ED has two broad categories of cause: organic (physical) and psychogenic (psychological). Most clinical guidelines recommend determining which category — or which combination — you're dealing with before choosing treatment. This self-assessment can help you organize your thinking before talking to a provider.
The Distinction Matters for Treatment
A man with performance anxiety might respond fully to a few sessions of cognitive behavioral therapy, or to a short course of PDE5 inhibitors to rebuild confidence — then not need medication long-term. A man with progressive vascular disease needs ongoing treatment plus cardiovascular risk management. Treating one like the other wastes time and may miss a serious underlying condition.
Indicators of Psychogenic ED
Psychogenic ED tends to share these characteristics:
- Sudden onset. It appeared abruptly, often associated with a specific event — a new relationship, job stress, relationship conflict, or a traumatic sexual experience.
- Situational. Erections are present during masturbation or with certain partners but absent in other contexts. Morning erections are intact.
- Variable. Some encounters work fine; others don't. The unpredictability itself often worsens anxiety.
- Associated with stress, anxiety, or mood. Onset correlates with a period of high stress, depression, performance pressure, or relationship issues.
- Age under 40. Though psychogenic ED occurs at any age, it's disproportionately common in younger men without cardiovascular risk factors.
Indicators of Organic ED
Organic ED tends to share these characteristics:
- Gradual onset. It developed slowly over months or years, often progressing from intermittent difficulty to consistent inability.
- Global. Erections are affected across all contexts — solo, partnered, and nocturnal. Morning erections are diminished or absent.
- Consistent. The difficulty is present at every encounter, not situational.
- Associated with risk factors. Diabetes, hypertension, smoking, obesity, high cholesterol, or cardiovascular disease are present.
- Medication-related. Onset corresponds with starting a new medication known to affect sexual function (antihypertensives, SSRIs, finasteride, opioids).
- Age over 50. Organic causes become increasingly prevalent with age as vascular disease progresses.
The Self-Assessment Worksheet
Answer these questions honestly. No one sees your answers but you.
The Reality: Most Men Have Both
Pure psychogenic ED and pure organic ED exist, but mixed presentations are the norm, especially in men over 40. A common trajectory: mild vascular changes reduce erectile reliability → failed erections cause performance anxiety → the anxiety further impairs function → a cycle establishes itself.
PDE5 inhibitors can break this cycle regardless of cause. They improve the physical response, which reduces anxiety, which improves subsequent encounters without medication. Some men use PDE5 inhibitors as a "bridge" — restoring confidence, then tapering off.
When to Get the Full Workup
See a provider (urologist or primary care, not just a telehealth prescription platform) if:
- Morning erections have disappeared entirely
- You have diabetes, hypertension, or cardiovascular disease
- ED appeared after starting a new medication
- You're under 30 with no obvious psychological cause
- You have associated symptoms: reduced libido, fatigue, mood changes (suggest hormonal workup)
- You notice penile curvature developing (suggests Peyronie's disease)
A thorough workup typically includes: testosterone level, fasting glucose or HbA1c, lipid panel, thyroid function, and sometimes penile Doppler ultrasound if vascular cause is suspected.
