A Systematic Review on the Relationship Between Physical Activity and Sexual Function in Adults

Sexual function is a vital component of overall well-being and quality of life. Physical activity is known to have a profound influence on various aspects of health, but its impact on sexual function in the general population remains an under-explored area. This systematic review seeks to thoroughly examine existing evidence, aiming to establish the correlation between physical activity and sexual function in both male and female adults. We conducted a comprehensive search of electronic databases and relevant sources, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligible studies were those that investigated the effects of physical activity on sexual function using the International Index of Erectile Dysfunction (IIEF-5) questionnaire and the Female Sexual Function Index (FSFI). Quality assessment was performed on the included studies, and the findings were synthesized through qualitative analysis. The review identified 12 randomized controlled trials, primarily focusing on males, with interventions ranging from home-based walking to structured exercise training. Only two studies were conducted among females. The most recommended exercise was aerobic exercise. Consistent aerobic exercise proves to be a hopeful and efficient non-drug intervention for enhancing erectile function in men. However, when considering the effects of physical exercise programs on sexual function and the quality of sexual life of females, the results present challenges in drawing clear conclusions. Health policymakers play an important role in providing guidelines and recommendations to healthcare professionals, encouraging them to prescribe exercise as a preferable alternative to pharmacological treatments for enhancing sexual functions in both men and women.
