When a man experiences erectile dysfunction, the question “Why now??” is often frequently followed by the question “Why??” If you have experienced an episode of impotence or erectile dysfunction, it will be important for you to understand some of the mechanics involved. Often enough, finding the underlying cause for your ED will be enough to help you treat it and even cure it very effectively. In some cases however, discovering the cause of ED can take some time with tests and doctors visits, and you can give yourself a jump start on the game by learning as much about it ahead of time. When you understand the basic mechanics of an erection itself, you may be better equipped to deal with the situation should it come back. Knowing how and why this is happening is often a very effective treatment in itself. If ED or impotence is a recurrent problem for you, learn the mechanics of erections now before you consider pursuing other treatment methods. It may surprise you, but erections are much more complicated than they may seem. There are a number of processes that need to happen in your body for this to happen. You need to activate desire in your brain, and simultaneously activate the centers that physically make erection happen.
It is more complicated than you think to simply develop an erection, and then to sustain it as well. For an erection to occur, signals will have to begin within your central nervous system, and these will travel through your spinal cord to the areas that require stimulation. The parts of your physiology that work in an erection are many and include blood vessels, hormones, muscles, nerves, and blood flow, and these parts all work together in a very intricate system that must be coordinated within a strict sequence. There must also be a regular blood flow into the penis in order for the erection to occur. Should there be failure or blockage or issues occurring at any one of these levels, then erections will be blocked and ED will be experienced. For the penis to become erect, the brain must first receive the signal that desire is experienced. Signals of the desire will activate the nervous system to send the signals through the spinal cord with the help of chemicals in your blood known as neurotransmitters. These neurotransmitters will do two jobs, send a signal to your brain that you have desire, and then send a signal to your muscles to relax.
At this point, blood flow will be instructed to increase in the penis itself from the arteries, while the blood that is venous, or from the veins, is pushed out. In essence, this is how the erection begins, and continuous blood flow to the penis will be required to sustain the erection long enough to enjoy intercourse. So long as the desire signals are still activating the nervous system to work effectively, and so long as no interference with any of these parts occurs, an erection will be sustained and intercourse will be enjoyed. While it may seem that desire is the key factor in maintaining and sustaining an erection, you can easily see that it is only one role of many. If you are able to activate all of the correct signals, but still unable to achieve or maintain an erection, then you more than likely have a problem with some wires getting crossed along the way. At the point of an erection where the neurotransmitters work to relax your muscles is the very point in an erection where medication such as Viagra will work. Now that you understand the mechanics of an erection, and how effective treatment can be, you can use treatment such as generic Viagra and find very cheap Viagra online that will get you back into the swing of things in no time.
