There is limited information on the specific psychosocial risks at work that can impact sexual function. The general aim of this study was to investigate the effects of multiple dimensions of psychosocial work stressors on the male sexual function. This was a cross-sectional study conducted among 153 male nurses working in two hospitals in Iran. Sexual function and psychosocial job stressors were measured using the Persian version of the International Index of Erectile Function (P-IIEF) and the Persian version of the Health and Safety Executive (P-HSE) Management Standards Indicator Tool. The Persian version of the Work Ability Index (P-WAI) was used to assess the mediating effect of work ability on the relationship between overall stress and subscales of sexual function. The data were analyzed using Pearson product-moment correlation, one-way analysis of variance (ANOVA), and multiple linear regressions. The subscales of psychosocial job stressors, especially the subscale of role, had a significant correlation with several domains of sexual function. The regression modeling indicated that the subscales of role and job demands were significant predictors of various domains of sexual function. The effect of overall stress on intercourse satisfaction was fully mediated by WAI. In the other indicators of sexual function, overall stress score had only a significant direct effect, not mediated by WAI. Intervention programs to improve sexual function should focus on increasing nurses' involvement in making decisions related to jobs and on using ergonomic principles related to balancing job demands and the level of nurses' capabilities.
