What is the appropriate workup for erectile dysfunction in a 67-year-old man?

Workup of Erectile Dysfunction in a 67-Year-Old Man

All men presenting with erectile dysfunction should undergo a comprehensive medical, sexual, and psychosocial history, targeted physical examination, morning serum total testosterone level, and selective laboratory testing including fasting glucose and lipid panel 1.

Essential History Components

The evaluation must systematically address:

• Onset, severity, and degree of bother from symptoms
• Specific erectile pattern: difficulty attaining vs. maintaining erection
• Presence of nocturnal/morning erections (suggests psychogenic component if present)
• Situational factors: partner-specific, context-dependent symptoms
• Prior erectogenic therapy use
• Comorbid conditions: diabetes, hypertension, cardiovascular disease, prior pelvic surgery/radiation, neurological disorders
• Current medications (many antihypertensives and other drugs cause ED)
• Cardiovascular risk factors: smoking, obesity, sedentary lifestyle, family history of MI
• Psychosocial factors: depression, anxiety, relationship conflict 1

The most recent European guidelines 2 emphasize that ED pathophysiology is typically multifactorial, with vasculogenic causes (smoking, obesity, cardiovascular disease, diabetes, metabolic syndrome) being most common in this age group.

Use Validated Questionnaires

Administer the Sexual Health Inventory for Men (SHIM) or Erection Hardness Score to quantify severity, track treatment response, and facilitate discussion 1. This provides objective baseline data and reduces patient discomfort in discussing sexual concerns.

Physical Examination

Focus on:

• Vital signs: pulse and blood pressure (assess cardiovascular status)
• Genital examination:
  • Penile skin lesions, urethral meatus configuration
  • Palpate stretched penis from pubic bone to coronal sulcus for plaques/deformities (Peyronie's disease)
  • Note: palpable plaque doesn't definitively confirm clinically relevant deformity
• Digital rectal exam is NOT required for ED evaluation 1

Laboratory Testing

Mandatory Tests:

• Morning serum total testosterone (hypogonadism defined as <300 ng/dL with symptoms) 1
• Fasting glucose or HbA1c (diabetes screening)
• Lipid panel (cardiovascular risk assessment) 1, 3

Optional/Selective Tests:

• Thyroid-stimulating hormone if clinically indicated 3
• PSA if considering testosterone therapy 2
• Extended hormone panel only if hypogonadism suspected 4

Critical caveat: Most routine serum studies beyond these won't alter ED management 1.

Cardiovascular Risk Assessment

ED is a sentinel marker for cardiovascular disease—as strong a predictor of future cardiac events as smoking or family history of MI 1. The most recent guidelines emphasize this strongly 2, 1.

You must:

• Counsel the patient that ED symptoms typically precede coronary symptoms by ~3 years 3
• Communicate this cardiovascular risk to the patient's primary care provider
• Initiate or optimize cardiovascular risk factor management 1

Specialized Testing (When Indicated)

Reserve for complex cases 1:

• Nocturnal penile tumescence/rigidity testing
• Intracavernosal injection testing
• Penile duplex ultrasound (often combined with intracavernosal injection)
• Cavernosometry
• Selective internal pudendal angiography

These are NOT part of routine workup for a 67-year-old with straightforward ED.

Psychosocial Evaluation

Consider referral to mental health professional for:

• Predominantly psychogenic ED (suggested by preserved nocturnal/morning erections)
• Performance anxiety
• Depression, anxiety, relationship conflict
• Treatment adherence issues
• Integration of ED treatments into sexual relationship 1

This is a moderate-strength recommendation and should be offered as adjunct or alternative to medical treatment 1.

Common Pitfalls to Avoid

1. Don't skip testosterone testing—hypogonadism is treatable and may be first-line therapy for mild ED 2
2. Don't order extensive laboratory panels—they rarely change management 1
3. Don't miss the cardiovascular connection—ED evaluation is an opportunity for cardiovascular risk reduction 1, 3
4. Don't perform DRE routinely—it's not indicated unless evaluating concurrent BPH 1
5. Don't forget to involve the partner in discussions when appropriate 1

The 2025 European guidelines 2 provide the most current framework, emphasizing that in hypogonadal patients with mild ED, testosterone therapy should be first-line treatment, with combination PDE5 inhibitors and testosterone for more severe cases.
