What causes erectile dysfunction?

The causes of erectile dysfunction are classified into physical and psychological.
Psychological causes of erectile dysfunction:
• Being nervous, especially about sexual performance
• Guilt (when you feel guilty about that intercourse, for various reasons)
• Gayness
• Relationship problems
• Depression or grief
• Exhaustion and overworking.
If a man still has morning erections or can develop a firm erection by masturbating, the problem is most likely psychological.
Common physical causes of erectile dysfunction:
• deterioration of the blood vessels (most common for older men)
• excessive drinking and smoking
• obesity and being out-of-shape
• diabetes
• taking blood pressure and depression medications
• taking recreational drugs, like cocaine.
Rare physical causes:
• nervous diseases
• damaged spinal cord or brain
• complications of abdomen surgeries, particularly prostate operations
• hormone problems (very rare)
• excessive outflow of blood from the vessels of the penis
Lack of hormones, often diagnosed in expensive clinics as the major ED cause, is in fact a very rare cause of ED. However, lack of hormones can be caused by testicle damage or injury to the base of the brain.
Think well if you really need the costly treatment they offer! In the overwhelming majority of cases changing lifestyle, physiological help of your partner and exercises combined with reliable ED medications that help support normal love life is the best way to resolving the problem.
