Testosterone Replacement Therapy (TRT) in the UK
Testosterone Replacement Therapy (TRT) has gained significant traction in recent years as more men across the UK become aware of the impact of low testosterone on their health and well-being. This detailed guide explores what TRT is, who it’s for, how it works, and what to expect if you’re considering treatment in the UK.
ADAM Questionnaire Low Testosterone Test
The ADAM questionnaire is 88% sensitive in detecting low testosterone.
What Is Testosterone Replacement Therapy?
Testosterone Replacement Therapy (TRT) is a medical treatment designed to restore testosterone levels in men who are suffering from hypogonadism — a condition where the body fails to produce adequate testosterone. This can be due to aging, injury, illness, or other medical conditions.
TRT typically involves administering testosterone through gels, injections, patches, or tablets, and is overseen by a qualified medical professional.
Why Testosterone Matters
Testosterone is the primary male sex hormone responsible for regulating sex drive, bone mass, fat distribution, muscle mass, and the production of red blood cells and sperm. Low levels can result in:
Fatigue and low energy
Decreased libido and erectile dysfunction
Mood swings and depression
Reduced muscle mass and strength
Difficulty concentrating

Who Should Consider TRT in the UK?
TRT is not a one-size-fits-all treatment. It’s best suited for men who:
Have clinically low testosterone levels (confirmed via blood test)
Experience symptoms that interfere with their quality of life
Have no contraindications like prostate cancer or severe heart conditions
Always consult with a medical professional for proper diagnosis and to explore treatment suitability.
How to Get TRT in the UK There are two primary paths to receiving TRT in the UK:
NHS: The National Health Service may offer TRT, but eligibility is strict, and waiting times can be long.
Private Clinics: Many men opt for private testosterone clinics that provide faster access, thorough testing, and tailored treatment plans.
Private providers like Testosteronerehab offer a convenient and expert-led pathway to hormone health, with discreet service and ongoing monitoring.
The Process of Starting TRT The TRT journey typically includes:
Initial Consultation: Discuss symptoms, medical history, and expectations.
Blood Testing: Comprehensive hormone panel to confirm low testosterone.
Diagnosis and Plan: If eligible, you receive a customised treatment plan.
Ongoing Monitoring: Regular follow-ups ensure optimal dosing and safety.

Which Blood Tests Do You Need Before Starting TRT in the UK?
Before beginning Testosterone Replacement Therapy (TRT), a full diagnostic workup is essential. Clinics in the UK — especially private TRT providers — typically require the following blood tests to ensure treatment is safe, appropriate, and personalised:
1. Total Testosterone
This is the primary test to confirm low testosterone levels. It measures the total amount of testosterone in your bloodstream.
2. Free Testosterone
Free testosterone represents the active form not bound to proteins. Low free T levels can explain symptoms even if total testosterone is borderline.
3. Luteinising Hormone (LH)
Helps determine if your testosterone deficiency is due to primary (testicular) or secondary (pituitary) hypogonadism.
4. Follicle-Stimulating Hormone (FSH)
Assesses sperm production and pituitary function, especially important if fertility is a concern.
5. Sex Hormone Binding Globulin (SHBG)
This protein binds to testosterone and affects how much free testosterone is available in the body.
6. Prolactin
High prolactin levels can suppress testosterone and indicate possible pituitary issues.
7. Oestradiol (Estrogen)
Monitoring this hormone is important, as elevated levels can cause side effects during TRT.
8. Full Blood Count (FBC)
Checks for polycythemia — an increase in red blood cells — which can be a side effect of TRT.
9. PSA (Prostate-Specific Antigen)
Especially for men over 40, PSA testing helps screen for prostate abnormalities before starting therapy.
10. Liver and Kidney Function Tests
Ensure your organs are functioning well enough to process hormone therapy safely.
These tests form the foundation of a responsible TRT program. A reputable UK clinic like Testosteronerehab will never begin treatment without this comprehensive blood work. It ensures you get the right care — safely and effectively.
