| Erectile dysfunction (ED), also called impotence, is the inability to attain or sustain an erection until ejaculation. Erectile dysfunction is different from other medical conditions that intervene with sex life, such as lack of sexual desire and problems with ejaculation and orgasm.
Erectile dysfunction (ED) varies in severity: some males have a total inability to achieve an erection, others have an irregular ability to achieve an erection, and still others can maintain only brief erections. The variations in severity of erectile dysfunction make it hard to estimate its frequency. Many males are also reluctant to speak about this sexual disorder with their physicians, and thus the health problem is under-diagnosed. Yet, according to estimates, 30 million men in the USA have ED.
While erectile dysfunction can happen at any age, it is uncommon in young males and is frequently diagnosed in the elderly. By the age of 45, most men have suffered from ED at least a few times. Still, if the problem becomes chronic, it can have adversely influence relationships, emotional health, and self-esteem.
In the recent decades, the medical perspective on the causes of erectile dysfunction has shifted. Impotence was commonly believed to be triggered by psychological factors. Now medical practitioners assume that up to 85% of ED cases are caused by medical or physical problems. They include vascular problems, hypertension, diabetes, neurological disease and other health conditions. Some of the medications used to treat these conditions can also trigger ED. Only 15% of ED cases are grounded on psychological factors. They include anxiety, depression, stress, and problems in relationships. At times impotence is due to a combination of physical and psychological factors. Lifestyle can adversely impact on men's sexual well-being and virility, too. Smoking, alcohol use, and other substance abuse can increase the risk of erectile dysfunction.
Advances in medicine have helped increase the number of methods available to treat male impotence effectively. Drug therapy of PDE5 inhibitors is the main treatment for erectile dysfunction. Sildenafil (Viagra), vardenafil (Levitra) and tadalafil (Cialis) are the three drugs approved for treatment of ED.
The blue little pills were initially introduced to cure heart disease and preclude heart attacks. It was concluded that the pills could relax blood arteries. Angina was believed to decrease if more red blood cells carrying oxygen were delivered to heart muscle cells via the dilated cardiac vessels. Not only were cardiac arteries widened, but so were blood arteries in other places. This side-effect was taken into consideration when treatments for male impotence were being invented.
Alongside the drug therapy, there are other forms of treatment. The cause of sexual disorder and a man's lifestyle determine the treatment a doctor opts for. |
