How to talk to your GP about erectile dysfunction
What actually happens when you see a GP about erectile dysfunction: common causes, the tests to expect, and the questions worth asking.

Erection problems are one of the most common reasons men delay a GP appointment, and one of the best-understood things a GP deals with. Most men have occasional difficulty: stress, alcohol and exhaustion see to that. When it keeps happening over weeks and months, it has a medical name, erectile dysfunction, and it deserves a proper look rather than private worry.
Here’s the fact that reframes the whole subject: persistent ED is often a circulation signal. The arteries that supply the penis are narrow, so when blood vessels start to fur up, erections are frequently affected years before anything shows up around the heart. That’s not a scare line. It’s the reason a GP will treat your appointment as useful medical information, not an awkward confession.
How an erection actually works
An erection is a plumbing-and-wiring collaboration. Arousal signals from the brain travel down nerves to the blood vessels of the penis, which relax and let blood flood into two sponge-like chambers. As they fill, they compress the veins that normally drain blood away, which traps it there. Pressure builds, and stays until the signals stop.
That means at least four systems have to cooperate: your brain and mood, your nerves, your hormones, and, above all, your blood vessels. A fault anywhere in the chain can cause the same end result, which is why “what’s causing it?” is a genuinely open question that a GP answers with history-taking and blood tests rather than guesswork.
Common causes
GPs think in categories, and it helps to know them:
- Vascular. Narrowing of the arteries (atherosclerosis) is one of the most common physical causes, especially from the 40s onward. High blood pressure and raised cholesterol both contribute.
- Metabolic. Diabetes, including undiagnosed type 2, can affect both the blood vessels and the nerves involved.
- Hormonal. Low testosterone or thyroid problems can reduce desire and erection quality. Less common than the vascular causes, but easy to test for.
- Neurological. Conditions or injuries affecting nerve signals, and some pelvic surgery, can play a role.
- Medication side effects. Some antidepressants, blood pressure medicines and other prescriptions list erectile problems as a known side effect. Never stop a medicine on your own, flag it to your GP.
- Psychological. Stress, low mood, performance anxiety and relationship strain are real physical forces here, because arousal starts in the brain. One or two disappointing experiences can create an anxiety loop that keeps the problem going even after the original cause has passed.
- Lifestyle. Smoking, heavy drinking and being sedentary all work against the blood vessels doing the job.
Usually it’s not one cause but a stack of them. That’s actually good news: several of the items on that list are measurable, and most are treatable or reversible.
Why GPs take it seriously
Because ED can arrive ahead of cardiovascular disease, guidance for UK clinicians is that men presenting with it should have a cardiovascular risk assessment: blood pressure, weight, smoking status and blood tests. Research suggests erection problems can precede heart problems by several years, and the younger the man, the more meaningful the signal.
Seen that way, booking the appointment isn’t admitting a weakness. It’s using the earliest warning light on the dashboard while there’s the most time to act.
Before the appointment
Two minutes of preparation makes the consultation far more useful. Jot down:
- How long it’s been happening, and whether it came on gradually or suddenly.
- Whether it’s every time or situational: fine sometimes, not others.
- Morning erections: present, absent, or reduced. (More on why this matters below.)
- Your medicines, including anything bought online or over the counter.
- Roughly how much you drink and whether you smoke. The GP isn’t grading you; the answers change which causes are likely.
- What’s going on in your life, work stress, relationship tension, low mood, poor sleep.
Booking tactics, if the phone call is the hard part: you don’t have to explain anything to the receptionist. “a private matter” or “a men’s health issue” is plenty. You can ask for a male or female GP if that makes it easier, request a phone consultation to start, or use your surgery’s online form and simply write “erection problems” in the box. GPs see this weekly. You will not be the story they tell at dinner.
What the appointment looks like
A standard appointment is around ten minutes, and most of it is conversation. Expect questions covering the list above, plus your medical and family history. One question surprises people: “Do you still get morning erections?” It’s a genuinely clever diagnostic shortcut. If night-time and morning erections still happen normally, the machinery is likely working, which points more towards psychological or situational causes. If they’ve faded too, a physical cause becomes more likely.
The examination, if there is one, is usually undramatic: blood pressure, weight, sometimes heart rate. The GP may offer a brief genital examination to rule out physical changes. It takes seconds, you can decline, and you can ask for a chaperone.
Then blood tests, usually done separately at the surgery: typically blood sugar (HbA1c) to check for diabetes, cholesterol, and often testosterone: which is drawn in the morning, when levels are highest, so you may be asked to come back before 11am.
That’s the whole event. Ten minutes of questions, a cuff on your arm, a form for a blood test.
Questions worth asking your GP
Take this list on your phone:
- Could this be linked to my heart or circulation, and should I have my cardiovascular risk assessed?
- Could any of my current medicines be contributing?
- Which blood tests are you ordering, and what will they tell us?
- How much difference could alcohol, smoking, sleep or exercise realistically make in my case?
- If the tests come back normal, what’s the next step?
- Is talking therapy or psychosexual counselling relevant for me, and can I be referred?
- When should I come back if things don’t improve?
You won’t need all seven. Having them written down means the appointment ends with a plan instead of a vague “come back if it continues”.
What happens next
Depending on what the history and tests show, the GP will talk you through options. These can include treating an underlying condition, adjusting an existing prescription, specific lifestyle changes, prescribed medication, or referral: to a specialist clinic, or to talking therapy where anxiety or relationship strain is driving the loop. What’s right for you depends entirely on the cause, which is the whole argument for going in rather than self-diagnosing.
One caution belongs in any honest article on this subject: be wary of websites and shops selling pills, herbal blends or “male enhancement” products for erection problems. Unregulated products can contain undeclared prescription-strength ingredients, wrong doses, or nothing useful at all, and they skip the medical check that makes treatment safe. The check that might also catch a circulation or blood sugar problem early. Medicines for ED should come via a doctor or a registered UK pharmacy after a proper consultation, full stop.
Common questions
Should I see a GP about erectile dysfunction, or will it go away on its own?
Occasional problems after a stressful week or a heavy night are normal and usually pass. If erections have been unreliable for more than a few weeks, or the problem keeps coming back, the NHS advises seeing your GP, because persistent ED can be an early sign of a treatable condition such as high blood pressure or diabetes. You can also use an NHS sexual health clinic, many of which offer a walk-in service, if that feels easier than your surgery.
What do I actually say to the receptionist and to the GP?
To the receptionist, “a private matter” or “a men’s health issue” is enough; you never have to explain. Many surgeries also let you book through an online form where you can simply write “erection problems”. With the GP, one plain opening sentence does the job: “I’ve been having trouble getting or keeping erections for about three months and I’d like to look into it.” From there the GP leads with questions, so you do not need a prepared speech.
What will the GP do at the appointment for erectile dysfunction?
Mostly talk. Expect questions about how long it has been happening, whether it is every time or only sometimes, morning erections, medicines, alcohol, smoking, mood and relationships, plus your medical history. The GP will usually check blood pressure and weight, and may offer a brief genital examination, which you can decline or have with a chaperone. Blood tests typically follow: HbA1c for diabetes, cholesterol, and often a testosterone level, taken in the morning when it is highest.
Is erectile dysfunction really a sign of heart problems?
It can be. The arteries supplying the penis are narrow, so fatty build-up in the blood vessels (atherosclerosis) often affects erections before it causes any chest symptoms. The British Heart Foundation describes erection problems as one of the first warning signs of narrowed arteries, and UK guidance is that men with ED should have their cardiovascular risk assessed. That is why the GP checks blood pressure, weight, smoking and blood tests: catching it early gives you the most time to act.
Will the GP prescribe something for erectile dysfunction?
Sometimes, but not before the assessment. Once the GP has your history, blood pressure and blood test results, they will talk through options that depend on the cause: treating an underlying condition, adjusting a medicine, lifestyle changes, prescribed treatment, or referral to a specialist clinic or talking therapy. A GP will not skip the check, because the point of the appointment is to find the cause. Be wary of websites selling pills or herbal products for erection problems; they skip that check and may contain undeclared ingredients.
Can I get erectile dysfunction in my 30s, and should I still see a GP?
Yes. ED is more common with age but affects younger men too, often with a psychological element such as performance anxiety, stress, low mood or heavy drinking. It is worth seeing a GP, because the advice to get persistent problems checked applies at any age, and a physical cause in a younger man is a more meaningful signal about blood vessels or blood sugar. If anxiety is driving the loop, ask about talking therapy or psychosexual counselling; in England you can refer yourself to free NHS talking therapies.
