What Is ED? Causes, Symptoms & Treatment Options Explained [Physician-Supervised]

ED

Erectile dysfunction (ED) is a medical condition that many men experience. Although it can be improved with appropriate treatment, many men still struggle with it alone. This article explains the definition, causes, and treatment options for ED in a clear, physician-supervised manner.

What is ED? Start by understanding it correctly

Erectile dysfunction (ED) is defined as “the persistent or recurrent inability to achieve or maintain an erection sufficient for satisfactory sexual performance.”

It was once called “impotence,” but today the medical term “ED” is widely used. This change reflects a shift in understanding—that it is a condition to be addressed properly as a medical issue.

Symptoms of ED

The symptoms of ED vary from person to person. If any of the following occurs on a “persistent or recurrent” basis, ED may be diagnosed.

• No erection occurs at all (complete ED)
• An erection occurs but is not firm enough for penetration
• An erection occurs but is lost partway through
• No erection only in specific situations (during intercourse with a partner)
• No problem during masturbation, but no erection during intercourse

Temporary cases, or those limited to times of fatigue or alcohol consumption, are different from ED. If symptoms that concern you persist, we recommend consulting a specialist early.

Causes of ED: three categories

Organic ED (physical causes)

This is ED caused by physical problems such as those of the blood vessels, nerves, or hormones. It tends to be more common from the 40s onward.

• Vasculogenic: impaired blood flow due to arteriosclerosis, hypertension, diabetes, and the like. The most common type.
• Neurogenic: nerve damage from spinal cord injury, post-prostate-surgery, and similar causes
• Endocrine: a decline in the male hormone testosterone
• Drug-induced: side effects of antihypertensives, antidepressants, treatments for benign prostatic hyperplasia, and other medications

Psychogenic ED (mental/psychological causes)

This is ED caused by mental or psychological stress. It tends to be more common among younger people. A characteristic feature is “an erection occurs during masturbation but not during intercourse with a partner.”

• Performance anxiety (the pressure of “will I be able to do well?”)
• Depression and anxiety disorders
• Relationship problems with a partner
• Dependence on pornography (PIED: porn-induced ED)

Mixed ED

This is a case in which both organic and psychogenic factors are intertwined. Once a physical problem triggers ED, the anxiety of “I might fail again” often adds a psychogenic component, leading to a vicious cycle.

“ED at a young age?” is not uncommon

ED is often pictured as a problem for middle-aged and older men, but it is also commonly seen in men in their 20s and 30s.

In recent years, the rise of pornography dependence (PIED) driven by the spread of smartphones and PCs has also been a factor behind ED in younger men. Rather than thinking “I’m still young, so I’m fine,” it is important to seek advice early once you notice something.

Treatment options for ED

PDE5 inhibitors (oral medication)

This is the drug therapy at the center of current ED treatment. These medications support an erection when sexual stimulation is present, and they do not work without sexual stimulation.

Low-intensity extracorporeal shockwave therapy (LI-ESWT)

This treatment applies low-intensity shockwaves to the penis to promote the formation of new blood vessels. It aims to improve erectile function at its root without relying on medication. It is especially expected to be effective for vasculogenic ED.

Testosterone replacement therapy

When a decline in the male hormone testosterone is the cause, replacement therapy can be effective. It is available in forms such as injections, gels, and patches.

Psychotherapy and counseling

For psychogenic ED, a psychological approach—not just medication—is effective. Cognitive behavioral therapy, and couples counseling attended together with a partner, are also options.

What to know before your visit

ED may be a warning sign of lifestyle-related disease

ED may be an early warning sign of lifestyle-related diseases such as cardiovascular disease, diabetes, and hypertension. Because the blood vessels of the penis are among the thinnest in the body, they are a site where the effects of arteriosclerosis tend to appear first.

Some research reports that “men who develop ED are at higher risk of developing heart disease within the following 3 to 5 years.” Rather than regarding ED merely as a “sexual function problem,” it is important to treat it as an opportunity to review your overall health.

Summary

“It’s just age, so it can’t be helped,” “I’m too embarrassed to ask”—many men feel this way and carry the burden alone, but with appropriate treatment, improvement can be expected in many cases. Once something concerns you, start by consulting a specialist physician.
