Erectile dysfunction is caused by insufficient blood flow to the penile tissues. When a penis is erect, the corpa caversona, the two fleshy parts along the penis shaft, are filled with blood. This occurs because the blood vessels within the penis dilate and allow more blood to flow. An erection can be achieved through manual stimulation of the penis and genitals and also through mental arousal or stimulation. Men who have difficulty achieving or maintaining an erection can get Viagra online.
Viagra’s main ingredient, sildenafil citrate, is a PDE5 inhibitor. PDE5 is a natural enzyme in the blood which acts on blood vessels, making them constrict. This constriction of the blood vessels means that the penis cannot become engorged. Viagra inhibits this enzyme allowing the vessels in the penis to dilate, increasing blood flow and producing an erection. It’s easy to order Viagra pills online.
Erectile dysfunction afflicts millions of men every year and can be distressing and traumatic. Men can now easily get Viagra prescribed for them by a doctor or medical professional to enable them to attain an erection. Men who get Viagra prescribed for them take one pill half an hour before intercourse; this is the time it takes for the drug to take effect. They will then be able to maintain an erection for around two hours and in some case it can last up to four hours. When taking Viagra the man should be sexually aroused as the chemicals required for Viagra to work effectively are only present during arousal.
