Viagra Original

Sildenafil contributes to the enhancement of erection strength and prolongation by blocking the body's production of the PDE-5 enzyme and its vasodilatory action, which increases the blood supply to the penis, specifically to the corpora cavernosa, the structures of the penis that are responsible for erection. It is ingested as directed by your doctor and with plenty of water. This medication has no effect on libido, hormone level or sexual arousal. It also has no effect on the quality or quantity of sperm. Its active ingredient is also indicated to treat pulmonary hypertension. Improper intake or overdose can cause serious side effects: erection that does not disappear, loss of vision in one or both eyes and partial or complete hearing loss. If these symptoms persist, do not hesitate to contact your doctor immediately.
