Testosterone Replacement Therapy Request
Practise this SCA case with a voice-based AI patient that responds in real time — just like the real exam.
Clinical Scenario
Jake Turner, 42, a personal trainer, attends requesting testosterone replacement therapy. He has been experiencing fatigue, low libido, difficulty maintaining muscle mass despite regular training, and low mood for the past 6 months. He has self-diagnosed 'low testosterone' after reading about it online and on fitness influencer podcasts. He has not had any blood tests. He sleeps 5-6 hours per night, works 12-hour days, drinks 20 units of alcohol weekly, and his relationship is under strain. He wants a testosterone prescription today and becomes frustrated when you suggest investigation before treatment.
What This Case Tests
Understanding the evidence base for testosterone replacement therapy; conducting a thorough assessment before prescribing including appropriate blood tests; identifying lifestyle factors contributing to symptoms; managing a patient whose self-diagnosis has been influenced by online content; explaining why testosterone is not appropriate without confirmed deficiency; offering alternative explanations and management for his symptoms
Common Mistakes Trainees Make
The three most common mistakes are: prescribing testosterone without confirmed biochemical deficiency on two separate morning samples — this is not evidence-based and carries significant risks including polycythaemia, cardiovascular events, and infertility; dismissing the patient's concerns because his self-diagnosis came from the internet, when his symptoms are genuine and need proper assessment; and failing to identify the obvious lifestyle contributors — 5-6 hours of sleep, excessive work hours, 20 units of alcohol, and relationship stress are all independently sufficient to cause his symptoms.
The Consultation Challenge
Jake has arrived with a specific diagnosis and a specific treatment request. He is confident in his self-assessment. You need to take his symptoms seriously while redirecting toward evidence-based assessment.
Start by validating his symptoms: 'Jake, the symptoms you are describing — fatigue, low libido, difficulty with muscle mass, low mood — are real and significant, and I want to get to the bottom of what is causing them. I am glad you came in rather than just ordering something online.'
Then broaden the assessment. His lifestyle history reveals multiple contributing factors: chronic sleep deprivation (5-6 hours is insufficient for testosterone production, muscle recovery, and mood regulation), high alcohol intake (alcohol directly suppresses testosterone and disrupts sleep architecture), excessive work hours (12-hour days contribute to stress and poor recovery), and relationship strain (a significant psychosocial stressor).
Explain the testosterone testing pathway: 'Before we consider testosterone replacement, we need to confirm whether your levels are actually low. Testosterone fluctuates throughout the day and is highest in the morning, so I need two separate early morning blood tests — taken before 10am — showing low levels before we can diagnose deficiency. I will also check your thyroid, iron, and other hormone levels to rule out other causes.'
Address the online influence sensitively: 'I understand that testosterone has had a lot of attention online, and some of what you have read may be accurate. But there is also a lot of misinformation, particularly from fitness influencers who may be promoting products. The evidence is clear: testosterone replacement only helps if your levels are genuinely low, and prescribing it when levels are normal carries real risks — including blood clots, cardiovascular problems, and reduced fertility.'
Present the lifestyle factors as the most likely explanation: 'Here is what I think is most likely happening. You are sleeping 5-6 hours a night — testosterone is predominantly produced during deep sleep, and chronic sleep deprivation directly reduces testosterone levels. You are drinking 20 units weekly — alcohol suppresses testosterone production. And you are working 12-hour days under relationship stress. Any one of these factors alone could explain your symptoms. Before we go down the medication route, I think addressing these factors will make a significant difference.'
Offer a clear plan: morning blood tests (total testosterone, SHBG, LH, FSH, prolactin, TFTs, FBC, ferritin, HbA1c), review in 2 weeks with results, and meanwhile target the modifiable factors — prioritise 7-8 hours sleep, reduce alcohol to under 14 units, and consider relationship counselling.
Time check: Minutes 1-3 on validating symptoms and taking a thorough history. Minutes 3-6 on lifestyle assessment and identifying contributing factors. Minutes 6-9 on explaining the testing pathway and addressing the online influence. Final 3 minutes on management plan, blood tests, and follow-up.
How Examiners Mark This Case
Data Gathering and Diagnosis: Examiners assess whether you take a comprehensive history covering symptoms, lifestyle factors, and psychosocial context rather than jumping to blood tests. Identifying sleep deprivation, alcohol excess, and stress as contributing factors demonstrates clinical breadth. Knowing the correct testosterone testing protocol — two early morning samples — shows endocrine knowledge.
Clinical Management and Medical Complexity: Examiners evaluate whether you order appropriate blood tests (total testosterone, SHBG, LH, FSH, prolactin, TFTs), explain why testosterone should not be prescribed without confirmed deficiency, and present the risks of inappropriate testosterone use. Offering a lifestyle modification plan alongside investigation shows comprehensive management.
Relating to Others: Examiners look for validation of the patient's symptoms without colluding with his self-diagnosis. Managing his frustration when you do not prescribe today, addressing the online influence without being condescending, and presenting lifestyle changes as empowering rather than dismissive are all essential communication skills.
Example Opening
Strong opening: "Hello Jake, thanks for coming in. The symptoms you are describing sound like they are really affecting your quality of life, and I want to take them seriously. Before we talk about specific treatments, I need to understand the full picture — can you talk me through everything that has been going on?"
When declining to prescribe today: "I understand you were hoping to start testosterone today, and I can see why — you want to feel better. But prescribing without confirmed deficiency would actually be risky for you, and I do not think it is what is going on. Let me explain what I think is really causing your symptoms, because I think there is a clearer path to feeling better."
Avoid: "Testosterone is overhyped on social media" — this sounds dismissive of his research and intelligence. Instead, validate his proactivity while redirecting toward evidence.
How This Appears in the SCA
Testosterone requests test your ability to resist patient pressure for a specific treatment, conduct evidence-based assessment, and address the influence of online health misinformation. Examiners value candidates who take symptoms seriously while insisting on proper investigation before prescribing.
Key Statistic
True testosterone deficiency affects approximately 2% of men. However, lifestyle factors including sleep deprivation, obesity, alcohol excess, and chronic stress can reduce testosterone levels by 10-30%, often into the borderline range, and are reversible without medication.
Relevant Guidelines
- BSSM guidelines on testosterone deficiency in men
- NICE CKS: Testosterone deficiency in men
- Endocrine Society Clinical Practice Guideline on testosterone therapy
- NICE CG91: Depression in adults.
Frequently Asked Questions
What blood tests should I order when assessing for testosterone deficiency?
Request: total testosterone (must be an early morning sample before 10am), sex hormone-binding globulin (SHBG) to calculate free testosterone, LH and FSH (to differentiate primary from secondary hypogonadism), prolactin (pituitary cause), TFTs (thyroid disease mimics testosterone deficiency symptoms), FBC (polycythaemia baseline before any treatment), ferritin, and HbA1c (diabetes is associated with low testosterone). Two separate low morning testosterone results are required before diagnosing deficiency. A single borderline result is insufficient.
What are the risks of testosterone replacement in a man with normal levels?
Prescribing testosterone when levels are normal carries significant risks: polycythaemia (increased red blood cells increasing stroke and clot risk), suppression of natural testosterone production and spermatogenesis (potentially causing infertility), cardiovascular risk (evidence is mixed but caution is warranted), liver toxicity with oral preparations, sleep apnoea exacerbation, mood disturbance including aggression, and prostate stimulation. These risks are only justified when there is confirmed biochemical deficiency with associated symptoms.
How does sleep deprivation affect testosterone levels?
Testosterone is predominantly produced during deep sleep, with peak production in the early morning hours. Studies show that sleeping 5 hours per night for one week reduces testosterone levels by 10-15% compared with sleeping 8 hours. Chronic sleep deprivation can reduce testosterone into the borderline-low range, creating symptoms identical to hypogonadism. For Jake, sleeping 5-6 hours nightly is almost certainly contributing to his symptoms. Improving sleep to 7-8 hours may resolve his testosterone-related complaints without any medication.
How do I address online health misinformation about testosterone without being dismissive?
Acknowledge the patient's proactivity: 'I am glad you have been researching this — it shows you are taking your health seriously.' Then redirect: 'Some of the information online is accurate, but there is also a lot of content driven by people selling products rather than providing evidence-based advice. What the medical evidence actually shows is...' Frame yourself as an ally in interpreting the information rather than an authority shutting down their research. Offer reputable sources if they want to read further.
What lifestyle changes can improve testosterone levels naturally?
The most impactful changes are: improving sleep to 7-8 hours per night (testosterone production depends on deep sleep), reducing alcohol below 14 units per week (alcohol directly suppresses testosterone synthesis), maintaining a healthy weight (adipose tissue converts testosterone to oestrogen via aromatase), regular resistance training (which Jake already does), stress management (cortisol directly suppresses testosterone), and ensuring adequate vitamin D and zinc intake. These changes can increase testosterone by 10-30% and should be trialled before considering pharmaceutical intervention.
