First things first: Viagra is not a miracle drug. It's not a cure-all for sexually transmitted diseases, cancer or infertility. It cannot function as a contraceptive because that is not its intended purpose. It cannot replace couples counseling and it will not give you a raging erection when you don't feel any desire to have sex. Viagra is neither an aphrodisiac nor a hormone like testosterone.
On the other hand, where erectile dysfunction (ED) is the problem, Viagra (generic or otherwise) is the perfect pill for the job. As men age, hormone levels change, much like what happens to women during menopause. The presence of other health factors also contribute to a man's inability to "get it up." In these cases, generic Viagra can help by:
- Increasing the amount of nitric oxide produced in the penis
- Increasing the amount of cGMP produced in the penis as a result of increased nitric oxide amounts; and
- Eliminating PDE in the penis, which then contributes to the accumulation of cGMP, that is responsible for producing erections.
