Approach to Erectile Dysfunction

Initial Evaluation

• The American College of Physicians recommends beginning with a comprehensive sexual, medical, and psychosocial history, followed by a focused physical examination and targeted laboratory testing to identify both organic causes and psychogenic factors 1
• The onset pattern of erectile dysfunction suggests psychogenic causes if sudden, while gradual onset indicates organic etiology, according to the British Medical Journal 2, 1
• The International Index of Erectile Function (IIEF) or Sexual Health Inventory for Men can be used to objectively quantify the severity of erectile dysfunction, as suggested by Praxis Medical Insights 1, 3
• Cardiovascular risk factors such as hypertension, atherosclerosis, hyperlipidemia, diabetes mellitus, smoking, and family history of vascular disease should be identified, as noted in The Journal of Urology 4, 1
• Neurological conditions like prior pelvic/perineal trauma or surgery, spinal cord injury, and neurologic disease should be assessed, according to The Journal of Urology 4
• The American Urological Association suggests evaluating endocrine disorders, including signs or symptoms of hypogonadism and obesity 1
• A medication review should be conducted to identify potential contributors to erectile dysfunction, such as antihypertensives, antidepressants, tranquilizers, and recreational drugs, as recommended by the British Medical Journal 2, 1
• The psychosocial assessment must evaluate relationship factors, including partner's sexual function, relationship quality, and presence of major life events, according to the British Medical Journal 2, 1
• Psychiatric conditions like depression, generalized anxiety, alcoholism, and body dysmorphic disorder should be considered, as suggested by the British Medical Journal 2

Physical Examination and Laboratory Testing

• The American Urological Association recommends performing a focused examination, including vital signs, genital examination, and assessment of secondary sexual characteristics, as noted in The Journal of Urology 4, 1
• Essential laboratory tests for all patients include morning serum total testosterone, fasting glucose or HbA1c, and lipid profile, as suggested by Praxis Medical Insights 1, 3
• Additional testing, such as free testosterone or androgen index, prostate-specific antigen, and digital rectal examination, may be necessary in select patients, according to the British Medical Journal 2, 3

Treatment Framework

• The European Association of Urology suggests that erectile dysfunction is a sentinel marker for cardiovascular disease and warrants comprehensive cardiovascular risk assessment, as noted in Praxis Medical Insights 1, 3
• The treatment algorithm should include addressing modifiable factors, such as lifestyle modifications and optimization of comorbid conditions, as recommended by the British Medical Journal 2
• Oral phosphodiesterase-5 inhibitors are the first-line treatment for most patients with erectile dysfunction, according to The Journal of Urology 4
• The American Urological Association recommends considering second-line therapy, including intracavernosal alprostadil injection and vacuum constriction devices, for patients who fail or cannot tolerate phosphodiesterase-5 inhibitors, as noted in The Journal of Urology 4
• Psychosexual counseling should be combined with pharmacotherapy for optimal outcomes, as most erectile dysfunction is multifactorial, according to the British Medical Journal 2
• Specialist referral to urology or andrology may be necessary for certain patients, such as young patients with lifelong erectile dysfunction or those with a history of pelvic trauma, as suggested by the British Medical Journal 2, 4
• Testosterone replacement therapy should only be initiated in men with documented hypogonadism, as recommended by Praxis Medical Insights 3
