Erectile Dysfunction (ED)

(Impotence)

by Irvin H. Hirsch, MD

Every man occasionally has a problem achieving an erection, and such occurrences are considered normal. Erectile dysfunction (ED) occurs when a man is

  • Never able to achieve an erection

  • Achieves erection briefly but not long enough for intercourse

  • Achieves effective erection inconsistently

In the United States, about 50% of men aged 40 to 70 are affected somewhat, and the percentage increases with aging. However, ED is not considered a normal part of aging and can be successfully treated at any age.
