An erection requires a precise sequence of events, which includes nerve impulses in the brain, spinal column, and area around the penis; and response in muscles, fibrous tissues, blood vessels in and near corpora cavernosa. E.D. can occur when this sequence is disrupted.
Damage to nerves, arteries, smooth muscles, and fibrous tissues as a result of disease is the most common cause of ED. Diseases such as diabetes, kidney disease, chronic alcoholism, multiple sclerosis, atherosclerosis, vascular disease, and neurologic disease account for about 70 % of ED cases. Between 35- 50 % of men with diabetes experience ED. Lifestyle that contribute to heart diseases and vascular problems also raise the risk of ED. Smoking, overweight and avoiding exercise are possible causes of ED.
Also, Pelric surgery (especially radical prostate and bladder surgery for cancer) can injure the nerves and blood vessels, causing ED. Injury to the penis, spinal cord, prostate, bladder, or pelvis can lead to ED by harming the nerves, smooth muscles, arteries, and fibrous tissues of the corpora cavernosa.
In addition, many common medicines likeblood pressure drugs, antihistaminics, antidepressants, tranquilizers, appetite suppressants, and cimetidine ( ulcer drug)can produce ED as a side effect. This account for about 25 % of ED cases.
Psychological factors such as stress, anxiety, guilt, depression, low self-esteem, and fear of sexual failure cause 10-20 % of ED cases. Men with physical cause for ED frequently experience same sort of psychological reactions (stress, anxiety, guilt, depression). Other possible causes are smoking, which affects blood flow in blood vessels, and hormonal abnormalities, such as low testosterone.
Symptoms of Premature Ejaculation
With Erectile Dysfunction (ED), it is hard to get or keep an erection that is firm enough for sex. When ED becomes a routine and bothersome problem, your primary care provider or a Urologist can help.
ED may be a major warning sign of cardiovascular disease indicating blockages are building in a man's vascular system. Some studies have shown men with ED are at significant risk of getting a heart attack, stroke or circulatory problems in the legs. ED also causes:
- Low self-esteem
- Distress for the man and his partner
If ED is affecting a man's well-being or his relationships, it should be treated. Treatment aims to fix or enhance erectile function, help circulatory health and help the quality of a man's life.
- Most physicians suggest that treatments proceed from least to most invasive. For some men, making a few healthy lifestyle changes may solve the problem. Quitting smoking, losing excess weight, and increasing physical activity may help some men regain their sexual function.
- Cutting back on the drugs having harmful side effects is considered the next step. For example, drugs for high blood pressure work in different ways. If you think a particular drug is causing problems with erection, tell your doctor and ask whether you can try a different class of blood pressure medicine.
- Psychotherapy and behavior modifications in selected patients are considered next if indicated.
- followed by oral
- locally injected drugs.
- vaccum devices
- Surgically implanted devices.
- In rare cases, surgery involving blood vessels may be considered.
