Sildenafil is a medical product which restores a natural erection during the sexual arousal.
A normal erection appears during the sexual arousal and release of the nitrogen oxide in the blood vessels. As a result of the vascular diseases, psychological disorders, or other factors, the release of the nitrogen oxide becomes worse, and the blood circulation is not increased in the blood vessels.
Sildenafil activates a strong release of the nitric oxide during the sexual arousal, the vessels of the penis are dilated, and the medicine stimulates the active blood filling of the cavernous bodies. As a result the man can have a strong erection and enjoy intimacy.
Another advantage of Sildenafil is a maintenance of the erection by means of the reduction of the venous outflow. Till the moment of the natural ejaculation, Sildenafil stimulates a high blood pressure in the arterial vessels of the penis, and the man forgets about all problems with potency.
The period of the action of one dose of Sildenafil lasts for about 4-5 hours. This medicine helps to enhance the intensity of the sexual activity because it decreases the recovery time after ejaculation. The man can faster restore his energy and begin another sexual intercourse.
