What is Erectile Dysfunction (ED)?

Erectile Dysfunction is the term applied to the inability to either achieve or to maintain an erection. This results in an inability to achieve penetration or to ejaculate.

What’s the difference between ED and Impotence?

There is absolutely no difference between the medical definitions of Impotence and Erectile Dysfunction. Erectile Dysfunction is the modern term for the inability to achieve or maintain an erection. Erectile Dysfunction is the term that is always used in the United States while Impotence is used in Europe and Asia.

In terms of implication, however, there is a subtle difference between the terms ‘Erectile Dysfunction’ and ‘Impotence’. Erectile Dysfunction is a far more appropriate term when one considers that 90 percent of men who are suffering from this condition are doing so as a result of a physiological condition. The mechanics of the penis are causing the problem, hence the term Erectile Dysfunction.

Impotence suggests an inability to do something and whilst this might be appropriate in one sense it is inappropriate in that it might also suggest a weakness or something to be embarrassed about. ED is a condition that will affect nearly all men at some stage in their lives and is nothing to be ashamed about. In most cases it is easily treatable and is not the blight that it might have once been before the advent of anti-impotence treatments and medication.

What Happens During an Erection?

The answer to this question might seem obvious. On a very basic level, all men know what happens to a penis when it becomes erect. The actual mechanics of achieving an erection and the changes which take place in the body and brain of the person having the erection are, however, extremely complex. This is, of course, why things are prone to go wrong at sometime or other. This is a completely normal occurrence.

An erection occurs in response to signals from the brain. The main physiological change occurs when two tubes which run the length of the penis fill with blood. These two tubes are known as the corpora cavernosa. They are made up a sponge-like material, which is largely composed of muscle fibres. When the penis is flaccid these muscle fibres are contracted and empty, rather like a dry sponge. When signals arrive from the brain telling the penis to become erect these muscle fibres relax allowing blood to fill the spongy tissue. This also compresses the veins that would, normally, take blood away from the penis. As a consequence the penis swells with blood and becomes hard.

The corpus spongiosum is a single tube that can be found just below the corpora cavernosa. This contains the urethra through which passes urine and semen. This may also become filled with blood but to a lesser extent than the corpus cavernosum. When a man has ejaculated his erection will normally disappear. The time that this takes is dependent on the length and girth of the penis.

A man may also have an erection as the result of a full bladder or during his sleep. Normally this would occur during REM sleep. The scrotum also becomes tighter during an erection.
