In simple words, what a Viagra pill does is enable a sexually charged up male to get an erection in spite of being impotent. The story of the drug is amazing - it is a wonderful account of how technology and modern scientific progress can manipulate the human body and make it behave in a particular way under certain circumstances.
Though the solution to impotency is just over two decades old, the problem of sterile men was deep rooted in history, which initially led to penis injection inventions.
It was in the year 1983 that scientists finally established that the erection problem in men was chemical, as opposed to being a mental phenomenon as was widely believed. In the famous 1983 session of the American Urological Association congregation meeting, a well-known scientist Dr. Giles Brindley, injected his penis with a dose of phentolamine, a chemical that caused a heady increase in blood flow to the penis. He dropped his pants and the dumbfounded congregation caught the first glimpse of an artificially induced erection without female presence, proving that penis erections are chemical and not sexual.
The concept behind the injections involved loosening the constricted penis muscles so it absorbs more of blood flow and inflates, hardening itself in the process. Penis injections did not need sexual charge to get erections in men and though many men flocked to get these drugs injected into their penis, they weren't happy about the soreness and pain they were subjected to. Thus, the way to Viagra was paved in the early 1990s.
Pfizer, a US company, undertook research on methods to cure angina, a condition where there is restricted blood flow to different parts of the body and the presence of PDE further clogging the cGMP compounds built up to facilitate blood flow. They, of course, didn't know they were on their way to producing a legend pill!
After years of combined effort, the team discovered a drug, Sildenafil, which was believed to increase blood flow, reduce PDE formation, increase cGMP, and build up nitric oxide. Excited, the team decided to test impotent Ivan Jackson who reported a sudden increase in his penis erection after consuming the pill. Sildenafil was named Viagra and packaged in blue colored diamond-shaped drug tablets to cure impotency in men.
Viagra vs. penis injections
Unlike penis injections, men no longer require inflicting pain on their physique to achieve an erection. Consuming the pill is harmless and if taken under medical supervision, has very few adverse effects produced in the body. Moreover, penis injections produced erections devoid of sexual charge. This pill, on the contrary, will work only if you are sexually attracted to your partner, which is a new lease of life to many males around, incapable of experiencing what it is like to get themselves hardened after beholding a beauty!
There is still a lot of work and research going on to reduce the adverse effects of the drug, so hopefully, this is not the end of the story.
