Viagra prevents impotence

Some urologists say that taking Viagra may protect a man against having erectile dysfunction. Dr. Irwin Goldstein, professor of urology at Boston University Medical School, conducted a research in which it became clear that erections non-consciously encountered in men during sleep are very important to maintain erectile function. The fact is that during erection a big amount of blood flows to the penis enriching it with oxygen and nutrients needed for normal functioning of organs.

With age, nocturnal erections during sleep occur less frequently but men usually do not notice them. According to the results of professor Goldstein, men who often have nocturnal erections would have the overall decrease in sexual function much later in their life. Goldstein pointed out that Viagra increases the number of nocturnal erections, and concluded that this drug is suitable for the preventive treatment of impotence as it can prevent disorders that have not been manifested yet. “A lot of people are taking nitroglycerin to prevent angina attacks, - said Professor Goldstein, answering the question of" The New York Times. "- The same can probably be said about Viagra and erectile dysfunction."

Of course, prevention of future sexual disorders is not the most important purpose of Viagra. Moreover, the theory that regular erections are necessary for proper nutrition and blood supply of the penis, is just a theory. Given its high cost, Viagra is unlikely to become a common "vitamin pill" for those who do not suffer erectile dysfunction but would like to protect themselves against possible trouble in the future. Nevertheless, according to some doctors, regular administration of Viagra prevents the aggravation of sexual disorders in men with moderate erectile dysfunctions.
