What factors are associated with reporting lacking interest in sex and how do these vary by gender? Findings from the third British national survey of sexual attitudes and lifestyles

Female Syrian hamster analyses of bremelanotide, a US FDA approved drug for the treatment of female hypoactive sexual desire disorder

Hypoactive sexual desire disorder (HSDD) is the most reported sexual dysfunction among premenopausal women worldwide. Bremelanotide, trade name Vyleesi, has been approved by the United States Food and Drug Administration to treat HSDD. However, despite approval, very little is known about its neurobiological mechanism of action. In this study, we utilized a female Syrian hamster model to investigate the effects of bremelanotide on melanocortin receptor expression in the mesolimbic dopamine system and sexual reward. We found that the majority of melanocortin 3 and 4 (MC4R) receptor mRNA is expressed in dopamine neurons in the ventral tegmental area (VTA). Fewer neurons express MC4R in the nucleus accumbens (NAc) or dorsal striatum, where they rarely colocalize with neurons expressing dopamine D1 or D2 receptors. Instead, MC4R mRNA is expressed in nucleus accumbens interneurons. Neither the low nor the high dose of bremelanotide had an effect on the expression of melanocortin receptor mRNA in the mesolimbic dopamine system. Finally, sexual experience resulted in a conditioned place preference (CPP) in female Syrian hamsters, though bremelanotide treatment failed to enhance sexual reward in this test. The results of this study are discussed in conjunction with similar studies in rats, with the conclusion that bremelanotide does not act on the VTA-NAc reward circuit and does not enhance the rewarding effects of sexual interactions.

Small Effects, Questionable Outcomes: Bremelanotide for Hypoactive Sexual Desire Disorder

Efficacy outcomes are only informative to the extent that they are validated. We examined the measurement properties of efficacy measures from the phase III ("RECONNECT") bremelanotide trials for hypoactive sexual desire disorder (HSDD) in women. Continuous efficacy outcomes, including a) the Female Sexual Function Index (FSFI) and its Desire domain (FSFI-D) and b) the Female Sexual Distress Scale-Desire/Arousal/Orgasm (FSDS-DAO) and its item assessing distress due to low desire (FSDS-DAO #13) have questionable, at best, validity evidence for women with HSDD. We found no validity evidence for previously published categorical treatment response outcomes from the RECONNECT trials. All efficacy results should be reported, but results on 8 of the 11 clinicaltrials.gov-specified efficacy outcomes were heretofore unpublished (including FSDS-DAO total score, FSFI total score, FSFI arousal domain, and items from the Female Sexual Encounter Profile-Revised). We analyzed these outcomes, upon which effect sizes ranged from nil to small. Several other continuous and categorical outcomes generated modest apparent benefits, though nearly all of these outcomes were likely derived post-hoc. Across RECONNECT trial data from two prior publications and the current study, bremelanotide's benefits are statistically modest and limited to outcomes for which scant evidence of validity among women with HSDD exists.

How Do Women and Men Negotiate Sex in Later Life Relationships? A Qualitative Analysis of Data from the English Longitudinal Study of Aging

Later life relationships and in particular the role of sex within them, have often been neglected in research due to assumptions of decline and sexlessness. We contribute to a growing body of work which counters these stereotypes by examining sexual scripts within the socio-cultural context of later life relationships. We analyzed open-text comments from the English Longitudinal Study of Aging (ELSA) collected as part of a self-completion questionnaire. In Wave 6, 1065 participants (M age 67.5, SD 9.6 years) and in Wave 8, 922 participants (M age 69.1, SD 9.01 years) responded to an open-text box question. Across both waves, 38% of respondents were men and 62% were women. The analysis used a coding template developed from existing literature and adjusted to accommodate emerging topics. A gendered analysis of the interrelated topics of relationships, sex and sexuality resulted in themes which illustrate similarities and differences in how men and women negotiate sex in later life relationships. The findings confirm that sex remains integral to intimacy in later life relationships for many men and women. However, they also demonstrate that norms of age and gender interact to shape sex and relationship practices in later life. These norms limit some people's experiences, for example, preventing them from seeking new relationships, as well as creating challenges for intimacy in partnerships. These findings extend the theoretical understanding of relationships and sex in later life.

Association Between Allergic Rhinitis and Asthma in Adults With Loss of Interest in Sex

BACKGROUND

The alterations of sexual desire in allergy respiratory diseases have seldom been analyzed. This paper aims to evaluate the association of allergic rhinitis and asthma among adults with the loss of interest in sex.

METHODS

Through a cross-sectional study, we compared three groups of subjects: one with patients with allergic rhinitis, another with allergic asthma, and a control group. The loss of interest in sex was assessed with the Beck Depression Inventory-II, which includes a scale that evaluates this characteristic.

RESULTS

The prevalence of loss of interest in sex in patients with allergic asthma, allergic rhinitis, and controls was 48.8%, 39.5%, and 20.2%, respectively. In multivariate models, a positive association between a loss of interest in sex and allergic asthma (OR =2.4, p =0.005) and allergic rhinitis (OR =2.1, p =0.03) was found independently. In both models, other associated factors included being female (p <0.001) and living as a couple (p <0.001). In contrast, no significant association was found with age (≥40 years), smoking, alcohol consumption, physical activity, or excess weight.

CONCLUSION

Loss of interest in sex is highly prevalent and is notoriously associated with allergic respiratory diseases; similarly, it is associated with living as a couple and being female.

Living without Partnered Sex in Germany. Results From the First Representative, Population-based German Health and Sexuality Survey (GeSiD)

Broader insights into the life situations of sexually inactive adults in Germany are widely unexplored. Within the nationally-representative survey GeSiD (German Health and Sexuality Survey), undertaken 2018-2019, data of 4,758 participants with lifetime interpersonal sexual experience aged 18-75 years (men: n = 2234; women: n = 2524) were analyzed in regards to partnered sexual inactivity in the past 12 months (PSI; no genital-involving sexual contact with another person). Overall, advanced age, being single and impaired health conditions were associated with PSI. Data showed gender-specific associations with PSI, such as less alcohol, smoking and drug use in women. PSI was associated with lower general life satisfaction throughout different age groups.

Sexual intimacy and relationship happiness in living apart together, cohabiting, and married relationships: evidence from Britain

Research on relationship happiness have traditionally compared cohabiting and married relationships. Studies including LAT relationships are scarce and have disregarded sexual aspects of the relationships. This paper compares how married, cohabitating, and LAT relationships in Britain differ with respect to sexual intimacy (defined as emotional closeness during sex, compatibility in terms of sexual preferences, and interest in having sex with a partner), and relationship happiness. Rich data from the British National Study of Sexual Attitudes and Lifestyles (NATSAL-3, 2010–2012) are used to estimate ordered logistic regression models. Cohabiting individuals share the same levels of sexual intimacy as those married, but they are less happy in their relationship than those married. LAT individuals enjoy overall greater sexual intimacy than coresidential individuals but they are less happy in their relationships. Women in LAT relationships feel less often emotionally close to their partner during sex than married women. By knitting the sex research with the demographic literature, this paper offers new insights in understanding the nature of partnerships, opening up new venues for future research.

Reduced Sexual Desire in Young Norwegian Women: A Mixed-Methods Study

Sexuality has become an area of social competence in which individuals strive to be recognized as sexually competent performers. However, a large proportion of young women experience reduced sexual desire. In this study, both quantitative and qualitative methods were applied. Using data from a questionnaire, the aim of this study was to explore the prevalence of, and the factors associated with, lack of sexual interest and desire among young women in Norway. Further, with the help of in-depth interviews, we investigated how young women with reduced sexual desire experience living with their desire problems and what they experience as the cause of their problems. The sample in the quantitative study consisted of 505 Norwegian women between the ages of 18 and 29 years. ANOVA was employed to explore differences in scores on psychological factors and relational factors, as well as between participants who experienced a lack of sexual interest and desire, and those who did not. The results indicate a high prevalence of lack of sexual interest and desire among women (37.1%), while low appearance satisfaction and low relationship satisfaction were central predictors of lack of sexual interest and desire. The sample in the qualitative study consisted of ten Norwegian women with reduced sexual desire between the ages of 18 and 29 years. Through thematic analysis, four themes emerged as experiences of living with reduced sexual desire: (1) physical and mental health, (2) being a young woman in today's society, (3) relational factors, (4) negative experiences, personal expectations toward sexuality, and sexual trauma.

Effects of Abelmoschus manihot Flower Extract on Enhancing Sexual Arousal and Reproductive Performance in Zebrafish

The flower of Abelmoschus manihot L. is mainly used for the treatment of chronic kidney diseases, and has been reported to have bioactivities such as antioxidant, anti-inflammatory, antiviral, and antidepressant activities. This study used wild-type adult zebrafish as an animal model to elucidate the potential bioactivity of A. manihot flower ethanol extract (AME) in enhancing their sexual and reproductive functions. Zebrafish were fed AME twice a day at doses of 0.2%, 1%, and 10% for 28 days, and were then given the normal feed for an additional 14 days. The hormone 17-β estradiol was used as the positive control. Sexual behavioral parameters such as the number of times males chased female fish, the production of fertilized eggs, and the hatching rate of the fertilized eggs were recorded at days 0.33, 7, 14, 21, 28, and 42. The expression levels of sex-related genes—including lhcgr, ar, cyp19a1a, and cyp19a1b—were also examined. The results showed that the chasing number, fertilized egg production, and hatching rate were all increased with the increase in the AME treatment dose and treatment time. After feeding with 1% and 10% AME for 28 days, the chasing number in the treated group as compared to the control group increased by 1.52 times and 1.64 times, respectively; the yield of fertilized eggs increased by 1.59 times and 2.31 times, respectively; and the hatching rate increased by 1.26 times and 1.69 times, respectively. All three parameters exhibited strong linear correlations with one another (p < 0.001). The expression of all four genes was also upregulated with increasing AME dose and treatment duration. When feeding with 0.2%, 1%, and 10% AME for 28 days, the four sex-related genes were upregulated at ranges of 1.79−2.08-fold, 2.74−3.73-fold, and 3.30−4.66-fold, respectively. Furthermore, the effect of AME was persistent, as the promotion effect continued after the treatment was stopped for at least two weeks. The present findings suggest that AME can enhance the endocrine system and may improve libido and reproductive performance in zebrafish.

The Effect of Mindfulness-Based Cognitive-Behavioral Sex Therapy on Improving Sexual Desire Disorder, Sexual Distress, Sexual Self-Disclosure and Sexual Function in Women: A Randomized Controlled Clinical Trial

Sexual desire disorder is the most common form of sexual dysfunction among women and is associated with problems like sexual distress and reduced sexual self-disclosure. As a result, this RCT study was conducted with 70 reproductive-age women in the form of 4 weekly group educational sessions. Compared to the control group, the mindfulness-based cognitive-behavioral sex therapy (MBCST) intervention significantly improved sexual -desire, -distress, self-disclosure and -function immediately, 4 and 12 weeks after the educational sessions were completed in the intervention group (p < 0.001). Overall, our findings underscore the significance of the MBCST intervention on improving sexual dysfunction among women.Trial registration number: Iranian registry of clinical trials.

Middle-aged Lebanese women's interpretation of sexual difficulties: a qualitative inquiry

BACKGROUND

The study explores women's perception and experience of sexual difficulties. The need to address the subject was triggered by the scarcity of research that reflects on women's subjective views on sexual difficulties. This is particularly crucial for middle-aged women who frequently experience hormonal and psychosocial changes that may affect their sexual life.

METHODS

Using in-depth individual and focus groups interviews, 52 Lebanese women aged 40-55 years discussed their thoughts, feelings and behaviours concerning sexual difficulties. Women were recruited purposefully from clinical and non-clinical settings to get maximum sampling variation that provided rich information and deep understanding of the subject. Recordings were transcribed verbatim and analysed about the framework analysis. Many strategies were adopted to ensure rigour.

RESULTS

Women's narratives led to four themes: women's inability to communicate sexual desires and concerns; male sexual difficulties; marital conflicts; and sexual difficulties as context-bound. Women's sexual difficulties are driven by double standards and inhibiting sexual socialisation. Once married, many women had very challenging sexual experiences. They were obliged to silently bear their husbands' poor sexual performance to protect their masculinity and thus their social image and identity. Women's narratives also showed that marital conflicts, daily life problems as well as physical and psychological burdens further challenged their sexual wellbeing and contributed to their sexual difficulties.

CONCLUSION

The study makes a unique contribution to voicing women's views and concerns as sexuality is insufficiently researched and reported in Lebanon. It emphasises the multidimensional nature of female sexual difficulties, particularly the gender-based norms that inhibit their sexual selves and profoundly affect their sexual wellbeing and capacity to claim their sexual likes and dislikes. Findings have implications on research and practice to help women prevent and overcome their sexual difficulties.

Dyadic Invariance of the Positive Sexuality Scale in Chilean Heterosexual Couples

Gender differences in sexuality-related dimensions have long been investigated in close relationship research. An important assumption when comparing values across gender in dyadic research is that both partners conceptualize the construct under investigation in the same way. Thus, issues of measurement invariance should be considered when working with dyadic data. The aim of the present study was to test the dyadic invariance of the Positive Sexuality Scale (PSS) to assess an individual’s sense of happiness and fulfillment with his/her sexual expression. The PSS was completed by 166 Chilean heterosexual couples, and measurement invariance was tested using confirmatory factor analysis within a dyadic framework. Configural, metric, scalar, and partial strict measurement invariance were supported for the PSS original one-factor model. No between-partner difference was found in the PSS latent factor mean. The functioning of the PSS and the meaning attributed to positive sexuality were the same for both partners. Hence, variations in the PSS levels between both partners in heterosexual couples can be interpreted as true mean differences rather than measurement artifacts.

Occurrence of Side Effects in Treatment-Resistant Depression: Role of Clinical, Socio-Demographic and Environmental Characteristics

Introduction: Treatment-resistant depression (TRD) is a disabling psychiatric condition characterized by the failure of two antidepressants (ADs). Since the occurrence of side effects (SEs) appears to be one of the main determinants of early discontinuation of pharmacological treatments contributing to a pseudo-resistance, the purpose of this study was to determine the parameters associated with the occurrence of SEs under ADs in a cohort of patients with TRD. Methods: An observational, cross-sectional, multicentre study was carried out using data from the French network of Expert Centers for TRD. For the 108 patients enrolled in the study, the statistical analyses focused on the overall occurrence and on the profile of the SEs (9 categories, 32 items). Results: SEs were influenced by age and sex and were positively associated with the intensity of anxious, depressive and suicidal symptoms, a history of childhood trauma (sexual abuse, emotional abuse and neglect), and negatively associated with self-esteem, and assessment of overall functioning. Conclusion: Using variables accessible in common practice, these results fall within the dynamic of a more tailored approach to medicine that could allow, through integrated pharmacological management, the continuation of antidepressant treatments, and therefore limit the risk of therapeutic failure.

Pursuit of Harmony: Relational and Individual Predictors of Sexual Passion Expression

Harmonious, obsessive, and inhibited sexual passion comprise the Triadic Model of Sexual Passion. Research has shown that together they play an important role in sexual and relationship satisfaction. Little is known, however, about the factors that predict the likelihood of having these types of passion expression. Using a Mechanical Turk sample of 1414 individuals, we estimated structural equation models to evaluate how relationship factors (i.e., relationship length, sexual desire, sexual drive) and individual factors (i.e., attachment style, childhood abuse, personality) predict the three constructs from the Triadic Model of Sexual Passion. In general, those with higher sexual desire, secure attachment, no childhood abuse, and low impulsivity and shyness were most likely to report optimal sexual passion (higher harmonious, lower inhibited, and lower obsessive sexual passion). By better understanding how these factors predict sexual passion expression, couples may have an increased likelihood of experiencing harmonious sexual passion in their sexual relationships.

Prevalence and Predictors of Sexual Difficulties and Associated Distress Among Partnered, Sexually Active Older Women in Norway, Denmark, Belgium, and Portugal

There has been little comparative, cross-cultural research on sexual difficulties and associated distress, and factors associated with these, among older women. Therefore, the aim of this study was to investigate prevalence rates of sexual difficulties, distress related to these difficulties, and associated sociodemographic, relational, and health factors, among sexually active older women (60-75 years) in committed relationships across four European countries (Norway, Denmark, Belgium, and Portugal). These data could inform us about what differentiates women who do and do not experience distressing sexual difficulties and facilitate the identification of older women who might benefit from clinical interventions as well as the development of new interventions. In total, 1057 women (357 Norwegian; 322 Danish; 237 Belgian; 141 Portuguese) completed a cross-sectional questionnaire assessing six sexual difficulties-vaginal dryness, orgasmic difficulties, lacking interest in sex, lacking enjoyment in sex, pain during sex, and no excitement/arousal during sex-and associated distress. We found a high prevalence of sexual difficulties lasting 3 months or longer in the past year (between 23.5 and 50.2%, depending on the specific difficulty). With the exception of vaginal dryness and pain during sex, however, the majority of women reporting sexual difficulties (50.0% to 86.1%, depending on the specific difficulty) reported no or mild distress. There were relatively few cross-country differences, either in the prevalence of sexual difficulties or related distress. Few sociodemographic or health variables were associated with distressing sexual difficulties, but higher sexual intimacy, higher emotional intimacy, and better mental health were associated with less distress about some sexual difficulties. The findings underline the importance of healthcare professionals asking older women about sexual function and especially associated distress, and suggest that careful attention to the psychological and relationship context of these sexual difficulties is needed, as these could be important targets in the treatment process.

Psychological Treatment of Low Sexual Desire in Women: Protocol for a Randomized, Waitlist-Controlled Trial of Internet-Based Cognitive Behavioral and Mindfulness-Based Treatments

BACKGROUND

Psychological therapies are effective treatments for hypoactive sexual desire dysfunction (HSDD; formerly hypoactive sexual desire disorder), a common sexual dysfunction among women. Access to evidence-based treatments, however, remains difficult. Internet-based interventions are effective for a variety of psychological disorders and may be a promising means to close the treatment gap for HSDD.

OBJECTIVE

This article describes the treatment protocol and study design of a randomized controlled trial, aiming to study the efficacy of cognitive behavioral and mindfulness-based interventions delivered via the internet for women with HSDD to a waitlist control group. Outcomes are sexual desire (primary) and sexual distress (secondary). Additional variables (eg, depression, mindfulness, rumination) will be assessed as potential moderators or mediators of treatment success.

METHODS

A cognitive behavioral and a mindfulness-based self-help intervention for HSDD will be provided online. Overall, 266 women with HSDD will be recruited and assigned either to one of the intervention groups, or to a waitlist control group (2:2:1). Outcome data will be assessed at baseline, at 12 weeks, and at 6 and 12 months after randomization. Intention-to-treat and completer analyses will be conducted.

RESULTS

We expect improvements in sexual desire and sexuality-related distress in both intervention groups compared to the waitlist control. Recruitment has begun in January 2019 and is expected to be completed in August 2021. Results will be published in 2022.

CONCLUSIONS

This study aims to contribute to the improvement and dissemination of psychological treatments for women with HSDD and to clarify whether cognitive behavioral and/or mindfulness-based treatments for HSDD are feasible and effective when delivered via the internet.

Challenging the Standard Model of Sexual Response: Evidence of a Variable Male Sexual Response Cycle

Historically the male sexual response cycle was seen as uniform and used as the standard for women. Recent research has suggested that men's sexual response cycle may vary more than previously thought. We asked 520 sexually active men between the ages of 18-73 to report on their sexual desire and arousal patterns during their last sexual experience. Using a latent class mixture model from retrospective sexual response data, we found five classes of desire and arousal patterns. These patterns were examined for associations with demographics, outcomes during the sexual experience, and outcomes for the global relationship. The experiences of arousal and desire appear to be indistinguishable for men in this sample. The Fluctuation sexual response class (19% of men) and the High sexual response class (40%) were significantly different from most of the other classes in duration of their sexual experiences and overall satisfaction with their sexual experiences. Still, most sexual response patterns were associated with healthy relational and sexual outcomes. Variability in the male sexual response cycle is important to acknowledge and normalize.

Trends in reported male sexual dysfunction over the past decade: an evolving landscape

We investigated changes in patterns of reported male SDs at a single academic centre over a 10-year time frame. Comprehensive data of 2013 patients consecutively assessed for the first time by a single Sexual Medicine expert between 2006 and 2019 has been analysed. All patients were assessed with a thorough sexual and medical history. Primary reason for seeking medical help at first assessment was recorded for all patients and categorized as: erectile dysfunction (ED), premature ejaculation (PE), low/reduced sexual desire/interest (LSD/I), Peyronie's disease (PD), and other SDs. Linear and logistic regression models tested the association between different reasons for seeking medical help and the time at first evaluation. Local polynomial regression model explored the probability of reporting different SDs over the analysed time frame. Median (IQR) age at first clinical assessment was 50 (38-61) years. Overall, most patients were assessed for ED (824; 41%), followed by PD (369; 18%), PE (322; 16%), LSD/I (204; 10%) and other SDs (294; 15%). Significant changes in terms of reported SD over the analysed time frame were observed. The likelihood of assessing patients for ED significantly increased up to 2013, with a decrease in the past 5 years (p < 0.001). PE assessment at presentation linearly decreased over time (OR: 0.94; 95% CI: 0.91-0.96; p < 0.001). Patients assessed during the past few years were more likely to report PD (OR: 1.20; 95% CI: 1.15-1.25; p < 0.001) and LSD/I (OR: 1.21; 95% CI: 1.16-1.26; p < 0.001), with a linear increase over the evaluated time frame. Likewise, patients were also more likely to report other SDs (Coeff: 1.06; 95% CI: 1.02-1.10; p = 0.004), with a linear increase over time. These results may reflect real changes in SD incidence, increased public awareness towards different SDs and the possible impact of novel treatments available on the market throughout the same time frame.

Predictors and correlates of sexual avoidance among partnered older adults among Norway, Denmark, Belgium, and Portugal

Research on sex in later life has been concerned with documenting that older people continue to have sex and establishing the links between good health and sexual activity. Although sexual avoidance is common in clinical and nonclinical populations of older adults, little attention has been given to the motives for sexual avoidance. To address gaps in the literature on sexual avoidance, the present study explored the self-reported reasons for, and correlates of, sexual avoidance in older partnered individuals with probability samples of 60-75-year-olds in four European countries (Norway, Denmark, Belgium, and Portugal). Results revealed significant differences between men and women in sexual avoidance, with women reporting more avoidance than men. The main reasons reported for avoiding sex were sexual difficulties, health problems, partner's sexual difficulties, and lack of sexual interest. Among men, significant predictors of sexual avoidance were age, relationship intimacy (the only relational predictor), physical health, and own and partner's sexual problems. In women, significant predictors of sexual avoidance were age, relationship duration, relationship satisfaction, relationship intimacy, physical and mental health, and own and partner's sexual problems. Thus, in men, health-related factors were more important predictors of sexual avoidance than relationship factors. In women, relationship factors were as important as health-related factors. These findings provide insight into an under-researched area. They also have important implications for health care and could inform the development of tailored sexual health interventions in older adults.

Trends in Frequency of Sexual Activity and Number of Sexual Partners Among Adults Aged 18 to 44 Years in the US, 2000-2018

IMPORTANCE

Sexual relationships are important for well-being and health. Recent trends in sexual activity among US adults are unknown.

OBJECTIVES

To examine trends in reported frequency of sexual activity and number of sexual partners by sex and age and the association between measures of sexual activity and sociodemographic variables.

DESIGN, SETTING, AND PARTICIPANTS

In this survey study, repeat, cross-sectional analyses of participants aged 18 to 44 years from 10 rounds of the General Social Survey (2000-2018), a US nationally representative survey, were performed for men and women separately.

MAIN OUTCOMES AND MEASURES

Sexual frequency in the past year (sexual inactivity, once or twice per year, 1-3 times per month, or weekly or more) and number of sexual partners in the past year (0, 1, 2, or ≥3 partners). The association between measures of sexual activity and sociodemographic variables were assessed using logistic regression.

RESULTS

The study population included 4291 men and 5213 women in the analysis of sexual frequency and 4372 men and 5377 women in the analysis of number of sexual partners (mean [SD] age, 31.4 [7.6] years; survey response rate, 59.5%-71.4%). Between 2000-2002 and 2016-2018, the proportion of 18- to 24-year-old individuals who reported having had no sexual activity in the past year increased among men (18.9% vs 30.9%; age-adjusted odds ratio [aOR] for trend across survey periods, 1.20; 95% CI, 1.04-1.39) but not among women (15.1% vs 19.1%; aOR for trend, 1.03; 95% CI, 0.89-1.18). Smaller absolute increases in sexual inactivity were observed among those aged 25 to 34 years for both men (7.0% vs 14.1%; aOR for trend, 1.23; 95% CI, 1.07-1.42) and women (7.0% vs 12.6%; aOR for trend, 1.17; 95% CI, 1.01-1.35) but not among those aged 35 to 44 years. The increase in sexual inactivity coincided with decreases in the proportion reporting weekly or more sexual frequency (men aged 18-24 years: 51.8% vs. 37.4%; aOR for trend, 0.88 [95% CI, 0.79-0.99]; men aged 25-34 years: 65.3% vs 50.3%; aOR for trend, 0.87 [95% CI, 0.81-0.94]; women aged 25-34 years: 66.4% vs. 54.2%; aOR for trend, 0.90 [95% CI, 0.84-0.96]) or 1 sexual partner (men aged 18-24 years: 44.2% vs. 30.0%; aOR for trend, 0.88 [95% CI, 0.80-0.98]; women aged 25-34 years: 79.6% vs 72.7%; aOR for trend, 0.91 [95% CI, 0.84-0.99]) and occurred mainly among unmarried men (unmarried men aged 18-44 years: 16.2% vs 24.4%; aOR for trend, 1.14 [95% CI, 1.04-1.25]). Among married men and women, weekly or more sexual frequency decreased (men: 71.1 % vs 57.7%; aOR for trend, 0.86 [95% CI, 0.79-0.93]; women: 69.1% vs 60.9%; aOR for trend, 0.92 [95% CI, 0.86-0.99]). Men with lower income (aOR for men with an annual income of ≥$50 000 vs $0-$9999, 0.37 [95% CI, 0.15-0.90]) and with part-time (aOR vs full-time employment, 2.08; 95% CI, 1.48-2.93) and no employment (aOR vs full-time employment, 2.08; 95% CI, 1.48-2.93) were more likely to be sexually inactive, as were men (aOR vs full-time employment, 2.94; 95% CI, 2.06-4.21) and women (aOR vs full-time employment, 2.37; 95% CI, 1.68-3.35) who were students.

CONCLUSIONS AND RELEVANCE

This survey study found that from 2000 to 2018, sexual inactivity increased among US men such that approximately 1 in 3 men aged 18 to 24 years reported no sexual activity in the past year. Sexual inactivity also increased among men and women aged 25 to 34 years. These findings may have implications for public health.

Sexual Inactivity in Methadone Maintenance Treatment Patients

Sexual dysfunction has been extensively studied in methadone maintenance treatment (MMT) patients. However, little data is available regarding sexual inactivity in the MMT patient population. The objectives of this study were to determine the prevalence and putative risk factors for sexual inactivity in the MMT patient population. This cross-sectional study involved 25-71 year old MMT patients recruited from six methadone clinics. Two hundred and seventy-one patients were interviewed for demographic characteristics, comorbidities, concurrent medications used, and sexual activity. The prevalence of sexual inactivity in the MMT population was found to be 47.6%. Increasing age (p < 0.01) and being single/divorced (p < 0.01) were significantly associated with sexual inactivity. In subgroup analysis, increasing age was significantly associated with sexual inactivity in both single/divorced (p < 0.05) and married (p < 0.05) subgroups, while unemployment (p < 0.05) was only significantly associated with sexual inactivity in the earlier subgroup. Our results suggest that sexual inactivity is common in the MMT patient population. The putative risk factors are related to biological and sociocultural factors. Having specific comorbidities or being on certain medications were not correlated with sexual inactivity in the MMT population. Routine assessment of sexual problems is essential, and proper management should be performed for MMT patients.

Attenuation of Deviant Sexual Fantasy across the Lifespan in United States Adult Males

Deviant sexual fantasy is identified as a risk factor for sexual offending, yet no study has examined deviant sexual fantasy across the lifespan in nonoffending adult males. To bridge this gap, this study examined the frequencies of normative and deviant sexual fantasies among 318 nonoffending adult males in the United States. Participants were recruited via Amazon Mechanical Turk™. Participants took two inventories that assessed demographics and types of sexual fantasies. Normality tests, means tests, Kruskal-Wallis 1-way analyses of variance (ANOVAs), binary logistic regressions, and odds ratio post hoc analyses were conducted. Deviant sexual fantasies progressively declined across all three age groups, while normative sexual fantasy did not. Results suggest that deviant sexual fantasy changes across the lifespan. Applicability of the findings to applied settings, such as sexually violent predator evaluations, is discussed. Limitations and future considerations are addressed.

Sexual Desire Changes in Transgender Individuals Upon Initiation of Hormone Treatment: Results From the Longitudinal European Network for the Investigation of Gender Incongruence

INTRODUCTION

Several steps in the transitioning process may affect sexual desire in transgender people. This is often underexposed by those providing gender-affirming care.

AIM

To prospectively assess sexual desire during the first 3 years of hormonal therapy (HT) in transgender people.

METHODS

This prospective cohort study was part of the European Network for the Investigation of Gender Incongruence. At baseline, different psychological questionnaires were administered. Sex steroids were measured at each follow-up visit. Data were analyzed cross-sectionally and prospectively.

MAIN OUTCOME MEASURE

Prospective analysis of total, dyadic (with another person), and solitary (with oneself) sexual desire in 766 participants (401 transgender women [TW], 364 transgender men [TM]) was carried out using the Sexual Desire Inventory (SDI) questionnaire during a 3-year follow-up period, starting at the initiation of HT. Other factors associated with prospective changes were assessed.

RESULTS

In TW, total, dyadic, and solitary SDI scores decreased during the first 3 months of HT. However, after 36 months, total and dyadic SDI scores were higher than baseline scores. Solitary scores after 36 months were comparable with baseline scores. In TM, total, dyadic, and solitary SDI scores increased over the first 3 months, remaining stable thereafter. However, total and dyadic SDI scores after 36 months were comparable with baseline scores, whereas solitary scores remained higher than baseline. Factors associated with a prospective increase in SDI scores included having undergone gonadectomy, no longer experiencing menstrual bleeding or higher gender dysphoria levels at baseline (in TM only).

CLINICAL IMPLICATIONS

This study offers clear data on the time course of sexual desire after starting HT and thereby helps to inform people who want to start HT. Transgender people can be informed that changes in sexual desire after initiating HT are temporary. Over a longer period of time, the current research does not suggest induction of hypoactive sexual disorder in TW or long-term increased sexual desire in TM.

STRENGTH & LIMITATIONS

Strengths include the prospective design of this large multicentric study, the well-defined cohort, controlling for HT, sex steroids, and other factors. Limitations include performing a data lock, the absence of an objective measure of sexual desire, and the timing of laboratory measurements.

CONCLUSION

Gender-affirming HT only induces short-term changes in sexual desire in transgender people. Over a longer period of time, a net increase in dyadic sexual desire in TW receiving feminizing HT and sexual desire scores comparable with baseline in TM receiving virilizing HT, were observed.

Latent class analysis of sexual health markers among men and women participating in a British probability sample survey

BACKGROUND

Despite known associations between different aspects of sexual health, it is not clear how patterning of adverse sexual health varies across the general population. A better understanding should contribute towards more effective problem identification, prevention and treatment. We sought to identify different clusters of sexual health markers in a general population, along with their socio-demographic, health and lifestyle correlates.

METHODS

Data came from men (N = 5113) and women (N = 7019) aged 16-74 who reported partnered sexual activity in the past year in Britain's third National Survey of Sexual Attitudes and Lifestyles, undertaken in 2010-2012. Latent class analysis used 18 self-reported variables relating to adverse sexual health outcomes (STI and unplanned pregnancy, non-volitional sex, and sexual function problems). Correlates included socio-demographics, early debut, alcohol/drug use, depression, and satisfaction/distress with sex life.

RESULTS

Four classes were found for men (labelled Good Sexual Health 83%, Wary Risk-takers 4%, Unwary Risk-takers 4%, Sexual Function Problems 9%); six for women (Good Sexual Health 52%, Wary Risk-takers 2%, Unwary Risk-takers 7%, Low Interest 29%, Sexual Function Problems 7%, Highly Vulnerable 2%). Regardless of gender, Unwary Risk-takers reported lower STI/HIV risk perception and more condomless sex than Wary Risk-takers, but both were more likely to report STI diagnosis than Good Sexual Health classes. Highly Vulnerable women reported abortion, STIs and functional problems, and more sexual coercion than other women. Distinct socio-demographic profiles differentiated higher-risk classes from Good Sexual Health classes, with depression, alcohol/drug use, and early sexual debut widely-shared correlates of higher-risk classes. Females in higher-risk classes, and men with functional problems, evaluated their sex lives more negatively than those with Good Sexual Health.

CONCLUSIONS

A greater prevalence and diversity of poor sexual health appears to exist among women than men in Britain, with more consistent effects on women's subjective sexual well-being. Shared health and lifestyle characteristics of higher-risk groups suggest widespread benefits of upstream interventions. Several groups could benefit from tailored interventions: men and women who underestimate their STI/HIV risk exposure, women distressed by low interest in sex, and women experiencing multiple adverse outcomes. Distinctive socio-demographic profiles should assist with identification and targeting.

Romantic Relationship Conflict Due to the COVID-19 Pandemic and Changes in Intimate and Sexual Behaviors in a Nationally Representative Sample of American Adults

In early 2020, the novel coronavirus 2019 (COVID-19) spread across the United States and mitigation measures drastically affected the daily lives of Americans. In this study, we assessed the association between COVID-related relationship conflict and changes in intimate and sexual behaviors and experiences. Using data from an online nationally representative probability survey of 1,010 American adults in April 2020, we estimated the impact of coronavirus-related relationship conflict on changes in intimate and sexual behaviors among those in any type of romantic or sexual relationship (N_weighted=742). Further, we assessed the association between conflict and experience of orgasm and feeling emotionally close to partner. Among individuals in relationships, 34% reported some degree of conflict with their romantic partners due to the spread of COVID-19 and its related restrictions. Those experiencing frequent coronavirus-related conflict with their partner were significantly more likely to report decreased frequency of several solo and partnered intimate and sexual behaviors compared to those not experiencing any such conflict, exhibiting a dose-response trend among partnered sexual behaviors. Since the spread of coronavirus and associated social distancing measures in the United States, Americans have experienced escalations in conflict in their romantic partnerships, which was associated with changes to their intimate and sexual lives.

Sex-Differentiated Changes in Sexual Desire Predict Marital Dissatisfaction

Sex is critical to marriage. Yet, there are several reasons to expect spouses to experience declines in the desire for sex over time, and the rates of any declines in sexual desire may differ for men and women. We used two multi-wave, longitudinal studies to test whether male and female members of newlywed couples experienced different rates of change in sexual desire, whether any such changes were accentuated by childbirth, and whether any such changes had implications for marital satisfaction. In both studies, spouses provided multiple reports of sexual desire, marital satisfaction, and childbirth. Results demonstrated that women's sexual desire declined more steeply over time than did men's sexual desire, which did not decline on average. Further, childbirth accentuated this sex difference by partially, though not completely, accounting for declines in women's sexual desire but not men's. Finally, declines in women's but not men's sexual desire predicted declines in both partners' marital satisfaction. These effects held controlling depressive symptoms and stress, including stress from parenthood. The current findings offer novel longitudinal evidence for sex-differentiated changes in sexual desire and therefore suggest an important source of marital discord.

Prevalence and types of sexual inactivity in Britain: analyses of national cross-sectional probability survey data

OBJECTIVES

To examine how prevalence and context of sexual inactivity varies across the life-course, assess dissatisfaction with sex life among those who are sexually inactive and identify associations with factors that may represent reasons for sexual inactivity.

DESIGN

Analysis of cross-sectional probability sample survey data.

SETTING

British general population.

PARTICIPANTS

14 623 participants (n men: 6045 unweighted, 7245 weighted), aged 16-74 years, of the third National Survey of Sexual Attitudes and Lifestyles (Natsal-3), undertaken in 2010-2012.

MAIN OUTCOME MEASURES

Sexual inactivity, defined as not reporting oral, vaginal or anal intercourse in the past year and further categorised into those who were sexually inexperienced (had never had sex), single or in a relationship.

RESULTS

Overall, 15.9% (weighted n 1155/7245) of men and 22.2% (1646/7410) of women were sexually inactive (p<0.001). The proportion of sexually inactive individuals who were sexually inexperienced was larger among men than women (26.3% (304/1155) vs 16.3% (268/1646)), while the proportion who were singles was larger among women (49.8% (820/1646) vs 40.4% (467/1155)). Sexual inexperience was the most common type of sexual inactivity in early adulthood, with this declining with age. A minority of those who had sexual experience but were sexually inactive-34.8% (293/842) of men and 23.6% (319/1349) of women-reported being dissatisfied with their sex lives. Associations with sexual inactivity was observed for a range of sociodemographics and sexual behaviours/attitudes, for example, religion, ethnicity, Body mass index, height, employment status and index of multiple deprivation; these associations varied by type of sexual inactivity and gender.

CONCLUSIONS

While sex is important for well-being, a non-negligible proportion of the population at all ages are sexually inactive, yet many are not dissatisfied with their situation, with implications for sex and relationship counselling.

Sexual functioning in 4,418 postmenopausal women participating in UKCTOCS: a qualitative free-text analysis

OBJECTIVE

Sexual well-being can contribute significantly to the overall quality of women's lives. This qualitative study aimed to examine sexual activity, functioning, and satisfaction in a large sample of postmenopausal women from the UK Collaborative Trial of Ovarian Cancer Screening (UKCTOCS) METHODS:: Thematic analysis was used to evaluate the free-text data of the Fallowfield Sexual Activity Questionnaire (FSAQ) completed by UKCTOCS participants at baseline before annual screening.

RESULTS

A total of 24,305 women completed the baseline FSAQ and 4,525 (19%) provided free-text data, with 4,418 comments eligible for analysis. Median age was 64 years; 65% had a partner and 22.5% were sexually active. Four interrelated themes were derived: partner availability, physical and sexual health, mental well-being, and interpersonal relationships. Primary reason for absence of sexual activity was lack of a partner, mainly due to widowhood (n = 1,000). Women discussed how partner's medical condition (27%) or sexual dysfunction (13.5%), their own physical health (18%) or menopause-related symptoms (12.5%), and prescribed medication (7%) affected sexual activity. Impact of low libido in self (16%) or partner (7%), relationship problems (10.5%) or logistics (6%), and perceptions of ageing (9%) were also mentioned. Few (3%) referred to positive sexual experiences or had sought medical help for sexual problems (6%).

CONCLUSIONS

This qualitative analysis explored postmenopausal women's perspective on their sexual functioning. Having an intimate partner and good physical health are key factors for continuation of sexual activity and satisfaction. Further sexual education for healthcare professionals is needed to raise awareness about sexuality and sexual difficulties in later life. : Video Summary: Supplemental Digital Content 1, http://links.lww.com/MENO/A426.

Sexual Functioning in Men With and Without Disabilities: Findings From a Representative Sample of Australian Men

INTRODUCTION

Studies on sexual function in men with disabilities have mainly relied on clinical samples; population-based evidence on this topic is limited.

AIM

The aim of this study was to compare aspects of sexual function between disabled and nondisabled men using a representative sample.

METHODS

We used data from Ten to Men, a national cohort study of Australian men aged 18-55 years. We first compared the prevalence of 15 sexual function-related difficulties in disabled vs non-disabled men. Next, we used Poisson regression to examine associations between disability and sexual function. The main analytic sample had 8,496 men. Weights and adjustments appropriate to the sampling methodology were applied. Models adjusted for potential confounders. Results were reported as prevalence ratios (PRs). P values of < .05 were considered statistically significant.

MAIN OUTCOME MEASURE

Outcomes were 15 individual items from the National Survey of Sexual Attitudes and Lifestyles-Sexual Function, a validated measure of sexual function with items in 3 domains: physio-psychological aspect; relational aspect; and global self-rating (the 16th item on help-seeking was excluded). These were coded as binary variables denoting past-year sexual problems.

RESULTS

Disabled men had higher prevalence of all outcomes than nondisabled men. 25.6% of men with disabilities and 15.1% of nondisabled men experienced at least 2 of 15 difficulties. The most prevalent problems were "orgasmed too early" (43.8% of disabled men, 37.1% of nondisabled men), imbalance of sexual desire between partners (47.6% of disabled men, 39.2% of nondisabled men), and overall sexual dissatisfaction (39.4% of disabled men, 26.7% of nondisabled men). All adjusted PRs were > 1.00 for disability; associations were statistically significant except "partner experienced sexual difficulties" (PR = 1.23; 95% CI = 0.99-1.53; P = .058) and "orgasmed too early" (PR = 1.16; 95% CI = 1.00-1.35; P = .050). "Presence of discomfort/pain" had the largest adjusted PR for disability (PR = 2.77; 95% CI = 1.89-4.06; P < .001).

CLINICAL IMPLICATION

This population-based analysis on the relationship between disability and sexual function contextualizes evidence from clinical studies. Findings suggest that disparities between men with and without disability exist but are not uniform across different aspects of sexual function.

STRENGTHS & LIMITATIONS

Two major strengths of this study are that the sample included a nondisabled reference group and results are generalizable to Australian men. A key limitation is that disability and sexual function measures are self-reported.

CONCLUSION

This study provides a broad foundation of population-based evidence about sexual function in men with disabilities, relative to men without, showing positive associations between disability and 13 of 15 sexual difficulties.

Couples' Sexual Communication and Dimensions of Sexual Function: A Meta-Analysis

Research and clinical data have shown that couples with sexual problems report a lack of sexual communication. However, no published meta-analyses have evaluated the relationship between sexual communication and sexual function. This meta-analysis examines the correlation between couples' sexual communication and dimension of sexual function across 48 studies. Sexual communication was positively associated with sexual desire (r = .16), sexual arousal (r = .21), lubrication (r = .17), orgasm (r = .23), erectile function (r = .19), less pain (r = .12), and overall sexual function (r = .35). The effect sizes for sexual desire (r = .21; r = .12) and orgasm (r = .26; r = .16) were higher for women than for men. For overall sexual function, studies with married participants (r = .47) had a larger effect size than studies with participants with multiple relationship types (r = .31) or than studies with dating participants (r = .11). Effect sizes were larger for studies conducted outside of the United States (r = .39) compared to studies conducted in the United States (r = .12). We discuss the importance of addressing the relationship between sexual communication and sexual function, as well as future directions for research in this area.

Sexual Aging: A Systematic Review of Qualitative Research on the Sexuality and Sexual Health of Older Adults

Negative stereotypes regarding the sex lives of older adults persist, despite sexuality being an important factor that influences the quality of life. We conducted a systematic review of the qualitative literature on the sexuality and sexual health of older adults to address which topics have been researched and the quality of research within this field. We searched PsycINFO, SocINDEX, MEDLINE, and CINAHL for qualitative articles investigating the sexuality of adults aged 60+ years. We analyzed 69 articles using thematic analysis to synthesize their findings. We identified two overarching thematic categories: psychological and relational aspects of sexuality (personal meanings and understandings of sex, couplehood aspects, and sociocultural aspects) and health and sexuality (effects of illness and/or treatment on sexuality, and help-seeking behaviors). Research is needed into male sexual desire and pleasure, culture-specific and sexual/gender identities and their effect on outcomes such as help-seeking behavior and sexual satisfaction, and sexual risk-taking in older adults.

Successful aging, change in sexual interest and sexual satisfaction in couples from four European Countries

Although the importance of sexuality and physical intimacy for well-being of older adults has been recognized, the role of sexuality in successful aging (SA) has been largely neglected. Building on our previous work, here we further validated a three-dimensional model of SA and examined its associations with sexual satisfaction and change in sexual interest among older heterosexual couples (aged 60-75 years). Participants were recruited in a probability-based survey, which was carried out in 2016-2017 in four European countries. Using structural equation modeling of the Actor-Partner Interdependence, we observed significant relationships between SA and sexual satisfaction for both male and female partners across countries. Among women, their retrospectively assessed change in sexual interest over the past 10 years was consistently associated with sexual satisfaction. Partner effects were gender-specific: male partners' SA was significantly related to their female partners' change in sexual interest, which in turn was linked to male partners' sexual satisfaction. The findings point to substantial ties between successful aging and sexuality in older European couples. Taking into account the prevalent stereotypes about old age and sexuality, this study's findings can assist professionals working with aging couples.
