What are the different types (and causes) of ED?
By: William E. Franks, Mon Jan 11th, 2010
The following are some of the different types of impotence and its possible causes many des these situations have reverted to buy viagra and use it to revertuir these evils as:
Premature ejaculation
Premature ejaculation is the inability to maintain an erection long enough for mutual satisfaction. Premature ejaculation is divided into primary and secondary schools:
Primary premature ejaculation
Primary premature ejaculation is a learned behavior that the man in the beginning of his active sex life. Like any behavior that is learned, it can modify. This form of primary PE is called psychogenic impotence (as opposed to organic or physical). (Congenital venous leak is a subset of primary PE is caused by a congenital venous leak in which the venous drainage of the penis does not close properly.)
Secondary premature ejaculation
Secondary premature ejaculation occurs when, after many years of normal ejaculation, the duration of intercourse grows progressively shorter. Secondary premature ejaculation is due to physical causes, usually involving the penile arteries or veins or both.
Performance anxiety
Performance anxiety is a common form of psychogenic impotence, usually caused by stress or anxiety.
Depression
Depression is another cause of psychogenic impotence. Some antidepressant medications cause erectile dysfunction.
Organic impotence
Organic impotence involves the penile arteries or veins or both and is the most common cause of impotence, especially in older men. When the problem is arterial, it is usually caused by arteriosclerosis or hardening of the arteries, although the cause could be a trauma to the arteries. The controllable risk factors of atherosclerosis (excess weight, lack of exercise, high cholesterol, high blood pressure and cigarette smoking) can often cause erectile dysfunction before affecting the heart. Many experts believe that when veins are the cause, a venous leak or "cavernosal failure" is the most common vascular problem.
Diabetes
Impotence is common in people with diabetes. The United States has 7.8 million adult men with diabetes and it is estimated that 35 to 50 percent of them are impotent. The process involves premature and unusually severe hardening of the arteries. Usually, people with diabetes may suffer from peripheral neuropathy, which affects the nerves that control erections.
Neurological causes
There are many causes neurological (nerve problems) from impotence. Diabetes, chronic alcoholism, multiple sclerosis, heavy metal poisoning, injuries to the spinal cord and nerves, and nerve damage from pelvic operations can cause erectile dysfunction.
Impotence caused by medications
A variety of prescription drugs, as drugs for hypertension, antidepressants and drugs for anxiety, eye drops for glaucoma and cancer chemotherapy agents are just some of the many medications associated with impotence.
Impotence caused by hormones
Hormonal abnormalities such as increased prolactin (a hormone produced by the anterior pituitary gland), steroid abuse by body, too much or too little thyroid hormone, and hormones administered to treat prostate cancer can cause impotence. Rarely is low testosterone responsible for impotence.
