Erectile dysfunction

Erectile dysfunction: Introduction

Erectile dysfunction is the inability of a man to achieve or maintain an erection that is sufficient to complete sexual intercourse. Erectile dysfunction, also referred to as ED or impotence, is a common condition that may temporarily affect most men at some time in their lives. If the condition is short-lived and does not recur frequently, it is generally considered normal. If erectile persists, it can result in complications, such as male infertility and mental health issues, such as anxiety and depression.

Achieving and maintaining an erection is a complex process that involves a complex interplay of psychological elements as well as processes of the nervous system and the circulatory system. In a normal erection, sexual stimulation or arousal triggers nerves to increase the blood flow in the penis. This extra blood flows in the corpus cavernosum of the penis. The corpus cavernosum are spongy structures that absorb the blood and expand, causing the penis to enlarge, strengthen, and become hard. Normally, the penis will maintain the erection until after ejaculation or when sexual excitement has ended.

There are various conditions that can affect one or more of these elements or processes and result in erectile dysfunction. These include having certain diseases that impede normal circulation to the penis, such as diabetes, atherosclerosis, alcoholism, kidney disease, and multiple sclerosis. Conditions that can interfere with normal nerve impulse transmission to the penis include neurologic disease and some types of spinal cord trauma. Psychological causes, such as depression, anxiety, guilt, and low self esteem, can also result in or aggravate erectile dysfunction.

Other causes of erectile dysfunction include obesity, testicular trauma, and some surgical procedures, such as those for prostate or bladder cancer. Certain medications, such as some high blood pressure medications, may also cause erectile dysfunction in some men.

The primary symptom of erectile dysfunction is an inability to achieve or maintain an erection sufficient to complete sexual intercourse at least 25 percent of the time. For more information on symptoms, refer to symptoms of erectile dysfunction.

Making a diagnosis of erectile dysfunction begins with taking a thorough personal and family medical history, including symptoms, and completing a physical examination and neurological evaluation. It also includes performing blood and urine tests and other tests that check blood flow to the penis. These tests help diagnosis the cause and/or any other conditions, such as diabetes, that may underlie erectile dysfunction.

A diagnosis of erectile dysfunction can easily be missed or delayed due to a variety of factors. For more details on misdiagnosis, refer to misdiagnosis of erectile dysfunction.

Treatment of erectile dysfunction varies depending on the specific cause of the condition, a patient's goals, and the individual case. Treatment may include medications, the use of special devices, psychotherapy and sex therapy, addressing underlying causes of the condition, and/or surgery.
