Erectile Dysfunction

Erectile dysfunction, or ED, is when it is hard to get or keep an erection that's firm enough for sex. ED affects as many as 30 million men. Most men have problems with erections from time to time. But when this happens more than half of the time, then ED is present. ED can happen when health problems limit blood flow or damage nerves in the penis. ED can also be caused by stress or emotional reasons.
