This study explored the relationships between the decline in sexual function and psychological burdens and life satisfaction in older men with the aim of providing prospective targets for interventions. From January 2016 to January 2019, we selected 1,326 men aged over 50 years old. We adopted the International Index of Erectile Function-5 (IIEF-5), self-estimated intravaginal ejaculatory latency time (IELT), the premature ejaculation diagnostic tool (PEDT), the General Anxiety Disorder-7 (GAD-7), the Patients Health Questionnaire-9 (PHQ-9), the satisfaction with life scale and the control, autonomy, self-realisation and pleasure scale (CASP-19) to measure premature ejaculation, erectile dysfunction and well-being (including, depression, anxiety, and life quality and satisfaction) respectively. The individuals were divided into two main groups: the decline group and the no-decline group. The incidences of erectile dysfunction (ED), premature ejaculation (PE), anxiety and depression in men who reported a decline in sexuality were 73.83% (330/447), 63.98% (286/447), 75.84% (339/447) and 68.46% (306/447) respectively. Men who showed a decline in sexuality had significantly worse psychological and life satisfaction/quality scores than those in the no-decline group (p < .001 for all). When they had PE or ED simultaneously, these differences widened. Significantly worsened psychological status and life quality/satisfaction scores could be observed in patients who had declined sexual desire and declined frequency of sex (p < .001 for both). Under the impact of the decline in sexual function, the younger participants (age < 60) had significantly worsened negative emotions and life quality and satisfaction. Based on the results of the study, we found that the decline in sexuality was associated with depression and anxiety and worse life satisfaction and quality. Clinicians need to pay more attention to psychological status and life satisfaction and quality for those patients affected by a decline in sexuality.
