Male Impotence Cause Impotence is defined as the inability to achieve or maintain an erection sufficient for mutually satisfying intercourse. Per the diagram adjacent diagram one can see that the incidence of impotence correlates with an individuals age effects some 67% of men by the age of 70 years old. Impotence impacts more than a man's sexual activity. The emotions and uncertainties that coincide with this condition often have a significant effect on a man's self-esteem, as well as, his relationship with his partner.  Although the incidence of Impotence increases with age, it is not an inevitable result of aging.  Impotence is a secondary condition linked to many medical conditions. The first step in treating Impotence is that the individual understands the psychology, physiology and anatomy responsible for the ability to achieve and maintain an erection.  If we can comprehend these events than we can better understand the factors that are responsible for impotence and address the questions concerning treatment.      Normal Erectile Function For something that appears so natural, an erection is a rather complicated process involving the coordination of the psychological, neurological and cardiovascular systems.  The penis becomes erect following a series of events.  First, the nerves are stimulated, a sensation known as arousal.  No matter what the nature of the stimulus, visual, mental or physical the brain coordinates the following series of events: Nerve impulses transverse the length of the spinal cord to the pudendal nerve and on to the penis.  Smooth muscle within the walls of the penile arteries respond by relaxing.   Subsequently, the penile arteries dilate allowing up to eight times more blood to flow into the corpora cavernosum, (two parallel cylinders that transverse the length of the penis).   The cavernosum become engorged with blood expanding and lengthening the penis.   The expanding tissue then exerts a positive pressure compressing the veins that normally empty the blood from the penis, maintaining the blood in the penile tissue.   When ejaculation occurs or when arousal is discontinued the penis returns to its non-erect state.

Causes of Impotence Historically, when an individual consulted his physician concerning impotence he was usually informed there were no known physiological answers concerning his condition.  Today, a generation of research has resulted in significant advances in both the diagnosis and treatment of impotence. Physicians now understand that approximately eighty-five percent of impotence is attributable to physical/organic conditions while only fifteen percent is due to psychological or mixed origin (both psychological and organic).  Some important causes of physiological male impotence are as follows:

Vascular Disease Vascular Disease - is the leading cause of impotence. Vascular disorders including arteriosclerosis (hardening of the arteries), hypertension, hyper-cholestremia and other conditions which interfere with the blood flow to the penis.  Additionally, "venous leakage" also contributes to poor erections.  This condition occurs when the penile veins are unable to constrict efficiently during an erection.  When these veins "leak" blood escapes to the periphery resulting in a poor erection.

Diabetes - is another common cause of impotence. Approximately fifty percent of men with diabetes (insulin dependent) experience some degree of ED after the age of fifty-five.  Diabetes results in poor circulation and/or peripheral neuropathy.  When the nerves are involved sexual stimuli are not transmitted appropriately to or from the brain and Impotence develops.

Neurological diseases - such as multiple sclerosis, Parkinson's disease, spinal cord injuries, long term effects of diabetes can also result in the disruption of the normal sequence of events necessary for an erection to occur.

Deficiencies in the Endocrine System - are another source of impotence. Low levels of testosterone or thyroid hormone can interfere with the stimulation process necessary in the erection sequence.  Excessive production of prolactin by the pituitary gland may contribute to decreased levels of testosterone resulting in a lack of desire.  Diabetes once again enters the scenario as it is classified as an endocrine disorder.

Prescription medications often cause impotence as a side effect.  Some two hundred known medications fall into this category including: Antihypertensives medications significantly: beta-blockers e.g. Atenolol, Propanolol and Tenorium.   Diuretics medications e.g. HydroDiuril and Lasix.   Ace Inhibitors/Calcium Channel Blockers medications e.g. Vasotec®, Lotension®, Cardizem®, Norvasc® periodically cause Impotence , however, they are generally represent an excellent alternative medication for individuals with drug induced impotence. Antidepressant/Antipsychotic medications -of almost any label can also result in Impotence e.g. Prozac®, Elavil®, Zoloft®, Thorazine®, Haldol®. Note: Many other medications in a variety of classes can periodically cause ED.  If you are taking a prescription medication or over-the-counter medication, regularly, please consult with your physician.  However, never alter a dosage or discontinue a medication without the advice of your physician.

Smoking as a Cause of Impotence Smoking as been linked to Impotence in numerous clinical studies. The most common causes of the organic component in Impotence or impotence are vascular abnormalities associated with atherosclerosis and diabetes mellitus. Atherosclerosis causes 40% of cases of Impotence, and in cases of diabetes mellitus the prevalence of Impotence is 50%. Smoking is significantly associated with the development of both atherosclerosis and diabetes mellitus. The Epidemiology and Pathophysiology of Impotence. The Journal of Urology 1999 Jan; 161(1):5-11 After smoking two cigarettes, the diameter of the internal pudendal artery narrows and the penile arteries almost completely close. This evidence suggests that smoking can cause an acute vasospastic constriction of the arteries in the penis. These observations are supported by physiological evidence that nicotine causes acute peripheral vasoconstriction. Acute Vasospasm of Penile Arteries in Response to Cigarette Smoking. Urology 1990; 36(1):99-100 Researchers at Wake Forest University in Winston Salem, North Carolina concluded that men who suffer from long standing hypertension who smoked were 26 times more likely to be impotent than those individuals who do not smoke. The Journal of Family Practice. January 2000, Aside from impotence, smoking as also been linked to the following negative effect concerning male sexual health: Reduced volume of ejaculate   Lowered sperm count   Abnormal sperm shape   Impaired sperm motility Stop the leading causes of impotence, (Buy Cialis impotence treatment drug online click here for details)

LH-RH Analogs/Antiandrogen medications e.g. Lupron Depot®, Eulexin®, Nilandron®, Casodex®, etc.  These medications are used in the treatment of prostate cancer.  They function by decreasing the production of testosterone in the testes and adrennal glands.  The decrease in testosterone often results in Impotence.

Chemotherapy/Radiation -therapy are also significant contributors to Impotence.  These drugs/treatments are used in the treatment of cancer.

Substance Abuse can also negatively effect male potency.  The chronic use of cocaine, marijuana, alcohol, steroids etc. often results in Impotence, as well as a decrease in desire.  Excessive tobacco use can also attribute to Impotence by accentuating the effects of other risk factor such as vascular disease or hypertension.

Radical Pelvic Surgery also result in Impotence. Surgical procedures involving the prostate gland, bladder or colon may interfere with the nerves involved in the erectile response.  Radiation therapy for cancer may also effect the erectile process.

Psychological ED is usually diagnosed when no physical causes can be defined.  Pure psychological Impotence usually occurs suddenly without warning as opposed to physical ED that may gradually develop over years.   Some common causes of psychological Impotence are as follows: Performance anxiety is one of the most common causes of psychological Impotence.  When a man feels pressured to achieve or maintain an erection, he will commonly become anxious and nervous when in a sexually demanding situation.  Stress increases the body's production of catecholamines such as adrenaline and nor- adrenaline, which act as erection inhibitors.  The release of these inhibitors further contributes to failure resulting in more anxiety.  Therefore, the cycle begins, increased stress resulting in increased catecholomines that further inhibits the erectile process.   Depression is another cause of psychogenic Impotence.  Unfortunately, many of the popular antidepressant medications (for a list see prescription medications in the next section) have side effects which include erectile failure.

Anatomical Deviation of the Penis, Peyronie's Disease, may also cause Impotence .  This condition usually develops from an inflammatory process and results in fibrous scaring of the penis.  (The cause of this process is not yet understood)  However, when an erection does occur, there is a bending of the penis secondary to the scar tissue.  This curvature may interfere with erectile capacity and/or ejaculation.
