After ejaculation, the male body becomes capable of repeated ejaculation only after a while. This time interval between two ejaculations is called a refractory or latent period.
As a rule, the older a man, the longer the latent period lasts. Some men in the days of youth could have ejaculation for four or five times for a night and did not notice any "latency" periods.
But it is due to the fact that the latency period of such people is very short they could make several sexual acts in a short time.
When a man grows older, ejaculation gives him no less pleasure than in his youth ... But, he reaches orgasm not so often, as before. Refractory period lengthens: at the age of 20 you lost for 30 minutes for it, and now, when you are under 40, the refractory period stretched to 3 hours for example.
Of course, because of this, the frequency of possible orgasms is reduced.
Talking about changes that occurred with the body under the influence of Viagra (Sildenafil), some men reportedabout fairly rare phenomenon: because of Viagra (Sildenafil) the refractory period became rather shorter.
And thanks to this, men who usually had only one ejaculation per night, began to notice that with the same degree of excitement sometimes they get an erection and ejaculation two or even three times per night!
But unfortunately the effectiveness of Viagra (Sildenafil) in this area is limited by natural causes.
After taking the pill Viagra (Sildenafil), the effect of the drug lasts for four hours, after which the concentration of the drug in the blood decreases and its effect is much less.
And if for example you have the refractory period for 15 hours, then Viagra (Sildenafil) does not have time to affect it, because it will be removed from the body much earlier.
However, if the duration of the refractory period is about 5 hours, then under the influence of this medication it may well be reduced to 1-2 hours.
Some urologists say that intake of Viagra (Sildenafil) can prevent from the appearance of erectile dysfunction.
Dr. Irwin Goldstein, a professor of urology at the faculty of Boston University School of Medicine, conducted a study that made it clear that erections unconsciously occurring in men during sleep are very important for maintaining an erectile function.
Because with erection the penis receives a large amount of blood rich with oxygen and nutrients necessary for the normal functioning of organs.
Of course, prevention of future sexual dysfunctions is not the most important purpose of Viagra (Sildenafil). Moreover, the theory that regular erections are necessary for normal nutrition and blood supply to the penis remains just a theory.
Considering its high cost, Viagra (Sildenafil) is unlikely to become a common "vitamin pill" for those who do not suffer from erectile dysfunction, but would like to be safe from possible troubles in the future.
Nevertheless, regular intake of Viagra (Sildenafil) prevents the aggravation of sexual disorders in men with moderate erectile dysfunction.
