Male sexual function is regulated by vascular function and impaired vascular function is closely related with erectile dysfunction (ED). Vascular functions are positively influenced by physical fitness (i.e., aerobic capacity, muscle strength, and flexibility). The detailed associations between physical fitness and male sexual function remain poorly understood. The present study aimed to clarify the influence of physical fitness on male sexual function.
In 177 adult men, peak oxygen consumption (VO2 peak), handgrip strength (HGS), and sit and reach were measured as indices of physical fitness. Arterial stiffness and erectile function were assessed by carotid–femoral pulse wave velocity (cfPWV) and the International Index of Erectile Function 5 (IIEF5) questionnaire, respectively. IIEF5 score was significantly correlated with VO2 peak (rs = 0.52), HGS (rs = 0.37), and cfPWV (rs = −0.44); and multivariate linear regression analyses showed that VO2 peak, HGS, and cfPWV were significantly associated with IIEF5 score after considering confounders.
The receiver operator characteristic curve analysis suggested that the cutoff values for predicting ED were 29.0 ml/min/kg for VO2 peak and 39.3 kg for HGS. The IIEF5 score was the highest in the subjects with the values of both VO2 peak and HGS were higher than their respective cutoff values, while the IIEF5 score was the lowest in the subjects with the values of both VO2 peak and HGS were lower than their respective cutoff values. These results suggest that the maintenance of high aerobic capacity and muscular strength may offset deterioration of male sexual function.
Erectile dysfunction (ED), defined as the inability to attain or maintain penile erection that is sufficient for satisfactory sexual performance (Yafi et al., 2016), is a common clinical problem worldwide. The Massachusetts Male Aging Study identified that the prevalence of mild-to-moderate ED is 52% in men aged 40–70 years (Feldman, Goldstein, Hatzichristou, Krane, & McKinlay, 1994), which suggests that ED is widely prevalent among middle-aged and elderly men.
ED has been previously reported to be associated with depressive symptoms (Nelson, Mulhall, & Roth, 2011) and has been observed to affect the quality of life (QOL) negatively (Yafi et al., 2016). In addition, a previous meta-analysis has revealed that men with ED exhibited 48% higher risk of cardiovascular disease (CVD) than men without ED (Dong, Zhang, & Qin, 2011). The assessment of male sexual function and prevention of age-related deterioration of male sexual function are necessary for better QOL and for preventing occurrence of CVD in future.
