Erectile Dysfunction (ED) is another name for impotence. ED is the inability to get or maintain an erection firm enough to have sexual intercourse. This common problem bears the potential to occur at any time in every man from all ethnicities and ages. However, ED is more likely to emerge as men get older and/or develop other health problems. ED may be an early sign or outcome of various and more serious health issues, including heart and circulatory diseases, diabetes, trauma surgery, radiation therapy, drugs, smoking, alcohol abuse, hormonal imbalances, neurologic and psychiatric diseases as well as psychological problems.
