How does Viagra


Viagra is a phenomenon. Since the discovery and marketed a decade ago, millions of doses have been sold in almost every country in the world. The drug is also claimed as the first drug to successfully cope with erectile dysfunction or impotence in men.
Although Viagra is associated with 'masculinity', these drugs are not stimulants. This means that Viagra is not able to arouse sexual desire or someone who is no less passionate. These drugs only work if there had been sexual stimulation.
Interesting to understand the workings of Viagra. In addition to knowledge, for the user, can explain what's going on in their bodies.


 
 
How it works Viagra is closely related to the onset of erection. When a man is stimulated or aroused, the brain sends a signal to the sexual organs. Then, the sexual organ will produce a hormone called cyclic GMP. This hormone serves to dilate the blood vessels that line the entry of blood into the sex organs. Due to the widening of blood vessels, then the sex organs will be filled in a lot of blood so that the enlarged, tense, and hardened. This situation is called an erection. During Cyclic GMPdiproduksi in sufficient levels, the erection will be maintained.
However, the body has other mechanisms to balance the effects of cylic GMP. If not, then a man would get an erection again and again. The counterweight is a compound phosphodiesterase 5 (PDE5), which is a compound that can menghancurkanCyclic GMP. With the destruction of Cyclic GMP, the blood vessels will shrink back, so the sex organs will stop having erections.
Viagra (sildenafil citrate) works as an inhibitor (inhibitor) compound PDE5. The logic is simple, if PDE5 is inhibited, the Cyclic GMP will not be tampered with, as a result of blood vessels sex organs continues to widen. This effect continues until sitratdalam decreased blood levels of sildenafil.
Although Viagra seems to work perfectly, it does not mean the drug is suitable for all people or all cases of erectile dysfunction or impotence. Therefore, please consult with your doctor if you will use this drug
. Good Luck….:)).
