Erectile dysfunction treatment in London
An erectile dysfunction assessment at Medical Express Clinic is a confidential GP appointment that looks for a medical cause and discusses first-line tablets when they are appropriate.
Erectile difficulty is assessed as a medical concern: the GP asks what has changed, what else is happening and which treatment would be safe.
At the erectile dysfunction assessment, the GP reviews your symptoms, medical history, current medicines and cardiovascular risk, with an examination only when it would change the plan.
A GP erectile dysfunction assessment starts from £150, and blood tests and pharmacy charges are separate when they are used.
When clinically appropriate, the GP may prescribe sildenafil or tadalafil after checking that neither would be unsafe with your current medicines, including nitrates.
If tablets are unsuitable or do not work, the GP can arrange further tests and refer you to an appropriate specialist.
Erectile dysfunction assessments take place at 117a Harley Street, London, with no referral needed; send an enquiry through the form or call 0207 499 1991.
Your appointment options
What the GP reviews
The GP first reviews the problem so that any treatment is based on the likely cause and is safe with your health and current medicines.
History and examination
The GP asks about:
- when the difficulty started, and whether it is occasional or persistent
- morning erections, libido and any pain or deformity
- current medicines, including heart and blood-pressure treatment
- diabetes, high blood pressure, high cholesterol, smoking and other circulation risk
- stress, sleep, alcohol and relationship strain, because these can sit alongside a physical cause
An examination is arranged when it would change the plan. The clinician explains each step, and you may ask to pause.
Erectile difficulty can have physical and psychological causes. Circulation problems, diabetes, hormone changes, medicines, stress and anxiety all appear in NHS guidance. The assessment looks for the combination that applies to you, rather than assuming a single explanation.
When blood tests help
The GP arranges blood tests when they could clarify a possible cause, such as diabetes, cardiovascular risk or a hormone change.
Tests that may be arranged
Relevant tests can include a male hormone profile, diabetes markers and cardiovascular testing. The GP interprets any result with the history and examination, because a blood result is not a diagnosis on its own.
A male hormone replacement consultation is the focused visit when testosterone replacement is already the question. Hormone testing may still form part of an erectile dysfunction assessment when the history suggests it would help.
Tablets the GP may prescribe
When the assessment supports it, the usual first treatment is an oral PDE5 medicine. The two names patients most often ask about are sildenafil and tadalafil.
Oral PDE5 medicines
After reviewing your health, medicines and cardiovascular risk, the GP may prescribe sildenafil or tadalafil when clinically appropriate, and explains how to use the tablet, common side effects and important interactions before any prescription is issued. Oral PDE5 medicines must not be taken with nitrate medication, so tablets are not prescribed if that combination would be unsafe. Pharmacy charges remain separate if a medicine is issued.
What happens if tablets are unsuitable or do not work
Some men cannot take PDE5 medicines safely. Others take them correctly and still have little benefit.
If tablets do not help
Treatment at Medical Express Clinic focuses on GP assessment and first-line oral medicines. If oral tablets are unsuitable or do not work, the GP can investigate further and refer you to an appropriate specialist, with the history and any test results already available.
Which assessment should you choose?
An erectile dysfunction assessment is the right visit when erection problems and first-line oral treatment are the main concern.
Other assessments that may fit
Urinary symptoms, a testicular lump, prostate concerns or a wider men's sexual-health problem should start with a men's urology assessment. That visit is GP-led, with consultant referral when it is needed.
A planned prostate screen, rather than a symptom review, is a prostate screening consultation.
Discharge, sores or a suspected sexually transmitted infection should go to the sexual health clinic.
Testosterone replacement is a separate decision. A male hormone replacement consultation is the focused visit when that is already the question.
Chest pain, severe breathlessness or a suspected heart attack needs 999 or A&E, not a planned ED enquiry.

A GP erectile dysfunction assessment at Medical Express Clinic starts from £150. Blood tests and pharmacy charges are separate when they are arranged.
Can you prescribe sildenafil or tadalafil?
The GP can prescribe sildenafil or tadalafil when an oral PDE5 medicine is clinically appropriate. The GP checks your medical history, current medicines and cardiovascular risk first. These medicines must not be taken with nitrates.
Will I need blood tests?
Not everyone does. Blood tests may be useful when the history suggests diabetes, cardiovascular risk or a hormone-related cause. The GP decides at the visit.
What happens if tablets do not work?
The GP can investigate possible medical causes and refer you to an appropriate specialist.
Is the visit confidential?

Should I book urology instead?
This assessment is for erectile function and first-line tablets when appropriate. A men's urology assessment is the better visit when urinary, testicular or prostate symptoms are the main concern.
Can I be seen today?
The next available assessment depends on current GP availability. The form or 0207 499 1991 will give the current timetable.
