Sexual Dysfunction in Patients with Chronic Non-Genital Physical Disease: An Umbrella Review

Many primary studies and reviews have been published on the influence of chronic diseases (CDs) on sexual dysfunction (SD), but CDs not involving the genitals are less well represented in the literature. Aim: To determine the prevalence of SD in patients with non-genital CD and assess the overall impact on sexual functioning. Methods: An umbrella review was performed of published systematic reviews on the relationship between the occurrence of CDs not involving the genitals and patients’ sexual functioning, following the PRISMA guidelines. PubMed, EMBASE, the Cochrane Library, PsycInfo, Scopus, and CINAHL were used to find publications for inclusion in the review, with two independent researchers performing the search and selection of articles, data extraction, and quality assessment. The relative risk (RR) or odds ratio (OR) with 95% confidence was used as an indicator of the association between CD and SD across studies. The quality of studies included in the review was assessed using Amstar-2. Outcomes: Forty-three systematic reviews, thirty of which included a meta-analysis, met the inclusion criteria, representing a total of 880,586 patients (756,629 (85.9%) men, 68,388 (7.8%) women, and 55,569 (6.3%) unspecified). Results: Among men, CD is associated with erectile dysfunction, and among females, with lower levels of desire, arousal, lubrication, orgasm, and sexual satisfaction and with increased pain during intercourse. For both men and women, depression, anxiety, and fatigue are also reported, while women with CD are more affected by a poor body image than men. Clinical implications: Patients with CD, especially females, should be more routinely assessed for the impact of their condition on sexual functioning. The impact of CD on men’s sexuality has been extensively studied in terms of erectile capacity, but other aspects of their sexuality are largely neglected. Strengths and limitations: This is the first umbrella review to bring together the documented findings regarding sexual dysfunction among patients with various non-genital CDs. While the heterogeneity of the CDs makes the study unique and clinically relevant, it renders the interpretation of the results more difficult. The overrepresentation of men in existing studies reflects the current state of research but limits the applicability of the findings for women. Conclusion: Women and men with non-genital CDs can suffer from SD or reduced sexual function. Health professionals should pay more attention to managing these sexual disorders, even when the disease does not affect the genitals.
