Qualitative and quantitative aspects of sex life in the context of endometriosis: a multicentre case control study.

RESEARCH QUESTION: What are the specific characteristics of sexual activity in women with endometriosis compared with women without endometriosis? DESIGN: Multicentre case control study. Participants were recruited from university hospitals, district hospitals and doctor's offices in Germany, Switzerland and Austria. A total of 565 women with endometriosis were pair-matched to 565 control women by age and ethnic background. Diagnosis of endometriosis was confirmed by histology, and disease stage was classified according to American Society for Reproductive Medicine criteria. Data on sexuality were collected using selected questions from the Brief Index of Sexual Function and the Sexual History Form. RESULTS: Altogether, 69.1% of women with endometriosis and 77.8% of control women engaged in sexual activity during the month before the study period (P < 0.001). Overall, 42.3% of endometriosis-affected women and 30.5% of the control women desired a higher frequency of sexual activity (P < 0.001). Petting, foreplay and vaginal sexual intercourse were reported to be practised less often by women with endometriosis. Frequencies for masturbation, reciprocal masturbation, oral and anal sex were similar in both groups. Dyspareunia was negatively associated with sexual activity (OR 2.42, 95% CI 1.26 to 4.63), whereas chronic pain showed no association with sexual activity (OR 1.35, 95% CI 0.93, 1.96). CONCLUSIONS: Women with endometriosis have lower frequencies of petting, foreplay and vaginal sexual intercourse than control women; this difference has to be attributed, at least in part, to dyspareunia. Potentially pain-free sexual options are used to a limited degree. As endometriosis-affected women desire higher levels of sexual activity, sexual counselling should be included in medical support.

Fatigue - a symptom in endometriosis.

STUDY QUESTION: Is fatigue a frequent symptom of endometriosis? SUMMARY ANSWER: Fatigue is an underestimated symptom of endometriosis as it affects the majority of women with endometriosis, but it is not widely discussed in literature. WHAT IS KNOWN ALREADY: Fatigue can be a symptom of endometriosis causing major distress impacting the daily activities and quality of life of women with endometriosis. However, few studies with large sample sizes have investigated fatigue as a symptom of endometriosis. STUDY DESIGN, SIZE, DURATION: The study was designed as a multi-center matched case-control study. Recruitment took place at hospitals and private practices in Switzerland, Germany and Austria between 2010 and 2016. Data was collected from 1120 women, 560 of them with endometriosis. The women with endometriosis were matched to 560 control women in regard to age ±3 years and ethnic background. PARTICIPANTS/MATERIALS, SETTING, METHODS: Diagnosis of women with endometriosis had to be surgically and histologically confirmed. Surgical exclusion or absence of any endometriosis-identifying symptoms was required for control subjects. Materials included surgical and histological reports as well as data retrieved from a self-administered questionnaire. This study focused on the symptom fatigue in endometriosis. Relationships of variables were established by regression analysis and associations were quantified as odds ratios. MAIN RESULTS AND THE ROLE OF CHANCE: Frequent fatigue was experienced by a majority of women diagnosed with endometriosis (50.7% versus 22.4% in control women, P < 0.001). Fatigue in endometriosis was associated with insomnia (OR: 7.31, CI: 4.62-11.56, P < 0.001), depression (OR: 4.45, CI: 2.76-7.19, P < 0.001), pain (OR: 2.22, CI: 1.52-3.23, P < 0.001), and occupational stress (OR: 1.45, CI: 1.02-2.07, P = 0.037), but was independent of age, time since first diagnosis and stage of the disease. LIMITATIONS, REASONS FOR CAUTION: Women with asymptomatic endometriosis cannot be excluded in the control group which would lead to underestimation of our results. The study's design allows no evaluation of causal effects. WIDER IMPLICATIONS OF THE FINDINGS: As fatigue is experienced by numerous women with endometriosis, it needs to be addressed in the discussion of management and treatment of the disease. In addition to treating endometriosis, it would be beneficial to reduce insomnia, depression, pain and occupational stress in order to better manage fatigue. STUDY FUNDING/COMPETING INTEREST(S): There was no additional funding received for this study and no conflict of interest. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, NCT02511626.

Does Endometriosis Affect Sexual Activity and Satisfaction of the Man Partner? A Comparison of Partners From Women Diagnosed With Endometriosis and Controls.

BACKGROUND: Endometriosis-associated pain and dyspareunia influence female sexuality, but little is known about men's experiences in affected couples. AIM: To investigate how men partners experience sexuality in partnership with women with endometriosis. METHODS: A multi-center case-control study was performed between 2010 and 2015 in Switzerland, Germany, and Austria. 236 Partners of endometriosis patients and 236 partners of age-matched control women without endometriosis with a similar ethnic background were asked to answer selected, relevant questions of the Brief Index of Sexual Functioning and the Global Sexual Functioning questionnaire, as well as some investigator-derived questions. OUTCOMES: We sought to evaluate sexual satisfaction of men partners of endometriosis patients, investigate differences in sexual activities between men partners of women with and without endometriosis, and identify options to improve partnership sexuality in couples affected by endometriosis. RESULTS: Many partners of endometriosis patients reported changes in sexuality (75%). A majority of both groups was (very) satisfied with their sexual relationship (73.8% vs 58.1%, P = .002). Nevertheless, more partners of women diagnosed with endometriosis were not satisfied (P = .002) and their sexual problems more strongly interfered with relationship happiness (P = .001) than in partners of control women. Frequencies of sexual intercourse (P < .001) and all other partnered sexual activities (oral sex, petting) were significantly higher in the control group. The wish for an increased frequency of sexual activity (P = .387) and sexual desire (P = .919) did not differ statistically between both groups. CLINICAL TRANSLATION: There is a need to evaluate qualitative factors that influence sexual satisfaction in endometriosis patients. CONCLUSIONS: This is one of the first studies to investigate male sexuality affected by endometriosis. The meticulous verification of diagnosis and disease stage according to operation reports and histology allows for a high reliability of diagnosis. Our men's response rate of almost 50% is higher compared to other studies. Recruiting men through their woman partner may have caused selection bias. The adjustment to the specific situation in endometriosis by selecting questions from the Brief Index of Sexual Functioning and Global Sexual Functioning and adding investigator-derived questions likely influenced the validity of the questionnaires. Despite the fact that both partners of endometriosis patients and of control women largely reported high sexual satisfaction, there are challenges for some couples that arise in the context of a sexual relationship when one partner has endometriosis. Challenges such as sexuality-related pain or a reduced frequency of sexual activities should be addressed by health care professionals to ameliorate any current difficulties and to prevent the development or aggravation of sexual dysfunction.

Comparison of male and female perspective in couples involved in sexual relationships and facing endometriosis.

Background: While the sexuality of patients with endometriosis is an established topic in research, the possible effect of endometriosis on partnership sexuality has come to the fore only recently. To improve counseling, more information is needed on how both partners experience sexuality in the context of endometriosis. Aim: Previous research regarding endometriosis and sexuality normally focused on one partner to explore couples' intimate relations, whereas this study provides a comparison on both partners' perspectives on their common sexuality. Methods: An overall 302 couples received a questionnaire based on the Brief Index of Sexual Functioning and Sexual History Form, which was modified by endometriosis specialists to better focus on endometriosis-specific aspects. To detect different perspectives on common sexuality within the couple, the Wilcoxon test and the Pearson chi-square test were performed. Outcomes: Various aspects of couple sexuality were assessed by both partners to investigate divergent perspectives between the man and the woman within a couple. Results: On one hand, male and female partners seem to have divergent perspectives on sexual satisfaction in general, desired frequency of sexual contacts, and the question of the female partner engaging in sexual activity despite discomfort. On the other, they have similar perspectives on who takes initiative in sexual contacts, satisfaction with variety in the sexual relationship, and the impact of sexual limitations on their satisfaction within the partnership. Clinical implications: Endometriosis research addressing issues related to sexuality should include male partners; the same applies to consulting women with endometriosis in the context of their relationships rather than as individuals. Strengths and Limitations: This is the first analysis conducted on a larger scale of data from both partners in couples dealing with endometriosis. As it provides quantitative information only, some qualitative information remains unexplored. Conclusion: As both partners showed tendencies to overestimate their partners' sexual satisfaction and had different perspectives on sensitive topics in sexuality, such as the female partner engaging in sexual activity despite discomfort, addressing sexual communication could be a starting point in counseling couples dealing with endometriosis.

Dysmenorrhea in adolescents requires careful investigation of endometriosis-an analysis of early menstrual experiences in a large case-control study.

Introduction: Recent evidence shows that endometriosis, a significant cause of infertility, may already present in adolescents. Dysmenorrhea, often leading to school absences, is a key symptom of the maturing menstrual cycle but also of endometriosis. However, it is often perceived as "normal" and left untreated. In adolescents, laparoscopy, the standard procedure to diagnose endometriosis, is performed particularly cautiously. To improve reproductive health in adolescents, we evaluate associations between early menstrual experiences and endometriosis. Methods: Retrospective data on early menstrual experiences from 563 women with surgically/histologically verified endometriosis and from 563 age-matched controls were compared. Study participants were recruited in Switzerland, Germany, and Austria. Information on menstrual experiences was collected via a structured questionnaire. Results: The bivariate analysis showed that early menarche (p = 0.004), dysmenorrhea and negative memories of menarche (p < 0.001) were significantly associated with a diagnosis of endometriosis. After controlling for confounders in bivariate regression analysis occurrence of dysmenorrhea (p = <0.001, OR 5,74, 95% CI 3.82-7.22) especially with onset >3 years after menarche ((p = <0.001, OR 3.42, 95% CI 2.09-5.64) remained statistically significant predictors for diagnosis of endometriosis. Dysmenorrhea in mothers and mothers' perceived attitude towards menstruation were not associated with the occurrence of Endometriosis. Conclusions: Dysmenorrhea and onset of dysmenorrhea at menarche or several years after it are strongly associated with the development of endometriosis. As mothers perceived attitudes towards menstruation show no significant association with their daughters' experiences, physical symptoms accompanying menarche and menstrual period pain in adolescents seem to be very reliable predictors in diagnosis of endometriosis. Therefore, dysmenorrhea in adolescents requires careful investigation of possible endometriosis, especially if it does not respond to medical management. Clinical trials registration: The study was registered on ClinicalTrials.gov, identifier (NCT02511626).

Physical Activity in Women with Endometriosis: Less or More Compared with a Healthy Control?

BACKGROUND: Endometriosis, i.e., endometrial-like tissue outside the uterus, is a chronic inflammatory condition affecting physical functioning. However, the specific levels of physical activity (PA) in the context of endometriosis and different disease symptoms remain unclear. METHODS: This multi-center, cross-sectional study compared PA levels and influencing factors in endometriosis patients and non-endometriosis patients. Data were collected through questionnaires. Endometriosis was surgically confirmed. A statistical analysis was performed with appropriate tests. RESULTS: The study included 460 women with endometriosis and 460 age-matched women without this condition. The two groups did not differ significantly in terms of age, education level, or stable partnership. Women with endometriosis exhibited lower PA levels, practicing fewer hours of sports weekly and climbing fewer stairs daily compared to the control group. These differences remained significant after controlling for confounding factors. Factors such as endometriosis, current dysmenorrhea, and depression were associated with decreased PA. CONCLUSIONS: These findings suggest that women with endometriosis engage in less PA compared to those without this condition. These results highlight the need for interventions to promote increased PA in endometriosis patients and harness the associated health benefits. Further research is warranted to explore the underlying mechanisms and develop tailored exercise therapies for this population.

Living with endometriosis: Comorbid pain disorders, characteristics of pain and relevance for daily life.

BACKGROUND: Pain plays a central role in endometriosis. The complex relationship among pain characteristics, comorbid pain disorders and daily life represents a challenge for medical support. This multicentre cross-sectional case-control study analysed the association between endometriosis-related chronic pain and functions of daily life in 510 women with endometriosis, 265 (52%) who experienced chronic pain, either from endometriosis alone (N = 134, 26.3%) or in association with additional pain disorders (N = 131, 25.7%). METHODS: Self-administered questionnaires from the Brief Pain Inventory and the Pain Disability Index were used to investigate associations between pain characteristics (frequency, duration, intensity) and daily life. Also, associations between different endometriosis characteristics (rASRM stage, presence of adhesions, localisation of lesions) and pain were evaluated. RESULTS: Chronic pain is negatively associated with almost all (12/14) aspects of daily life investigated, including standing, walking, sitting, defaecation, sleep, sports activities, family and domestic responsibilities, sexuality, social functioning, professional life, mood, and joy of life. Altogether, 33.7% of women with chronic pain reported moderate and 27.5% severe limitations. Comorbid pain disorders resulted in significantly more limitations. The length of pain episodes showed a particularly important influence, especially for family/domestic responsibilities (OR 22.94, p < 0.001), professional life (OR 16.56, p < 0.001) and social functioning (OR 41.03, p < 0.001). CONCLUSIONS: Our data confirm that despite treatment, about 50% of women experience pain. Pain was associated with at least moderate negative effects on almost all areas of daily life; additional pain comorbidities increased limitations. Improving pain management is essential for improving quality of life in women with endometriosis. SIGNIFICANCE: The study provides an accurate overview of the impact of endometriosis-associated pain on daily life. This is important because pain plays a central role in women living with endometriosis, and despite modern therapies, many women continue to suffer from chronic pain. The detailed analysis of its impact with a comprehensive survey of all aspects of daily life in a very large study population is unique. We expect an improved understanding of consequences of pain to significantly advance medical support in these patients.

Does endometriosis affect professional life? A matched case-control study in Switzerland, Germany and Austria.

OBJECTIVES: Endometriosis is a gynaecological disease most commonly causing severe and chronic pelvic pain as well as an impaired quality of life. The aim of this study was to investigate if and how endometriosis affects choices regarding professional life as well as the quality of daily working life. DESIGN, SETTING AND PARTICIPANTS: In the context of a multicentre case-control study, we collected data from 505 women with surgically/histologically confirmed diagnosis of endometriosis and 505 matched controls. Study participants were recruited prospectively in hospitals and doctors' practices in Switzerland, Germany and Austria. Using a detailed questionnaire, the study investigated work-life and career choices of study participants. MAIN OUTCOME MEASURES: Associations between endometriosis/disease symptoms and limitations in career development as well as ability to work. RESULTS: Women with endometriosis were less often able to work in their desired profession than women from the control group (adjusted OR=1.84, 95% CI: 1.15 to 2.94, R2=0.029, p=0.001) and they had to take health-related limitations into consideration in their career decisions to a significantly higher degree than women in the control group (OR=4.79, 95% CI: 2.30 to 9.96, R2=0.063, p<0.001). Among women with endometriosis, chronic pain was significantly associated with increased sick leave (OR=3.52, 95% CI: 2.02 to 6.13, R2=0.072, p<0.001) as well as with loss of productivity at work (OR=3.08, 95% CI: 2.11 to 4.50, R2=0.087, p<0.001). CONCLUSIONS: Endometriosis is associated with impairment of professional life, in particular with regard to career choices. Further research to develop strategies to support endometriosis-affected women in realising professional opportunities is recommended. TRIAL REGISTRATION NUMBER: NCT02511626; Pre-results.

Endometriosis, especially mild disease: a risk factor for miscarriages.

OBJECTIVE: To investigate the prevalence of miscarriage in women with endometriosis (WwE) compared with disease-free control women (CW). DESIGN: Cross-sectional analysis nested in a retrospective observational study (n = 940). SETTING: Hospitals and associated private practices. PATIENT(S): Previously pregnant women (n = 268) within reproductive age in matched pairs. INTERVENTION(S): Retrospective analysis of surgical reports and self-administered questionnaires. MAIN OUTCOME MEASURE(S): Rate of miscarriage, subanalysis for fertility status (≤12 vs. >12 months' time to conception), endometriosis stages (revised American Society of Reproductive Medicine classification [rASRM] I/II vs. III/IV) and phenotypic localizations (superficial peritoneal, ovarian, and deep infiltrating endometriosis). RESULT(S): The miscarriage rate was higher in WwE (35.8% [95% confidence interval 29.6%-42.0%]) compared with CW (22.0% [16.7%-27.0%]); adjusted incidence risk ratio of 1.97 (95% CI 1.41-2.75). This remained significant in subfertile WwE (50.0% [40.7%-59.4%]) vs. CW (25.8% [8.5%-41.2%]) but not in fertile WwE (24.5% [16.3%-31.6%]) vs. CW (21.5% [15.9%-26.8%]). The miscarriage rate was higher in women with milder forms (rASRM I/II 42.1% [32.6%-51.4%] vs. rASRM III/IV 30.8% [22.6%-38.7%], compared with 22.0% [16.7%-27.0%] in CW), and in women with superficial peritoneal endometriosis (42.0% [32.0%-53.9%]) compared with ovarian endometriosis (28.6% [17.7%-38.7%]) and deep infiltrating endometriosis (33.9% [21.2%-46.0%]) compared with CW (22.0% [16.7%-27.0%]). CONCLUSION(S): Mild endometriosis, as in superficial lesions, is related to a great extent of inflammatory disorder, possibly leading to defective folliculogenesis, fertilization, and/or implantation, presenting as increased risk of miscarriage.

The effect of extended culture of cumulus-oocyte complexes in follicular fluid during in vitro fertilisation cycles.

PURPOSE: To assess the clinical and biological effect of the preincubation of oocytes in follicular fluid prior to IVF and ICSI cycles. METHODS: A series of patients were treated by the preincubation of oocytes in the patients' follicular fluid for 3 h after oocyte retrieval followed by processing with standard protocols. Control oocytes were preincubated in normal IVF culture medium. Fluorescence techniques were used to examine oocyte mitochondrial membrane potential. RESULTS: Fertilisation, pregnancy, and implantation rates were all significantly improved after the preincubation of oocytes in follicular fluid. Further tests suggested that differences in pH between follicular fluid and artificial culture medium may be critical to these differences. CONCLUSIONS: Preincubation of human oocytes in follicular fluid improves the results after IVF. This may be partly due to the use of a non-"physiological" pH in artificial culture media during in vitro fertilisation procedures.
