The penis contains two cylindrical, sponge-like structures corpora cavernosa. When a male becomes sexually aroused, nerve impulses increase blood flow to both cylinders. This sudden influx of blood causes an erection by expanding, straightening and stiffening the penis.
Medication can effectively treat symptoms, but taking overall health seriously is critical. Maintaining good health by following a healthful lifestyle, and managing medical conditions before they cause irreversible damage, is the key to getting a solid erection and maintaining throughout life. Medications may be helpful for men with ED, but the best long-term approach is to manage the causes of ED and not simply treat the symptoms.
An erection problem occurs when a man cannot get or keep an erection that is firm enough for intercourse. You may not be able to get an erection at all. Or, you may lose the erection during intercourse before you are ready.

It tends to get too excited for its own good. It responds poorly to illicit substances. It can show up in a big way at inopportune times, while retreating from duty when you need it most.
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.
An erection clinically: penile erection or penile tumescence is a physiological phenomenon in which the penis becomes firm, engorged, and enlarged. Penile erection is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is often associated with sexual arousal or sexual attractionalthough erections can also be spontaneous. The shape, angle, and direction of an erection varies considerably in humans.
Back to Men's health. The medical name for having an erection that won't go down is priapism. It happens when the blood that fills the penis to make it erect gets trapped and cannot flow back out again. Priapism can be extremely painful.
Most of us know that the to learning to how to have great sex is seeing it as a joyful, fun, and energetic release for men and women alike. But for some men, especially as they age, the fun is zapped from the equation because they are worried about possible erectile dysfunction, impotence and making sure their penis can get and stay hard. But as he ages and erections don't come the way they used to, sex can become less about intimacy and more about proving that his penis can still get hard without any issues or problems.
The discovery of the biochemical chain of events that keeps a male penis erect after the initial response may lead to new therapies to help men with erectile dysfunction. In our research, we wanted to understand what happens next to enable that erection to be maintained. It turns out that nitric oxide is also involved in that complex process, senior author Burnett and colleagues report in an article published online by the Proceedings of the National Academy of Sciences.
