Erectile Dysfunction (ED)
Being unable to get or keep an erection most times you have sex. Doctors call this "impotence" or "erectile dysfunction."
Men can have trouble getting or keeping an erection if they have a condition that keeps the penis from getting enough blood. Things that reduce blood flow to the penis can include:
High blood pressure
Drinking alcohol or taking drugs
Sex problems can also occur when men feel depressed or worried, or have problems with their partner or relationship. Plus, sex problems can be a side effect of certain medicines. For example, medicines to treat depression or heart disease sometimes cause sex problems.
