Hypoactive Sexual Desire Disorder: International Society for the Study of Women's Sexual Health (ISSWSH) Expert Consensus Panel Review

In the Mood: How Sexual Desire Predicts and is Predicted by Romantic Partners' Mood

The association between mood and sexual desire has been the object of significant scientific and public interest. How mood shapes and is shaped by sexual desire is typically studied within one and the same individual, yet sexual desire is often experienced in the context of a romantic relationship. To obtain a more complete picture of the relation between mood and sexual desire, we examined the temporal interplay between mood and sexual desire both within and between partners in a romantic relationship. Using data from an experience sampling study involving both partners of mixed-gender romantic couples (N = 188; Mage = 26.34, SDage = 5.33), we investigated how each partner's mood (in terms of positive and negative affect) predicted their own sexual desire as well as that of their partner and vice versa. Results of both concurrent and temporal analyses confirmed bidirectional associations between mood and sexual desire both within and between partners, such that (1) both a person's own and their partner's positive mood predicted an increase in sexual desire, and a person's own and their partner's negative mood predicted a decrease in sexual desire. In addition, (2) both a person's own and their partner's sexual desire predicted an increase in positive mood, and a person's own and their partner's sexual desire predicted a decrease in negative mood. Only a few gender differences were found. The results underscore how sexual desire can predict and be predicted by both romantic partners' mood, highlighting the need for interactional models of sexual desire.

Hypoactive sexual desire disorder in women: new possibilities to ensure better understanding, diagnosis, and response to treatment

BACKGROUND

Hypoactive Sexual Desire Disorder (HSDD) is a frequent sex-related problem in women; however, a specific tool to characterize HSDD subtypes based on sexual inhibitory and excitatory factors is still lacking.

AIM

(1) To find a cutoff value in Sexual Inhibition Scale (SIS)/Sexual Excitation Scale (SES) scores predicting a diagnosis of HSDD in women consulting for sexual symptoms, (2) to explore the sexual inhibitory and excitatory profiles in women referred to a clinic for female sexual dysfunction by stratifying the sample according to the newfound cutoffs, and (3) to identify biopsychosocial factors significantly associated with the 2 profiles.

METHODS

An overall 133 women consulting for sexual symptoms were retrospectively evaluated for clinical, biochemical, and psychosexologic data collected at the first visit. A subgroup of 55 women treated with transdermal testosterone was retrospectively analyzed at baseline and the 6-month visit.

OUTCOMES

Patients underwent physical and laboratory examinations and completed the SIS/SES, Female Sexual Function Index, Female Sexual Distress Scale-Revised, Emotional Eating Scale, and Middlesex Hospital Questionnaire.

RESULTS

Specific cutoffs for SIS1 (≥32.5; indicating threat of performance failure) and SES (≤46.5) predicted HSDD diagnosis with an accuracy of 66.4% (P = .002) and 68.7% (P < .0001), respectively. Patients with impaired SIS1 scores showed higher distress and psychopathologic symptoms, while those with impaired SES scores demonstrated lower desire and arousal and a negative association with some metabolic and hormonal parameters. SES score also showed a significant predictive value on testosterone treatment efficacy for HSDD.

CLINICAL TRANSLATION

A better characterization of HSDD would enable individualized treatment based on the main underlying etiologies.

STRENGTHS AND LIMITATIONS

Limitations of the study include the small sample size and cross-sectional retrospective design, with the choice of treatment for HSDD limited to transdermal testosterone. Strengths comprise the thorough and multifactorial evaluation of every aspect potentially affecting inhibitory and excitatory components of sexual desire.

CONCLUSION

Validated cutoffs of SIS/SES scores could allow deep characterization of women diagnosed with HSDD, thus ensuring better tailoring of therapy and prediction of the probability of response to specific treatments.

A systematic literature review of natural products for male sexual dysfunction

This study systematically reviewed the scientific literature on natural remedies for male sexual dysfunction (MSD), including conditions like erectile dysfunction, premature ejaculation, and reduced libido. Limited scientific evidence exists regarding the efficacy and safety of these natural products. To ensure an objective assessment, the study used the Scopus database, followed the PRISMA guidelines, and employed a comprehensive search strategy involving relevant vital concepts, controlled vocabularies, and specific inclusion/exclusion criteria. The analysis included 1504 documents from 624 journals, spanning from 1967 to 2023. The literature showed an annual growth rate of 2.46%, with an average document age of 10.2 years and an average of 23.54 citations per document. India had the highest publication count (319), followed by the United States (164). Conceptual Mapping categorized themes into basic, motor, niche, emerging, and declining categories, including nitric oxide, oxidative stress, phytotherapy, herbal medicine, Asparagus racemosus, and dopamine. This mapping provided a holistic understanding of the field, identified research gaps, and guided the development of new interventions or treatment strategies for MSD. Trend topics include molecular coupling, Ashwagandha, phytochemistry, phosphodiesterase-5, and arginase. The study findings will assist healthcare professionals in making informed decisions when recommending or advising patients about the use of these remedies.

Sexual desire and erotic fantasies questionnaire: development and validation of the sexual desire scale (SDEF1)

The evolution in conceptualization of sexual desire has stimulated many attempts to measure it. However measures able to assess multiple expressions of desire in all sexual identities are still lacking. The main aim of the present study was to test the psychometric properties of the Sexual Desire and Erotic Fantasies questionnaire - Part 1 Sexual Desire (SDEF1), developed as a sex-positive measure of different sexual desire expressions. The SDEF1 was assessed in 1773 participants from the Italian general population (1105 women, 645 men, and 23 other genders; ranged between 18-78 years old, mean age 29.31 ± 10.35) on an online survey, together with the Sexual Desire Inventory - 2, the International Index of Erectile Function, the Female Sexual Function Index, and the Marlowe-Crowne Social Desirability Scale-Short Form. Results support a factorial structure of six dimensions, including 28 items and accounting for 58.11% of the total variance: sexual desire, negative feelings to sexual desire, autoerotic desire, regular partner desire, attractive person desire, and responsive desire. The confirmatory factorial analysis showed satisfactory indexes (RMSEA = 0.042 [90% CI = 0.039-0.045]; GFI = 0.97; NFI = .96; and CFI = 0.97). Regression coefficients ranged from 0.39 to 0.94 and were all statistically significant (p < 0.001). The SDEF1 showed good psychometric properties such as internal reliability, construct, and discriminant validity, and to differentiate women and men with and without sexual difficulties. Men reported significantly higher levels of desire than women in all areas except for desire for a regular partner, were no gender difference was detected. Desire for autoerotic activity was the factor accounting for more variance explained among genders (11.7%). The SDEF1 could be a useful measure to assess different areas of sexual desire and its use could be recommended for clinical and research purposes.

Sexual Dysfunction After Menopause: Guidelines for Assessment and Management

Female sexual dysfunction commonly occurs during the menopause transition and post-menopause due to hormonal, physiologic, and psychosocial factors. Sexuality is important to aging women; however, many are reluctant to seek treatment for their sexual concerns. Clinicians should be adept at managing and treating sexual dysfunction in this population. A multi-dimensional treatment approach that addresses modifiable mental, physical, and psychosocial factors is warranted to improve sexual function and quality of life.

Pharmacotherapy of Hypoactive Sexual Desire Disorder in Premenopausal Women

OBJECTIVE

This review aims to provide an overview of pharmacologic management for hypoactive sexual desire disorder (HSDD) in premenopausal women, with a focus on available agents.

DATA SOURCES

Through a literature search on PubMed, Google Scholar, and ClinicalTrials.gov from 1999 to 2024, studies were selected using the following MeSH search terms: hypoactive sexual desire disorder, premenopause, pharmacologic management, flibanserin, bremelanotide, buspirone, bupropion, and testosterone, excluding those involving postmenopausal women or other sexual disorders. Product monographs were also reviewed.

STUDY SELECTION AND DATA EXTRACTION

Relevant English-language studies or those conducted in humans were considered.

DATA SYNTHESIS

Hypoactive sexual desire disorder, characterized by a lack of motivation for sexual activity, predominantly affects women aged 45 years and older. Treatment involves a multimodal approach, including nonpharmacologic interventions such as psychotherapy and lifestyle adjustments, alongside pharmacologic options. Although bupropion and buspirone may be considered off-label treatments, flibanserin and bremelanotide are the sole medications approved by the Food and Drug Administration for generalized acquired HSDD in premenopausal women. However, caution is advised due to their limited efficacy, potential adverse effects, and transparency issues in reporting.

RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE

Hypoactive sexual desire disorder, while not life-threatening, significantly impacts well-being and relationships. Pharmacotherapy, including options like flibanserin and bremelanotide, is essential within a multidisciplinary approach. Validated tools and objective measures inform tailored premenopausal HSDD care plans and aid in striking a balance between potential risks and adverse effects while maximizing meaningful clinical benefits, including for transgender individuals.

CONCLUSIONS

Clinicians must discern important distinctions between flibanserin, bremelanotide, and other agents when managing premenopausal HSDD. Further research with the most suitable clinical endpoints and consideration of patient factors are crucial before widespread adoption of flibanserin and bremelanotide. Pharmacists are encouraged to embrace this opportunity to provide premenopausal HSDD care in ambulatory and community practice settings.

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.

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.

Characteristics of systemic testosterone therapy for female hypoactive sexual desire disorder-a claims database analysis

BACKGROUND

Testosterone therapy (TTh) is recommended for postmenopausal women with hypoactive sexual desire disorder (HSDD); however, there remain insufficient data to support use of TTh in premenopausal women with sexual dysfunction.

AIM

In this study, we used a large national database to evaluate prescribing trends of TTh for women with HSDD.

METHODS

We conducted a cohort analysis of information from electronic health records acquired from the data network TriNetX Diamond. The study cohort consisted of women 18-70 years of age with a diagnosis of HSDD. We analyzed trends of testosterone prescriptions, routes of testosterone administration, and coadministration of testosterone with estrogen.

OUTCOMES

Despite an increase in rates of testosterone prescriptions for HSDD, there remains a high degree of variability in the duration of treatment, route of administration, and coadministration of estrogen with significant underprescription of testosterone.

RESULTS

Our query of the TriNetX database led to the identification of 33 418 women diagnosed with HSDD at a mean age of 44.2 ± 10.8 years, among whom 850 (2.54%) women received a testosterone prescription. The testosterone prescriptions were highly variable with regard to duration and route of administration and coadministration with estrogen. For all patients until 2015, the prevalence of testosterone prescriptions for HSDD showed a positive quadratic relation was observed. Since 2015 a linear increase in prevalence was observed, with the highest rate of increase for patients aged 41-55 years.

CLINICAL IMPLICATIONS

The findings of this study reveal a significant need for further research investigating the optimal use of TTh to enhance the sexual health of women with HSDD, and further studies on the long-term effects of testosterone use must be undertaken to ensure that patients have access to safe and effective treatment.

STRENGTHS AND LIMITATIONS

Limitations to this study include patient de-identification and lack of availability of testosterone dosage data. However, this study also has many strengths, including being the first, to our knowledge, to characterize the prescribing trends of testosterone for women with HSDD.

CONCLUSION

Testosterone therapy should be considered as a potential therapy for premenopausal female patients with HSDD. Further studies on the long-term effects of testosterone use must be undertaken to address disparities in the management of HSDD and to ensure patients can access treatment.

Management of hypoactive sexual desire dysfunction at a specialized service in women's sexual health

Hypoactive sexual desire dysfunction (HSDD) is prevalent among women. This retrospective cohort study aimed to verify the results of the strategies used by Gynecologists and Obstetricians (Ob-gyn) residents in the management of female HSDD. For this, we conducted a data collection of patient medical records of women with HSDD from the Human Sexuality Studies outpatient clinic of the Human Reproduction Center, Department of Gynecology and Obstetrics of FMRP-USP, from 2005 to 2019. Among the 437 women included, 361 (82.6%) answered the question concerning the effect of the protocol to which they were submitted, whereas 234 (64.8%) reported improvements in sexual desire. The univariate model showed that patients without chronic pelvic pain were 19.0% less likely to report improvements in HSDD than those with chronic pelvic pain (p = 0.03). Patients without depression and without orgasmic dysfunction were, respectively 32% and 23% more likely to show improvements in their HSDD than those who had depression or orgasmic dysfunction (respectively p = 0.001, p = 0.008). However, the multivariate model did not identify any associations. The assistance regarding HSDD by the Ob-gyn resident in training to deal with female sexual complaints may be effective in improving sexual complaints.

Sexual counseling for female sexual interest/arousal disorders: a randomized controlled trial based on the "good enough sex" model

BACKGROUND

Female sexual interest/arousal disorder (FSIAD) is the most common female sexual disorder with adverse effects on women's health and interpersonal relationships.

AIM

This survey evaluated the effects of sexual counseling based on the "good enough sex" (GES) model on the sexual health variables of women with FSIAD.

METHODS

A randomized clinical trial with a 1:1 allocation ratio was conducted among 80 women with FSIAD in Iran in 2021. Eligible participants were randomly assigned to group A (women) and group B (couples). Women attended 4 weekly online group sexual counseling sessions based on the GES model, each lasting 120 minutes. In group B, husbands participated in sessions 2 and 3.

OUTCOMES

Women's sexual health parameters-including sexual desire, sexual satisfaction, sexual function, sexual distress, sexual communication, frequency of sexual intercourse, and dysfunctional beliefs-were evaluated before and 3 months after counseling. The significance threshold considered P < .007 due to Bonferroni correction.

RESULTS

After the intervention, all sexual parameters except sexual dysfunctional beliefs showed significant improvement (P < .001) in both groups. During the follow-up period, the average scores for all sexual variables were slightly higher in group B vs group A. The between-group difference was significant only for frequency of sexual intercourse (P < .01).

CLINICAL IMPLICATIONS

This study reaffirms the impact of the GES model as biopsychosocial therapy in managing female sexual problems. Considering men's reluctance to accompany their wives to sex clinics, counseling for women alone can play a significant role in solving sexual problems, especially in the case of FSIAD. Online sexual consultation offers cost and time savings, provides a secure space for discussing sensitive topics, and facilitates group program coordination. It ensures universal access to counseling, thereby addressing gender incompatibility issues. It is a powerful, interactive, and acceptable alternative to in-person visits, providing convenience and confidentiality for clients seeking sexual health support.

STRENGTHS AND LIMITATIONS

The following were among the survey strengths: conducting a randomized controlled trial on women with FSIAD by applying an appropriate model and scales, involving spouses, and evaluating online group sexual counseling. However, the results of this study may not be generalizable to women without partners.

CONCLUSION

The GES model, emphasizing intimacy and sexual dialogue, reduces unrealistic sexual expectations and improves women's sexual desire and overall health. Our results showed that instead of insisting on the physical presence of husbands in counseling sessions, clinicians should emphasize their emotional support and companionship during the treatment process.

Guideline No. 443a: Opioid Use Throughout Women's Lifespan: Fertility, Contraception, Chronic Pain, and Menopause

OBJECTIVE

To provide health care providers with the best evidence on opioid use and women's health. Areas of focus include general patterns of opioid use and safety of use; care of women who use opioids; stigma, screening, brief intervention, and referral to treatment; hormonal regulation; reproductive health, including contraception and fertility; sexual function; perimenopausal and menopausal symptoms; and chronic pelvic pain syndromes.

TARGET POPULATION

The target population includes all women currently using or contemplating using opioids.

OUTCOMES

Open, evidence-informed dialogue about opioid use will lead to improvements in patient care and overall health.

BENEFITS, HARMS, AND COSTS

Exploring opioid use through a trauma-informed approach offers the health care provider and patient with an opportunity to build a strong, collaborative, and therapeutic alliance. This alliance empowers women to make informed choices about their own care. It also allows for the diagnosis and possible treatment of opioid use disorders. Use should not be stigmatized, as stigma leads to poor "partnered care" (i.e., the partnership between the patient and care provider). Therefore, health care providers and patients must understand the potential role of opioids in women's health (both positive and negative) to ensure informed decision-making.

EVIDENCE

A literature search was designed and carried out in PubMed and the Cochrane Library databases from August 2018 until March 2023 using following MeSH terms and keywords (and variants): opioids, illicit drugs, fertility, pregnancy, breastfeeding, and aging.

VALIDATION METHODS

The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations).

INTENDED AUDIENCE

All health care providers who care for women.

TWEETABLE ABSTRACT

Opioid use can affect female reproductive function; health care providers and patients must understand the potential role of opioids in women's health to ensure informed decision-making.

When the brain turns on with sexual desire: fMRI findings, issues, and future directions

INTRODUCTION

More than 2 decades of neuroimaging research has sought to uncover the neurologic basis of sexual desire. However, the lack of a clear conceptual distinction between sexual desire and sexual arousal or even a broadly accepted definition of sexual desire has led to confusion in the literature regarding brain areas uniquely associated with sexual desire.

OBJECTIVES

(1) To critically review the neuroimaging literature that seeks to identify brain areas and networks involved in sexual desire; (2) to identify and discuss those brain areas and potential networks that are most promising for providing insights to sexual desire; and (3) to offer recommendations for future studies.

METHODS

Existing meta-analyses were used as a starting point to identify relevant neuroimaging studies on sexual desire, arousal, and love. This base was then expanded via Google Scholar and forward citation tracking of already identified studies.

RESULTS

Brain areas that are commonly associated with sexual desire and arousal include the amygdala, hypothalamus, dorsal and ventral striatum, anterior cingulate, insula, and prefrontal and orbitofrontal cortex. However, because the same basic paradigm has been used to study sexual desire and arousal, unambiguous conclusions regarding areas uniquely involved in sexual desire cannot be drawn. Moreover, the lack of connectivity analyses and a failure to acknowledge negative BOLD (blood-oxygen level dependent) significantly limit conclusions on the neural basis of sexual desire.

CONCLUSION

Five recommendations are made. First, stimulus types (ie, erotic vs sexually explicit) should be selected by the meaningful theoretical conceptualization of the constructs of interest. Second, participants should be provided with definitions of sexual desire, mental sexual arousal, and perceived genital sexual arousal, so they can choose which terms best describe their experience. Third, event-related designs should be used with caution when investigating sexual desire. Fourth, time series analyses should be used to identify both positive and negative BOLD. Fifth, connectivity analyses should be performed to identify brain networks.

Reproduction strategy of nocturnal marine molluscs: running for love

The cost of reproduction is the core driver of life history evolution in animals. This paper demonstrates that the cumulative distance moved and the duration of movement of sexually immature abalones, Haliotis discus hannai, kept in various male and female groups, were significantly higher than those of sexually mature individuals, except when kept in mixed cultures of mature males and females. After mixed-culture, sexually mature males moved significantly further and for a longer duration than mature female abalones, and even more so than mature male abalones of any other group. Examination of the LC-MS metabolomics of mature males cultured with sexually mature females (AM) and those cultured with sexually immature females (JM) showed that cyclic adenosine monophosphate (cAMP) acted as a differential metabolic biomarker. After 24-h uninterrupted sampling, the concentration of 5-HT and the expression levels of the 5-HT2 and 5-HT6 receptors in AM were significantly higher than those in JM. After further injection of 5-HT2 and 5-HT6 receptor antagonists, the concentrations of cAMP and PKA rose again, but the cumulative movement duration and distance of male abalones decreased significantly, showing that 5-HT was involved in the regulation of movement behavior of male abalones through the 5-HT2 and 5-HT6 receptor-activated cAMP-PKA pathways. The results demonstrated a significant increase in the movement endurance of mature male abalones cultured with mature females, providing a theoretical basis for understanding the adaptive life history strategies of abalones and suggesting ways to protect diverse benthic resources for abalones during the reproductive stage.

The Effect of Menopause on the Sexual Functions and Marital Adjustment of the Spouses

Background

This study was conducted as a cross-sectional descriptive study to determine the effect of menopause on the SFs and marital adjustment (MA) of the spouses.

Materials and Methods

The sample of the study consisted of a total of 254 people, 127 of whom were postmenopausal women and their spouses. The data were collected with the Descriptive Information Form, the Female Sexual Function Scale (FSFS), the Arizona Sexual Experiences Scale (ASES), and the Marital Adjustment Scale (MAS). The t-test, Mann-Whitney U-test, Kruskal-Wallis test, and correlation analysis were used in the analysis of the data.

Results

Sexual dysfunctions (SDs) were detected in 91.3% of women and 77.2% of men. MA was found to be low in 74.1% of the women. The relationship between the level of MA and the total mean score of the women's FSFS was found to be statistically significant (P < 0.05). In addition, the relationship between the presence of SD in the postmenopausal women and the mean ASES score in the husband was found to be statistically significant (P < 0.05). According to Spearman's rho correlation coefficient, the positive correlation between the total mean score of the MAS and the mean total score of the FSFS was weak (r = 0.290; P = 0.001), and the negative correlation between the mean score of the total score of the ASES was weak (r = -0.381; P = 0.000) which was found to be a relationship (P < 0.05).

Conclusion

In this study, it was determined that menopause affects the marriage and sexual adjustment of spouses negatively.

Multidisciplinary approach to the treatment of sexual dysfunction in couples using a biopsychosocial model

BACKGROUND

Given the complexity of the psychological and biological pathologies associated with sexual dysfunction, which affects at least a third of adult women and men worldwide, a multidisciplinary approach has been advocated.

AIM

To assess sexual functioning, relationship satisfaction, and mood stability pre- and post- treatment at the Loyola University Sexual Wellness Program.

METHODS

Couples attending the 6-week multidisciplinary Sexual Wellness Program provided consent and completed pre- and post- intervention assessments. Linear mixed effects models were used to estimate the mean change from baseline to first follow-up. A covariance matrix was used to account for dependency.

OUTCOMES

All patients completed self-reported surveys: Dyadic Adjustment Scale, PROMIS Sexual Function and Satisfaction Measures Brief Profile (Patient-Reported Outcomes Measurement Information), and International Index of Erectile Function.

RESULTS

There were 85 respondents: 42 men and 43 women. The mean age was 49.82 years (range, 25-77). The largest improvement was on the total Dyadic Adjustment Scale score, which increased by approximately 5.18 points (95% CI, 2.55-7.81). PROMIS scores for global satisfaction with sex life, erectile function, and interest in sexual activity significantly increased from baseline, while the vaginal discomfort score significantly declined. Overall the score for global satisfaction with sex life increased from baseline by approximately 5.57 points (95% CI, 3.03-8.10). On average, men reported a 4.33-point increase (95% CI, 0.04-8.62) in their International Index of Erectile Function score from baseline.

CLINICAL IMPLICATIONS

A multidisciplinary treatment approach focused on the couple positively affects a couple's relationship, including global satisfaction with sex life, relationship satisfaction, interest in sexual activity, and erectile function.

STRENGTHS AND LIMITATIONS

This study is one of the few to document the effects of a multidisciplinary treatment approach for both members of a heterosexual couple-male and female. Limitations include the narrow demographics and lack of a control group in our population. Furthermore, this was completed at 1 academic center.

CONCLUSION

These findings emphasize that multidisciplinary sexual therapy programs aimed at the couple can help address multiple aspects of sexual well-being.

Hormone therapy for sexual function in perimenopausal and postmenopausal women: a systematic review and meta-analysis update

IMPORTANCE

Distressing sexual problems are a common complaint of menopausal women. In 2013, a Cochrane review assessed the effect of hormone therapy on sexual function in menopausal women; however, new evidence has since been published, which should be considered.

OBJECTIVE

This systematic review and meta-analysis aims to update the evidence synthesis on the effect of hormone therapy, compared with control, on sexual function in perimenopausal and postmenopausal women.

EVIDENCE REVIEW

Thirteen databases and clinical trial registries (Cochrane Central Register of Controlled Trials, EMBASE, Medical Literature Analysis and Retrieval System Online, PsycINFO, Web of Science, Cumulative Index to Nursing and Allied Health Literature, Literatura Latino-Americana e do Caribe em Ciéncias da Saúde, Database of Abstracts of Reviews of Effects, ClinicalTrials.gov, International Clinical Trials Registry Platform, Iranian Registry of Clinical Trials, Chinese Clinical Trial Registry, ISRCTN) were searched from December 2012 to March 30, 2022. Backward reference searching on all retrieved full texts was also performed. Study quality was assessed using the Cochrane ROB.2 tool. Data were pooled in random-effect model meta-analyses, which included all studies identified in the present search and all studies previously included in the 2013 Cochrane review.

FINDINGS

Forty-seven randomized controlled trials (35,912 participants) were included in the systematic review, and 34 randomized controlled trials (15,079 participants) were included in the meta-analysis. The meta-analysis revealed that, in comparison to control, estrogen therapy (standardized mean difference [SMD], 0.16; 95% confidence interval [CI], 0.02 to 0.29; I2 = 59%; 2,925 participants, 16 studies), estrogen plus progestogen therapy (SMD, 0.11; 95% CI, -0.07 to 0.29; I2 = 65%; 2,432 participants, 7 studies), tibolone (SMD, 0.15; 95% CI, 0.02 to 0.28; I2 = 0%; 916 participants, 2 studies), and selective estrogen receptor modulators (SMD, 0.18; 95% CI, 0.06 to 0.30; I2 = 0%; 1,058 participants, 4 studies) may result in no effect to small benefit on sexual function composite score.

CONCLUSION AND RELEVANCE

Hormone therapy may slightly improve sexual functioning. This potential small benefit should be considered when discussing treatment options for other menopausal symptoms.

Sexual attraction to visual sexual stimuli in association with steroid hormones across menstrual cycles and fertility treatment

BACKGROUND

Steroid hormones (i.e., estradiol, progesterone, and testosterone) are considered to play a crucial role in the regulation of women's sexual desire and sexual attraction to sexual stimuli throughout the menstrual cycle. However, the literature is inconsistent, and methodologically sound studies on the relationship between steroid hormones and women's sexual attraction are rare.

METHODS

This prospective longitudinal multisite study examined estradiol, progesterone, and testosterone serum levels in association with sexual attraction to visual sexual stimuli in naturally cycling women and in women undergoing fertility treatment (in vitro fertilization, IVF). Across ovarian stimulation of fertility treatment, estradiol reaches supraphysiological levels, while other ovarian hormones remain nearly stable. Ovarian stimulation hence offers a unique quasi-experimental model to study concentration-dependent effects of estradiol. Hormonal parameters and sexual attraction to visual sexual stimuli assessed with computerized visual analogue scales were collected at four time points per cycle, i.e., during the menstrual, preovulatory, mid-luteal, and premenstrual phases, across two consecutive menstrual cycles (n = 88 and n = 68 for the first and second cycle, respectively). Women undergoing fertility treatment (n = 44) were assessed twice, at the beginning and at the end of ovarian stimulation. Sexually explicit photographs served as visual sexual stimuli.

RESULTS

In naturally cycling women, sexual attraction to visual sexual stimuli did not vary consistently across two consecutive menstrual cycles. While in the first menstrual cycle sexual attraction to male bodies, couples kissing, and at intercourse varied significantly with a peak in the preovulatory phase, (all p ≤ 0.001), there was no significant variability across the second cycle. Univariable and multivariable models evaluating repeated cross-sectional relationships and intraindividual change scores revealed no consistent associations between estradiol, progesterone, and testosterone and sexual attraction to visual sexual stimuli throughout both menstrual cycles. Also, no significant association with any hormone was found when the data from both menstrual cycles were combined. In women undergoing ovarian stimulation of IVF, sexual attraction to visual sexual stimuli did not vary over time and was not associated with estradiol levels despite intraindividual changes in estradiol levels from 122.0 to 11,746.0 pmol/l with a mean (SD) of 3553.9 (2472.4) pmol/l.

CONCLUSIONS

These results imply that neither physiological levels of estradiol, progesterone, and testosterone in naturally cycling women nor supraphysiological levels of estradiol due to ovarian stimulation exert any relevant effect on women's sexual attraction to visual sexual stimuli.

Female Sexual Dysfunction in Association with Sexual History, Sexual Abuse and Satisfaction: A Cross-Sectional Study in Hungary

Female sexual dysfunction (FSD) has a negative impact on women's quality of life, self-esteem, and physical health. The aim of the present study was to explore the prevalence and the factors associated with FSD using an online questionnaire. A cross-sectional survey was conducted among young adults (18-35 years old) in Hungary using the DSM-5 criteria. The participants (n = 5942) were divided into three major groups: FSD (20.3%), an intermediate group (43.9%), and a control group (35.6%). Most of the women showing FSD were affected with female orgasmic disorder (9.2%) and genito-pelvic pain/penetration disorder (4.6%), while female sexual interest/arousal disorder was found in altogether 100 women (1.7%); 4.8% of women were affected by more than one definite disorder. The occurrence of female sexual dysfunction was related to the women's previous sexual history (first sexual experience, sexual education, early encounter with pornographic content, and sexual abuse), their self-satisfaction (with their own body, genitalia, and sexual attraction), and their sexual orientation. Sexual dysfunction showed a strong association with abuse, sexually transmitted diseases, and self-esteem. The present study identified the relationship between sexual dysfunctions and other health conditions, which can be the basis for some form of screening and early assistance programs for FSD.

[Efficacy and safety of testosterone in the treatment of hypoactive sexual desire in women: what does the evidence say?]

OBJECTIVE

To determine the efficacy and safety of testosterone in the treatment of hypoactive sexual desire in women.

MATERIALS AND METHODS

A systematic review of the literature was carried out in different electronic databases (CINAHL, DynaMed, EMBASE, Lilacs, Medline, Scopus, among others), between January 1990 and May 2021; through standardized search terms. The outcomes evaluated included the efficacy and safety of testosterone in increasing sexual desire, the total number of satisfactory sexual activity, the number of orgasms and the level of distress in patients with hypoactive sexual desire and the proportion of adverse reactions.

RESULTS

72 articles were included. The use of testosterone, in postmenopausal women, with hypoactive sexual desire, reports a positive effect on sexual function, with significant increases in satisfactory sexual activity, as well as improvement in all domains of sexual function (desire, arousal and orgasmic response) and a decrease in personal anguish, with an increase in the Female Sexual Function Index score. In women of childbearing age, testosterone is formulated for "off-label" use, in such a way that compounds and doses designed for treatments in men or magisterial formulas are used (which are not approved by consensus groups or endorsed by research), but has not shown any effect on sexual function. The most frequent adverse reactions are usually hirsutism and acne, although in general testosterone, at physiological doses, has a favorable safety profile.

CONCLUSIONS

Testosterone is an effective and safe therapy in the treatment of hypoactive sexual desire disorder in women after menopause. Currently there are no studies available to support the use of testosterone therapy in women of reproductive age, therefore, its use is not approved.

Pharmacotherapy for female sexual dysfunctions (FSDs): what is on the market and where is this field heading?

INTRODUCTION

Female sexual dysfunctions (FSDs) are common in women of any age and have a huge impact on quality of life and relationships. They have a multifaceted etiology limiting the development of pharmacotherapies with a high rate of effectiveness. Safety issues are also a concern.

AREAS COVERED

The authors report the most recent advances in pharmacotherapy for premenopausal and postmenopausal women with a main focus on hypoactive sexual desire disorders (HSDD) and associated sexual symptoms. Good levels of evidence have emerged for psychoactive agents, such as flibanserin and bremelanotide, as well as hormonal compounds (transdermal testosterone). The authors also report briefly on intravaginal DHEA (prasterone), local estrogen therapy (LET), and ospemifene to manage effectively vulvovaginal atrophy/genitourinary syndrome of menopause (VVA/GSM). In addition, they discuss promising therapeutic options highlighting the main reasons that hamper the availability of new labeled products. Finally, they include the importance of the multimodal approach to address FSDs.

EXPERT OPINION

Approved pharmacotherapies for FSD are limited. Validated multidimensional instruments and adequate objective measures of physical and mental responses to sexual external and internal incentives are mandatory to identify women suitable to chronic or on-demand treatments and to assess their pattern of response in research and practice.

Relationship between personality traits and sexual function in symptomatic postmenopausal women

INTRODUCTION

Female sexual function relies on a complex interplay of physical, psychosocial, and neurobiological factors. Over the last decades, increasing attention has been paid to the influence of personality traits on general health and many aspects of quality of life, including sexuality.

OBJECTIVE

To assess whether dimensions of the personality are related to the domains of sexual function (desire, arousal, lubrication, orgasm, satisfaction, and pain) in symptomatic postmenopausal women. Mood was also investigated to explore its association with female sexual dysfunction (FSD).

METHODS

Validated questionnaires to assess sexual function [the Female Sexual Functioning Index (FSFI)], mood [the State-Anxiety Inventory (STAI), and Zung Self Rating Depression Scale (SDS)], and personality traits [the Tridimensional Personality Questionnaire (TPQ)] were filled in by 130 early postmenopausal women experiencing hot flushes (≥30/week).

RESULTS

61.5 % (n = 80) of the women had an FSFI total score lower than 26.55, the standard cut-off for FSD. A clinical state of anxiety was present in 53.8 % (n = 70), whereas only 12.3 % (n = 16) showed clinically relevant depressive symptoms. According to the FSFI cut-off score, women with sexual disorders had statistically significantly higher levels of anxiety, depression (p < 0.001 for both), and harm avoidance (HA) (p = 0.004) than women without such disorders. Significantly higher levels of anxiety were found in women in the lower quartile (LQ) of the distribution of the total FSFI score than in women in both the interquartile range (IQR) and in the upper quartile (UQ) (p < 0.05). Moreover, women in the UQ had a lower grade of depression and HA than others (p < 0.05). The Sobel test showed that the personality trait HA significantly mediated the relationship between anxiety and FSFI total score (Z = -2.19, p < 0.05) and between depression and FSFI total score (Z = -2.35, p < 0.05).

CONCLUSIONS

The present data suggest the personality trait HA is relevant to sexual function and mediates the impact of mood on FSD in symptomatic menopausal women. In clinical practice, the use of validated psychometric tools for mood screening is useful to establish appropriate diagnosis and treatment of sexual disorders in menopausal women. Moreover, the assessment of personality traits could provide additional information that directs clinicians towards an increasingly tailored and multidimensional treatment of FSD.

Melanocortin 4 receptor agonism enhances sexual brain processing in women with hypoactive sexual desire disorder

BACKGROUND

Hypoactive 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.

METHODS

Using 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.

RESULTS

MC4R 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.

CONCLUSION

These 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.

Post-COVID-19 menstrual abnormalities and infertility: Repercussions of the pandemic

While battling the life-threatening complications of COVID-19, its effect on the menstrual cycle and infertility has been somewhat ignored. This brief review aims on highlighting the importance of menstrual abnormalities being experienced during the post-COVID period and to make the clinicians aware about what to expect in regard of menstrual abnormalities by learning from various studies that have been conducted worldwide. This review article was written with systematic literature review with the help of data search machine such as PubMed, Scopus, Web of Sciences, and Google Scholar. A search strategy leads to the extraction of 160 related articles that after the removal of inappropriate and duplicate articles, 33 articles were selected for the review. To find other potentially relevant articles, the references of the extracted articles were thoroughly examined. The search was carried out using keywords including "COVID-19," "Menstrual abnormalities," and "Infertility." Using OR and AND, the keywords mentioned above were combined and then utilized in the search box of the databases. Articles published from January 2020 to September 2021 were included in this study. It includes worldwide data ranging from studies done in China, India, Ireland, Turkey, Jordan, and Germany. During the post-COVID period, there is a significant alteration in the sex hormones of females infected by COVID-19 which may manifest as menstrual cycle abnormalities such as decreased cycle length or prolonged menstrual cycle bleeding. It may also manifest as infertility due to ovarian failure due to suppression of ovarian function COVID-19 a novel coronavirus which is presently a pandemic has affected the world in manner reminding the world of 1918 Spanish flu. However, while battling the deadly pandemic, the clinicians should also be aware of the repercussions of the effect this infection has on multiple organs such as ovarian suppression leading to infertility, oligomenorrhea, or menorrhagia.

Female sexual dysfunctions: an overview on the available therapeutic interventions

INTRODUCTION

There are different types of female sexual dysfunctions (FSDs), and FSD in general has a high prevalence worldwide. Studies of FSD should consider it as a multifactorial disorder that has biological, psychological, environmental, and relational aspects. In this review we discuss the available therapeutic interventions for FSD.

EVIDENCE ACQUISITION

For the current narrative review the PubMed database was searched to identify all publications up to 30 March 2021 that were systematic reviews and meta-analyses which examined therapeutic interventions for FSDs based on the diagnostic classifications of ICD-10 and ICD-11.

EVIDENCE SYNTHESIS

Thirty systematic reviews and meta-analyses were included in this review. Hormone therapy (HT) and testosterone are effective to improve sexual desire in menopausal women. In these women HT and ospemiphene may improve pain during intercourse. Flibanserin may improve sexual desire and may reduce desire-related distress in premenopausal women. Bremelanotide is effective to improve desire, arousal, and orgasm scores. Evidence are still limited on the efficacy of psychoactive drugs, phosphodiesterase type 5 (PDE5), oxytocin, herbal drugs, and tibolone to treat FSDs. Psychological interventions such as cognitive-behavior therapy, mindfulness training, sensate focus, bibliotherapy are effective for the management of several different FSDs.

CONCLUSIONS

The management of FSDs may require multidisciplinary and interdisciplinary approaches. Pharmacological and nonpharmacological interventions appears to have potential as a treatment for FSDs, but there are currently no gold standards regarding recommended treatment modalities, and the duration, frequency, and intensity of therapy sessions.

The neurobiology of bremelanotide for the treatment of hypoactive sexual desire disorder in premenopausal women

Hypoactive sexual desire disorder (HSDD) is a common female sexual dysfunction and is estimated to affect approximately 10% of women in the United States. It has been suggested that HSDD is associated with an imbalance of hormone and neurotransmitter levels in the brain, resulting in decreased excitation, increased inhibition, or a combination of both. Evidence suggests neurotransmitters, including dopamine (DA), norepinephrine, and serotonin, as well as hormones such as estradiol and testosterone, contribute to female sexual desire and response. Current treatments for HSDD include psychotherapy, and two US Food and Drug Administration-approved medications for premenopausal women: flibanserin, a serotonin mixed agonist and antagonist, and bremelanotide, a melanocortin receptor (MCR) agonist. Melanocortins are endogenous neuropeptides associated with the excitatory pathway of the female sexual response system. MCRs are found throughout the body, including the brain. Bremelanotide is an MCR agonist that nonselectively activates several of the receptor subtypes, of which subtype 4 (MC4R) is the most relevant at therapeutic doses. MC4R is predominantly expressed in the medial preoptic area (mPOA) of the hypothalamus in the brain, and is important for female sexual function. Animal studies suggest that bremelanotide may affect female sexual desire by activating presynaptic MC4Rs on neurons in the mPOA of the hypothalamus, leading to increased release of DA, an excitatory neurotransmitter that increases sexual desire. This review presents what is known about the mechanism of action of bremelanotide in the context of treating HSDD.

Assessing the Burden of Illness Associated with Acquired Generalized Hypoactive Sexual Desire Disorder

Background:

Hypoactive sexual desire disorder (HSDD), which affects ∼10% of women in the United States, is defined as the persistent or recurrent deficiency/absence of sexual desire accompanied by personal distress. Although HSDD impacts patient quality of life and interpersonal relationships, the disorder often goes unaddressed or untreated. Recent studies of the burden of illness in women with HSDD, especially premenopausal women, are limited.

Materials and Methods:

A 45-minute web-based survey was designed to investigate the experience of women seeking treatment for HSDD and the impact of this disorder on several psychosocial aspects of women's lives. Women were recruited from an online panel of patients who participated in research studies for compensation. Validated questionnaires assessed sexual function (Female Sexual Function Index) and health-related quality of life (12-Item Short Form Survey [SF-12]), including mental and physical component scores.

Results:

A total of 530 women, aged ≥18 years, diagnosed with acquired generalized HSDD were included in the study. Premenopausal women indicated greater overall HSDD symptom burden compared with postmenopausal women. Patients with HSDD reported lower SF-12 scores compared with the general population. A multivariable regression analysis demonstrated that psychosocial factors influencing the burden of HSDD, including interference with their relationship with their partner (β = −0.18; p < 0.005), mental and emotional well-being (β = −0.23; p < 0.005), and household and personal activities (β = −0.23; p = 0.02), negatively affected SF-12 mental component scores.

Conclusions:

HSDD symptom burden was found to be negatively and statistically significantly associated with patients' mental health; the impact was greater among premenopausal women compared with postmenopausal women.

Female Reproductive Health Disturbance Experienced During the COVID-19 Pandemic Correlates With Mental Health Disturbance and Sleep Quality

The COVID-19 pandemic has adversely affected population mental health. Periods of psychological distress can induce menstrual dysfunction. We previously demonstrated a significant disruption in women's reproductive health during the first 6 months of the pandemic. The present study investigates longer-term reproductive and mental health disturbances. A cross-sectional online survey was completed by 1335 women of reproductive age in April 2021. It included validated standardized measures of depression (PHQ-9), anxiety (GAD-7) and sleep quality (PSQI). 581 (56%) of women reported an overall change in their menstrual cycle since the beginning of the pandemic. There was no change in median cycle length [28 days (28-30)] or days of menses [5 (4-5)], but there was a wider variability in minimum (p<0.0001) and maximum (p<0.0001) cycle length. There was a significant increase in heavy menstrual bleeding, painful periods and missed periods compared to pre-pandemic (all p<0.0001). 64% of women reported worsening pre-menstrual symptoms. Rates of severe depression, anxiety and poor sleep were more than double those from large scale representative community samples. Poor sleep quality was an independent predictor of overall change in menstrual cycle (OR=1.11, 95%CI 1.05-1.18), and missed periods (OR=1.11, 95%CI 1.03-1.19) during the pandemic. Increased anxiety was independently associated with a change from non-painful to painful periods (OR=1.06, 95%CI 1.01-1.11) and worsening of pre-menstrual symptoms (OR=1.06, 95%CI 1.01-1.07) during the pandemic. The COVID-19 pandemic continues to bear a significant impact on female reproductive health. Increased levels of psychological distress and poor sleep are associated with menstrual cycle disruption.

Sexual dysfunction with major depressive disorder and antidepressant treatments: impact, assessment, and management

INTRODUCTION

Sexual dysfunction (SD) is a symptom of depression in ≈70% of patients presenting with major depressive disorder (MDD). Antidepressant medications (AD) and adjunctive treatments may further contribute to SD and complicate evaluation and management.

AREAS COVERED

A systematic literature search of PubMed, Ovid MEDLINE and Cochrane databases for MDD, SD, classes of antidepressants, etc. was performed with a focus on 2014 to June 2021. SSRIs are associated with 70% treatment-emergent sexual dysfunction (TESD), SNRIs and tricyclics have rates of TESD of 40 - 45%, and antidepressant medications without SRI effects or with additional unique mechanisms of action have rates similar to placebo (<10%). Appropriate assessment at baseline and throughout treatment, consideration of patient preferences in prescribing, addressing modifiable factors (comorbid medical/psychiatric conditions, substances, relationship difficulties), and utilizing management strategies of switching to an AD with less SD, adding an antidote/adjunctive therapy or lowering the dose are discussed.

EXPERT OPINION

MDD and antidepressant treatment contribute to SD in a high percentage of patients. Treating to remission reduces SD as a symptom of depression. Frequent assessment and targeted management strategies may be effective in preventing or addressing SD. Secondary outcomes like impact on adherence, relationships and self-image should also be considered.

Prevalence of sexual dysfunction in depressive and persistent depressive disorders: a systematic review and meta-analysis

The aim of this study was to estimate the prevalence of sexual dysfunction in depressive disorders in individuals not in pharmacological treatment. For this purpose, we performed a systematic review and meta-analysis using the PRISMA guidelines, and the review was registered in PROSPERO (registration number CRD42020179709). Studies that evaluated sexual function and dysfunction in major depressive disorder (MDD) and persistent depressive disorder (PDD) were identified through searches in PubMed/Medline, Web of Science, PsychINFO, Scopus, and Scielo. Twelve cross-sectional studies were eligible. In women with MDD, the pooled prevalence rates of sexual impairment were: 47.22% (95% CI: 34.86-59.58) for arousal; 65.30% (95% CI: 45.86-84.73) for desire; 36.98% (95% CI: 28.42-45.54) for lubrication; 34.17% (95% CI: 17.87-50.46) for orgasm; and 33.91% (95% CI: 17.48-50.34) for sexual satisfaction. In men, the sexual impairment prevalence rates were: 26.45% (95% CI: 12.26-40.63) for arousal; 40.32% (95% CI: 22.19-58.46) for desire; 32.07% (95% CI: 26.14-37.99) for erection; 35.27% (95% CI: 5.13-65.41) for orgasm; and 23.05% (95% CI: 13.60-32.51) for sexual satisfaction. Overall sexual dysfunction was found in 82.75% of women (95% CI: 74.71-90.78) and 63.26% of men (95% CI: 52.83-73.69). Our results show that various sexual functions are impaired in MDD, making imperative the systematic evaluation of these alterations by clinicians. Future studies should be conducted, especially in PDD, to elucidate the role of these disorders in sexual function.

Safety Profile of Bremelanotide Across the Clinical Development Program

Background: Bremelanotide, a melanocortin receptor agonist, is Food and Drug Administration (FDA)-approved for the treatment of premenopausal women with acquired, generalized hypoactive sexual desire disorder. Methods: Review of bremelanotide's safety profile from the clinical development program (phases 1 through 3). Results: The clinical development program comprised 3500 subjects in 43 completed studies. In the phase 3 studies, subjects took bremelanotide for up to 18 months. The most common adverse events (AEs) were nausea (40.0% vs. 1.3%), flushing (20.3% vs. 1.3%), headache (11.3% vs. 1.9%), and injection site reactions (5.4 vs. 0.5), bremelanotide versus placebo groups, respectively, in the integrated double-blind portion of the phase 3 studies (N = 1247). Nausea was the most common reason for bremelanotide discontinuation. There were no deaths; a few subjects experienced serious AEs. Focal hyperpigmentation was rare when bremelanotide was dosed in accordance with label recommendations, but it occurred in more than one-third of subjects following up to 16 consecutive daily dosings. Small and transient but statistically significant blood pressure increases were observed during ambulatory blood pressure monitoring. Most drug-drug interactions were not clinically significant, except for interactions that lowered plasma concentrations of indomethacin and naltrexone. In the double-blind portion of the integrated phase 3 studies, 70% of the bremelanotide group proceeded to the open-label phase of the studies versus 87% of those on placebo. Conclusions: The AEs associated with bremelanotide are mostly mild to moderate. Although not deemed clinically important, bremelanotide should be used with caution in patients at risk of cardiovascular disease, and blood pressure should be well controlled during treatment. Clinical Trial Registration number: NCT02333071 [Study 301] and NCT02338960 [Study 302].

Italian Association of Clinical Endocrinologists (AME) and International Chapter of Clinical Endocrinology (ICCE). Position statement for clinical practice: prolactin-secreting tumors

Prolactinomas are the most frequent pituitary adenomas. Prolactinoma may occur in different clinical settings and always require an individually tailored approach. This is the reason why a panel of Italian neuroendocrine experts was charged with the task to provide indications for the diagnostic and therapeutic approaches that can be easily applied in different contexts. The document provides 15 recommendations for diagnosis and 54 recommendations for treatment, issued according to the GRADE system. The level of agreement among panel members was formally evaluated by RAND-UCLA methodology. In the last century, prolactinomas represented the paradigm of pituitary tumors for which the development of highly effective drugs obtained the best results, allowing to avoid neurosurgery in most cases. The impressive improvement of neurosurgical endoscopic techniques allows a far better definition of the tumoral tissue during surgery and the remission of endocrine symptoms in many patients with pituitary tumors. Consequently, this refinement of neurosurgery is changing the therapeutic strategy in prolactinomas, allowing the definitive cure of some patients with permanent discontinuation of medical therapy.

Clinically Meaningful Benefit in Women with Hypoactive Sexual Desire Disorder Treated with Flibanserin

Background

The efficacy of flibanserin in treating hypoactive sexual desire disorder (HSDD) is based upon statistically significant improvements in sexual desire, satisfying sexual events, and distress. However, clinically meaningful benefit has not been well characterized.

Aim

Evaluate clinically meaningful benefit of flibanserin.

Methods

Data were pooled from 3 pivotal trials evaluating flibanserin 100 mg qhs in premenopausal women (flibanserin, n = 1192; placebo, n = 1215). Flibanserin trial data in postmenopausal women (flibanserin, n = 450; placebo, n = 476) were analyzed separately. Clinically meaningful benefit was evaluated by the Patient Global Impression of Improvement (PGI-I). Responders were determined through anchor-based analyses that used the PGI-I for key efficacy endpoints: satisfying sexual events (SSE), desire domain of the Female Sexual Function Index (FSFI-d), and distress associated with decreased sexual desire (FSDS-R13). Odds ratios were calculated to assess effect size and Kaplan-Meier analyses were performed to estimate onset time for treatment benefit.

Outcomes

PGI-I, anchor-based analyses for key efficacy endpoints (SSE, FSFI-d, FSDS-R13), odds ratios, onset time for treatment benefit.

Results

Based on the PGI-I, more patients reported clinically meaningful benefit with flibanserin treatment versus placebo (49.8% vs 33.6%, premenopausal cohort; 40.5% vs 28.7%, postmenopausal cohort). In anchor-based analyses, responder rates were significantly higher for premenopausal women on flibanserin (46.1%–55.2%) than placebo (34.1%–44.2%) for all 3 key efficacy endpoints (P < .0001). Responder rates for postmenopausal women on flibanserin were higher compared to placebo for SSE (29.8% vs 22.9%; P = .015) and FSFI-d (38.9% vs 26.3%; P = .0001). Odds ratios for key endpoints indicated that premenopausal women were 2.0–2.4 times as likely to be responders with flibanserin treatment compared to placebo. Postmenopausal women were 1.6 times as likely to be responders with flibanserin for FSFI-d. Kaplan-Meier analyses indicated significant separation between flibanserin and placebo for the key endpoints in both premenopausal and postmenopausal cohorts (log-rank tests P < .01) with earlier median response times among patients receiving flibanserin.

Clinical Implications

Patient-reported benefit assessments such as the PGI-I capture the patient's perspective and may be a useful approach in assessing overall clinical meaningfulness for sexual dysfunction therapies.

Strengths and Limitations

Strengths include a well-powered study with large enrollment, use of validated instruments, and self-assessment of treatment benefit. Limitations include pooling of trial data in premenopausal women with slightly different study designs and use of an endpoint (SSE) indirectly related to HSDD.

Conclusion

Assessment of clinically meaningful benefit and additional responder analyses provide further support for flibanserin's efficacy beyond numerical improvements in endpoint measures.

Cognitive-behavioral group therapy for women with hypoactive sexual desire: A pilot randomized study

BACKGROUND

Hypoactive Sexual Desire Disorder (HSDD) is a very prevalent sexual problem, with limited options for treatment. Given that psychological factors are major contributors to the disorder, a therapy such as Cognitive-Behavioral Therapy (CBT) may be useful to treat HSDD.

OBJECTIVE

To evaluate the effects of group CBT on women with HSDD.

METHOD

Clinical trial randomized study with 106 women diagnosed with HSDD, who were divided as follows: Group 1 (n = 53) underwent group CBT for 8-weeks, and Group 2 (n = 53), were put on a waiting list and used as a control group. Sexual function was assessed by the Female Sexual Quotient (FSQQ) at the initial interview and after 6-months. Mann Whitney test was used for group comparison.

MAIN OUTCOME MEASURES

demographics, education, sexual history, FSQQ and its domains for sexual function assessment.

RESULTS

Both groups had similar characteristics regarding sexual response, self-image, and relationship with a partner at the initial interview. Women undergoing therapy showed significant improvement in sexual function when compared with the control group. The overall FSQQ result showed an average growth of 18.08 points (95% CI 12.87‒23.28) for the therapy group against a decrease of 0.83 points (95% CI 3.43‒1.77) for controls (p < 0.001). The five domains of the questionnaire also exhibited significant improvement in the therapy group: desire and interest (p = 0.003), foreplay (p = 0.003), excitation and tuning (p < 0.001), comfort (p < 0.001), and orgasm and satisfaction (p < 0.001).

CONCLUSION

Group CBT was shown to be an effective tool for treating HSDD.

Effects of testosterone treatment on clitoral haemodynamics in women with sexual dysfunction

PURPOSE

To explore the effects of 6-month systemic testosterone (T) administration on clitoral color Doppler ultrasound (CDU) parameters in women with female sexual dysfunction (FSD).

METHODS

81 women with FSD were retrospectively recruited. Data on CDU parameters at baseline and after 6 months with four different treatments were available and thus further longitudinally analyzed: local non-hormonal moisturizers (NH group), n = 37; transdermal 2% T gel 300 mcg/day (T group), n = 23; local estrogens (E group), n = 12; combined therapy (T + E group), n = 9. Patients underwent physical, laboratory, and genital CDU examinations at both visits and completed different validated questionnaires, including the Female Sexual Function Index (FSFI).

RESULTS

At 6-month visit, T therapy significantly increased clitoral artery peak systolic velocity (PSV) when compared to both NH (p < 0.0001) and E (p < 0.0001) groups. A similar increase was found in the T + E group (p = 0.039 vs. E). In addition, T treatment was associated with significantly higher FSFI desire, pain, arousal, lubrication, orgasm, and total scores at 6-month visit vs. baseline. Similar findings were observed in the T + E group. No significant differences in the variations of total and high-density lipoprotein-cholesterol, triglycerides, fasting glycemia, insulin and glycated hemoglobin levels were found among the four groups. No adverse events were observed.

CONCLUSION

In women complaining for FSD, systemic T administration, either alone or combined with local estrogens, was associated with a positive effect on clitoral blood flow and a clinical improvement in sexual function, showing a good safety profile.

A higher quality of life by the Cervantes Short-Form Scale is related to a better sexual desire in postmenopausal women

OBJECTIVE

Evaluate the association between health relate quality of life and sexual desire in postmenopausal women and the influence of demographic descriptors on sexual desire.

METHODS

A observational-cross-sectional study was conducted in 521 postmenopausal women in La Zarzuela Hospital between 2018-2020. Cervantes-short form (Cervantes-SF) scale and Brief profile female sexual function (B-PFSF) scale were filled out in the consultation. High score in Cervantes-SF implies worse health-related quality of life (HR-QoL). If score is lower or equal to 20 in B-PFSF implies diagnosis of hypoactive sexual desire disorder.

RESULTS

There is a positive relationship between HR-QoL measured by Cervantes-SF and sexual desire measured by B-PFSF (p < .001; correlation coefficient: .223). The mean score on Cervantes-SF was 30.8 ± 14.9 and on B-PFSF was 18.7 ± 7.4. The B-PFSF score was worse in those women using systemic or vaginal hormonal treatment versus using non-hormonal treatment (18.7 ± 7.8 or 17.2 ± 7.4 vs 19.7 ± 6.5; p = .033. Smoking (b exp: .384; p = .029) and using vaginal hormonal treatment (b exp: 1.759; p = .033) are independent factors related to sexual desire. No difference was found in the wellbeing perceived by women in the different treatments (mean of minimal clinically important difference score was 2.9 in systemic vs. 3.0 in vaginal hormonal treatment).

CONCLUSIONS

Improvement on HR-QoL is related to improvement on sexual desire. Sexual desire is better in women with non-hormonal treatment than in women with systemic or vaginal hormonal treatment. The vaginal hormonal treatment and being current smoker are independent factors of low and high sexual desire, respectively.

Oncology Survivorship and Sexual Wellness for Women

Sexual dysfunction is extremely common in cancer survivors. Cancer survivors are living longer, and survivorship issues like sexual functioning are now a part of routine cancer care. Oncology providers need to be as comfortable assessing and addressing these issues as they would any other aspect relating to cancer care. Providers should know how to perform an evaluation for sexual dysfunction, understand basic treatment options, and have appropriate referrals available to ensure that the patient's needs are met. This review provides an overview of sexual dysfunction pertaining to women who are survivors of cancer and articulates areas needing further research.

Hypoactive Sexual Desire Disorder in Women: Physiology, Assessment, Diagnosis, and Treatment

Nearly half of women in the United States report problems with sexual function. Many health care providers do not ask about sexual concerns during routine clinical encounters because of personal discomfort, lack of familiarity with treatment, or the belief that they lack adequate time to address this complex issue. This may be especially true for hypoactive sexual desire disorder (HSDD), the most commonly identified sexual problem among women. HSDD is characterized by a deficiency of sexual thoughts, feelings, or receptiveness to sexual stimulation that has been present for at least 6 months, causes personal distress, and is not due to another medical condition. This is an up-to-date overview of HSDD for clinicians, discussing its physiology, assessment, diagnosis, and treatment strategies. Although a definitive physiology of HSDD is still unknown, multiple hormones and neurotransmitters likely participate in a dual-control model to balance excitation and inhibition of sexual desire. For assessment and diagnosis, validated screening tools are discussed, and the importance of a biopsychosocial assessment is emphasized, with guidance on how this can be implemented in clinical encounters. The 2 recently approved medications for HSDD, flibanserin and bremelanotide, are reviewed as well as off-label treatments. Overall, HSDD represents a common yet likely underrecognized disorder that midwives and other health care providers who care for women across the life span are in a unique position to address.
