Sexual impotence, or erectile dysfunction, is a condition characterized by a man's repeated inability to achieve or maintain an erection suitable for sexual intercourse. It commonly affects sexually mature males, usually due to underlying medical or psychological conditions. It can be caused by alcohol abuse, smoking, hormonal deficiency, or diseases like diabetes and cardiovascular disease. Psychological impotence can be caused by depression; feelings of anxiety or nervousness; stress from work, family or financial problems; unresolved issues between sexual partners; feelings of self-consciousness; and fearing a partner's reaction or rejection.
One of the most popular treatments for sexual impotence are prescription oral phosphodiesterase type 5 (PDE5) inhibitors such as Viagra (sildenafil), Cialis (tadalafil), and Levitra (vardenafil) which are reliable, non-invasive and conveniently packaged in pill form. These drugs work by blocking the enzyme known as PDE5, which breaks down the chemicals that cause the erectile response. PDE5 inhibitors work by relaxing smooth muscle tissue in the blood vessels of the penis enabling their dilation and increasing blood supply to the corpus cavernosum, thus allowing the penile shaft to engorge and stay firm for a longer period of time. But contrary to popular opinion, these drugs do not directly create an erection in the penis, instead requiring sexual stimulation in order to work. However, it does increase the sensitivity of the male sexual organ.
Although these medications have been hailed as a wonder drug by impotent men worldwide, PDE5 inhibitors are not without its complications. Numerous side effects such as headache, nausea, vomiting, indigestion, muscle pains, flushing of the face and body, runny nose, palpitations, and vision disturbances have been observed in some patients. However, there has been some evidence that these side effects diminish with prolonged use. It is also not recommended for patients taking nitrate-based drugs or alpha-blockers, because interaction between those prescriptions with PDE5 inhibitors can be fatal in some cases.
As with any medication, PDE5 inhibitors have both positive and negative effects on the body. If you are suffering from sexual impotence and did not achieve an erection upon taking Viagra, Cialis, or Levitra for the first time, please consult your doctor. He can give you a different prescription medication that is more suited to your physiology. Don't just give up.
