Viagra tablets and the treatment of erectile dysfunction

Much has been written about erectile dysfunction. Erectile dysfunction (or impotence as it is also know) is the condition that occurs when a man is found to be unable to develop or retain an erection as required for the achievement of sexual intercourse. Men that suffer from erectile dysfunction may be able to experience mental sexual stimulation; however they will be unable to translate this into an erection.

The condition of impotence is hardly an uncommon problem. For instance, in the United States alone it is estimated that as much as 15 million men suffer from varying degrees of impotence. This equates to 2 out of every 10 men in America. However, cases of erectile dysfunction are found to increase through the age demographics. This results in a 1 percent ratio for men below the age of 30. 7 percent found in men between the ages of 45 and 55 and as much as 75 percent for men who are above the age of 80.

In treating impotency, doctors classify the condition into two categories: Primary impotence and secondary impotence. Primary impotence is attributed to individuals who develop erectile dysfunction whilst still in the early years of adolescence. Such individuals are normally with an established sexual history. Secondary impotence on the other hand is used to categorize cases where impotence is found to develop after an established period of erectile ability.

During the male erection, the penis of a man is found to become erect and rigid. This permits the act of sexual penetration. The length of the male penis when fully erect is found to vary, however 6 inches is agreed to be the average length. Erections are dependent on the flow of blood amongst other things. The amount of blood flowing into the penis during its erect stage is found to be more than 7 times that which is experienced when it is in the flaccid state. To ensure that the penis is provided with sufficient blood content, the rate of blood flowing into the penis is found to be significantly greater than the blood flowing out of the penis. The veins responsible for the outflow of blood are found to constrict during an erection, only opening after ejaculation has occurred.

In treating impotence, Viagra ensures that the penis receives adequate by expanding the various blood vessels associated with the flow of blood.  Most physiological causes of erectile dysfunction are caused as a result of insufficient of blood flow into the penis. By taking Viagra tablets these symptoms are effectively treated.
