Viagra Is a Blessing to Men’s Lives
According to the current research, human beings have three radical desires, which are sleep, appetite and sex. Those three things are significant to people’s lives. However, in this contemporary world, numerous men cannot enjoy one of their radical desires, which is the sex drive. A lot of men are having serious sexual capacity problems; a typical issue is impotence. Therefore, a great deal of medicine companies tried to solve this problem. Viagra is an important product because of its history, popularity and effects.
Innovative inventions totally have changed human beings’ lives and many inventions were invented by accident or mistake. Originally, Pfizer researched for use in high blood pressure and stricture of the heart, but researchers found that the drug has outstanding effect on penile erections. Hence, Pfizer determined to market for impotent patients and in 1998, Pfizer obtained the United States’ (F.D.A) approval. Focusing on Pfizer’s sales strategies, “Even though Viagra is available only by prescription from a doctor, it was advertised directly to customers on U.S TV (famously being endorsed by former United States Senator Bob Dole and football star Pele). A great deal of sites on the internet offer Viagra for sale after an “online consultation “, often a simple web questionnaire. The “Viagra” name has become so well known that many fake aphrodisiacs now call themselves “herbal Viagra” or are presented as blue tablets imitating the shape and color of Pfizer’s product. Viagra is also informally known as “Vitamin V”, “The Blue Pill”, “Blue Diamond” as well as various other nicknames”. (Wikipedia)
When Viagra was invented by Pfizer, all men cheered for it and Porn film director defined that Viagra is a blessing to humankind. Firstly, the main reason is that men can have erection of their own free will without regard to time and place. This situation simply means that men can recover their confidence through Viagra.

Lastly, People may undergo sexual dysfunction, because of their illness or as a consequence of their treatment. In conformity to research work, Viagra improved sexual function in men in this case. Turning to female cases the same doctor found that Viagra also improved sexual function in female patients. This is also especially worthy of notice; Viagra is even used in sports. The reason is that they believe that it will strength their performances.
In order to understand why do people experience impotence and need Viagra. It is informative to understand the fundamental facts about erection. In accordance with research reports, the brain reacts to images and the erection center of the spine reacts to body contact. When the central nervous system is sexually stimulated, it sends a signal to men’s genitals. “These signals cause the secretion of a chemical (nitric oxide) in the body that works to induce a relaxing effect in the muscles of the penis. These muscles, otherwise, stay in a constricted state. This is to stop blood from flowing into the penis. But when the muscles get relaxed, a large amount of blood gushes in the nerves of the penis resulting in an erection. Now this erection is lost when another chemical (phosphodiesterase type 5) is produced by the body to cease the effect of the nitric oxide. When this chemical is released, blood flow is stopped, and the penis loses its erection, and becomes flaccid”. (Buzzle) Viagra is used for the cure of impotent
