To understand better about erectile dysfunction, it is important to understand how a normal erection occurs. Contrary to popular belief, the brain is the biggest sexual organ and aware of erections which are the result of a pulse sent by the brain to the central nervous system. The nervous system then tells the party’s muscular corpora cavernosa of the penis to relax. Once the corpus cavernosum called the tunica albuginea gets filled with blood, the muscular corpus cavernosum then expands. The enlarging the corpora cavernosa resultis in an erection.
The draining of blood from the tunica albuginea and the resultant relaxation of the corpus cavernosum results in a loss of erection. One of the leading causes of erectile dysfunction is the lack of proper blood flow to the corpus cavernosum. Erectile dysfunction can thus occur due to low blood pressure, diabetes and rarer conditions like cardio vascular leakage. Today, drugs like Cialis have made it possible to treat previously untreatable erectile dysfunctions and are helping millions of people lead a normal and healthy sex life. Erectile dysfunction is the basis of a multi-billion dollar industry. What is also equally true is that Cialis and Viagra are perhaps the most effective treatments for erectile dysfunction today. Compared to other techniques like surgical implants and pumps, drugs are a simpler and safer means of treating erectile dysfunction.
It is important to understand that not all erectile dysfunctions can be treated by drugs, in fact, not all erectile dysfunctions are caused due to physical problems. Mental stress and psychological problems too lead to erectile dysfunction. In addition, excessive drinking is also a known cause of erectile dysfunction and impotence.
