RESUMO
BACKGROUND: There are currently no Food and Drug Administration-approved treatments for female sexual arousal disorder (FSAD), which is physiologically analogous to male erectile dysfunction. AIMS: The study sought to test the systemic and local genital safety of topical sildenafil cream, 3.6% (sildenafil cream) among healthy premenopausal women with FSAD and their sexual partners over a 12-week treatment period. METHODS: This was a phase 2b, exploratory, randomized, placebo-controlled, double-blind study of sildenafil cream among healthy premenopausal women with FSAD. Safety was assessed by the frequency and incidence of treatment-emergent adverse events (TEAEs) among participants and their sexual partners. Participants recorded the incidence of TEAEs in a daily eDiary (electronic diary). Sexual partners were contacted within 72 hours of each sexual event in which investigational product was used. All participants used placebo cream for 1 month, during a single-blind run-in period, and then if eligible, were randomized 1:1 to sildenafil cream or placebo cream. Participants used their assigned investigational product over a 12-week double-blind dosing period. They attended monthly follow-up visits, in which their eDiary TEAE data were reviewed by the study staff and graded for severity and relationship to study product. OUTCOMES: The frequency and incidence of TEAEs among participants and their sexual partners. RESULTS: During the 12-week double-blind dosing period, there were 78 TEAEs reported by 29 of 99 sildenafil-assigned participants and 65 TEAEs reported by 28 of 94 placebo-assigned participants (P = .76). All TEAEs were mild or moderate in severity. The most common treatment-related TEAE among active and placebo-assigned participants was application site discomfort. There were no differences in the number of treatment-related TEAEs among sildenafil cream vs placebo cream users (P > .99). Four sildenafil cream participants and 3 placebo cream participants discontinued the study due to TEAEs involving application site discomfort (P > .99). There were 9 TEAEs reported by 7 of 91 sexual partners exposed to sildenafil cream vs 4 TEAEs reported by 4 of 84 sexual partners exposed to placebo cream (P = .54). CLINICAL IMPLICATIONS: These data support further clinical development of topical sildenafil cream for the treatment of FSAD. STRENGTHS AND LIMITATIONS: Safety was assessed among participants and their sexual partners after 1357 and 1160 sexual experiences in which sildenafil cream or placebo cream were used, respectively. The phase 2b study was powered for the primary objectives of efficacy, rather than safety. CONCLUSION: These data demonstrate that topically applied sildenafil cream was safe and well tolerated by exposed users and their sexual partners.

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.

BACKGROUND: Efficacy assessments in clinical trials of treatments for female sexual arousal disorder (FSAD) and other female sexual dysfunction (FSD) diagnoses rely on various patient-reported outcomes (PROs). AIMS: We sought to compare 1-month recall PRO measures among participants enrolled in a clinical trial who provided these data without (test population) vs with (control population) use of an at-home, 24-hour recall electronic diary (eDiary), capturing similar data. METHODS: Preplanned subset analysis as performed during a phase 2b, exploratory, randomized, placebo-controlled, double-blind study of sildenafil cream, 3.6% (sildenafil cream) among healthy premenopausal women with FSAD. Preliminary product efficacy was assessed via 1-month recall and 24-hour recall questionnaires. A subset of the participants, the Evaluation of Recall Subset [ERS] provided PROs via the 1-month recall instruments but did not provide data via the 24-hour recall eDiary. OUTCOMES: Responses to the 1-month recall instruments were compared among ERS (test) vs non-ERS (control) participants. Among the non-ERS population, correlations between 1-month and 24-hour recall endpoints were calculated. RESULTS: There were no significant differences in the study co-primary 1-month recall efficacy endpoints, the Arousal Sensation (AS) domain of the 28-item Sexual Function Questionnaire (SFQ28) and the Female Sexual Distress Scale - Desire, Arousal, Orgasm question 14, among ERS vs non-ERS participants during the initial 1-month no-drug run-in period or the 1-month single-blind placebo run-in period (P values > .47). Scores on these 1-month recall PROs continued to be similar after randomization for sildenafil cream (P values > .30) and placebo cream (P values > .20) assigned ERS and non-ERS participants during the 3-month double-blind dosing period. There were strong correlations between the SFQ28 AS and eDiary AS scores during the no-drug run-in (R = 0.79, P < .01) and the single-blind run-in (R = 0.73 P < .001). During the double-blind dosing period, the SFQ28 AS score continued to be highly correlated with the eDiary AS score among sildenafil cream users (R = 0.83; P < .001) and placebo cream users (R = 0.8; 2 P < .001). CLINICAL IMPLICATIONS: There was no evidence that 1-month recall PRO instruments introduce recall bias; assessing arousal sensations with 24-hour vs 1-month PRO instruments is similar and either method could be used to assess efficacy depending on study objectives. STRENGTHS AND LIMITATIONS: This preplanned subset analysis compared efficacy of PROs based on recall duration. While the subset was preplanned, the study was powered to detect significant differences in the primary efficacy objectives, not among this subset analyses. CONCLUSION: These data will be used in planning future efficacy assessments of sildenafil cream for FSAD. CLINICAL TRIAL REGISTRATION: This clinical trial was registered with ClinicalTrials.gov, NCT04948151.

BACKGROUND: Sexual interest/arousal disorder (SIAD) is one of the most common sexual problems for women. In clinical research, there are often misalignments between the research priorities of patients and researchers, which can negatively impact care, and gender-diverse individuals are often excluded from research. Inclusion of patient perspectives when establishing research priorities may help to reduce these gaps; however, the research priorities of couples coping with SIAD remain unclear. AIM: Identify the research priorities of women and gender-diverse individuals with SIAD and their partners. METHODS: In an online survey, couples coping with SIAD provided consent and responded to an open-ended question asking them to list the top 3 things they think are important for researchers to focus on related to couples coping with low sexual desire. A team-based content analysis was conducted to identify themes and their frequency of endorsement. OUTCOMES: An author-developed open-ended question. RESULTS: Analysis of 1279 responses (n = 667 from women and gender-diverse individuals with SIAD, n = 612 from partners) resulted in our identification of 6 main themes: general causes, general treatment and coping, biophysiological, relationship, psychological, and environmental/contextual. Additionally, we identified 4 sub-themes within each of the latter 4 main themes: general, cause, treatment, and impact. For women and gender-diverse individuals with SIAD, their partners, and specifically gender-diverse participants, the 3 most endorsed themes were psychological general factors (24.3%, 21.2%, 24.3%; eg, stress and the link between SIAD and anxiety), relationship general factors (15.7%, 13.2%, 18.6%; eg, relationship length and communication on sexual desire), and biophysiological general factors (12.3%, 12.4%, 14.3%; eg, research on medications and hormones). CLINICAL IMPLICATIONS: Clinical researchers should consider the research priorities of couples coping with SIAD to ensure their work aligns with the needs of the affected population. STRENGTHS AND LIMITATIONS: This study is the first to identify the research priorities of both women and gender-diverse individuals with SIAD and their partners. Most participants identified as heterosexual, North American, and of middle to high socioeconomic status; results may not generalize. Responses were sometimes brief and/or vague; interpretation of these responses was therefore limited and may have required more contextual information. CONCLUSION: Findings suggest that women and gender-diverse individuals with SIAD, their partners, and gender-diverse participants have similar research priorities that are consistent with a biopsychosocial approach to research. Heterogeneity of responses across themes supports a multidisciplinary, patient-oriented approach to SIAD research.
RESUMO
Problematic sexual arousal (PSA) is an umbrella term to describe a range of clinical presentations related to excessive sexual thinking (e.g., sexual preoccupation) and sexual behavior (e.g., hypersexuality). Although such concepts are known to affect sexual recidivism among individuals convicted of sexual offences, PSA is not routinely or directly targeted in offending behavior programs in England and Wales. However, in recent years, there have been moves to incorporate pharmacological interventions for addressing this among people with sexual offence histories. Although some work to understand the experiences of those taking SSRI medication for this purpose has emerged, little is known about the experiences of service users taking anti-androgen medication. In this study, we interviewed all individuals in prison taking anti-androgens for the treatment of problematic sexual arousal following convictions for sexual offences in England at the time of data collection (N = 10). Using a phenomenologically oriented thematic analysis, we established themes pertaining to "Differing needs: Motivations for treatment," "Medication as a risk management strategy," and how the medication helped the men in their pursuit of "Discovering a 'new me'." This work contributes important knowledge to inform the development of ethical and effective prescribing of anti-androgen medication with this population and offer recommendations for both future research and the development of clinical practice.

Assessing another person's intention to flirt and, relatedly, their sexual interest is based on the interpretation and weighting of global (e.g., clothing style) and specific (e.g., facial expression) cues. Since cue incongruency increases the risk of erroneous judgments and thus can entail undesirable outcomes for both parties involved, detection of an individual propensity for overly relying on global (sexual) rather than specific (affective) cues is of social and clinical-forensic importance. Using a purpose-designed and pre-validated stimulus set, we developed a mouse-tracking task as an indirect behavioral measure for males' overreliance on global cues (OGC) in the context of sexual flirting. In a convenience sample of heterosexual cisgender men (N = 79), experimentally induced sexual arousal was shown to increase the probability of OGC as a function of task difficulty (i.e., congruent or incongruent combinations of global and specific cues displayed by a potential female flirting partner). While error rate and reaction time proved to be indicators of OGC, the spatial measures maximum deviation and area under the curve provided less consistent results. In addition, error rate suggested sex drive and sexual objectification to act as moderators of the relationship between sexual arousal and OGC. Exploratory analysis further revealed a theoretically meaningful pattern of correlations between mouse-tracking measures and self-report measures of problematic (e.g., disinhibited, exploitative) sexuality. Implications of the results are discussed and a framework for differentiating potential causes of OGC (i.e., misperception, lack of self-control, and egocentric hedonism) is proposed.

Sexual arousal in male and female victims during nonconsensual sex is an understudied phenomenon with many potential psychological, clinical, and legal implications for survivors. The aim of this scoping review was to assess the literature to determine whether we could estimate the frequency and circumstances of physiological sexual arousal (e.g., erection, lubrication, ejaculation, orgasm) among victims during nonconsensual sex. Six reference database and hand searches led to the screening of 13,894 articles and other reports. Eight articles and one book published between 1977 and 2019 included relevant data from 136 male survivors and 250 female survivors. Results confirmed that physiological sexual arousal (only genital responses were mentioned) can occur in both male and female victims during nonconsensual sex. The frequency of these responses could not be determined because of the widely different methodologies used. In addition, it was not possible to determine the circumstances in which victim sexual arousal was more likely to occur although some were inferred. The results of the scoping review highlight that physiological sexual arousal during nonconsensual sex does occur for victims but has not been studied systematically. There is a clear need to properly assess the type, circumstances, consequences, and frequency of sexual arousal during nonconsensual sex in large and diverse populations of male and female survivors.

Little is known about the role of subjective sexual arousal within romantic relationships. The current paper addresses this limitation using a prospective study design that investigates the direct associations between subjective sexual arousal induced by a romantic partner (partner arousal) and arousal induced by pornography (porn arousal) on changes in relational outcomes. A total of 309 participants who were in a current romantic relationship completed measures of partner and porn arousal as well as relational outcomes (i.e., sexual satisfaction and relationship quality and stability) at baseline (T1) and completed a second assessment of relational outcomes 2 months later (T2). Partner arousal was found to have no significant associations with changes in relational outcomes; however, porn arousal was associated with significant declines in sexual satisfaction and relationship quality and stability over a 2-month period. This paper is the first to examine how feeling sexually aroused by porn may impact relational outcomes for those in romantic relationships.

Although women and men rate their subjective arousal similarly in response to "female-centric" erotic videos, women rate their subjective arousal lower than men in response to "male-centric" videos, which often end with the male's ejaculation. This study asked whether ratings of subjective sexual arousal and desire using the Sexual Arousal and Desire Inventory (SADI) would be altered if this ending was present or absent, and whether including or excluding the accompanying soundtrack would influence the magnitude and direction of the responses. A total of 119 cis-gendered heterosexual undergraduates (59 women and 60 men) viewed an 11-min sexually explicit heterosexual video that ended with a 15-s ejaculation scene. Two versions of the video were created, one with the ejaculatory ending (E+) and one without (E-). Participants were assigned randomly to view one of the two versions with (S+) or without (S-) the accompanying soundtrack, after which they completed the state version of the SADI. Women and men found both sequences without sound less arousing on the Evaluative, Motivational, and Physiological subscales of the SADI relative to the S+ sequences. However, on the Negative/Aversive subscale, women found the E + S- sequence more negative than did men, whereas this difference was not found with sound. Thus, women and men were sensitive to the auditory content of sexually explicit videos, and scenes of sexual intercourse ending with explicit ejaculation increased the Evaluative and Motivational properties of subjective sexual arousal and desire. However, this occurred in women only when the auditory cues signaled a clear and gratifying sexual interaction.

Self-reported sexual orientation of transgender individuals occasionally changes over transition. Using functional magnetic resonance imaging, we tested the hypothesis that neural and behavioral patterns of sexual arousal in transgender individuals would shift from the assigned to the experienced gender (e.g., trans women's responses becoming more dissimilar to those of cis men and more similar to those of cis women). To this aim, trans women (N = 12) and trans men (N = 20) as well as cisgender women (N = 24) and cisgender men (N = 14) rated visual stimuli showing male-female, female-female or male-male intercourse for sexual arousal before and after four months of gender-affirming hormone therapy. A Bayesian framework allowed us to incorporate previous behavioral findings. The hypothesized changes could indeed be observed in the behavioral responses with the strongest results for trans men and female-female scenes. Activation of the ventral striatum supported our hypothesis only for female-female scenes in trans women. The respective application or depletion of androgens in trans men and trans women might partly explain this observation. The prominent role of female-female stimuli might be based on the differential responses they elicit in cis women and men or, in theory, the controversial concept of autogynephilia. We show that correlates of sexual arousal in transgender individuals might change in the direction of the experienced gender. Future investigations should elucidate the mechanistic role of sex hormones and the cause of the differential neural and behavioral findings.The study was registered at ClinicalTrials.gov (NCT02715232), March 22, 2016.

The sense of agency varies as a function of arousal in negative emotional contexts. As yet, it is unknown whether the same is true for positive affect, and how inter-individual characteristics might predict these effects. Temporal binding, an implicit measure of the sense of agency, was measured in 59 participants before and after watching either an emotionally neutral film clip or a positive film clip with high or low arousal. Analyses included participants' individual differences in subjective affective ratings, physiological arousal (pupillometry, skin conductance, heart rate), striatal dopamine levels via eye blink rates, and psychopathy. Linear mixed models showed that sexual arousal decreased temporal binding whereas calm pleasure had no facilitation effect on binding. Striatal dopamine levels were positively linked whereas subjective and physiological arousal may be negatively associated with binding towards actions. Psychopathic traits reduced the effect of high arousal on binding towards actions. These results provide evidence that individual differences influence the extent to which the temporal binding is affected by high arousing states with positive valence.

As state-of-art technology can create artificial images that are indistinguishable from real ones, it is urgent to understand whether believing that a picture is real or not has some import over affective phenomena such as sexual arousal. Thus, in two pre-registered online studies, we tested whether 60 images depicting models in underwear elicited higher self-reported sexual arousal when believed to be (N = 57) or presented as (N = 108) real photographs as opposed to artificially generated. In both cases, Realness correlated with significantly higher scores on self-reported sexual arousal. Consistently with the literature on downregulation of emotional response to fictional works, our result indicates that sexual images that are perceived to be fake are less arousing than those believed to portray real people.

Survivors of adult sexual assault and child sexual abuse - together encompassing sexual violence (SV) - experience a number of adverse consequences. High rates of self-blame can lead to increased symptomatology and treatment resistance. There has been a paucity of studies of men who have experienced SV, particularly about self-blame. For this study, 179 cisgender male survivors of SV completed an online survey to explore the relationships among 10 variables, including trauma-related self-blame, rape myth acceptance, tonic immobility, disclosure experiences, sexual arousal, and substance use. Multiple regression analyses and t-tests were used to test the study hypotheses. Results indicate that 93% of the sample reported some level of self-blame. However, only rape myth acceptance was strongly associated with self-blame. Additionally, participants who used substances within 12 hours prior to their SV had higher rates of self-blame, as did participants who had not previously disclosed their abuse. Exploratory analyses also found a significant difference in self-blame between those who experienced SV in childhood and adulthood versus those who only experienced SV in either childhood or adulthood. The findings of this research highlight the high rates of self-blame and how imperative it is to provide psychoeducation about the variables discussed in this study and to normalize these experiences, especially for less well-known phenomena such as physiological sexual arousal and TI.
RESUMO
BACKGROUND: Persistent genital arousal disorder (PGAD) is a condition characterized by unwanted and potentially painful genital sensations or spontaneous orgasms without stimulation. We present a case of a 55-year-old woman with refractory genital arousal disorder that was treated with serial pudendal nerve blocks. CASE: RW is a 55-year-old woman with chronic pelvic pain, pudendal neuralgia, MDD, SI, GAD, CRPS, and persistent genital arousal disorder for 11 years. Her PGAD was refractory to conservative management, physical therapy, and bilateral clitoral artery embolization. We performed bilateral pudendal nerve blocks with Kenalog and Bupivacaine, which provided almost complete relief for 2-3 months. We performed a bilateral pudendal nerve radiofrequency ablation; however, there was minimal benefit. RW continues to have significant relief with serial pudendal nerve blocks. SUMMARY AND CONCLUSION: Persistent genital arousal disorder is often refractory to medication and physical therapy requiring significant intervention such as entrapment surgery or artery embolization. Our case demonstrates pudendal nerve blocks as a potential treatment modality with minimal side effects.

Cohen syndrome (CS) is a rare multisystem autosomal recessive disorder associated with mutations in VPS13B (vacuolar protein sorting homolog 13B). The NAPB-related neurodevelopmental disorder is characterized mainly by early-onset epileptic encephalopathy (EOEE) and is associated with mutations in NAPB that encodes for SNAP-beta (soluble NSF attachment protein beta). Here we describe male triplets, clinically presenting with the phenotype of subtle but distinctive facial features, intellectual disability, increased body weight, neonatal EOEE, and prominently variable abnormal behaviors of autism and sexual arousal. The EEG showed multifocal epilepsy, while the brain MRI showed no abnormalities. Diagnostic exome sequencing (ES), the applied next-generation sequencing approach, revealed the interesting finding of two novel homozygous variants in two genes: VPS13B missense variant (c.8516G > A) and NAPB splice-site loss (c.354 + 2 T > G). Sanger sequencing verified the segregation of the two recessive gene variants with the phenotype in family members. The prediction algorithms support the pathogenicity of these variants. Homozygosity mapping of ES data of this consanguineous family revealed multiple chromosomal regions of homozygosity stretches with the residing of VPS13B (chr8: 100830758G > A) and NAPB (Chr20: 23,375,774 A > C) variants within the largest homozygous blocks further supporting the disease-genes causal role. Interestingly, the functions of the two proteins; VPS13B, a transmembrane protein involved in intracellular protein transport, and SNAP-beta involved in neurotransmitters release at the neuronal synaptic complexes, have been associated with Golgi-mediated vesicular trafficking. Our ES findings provide new insights into the pathologic mechanism underlying the expansion of the neurodevelopmental spectrum in CS and further highlight the importance of Golgi and Golgi-membrane-related proteins in the development of neurodevelopmental syndromes associated with early-onset non-channelopathy epilepsy. To our knowledge, this is the first report documenting multifocal EOEE in CS patients with the association of a pathogenic NAPB variant.

Sex differences in brain activity evoked by sexual stimuli remain elusive despite robust evidence for stronger enjoyment of and interest toward sexual stimuli in men than in women. To test whether visual sexual stimuli evoke different brain activity patterns in men and women, we measured hemodynamic brain activity induced by visual sexual stimuli in two experiments with 91 subjects (46 males). In one experiment, the subjects viewed sexual and nonsexual film clips, and dynamic annotations for nudity in the clips were used to predict hemodynamic activity. In the second experiment, the subjects viewed sexual and nonsexual pictures in an event-related design. Men showed stronger activation than women in the visual and prefrontal cortices and dorsal attention network in both experiments. Furthermore, using multivariate pattern classification we could accurately predict the sex of the subject on the basis of the brain activity elicited by the sexual stimuli. The classification generalized across the experiments indicating that the sex differences were task-independent. Eye tracking data obtained from an independent sample of subjects (N = 110) showed that men looked longer than women at the chest area of the nude female actors in the film clips. These results indicate that visual sexual stimuli evoke discernible brain activity patterns in men and women which may reflect stronger attentional engagement with sexual stimuli in men.

BACKGROUND: Although oral contraceptive pills (OCPs) have been associated with decrements in self-reported genital arousal and vaginal lubrication, 1,2 little is known about how these outcomes vary across types of OCPs. AIM: The present study examined differences in physiological lubrication and vaginal blood flow, as well as rates of self-reported vulvovaginal atrophy and female sexual arousal disorder, among women using OCPs with varying androgenic properties. METHODS: Participants in this study were 130 women: 59 naturally cycling control women, 50 women taking androgenic OCPs, and 21 women taking antiandrogenic OCPs. Participants watched sexual films while their sexual arousal responses were measured, completed questionnaires, and participated in a clinical interview. OUTCOMES: Vaginal blood flow, vaginal lubrication, self-reported vulvovaginal atrophy, and female sexual arousal disorder were assessed. RESULTS: Results indicated deficits in vaginal pulse amplitude and lubrication for women taking either form of OCP, with marked inhibitory effects found in women taking antiandrogenic OCPs. Rates of self-reported vulvovaginal atrophy and female sexual arousal disorder were also significantly greater in the antiandrogenic group compared with the control group. CLINICAL IMPLICATIONS: It is recommended that prescribing clinicians consult patients on such physiological effects of OCPs. STRENGTHS AND LIMITATIONS: To our knowledge, this was the first study to compare multiple measures of physiological sexual arousal across groups of women taking OCPs with varying hormonal profiles. Because all OCPs included in this study contained low doses of ethinylestradiol, we were able to identify the specific effects of the androgenic properties on women's sexual arousal responses. However, the self-administered lubrication test strip was subject to user error. Additionally, the generalizability of findings is limited by the largely heterosexual and college-aged sample. CONCLUSION: Compared with naturally cycling women, women taking OCPs that contain antiandrogenic progestins experienced decreased vaginal blood flow and lubrication as well as higher rates of self-reported vaginal bleeding and female sexual arousal disorder.

BACKGROUND: Although sexual arousal is commonly experienced in the daily context of relationships, most of what we know about sexual arousal comes from studies on individuals, often conducted in a laboratory context. AIM: To explore to what extent similarity in levels of sexual arousal during nongenital physical intimacy (ie, cuddling and kissing) was associated with each partner's affect as well as sexual and relationship satisfaction. METHODS: Ninety-four cohabitating couples (mean ± SD age, 26.30 ± 7.60; 88 mixed gender, 6 same gender) completed 6 ecological momentary assessments a day for 10 consecutive days. We used response surface analysis to examine the associations among the degree and direction of similarity in partners' sexual arousal and affective, sexual, and relational outcome variables. OUTCOMES: Sexual satisfaction, relationship satisfaction, and positive and negative affect. RESULTS: Sexual arousal levels covaried only when partners engaged in physically intimate behaviors, unlike affective responses, which covaried within couples more globally over time. Within-couple similarity at high levels of sexual arousal was positively associated with women's sexual satisfaction but unrelated to men and women's relationship satisfaction and affect. Individual- and couple-level sexual arousal was positively associated with men's sexual satisfaction and women's sexual and relationship satisfaction. Couple-level sexual arousal was relevant to men's affect such that positive affect was higher when sexual arousal levels within the couple were high. Our analyses also revealed a discrepancy effect in that women's positive affect was higher when their own sexual arousal levels were higher than those of their partners. CLINICAL IMPLICATIONS: These findings suggest that as long as sexual arousal levels within a couple are sufficiently high, sexual arousal similarity and discrepancy can be beneficial to one's well-being, supporting the relevance of therapeutical techniques aimed at increasing arousal levels to promote a better affective and relational climate for couples. STRENGTHS AND LIMITATIONS: This study is the first to test the daily associations among sexual arousal similarity and its correlates in a sample of cohabitating couples, providing a more comprehensive view of the interpersonal dynamics through which sexual arousal may influence individual, relational, and sexual well-being. Given our sample's relatively young age, as well as high sexual and relationship satisfaction, the results may not generalize to couples experiencing sexual or relational distress. CONCLUSION: Within the context of daily relationships, individual- and couple-level dynamics of sexual arousal were associated with sexual and relationship satisfaction, as well as with affective responses of relationship partners.

BACKGROUND: Approximately 26% of adult women in the United States suffer from female sexual arousal disorder (FSAD), yet little has been done to compare the experience of FSAD in pre- and postmenopausal women, which is critical to enhance the current understanding of FSAD and inform the development and assessment of treatment options for these patient populations. AIM: To explore the experience of condition-associated symptoms and the relative importance of FSAD symptoms, including their severity, bother, and impact, on participants' health-related quality of life (HRQoL) in pre- and postmenopausal women with FSAD. METHODS: In-depth, qualitative, semistructured concept elicitation interviews were conducted with premenopausal (n = 23) and postmenopausal (n = 13) women who were clinically diagnosed with FSAD by a trained sexual medicine clinician. All interviews were audio recorded and transcribed verbatim by a professional transcription company. Thematic analysis was performed with the assistance of NVivo qualitative analysis software. OUTCOMES: Outcomes included qualitative interview data about FSAD symptoms and HRQoL, as well as a comparison between pre- and postmenopausal populations. RESULTS: The most frequently reported symptom in both cohorts was "inability or difficulty with orgasm" (premenopausal, n = 21; postmenopausal, n = 13). The symptom that premenopausal women most desired to have treated was lubrication, and for postmenopausal women, it was a lack of lubrication or wetness and loss of feeling/sensation. In total, 21 of 23 premenopausal women and all 13 postmenopausal women reported a lack of feeling or sensation in the genitals. The most frequently reported HRQoL impact in both groups was decreased confidence. CLINICAL IMPLICATIONS: Results from this study suggest that the manifestation and experience of FSAD are similar in pre- and postmenopausal women and that the unmet need for an FSAD treatment in the postmenopausal population is just as great as that of the premenopausal population. STRENGTHS AND LIMITATIONS: This study involved in-depth qualitative interviews with a relatively small group of women (N = 36) recruited from only 5 study sites across the United States. CONCLUSION: The analysis of qualitative data from the concept elicitation interviews revealed a substantial physical and emotional burden of FSAD, underscoring the need for Food and Drug Administration-approved treatment options for pre- and postmenopausal women with FSAD.

Many reviews on sexual arousal in humans focus on different brain imaging methods and behavioral observations. Although neurotransmission in the brain is mainly performed through electrochemical signals, there are no systematic reviews of the electrophysiological correlates of sexual arousal. We performed a systematic search on this subject and reviewed 255 studies including various electrophysiological methods. Our results show how neuroelectric signals have been used to investigate genital somatotopy as well as basic genital physiology during sexual arousal and how cortical electric signals have been recorded during orgasm. Moreover, experiments on the interactions of cognition and sexual arousal in healthy subjects and in individuals with abnormal sexual preferences were analyzed as well as case studies on sexual disturbances associated with diseases of the nervous system. In addition, 25 studies focusing on brain potentials during the interaction of cognition and sexual arousal were eligible for meta-analysis. The results showed significant effect sizes for specific brain potentials during sexual stimulation (P3: Cohen's d = 1.82, N = 300, LPP: Cohen's d = 2.30, N = 510) with high heterogeneity between the combined studies. Taken together, our review shows how neuroelectric methods can consistently differentiate sexual arousal from other emotional states.
