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 is maintained. Following sexual arousal, the veins to the penis again open up, allowing the blood to leave

Overview
When men become sexually aroused, hormones, muscles, nerves, and blood vessels all work with one another to create 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 is maintained. Following sexual arousal, the veins to the penis again open up, allowing the blood to leave.
At some point in a man’s life, he may have difficulty achieving or maintaining an erection. Erection problems occur when you can’t achieve or maintain an erection that’s firm enough to have sexual intercourse. For most men, this problem occurs occasionally and isn’t a serious issue. However, if you are unable to achieve an erection one-quarter of the time or more, you may have a health problem that requires medical attention. Erection problems are also known as:
erectile dysfunction (ED)
impotence
sexual dysfunction
