review of the literature on the association of ADHD and hypersexuality and paraphilias and to discuss the screening and the management of these syndromes when associated with ADHD. A systematic review of the literature was performed in PubMed, PsychInfo, and Embase databases. The studies reviewed show that some individuals who suffer from ADHD report hypersexuality and paraphilias, but no clear data emerged supporting the idea that hypersexuality and paraphilias are more frequent in an ADHD population. On the other hand, some studies showed a high prevalence of ADHD in hypersexual and paraphilic subjects. This is the first systematic review of hypersexuality and paraphilias in individuals with ADHD. However, the results are limited by differences in the methodology and measurement instruments for hypersexuality and paraphilias as well as by the small number of studies and the small sample sizes of many studies.

Hypersexuality in neurological diseases: do we see only the tip of the iceberg?

The purpose of this commentary is to investigate the pathophysiological mechanisms underlying hypersexuality and its manifestation in neurological diseases through a meta-analysis. Studies were identified by searching on PubMed, Web of Science and Cochrane databases. All results of each database between 2014 and 2020 were evaluated for possible inclusion. After an accurate revision of complete manuscripts, forty articles satisfied the inclusion/exclusion criteria. Data from our meta-analysis indicated hypersexuality to be a frequent sexual disorder in patients with neurological disorders, especially neurodegenerative ones. Hypersexuality could negatively affect a patient's management and outcomes. This commentary discusses studies that are often incomplete for evaluation measures or sample selection. In our opinion, it is necessary to consider hypersexuality with particular attention, so more extensive sample studies are needed to find the most appropriate treatment to improve the quality of life for both the patient and the caregiver.

The negative consequences of hypersexuality: Revisiting the factor structure of the Hypersexual Behavior Consequences Scale and its correlates in a large, non-clinical sample

Introduction

Despite the growing literature about hypersexuality and its negative consequences, most studies have focused on the risk of sexually transmitted infections (STI’s), resulting in relatively few studies about the nature and the measurement of a broader spectrum of adverse consequences.

Methods

The aim of the present study was to examine the validity and reliability of the Hypersexual Behavior Consequence Scale (HBCS) in a large, non-clinical population (N = 16,935 participants; females = 5854, 34.6%; M_age = 33.6, SD_age = 11.1) and identify its factor structure across genders. The dataset was divided into three independent samples, taking into consideration gender ratio. The validity of the HBCS was investigated in relation to sexuality-related questions (e.g., frequency of pornography use) and the Hypersexual Behavior Inventory (Sample 3).

Results

Both the exploratory (Sample 1) and confirmatory (Sample 2) factor analyses (CFI = 0.954, TLI = 0.948, RMSEA = 0.061 [90% CI = 0.059–0.062]) suggested a first-order, four-factor structure that included work-related problems, personal problems, relationship problems, and risky behavior as a result of hypersexuality. The HBCS showed adequate reliability and demonstrated reasonable associations with the examined theoretically relevant correlates, corroborating the validity of the HBCS.

Conclusion

Findings suggest that the HBCS may be used to assess consequences of hypersexuality. It may also be used in clinical settings to assess the severity of hypersexuality and to map potential areas of impairment, and such information may help guide therapeutic interventions.

Gender-Related Differences in Associations Between Sexual Abuse and Hypersexuality

BACKGROUND

Individuals with histories of sexual abuse may be more likely to experience sexual-related problems including hypersexuality, but gender-related differences remain unclear.

AIM

This online study examined sexual abuse history and hypersexuality by gender among 16,823 Hungarian adults, adjusting for age, sexual orientation, relationship status, education, employment status, and residence.

METHODS

An online questionnaire on one of the largest Hungarian news portals advertised this study examining sexual activities in January 2017. 3 categorizations of age-related sexual abuse were examined: child sexual abuse (CSA) occurring at age 13 and earlier (compared to no abuse), adolescent/adult sexual abuse (AASA; compared to no abuse), and CSA and AASA (CSA/AASA; compared to one age-related category of abuse or the other).

OUTCOMES

The outcome variable, hypersexuality, was examined as a continuous variable due to the low prevalence of clinical hypersexuality in this sample. 3 multivariate linear regression analyses adjusting for covariates aimed to predict hypersexuality from each category of abuse, along with gender and its interaction with each category.

RESULTS

In all models, younger age, non-heterosexual sexual orientation, male gender, single relationship status, less than full-time work, and living in a capital city were associated with hypersexuality, and education was not a significant predictor. CSA, AASA, and CSA/AASA predicted hypersexuality in both men and women. There was a significant interaction between CSA/AASA and gender, such that the relationship between CSA/AASA and hypersexuality was stronger in men than in women.

CLINICAL TRANSLATION

Sexual abuse at each developmental time-point may influence hypersexuality among men and women, although the cumulative impact of CSA and AASA on hypersexuality may be particularly relevant among men.

STRENGTHS & LIMITATIONS

This is one of the largest studies to examine gender-related differences in the relationship between sexual abuse and hypersexuality. Nevertheless, our study is cross-sectional, and longitudinal work is needed to determine how sexual abuse affects children, adolescents, and adults throughout their lives.

CONCLUSION

Developmental impacts of sexual abuse may be considered in a gender-informed fashion in order to develop and optimize effective prevention and treatment strategies for hypersexuality.

Sexual addiction 25 years on: A systematic and methodological review of empirical literature and an agenda for future research

In 1998, Gold and Heffner authored a landmark review in Clinical Psychology Review on the topic of sexual addiction that concluded that sexual addiction, though increasingly popular in mental health settings, was largely based on speculation, with virtually no empirical basis. In the more than two decades since that review, empirical research around compulsive sexual behaviors (which subsumes prior research about sexual addiction) has flourished, ultimately culminating in the inclusion of a novel diagnosis of Compulsive Sexual Behavior Disorder in the eleventh edition of the World Health Organization's International Classification of Diseases. The present work details a systematic review of empirical research published between January 1st, 1995 and August 1st, 2020 related to compulsive sexual behaviors, with a specific focus on evaluating the methodologies of that literature. This review yielded 371 papers detailing 415 individual studies. In general, the present review finds that, although research related to compulsive sexual behaviors has proliferated, much of this work is characterized by simplistic methodological designs, a lack of theoretical integration, and an absence of quality measurement. Moreover, the present review finds a virtual absence of high-quality treatment-related research published within this time frame. Implications of these findings for both clinical practice and future research are discussed.

Sexual Responsivity and the Effects of Negative Mood on Sexual Arousal in Hypersexual Men Who Have Sex With Men (MSM)

BACKGROUND

A number of studies have found that hypersexuality is associated with a high propensity for sexual excitation. In comparison, less is known about the relationship between hypersexuality and sexual arousal at the state level. Also, previous research has revealed a relationship between hypersexuality and negative mood. However, the possibility that sexual response might not be as negatively impacted by negative mood in hypersexual individuals has, as yet, not been tested.

AIM

The purpose of this study was to investigate sexual responsivity and the effects of negative mood on sexual arousal in hypersexual men who have sex with men (MSM).

METHODS

A total of 211 MSM were assigned to a hypersexuality (N = 81) or a control (N = 130) group using an interview patterned with a semi-structured Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders format. Participants filled out questionnaires and were shown neutral, sexual, and anxiety- and sadness-inducing films.

OUTCOMES

Changes in penile circumference and self-reported sexual arousal were the primary outcomes analyzed in this study.

RESULTS

Controlling for age and HIV status, no differences were found in genital response between hypersexual and non-hypersexual men. Also, the 2 groups did not differ in subjective sexual arousal. Moreover, no effects of negative mood were found. Time series clustering analyses revealed 3 groups-low responders and slow and fast high responders. Sexual excitation, but not sexual compulsivity or pornography use, predicted cluster membership.

CLINICAL TRANSLATION

Hypersexual MSM may benefit more from an exploration of motivational and behavioral, as compared to psychophysiological, mechanisms underlying possible links between (negative) mood and sexual behavior.

STRENGTHS & LIMITATIONS

Strengths of the study include its sample size, making it one of the larger psychophysiological sex studies; the use of clinical interviews for group assignment; the inclusion of genital response measures; and the application of time series clustering to examine differences among participants. Limitations include possible sample heterogeneity and the reliance on researcher-selected stimuli.

CONCLUSION

Given the lack of any effects of negative mood on sexual response in hypersexual MSM, future studies could explore in more depth possible motivational and behavioral effects, including, for example, the impact of negative mood on the tendency to seek out sex as a form of distraction or for validation or emotional support.

Pharmacotherapy of Sexual Addiction

PURPOSE OF REVIEW

We reviewed recent data on sexual addiction and its treatment. We examined the different definitions of this disorder, related to the pathophysiological mechanisms. We addressed the pharmacological treatment of sexual addiction.

RECENT FINDINGS

Hypersexual behavior can be considered an addictive disorder. Sexual addiction is accompanied by significant psychiatric and addictive comorbidities and is responsible for life impairment. A comprehensive and efficient treatment must be proposed. Selective serotonin reuptake inhibitors seem the first-line pharmacological treatment for sexual addiction. Naltrexone could be another therapeutic option. Psychotherapy and preferentially cognitive-behavioral therapy should be used in association with pharmacotherapy and treatments of comorbidities.

Peripherally Physiological Responses to External Emotions and Their Transitions in Bipolar I Disorder With and Without Hypersexuality

Hypersexuality is associated with psychiatric disorders such as mania; however, it remains unclear whether bipolar I disorder with (BW) or without (BO) hypersexuality demonstrates different responses to external emotional stimuli and their transitions that were composed of pictures and sounds of same domain. In 21 BW patients, 20 BO patients, and 41 healthy volunteers, we administered polygraph tests (electrocardiogram, electromyogram, electrooculogram, and galvanic skin response) to measure transitions from a primer emotion (i.e., external disgust, erotica, fear, happiness, neutral, and sadness) to a noncongruent emotion (out of the remaining five) and to the primer emotion again (repeat-primer). We also evaluated participants' concurrent states of mania, hypomania, and depression. With neutral as the noncongruent emotion, the heart rate difference in BW was greater than in controls when responses to the primer erotica were subtracted from responses to the repeat-primer erotica, or when to the primer sadness were subtracted from the repeat-primer sadness. The difference of the masseter electromyographic activity in BW was lower than in BO and controls when responses to the noncongruent happiness were subtracted from responses to the repeat-primer neutral, and was lower than in BO when to the noncongruent neutral were subtracted from the repeat-primer erotica. The eyeball movement difference was greater in BW than in BO and controls when responses to the noncongruent sadness were subtracted from responses to the repeat-primer neutral. The heart rate difference when responses to the primer happiness were subtracted from responses to the noncongruent neutral was negatively correlated with mania in BO. BW and BO patients behaved differently to external emotions and their transitions, particularly regarding erotica and sadness, which might characterize unique pathophysiological processes of the two bipolar I disorder subtypes.

Abstinence from Masturbation and Hypersexuality

Despite the lack of evidence for negative health effects of masturbation, abstinence from masturbation is frequently recommended as a strategy to improve one's sexual self-regulation. We adopted a framework of perceived problems with pornography to collect first hints about whether abstinence from masturbation stems from a psychological and behavioral "addiction" or conflicting attitudes. In an online questionnaire survey recruited via a non-thematic Reddit thread (n = 1063), most participants reported that they had tried to be abstinent from masturbation. As visible from zero-order correlations and multiple linear regression, motivation for abstinence was mostly associated with attitudinal correlates, specifically the perception of masturbation as unhealthy. While there were associations with hypersexuality, no significant correlation with behavioral markers such as maximum number of orgasms was found. Higher abstinence motivation was related to a higher perceived impact of masturbation, conservatism, and religiosity and to lower trust in science. We argue that research on abstinence from masturbation can enrich the understanding of whether and how average frequencies of healthy behavior are pathologized.

The Link Between Boredom and Hypersexuality: A Systematic Review

BACKGROUND

Some conceptualizations of hypersexuality posit boredom as a possible trigger of hypersexual behavior.

AIM

This work aims to review published articles addressing the link between boredom and hypersexuality to investigate if this relationship can yet be established based on current empirical data.

METHODS

This systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies, published until September 2019, were retrieved from EBSCO, Scopus, Web of Science, and PubMed. A systematic search was conducted using an exhaustive list of key terms combining "boredom" with "hypersexuality," "sexual impulsivity," "sexual compulsivity," and "sexual addiction." Only articles presenting empirical results concerning the relationship between boredom and hypersexuality were considered.

RESULTS

From the initial poll of 76 articles, only 19 articles were included in our final selection. Of the total studies, 16 were quantitative studies and 3 were qualitative studies. 4 studies were validation studies of hypersexuality-related measures, 11 studies concerned online sexual activity, and 3 reported sexual boredom. 7 studies with men used non-heterosexual samples. 5 studies used samples with both women and men, and 1 study used a sample of women only. Most studies indicate a positive association between boredom and hypersexuality, although 4 did not.

IMPLICATIONS

Further studies with diversified samples are still indispensable, as female samples are not portrayed and research is much focused on online sexual activity. Future research should explore the relationship between boredom and hypersexuality within specific behavioral specifiers including masturbation, pornography use, sexual behavior with consenting adults, cybersex, telephone sex, and strip clubs.

STRENGTHS AND LIMITATIONS

To the authors' knowledge, this is the first review looking at the possible link between boredom and hypersexuality. Investigation on the topic is scarce, and several of the studies included in this review correspond to anecdotal evidences of the phenomenon, as only few studies used appropriate measures of boredom.

CONCLUSION

Although current literature identifies a link between boredom and hypersexuality, further substantive research is still much needed to clarify the associations between the 2 constructs. de Oliveira L, Carvalho J. The Link Between Boredom and Hypersexuality: A Systematic Review. J Sex Med 2020;17:994-1004.

Sexual dysfunction in people with epilepsy

Sexual dysfunction is a common comorbidity in people with epilepsy (PWE) that adversely affects their quality of life. Nearly one-half of men and women with epilepsy have sexual dysfunction, but in the majority, this often goes unnoticed. The wide variation in the reported prevalence of sexual dysfunction in PWE is due to the significant heterogeneity among the studies with regard to patient population, type and severity of epilepsy, number and type of antiseizure drugs (ASDs) used, and the tools used for assessing sexual dysfunction. Generally, patients with uncontrolled epilepsy, longer duration of epilepsy, focal epilepsy, higher seizure frequency, and those receiving enzyme-inducing and multiple ASDs are more likely to have sexual dysfunction. Women generally have dysfunction in the domains of desire, while males usually have arousal disorders such as erectile dysfunction and premature ejaculation. There is limited evidence to indicate that sexual function improves in patients rendered seizure-free following epilepsy surgery. Multiple mechanisms including direct effects of epilepsy, effects of ASDs, and psychosocial factors contribute to sexual dysfunction in epilepsy. Circumstantial evidence indicates that seizures and interictal epileptiform discharges can directly affect the hypothalamic-pituitary axis as well as production of gonadal steroids. Enzyme-inducing ASDs cause sexual dysfunction by affecting the metabolism of gonadal steroids. Limited data suggest that newer ASDs including oxcarbazepine, lamotrigine, and levetiracetam cause no or minimal sexual dysfunction. Depression and anxiety significantly contribute to sexual dysfunction in PWE. A multipronged and multidisciplinary approach is essential for optimizing the sexual functions. Every effort should be made to identify and treat reversible causes including changing to nonenzyme-inducing ASDs and to provide symptomatic relief. Large, prospective studies are required to improve our understanding on prevalence and mechanisms of sexual dysfunction in PWE.

The Relation of Childhood Abuse Experiences to Problematic Sexual Behaviors in Male Youths Who Have Sexually Offended

Psychological abuse and sexual abuse, either alone or in combination, have been implicated as developmental antecedents of problematic sexual thoughts and behaviors in studies of sexually aggressive males (Jesperson, Lalumière, & Seto, 2009; Knight & Sims-Knight, 2011; Levenson & Grady, 2016; Seto & Lalumière, 2010). Recently, psychological abuse perpetrated by a male caregiver has emerged as strongly associated with subsequent hypersexuality in adult males who had sexually offended. In a study of 529 adult male sexual offenders, Kingston, Graham, and Knight (2017) found that male caregiver psychological abuse was the most prominent correlate of hypersexual thoughts and behaviors in adulthood, above and beyond the effects of other abuse types, such as physical abuse and sexual abuse. Consequently, we hypothesized that, among juveniles who had sexually offended, higher self-reported levels of childhood psychological and sexual abuse, in contrast to other types of childhood maltreatment experiences, would covary with higher subsequent levels of normophilic sexualized thoughts and behaviors. Consistent with Kingston et al., Male Caregiver Psychological Abuse accounted for a significant amount of the variance in subsequent reported hypersexuality in this juvenile sample. Furthermore, this factor also emerged as a significant correlate of deviant sexual behaviors and fantasies, such as paraphilic interests and pedophilic preference. Sexual Abuse was also found to be significantly associated with hypersexuality. These findings provide additional support for the demonstrated relation between psychological abuse by a male caregiver and subsequent problematic sexual thoughts and behaviors. These data are also consistent with other research that suggests a gender symmetry effect in the impact of parental discipline and the differential effect of male caregiver abuse on male children.

A Network Approach to Hypersexuality: Insights and Clinical Implications

BACKGROUND

In spite of a growing interest in research on hypersexuality, consensus about its etiology and best treatment strategy has not been achieved.

AIM

To further the empirical and clinical understanding of hypersexuality by exploring the structure of its symptoms using a network analytic approach.

METHODS

In 2014, an online survey advertised as focusing on Internet pornography, sexual health, and relationships was carried out among Croatian men and women aged 18-60 years (M_age = 31.1 years, SD = 9.67). In a sample of 3,028 participants, we applied a network analytic approach to explore the structure of hypersexuality symptoms. In the network, nodes represented hypersexuality symptoms and associated sexual behaviors, while their connections were operationalized as partial correlations. 4 Research questions were addressed: (1) does the hypersexuality network differ between genders; (2) which symptoms are centrally positioned; (3) what is the topological location of pornography use; and (4) are there distinct clusters ("communities") of symptoms in the network?

OUTCOMES

We estimated and plotted hypersexuality networks by gender using items from the Hypersexual Disorder Screening Inventory and the Hypersexual Behavioral Consequences Scale, as well as indicators of sexual desire, pornography use, sexual intercourse, and masturbation frequency.

RESULTS

The structure of the hypersexuality network was surprisingly similar in women and men, both in terms of symptom centrality and the clustering of symptoms. Psychological distress and negative emotions triggered by sexual fantasies and/or behaviors, together with a loss of control over sexual feelings, occupied central positions in the networks. Pornography use was located peripherally in both the men's and women's hypersexuality networks.

CLINICAL TRANSLATION

Psychological distress and negative emotions triggered by sexual fantasies and/or behaviors constituted the core of the hypersexuality network, which makes them potential prime targets for clinical intervention and calls for normalization of (presumably self-stigmatized) sexual expression through affirmative therapy and interventions that enhance self-care, self-compassion, and adaptive coping mechanisms.

STRENGTHS & LIMITATIONS

This is the first network analytic approach to hypersexuality. Apart from its novel insights about the structure of hypersexuality, the study employed several methods to assure reliability and robustness of findings. Considering that networks were estimated in a convenience-based community sample, the findings might not generalize to clinically distressed individuals.

CONCLUSION

Our results demonstrate the usefulness of network analytics to hypersexuality in a non-clinical sample and we encourage future clinical and longitudinal explorations of hypersexuality using this novel approach.

Addressing sexuality and intimacy in people living with Parkinson's during palliative care and at the end of life

Sexuality and intimacy are poorly researched in both people living with Parkinson's and in older people. Triggers for discussion usually centre on sexual dysfunction and hypersexuality in relation to Parkinson's. However, there are many more factors that impact on physical and emotional connectedness. Despite highlighting this unmet need there are limited tools or comprehensive assessments available to help improve quality of life. Further research is required within this field, with emphasis on health professionals' education and on highlighting to patients that they have permission for this topic to be discussed and actioned.

Impulse control disorders in Parkinson's disease: A systematic review on risk factors and pathophysiology

AIM

Purpose of this review is to evaluate the potential risk factors that may predispose to the development of Impulse control disorders (ICDs) in Parkinson's Disease (PD) patients, including the effects of dopaminergic therapy.

METHODS

This descriptive review was conducted to identificate risk factors that could cause impulsive control disorders in PD. Studies were found on PubMed (2010-2018), Web Of Science (January 2010-July 2018) and Cochrane (2010-2018) databases.

RESULTS

The data suggest that intrinsic and extrinsic factors may be involved in the development of behavioral complications. To date, the link between PD and the development of ICDs is not very clear, but studies highlight the existence of a predisposition to ICDs in the presence of risk factors.

CONCLUSIONS

A better assessment of the behavioral disorders of PD may be useful in the rehabilitative intervention for increasing the quality of life.

Quality of life of young adults with non-paraphilic problematic sexual behaviors: An exploratory study

Introduction

Many young adults are unable to control their sexual behavior despite distress or negative consequences created by these activities—a clinical phenomenon described as non-paraphilic problematic sexual behavior (PSB). Little is known about clinical features associated with quality of life in PSB.

Methods

54 participants affected by PSB (ages 18–29 years) were recruited for a study on impulsivity in young adults. PSB was defined as the experience of sexual urges, fantasies, or behaviors that feel overwhelming or out of control. Participants were assessed using the Quality of Life Inventory (QOLI), other validated instruments, and questions examining aspects of health and well-being. Clinical measures associated with variation in quality of life were identified using the statistical technique of partial least squares (PLS).

Results

Lower quality of life in PSB was associated with greater behavioral and self-report measures of impulsivity (specifically, Barratt attentional impulsiveness, lower age at first alcohol use), emotional dysregulation, problematic use of the internet, current suicidality, higher state anxiety and depression, and lower self-esteem.

Conclusions

Impulsivity and affective problems are correlated with lower quality of life in PSB. These associations may provide a means to distinguish PSB from healthy sexual behavior.

•

Quality of life is understudied in adults with problematic sexual behaviors.

•

Lower quality of life was associated with affective problems and impulsivity.

•

Higher quality of life was predicted by better self-esteem.

Understanding the Latent Structure of Hypersexuality: A Taxometric Investigation

We examined the latent structure and taxonicity of hypersexuality in large university and community samples of male and female respondents. Participants completed the Hypersexual Behavior Inventory (HBI) and Sexual Compulsivity Scale (SCS), each as part of larger anonymous online surveys of sexual behavior. Exploratory factor analyses (EFA) were performed in part to prepare the data for taxometric analysis and also to identify the putative dimensions underpinning each measure. Three latent dimensions were identified from each of the Sexual Compulsivity Scale (dyscontrol, consequences, and preoccupation) and Hypersexual Behavior Inventory (coping, dyscontrol, and consequences). Taxometric analyses of the generated factors using mean above minus below a cut (MAMBAC), maximum covariance (MAXCOV), and latent mode factor analysis (L-Mode) broadly supported a dimensional latent structure for hypersexuality, particularly in female participants. Implications pertaining to the assessment of hypersexuality are discussed.

Hypersexuality, Gender, and Sexual Orientation: A Large-Scale Psychometric Survey Study

Criteria for hypersexual disorder (HD) were proposed for consideration in the DSM-5 but ultimately excluded for a variety of reasons. Regardless, research continues to investigate hypersexual behavior (HB). The Hypersexual Behavior Inventory (HBI) is one of the most robust scales assessing HB, but further examination is needed to explore its psychometric properties among different groups. Therefore, the aim of the present study was to examine the generalizability of the HBI in a large, diverse, non-clinical sample (N = 18,034 participants; females = 6132; 34.0%; M_age = 33.6 years, SD_age = 11.1) across both gender and sexual orientation. Measurement invariance testing was carried out to ensure gender- and sexual orientation-based comparisons were meaningful. Results demonstrated when both gender and sexual orientation were considered (i.e., heterosexual males vs. LGBTQ males vs. heterosexual females vs. LGBTQ females), LGBTQ males had significantly higher latent means on the HBI factors. Results also demonstrated LGBTQ males had the highest scores on other possible indicators of hypersexuality (e.g., frequency of masturbation, number of sexual partners, or frequency of pornography viewing). These findings suggest LGBTQ males may be a group most at risk of engaging in hypersexual behavior, and LGBTQ females are at a higher risk of engaging in hypersexual activities due to coping problems. Given the large-scale nature of the study, the findings contribute to the currently growing body of the literature on hypersexuality.
