Start Consultation →Breaking the Stigma Around ED
A 2020 European Association of Urology (EAU) survey of over 3,000 men and women across the UK, Spain, France, and Germany found that 34% gave incorrect answers about what ED is, and 17% did not know at all. Of those who had personally experienced ED, 26% had not discussed it with anyone.
This silence tends to make the problem worse. Stress, shame, and avoidance compound both the psychological and relationship dimensions of ED. Speaking to a partner, a friend, or a healthcare professional is often the first meaningful step toward improvement.
Why Does ED Happen?
Physical Causes
- Cardiovascular disease and high blood pressure — reduced blood flow throughout the body, including to the penis
- Diabetes — causes both nerve damage (diabetic neuropathy) and blood vessel damage
- Obesity — raises cardiovascular risk, impairs hormone balance, worsens vascular function
- Hormonal imbalances — low testosterone (hypogonadism), thyroid disorders
- Neurological conditions — Parkinson’s disease, multiple sclerosis, spinal cord injury
- Surgery — particularly radical prostatectomy; see our guide to surgery and erectile dysfunction
Psychological Causes
- Performance anxiety — the most common psychological cause; one difficult experience creates a self-reinforcing negative cycle
- Depression — reduces libido and disrupts the neurological pathways for sexual arousal
- Stress and fatigue — chronic stress suppresses testosterone and interferes with sexual function
- Relationship problems — communication difficulties, conflict, or reduced emotional intimacy
Psychological and physical causes often interact. A man with a physical vascular problem may develop performance anxiety, which compounds the original issue.
Medication-Related Causes
Many commonly prescribed medications can contribute to ED, including beta-blockers, certain antidepressants (SSRIs), diuretics, and anti-androgens. If you believe a medication is contributing, discuss alternatives with your prescriber — do not stop any medication without medical guidance. For a full breakdown, see what causes erectile dysfunction.
Diagnosing Erectile Dysfunction
ED is a clinical concern when it occurs more than half the time during attempted sexual activity, has been present consistently for more than 2–4 weeks, or causes significant distress. Occasional difficulty — particularly after alcohol, stress, or fatigue — is entirely normal and is not ED.
A prescriber or GP will take a full medical history including ED symptoms, cardiovascular risk factors, medications, and lifestyle factors. Blood tests may include testosterone, blood glucose, lipid profile, and thyroid function.
Treatment Options — Full Overview
First-Line: Oral PDE5 Inhibitors
NICE recommends offering a PDE5 inhibitor as first-line pharmacological treatment for ED. Sexual stimulation is required with all four.
| Medication | Active ingredient | Duration | Key advantage |
|---|---|---|---|
| Sildenafil (Viagra) | Sildenafil | 4–6 hours | Most widely known; generic available; ~82% success |
| Tadalafil (Cialis) | Tadalafil | Up to 36 hours | Longest duration; daily option (5mg); ~81% success |
| Vardenafil (Levitra) | Vardenafil | 4–6 hours | May work slightly faster in some men; ~80% success |
| Avanafil (Spedra) | Avanafil | Up to 6 hours | Fastest onset (~15–30 minutes); ~77% success |
Critical safety: PDE5 inhibitors must not be taken with nitrate medicines (glyceryl trinitrate, isosorbide mononitrate) due to the risk of a severe, potentially fatal blood pressure drop. A prescriber assessment screens for this and other contraindications.
Second-Line Options
- Lifestyle changes — weight loss, exercise, quitting smoking, reducing alcohol; see lifestyle changes for ED
- Psychological therapy — CBT, sex therapy and couples counselling are effective for psychologically-driven ED
- Vacuum erection device (VED) — effective in ~75% of men; no drug interactions or systemic effects
- Alprostadil injection — bypasses the nitric oxide pathway; ~85% success rate in diabetic men
- Penile implants — satisfaction rates of 90–95% in appropriately selected patients; typically considered after other options are exhausted
Talking to a Partner About ED
Clinical evidence supports open communication as one of the most important factors in successful ED management. Relationship strain caused by ED rarely resolves on its own. Clinical psychologists recommend choosing a calm moment away from the bedroom, being honest about what is happening physically and emotionally, asking how your partner is feeling, and considering couples counselling if direct conversation is difficult.

Frequently Asked Questions
What is the most effective treatment for erectile dysfunction?
NICE recommends oral PDE5 inhibitors — sildenafil, tadalafil, vardenafil, or avanafil — as first-line treatment. All four have success rates of 77–82%. The best option depends on preferences regarding duration, food interactions, and daily vs on-demand use.
Can erectile dysfunction be treated without medication?
Yes — particularly for men with lifestyle-related or psychologically-driven ED. Weight loss, regular exercise, quitting smoking, reducing alcohol, and psychological therapy can all improve or resolve ED without medication.
Is ED treatment available on the NHS?
Yes, under specific criteria. Access Doctor provides the same prescription treatments via a private online consultation without a GP referral, usually with same-day or next-day delivery.
How do I talk to my partner about erectile dysfunction?
Choose a calm moment away from the bedroom, be honest about what is happening physically and emotionally, and ask how your partner is feeling. Communication is one of the most important factors in successful ED management.
Is erectile dysfunction permanent?
No — for most men, ED is treatable and often reversible, particularly when an underlying cause is identified and addressed. Oral PDE5 inhibitors are highly effective for most men.
