Erectile dysfunction (ED) in men under 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 concerns.
- Lifestyle: Smoking (vascular), excessive alcohol, sedentary habits, 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 disease.
- Neurologic: Multiple sclerosis, epilepsy, spinal cord injury.
Evaluation
- History: IIEF-5/SHIM questionnaire, sexual/medical/psych/medication/substance history.
- Physical: Genital exam, vascular (femoral/popliteal/dorsalis pedis pulses), neurologic (bulbocavernosus reflex), secondary sexual characteristics.
- Labs: Fasting glucose/HbA1c, lipid panel, total/free testosterone (morning), LH/FSH, prolactin, TSH.
- Specialized: Nocturnal penile tumescence (NPT), penile Doppler ultrasound (vascular assessment).
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.
- Second-line: Vacuum erection device, intraurethral alprostadil, intracavernosal injections.
- Penile Implant: Last resort (refractory cases).
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.
