The prevalence of erectile dysfunction (ED) in adult men varies with age, health status and regional differences, but epidemiological data worldwide can provide a reference. The following is a comprehensive analysis based on multiple studies:
I. Overall prevalence
◦1. General population: About 5%~20% of adult men have varying degrees of ED (from mild to severe).
◦2. Age stratification:
■ Under 40 years old: 5%~10%
■ 40~60 years old: 15%~35%
■ Over 60 years old: 40%~70%
II. Prevalence of high-risk groups
Chronic disease patients:
Diabetes: About 50%~75% of male diabetic patients have ED (10~15 years earlier than their peers).
Hypertension: About 40%~45% (related to vascular damage and drug side effects).
Cardiovascular disease: About 60%~65% of patients with coronary heart disease have ED (ED may be an early signal of cardiovascular events).
Psychologically related ED:
Depression patients: ED risk increases by 50%~70%, and antidepressants (such as SSRIs) may aggravate symptoms.
Long-term stress/anxiety: About 20%~30% of ED cases are mainly caused by psychological factors.
III. The relationship between age and ED
Under 30 years old: mostly psychological or lifestyle related (such as smoking, alcoholism), the prevalence is about 1%~5%.
40~50 years old: organic factors (such as vascular lesions) begin to appear, and the prevalence rises to 15%~25%.
Over 70 years old: due to aging and accumulation of chronic diseases, the prevalence reaches 50%~80%, but some elderly people still maintain normal functions
