Erectile dysfunction, in earlier times was considered to be a taboo for men, because of which men never sought any type of medical advice. It was considered to be more of a psychological problem rather than a physical one. As time passed and researches were conducted, it was found that erectile dysfunction can be caused by physical factors such as diabetes, high blood pressure, high cholesterol, atherosclerosis, injury to your spinal cord or nervous system, smoking and excessive consumption of alcoholic beverages.

In 1998, Pfizer developed a pill named Viagra, for treating men having blood pressure problems. During the clinical trials, it was observed that the active ingredient present in this pill, the sildenafil citrate, increased the blood flow in the penis. This action allowed men with erectile problems to have better erections. And since then, Pfizer introduced Viagra sildenafil as the prescription medication for erectile dysfunction, and was the first one to be so. It has helped millions of men in treating their erectile problems and leading a satisfactory sex life.
