Erectile dysfunction describes a condition in which a male is no longer capable of maintaining an erection long enough for sexual intercourse. Anywhere from 15 to 30 million American men currently suffer from some form of erectile dysfunction. Either they are entirely unable to achieve an erection, reach one sporadically or can only sustain them for a brief period of time.
Causes of and Ways to Treat Erectile Dysfunction
There are are many causes of erectile dysfunction, both physical and mental. Any damage to nerves or muscles, whether from an accident, surgery or disease can have a direct impact. Diabetes, for example, has been shown to be one of the major causes. Additionally, certain medications, such as antidepressants and antihistamines, have numerous sexual side effects that can be to blame. Finally, mental anxiety such as guilt or low self-esteem can play a major role.
One of the primary means of treating erectile dysfunction involves the use of a number of newly developed drugs. In 1998, Viagra became the first FDA approved pill for the treatment of erectile dysfunction and in 2003. The drugs Levitra and Cialis were also approved. All of these drugs work by enhancing the levels of nitric oxide in the body, which plays an important role in relaxing certain muscles and improving blood flow to the penis.
Drugs such as Viagra, Levitra and Cialis should never be taken more than once a day. Even more importantly, individuals who take certain types of nitrate-based heart medications should never use them as the combination could provoke severe decreases in blood pressure. Finally, Levitra should not be combined with alpha-blockers as similar life threatening conditions can occur.
Male impotence is defined as the inability to maintain an erection or reach ejaculation. In the United States it is estimated that close to 30 million men are confronted with this condition. For many years there was little that could be done, but fortunately recent medical discoveries have led to the creation of a number of effective drugs.
Treating Impotence
About 85 percent of all reported cases of impotence are caused by physical ailments, while the remaining 15 percent are split between psychological and unknown reasons. Heart problems, diabetes or prostate cancer are but a few of the possible physical ailments that can lead to impotence. Because of the varying causes, there are a variety of ways to treat the condition. Nevertheless, certain prescription drugs have become the remedy of choice over the last few years.
To understand how drugs such as Viagra, Levitra and Cialis work, it is important to comprehend how the male erection functions. As a man is sexually excited, the arteries in the penis have a tendency to relax and widen, allowing for greater blood flow. The veins that are then supposed to evacuate blood from the penis are compressed, leading to more blood being pumped in then out and, therefore, leading to an erection.
In cases of impotence, this complex system of blood flow is typically disrupted. Viagra, Levitra and Cialis work by increasing the amount of blood flow to the penis, therefore compensating for this problem. Each drug works for a different periods of time. Cialis, for example, is effective for over 30 hours. Nevertheless, these drugs do not cause an individual to have an erection. Instead, they are designed to help a man maintain one as long as he is sexually stimulated.
