Buy Sildenafil Online Without a Prescription
When a man is sexually aroused either physically or mentally a set of chemical reactions take place in both the brain and the blood, the end result is an erection. The erection is caused by the engorgement of the corpa cavernosa, the two fleshy tissues that span the length of the penis shaft. The corpa cavernosa become engorged with blood due to an increased blood flow as a result of the penile arteries and blood vessels becoming dilated. The dilation of the blood vessels is crucial in a man’s ability to get an erection; men with erectile dysfunction have an inadequate supply of blood to the penis due to constricted blood vessels. For these men who suffer from ED, they are now able to buy Viagra without prescription through reputable online pharmacies.
The blood vessels are constricted by the phosphodiesterase type 5 enzyme, or PDE5, a naturally occurring enzyme in the body which acts as a vasoconstrictor. Sildenafil no prescription medication is a type of PDE5 inhibitor which attaches itself to the enzyme and prevents it acting on the blood vessels, effectively rendering it inert. The blood vessels can then dilate and the blood flow is then increased sufficiently to produce an erection. An erection will only occur if the man is sexually aroused as the PDE5 which the drug affects is only present during arousal.
