Erectile Dysfunction in Young Men: Causes & Solutions

Erectile dysfunction (ED) in men <40 is increasingly recognized. While prevalence rises with age, ~8–10% of men 20–29 and 11–15% of men 30–39 report ED.

Common Causes in Young Men

• Psychogenic (Most Common): Performance anxiety, depression, stress, relationship issues, pornography-induced conditioning (PIED), body image.
• Lifestyle: Smoking (vascular), excessive alcohol, sedentary, obesity, poor sleep.
• Medications: SSRIs/SNRIs, finasteride, antihypertensives (beta-blockers, thiazides), opioids.
• Medical: Early diabetes/insulin resistance, hypertension, dyslipidemia, hypogonadism (low T), thyroid disorders, pelvic trauma/surgery, Peyronie's.
• Neurologic: MS, epilepsy, spinal cord injury.

Evaluation

1. History: IIEF-5/SHIM questionnaire, sexual/medical/psych/medication/substance history.
2. Physical: Genital exam, vascular (femoral/popliteal/dorsalis pedis pulses), neurologic (bulbocavernosus reflex), secondary sexual characteristics.
3. Labs: Fasting glucose/HbA1c, lipid panel, total/free testosterone (AM), LH/FSH, prolactin, TSH.
4. Specialized: Nocturnal penile tumescence (NPT), penile Doppler ultrasound (vascular).

Treatment

• Psychogenic: CBT, sex therapy, mindfulness, sensate focus, address PIED.
• Lifestyle: Smoking cessation, weight loss, exercise (improves endothelial function), moderate alcohol.
• Oral PDE5 Inhibitors: Sildenafil, tadalafil, vardenafil — first-line pharmacotherapy. High efficacy in psychogenic/vasculogenic ED.
• Testosterone Replacement: Only if confirmed hypogonadism + symptoms.
• Vacuum Erection Device, Intraurethral Alprostadil, Intracavernosal Injections: Second-line.
• Penile Implant: Last resort (refractory).

Key Message: ED in young men is common, treatable, and often a marker of future cardiovascular risk. Seek a urologist or men's health specialist.
