Buy Viagra Without Prescription
Erectile dysfunction is very common among men of all age groups. Although this condition affects men over sixty up to four times more than younger men, this condition is experienced by 1 in 10 men worldwide. For this reason, Viagra was developed and it has helped millions of men achieve and maintain erections during sexual activity. Viagra was originally only available with a doctor’s prescription, but now it is possible to buy Viagra without prescription. Erectile dysfunction has many causes ranging from stress to depression and it can contribute to lack of self-esteem when it occurs on a regular basis. Erectile dysfunction can cause a strain in relationships and lead to marital discord, fortunately though Viagra without prescriptions can help.
How Viagra works
Since Viagra has been on the market it has helped men to successfully overcome this condition. An erection occurs when a man is aroused either physically or visually. The arousal causes the blood vessels in the penis to dilate and send extra blood flow into the area. This causes the penis to become stiff and swollen and results in an erection. Normally men are able to maintain their erection until they ejaculate or are no longer sexually aroused. The blood flow to this area is unimpeded and erections can remain during sexual activity. In some men the blood vessels in the penis contract so that there is no possibility of achieving or maintaining an erection. The reason for this has to do with a naturally occurring enzyme called phosphodiesterase type 5, or PDE5. This enzyme is responsible for the contraction and constriction of blood vessels in the penis. Viagra was developed to inactivate PDE5 and act as an inhibitor to this enzyme. When the enzyme is no longer active it cannot contract blood vessels in the penis and as a result the blood vessels can dilate and blood can flow into the penis. Sildenafil prices will vary slightly depending upon where you decide to get your prescription.
Viagra is also prescribed for people with very high blood pressure because it has the ability to increase blood flow. When obtaining Viagra for erectile dysfunction it is possible to buy Viagra without prescription. Men who buy Viagra without prescription take 1 pill half an hour before they engage in sexual activity. This is because Viagra takes half an hour to become effective. Viagra will not work if the man is not sexually aroused. When the man is sexually aroused the pill quickly takes effect and erections can be achieved and maintained anywhere between 2 to 4 hours. The erection will subside when the man has ejaculated or is no longer sexually aroused.
