Prevalence and risk of developing sexual dysfunction in women with multiple sclerosis (MS): a systematic review and meta-analysis

Sexual dysfunction in female patients with multiple sclerosis: relationship with functional status, fatigue, depression, sleep quality, and quality of life

BACKGROUND

Although sexual dysfunction is one of the most common symptoms in patients with multiple sclerosis (MS), there are relatively few studies on this topic.

AIM

The aim of this study was to assess sexual function in female MS patients and investigate its association with functional state, fatigue, depression, sleep, and quality of life.

METHODS

This descriptive cross-sectional study was conducted between May and November 2019 with MS patients attending an MS outpatient clinic at a university hospital. Patients' sexual function was assessed using the Female Sexual Function Index (FSFI). Expanded Disability Status Scale (EDSS), Fatigue Severity Scale (FSS), Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), and Multiple Sclerosis Quality of Life Scale (MSQoL-54) were used to determine their relationship to sexual function.

OUTCOMES

Sexual function, functional status, depression, sleep quality, and quality of life.

RESULTS

The mean age of the 83 patients included in the study was 41.8 (±8.5) years, and all were married. The mean FSFI score of the patients was 21.1 (±8.9) and 26.55, 72.3% of patients were found to have sexual dysfunction. FSFI scores were found to have a negative correlation with age (r = -0.398, P = .001), duration of diagnosis (r = -0.338, P = .001), and EDSS scores (r = -0.326, P = 0.040). Patients taking symptomatic medication (P = .032) and antidepressants (P = .012) had lower mean FSFI scores. Additionally, the FSFI score showed a significant negative correlation with the FSS (r = -0.368, P = .001), the BDI (r = -0.423, P < .001), the PSQI (r = -0.314, P = .004), and the MSQoL-54 (physical health: r = 0.509, P < .001 and mental health: r = 0.431, P < .001).

CLINICAL IMPLICATIONS

A comprehensive evaluation of sexual dysfunction and the development of tailored treatment plans, taking into account associated factors, will be beneficial for female patients with MS.

STRENGTHS AND LIMITATIONS

Small sample size and assessment of sexual function by a generic scale are the limitations of this study.

CONCLUSION

Considering the multifactorial nature of sexual dysfunction in female MS patients, it is recommended that patients be assessed multidimensionally during outpatient follow-up visits.

Association of disability, walking, manual dexterity, and quality of life with sexual dysfunction in multiple sclerosis patients

BACKGROUND/OBJECTIVE

This study aims to examine the relationship between sexual dysfunction and walking ability, manual dexterity, disability, and quality of life in patients with multiple sclerosis.

METHODS

51 sexually active MS patients (28 females and 23 males) participated in the study. Demographic data were recorded for all patients. We used the Female Sexual Function Index (FSFI) and the International Index of Erectile Function (IIEF) to assess sexual function, the Expanded Disability Status Scale (EDSS) to determine disability, the SF-36 to assess quality of life, the Nine-Hole Peg test (9-HPT) to evaluate manual dexterity, and the Timed 25-Foot Walk test (T25FW) to assess walking ability.

RESULTS

Sexual dysfunction was found in 92.9% of females and 73.9% of males. Common issues in females included decreased sexual desire, decreased sexual arousal, and lubrication and orgasm problems, while males reported erectile dysfunction, decreased sexual desire, and decreased intercourse satisfaction. Significant correlations were observed between FSFI and SF-36 scores in females and between IIEF scores and the 9-HPT, EDSS, and SF-36 scores in males.

CONCLUSIONS

Sexual dysfunction is common among both male and female MS patients and is associated with disability, manual dexterity, and quality of life. Raising awareness is essential to support appropriate treatment approaches and improve the quality of life for these patients.

Sexual dysfunction and quality of life across age groups in multiple sclerosis patients: a prospective cross-sectional analysis

INTRODUCTION

As the most frequent chronic neurological disorder in young adults, Multiple sclerosis (MS) significantly affects neurological function, particularly the autonomic nervous system. While the physical symptoms are visible, MS also causes hidden effects like sexual dysfunction. Research indicates that sexual disorders are more prevalent in MS patients compared to other neurological conditions and are approximately five times more common than in the general population. This study utilized the Sexual Intimacy and Desires in MS Patients Questionnaire (MSISQ-19) and the Quality of Life in Patients with Multiple Sclerosis Questionnaire to investigate the impact of sexual disorders on the quality of life in MS patients.

METHODS

This cross-sectional study was conducted on MS patients attending the MS clinic in 2022 and 2023. Eighty patients were randomly selected, and data were collected using the MSISQ-19 and MSQOL-54 questionnaires. The results were analyzed to establish the impact of sexual disorders on quality of life.

RESULTS

59 women and 21 men with MS were included. The Physical Health Scale (PHC) had a mean score of 51.6 (SD = 20.2), and the Mental Health Scale (MHC) had a mean score of 57.8 (SD = 20.5). Age appeared to influence physical health scores, with the youngest group (20-30 years) scoring highest and the oldest group (51-65 years) scoring lowest.

DISCUSSION AND CONCLUSION

The present study found that primary, secondary, and tertiary sexual disorders are common in MS patients across all age groups and genders. These findings highlight the need for increased attention, research, and treatment interventions for sexual dysfunction in MS patients.

Comparison of different telerehabilitation protocols for urogenital symptoms in females with multiple sclerosis: a randomized controlled trial

Telerehabilitation has been suggested to be equally effective than in-person rehabilitation, and could be helpful to increase participation and reduce barriers. People with multiple sclerosis (MS) often present urogenital dysfunctions, impairing independence and quality of life (QoL). Since the different available telerehabilitation protocols, the present study aimed to compare a live video urogenital rehabilitation intervention protocol (REMOTE) with a home-based pre-recorded video protocol (SELF). A randomized-controlled trial was performed, with 14 females with MS being allocated in the REMOTE group (36 ± 9 y) and 14 females in the SELF group (37 ± 7 y). Both telerehabilitation protocols were identical in terms of contents (including pelvic floor training and relaxation exercises), frequency and duration, consisting of 10 sessions of 45 min each, every 5 days. Questionnaires were administered at the beginning and the end of the study: Short Form Health Survey 36 (SF-36), Beck Depression Inventory (BDI), Female Sexual Function Index (FSFI), International Consultation on Incontinence Questionnaire (ICIQ) symptoms and related QoL, the main outcome being ICIQ incontinence score. Despite most of the outcomes improved in both groups, REMOTE was found to be more effective than SELF in most of the SF-36 domains (from p < 0.001 pη2 0.555 to p = 0.044 pη2 0.147), FSFI (p = 0.001 pη2 0.373), ICIQ (p = 0.003 pη2 0.291). Despite the home-based pre-recorded videos could be effective in improving urogenital symptoms, live video urogenital rehabilitation results in larger improvements. Telerehabilitation should be encouraged for urogenital dysfunctions in females with MS, and pre-recorded videos could represent an alternative when live sessions are not available. Clinical trial registration This randomized controlled trial was registered on ClinicalTrials.gov with the number NCT05984095.

Percutaneous Tibial Nerve Stimulation's Impact on Sexual Function in Female Patients with Neurogenic Detrusor Overactivity, Sexual Dysfunction, and Multiple Sclerosis

Background/Objectives: Multiple sclerosis (MS) frequently results in both urinary and sexual dysfunction, which significantly impairs quality of life. Conventional treatments for bladder dysfunction often prove insufficient, leading to the exploration of alternative therapies such as percutaneous tibial nerve stimulation (PTNS). This study aimed to assess the impact of PTNS on sexual function and bladder symptoms in female MS patients with neurogenic detrusor overactivity (NDO) and female sexual dysfunction (FSD). Methods: A total of 65 female MS patients with NDO were evaluated and underwent 12 weeks of standardized PTNS treatment. Sexual function was assessed using the Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale-Revised (FSDS-R), while bladder symptoms were evaluated using the OAB-v8 questionnaire. Participants were grouped based on the presence of sexual dysfunction and distress and compared to a control group of 20 patients who declined PTNS. Results: Significant improvements were observed in FSFI scores across multiple domains (desire, arousal, lubrication, orgasm, satisfaction, and pain) in the treatment groups (p < 0.05). Additionally, 58.46% of patients showed positive responses to PTNS regarding overactive bladder symptoms (OAB-v8 score), while the control group showed no significant changes. Conclusions: PTNS appears to be an effective therapeutic option for improving sexual function and urinary symptoms in female MS patients with NDO and FSD, offering a promising non-invasive alternative for managing these conditions.

Diversity and representation within the literature on sexual dysfunction in multiple sclerosis: A systematic review

INTRODUCTION

Sexual dysfunction (SD) is a common and distressing symptom for people living with multiple sclerosis (MS). Populations included in existing studies of SD may not fully reflect the diversity of people living with MS, with important implications for wider applicability. We aimed to evaluate reporting of sex, gender identity, sexual orientation, and ethnicity across studies of SD in MS.

METHODS

A systematic search of four databases was performed. Two independent authors evaluated all papers. Reporting of sex and gender identity, sexual orientation, and ethnicity were recorded.

RESULTS

A total of 419 papers were reviewed, and 204 studies with 77,902 participants met the criteria for evaluation. Of 204 studies, 98 (48.0%) included both male and female participants; 78 (38.2%) included females only, and 27 (13.2%) males only. In 19 (9.3%) studies, participants were asked their gender. No studies reported asking a two-step question on sex and gender identity. No studies reported including non-binary patients or gender identities other than male or female. No studies reported including intersex patients. Only 10 (4.9%) studies reported the inclusion of homosexual or bisexual participants, or participants from other sexual minority groups. The overwhelming majority of studies (181; 88.7%) did not report ethnicity or race of participants.

CONCLUSION

Sex, gender identity, sexual orientation, and ethnicity are poorly reported in studies on SD in MS. These variables must be adequately evaluated to ensure research applies across diverse MS patient populations.

YouTube Videos Are a Moderately Comprehensive, Reliable, and Quality Option to Learn About "Multiple Sclerosis and Sexuality"

Objectives

This study aimed to evaluate the performance, comprehensiveness, reliability, and quality of English-language YouTube videos addressing the subject of multiple sclerosis and sexuality.

Methods

In August 2023, a search was conducted on a computer using the keywords "multiple sclerosis and sexuality," "multiple sclerosis and sexual health," "multiple sclerosis and sexual health problems," and "multiple sclerosis and sexual dysfunction" for this descriptive study. According to predetermined inclusion and exclusion criteria, 38 videos that met the research purpose were examined. The related URLs were recorded. For each video, the following information was collected: content producers, performance with YouTube statistics, comprehensiveness with a form developed by researchers, reliability with Singh's Reliability Evaluation Form, and quality with Global Quality Scale. Two researchers independently evaluated the videos.

Results

Eighty-nine and a half percent of the videos contained information presented by professionals. The average number of views was 2699.132 ± 3382.848, the comprehensiveness score was 4.2 ± 1.711, the reliability score was 3.184 ± 1.182, and the quality score was 3.421 ± 1.2. Nearly half (42.2%) contained good and useful information for viewers, and half (50%) had high video quality. The reliability and quality scores of videos containing each item in terms of comprehensiveness were higher compared to videos that did not include that item (p < 0.05). In addition, the videos with higher comprehensiveness scores had higher quality and reliability scores (p < 0.001).

Conclusion

These results underscore the constrained performance attributes of YouTube videos addressing multiple sclerosis and sexuality, with their content exhibiting a moderate level of comprehensiveness, reliability, and quality. These results may provide a basis for increasing the effectiveness of YouTube videos on multiple sclerosis and sexuality.

Priority setting: women's health topics in multiple sclerosis

Background

A scoping review found that most studies on women's health in multiple sclerosis (MS) focused on pregnancy, fetal/neonatal outcomes and sexual dysfunction. Few studies addressed menopause, contraception, gynecologic cancers/cancer screening. However, the perceived relative importance of these knowledge gaps to people living with MS and other partners is unknown. We engaged a range of partners, including people living with MS, health care providers, researchers, and patient advocacy groups, to set priorities for future research in women's health in MS.

Methods

We employed a three-step global engagement process. First, we identified which broad research topics relevant to women's health in MS were of highest priority using two surveys. Second, we developed specific research questions within these topics using focus groups. Finally, we prioritized the research questions with a third survey.

Results

Overall, 5,266 individuals responded to the initial surveys [n = 1,430 global survey, mean (SD) age 50.0 (12.6), all continents; n = 3,836 North American Research Committee on Multiple Sclerosis survey, mean (SD) age 64.8 (9.6), United States]. Menopause, sexual dysfunction, pregnancy, gynecologic cancer/cancer screening, hormones and parenthood were identified as the most important topics. Focus groups generated 80 potential research questions related to these topics. In the final survey 712 individuals prioritized these questions. The highest priority questions in each research topic were: (i) How do perimenopause and menopause affect disease activity, course, response to disease-modifying treatment and quality of life in MS; (ii) What are the most effective strategies for managing issues around sexual intimacy, including related to low sexual desire, changes in physical function, and MS symptoms; (iii) Are there long-term effects of disease-modifying therapies on the children of persons with MS; (iv) What are the short and long-term effects of disease-modifying drugs on gynecologic cancer risk, particularly for high efficacy disease-modifying drugs and hematopoietic stem cell transplantation; (v) Are there hormone related treatments that can stabilize fluctuations in MS symptoms; and (vi) How does MS fatigue impact parenting strategies.

Conclusion

Priorities for research relating to women's health issues for persons with MS have been delineated using a collaborative process with key partners. Alignment of future research with these priorities should be monitored.

Supervised Pelvic Floor Muscle Training Improves Sexual Function and Diminishes Sexual Distress in Women with Relapsing-Remitting Multiple Sclerosis: A Randomised Controlled Study

This study investigates the impact of pelvic floor muscle training (PFMT) on sexual function and distress in women with multiple sclerosis (MS), a prevalent chronic nervous system disorder associated with sexual dysfunction. This study's primary aim was to assess the effectiveness of PFMT at improving sexual function and alleviating sexual distress in this population. In a randomised controlled trial, 82 women with MS were divided into two groups: Group A (41 women) underwent 12 weeks of PFMT, while Group B (41 women) served as a control group with no intervention. Both groups were assessed at the beginning and end of this study using the Female Sexual Function Index (FSFI) and Female Sexual Distress Scale-Revised (FSDS-R). Statistical analysis, including Chi-square tests, was employed to compare the outcomes between the two groups, with a p-value of less than 0.05 considered significant. The results revealed no significant differences in baseline sexual function and distress between the groups. However, at the conclusion of the 12-week period, Group A exhibited statistically significant improvements in nearly all domains of FSFI and FSDS-R compared to Group B, except in the pain domain. This study concludes that PFMT can effectively enhance sexual function and reduce sexual distress in women suffering from MS. These findings underscore the potential of PFMT as a therapeutic intervention in managing sexual dysfunction associated with MS.
