The erection mechanism
For a perfect understanding of how Canadian Viagra works, you must also understand the process of erection and the penis’ anatomy. The penis has three cylindrical masses of tissue. The top two of them are the corpora cavernosa, while the lower one is the corpus spongiosum. The top two masses constitute the penis’ bulk. Tunica albuginea surrounds all three sections. When you have a cross-sectional view of a male’s penis, it will resemble you a sponge which lacunar spaces are filled with blood when the penis is erect. Penile artery and the urethral artery supply blood to the penis. It brings blood to each of the penis’ section. Helicine arteries carry blood out of penis (its divisions). Sympathetic nerve stimulation results in contraction of erectile tissue – it provides the flow of blood inside the penis, and the penis becomes flaccid. Parasympathetic stimulation brings relax to erectile tissue, and lacunar spaces are filled with blood: it causes an erection. However, the process of erection starts only (!) when a brain sexual stimulator exists. The brain signal comes to the spinal cord and then to the genital area. There various chemical processes involving nitric oxide happen. When the vessels and arteries are weak and cannot bring blood to and out of the penis, the erection does not occur. When a man has constant problems getting an erected penis, ED is diagnosed.
Viagra helping men with ED
Many guys suffering from various heart diseases have weak vessels. They do get ED often. Men with atherosclerosis, kidney diseases, and hypertension also get these troubles. The best Canadian Viagra increases the level of nitric oxide and starts all these chemical processes, which lead to an erection. The relaxation of smooth muscles is also enhanced. The erection is gotten and maintained up to 3-4 hours of taking a tablet of the stuff. Canadian Viagra does not show any direct effect on the penis arteries or its tissue. It shows no effect in sexual stimulation.
Today, men who find the best Canadian online pharmacy Viagra, start ordering this stuff for ED to save money. Saving more, guys can let themselves have more sexual intercourses (as natural Viagra is too pricey). The oral therapy with Sildenafil (Viagra) proved its effectiveness. It is still the best alternative to surgery and all other ways of getting rid of ED.
