 | | | Can viagra help male impotence?If you suffer from male impotence (or Erectile Dysfunction - ED) can Viagra really help you overcome this very personal problem? How does Viagra work? ARe there any side effects?
Basically Viagra enables men with ED to respond to sexual stimulation. Male impotence is caused by a lack of bloody circulation in the penis, Viagra increases blood flow to the penis so that when a man is sexually aroused, he can get and keep an erection.
When sexually aroused, arteries in the penis relax and widen, therefore allowing more blood to flow into the penis. As the arteries in the penis expand and harden, the veins that normally carry blood away from the penis become compressed, restricting the blood flow out of the penis.
With more blood flowing in and less flowing out, the penis enlarges, resulting in an erection. If the nerves or blood vessels associated with this process aren't working properly, a man may not be able to get an erection. Once the sexual encounter is over, the erection goes away.
Viagra really can improve erections in up to 4 of 5 men compared to 1 out of 4 who took a placebo and it can be effective in as little as 30 minutes and stays effective for up to 4 hours.
Always refer to a medical practitioner before you undertake any change of medication or start a new medication course. | | | |
