Impotence means that a man’s penis doesn’t get hard enough to have sexual intercourse. The man cannot get or maintain an erection. The medical term is erectile dysfunction ED. A man with impotence has either a problem getting an erection or difficulty maintaining one. This usually interferes with sexual activity. Impotence can happen suddenly or gradually. Some men slowly lose the firmness of their erections or how long the erections last. In other men, especially those whose impotence is largely caused by psychological factors, the problem may occur unpredictably.
The penis contains two cylindrical, spongelike structures corpora cavernosa. During sexual arousal, nerve impulses increase blood flow to both of these cylinders. This sudden influx of blood causes an erection by expanding, straightening and stiffening the penis. Erectile dysfunction impotence is the inability to get and keep an erection firm enough for sex. Having erection trouble from time to time isn’t necessarily a cause for concern. If erectile dysfunction is an ongoing issue, however, it can cause stress, affect your self-confidence and contribute to relationship problems. Problems getting or keeping an erection can also be a sign of an underlying health condition that needs treatment and a risk factor for heart disease.
