How is it working?
Erection is primarily caused by filling the penis with blood. To use it, blood vessels should open in the penis to allow blood to flow. During sexual pleasure, the body produces a chemical called cGMP (cyclic guanosine mono-potassium sulfate), and this cGMP tries to open the blood vessels in the penis. The enzyme PDE5 falls down cGMP and prevents it from doing its job. What Cialis and other PDE5I do is avoid the rundown of cGMP also by the PDE5 receptor. Therefore, when there's more cGMP in the penis, the blood vessels open and the patient is better constructed.
