Chronic ED affects about 5% of men in their 40s and 1525% of men by the age of 65. Transient ED and inadequate erection affect as many as 50% of men between the ages of 40 and 70. In around 95% of the cases, a satisfactory treatment can be found. Erectile dysfunction is treatable at any age, and awareness of this fact has been growing. More men have been seeking help and returning to normal sexual activity because of improved, successful treatments for erectile dysfunction.
