Urologist for ED: When to See a Specialist and Your Treatment Options

Published: 17 October 2026

A urologist for ED is a specialist doctor who diagnoses and treats erectile dysfunction when first-line treatments have not worked or when there is an underlying structural, hormonal or complex medical cause. Most men with ED do not need to see a urologist; your GP can assess you, arrange blood tests, review your medications and prescribe oral treatments such as sildenafil or tadalafil [1][2]. If these measures are unsuccessful, or if your GP suspects a specific urological problem, they may refer you to a urologist for further investigation and specialist options.

What does a urologist for ED do?

A urologist is a surgeon who specialises in conditions of the urinary tract and male reproductive organs. When you are referred for erectile dysfunction, the urologist will take a detailed medical and sexual history, examine you (including checking blood pressure, pulse and genital anatomy), and review any blood tests or scans your GP has already arranged [2][8].

They may order additional investigations such as penile Doppler ultrasound to assess blood flow, nocturnal penile tumescence testing to distinguish physical from psychological causes, or hormone profiles if testosterone deficiency is suspected. Based on these findings, the urologist can recommend specialist treatments including vacuum erection devices, penile injections (alprostadil), intraurethral therapy, or—in selected cases—penile implant surgery [7][8].

Most importantly, a urologist will look for reversible causes: for example, Peyronie's disease (curvature or plaques in the penis), venous leak (blood draining too quickly from the penis), or anatomical abnormalities. They work closely with your GP and, where relevant, cardiologists, endocrinologists and psychosexual therapists to provide comprehensive care [2].

When should you see a urologist for ED?

You do not usually need a urologist for ED at the outset. The first step is to speak to your GP, who will check for common causes such as diabetes, high blood pressure, high cholesterol, low testosterone, depression, or side effects from medicines [1][2]. Your GP can also prescribe oral PDE5 inhibitors—sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra) or avanafil (Spedra)—which help most men achieve erections sufficient for sex [3][4][5][6].

A referral to a urologist is appropriate if oral tablets do not work despite trying different doses and types, if you have a physical abnormality (such as a bent or painful erection), if blood tests suggest a hormonal or vascular problem that needs specialist input, or if you are a young man with lifelong ED where no obvious cause has been found [2][8]. Urologists also see men who have had pelvic surgery (for example, prostate or bladder cancer treatment) or pelvic trauma, as these can damage the nerves and blood vessels needed for erections.

If you experience sudden-onset ED alongside chest pain, breathlessness or other cardiovascular symptoms, your GP may refer you urgently to cardiology rather than urology, because ED can be an early warning sign of heart disease [1][10]. Always seek same-day medical advice if you develop chest pain during sexual activity.

Can you access treatment without seeing a urologist?

Yes. The majority of men with ED are successfully treated in primary care or through a registered online pharmacy without needing a urology referral [2]. At Cured Pharmacy (GPhC 9012511), you complete a confidential online consultation that is reviewed by a UK-registered prescriber—either a GP or a pharmacist independent prescriber. If the treatment is safe and suitable for you, your prescription is dispensed and delivered discreetly to your home. This service is ideal for straightforward ED where you do not have complex medical conditions or contraindications to oral medicines.

Understanding the causes of erectile dysfunction

Erectile dysfunction has many causes, often overlapping. Physical causes include reduced blood flow to the penis (atherosclerosis, diabetes, high blood pressure), nerve damage (diabetes, multiple sclerosis, spinal injury, pelvic surgery), hormonal imbalance (low testosterone, thyroid disorders), and side effects of medicines such as certain antidepressants, beta-blockers and diuretics [1][2][10].

Psychological factors—stress, anxiety, depression, relationship difficulties—can trigger or worsen ED, and performance anxiety often creates a cycle that perpetuates the problem [1]. Lifestyle factors such as smoking, heavy alcohol use, obesity and lack of exercise all increase the risk of ED, partly because they damage blood vessels and nerves [10].

Because ED shares risk factors with cardiovascular disease, it can be an early warning sign of heart problems or diabetes. That is why your GP will usually arrange blood tests (glucose, cholesterol, testosterone) and a cardiovascular risk assessment when you first report erection difficulties [1][2]. Treating the underlying cause—for example, improving blood sugar control, stopping smoking, or switching an offending medicine—can sometimes restore erections without needing additional medication.

Oral treatments for ED: how they work and who can use them

The first-line medical treatment for erectile dysfunction is a group of medicines called PDE5 inhibitors: sildenafil (Viagra), tadalafil (Cialis), vardenafil (Levitra) and avanafil (Spedra) [1][2][3][4][5][6]. These tablets work by relaxing the smooth muscle in the blood vessels of the penis, allowing more blood to flow in when you are sexually aroused. They do not cause an automatic erection; sexual stimulation is still needed [9].

Sildenafil is taken about one hour before sex and lasts around four to six hours; tadalafil can be taken on-demand (effect lasts up to 36 hours) or as a low daily dose; vardenafil works within 25–60 minutes; and avanafil is the fastest-acting, often effective within 15–30 minutes [3][4][5][6][11]. All are taken at most once a day. In clinical trials, these medicines helped the majority of men achieve erections firm enough for penetration [9].

PDE5 inhibitors are not suitable for everyone. You must not take them if you use nitrate medicines (GTN spray, isosorbide mononitrate or dinitrate) for angina, nicorandil, riociguat, or recreational drugs called 'poppers', because the combination can cause a dangerous drop in blood pressure [3][4]. Men taking alpha-blockers for prostate symptoms need a lower starting dose and careful monitoring. Your prescriber will check your full medical history and current medicines during the consultation to ensure the treatment is safe for you [2][12].

Choosing between sildenafil, tadalafil, vardenafil and avanafil

The choice depends on how spontaneous you want to be, how long you want the effect to last, and any side effects you experience. Sildenafil and vardenafil need to be timed before sex, whereas tadalafil's long duration (up to 36 hours) offers more flexibility—many men prefer this 'weekend pill' effect [4]. Avanafil's rapid onset suits men who want a faster-acting option [6][11]. All four are similarly effective overall; if one does not work well or causes side effects (headache, flushing, indigestion, nasal congestion), switching to a different PDE5 inhibitor often helps [2]. Your prescriber can guide you, and it is safe to try different options on separate occasions (never take two PDE5 inhibitors together).

What happens during a urologist for ED consultation?

If your GP refers you to a urologist, the appointment will usually take place in a hospital outpatient clinic or a private urology practice. The urologist will ask detailed questions about when your ED started, whether it is constant or intermittent, the quality of your erections (including morning and nocturnal erections), your libido, any pain or curvature of the penis, and your general health and medications [2][8].

A physical examination includes checking your blood pressure, heart rate, abdomen, and external genitalia. The urologist may examine the penis for plaques (Peyronie's disease), assess testicular size, and perform a digital rectal examination if prostate problems are suspected. Blood tests—if not already done—will check testosterone, glucose, lipids, and sometimes prolactin and thyroid function [2].

Depending on the findings, the urologist may arrange a penile Doppler ultrasound (an injection is given to induce an erection, then ultrasound measures blood flow) or other imaging. They will then discuss treatment options, which may include continuing or adjusting oral medication, teaching you to use penile injections (alprostadil), prescribing a vacuum pump, or—rarely—considering surgery such as a penile prosthesis [7][8]. The urologist will also address any underlying condition, for example referring you to endocrinology if testosterone is very low, or to a psychosexual therapist if psychological factors dominate.

Accessing ED treatment through Cured Pharmacy

You complete a short online consultation covering your medical history, current medicines, and any heart, liver or kidney problems. A UK-registered prescriber—either a GP or a pharmacist independent prescriber—reviews your answers, and if the treatment is safe and appropriate, your prescription is dispensed and posted in discreet, unbranded packaging.

We stock a full range of PDE5 inhibitors at transparent prices: Sildenafil from £0.45 per tablet (£0.36 with first-order code Ednew), Tadalafil from £7.95 (£6.36 with code Ednew), Sildenafil 100mg (Teva) at £16.99 (£13.59 with code), Tadalafil 20mg (Teva) at £9.99 (£7.99 with code), Avarante (tadalafil) 10mg at £11.49 (£9.19 with code), Vardenafil at £16.95 (£13.56 with code), Spedra (avanafil) at £20.95 (£16.76 with code), branded Viagra at £37.95 (£30.36 with code), and branded Cialis at £12.00 (£9.60 with code). All prices include the prescriber review and delivery.

This service is suitable for men with straightforward ED who do not have contraindications to oral treatment. If the prescriber identifies a concern—for example, uncontrolled high blood pressure, recent stroke, or a medicine interaction—they may decline the prescription and advise you to see your GP or, if appropriate, request a urology referral. Our goal is safe, effective treatment delivered with professionalism and discretion.

When to see your GP instead of using an online service

You should see your GP in person if this is the first time you have experienced ED, if you have chest pain or breathlessness, if your ED came on suddenly, if you have pain or curvature of the penis, or if you have not had recent blood tests for diabetes, cholesterol and testosterone [1][2]. Your GP can perform a full cardiovascular assessment and arrange any necessary investigations or referrals. Online pharmacies are best suited to ongoing treatment once a diagnosis is established and you know oral medication is safe for you.
