Longitudinal associations between women's cycle characteristics and sexual motivation using Flo cycle tracking data.

In the current research, we used data from a sample of 16,327 menstrual cycle tracking app users to examine the association between menstrual cycle characteristics and sexual motivation tracked over 10 months of app use. Guided by past work that finds links between menstrual cycle characteristics related to conception risk and sexual motivation, we found that (a) between-women, shorter (r = - 0.04, p = 0.007), more regular cycles predicted small increases in sexual motivation (r = - 0.04, p = 0.001); (b) within-women, shorter cycles predicted greater sexual motivation that month (r = - 0.04, p < 0.001) and (c) the next month (ßs: - 0.10 to - 0.06, ps < 0.001), but (d) changes in sexual motivation did not reliably precede changes in cycle length (ßs: - 0.01 to 0.02, ps > 0.15). Within-woman analyses also revealed that (e) shorter cycles were followed by more frequent reports of fatigue (ß = - 0.06, p < 0.001), insomnia (ß = - 0.03, p < 0.001), and food cravings (ß = - 0.04, p < 0.001). Together, results suggest that menstrual cycles characteristics and sexual motivation may covary together in ways that reflect changing investments in reproduction. Small effect sizes and lack of experimental control warrant cautious interpretations of results.

Women and men with distressing low sexual desire exhibit sexually dimorphic brain processing.

Distressing low sexual desire, termed Hypoactive Sexual Desire Disorder (HSDD), affects approximately 10% of women and 8% of men. In women, the 'top-down' theory of HSDD describes hyperactivity in higher-level cognitive brain regions, suppressing lower-level emotional/sexual brain areas. However, it is unknown how this neurofunctional disturbance compares to HSDD in men. To investigate this, we employed task-based functional MRI in 32 women and 32 men with HSDD to measure sexual-brain processing during sexual versus non-sexual videos, as well as psychometric questionnaires to assess sexual desire/arousal. We demonstrate that women had greater activation in higher-level and lower-level brain regions, compared to men. Indeed, women who had greater hypothalamic activation in response to sexual videos, reported higher psychometric scores in the evaluative (r = 0.55, P = 0.001), motivational (r = 0.56, P = 0.003), and physiological (r = 0.57, P = 0.0006) domains of sexual desire and arousal after watching the sexual videos in the scanner. By contrast, no similar correlations were observed in men. Taken together, this is the first direct comparison of the neural correlates of distressing low sexual desire between women and men. The data supports the 'top-down' theory of HSDD in women, whereas in men HSDD appears to be associated with different neurofunctional processes.

Long term follow-up on young adults that underwent hypospadias repair through urethral advancement in childhood.

Assess the long-term outcome on cosmetic appearance, voiding, sexual function, and psychological impact of young adults operated by urethral advance (UA) technique in childhood. Patients over 14 years old, who underwent UA hypospadias repair in our centre (2000-2010) were evaluated. All patients presented mid-distal hypospadias with subcoronal or penile meatus and curvature lower than 20°. The cosmetic appearance, urinary and sexual function, body perception and overall satisfaction were assessed through 5 questionnaires. From 2000 to 2010, 143 children underwent UA hypospadias repair. 36 patients between 14 and 27 years were evaluated. The Hypospadias Objective Penile Evaluation (HOPE) showed an average of 8.75 (+/- 0.97), which indicates a good aesthetic result. Voiding dysfunction symptoms were assessed through the American Urological Association Symptom Index (AUASI) where 80.6% had none or mild symptoms and 19.4% had moderate symptoms. Only 11/36 patients were sexually active, according to the International Index of Erectile Function (IIEF-15) scale, none had erectile dysfunction, and their relationships were satisfactory. Assessment of the body perception through the Genital Perception Scale (GPS) was positive or very positive in 88.9% of the patients. However, the perception of their genitals was positive or very positive in 77.8%, there is a negative correlation between the perception of their body and genitals in 13.9% of the patients. Our results indicate that UA technique for hypospadias repair might be a valid option for the correction of mid-distal hypospadias when indicated.

Pleasurable and problematic receptive anal intercourse and diseases of the colon, rectum and anus.

The ability to experience pleasurable sexual activity is important for human health. Receptive anal intercourse (RAI) is a common, though frequently stigmatized, pleasurable sexual activity. Little is known about how diseases of the colon, rectum, and anus and their treatments affect RAI. Engaging in RAI with gastrointestinal disease can be difficult due to the unpredictability of symptoms and treatment-related toxic effects. Patients might experience sphincter hypertonicity, gastrointestinal symptom-specific anxiety, altered pelvic blood flow from structural disorders, decreased sensation from cancer-directed therapies or body image issues from stoma creation. These can result in problematic RAI - encompassing anodyspareunia (painful RAI), arousal dysfunction, orgasm dysfunction and decreased sexual desire. Therapeutic strategies for problematic RAI in patients living with gastrointestinal diseases and/or treatment-related dysfunction include pelvic floor muscle strengthening and stretching, psychological interventions, and restorative devices. Providing health-care professionals with a framework to discuss pleasurable RAI and diagnose problematic RAI can help improve patient outcomes. Normalizing RAI, affirming pleasure from RAI and acknowledging that the gastrointestinal system is involved in sexual pleasure, sexual function and sexual health will help transform the scientific paradigm of sexual health to one that is more just and equitable.

Evidence for the Impact of Stress and Trauma on Sexual Function in Women: Review and Clinical Recommendations.

Stressors occur in a spectrum, ranging from daily hassles to life-threatening experiences, and can significantly impact sexual functioning. Thus, this review summarizes the intricate relationship between trauma spectrum experiences and women's sexual functioning. Biological mechanisms are described to elucidate the physiologic complexity that manifests because of trauma-related experiences. Additionally, both psychological and social implications are discussed. Treatment recommendations for practitioners working with women are discussed, underscoring the importance of adopting a trauma-informed care model.

Sexuality and Infertility.

Infertility diagnoses and treatment can lead to psychological distress and relationship strain. Infertility is commonly associated with disruptions in sexual function and satisfaction among women, in part due to overlapping etiologic factors (eg, comorbid medical conditions). Women and couples with infertility should be screened for sexual problems and provided education on the relationship between infertility and sexuality. Sexual dysfunction in the context of infertility is often best addressed using an interdisciplinary approach. This article provides a summary on the relationship between sexuality and infertility and recommendations for the assessment and management of sexual dysfunction in women with infertility.

Lived Experiences of Sexuality and Sexual Functioning in Males with SCI: A Mixed-Methods Study.

Background: Sexual dysfunction is highly prevalent in males with spinal cord injury (SCI) and has been recognized to be a key recovery priority. Objectives: This cross-sectional, mixed-methods study aimed to investigate the major themes linked to sexual functioning in males with chronic (>1 year) SCI. Methods: Twenty male participants with SCI, aged 25 to 59 years, completed validated questionnaires exploring sexual function/satisfaction and health-related quality of life and a semi-structured interview with an experienced sexual medicine physician. Sex hormone concentrations and metabolic biomarkers, along with body composition and habitual physical activity levels, were assessed. Interview recordings were transcribed and thematic analysis performed using combined COM-B (Capability, Opportunity, Motivation, and Behavior) and biopsychosocial models to identify and organize major contributors and barriers to sexual functioning. Results: Metabolic and hormonal biomarkers largely fell within normal physiological ranges despite reduced sexual functioning reported in our cohort (19/20 participants reported some degree of erectile dysfunction). Qualitative analysis of interview transcripts revealed 24 themes. Adaptability was important for improving sexual satisfaction. Attraction and attentiveness to sex and partners remained stable over time, while the desire for intimacy increased post injury. Sexual social norms, and comparisons to the able-bodied population, provided challenges for sexual activity and partnership. Environmental concerns regarding access to sexual health resources and accessible physical spaces during intimacy were relevant. Mood disorders and general life stressors negatively impacted sexual desire, while physical activity encouraged sexual activity. Conclusion: By considering a holistic view of sexuality in males with SCI, we identified key contributors and barriers to sexual functioning for the cohort studied.

Association between non-penetrative sexual activities and depression in women with vaginismus: a cross-sectional study.

OBJECTIVE: This cross-sectional study aimed to explore the association between non-penetrative sexual activities (NPSA) and depression levels in women diagnosed with vaginismus. METHODS: A cross-sectional retrospective study was conducted between March 2016 and June 2019, after approval by the Firat University Faculty of Medicine ethics committee. Participants comprised married women referred to our female sexual dysfunction outpatient clinic with vaginismus. Diagnosis of vaginismus was established following comprehensive evaluations, including gynecological examination and psychiatric assessment. Sociodemographic data and Beck Depression Inventory (BDI) scores were collected. We compared depression levels between women who engaged in NPSA and those who did not. RESULTS: Of the 75 women with primary vaginismus included in the study, 18 did not engage in any NPSA and 57 engaged in at least one NPSA. The average BDI score of those who engaged in NPSA was significantly lower than those who did not. A negative correlation was found between the number of NPSA engaged in and BDI scores (r = -0.494). CONCLUSIONS: Women with vaginismus had high depression scores, but engaging in NPSA was associated with lower depression levels. The findings suggest that incorporating NPSA into clinical interventions may be beneficial for managing depression in women with vaginismus.

Role of neuroestrogens in the regulation of social behaviors - From social recognition to mating.

In this mini-review, we summarize the brain distribution of aromatase, the enzyme catalyzing the synthesis of estrogens from androgens, and the mechanisms responsible for regulating estrogen production within the brain. Understanding this local synthesis of estrogens by neurons is pivotal as it profoundly influences various facets of social behavior. Neuroestrogen action spans from the initial processing of socially pertinent sensory cues to integrating this information with an individual's internal state, ultimately resulting in the manifestation of either pro-affiliative or - aggressive behaviors. We focus here in particular on aggressive and sexual behavior as the result of correct individual recognition of intruders and potential mates. The data summarized in this review clearly point out the crucial role of locally synthesized estrogens in facilitating rapid adaptation to the social environment in rodents and birds of both sexes. These observations not only shed light on the evolutionary significance but also indicate the potential implications of these findings in the realm of human health, suggesting a compelling avenue for further investigation.

Genital arousal and responsive desire among women with and without sexual interest/arousal disorder symptoms.

BACKGROUND: Models depicting sexual desire as responsive to sexual arousal may be particularly apt for women experiencing arousal or desire difficulties, and the degree to which arousal triggers desire may depend on the relationship context and desire target and timing-yet, these associations have not been directly tested among women with and without sexual interest/arousal disorder (SIAD). AIM: To assess the role of SIAD status and relationship satisfaction in the associations between genital arousal and 4 types of responsive desire. METHODS: One hundred women (n = 27 meeting diagnostic criteria for SIAD) in romantic relationships with men viewed a sexual film (pleasurable intimate depiction of oral sex and penile-vaginal intercourse) while their genital arousal was recorded via vaginal photoplethysmography (n = 63) or thermal imaging of the labia (n = 37). Partner and solitary desire was assessed immediately before and after the film (immediate desire) and 3 days later (delayed desire). OUTCOMES: Outcomes consisted of genital response (z scored by method) and associations between genital response and responsive sexual desire. RESULTS: The key difference between women with and without SIAD was not in their ability to experience genital arousal but in how their genital responses translated to responsive sexual desire. Women with SIAD actually exhibited greater genital arousal than unaffected women. Associations between genital arousal and desire were significant only for women with SIAD and depended on relationship satisfaction and desire type. For women with SIAD with low relationship satisfaction, higher arousal predicted lower immediate desire for a partner; for those with high relationship satisfaction, arousal was either positively related (vaginal photoplethysmography) or unrelated (thermal imaging of the labia) to immediate desire for a partner. Associations with other desire types were not significant. CLINICAL IMPLICATIONS: Patterns of genital arousal and partner-specific responsive desire among women affected with SIAD were indicative of an avoidance model in response to heightened genital arousal, unless relationship satisfaction was high; attending to genital arousal sensations could be a means of triggering sexual desire for women with SIAD who are satisfied in their relationships. STRENGTHS AND LIMITATIONS: This is one of the first sexual psychophysiologic studies to connect relationship factors to patterns of sexual response. The differing arousal assessment procedures and lack of official diagnosis may have attenuated results. The homogeneous sample and in-person session requirement limit generalizability. CONCLUSION: When compared with unaffected women, women affected by SIAD may exhibit stronger arousal responses with sufficiently incentivized sexual stimuli, and the connection between their genital arousal and responsive desire for their partners may be stronger and more dependent on relationship context.

Ovulatory cycle shifts in human motivational prioritisation of sex and food.

Previous research on the endogenous effects of ovarian hormones on motivational states in women has focused on sexual motivation. The Motivational Priority Shifts Hypothesis has a broader scope. It predicts a shift from somatic to reproductive motivation when fertile. In a highly powered preregistered online diary study across 40 days, we tested whether 390 women report such an ovulatory shift in sexual and eating motivation and behaviour. We compared 209 naturally cycling women to 181 women taking hormonal contraceptives (HC) to rule out non-ovulatory changes across the cycle as confounders. We found robust ovulatory decreases in food intake and increases in general sexual desire, in-pair sexual desire and initiation of dyadic sexual behaviour. Extra-pair sexual desire increased mid-cycle, but the effect did not differ significantly in HC women, questioning an ovulatory effect. Descriptively, solitary sexual desire and behaviour, dyadic sexual behaviour, appetite, and satiety showed expected mid-cycle changes that were diminished in HC women, but these failed to reach our strict preregistered significance level. Our results provide insight into current theoretical debates about ovulatory cycle shifts while calling for future research to determine motivational mechanisms behind ovulatory changes in food intake and considering romantic partners' motivational states to explain the occurrence of dyadic sexual behaviour.

Longitudinal changes in sexual desire and attraction among women who started using the Natural Cycles app.

Many women experience sexual side effects, such as decreased libido, when taking hormonal contraceptives (HCs). However, little is known about the extent to which libido recovers after discontinuing HCs, nor about the timeframe in which recovery is expected to occur. Given that HCs suppress the activities of multiple endogenous hormones that regulate both the ovulatory cycle and women's sexual function, resumption of cycles should predict libido recovery. Here, using a combination of repeated and retrospective measures, we examined changes in sexual desire and partner attraction (among partnered women) across a three-month period in a sample of Natural Cycles users (Survey 1: n = 1596; Survey 2: n = 550) who recently discontinued HCs. We also tested whether changes in these outcomes coincided with resumption of the ovulatory cycle and whether they were associated with additional factors related to HC use (e.g., duration of HC use) or relationship characteristics (e.g., relationship length). Results revealed that both sexual desire and partner attraction, on average, increased across three months after beginning to use Natural Cycles. While the prediction that changes in sexual desire would co-occur with cycle resumption was supported, there was also evidence that libido continued to increase even after cycles resumed. Together, these results offer new insights into relationships between HC discontinuation and women's sexual psychology and lay the groundwork for future research exploring the mechanisms underlying these effects.

The role of exogenous testosterone and social environment on the expression of sociosexuality and status-seeking behaviors in young Chilean men.

Testosterone plays an important role as a social hormone. Current evidence suggests that testosterone is positively related to sociosexuality increasing the psychological attitudes toward investing in short-term versus long-term mating and promotes status-seeking behaviors both by dominance and prestige. In addition, the social environment may play an important role in the expression of mating effort through changes in sociosexuality and status-seeking behaviors. However, the causal relationships among the mentioned variables are still debated. We employed a double-blind, placebo-controlled within-individual design, in order to test and integrate the proposed causal relationships between testosterone and social environment over short-term and long-term mating orientation and dominant and prestigious status-seeking behaviors in a sample of 95 young Chilean men. We did not find evidence that the administration of exogenous testosterone increased short-term or decreased long-term mating orientation as expected. Moreover, exogenous testosterone did not affect either aggressive or cooperative behavior failing to support the social status hypothesis. We also did not find any relationship between short or long-term mating orientation with status-seeking behaviors. Finally, we found support for the effect of social environment on sociosexual attitudes but not over status-seeking behaviors. Thus, men reported higher levels of short-term mating orientation in the presence of a woman compared to a man and no differences were found for long-term mating orientation. We argue that sociosexuality may be expressed flexibly, but contextual factors such as the presence of women seem more important than changes in testosterone levels.

Disgust as a basic, sexual, and moral emotion.

Disgust is a basic emotion that increases the organism's survival success by preventing the transfer of pathogens. In this regard, it directs cognitive processes and motivates avoidance behaviors that prevent pathogens from entering the body. Moreover, disgust has many specific characteristics that distinguish it from other basic emotions. Firstly, unlike other basic emotions, it contaminates neutral objects around it and causes difficult-to-change learning. Another specific characteristic of disgust is that it depends on ideational processes. Objects, situations, and behaviors that do not contain pathogens can also cause disgust. In this regard, disgust appears not only as a basic emotion but also as different adaptations in different fields. In this context, two distinct adaptations of disgust stand out: sexual and moral disgust. These two adaptations of disgust benefit from disgust-related behaviors and motivations in different ways. Sexual disgust works as a gene protection mechanism, while moral disgust helps maintain social rules. The specific characteristics of disgust and its effects on cognitive processes such as attention and memory interact. In conclusion, the multifaceted structure of disgust shows that it needs to be studied more in the subfields of psychology. (Strohminger, Philos Compass 9:478-493, 2014) defines disgust as a psychological nebula that needs to be discovered. However, it is observed that disgust has not been adequately addressed. This review aims to comprehensively explore unique characteristics and diverse aspects of disgust, shedding light on its significance from various perspectives. This study underscores the broader understanding of disgust and its pivotal role in psychological research.

Orgasm Consistency in Mixed-Gender Couples: Actor, Partner, and Discrepancy Effects from Dyadic Response Surface Analysis.

The potential link between orgasm consistency (i.e., the percentage of time an individual experiences orgasm during sexual interactions with a partner) and sexual satisfaction in mixed-gender sexual relationships remains underexamined in the literature. We combined two dyadic samples (N = 725 couples) and utilized Dyadic Response Surface Analysis (DRSA) to examine how both partners' orgasm consistency and their discrepancy of orgasm consistency predict both partners' sexual satisfaction. We found that partners' discrepancy in orgasm consistency was not uniquely connected to higher sexual satisfaction for either women or men; rather, the overall consistency of orgasm was connected to better sexual satisfaction for both partners. In addition, there was some evidence tentatively suggesting that men were more likely than women to report lower sexual satisfaction if his partner was orgasming more consistently than he was, as opposed to her reporting lower sexual satisfaction from him orgasming more consistently than she was; though this appears to be a rare scenario as only 5.9% of couples had women who orgasmed more consistently than men. This study may assist educators and clinicians as they help couples consider the sexual scripts surrounding orgasm consistency, and how they can attend to each others' desires in a way that maximizes sexual satisfaction for both partners.

Exploring Women's State-Level Anxiety in Response to Virtual Reality Erotica.

Virtual Reality (VR)-based treatments for anxiety disorders are efficacious but there is a lack of research examining anxious responses to VR erotica, which could innovate treatments for sexual difficulties. We examined erotica features that elicited anxiety and sexual presence in women. Thirty-eight women viewed erotic videos from different modalities (2D, VR) and points of view (1st, 3rd person) and completed anxiety and sexual presence measures before and after each video. Women experienced greater anxiety for VR than 2D films and reported the most anxiety for VR 1st person films. Sexual presence was affected by modality and point of view.

Prevalencia y caracterización de las disfunciones sexuales en mujeres en transición a la menopausia / Prevalence and characterization of sexual dysfunctions in women in transition to menopause

Objetivo: Caracterizar las disfunciones sexuales y estimar la prevalencia en un grupo de mujeres en transición a la menopausia, así como evaluar la frecuencia de la sintomatología climatérica. Método: Estudio de corte transversal, entre 2017 y 2020, que incluyó 411 mujeres en transición a la menopausia, residentes en el Quindío, con pareja estable y actividad sexual en las últimas 6 semanas. Se utilizó como instrumento el FSFI-6 (6-Item Female Sexual Function Index). Resultados: La edad promedio fue de 46,53 ± 2,87 años. La prevalencia de disfunciones sexuales fue del 38,92%, caracterizadas por dificultades con el deseo sexual (38,92%), seguido de dolor/dispareunia (35,52%). El promedio general en la puntuación del FSFI-6, en la totalidad de la población participante, fue de 22,29 ± 0,84 puntos; en la población afectada (< 19 puntos) fue de 15,78 ± 3,94. En los dominios, la puntuación más baja estuvo en el deseo (3,14 ± 0,56). La mediana de disfunciones sexuales por mujer fue de tres (23,84%). Conclusiones: más de un tercio de las mujeres del Quindío en transición a la menopausia presentan disfunciones sexuales; el trastorno más común fue el bajo deseo. Se deben hacer esfuerzos para aumentar la conciencia en los asuntos de salud sexual.

Objective: To characterize sexual dysfunctions and estimate the prevalence in a group of women in transition to menopause, as well as to evaluate the frequency of climacteric symptoms. Method: Cross-sectional study, between 2017 and 2020, included 411 women in transition to menopause, residents of Quindío, with a stable partner and sexual activity in the last 6 weeks. The FSFI-6 (6-Item Female Sexual Function Index) was used as an instrument. Results: The mean age was 46.53 ± 2.87 years. The prevalence of sexual dysfunctions was 38.92%, characterized by difficulties with sexual desire (38.92%), followed by pain/dyspareunia (35.52%). The general average, in the FSFI-6 score, in the entire participating population, was 22.29 ± 0.84 points; while in the affected population (< 19 points), it was 15.78 ± 3.94. In the domains, the lowest score was in desire (3.14 ± 0.56). The median number of sexual dysfunctions per woman was three (present in 23.84%). Conclusions: This study showed that more than one third of the women in Quindío, in transition to menopause, had sexual dysfunctions; the most common type of disorder was low desire. Efforts should be made to increase awareness about sexual health issues.

Hypothalamic control of innate social behaviors.

Sexual, parental, and aggressive behaviors are central to the reproductive success of individuals and species survival and thus are supported by hardwired neural circuits. The reproductive behavior control column (RBCC), which comprises the medial preoptic nucleus (MPN), the ventrolateral part of the ventromedial hypothalamus (VMHvl), and the ventral premammillary nucleus (PMv), is essential for all social behaviors. The RBCC integrates diverse hormonal and metabolic cues and adjusts an animal's physical activity, hence the chance of social encounters. The RBCC further engages the mesolimbic dopamine system to maintain social interest and reinforces cues and actions that are time-locked with social behaviors. We propose that the RBCC and brainstem form a dual-control system for generating moment-to-moment social actions. This Review summarizes recent progress regarding the identities of RBCC cells and their pathways that drive different aspects of social behaviors.

Partner responses to low desire among couples coping with male hypoactive sexual desire disorder and associations with sexual well-being.

BACKGROUND: Hypoactive sexual desire disorder (HSDD) is characterized by persistently low desire and associated distress. Low desire is one of the most common sexual complaints among men and is associated with poor well-being. Interpersonal factors are key to understanding low desire, yet there are few dyadic studies of HSDD in men. Previous work on genito-pelvic pain and low desire in women has established that greater facilitative (eg, affectionate) partner responses are associated with greater sexual satisfaction and function and that more negative (eg, critical) or solicitous (eg, sympathetic, avoidant) partner responses are associated with lower sexual satisfaction and function. Examining how partner responses are associated with adjustment to HSDD may shed light on the interpersonal dynamics of this understudied sexual dysfunction. AIM: In a cross-sectional study, we examined whether partner responses to low desire in men were associated with sexual desire, sexual satisfaction, and sexual distress for both members of the couple. METHODS: Men with HSDD and their partners (N = 67 couples) completed measures of facilitative, negative, and avoidant partner responses to men's low sexual desire-as perceived by the man with HSDD and self-reported by their partner-and sexual desire, sexual satisfaction, and sexual distress. Data were analyzed using multilevel modeling guided by the actor-partner interdependence model. OUTCOMES: Outcomes included the partner-focused subscale of the Sexual Desire Inventory-2, Global Measure of Sexual Satisfaction, and Sexual Distress Scale-Revised. RESULTS: When men with HSDD perceived more facilitative partner responses to their low desire, they and their partners reported greater sexual satisfaction. When men with HSDD perceived and their partners self-reported more negative partner responses, they each reported lower sexual satisfaction. In addition, when men with HSDD perceived more avoidant partner responses, their partners reported greater sexual distress. Partner responses were not associated with sexual desire for either member of the couple. CLINICAL IMPLICATIONS: Findings support the importance of the interpersonal context for HSDD in men and suggest potential future targets of treatment when working with affected couples. STRENGTHS AND LIMITATIONS: This study is one of the only dyadic studies of HSDD in men, as assessed via clinical interview or self-report symptoms reviewed by the clinical team. Despite our best efforts to recruit this sample over 6 years, the small size limited power to detect all predicted effects. CONCLUSION: More facilitative and fewer negative or avoidant partner responses to low desire are associated with greater sexual well-being in couples coping with HSDD.
