Sexual function in patients with endometriosis: a prospective case-control study in China

A Systematic Review of the Psychosocial Impact of Endometriosis before and after Treatment

While endometriosis is a common gynecologic disease associated with infertility, the psychosocial impact of endometriosis has not been evaluated against various quality of life (QoL) instruments and compared with other chronic illnesses. We rigorously analyzed the psychosocial burden of endometriosis in adult women and compared standardized and validated QoL scores of women with and without endometriosis, before and following treatment, and against other chronic illnesses. We searched PubMed, PsychINFO Embase, and Cochrane Reviews and ClinicalTrials.gov from January 1990 to December 2022 for publications using a detailed list of search terms related to QoL, endometriosis, and questionnaires. Only English-language publications that evaluated the association between Endometriosis and QoL using standardized and validated questionnaires measured at baseline and following treatment were considered. Four reviewers first performed a title and abstract screening followed by full text-review to finalize included articles. QoL scores of women with endometriosis were measured at baseline and analyzed against women without endometriosis and women with endometriosis who had undergone treatment. Additionally, baseline endometriosis scores were assessed against the published QoL scores of populations with other chronic conditions. Assessment of risk of bias was performed in accordance with Cochrane and Newcastle-Ottawa Scale guidelines. A total of 30 articles were included in this review: 4 randomized trials and 26 observational studies. The diagnosis and experience of women with symptomatic endometriosis had an equal or worse QoL score than that of other chronic conditions including heart disease, diabetes, and breast cancer when compared using the 36-Item Short Form Survey and World Health Organization Quality of Life questionnaires. Evidence showed association between low QoL and infertility, sexual dysfunction, mental health struggles, physical pain, poor sleep and fatigue. QoL scores were lower at baseline compared to following treatment in the majority of these domains. Endometriosis is associated with significant psychosocial burden and impaired QoL scores across baseline measurements in comparison to controls and other chronic illnesses. Medical and surgical interventions significantly decreased experienced burdens and improved QoL of women with endometriosis.

Measurement properties of sexual function assessment questionnaires in women with endometriosis: A systematic review following COSMIN guidelines

INTRODUCTION

Sexual function of patients with endometriosis should be assessed by patient-reported outcome measures (PROMs) that present high reliability and validity. The objective was to study the PROMs used to assess sexual function for patients with endometriosis to improve their selection for research and clinical practice.

MATERIAL AND METHODS

We performed a systematic literature review from January 2000 to September 2023. All studies including women with confirmed endometriosis and assessing sexual quality of life or sexual function or sexual distress were retrieved. Different properties of PROMs used for sexual dysfunction were assessed according to the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) recommendations. Properties evaluated were: structural validity, internal consistency, cross-cultural validity, reliability, measurement error, criterion validity, construct validity, and responsiveness. This literature review was registered on Prospero as 2018 CRD42018102278.

RESULTS

Seventy-four articles with evaluation of sexual function were included. Of the 25 PROMs assessing sexual function, the Female Sexual Function Index (FSFI) was the most frequently used (34/74 [45.9%] items), followed by the Female Sexual Distress Scale (9/74 [12.2%] items) and the Sexual Activity Questionnaire (SAQ) (8/74 [10.8%] items). The most commonly used measurement properties were "hypothesis testing" and "responsiveness". The PROMs with a high level of evidence for these two measurement properties were the FSFI, the SAQ, the Short Sexual Functioning Scale, the Sexual Satisfaction Scale for Women, Sexual Quality of Life-Female, the Brief Profile of Female Sexual Function, and the Sexual Health Outcomes in Women Questionnaire. The FSFI questionnaire appeared to be more relevant for evaluating medical treatment, and the SAQ for evaluating surgical treatment. Only one instrument was specific to endometriosis (the Subjective Impact of Dyspareunia Inventory [SIDI]).

CONCLUSIONS

In this systematic literature review of sexual function assessment questionnaires in endometriosis, the FSFI and the SAQ questionnaires emerged as having the best measurement properties according to the COSMIN criteria. The FSFI questionnaire appears to be suited for evaluating medical treatment, and the SAQ for surgical treatment. The SIDI is the only specific questionnaire, but its responsiveness remains to be defined.

A comprehensive interventional program to improve the sexual function of women with endometriosis: a mixed-methods protocol study

BACKGROUND

Endometriosis is a chronic disease affecting 6-10% of women worldwide. Sexual dysfunction has been reported in a significant percentage of these patients. Thus, the present study will be conducted to design, implement, and determine the effectiveness of an interventional program to improve the sexual function of women with endometriosis.

MATERIALS AND METHODS

This mixed-methods study will be carried out in three phases with a sequential exploratory approach. In the first phase (qualitative study) participants will be selected by purposive sampling in Isfahan, Iran. The data will be collected through in-depth interviews and field notes and analyzed using conventional content analysis. The interventional program will be designed in the second phase based on the results of the qualitative study and literature review and using the Delphi method and panel of experts. The interventional program will be implemented at the individual level in the third phase to investigate its effect on improving women's sexual function. This phase includes quasi-experimental research, in which the pre- and post-intervention data will be collected from the intervention and control groups using the FSFI questionnaire and analyzed by descriptive and inferential statistical methods. Ultimately, a suitable interventional program will be presented by combining the data obtained in the qualitative and quantitative phases of the research.

CONCLUSION

Conducting the present study, along with the design and implementation of an appropriate, native, and culturally sensitive interventional program, can contribute to improving the sexual function of women with endometriosis and enhancing the quality of sexual relations between couples.

Acceptability, reliability, and validity of a vaginal insert for the self-assessment of endometriosis-associated deep dyspareunia: a cross-sectional study

BACKGROUND

Approximately half of people with endometriosis experience deep dyspareunia; however, there is no means of objective self-testing of endometriosis-associated deep dyspareunia.

AIM

The aim of this study was to assess the acceptability, test-retest reliability, and validity of a vaginal insert for a self-assessment of endometriosis-associated deep dyspareunia.

METHODS

Participants were recruited from a tertiary endometriosis center. Inclusion criteria were: 19 to 49 years of age, self-reported deep dyspareunia of ≥4 of 10, and surgically confirmed endometriosis. Participants completed 2 self-assessments using the vaginal insert to self-assess tenderness at the right and left pelvic floor, bladder, cervix-uterus, and posterior cul-de-sac (vaginal fornix). The participants recorded tenderness at each pelvic site and completed a questionnaire regarding the acceptability of the vaginal insert to assess deep dyspareunia. Test-retest reliability was assessed by correlating the tenderness scores between the 2 assessment dates. Over a 4-week period, the participants also recorded deep dyspareunia severity at each penetrative vaginal sex encounter. Validity was assessed by correlating vaginal insert tenderness to deep dyspareunia severity, and also to tenderness reported on a prior gynecologic pelvic examination.

OUTCOMES

The main outcome measures were the acceptability index score, tenderness (0-10) at each pelvic site, and prospective deep dyspareunia scores (0-10) over 4 weeks.

RESULTS

There were 19 participants (mean age 34 ± 7 years) who completed the study. The majority identified as female (94.7%), heterosexual (89.5%), and white (89.5%). The median acceptability index score was 0.72 (interquartile range, 0.66-0.81). For test-retest reliability, the intraclass correlation coefficients were 0.79 (P = .001) for the left pelvic floor, 0.82 (P < .001) for the right pelvic floor, 0.54 (P = .07) for the bladder, 0.89 (P < .001) for the cervix-uterus, and 0.77 (P = .003) for the cul-de-sac. The correlation between the highest self-assessed mean tenderness in each participant and self-reported deep dyspareunia over 4 weeks was r = 0.32, but correlations for each pelvic site varied significantly. Tenderness at each site on prior gynecologist pelvic exam was associated with higher self-assessed mean tenderness with the vaginal insert in each participant (effect sizes = 0.42-0.88).

CLINICAL IMPLICATIONS

The vaginal insert is acceptable and reliable for the objective self-assessment of endometriosis-associated deep dyspareunia, with initial evidence of validity.

STRENGTHS AND LIMITATIONS

A strength was the inclusion of participants who were avoiding sexual activity and a limitation was the small sample size.

CONCLUSION

Future studies with larger sample sizes are required to further establish the validity of the vaginal insert for the self-assessment of endometriosis-associated deep dyspareunia.

Sexual functioning and marital satisfaction among endometriosis patients in Malaysia: a cross-sectional study

Endometriosis affects the sexual functioning and marital satisfaction of couples in a complex manner due to its clinical presentation of the disease. This study aimed to evaluate the prevalence of sexual dysfunction and marital disharmony among women with endometriosis beyond their diagnosis and treatment. A cross-sectional online survey was conducted among women with endometriosis in an endometriosis society at a Malaysian university hospital. Sociodemographic and clinical data were collected. Sexual function was measured using the Malay Version Female Sexual Function Index (MVFSFI), while marital satisfaction was evaluated with the Malay Version Golombok Rust Inventory for Marital Satisfaction (MVGRIMS). A total of 166 patients participated in this survey. The median age was 35 years (Interquartile range, IQR:32.00-39.25 years); 91.6% of participants were Malay. The median score of MVFSFI was 56.00 (IQR: 34.75-68.00). Most of the study subjects (n = 96) reported poor to very severe marital satisfaction problems, equivalent to MVGRIMS transformed score of more than 5. High levels of MVGRIMS scores have a moderately strong negative correlation with lower scores for most domains of the MVFSFI. In the stepwise multiple logistic regression, only MVFSFI total scores (p = 0.029), MVFSFI lubrication scores (p = 0.009), and MVFSFI satisfaction (p = 0.010) scores were significantly associated with poor marital satisfaction. Both sexual dysfunction and marital satisfactions commonly affect women with endometriosis and are closely interlinked. Targeted efforts should be made in multiple aspects to improve the quality of sexual functioning and marital satisfaction among endometriosis patients.

Segmental Rectum Resection for Deep Endometriosis and Excision Similarly Improve Sexual Function and Pain

Segmental rectum resections for indications other than endometriosis were reported to result in up to 40% sexual dysfunctions. We, therefore, evaluated sexual function after low bowel resection (n = 33) for deep endometriosis in comparison with conservative excision (n = 23). Sexual function was evaluated with the FSFI-19 (Female Sexuality Functioning Index) and EHP 30 (Endometriosis Health Profile). The pain was evaluated with visual analogue scales. Linear excision and bowel resections improved FSFI, EHP 30, and postoperative pain comparably. By univariate analysis, a decreased sexual function was strongly associated with pain both before (p < 0.0001) and after surgery (p = 0.0012), age (p = 0.05), and duration of surgery (p = 0.023). By multivariate analysis (proc logistic), the FSFI after surgery was predicted only by FSFI before or EHP after surgery. No differences were found between low bowel segmental resection and a more conservative excision. In conclusion, improving pain after surgery can explain the improvement in sexual function. A deleterious effect of a bowel resection on sexual function was not observed for endometriosis. Sexual function in women with endometriosis can be evaluated using a simplified questionnaire such as FSFI-6.

Validation of the adapted female sexual function index among Chinese cisgender heterosexual women and sexual and gender minority women

BACKGROUND

The Female Sexual Function Index (FSFI) remains the most widely used scale for assessing female sexual function. However, while an adapted version of the FSFI has been proven to be suitable for Western sexual minority women, it has yet to be used in China.

AIM

This study aimed to validate the Mandarin Chinese version of the adapted FSFI among Chinese cisgender heterosexual women and sexual and gender minority women, and evaluate its psychometric properties.

METHODS

A cross-sectional online survey was conducted. The modified scoring method related to zero responses was examined, and structural validity, internal consistency, internal reliability, convergent validity, and known-group validity were evaluated.

OUTCOMES

The primary measure was the adapted FSFI, and the Positive Sexuality Scale and the New Sexual Satisfaction Scale-Short Form were used to test convergent validity.

RESULTS

A total of 431 Chinese adult women were recruited, including 193 cisgender heterosexual women and 238 sexual and gender minority women. Confirmatory factor analysis using the original scores supported the original 6-factor model. Using both Cronbach's α and McDonald's ω, the results showed that the values of the total scale and 6 subscales were in the 0.76 to 0.98 and 0.83 to 0.98 ranges, respectively, indicating satisfactory reliability. Moderate-to-strong correlations among the total FSFI scores and positive sexuality and sexual satisfaction were found (r = 0.32-0.71), supporting good convergent validity.

CLINICAL IMPLICATIONS

The adapted FSFI facilitates the use of more inclusive language in the clinical setting, allowing for a more comprehensive and unbiased assessment of sexual function in all women.

STRENGTHS AND LIMITATIONS

This study recruited both cisgender women of varied sexual orientations and gender minorities who were assigned female at birth, demonstrating that the adapted FSFI could be suitably applied to sexual minority populations. However, from a fully inclusive perspective of sex and gender, there is no research on how to accurately evaluate transgender women with female external genitalia or appropriately assess those with a female reproductive system but who do not self-identify as female. Therefore, more in-depth research is needed to further revise the FSFI for better use in the wider female population.

CONCLUSION

This Chinese version of the adapted FSFI has good psychometric properties and is a reliable and valid instrument to assess female sexual function. Furthermore, the modified scoring method could be an effective alternative among samples of sexually inactive women.

Impact of endometriosis on female sexual function: an updated systematic review and meta-analysis

Introduction

Endometriosis can lead to a state of chronic inflammation marked by the presence of scarring and adhesions within the pelvis and/or other parts of the body. Recent estimates suggest that globally this condition affects approximately 10% of women in the reproductive age group.

Aims

In this study we sought updated evidence on the association between endometriosis and sexual function in female patients.

Methods

We used standard assessment tools to conduct a systematic search of the PubMed, EMBASE, and Scopus databases for observational studies that documented the association of endometriosis with female sexual function. A random-effects model was used for the analysis, and effect sizes were reported as the weighted mean difference (WMD) or OR with 95% CIs.

Results

A total of 13 studies were selected for inclusion in our investigation. All of the included studies were cross-sectional in design. The data on sexual function in most of the studies were collected by using the Female Sexual Function Index (FSFI) tool, for which higher scores suggest better sexual function. The risk of sexual dysfunction (based on specific cutoffs for the FSFI score) was higher in women with than in women without endometriosis (OR 1.71; 95% CI, 1.21-2.43). In addition, when we used continuous scores to examine the risk of sexual dysfunction, diagnosis of endometriosis was associated with significantly lower overall FSFI scores (WMD, -3.40; 95% CI, -5.13 to -1.66) and lower scores on all of its 6 domains, ie, desire (WMD, -0.27; 95% CI, -0.53 to -0.02), arousal (WMD, -0.43; 95% CI, -0.79 to -0.07), lubrication (WMD, -0.49; 95% CI, -0.66 to -0.31), orgasm (WMD, -0.65; 95% CI, -1.07 to -0.23), satisfaction (WMD, -0.52; 95% CI, -0.77 to -0.26), and pain (WMD, -1.06; 95% CI, -1.57 to -0.55).

Conclusion

The findings of this study suggest that female patients with endometriosis have suboptimal sexual function compared with healthy female subjects. Patients with endometriosis should be offered sexual counseling and supportive care by a multidisciplinary team of gynecologists, psychologists, and sexual therapists.

Endometriosis Symptomatology, Dyspareunia, and Sexual Distress Are Related to Avoidance of Sex and Negative Impacts on the Sex Lives of Women with Endometriosis

BACKGROUND

Endometriosis affects approximately 10% of women and is associated with a range of symptoms including pelvic pain, abnormal bleeding, and painful sexual intercourse. However, very little is known about the relationship between endometriosis-related symptoms and sex.

METHODS

Women with a diagnosis of endometriosis (n = 2060; mean age = 30 years) completed a questionnaire measuring the frequency of endometriosis symptoms, dyspareunia, sexual distress, avoidance of sex, and the perceived negative impact of endometriosis symptoms on sex life.

RESULTS

In bivariate and multivariate logistic regression models with avoidance of sex and perceived negative impact of endometriosis symptoms on sex life as DVs, higher endometriosis symptom frequency, dyspareunia, and sexual distress were associated with greater avoidance of sex and higher perceived negative impact of endometriosis symptoms on sex life. With a two- and three-fold increase in the odds of avoiding sex and reporting a negative impact of endometriosis on sex lives, respectively, for each point increase in dyspareunia. Similarly, there was a 7% to 11% increase in avoidance of sex and the negative impact of endometriosis on sex lives, per one-point increase in symptom frequency and sexual distress.

CONCLUSIONS

The results highlight the considerable impacts of endometriosis symptomatology on women's sex lives and wellbeing. Better medical and counselling services may be needed to ameliorate the negative impact of endometriosis on women's sex lives.

Endometriosis decreases female sexual function and increases pain severity: a meta-analysis

PURPOSE

This study aimed to explore the effects of endometriosis on female sexual function.

METHODS

PubMed, Embase, and Web of Science databases were searched to analyze the Female Sexual Function Index (FSFI) or visual analog scale (VAS) scores between women with and without endometriosis. Data from publications were generated, and the sexual function of women with and without endometriosis was systematically evaluated.

RESULTS

A total of six publications were included in the study. The FSFI total score and its six domains were significantly lower in women with endometriosis: FSFI total score (P < 0.001), desire (P = 0.045), arousal (P = 0.039), pain domains (P < 0.001), lubrication (P < 0.001), orgasm (P = 0.001), and satisfaction (P < 0.001). Women with endometriosis exhibited more severity in terms of VAS scores for dyspareunia (P = 0.008) and chronic pelvic pain (P < 0.001); however, no significant severity for dysmenorrhea was observed (P = 0.118). Subgroup analysis showed that the region was not a source of heterogeneity. Publication bias was not noted in all included studies, and most results of the sensitivity analysis for the included indexes were stable, which implied that our results were relatively reliable.

CONCLUSION

The present meta-analysis provided evidence that endometriosis decreased female sexual function and increased the pain severity of dyspareunia and chronic pelvic pain.

Does laparoscopic treatment of deep endometriosis improve sexual dysfunction

Background

Endometriosis is one of the common gynecological problems during the reproductive years, affecting the quality of life, fertility, and sexual function of women. It is known that sexual dysfunction and quality of life are interrelated. Therefore, this study aimed to evaluate the effect of resection of endometriosis lesions via laparoscopic surgery on the improvement of sexual dysfunction in women with endometriosis.

Methods

This clinical trial was performed on 30 patients with endometriosis. The Female Sexual Function Index, Endometriosis Health Profile-30, and Visual Analog Scale were completed for the patients before laparoscopic surgery and three, six, and 12 months after surgery. The results were examined and compared before and after the intervention using the ANOVA test.

Results

The present results showed that the mean pain score of the patients (dysmenorrhea, dyspareunia, and pelvic pain) was significant after laparoscopic surgery (P<0.005). The female sexual function improved after laparoscopic surgery compared to the preoperative phase, and changes in the domains of psychological stimulation, humidity, and sexual orgasm were significant (P<0.005). Moreover, the female quality of life scores increased in all dimensions compared to the preoperative phase, although these improvements were not statistically significant.

Conclusion

The present results revealed that laparoscopic surgery is an effective treatment, leading to a considerable improvement in female sexual function.

New Understanding of Diagnosis, Treatment and Prevention of Endometriosis

For 100 years, pelvic endometriosis has been considered to originate from the implantation of endometrial cells following retrograde menstruation or metaplasia. Since some observations, such as the clonal aspect, the biochemical variability of lesions and endometriosis in women without endometrium, the genetic-epigenetic (G-E) theory describes that endometriosis only begins after a series of cumulative G-E cellular changes. This explains that the endometriotic may originate from any pluripotent cell apart from the endometrium, that 'endometrium-like cells' can harbour important G-E differences, and that the risk is higher in predisposed women with more inherited incidents. A consequence is a high risk after puberty which decreases progressively thereafter. Considering a 10-year delay between initiation and performing a laparoscopy, this was observed in the United Arab Emirates, Belgium, France and USA. The subsequent growth varies with the G-E changes and the environment but is self-limiting probably because of the immunologic reaction and fibrosis. That each lesion has a different set of G-E incidents explains the variability of pain and the response to hormonal treatment. New lesions may develop, but recurrences after surgical excision are rare. The fibrosis around endometriosis belongs to the body and does not need to be removed. This suggests conservative excision or minimal bowel without safety margins and superficial treatment of ovarian endometriosis. This G-E concept also suggests prevention by decreasing oxidative stress from retrograde menstruation or the peritoneal microbiome. This suggests the prevention of vaginal infections and changes in the gastrointestinal microbiota through food intake and exercise. In conclusion, a higher risk of initiating endometriosis during adolescence was observed in UAE, France, Belgium and USA. This new understanding and the limited growth opens perspectives for earlier diagnosis and better treatment.

The State of Health and the Quality of Life in Women Suffering from Endometriosis

Quality of life is related to good health, family relations, feeling of self-esteem, and ability to cope with difficult situations. Endometriosis is a chronic condition which affects different areas of life. The lack of satisfaction in everyday life is mainly due to constant pain. The process of adjusting to a life with illness is associated with negative emotions. The aim of the article is to review the current state of knowledge concerning the impact of social and medical factors on a population of women affected by endometriosis. Women with endometriosis have an impaired quality of life compared to the general female population. Psychological consequences of endometriosis include: depression, anxiety, powerlessness, guilt, self-directed violence, and deterioration of interpersonal relations. It may contribute to lower productivity at work and less satisfying intimate life. A multi-disciplinary, evidence-based care is needed. The disease can take away the ability to be physically active, obtain an education, work continuously, and interact with friends. Social support and cognitive-behavioral therapy are extremely important for healing.

A Study on the Correlation Between Quality of Life and Unhealthy Emotion Among Patients With Endometriosis

Objective

To investigate the influence of quality of life (QOL) on unhealthy emotions as well as relevant factors among patients with endometriosis for supporting relevant clinical care.

Methods

A convenience sampling method was used to administer questionnaires to 139 patients with endometriosis, using the Hamilton Anxiety Inventory (HAMA), the Depression Anxiety Scale (SDS), and the SF-12 Health Survey Short Form, and the results were analyzed. The SPSS20.0 software was used for statistical analysis on relevant data. If P < 0.05, there was statistical significance.

Results

Twelve-Item Short Form (SF-12) for health survey covered two comprehensive indexes, i.e., physical component summary (PCS) and mental component summary (MCS) scores. MCS score was the main factor influencing anxiety and depression in patients with endometriosis; the higher the MCS score, the lower the anxiety and depression degrees in patients with endometriosis (OR = 0.912, 95% CI: 0.877–0.949; OR = 0.899, 95% CI: 0.866–0.933). PCS score was a factor influencing anxiety degree; the higher the PCS score, the lower the anxiety degree (OR = 0.936, 95% CI: 0.891–0.983).

Conclusion

The QOL of patients with endometriosis is negatively correlated with anxiety and depression. Therefore, improvement in QOL may help relevant patients to relieve their unhealthy emotions.

Endometriosis-A Multifaceted Problem of a Modern Woman

Endometriosis is a chronic disease of unclear aetiology that affects millions of women around the world. It causes chronic pain, dysmenorrhea, and infertility, which significantly reduces the quality of daily life. The aim of the following study was a multivariate analysis of the functioning of women diagnosed with endometriosis, and the identification of the relationship between the level of physical activity and sexual functioning, ability to cope with stress, and the degree of anxiety and mood disorders. The prospective survey was conducted of 957 women. The research was carried out using standardised IPAQ, FSFI, HADS, and Mini-Cope questionnaires. The study showed that patients with endometriosis exhibit a higher level of depression and anxiety disorders (p = 0.01) and a lower level of sexual functions (p < 0.001). The influence of physical activity on the functioning of patients with endometriosis was demonstrated. Depending on the clinical stage of endometriosis, the influence of physical activity on individual aspects of life differed. Physical activity was shown, inter alia, to reduce anxiety (p = 0.015), and influence stress-coping strategies. Endometriosis affects the mental and physical health of women. Physical activity can reduce the severity of endometriosis symptoms and improve the daily functioning of patients.
