Your GP is going to tell you no.
Not necessarily because he's wrong, but because GPs are trained to be risk-averse, they work under NHS constraints that make specialist testing expensive and slow, and many simply don't have good training in male hormone health.
But you need to have the conversation. And if you say the wrong thing, the door closes immediately.
This guide gives you the exact approach, the script, and the fallback options when your GP inevitably says they don't think you need testing.
Why GPs Are Reluctant
Let's understand the barrier first.
Training gap: Most GPs don't receive substantial training in male hormone health. They know about testosterone in the context of things like anabolic steroid misuse (a real problem in their populations). They don't know much about hypogonadism or TRT outside of that context.
NHS cost pressures: Testing testosterone requires bloodwork, interpretation, and potentially ongoing monitoring. The NHS budgets are stretched. A GP can prescribe an SSRI for £5 a month. Testosterone testing and TRT cost more in terms of administration time.
Liability concerns: There's a (overstated) concern that testosterone therapy is dangerous, increases cardiovascular risk, or makes men aggressive. This is largely unfounded, but it contributes to reluctance.
"Normal range" rigidity: Many GPs interpret a testosterone result of 350 ng/dL as "normal" because it's within the reference range (typically 264–916 ng/dL). They don't consider that a man who's symptomatic at 350 may benefit from optimisation. They look at the number, not the patient.
Lack of interest in optimisation. GPs are trained in illness management. Testosterone optimisation (especially in the low-normal range) is seen as "lifestyle" or "optimisation," not "medicine." It's not their framework.
None of this means your problem isn't real or doesn't warrant investigation. It means you need to be strategic.
The Right Frame
Here's the key: Don't frame this as "optimisation," "anti-ageing," or "building muscle." Frame it as investigation of a potential medical problem.
Your GP's job is to investigate symptoms and find causes. If your symptoms might be caused by hormonal dysfunction, your GP should investigate. That's fair.
The Script
You: "I've been experiencing persistent symptoms that might be hormonal. I'd like my testosterone checked to rule out hypogonadism as a cause. Here are my symptoms." [Present your symptom list, below.]
Key frame: "Rule out hypogonadism" is clinical language. You're asking for investigation, not asking for a diagnosis or treatment.
What Symptoms to Present
Write these down before your appointment. Bring them. This matters because:
- You're less likely to forget things under pressure
- You look like you've thought this through (you have)
- GPs respond better to structured information
- It creates a medical record of your symptoms
Good symptoms to present (low testosterone causes these):
- Persistent fatigue despite adequate sleep
- Reduced motivation or drive (in work, exercise, or other activities)
- Decreased libido or erectile dysfunction
- Loss of muscle mass or difficulty maintaining muscle despite training
- Increased body fat, especially around the abdomen
- Difficulty concentrating or mental fog
- Reduced confidence or increased anxiety
- Irritability
What to emphasise: Choose the 2–3 symptoms that are most bothersome to you. The fatigue and motivation loss are most impactful with GPs (they suggest genuine dysfunction, not just fitness concern). Erectile dysfunction is also very effective (it's a recognised sign of hypogonadism).
Avoid: "I want more muscle," "I want to improve my performance," "I feel like I should have higher testosterone." These sound like optimisation, not medical investigation.
When to Have the Appointment
What time of day: Book a longer appointment (15–20 minutes if possible, not the standard 10-minute slot). Tell the receptionist it's for a complex issue. Some surgeries allow you to book a double slot.
When in your cycle: If you've had worse periods of fatigue or low motivation, book after a bad week. Bring notes about patterns if you have them.
What Tests to Request
Your GP will ask "What do you want me to test?" Be specific:
"I'd like at minimum: total testosterone, LH, FSH, and SHBG. If possible, also free testosterone, prolactin, and TSH to rule out other contributors."
By being specific, you look informed without being pushy. You're asking for a sensible, reasonable panel—not some aggressive hormone-maximisation protocol.
Why these tests:
- Total testosterone: Your absolute testosterone level
- LH and FSH: Determine if your pituitary is functioning (distinguishes primary hypogonadism from secondary)
- SHBG: Affects how much testosterone is "free" (biologically active)
- Free testosterone: The active form
- Prolactin: Elevated prolactin suppresses testosterone
- TSH: Thyroid dysfunction mimics low testosterone
The Bloodwork Protocol
If they agree to test, give yourself the best chance of an accurate result:
Timing: Morning (testosterone is highest). Fasted (overnight fast, no food since 8 PM the night before).
Activity: No exercise for 24–48 hours before the test. Acute exercise raises testosterone acutely, which clouds the picture.
Stress: Sleep well the night before. Don't be stressed about the appointment (I know, hard). Acute stress raises cortisol, which can suppress testosterone temporarily.
Getting the result: After testing, ask when results will be available. Follow up proactively. Don't wait passively for your GP to contact you—call the surgery after 5–7 days and get the numbers.
Write down the numbers: Ask for the actual values, not just "normal" or "abnormal." You need the data to interpret it yourself and to track changes.
Interpreting the Result
If total testosterone is below 350 ng/dL: This is genuinely low and problematic. Most GPs will acknowledge this needs addressing.
If it's 350–450 ng/dL: This is low-normal. You're in a range where some men are symptomatic. A GP might dismiss this as "normal," but you can argue that at this level, with your symptoms, investigation and optimisation are warranted.
If it's 450–600 ng/dL: The GP will definitely say it's normal. At this level, if you're symptomatic, your symptoms are probably multifactorial (sleep, stress, training, diet) rather than primarily hormonal. Still, if your LH/FSH are low, this suggests secondary hypogonadism and might warrant investigation.
If it's above 600 ng/dL: Your testosterone is not the primary problem. But get your other tests (prolactin, TSH, cortisol) checked to rule out other contributors.
What to Do If They Refuse
If your GP refuses to test, here's what to do:
Push back, politely:
"I understand testosterone isn't tested routinely, but I'm experiencing [symptoms] that could be consistent with hypogonadism. The cost of the test is minimal, and it's a straightforward investigation. I'd appreciate if we could run it to rule this out."
If they still refuse:
"I'd like this documented in my medical record as a request I made and you declined. Can we note that?"
Documentation matters. You want it on record that you asked and were refused. This:
- Sometimes motivates GPs to just do the test
- Gives you grounds for a complaint if you want to go that route
- Documents your symptom history
If they continue to refuse:
The private route is a reasonable alternative. You don't need your GP's permission to get private bloodwork.
The Private Route
If your NHS GP refuses or drags their feet, you can:
Private bloodwork: Companies like Medichecks, Thriva, and others allow you to order bloodwork directly. You book an appointment at a private clinic, get your blood drawn, and get results within 5–7 days. Cost: £80–150 for a basic testosterone panel, £200–300 for a comprehensive hormone panel.
Private GP consultation: If you want a doctor to interpret your results and discuss options, you can see a private GP. Some clinics specialise in men's health and hormone optimisation. Cost: £150–300 per consultation.
Telehealth: Some private clinics offer remote consultations (you get bloodwork done locally, then video call with a doctor). This is cheaper and easier than in-person.
TRT providers: If your private testing shows low testosterone, some private clinics offer TRT with ongoing monitoring. Cost: £200–400 per month typically, depending on the dose and clinic.
Is private expensive? More than NHS, yes. But if your symptoms are genuinely affecting your quality of life, the cost is often worth it. Many men do a private baseline test, get TRT started privately for a few months, then transition back to NHS care once their testosterone is stable and they have documentation.
The Useful Data to Have
Before your appointment, gather:
Symptom timeline: When did you first notice fatigue/motivation loss? Did it coincide with anything (job change, breakup, injury)? Is it getting worse? Write this out. 2–3 sentences.
Your baseline: If you've had bloodwork before (standard NHS bloods, not specifically testosterone), what were the results? Bring them.
Family history: Does hypogonadism run in your family? Or early erectile dysfunction? Mention it. It adds weight to the investigation.
What you've tried: Have you tried improving sleep, exercise, diet? Have you noticed any changes? If you've made real effort and symptoms persist, it suggests a physiological problem, not lifestyle.
Medications: Are you on anything that might suppress testosterone? Some antidepressants, antihistamines, statins can affect testosterone. Mention if relevant.
This all goes into a 1-page brief you can hand your GP if needed.
The Conversation Structure
-
Open with symptoms: "I've been experiencing [symptom list] for [duration]. I'd like to rule out hypogonadism."
-
Provide context: "I've tried [improvements], but symptoms persist."
-
Request specific testing: "I'd like total testosterone, LH, FSH, and SHBG at minimum."
-
Be collaborative: "I know you're busy, but this would help me understand what's going on. If the result is normal, great—we can investigate other causes."
-
If refused, escalate carefully: "I'd like this documented in my record as a request I made."
What Happens After Testing
If low: Expect discussion of TRT or natural optimisation strategies. Be prepared to discuss options.
If low-normal and symptomatic: Argue for optimisation: "My symptoms are substantial. Can we try optimisation strategies first—sleep, training, supplementation—and retest in 8 weeks?"
If normal: Discuss other contributors: sleep quality, stress, thyroid, training. Don't assume you're imagining the symptoms.
The Bottom Line
Getting your testosterone tested isn't unreasonable. It's a basic investigation of a potential medical problem. Most GPs will do it if you ask clearly and frame it as investigation, not optimisation.
If they refuse, the private route is available and often quicker than dealing with NHS barriers.
