In older men, ED usually has a physical cause, such as disease, injury or side effects of drugs. Any disorder that causes injury to the nerves or impairs blood flow in the penis has the potential to cause ED. Incidence increases with age: About 4% of men in their 50s and about 17% of men in their 60s experience a total inability to get an erection; the incidence jumps to 47% for men over 75. But ED is not an inevitable part of aging.
ED is treatable at any age, and awareness of this fact has been growing. More men have been seeking help and returning to normal sexual activity because of improved, successful treatments for ED.
Erectile dysfunction is a condition in which a man can't get or keep an erection that's hard or long enough to have sex. Every man occasionally experiences the inability to get an erection, and that's perfectly normal. However, if it's something that happens frequently, it's called erectile dysfunction (ED). ED can be caused by a number of physical and psychological factors, and its symptoms can range from mild to severe. Fortunately, there are many options for treating this condition.
Erectile dysfunction (ED) or impotence is the inability to maintain an erection that is firm enough or that lasts long enough to have successful sexual intercourse. It is a frustrating condition that may have psychological, medical or physical causes. Nonetheless, there are many types of sexual dysfunction that may be confused with impotence.
Impotence does not mean premature ejaculation, low sex drive, or infertility. It is not caused by masturbation or too much sex earlier in life. While impotence is common with most men sometimes in their lives, it is not normal and can be easily treated.
