Viagra improves the blood supply to the penis by growing the deposition of the nitric oxide in the penile area that open up the arteries and veins that supply blood to the penis.
In a non-erect state, the arteries that transport b­lood into the corpora cavernosa are somewhat constricted, whereas the veins that drain the blood from the penis are open. An erect penis is extraordinarily mandatory for a sexually satisfying experience. It really works to promote blood move in penis.
Drinking alcohol or smoking may also lower blood circulate to your penis, making Viagra less effective or shorter-lasting. However, these medications constrict your blood vessels, which may interfere with an erection. However, in case your doctor has prescribed Pfizer Viagra one hundred mg to be taken at particular duration then be sure to comply with the prescription. The nitric oxide then releases the cGMP enzyme which in flip relaxes the smooth muscles of the penis.
When a man who has erectile dysfunction is aroused, the nitric oxide and the cGMP enzyme is released. However, in addition to those two important parts, one other enzyme, phosphodiesterase-5 (PDE-5), is launched. Once aroused, nitric oxide (NO) is released into the bloodstream.
