An erection happens when blood rushes to the penis. But when arteries are clogged by atherosclerosis, the reduced blood flow results in impotence.
There are physical and psychologist issues that attribute to erectile dysfunction. In many cases erectile is caused by physical issues:

- Enlarged prostate
- Metabolic syndrome — a condition involving increased blood pressure, high insulin levels, body fat around the waist and high cholesterol
- Parkinson’s disease
- Multiple sclerosis
- Certain prescription medications
- Tobacco use
- Peyronie’s disease — development of scar tissue inside the penis
- Alcoholism and other forms of substance abuse
- Sleep disorders
- Treatments for prostate cancer or enlarged prostate
- Surgeries or injuries that affect the pelvic area or spinal cord
