The association between cardiorespiratory endurance and erectile dysfunction severity in older men

Background Erectile dysfunction (ED) is prevalent among older men and negatively associated with lower physical fitness and cardiovascular health. While previous studies often rely on self-reported activity levels, this study uses objective measures of cardiorespiratory endurance (CRE), specifically peak oxygen uptake (VO₂peak), to investigate its relationship with ED severity. Objective To assess the association between objectively measured CRE (VO₂peak) and ED severity in healthy men aged 55 – 75 years and evaluate the influence of age, BMI, and depressive symptoms as potential confounders. Methods This cross-…
