The world famous little blue pill is something every man has heard of, it’s a magical pill that makes you hard and lets you stay hard for quite some time, but as far as mechanics behind the whole process go, most of the people are in the dark. Here’s a short overview of just how does Viagra affect men’s body and how does it help him keep up with woman in the bedroom.
Viagra itself uses properties of the human body and the way male reproductive system is built. If penis was like any other muscle in the body getting just those muscles stimulated and excited would be a major problem, but lucky for us males, nature has been kind enough to give an erection process a completely stand alone chemical system that can be regulated with targeted chemicals like ones you can find in Viagra. Exactly how does erection occur? When male sees something sexually stimulating, the brain send s signal down a particular nerve and ignites NANC cells which produce nitric oxide.
The nitric oxide stimulates and enzyme in nearby cells that start producing a chemical that relaxes the valve regulating blood flow into penis and makes the valve that regulates blood outflow tighter, chis chemical cGMP is most important one for the process of getting an erection. cGMP has relatively short life time, because after it has been released into the system, another set of commands from the brain activate another cells producing an enzime phosphodiesterase (PDE) which neutralizes effects of cGMP.
Viagra kicks in at this stage of the chemical process, inhibiting PDE enzyme, giving cGMP much longer life and giving males a lot more time to enjoy their erection. You will notice that at no point in this story does the Viagra affect what men finds exciting or not, so an outside stimulant is always important when trying to use Viagra. Also, the Viagra medicine takes some time to get to all of the important bits in the system, so you should take it about one hour before you want the effects.
Now, like all drugs, Viagra has some side effects as well. One of the best know side effects is it’s effect on the vision of the subject. The PDE enzyme is very similar to an enzyme in brain that regulates vision, so it is possible for Viagra to affect the retina of the male, giving his vision a slight blue sheen for several hours. Other then that, one of the side effects experienced are mild to medium headaches. The Viagra drug should not be mixed with other drug prescriptions, especially ones that have something to do with nitric oxide, mix of those drugs could lead to severe heart attacks in worst cases. Also, people with weak heart muscles are advised to try alternative drugs to Viagra since it can take tool on a body.
