Impotence and Erectile Dysfunction - What does it mean?
A explanation about impotence and erectile dysfunction
Impotence can also be called Erectile Dysfunction. It refers to the inability of a man to maintain an erection during sex. It can include a reduced sense of sexual excitement, which in turn leads to a loss of an erection.
Getting An Erection and Love-Making
A man must be sufficiently aroused by one or more means to enjoy a firm erection. The arousal can be psychological or physical or even both together.
Most often the stimulus can be what he sees or senses or even hears from his partner. On the other hand it can be his imagination producing thoughts and images that are of a sexual nature. Generally it is a combination of the both fantasy and reality.
Erections That Are Involuntary
Virtually all men will experience what might be called involuntary erections. This means that a man will experience an erection that he has not chosen to have at that time. Most often a man will notice an involuntary erection when waking in the morning and before emptying his bladder. Overnight the bladder fill with urine and puts presses on the prostate gland. Stimulating the prostate gland leads to sexual arousal and an erection.
Similarly, there will be other times whether awake or asleep that a man will get an erection that is involuntary. Occasionally a man will be aroused by another person he has contact with. He will not seek to have an erection but because he is sexually stimulated he will experience an erection.
What Happens To Achieve An Erection?
Inside the un-erect penis there are three empty chambers. These chambers fill with blood and the penis becomes stiff and erect. The penis grows longer and gets wider too.
When sexual stimulation (physical or imagined) or involuntary stimulation happens, the brain sends to the body a message to increase the flow of blood to enlarge the penis. In the penis the three chambers fill with blood and with increased blood pressure an erection is achieved.
For the duration of sexual arousal, the penis will stay enlarged and blood is stopped from escaping from the penis by muscles at the base.
Interestingly the nervous systems of the body play an important part in all of this. The parasympathetic and the sympathetic nervous system are the two in question. Usually only one of these systems dominates at any one time. However to achieve an erection the two systems work together.
This information can provide a better idea of how impotence or erectile dysfunction arises. If a man experiences anxiety during sex it can alter the balance between the parasympathetic and the sympathetic nervous system and lead to the loss of an erection.
Therefore impotence or erectile dysfunction is the loss of an erection through to ejaculation or desired completion of satisfaction for both partners.
