What Age Do Most Men Start Having Erectile Dysfunction?
Medically reviewed by Andre Stone | MD, University of Pittsburgh School of Medicine on August 25th, 2026.
Erectile dysfunction can begin at any age, but it becomes more common as men get older, particularly after age 40. Studies show that approximately 40% of men at age 40 have some degree of ED, rising to 70% by age 70. The condition becomes more common partly because aging is associated with blood-vessel changes and health conditions such as diabetes and cardiovascular disease. Low testosterone can contribute in some men but is not the usual sole cause of ED. However, ED can occur at any age. In younger men, stress and psychological factors may contribute, but physical conditions, medications, substance use, and other causes should also be considered. Symptoms may include repeated difficulty getting or maintaining an erection firm enough for sexual activity. Occasional difficulty is common and does not necessarily mean a person has ED.
