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.

Diabetes is one of the most common diseases worldwide. Diabetes causes ED very often: men with diabetes are three times more likely to have problems with potency than men who do not suffer from this disorder.

The risk of developing ED increases if you suffer from diabetes for a long time and if your blood sugar levels are high.

Though practically all men with diabetes have problems with erections, these problems can be successfully solved by proper treatment.
Diabetes has a negative impact on a peripheral nerve function which is associated with bad peripheral blood flow. Bad blood inflow into penis results in inability to have or maintain normal erections in men.
Diabetes often causes damage to the nerves of the penis. This damage negates male’s ability to have erections.

In case blood sugar level is constantly high or over the normal level the nitric oxide (NO) necessary for normal erection process is not produced in enough amounts.  That is why high blood sugar level prevents natural erection process to occur.

To make the impact of the disease less negative, you can stop smoking, make more physical exercises and control your blood sugar level regularly. Special diet and medical therapy can also help to avoid developing of ED.

Erectile dysfunction (ED), in other words, the lack of potency, which can be characterized as inability to achieve or sustain an erection for satisfactory sexual activity. ED  stays apart from other conditions that interfere with male sexual intercourse, such as lack of sexual desire and problems with ejaculation and achieving orgasm.

Erectile dysfunction can have different forms: it can be mild, moderate or severe. The last form is when men have a total inability to achieve an erection. People with moderate ED have an inconsistent ability to achieve an erection. Mild form of ED is the easiest to treat and can be associated with taking certain medications or having conditions interfering with normal erectile process.

Estimating ED frequency is extremely difficult and hardly possible to find out the real number of men suffering from this disorder.  The reason is that men fear to discuss erectile dysfunction with their doctors due to embarrassment. That is why experts can’t say for sure how many men erectile dysfunction affects.

ED problems can occur at any age, but it is uncommon among young men (younger than 40) and more common in the elderly. With age most men experience problems with potency more often.

According to recent study which associated ED with aging, ED increases from 5% among men 40 years of age to 15% among men 70 years and older. Erectile dysfunction occurs in 20% of men between ages 50-54, and in 50% of men between ages 70-78. As for the severity of ED, studies have noted that 35% of men 40-70 years of age suffer from moderate to severe ED, and an additional 15% may have milder forms.

Erection occurs naturally when a male is sexually excited or has sexual desire. The erection process is quick filling of the penis with more blood than usual. The penis tissues expand and the penis becomes hard or erected.

After the climax of sexual activity when orgasm is achieved, the extra blood flows out of the penis back into the body. The erection process naturally stops.

If an erection lasts for a long time (more than 4- 6 hours), it is not natural and is called priapism. This condition can permanently damage the penis. A person who experiences this condition should call a doctor immediately.  If a person ever has a prolonged erection that lasts more than 4 hours it should be carefully considered whether he could take Viagra.

Some health conditions and medications interfere with the natural erection process. There is not enough blood inflow in penis for maintaining good erections. The man who of cannot have erections face the problem called erectile dysfunction.
