Levitra vs Viagra : The new pill for erectivle dysfunction is called Levitra. Levitra's makers say a major plus is that it works quickly. In clinical trials, some men using Levitra achieved an erection in 16 minutes. Viagra's maker has responded with studies showing half of men taking Viagra were able to have sex within 20 minutes. The Food and Drug Administration approved Levitra (vardenafil), an oral medication to treat erectile dysfunction in men (impotence). This is the second oral product approved for the treatment of erectile dysfunction. (Sildenafil, better known as Viagra, was the first.) Erectile dysfunction affects millions of men in the United States. Levitra acts by relaxing muscles in the penis and blood vessels, allowing increased blood flow into the penis, which produces an erection. Sildenafil is used for the treatment of erectile dysfunction of either physical or psychological cause. It has been found to be effective in treating erectile dysfunction in men with coronary artery disease, diabetes mellitus, hypertension, depression, coronary artery bypass surgery, and men who are taking antidepressants and several classes of anti-hypertensives. Vardenafil (Levitra) was the second oral medicine approved by the United FDA in the US for the treatment of erectile dysfunction. Like sildenafil (Viagra), vardenafil (Levitra) inhibits PDE5 which destroys cGMP.

Smoking & Impotence Go Together : Men with high blood pressure who smoke are 26 times more likely to have erectile dysfunction - impotence - than nonsmokers. Erectile dysfunction, or impotence, is the inability of a man to achieve an erection or to complete intercourse, he said, and affects an estimated 30 million Americans. Cigarette smoking, hypertension and erectile dysfunction are common disorders in primary care, and informing men who smoke of the exceptionally high possibility of developing erectile dysfunction may motivate many to quit their tobacco habit : the more cigarettes smoked per day the greater the chance of impotence.

Erectile Dysfunction (Impotence or Impotency) : Erectile dysfunction (ED), also known as impotence, is the inability to achieve or sustain an erection for satisfactory sexual activity. Erectile dysfunction is different from other conditions that interfere with sexual intercourse, such as lack of sexual desire and problems with ejaculation and orgasm. Erectile dysfunction (ED, impotence) varies in severity; some men have a total inability to achieve an erection, others have an inconsistent ability to achieve an erection, and still others can sustain only brief erections. The variations in severity of erectile dysfunction make estimating its frequency difficult. Many men also are reluctant to discuss erectile dysfunction with their doctors, and thus the condition is under-diagnosed. Nevertheless, experts have estimated that erectile dysfunction affects 30 million men in the Untied States. Erection begins with sexual stimulation. Sexual stimulation can be tactile (for example, by touching the penis), or mental (for example, by having sexual fantasies). Sexual stimulation generates electrical impulses along the nerves going to the penis and causes the nerves to release nitric oxide, which in turn increases the production of cyclic GMP (cGMP) in the smooth muscle cells of the corpora cavernosa. The cGMP causes the smooth muscles of the corpora cavernosa to relax, and allow rapid blood flow into the penis. The in-coming blood fills the corpora cavernosa, making the penis expand. The pressure from the expanding penis compresses the veins (blood vessels that drain the blood out of the penis) in the tunica albuginea, helping to trap the blood in the corpora cavernosa, thereby sustaining erection. Erection is reversed when cGMP levels in the corpora cavernosa fall, causing the smooth muscles of the corpora cavernosa to contract, stopping the inflow of blood and opening veins that drain blood away from the penis. The levels of the cGMP in the corpora cavernosa fall because it is destroyed by an enzyme called phosphodiesterase type 5.

Impotency causes and solutions : There are an estimated twenty million men in the United States who suffer from impotency at some time in their lives. Impotency is also known as Erectile Dysfunction, or ED for short. It is defined as the inability to achieve or sustain an erection of the penis in order to have sexual intercourse. It doesn't matter what age or race a man is, as impotency happens because of a number of reasons. The usual reasons a man many experience a bout of impotency may include mental stress, physical stress, excessive consumption of alcohol, excessive use of tobacco, fatigue, mental anguish concerning sexual performance, or depression. Another cause of temporary impotency can be a negative side effect from a prescribed medication which the man is currently taking. These types of impotency are usually temporary and end when the cause is found and remedied. If, however, the period of impotency extends beyond a reasonable length of time, a visit to the doctor or healthcare professional is needed. There are many more-serious physical causes of impotency which may include, but are not limited to--diabetes, kidney disease, and a hormonal imbalance. The patient's doctor or healthcare professional will undoubtedly ask some questions about a man's sexual history so that he can properly diagnose the cause of the problem. The patient may possibly be run through a complete medical examination which may include some simple tests. A change of a prescription medicine may be in order if that is found to be causing the impotency problem. Or, if a hormonal imbalance is found, medication can be prescribed in order to successfully treat this problem. There are a number of other medical remedies for men today who suffer from impotency which can be used to alleviate this aggravating problem, also. As for the physical causes of impotency, most men can help to significantly decrease the risk of suffering from this problem by avoiding excessive tobacco use, excessive amounts of alcohol, and abstaining from illegal drug use. Men should try to follow a healthy diet which consists of plenty of fresh fruits and vegetables, whole-grain bread products, and plenty of protein from sources such as lean red meat, milk, yogurt, and cheeses. Another important part of the problems of sexual impotency is the man having an open, honest communication with his spouse or sexual partner. Even though impotency can cause a deep effect on a man's ego, and cause him to have feelings of shame and embarrassment, communication is an essential factor in the healing process. Every man needs to effectively communicate these feelings to his spouse or sexual partner. This openness and honesty will not only enable the spouse or sexual partner to better understand the man's feelings, but it will also enable both the man and his spouse or sexual partner to understand what the problem is and why there is a lack of sexual intimacy existing between them. The man may choose to have his spouse or sexual partner with him when he visits the doctor's office. In conclusion, there can be many causes, both mental and physical, for male sexual impotency. But, a man does not need to suffer with this problem as there are many different medications as well as medical remedies available today to alleviate this problem.
