Erectile dysfunction: Causes and treatment
Most men will experience problems getting or keeping an erection at some point during adulthood, but this is not always caused by a medical problem. However, some men do develop a medical condition called erectile dysfunction.
Erectile dysfunction (ED) is a condition that occurs when the penis does not receive enough blood to produce an erection that is capable of having sexual intercourse. For men with ED, this happens repeatedly and affects a man's ability to sustain an active sex life.
