What is erectile dysfunction?
Erectile dysfunction (ED) is a type of penile disorder. It affects your ability to get and maintain an erection firm enough for sexual intercourse.

Your feelings play a major role in getting and maintaining an erection. Feeling relaxed, confident and aroused is essential. But it’s normal to sometimes have erection issues. Erection problems can occur if you feel nervous, anxious, frustrated or tired. Drinking alcohol and/or using substances can also have an effect. It can also result from other conditions or as a side effect of certain medications or cancer treatments.
