Having episodes of impotence is typically not concerning. Feeling stressed, tired, or ingesting too much alcohol, it may be difficult to get an erection. Most men can achieve performance most of time that they are aroused, and episodes of impotence are temporary. When impotence is ongoing it may cause stress, relationship problems or affect self-confidence. Erectile dysfunction can occur at any age; however, it is more common with an increase age. Approximately fifty percent of men age forty to seventy have ED. Seventy percent of men aged seventy and above have ED.
The brain, hormones, psychological response, nerves, muscles and blood vessels create the complex system that stimulates male sexual arousal. Physical symptoms related to a medical diagnosis are the most common reasons for erectile dysfunction. Heart disease, clogged blood vessels (atherosclerosis), high blood pressure, metabolic and endocrine syndromes such as diabetes, and being overweight are the most common conditions associated with impotence. These common conditions are typically a result of; reduced blood flow to penis, diseases which affect the nerves going to the penis (for ex, multiple sclerosis, a stroke, and diabetes), hormonal causes such as low testosterone, trauma or injury to the nerves of the penis and/or side effects to certain medications such as antidepressants, heart and stomach medications.
