The causes of erectile dysfunction are divided into 2 main groups: physical and psychological. Read this information about ED afflictions carefully, if necessary ask your doctor for more information.

The following are the physical causes of erectile dysfunction:

Aging – is without doubt a reason why men experience problems with getting and maintaining erections. This happens due to medical health conditions that develop in men with age. Older men suffer from heart attacks, angina, cardiovascular disease, strokes, diabetes, and high blood pressure. Besides, the aging process can cause erectile dysfunction in some men, primarily by less production of nitric oxide in the nerves that involves in the mechanism of natural erection.

Diabetes is the second main reasons why males over 45-50 years are more vulnerable to erectile dysfunction. ED is more likely to develop 10-15 years earlier in diabetic men than among those who do not suffer from this disorder.

Hypertension (high blood pressure) increases the risk of developing ED because of its close connection with such medical condition as arteriosclerosis which accompanies hypertension.

Cardiovascular disease is also associated with atherosclerosis in the coronary arteries and thus with developing of erectile dysfunction.

Cigarette smoking and alcohol in large amounts aggravate atherosclerosis and thereby increases the risk for erectile dysfunction.

Very often the damage caused to the spinal cord and nerves in the pelvis can cause erectile dysfunction. Nerve damage can be afflicted by disease, trauma, or surgical procedures.

The usage of certain medications and constant abuse of illegal drugs can contribute to development of potency problems.

The risk factors for developing ED can include the following:

• Age over 60;
• Cardiovascular disease (heart disease);
• Diabetes;
• High cholesterol;
• Smoking;
• Drinking large amounts of alcohol;
• Using of recreational drugs;
• Stress, depression, other psychiatric diseases.

A man to get and sustain erections needs:

1.     A healthy nervous system that conducts nerve impulses in the brain and penis.

2.     Healthy arteries.

3.     Healthy smooth muscles and fibrous tissues.

4.     The necessary amount of nitric oxide in the penis.

If any of these necessary things goes wrong or does not work properly, an erection will not occur.

To have a normal erection you should be sexually aroused. Erection happens with sexual stimulation. Sexual stimulation can be tactile or mental. Sexual stimulation is necessary that is why sexual foreplay may be helpful for those men who have problems with erections.

When you are sexually aroused, electrical impulses are produced by brain and along the nerves go to the penis and this makes the nerves to release nitric oxide. Nitric oxide enlarges the production of cyclic GMP in the smooth muscle cells of the corpora cavernosa. The cGMP makes the smooth muscles of the corpora cavernosa to relax and allow rapid blood flow into the penis. The incoming blood fills the penis and it expands.
