Erectile dysfunction (ED) is typically used to describe the repeated inability to attain and maintain an erection for sexual intercourse.
This condition is also commonly known as impotence. Impotence, however, may refer to other problems that interfere with sexual intercourse. These include a lack of sexual desire and problems with ejaculation or orgasm. Using the term erectile dysfunction makes it clear that those other problems are not involved.
It is normal for men to experience changes in erectile function, such as taking longer to achieve an erection. When the problem becomes persistent, it can be a sign of a physical or emotional problem. ED can be a total inability to achieve erection, an inconsistent ability to do so, or a tendency to sustain only brief erections.Learn more about the symptoms of erectile dysfunction ›

It can also be a result of a more serious medical problem, such as arteriosclerosis, cardiovascular disease, or diabetes.
These are some other causes of impotence:

I remember the first time my dad talked to me about erectile dysfunction. He said … um, well, he … of course, I’m kidding! My father was born in the 1930s. Men of his generation might have walked 16 miles through an ice storm to watch their sons play football, but they weren’t penis-health-talk kind of guys.
But penile health—and, more specifically, sexual health—are important. And while I can’t find a stat on how much time men spend thinking about their sexual health and performance, I would wager the answer is “a lot.”Learn more about living with erectile dysfunction ›
