KNOW MORE ABOUT MEN'S SEXUAL PERFORMANCE.
Erectile dysfunction is characterized by the regular or repeated inability to obtain or maintain an erection. It is analyzed in several ways. Erectile problems occur when you cannot achieve an erection that is firm enough to have sexual intercourse. For most men, this problem occurs occasionally and is not a serious issue. However, if you are unable to achieve an erection 25 percent of the time or more, you may have a health problem that requires attention. Erection problems are also known as: Erectile dysfunction (ED), Impotence, OR Sexual dysfunction.
When men become sexually aroused, a number of hormones, muscles, nerves, and blood vessels all work in conjunction with one another to signal an erection. Nerve signals, sent from the brain to the penis, stimulate muscles to relax. This, in turn, allows blood to flow to the tissue in the penis. Once the blood fills the penis and an erection is achieved, the blood vessels to the penis close off so that the erection can be maintained. Following sexual arousal, the veins in the penis again open up allowing the blood to leave.
Anything that interferes with this process can lead to impotence and can include; arteriosclerosis, peripheral vascular disease, the use of certain medications, alcohol or cigarettes, a history of sexually transmitted disease and chronic illness such as diabetes and high blood pressure.
