Sexual concordance is defined as the association between genital response and self-reported sexual arousal. Though one might predict a strong association between sexual concordance and awareness of other internal physiological sensations (termed interoception), past research on sexually healthy women has not found these different domains to be related. The aim of the present study was to test the association between interoception and sexual concordance in a clinical sample of women with Sexual I ...[more]

Project description:PurposeData on the role of prolactin (PRL) in the physiologic range in the female sexual response are scanty. We aimed at investigating the association between PRL and sexual function as assessed by the Female Sexual Function Index (FSFI). We explored the presence of a cut-off level of PRL able to identify Hypoactive Sexual Desire Disorder (HSDD).Methods277 pre- and post-menopausal women consulting for Female Sexual Dysfunction (FSD) and sexually active were enrolled in an observational, retrospective study. 42 women were used as no-FSD controls. A clinical, biochemical and psychosexual evaluation was performed. The main outcome measures were: FSFI, Female Sexual Distress Scale-Revised, Middlesex Hospital Questionnaire and Sexual excitation/sexual inhibition scale (SIS/SES).ResultsNormo-PRL FSD women (n = 264) showed lower FSFI Desire score than controls (n = 42), and higher than hyper-PRL FSD women (n = 13). These differences emerged both in pre-menopausal and post-menopausal subjects. In the normo-PRL FSD group, those with PRL in the higher quintile reported higher FSFI Desire scores than those with PRL in the lowest quintile. Women with HSDD presented a lower PRL level than those without (p = 0.032). A ROC curve analysis for PRL showed an accuracy of 0.610 ± 0.044 (p = 0.014) in predicting HSDD. With a threshold of < 9.83 μg/L, sensitivity and specificity for HSDD were 63% and 56%, respectively. Subjects with PRL < 9.83 μg/L also reported lower sexual inhibition (p = 0.006) and lower cortisol levels (p = 0.003) than those with PRL > = 9.83 μg/L.ConclusionsHyper-PRL is associated with low desire; however, among normo-PRL FSD women, those with the lowest levels demonstrated a poorer desire than those with the highest levels. PRL < 9.83 μg/L predicted HSDD and a lower sexual inhibitory trait.

Project description:IntroductionCounts of satisfying sexual events (SSEs) per month have been criticized as an end point in treatment trials of women with hypoactive sexual desire disorder (HSDD) but grounding improvement in sexual desire by assessing changes in sexual behavior remains of some importance.MethodsWe conducted a literature review to find validated measurements that are specific sexual behavioral correlates of low sexual desire. We compared expert-proposed criteria for dysfunctional desire, expert-developed sets of scale items, and self-rated scales developed before issuance of, or in accordance with, the Food and Drug Administration's guidance on developing patient-reported outcomes. Behavioral measurements of HSDD were isolated from these sets of criteria or scales.Main outcome measuresWe outline a plan to evaluate such behavioral measurements of HSDD with reference to SSEs.ResultsEleven rating scales, four expert-originated and seven self-rated scales mainly derived from patient input were identified as well validated and relevant to HSDD. Three recent sets of diagnostic criteria for conditions such as HSDD were compared with the scales. Twenty-four different symptoms were found in the scales. Content found relevant to HSDD during development of the rating scales varied highly among measurements, including the self-rated scales developed in conformity with current recommendations for patient-reported outcome measurements. The only item on all sets was desire for sexual activity. Four other items were in approximately at least half the sets: sexual thoughts or fantasies, frequency of sexual activity, receptivity, and initiations. Sexual thoughts or fantasies were in every expert-derived set but in only three of the seven patient-derived sets. Receptivity was in five of the seven expert-derived sets vs two of the seven patient-derived sets. Frequency of sexual activity was in one of the seven expert-derived sets but in five of the patient-derived sets. Initiation was in approximately half the two sets. All other items were on one to three sets each. We identified three sexual behaviors of validated specificity for female HSDD: frequency of sexual activity, receptivity, and initiations. Six or seven items are relevant and informative. The item on frequency of sexual activity in the Changes in Sexual Functioning-Female scale is the only item that covers frequency of dyadic and solitary sexual activity. An item in the Female Sexual Desire Questionnaire (FSDQ) covers the intuitively relevant topic of frequency of sexual activity motivated by the woman's desire. Three FSDQ items on initiations and two items on receptivity reflect expert opinion on the sexual behaviors of most relevance to HSDD, but the FSDQ has not been validated in women with HSDD.ConclusionsSSEs have been discredited as the primary measurement in clinical trials of women with HSDD, but it would be meaningful to include at least one sexual behavioral symptom specific to HSDD as an end point. Expert-recommended sexual behaviors specifically related to HSDD are irregularly represented in self-rating scales whether developed as in the Food and Drug Administration guidance on patient-reported outcomes or not. Six or seven items on sexual behavior in self-rated scales can be recommended for relevance to women with HSDD in clinical trials. Items on female sexual behavior should be tested in comparison with SSEs in women with HSDD for relevance and for treatment sensitivity, and responder and functional and dysfunctional cutoffs should be determined before incorporation into large-scale clinical trials.

Project description:Sexuality is a basic human need, which is expressed in the context of intimate personal relations. However, in studies of women's sexuality, men's attitudes are often overlooked. Health care providers can benefit from the examination of how both women and men perceive women's sexual desire and what are the most acceptable avenues for treatment for women's hypoactive sexual desire disorder (HSDD). This research aimed to explore differences between women and men on the factors affecting women's sexual desire and the appropriate avenues for treatment. Data were collected using an online questionnaire from 233 heterosexual adults who had a dyadic, steady intimate relationship over most of the previous year. A theory-based questionnaire of 28 items was developed to explore the factors associated with women's sexual desire. One quarter (7/28) of the items affecting women's sexual desire were ranked significantly differently between women and men. Among women, interpersonal issues and physical attraction, and among men, physical attraction and daily hassles were the significant predictors of women's sexual desire. Women more than men endorsed psychological help such as a sex therapist or psychologist as a more appropriate treatment for HSDD, while both men and women viewed the internet as a reasonable way to gain treatment information. Both women and men viewed gynecologists as a more acceptable source of treatment than a family doctor. Religious authorities were the least likely source of treatment advice for both women and men. The results support a multi-dimensional model of women's sexual desire and suggest that psychological interventions to treat HSDD may be preferred by women more than men.

Project description:BackgroundThe Elements of Desire Questionnaire (EDQ) is a patient-reported outcome (PRO) measure developed to evaluate sexual desire and was included in two identically designed phase 3 clinical trials (RECONNECT) as an exploratory endpoint. The EDQ was developed based on a literature review, qualitative research with patients with hypoactive sexual desire disorder (HSDD), and input from clinical experts. This instrument is intended to be used to collect efficacy data in clinical trials evaluating potential treatments for HSDD. The objective of this study was to evaluate the measurement properties of both the monthly and daily recall versions of the EDQ during the RECONNECT trials.MethodsParticipants completed the EDQ daily version for 7 consecutive days prior to selected monthly clinic visits. The monthly recall version was completed at each monthly clinic visit. The analysis population consisted of all subjects with Female Sexual Function Index (FSFI) data at baseline and ≥ 1 follow-up visit.ResultsAt baseline, 1144 and 676 subjects completed the monthly and daily recall EDQs, respectively. The EDQ scores had good internal consistency and test-retest reliability. Monthly and daily recall EDQ scores were correlated with FSFI-desire domain scores at baseline and month 3. Scores from the monthly and daily recall versions were also correlated. After 6 months, there was a significantly greater improvement for bremelanotide versus placebo in both the monthly and daily recall versions (both P < 0.0001).ConclusionsThe results demonstrated that EDQ exhibited good reliability, validity, and sensitivity to change. Consistent with other validated PRO measures of sexual desire, the EDQ provides additional insights into sexual desire.Trial registrationNCT02338960 and NCT02333071 (RECONNECT studies).

Project description:BACKGROUNDHypoactive sexual desire disorder (HSDD) is characterized by a persistent deficiency of sexual fantasies and desire for sexual activity, causing marked distress and interpersonal difficulty. It is the most prevalent female sexual health problem globally, affecting approximately 10% of women, but has limited treatment options. Melanocortin 4 receptor (MC4R) agonists have emerged as a promising therapy for women with HSDD, through unknown mechanisms. Studying the pathways involved is crucial for our understanding of normal and abnormal sexual behavior.METHODSUsing psychometric, functional neuroimaging, and hormonal analyses, we conducted a randomized, double-blinded, placebo-controlled, crossover clinical study to assess the effects of MC4R agonism compared with placebo on sexual brain processing in 31 premenopausal heterosexual women with HSDD.RESULTSMC4R agonism significantly increased sexual desire for up to 24 hours after administration compared with placebo. During functional neuroimaging, MC4R agonism enhanced cerebellar and supplementary motor area activity and deactivated the secondary somatosensory cortex, specifically in response to visual erotic stimuli, compared with placebo. In addition, MC4R agonism enhanced functional connectivity between the amygdala and the insula during visual erotic stimuli compared with placebo.CONCLUSIONThese data suggest that MC4R agonism enhanced sexual brain processing by reducing self-consciousness, increasing sexual imagery, and sensitizing women with HSDD to erotic stimuli. These findings provide mechanistic insight into the action of MC4R agonism in sexual behavior and are relevant to the ongoing development of HSDD therapies and MC4R agonist development more widely.TRIAL REGISTRATIONClinicalTrials.gov NCT04179734.FUNDINGThis is an investigator-sponsored study funded by AMAG Pharmaceuticals Inc., the Medical Research Council (MRC) (MR/T006242/1), and the National Institute for Health Research (NIHR) (CS-2018-18-ST2-002 and RP-2014-05-001).

Project description:Abstract Introduction Hypoactive sexual desire disorder (HSDD) is characterized by a persistent deficiency of sexual fantasies and desire for sexual activity, causing marked distress or interpersonal difficulty. It is the most prevalent female sexual health problem worldwide, affecting approximately 1 in 10 women, but has limited treatment options despite its substantial health, social, and economic burden. Melanocortin-4 receptor (MC4R) agonists have emerged as a promising therapy for women with HSDD, although, to date, their mechanism of action is unknown. This study aims to use functional MRI to delineate the reproductive neuroendocrine pathways involved and elucidate how MC4R agonists treat HSDD in women. Methods We conducted a randomized, double-blinded, placebo-controlled, crossover clinical study, using psychometric, functional neuroimaging and hormonal analyses, to assess the effects of MC4R agonism on sexual brain processing in 31 premenopausal women with HSDD. Participants attended on two occasions, receiving either a subcutaneous injection of an MC4R agonist (Bremelanotide 1.75 mg), or placebo, at each study visit, thereby acting as their own controls. Results 31 randomized women were included (mean age 32 years, mean duration of HSDD 41 months). MC4R agonism significantly increased self-reported sexual desire for up to 24-hours post administration, compared to placebo (P=0.007). During functional neuroimaging, MC4R agonism enhanced cerebellar and supplementary motor area activity, as well as deactivating the secondary somatosensory cortex, specifically in response to visual erotic videos, compared to placebo (Z=2.3, P<0.05). In addition, MC4R agonism enhanced functional connectivity between the amygdala-insula and amygdala-thalamus during prolonged visual erotic stimuli, compared to placebo (P=0.025). MC4R agonism resulted in a mean increase in LH of 1.1 iU/L (F [1,58] = 13.38, P=0.0005), and FSH of 0.35 iU/L (F [1,60] = 10.97, P=0.0016) across the 300-minute duration of the study, with no effect observed on circulating estradiol or progesterone levels. Interpretation of results and conclusions:We demonstrate that MC4R agonism deactivates the secondary somatosensory cortex which can reduce the detrimental self-monitoring process often observed in HSDD, thereby increasing sexual desire. Furthermore, cerebellar and supplementary motor area activation by MC4R agonism are associated with increased sexual arousal and sexual motor imagery respectively. Finally, MC4R agonism enhanced functional connectivity between key limbic structures which can be disrupted in HSDD. In summary, these data identify the previously undescribed neural substrates and connections through which MC4R agonism modulates sexual brain processing to increase sexual desire. These findings provide mechanistic insight for the action of MC4R agonism in sexual behaviour and are relevant to ongoing therapeutic development for HSDD and for MC4R agonist development more widely.

Project description:INTRODUCTION:Female sexual dysfunction affects up to 43% of women in the United States and hypoactive sexual desire disorder (HSDD) is the most common type; however, we lack treatment options showing improvement for this condition. AIMS:To investigate whether acupuncture therapy could improve HSDD. METHODS:Premenopausal women with a primary diagnosis of HSDD were included in a single-arm prospective pilot study that was approved by the institutional review board. After providing informed consent, subjects completed validated questionnaires. Participants underwent 25-minute twice-weekly acupuncture sessions for 5 weeks with one certified acupuncturist. Questionnaires were completed again 6 weeks after onset of treatment. MAIN OUTCOME MEASURES:Based on a statistically significant change in the desire domain of the Female Sexual Function Index from 2.0 (at baseline) to 2.4 (after intervention with a specialist) in our population of patients diagnosed with HSDD, a sample of 13 was determined, with 90% power and ? 0.05. RESULTS:Fifteen women were enrolled and 13 completed the study. Mean age was 36.9 ± 11.4 years. Most were white (n = 9, 60%), heterosexual (n = 15, 100%), and non-smokers (n = 14, 93%). Most were sexually active more than four times per month (n = 8, 53%) and none had a history of sexual abuse (n = 15, 100%). Participants received a mean acupuncture needle application of 17 ± 2 at each session. Sexual function improved after intervention, particularly desire (2.1 ± 0.6 to 3.3 ± 1.2, P < .0001), arousal (P < .0001), lubrication (P = .03), and orgasm (P = .005). CONCLUSION:In this cohort of premenopausal women with HSDD, 5 weeks of acupuncture therapy was associated with significant improvements in sexual function, particularly desire. This supports a role for acupuncture as a therapeutic option for women with low desire.

Project description:Problems related to low sexual desire in women are common clinical complaints, and the aetiology is poorly understood. We investigated predictors of change in levels of sexual desire using a novel network approach, which assumes that mental disorders arise from direct interactions between symptoms. Using population-based data from 1,449 Finnish women, we compared between-subject networks of women whose sexual desire decreased, increased, or remained stable over time. Networks were estimated and analyzed at T1 (2006) and replicated at T2 (2013) using R. Domains included were, among others, sexual functions, sexual distress, anxiety, depression, body dissatisfaction, and relationship status. Overall, networks were fairly similar across groups. Sexual arousal, satisfaction, and relationship status were the most central variables, implying that they might play prominent roles in female sexual function; sexual distress mediated between general distress and sexual function; and sexual desire and arousal showed different patterns of relationships, suggesting that they represent unique sexual function aspects. Potential group-differences suggested that sex-related pain and body dissatisfaction might play roles in precipitating decreases of sexual desire. The general network structure and similarities between groups replicated well; however, the potential group-differences did not replicate. Our study sets the stage for future clinical and longitudinal network modelling of female sexual function.

Project description:BackgroundModels 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).AimTo assess the role of SIAD status and relationship satisfaction in the associations between genital arousal and 4 types of responsive desire.MethodsOne 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).OutcomesOutcomes consisted of genital response (z scored by method) and associations between genital response and responsive sexual desire.ResultsThe 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 implicationsPatterns 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 limitationsThis 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.ConclusionWhen 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.
