But of course there are silver linings in the cloud; advanced researches on this subject are opening up huge possibilities in treating erectile dysfunction---the commonest form of sexual disorder prevalent in the twenty first century men.

While treatment of erectile dysfunction is determined by the cause, you can make independent research to learn about the latest advances in the field. In fact, since late 1990's, the advances in the area of pills for treating ED have been amazing. Here is a brief discussion about the positive role of several pills to treat your ED symptoms.

Although drugs can be injected directly or can be taken as penile suppositories, men typically display a preference for the pills that can be taken orally. These are prescription pills and on the most part composed of selective enzyme inhibitors.

These are called PDE5 inhibitors whose function is to block the action of the enzyme called PDE5. This enzyme is responsible for preventing the smooth muscle of the arteries in the penis from relaxing, or filling the chambers of the penis with blood to make it firm.

The elements in the pills on the other hand increase the level of cyclic guanosine monophosphate (cGMP, a chemical factor in metabolism) and the flow of NO that expands the blood vessels and the whole process of erection gathers momentum.

The most popular oral pills include Viagra, containing sildenafil, Levitra containing vardenafil HCl, Cialis containing tadalafil and Yohimbine and Yocon containing yohimbine as PDE5 inhibitors.

Let's explain briefly how these oral pills work to provide you a problem free sex life.
