It’s quite common. The American Diabetes Association estimates that between 35% and 50% of diabetic men have erectile dysfunction (ED).
The National Institute of Diabetes and Digestive and Kidney Diseases (part of the U.S. National Institutes of Health) reports that diabetic men are two to three times more likely to have ED than men who are not diabetic. Men with diabetes may also develop ED 10 to 15 years earlier.
Erectile dysfunction is considered a complication of diabetes. It is also thought to be a marker for diabetes, especially in men age 45 and under.
