What is Erectile Dysfunction

Any man can have a problem getting or maintaining an erection once in a while. When this happens repeatedly, the problem is known as erectile dysfunction, or simply ED.

It is normal for a man to experience changes in his sexual patterns as he ages. It may take longer for him to develop an erection, his penis may not become as rigid, or it may take more stimulation to bring about an erection. It is not uncommon for older men to have less intense orgasms than they used to, and it may take them longer to recover between erections.

An erection begins with stimulation. This can be a mental image, physical contact, or both. The stimulation causes the brain to send a signal to the muscles in the penis telling them to relax. This permits blood to flow in and fill the spongy interior of the penis, causing it to expand. Once a man has an erection, the muscles contract to stop blood from flowing in. When the blood begins to flow out, the erection reverses. When something happens to disrupt this chain, the result can be ED.

What causes Erectile Dysfunction?
The most common cause of Erectile Dysfunction is damage to nerves, arteries, muscles, and other tissues that may be the result of a health problem such as diabetes, kidney disease, chronic alcoholism, multiple sclerosis, cardiovascular disease, or neuro¬logic disease. An injury to the penis, spinal cord, prostate, bladder, or pelvis can harm nerves, muscles, or arteries and can lead to Erectile Dysfunction.

Erectile Dysfunction may also occur as a side effect of certain medicines, including some blood pressure drugs, antihistamines, antidepressants, tranquilizers, and appetite suppressants.

Psychological factors such as stress, anxiety, guilt, depression, low self-esteem, and fear of sexual failure can also influence a man’s ability to achieve and maintain an erection.

Other possible causes include smoking (which affects blood flow in the veins and arteries), heavy alcohol consumption, and hormonal abnormalities such as low testosterone levels.
