Erectile dysfunction (ED) is the consistent inability to achieve or maintain an erection firm enough for satisfying sex. Occasional difficulty is normal and not a cause for concern, but persistent ED is common - it affects tens of millions of American men - and it is very treatable. Just as important, ED can be an early warning sign of blood-vessel disease, so it deserves a real medical evaluation rather than silence. The likelihood of ED rises with age, but at no age is it something a man simply has to accept. Causes: An erection depends on healthy blood flow, nerves, hormones, and mood, so problems in any of these areas can contribute:

Vascular disease: Narrowed arteries from atherosclerosis - the same process behind coronary artery disease and peripheral arterial disease - is the most common physical cause. ED can appear years before heart symptoms do.
Diabetes: Long-standing diabetes damages both the small blood vessels and the nerves involved in erections.
Hormonal problems: Low testosterone and thyroid disorders can reduce desire and performance.
Medications: Some blood pressure medicines, antidepressants, and prostate treatments list ED as a side effect. Never stop a medication on your own - ask your physician about alternatives.
Psychological factors: Stress, performance anxiety, relationship strain, and depression can cause or worsen ED, and often coexist with physical causes.
Lifestyle: Smoking, heavy alcohol use, inactivity, and excess weight all impair blood-vessel health.

Symptoms: The pattern of symptoms offers useful clues. Gradually worsening erections over months to years point toward a vascular or metabolic cause, while sudden-onset ED - especially when morning erections are preserved - suggests a psychological contributor. Reduced sexual desire alongside fatigue may point toward low testosterone. If symptoms have persisted more than a few months, or are straining your confidence or relationship, that is reason enough to be evaluated. Diagnosis: Evaluation starts with a straightforward, confidential conversation and a physical exam. Blood tests commonly check morning testosterone, blood sugar, and cholesterol, since ED is frequently the first clue to undiagnosed diabetes or lipid problems. Because ED and heart disease share the same root causes, your physician will also assess your overall cardiovascular risk, review your blood pressure, and go through your full medication list for common, correctable contributors. Treatment: Most men can be treated successfully:

Oral medications: Phosphodiesterase-5 (PDE5) inhibitors such as sildenafil and tadalafil improve blood flow to the penis and work for most men. Sildenafil is taken as needed before sexual activity, while tadalafil is longer acting; your physician will match the choice to your health and preferences. They must never be combined with nitrate heart medications, which can cause a dangerous drop in blood pressure.
Treating the underlying cause: Better control of blood sugar, blood pressure, and cholesterol - plus quitting smoking and regular exercise - improves erections and protects the heart at the same time. Even modest weight loss and a consistent walking habit measurably improve vascular health.
Counseling: When anxiety or depression contributes, therapy alone or combined with medication is often effective.
Other options: Vacuum erection devices, penile injections, and surgical implants are available through urology when pills are not enough.

ED is a medical issue, not a personal failing, and discussing it can uncover conditions well worth treating early - most men are surprised how straightforward the evaluation is.
