Men with erectile dysfunction, or ED, have difficulties having or sustaining an erection firm enough for sexual intercourse. It's a general form of sexual dysfunction in men. It's getting more popular as men grow older, but it's not considered part of their aging. Given the personal nature of the disorder, it is not rare for patients – anxious for a return to normalcy – to fall victim to so-called ED specialists who promise a lot and offer nothing. It's clear to see how this is going to happen.
