Erectile dysfunction is the inability to get or keep an erection during sexual activity. It varies in severity, some men may be totally unable to achieve an erection while others may achieve an erection inconsistently, and others may only have the ability to sustain brief erections. Although, the condition is under-diagnosed, it is estimated that a vast number is affected.

While ED can occur at any age,Guest Posting it is not often found in young men, elderly males are more affected by this condition. By the age of 45, most men have experienced ED at some point in their lives.

Erection begins with sexual stimulation. Sexual stimulation can be either tactile or mental or both. Being sexually stimulated generates electrical impulses along the nerves going to the penis and causes the release of nitric oxide, which in turn increases the production of cyclic GMP (cGMP) in the smooth muscle cells of the corpora cavernosa. The cGMP causes the smooth muscles to relax and allows for rapid blood flow into the penis. The in-coming blood fills the corpora cavernosa, making the penis engorged and thereby sustaining an erection. Erection is reversed when the cGMP levels fall, causing the smooth muscles to contract, stopping the inflow of blood and opening the veins that drain the blood away from the penis. In turn, the cGMP levels also drop because it is then destroyed by the PDE5 enzyme.

What are the causes of Erectile Dysfunction?

The causes of erectile dysfunction can be manifold but the ability to achieve and sustain an erection requires:

  • A healthy nervous system that conducts nerve impulses in the brain, spinal column and the penis

  • Healthy arteries in and around the corpora cavernosa

  • Healthy smooth muscles and fibrous tissues within the corpora cavernosa

  • Adequate levels of nitric oxide in the penis

Erectile dysfunction can occur if one or more of these requirements are not met. The causes of erectile dysfunction include:

Aging: Older men are more likely to experience erectile dysfunction because they are most likely to develop diseases like heart attacks, angina, strokes, diabetes mellitus, and high blood pressure that can have a direct bearing on erectile function. Sometimes, the aging process itself can cause ED; this happens because the compliance of the tissues reduces. In addition, the decreased production of nitric oxide in the nerves could innervate the corporal smooth muscles within the penis.

Diabetes mellitus: Diabetic men are more prone to ED. The increased risk of erectile dysfunction among these men may be due to the earlier onset and greater severity of atherosclerosis that narrows the arteries and thereby reduces the delivery of blood to the penis. When the penis receives insufficient blood, achieving an erection becomes difficult.

In addition, diabetes mellitus can cause diabetic neuropathy, resulting in ED. Moreover, smoking cigarettes, obesity, poor control of blood glucose levels, and having diabetes mellitus for a long time further increases the risk of ED. Furthermore, because of atherosclerosis many diabetics can develop muscle disease where compliance of the muscle in the corpora cavernosa is hampered and this clinically presents an inability to maintain an erection.

Hypertension (high blood pressure): Patients with hypertension or arteriosclerosis have an increased risk of developing ED. Patients with hypertension have been found to have a low production of nitric oxide by the arteries of the body, including the penis. Decreased levels of nitric oxide will contribute to erectile dysfunction.

Cardiovascular diseases: Atherosclerosis is the most common cause of cardiovascular diseases, where the arteries narrow and harden to an extent that the blood flow is reduced. Hypertension, high blood cholesterol levels, cigarette smoking and diabetes mellitus aggravate atherosclerosis. When coronary arteries are narrowed by atherosclerosis, heart attacks and angina can occur. When cerebral arteries are narrowed, strokes can also occur. Similarly, when arteries to the penis and the pelvic organs are narrowed, ED often occurs. In fact, some doctors believe that men with recent onset of ED should be evaluated for silent coronary artery diseases.

Cigarette smoking: Smoking also aggravates atherosclerosis which significantly increases the risk for ED.

Nerve or spinal cord damage: Damage to the spinal cord and nerves in the pelvic region can cause ED. Nerve damage can be due to disease like multiple sclerosis, accident trauma, surgical procedures like prostate surgery and long-term diabetes mellitus.

Substance abuse: Marijuana, heroin, cocaine, and alcohol abuse can also contribute to ED in a big away. In addition to causing nerve damage, substance abuse can lead to atrophy of the testicles and lower testosterone levels.

Low testosterone levels: Testosterone (the primary sex hormone in men) is essential for sex drive (libido). In addition, it helps maintain nitric oxide levels in the penis.

Medications: Many commonly used medicines cause erectile dysfunction as a side effect. Antihistamines, antidepressants, tranquilizers, and appetite suppressants can cause ED.

Depression and anxiety: Psychological factors like stress, anxiety, guilt, depression, low self-esteem and fear of sexual failure may be responsible for erectile dysfunction.

Viagra as an effective impotence medication

Viagra can certainly help to treat ED. It increases the levels of nitric oxide, a chemical that is produced by the body during sexual stimulation. This chemical enhances the amount of cGMP that in turn causes the blood vessels in the penis to relax and open. These medications don’t automatically trigger an erection; but in combination with sexual arousal it helps kick-start the whole process.

Sexual arousal stimulates the release of a compound called nitric oxide (NO) in the penis. Nitric oxide, in turn, triggers the synthesis of cGMP, which relaxes the smooth muscle tissue in the penis, and allows extra blood to flow into the organ’s spongy central erectile tissues. Viagra enhances this smooth muscle relaxation, spurring greater blood flow into the penis.
