Concern about impotence is positioned first in order of all the sexual worries that men have. Paradoxically, the anxiety itself is the greatest reason of impotence. The cause of impotence of 90% cases of erectile dysfunction is psychogenic factor. Only in 10% cases the problem stems from biological causes.
So if there is not any mechanical damage in a penis, in 90 percents impotence is quite a curable disease. The problem is that to most men it is a taboo topic; that is why most of them stay ignorant about all the achievements of modern medicine. One of the most well-known medications for the treatment of impotence is Viagra. Sometimes you can hear about generic Viagra. Though it is not inferior to branded Viagra in respect of quality and the content is the same, there is a huge difference in price; generic Viagra costs cheaper than the branded one. Since cheap Viagra appeared on the market it has become even more popular. Most men prefer to buy Viagra online. Men are usually sensitive about their erection problems and shy of buying it at normal pharmacies; they feel more comfortable and safe to order Viagra online.
The reason for a weak erection is insufficient blood flow to the penile cavernous tissues. And when there is not enough level of blood flow, the penis cannot get hard. Or, if the cavernous tissues can’t hold the blood this also prevents the penis from expanding to its full size. Viagra intensifies blood flow thereby causing strong and long-lasting erection. It reaches the climax of its action in 30 to 120 minutes after taking. Generally the medication has no serious adverse effects if you keep to the instruction. But it is recommended to consult a doctor before starting taking it to be on the safe side. And of course men suffering from erectile dysfunction should lead healthy life (less alcohol, cigarettes and junk food) not to make things worse.
