About the Condition
Testosterone Replacement
Testosterone is the primary male sex hormone, essential for maintaining energy, muscle mass, cognitive function, libido, and emotional well-being. It regulates everything from bone density to red blood cell production.
Natural production typically peaks in early adulthood and decreases gradually after age 30. However, factors like chronic stress, poor diet, and underlying health conditions can significantly accelerate this decline at any age.
- Affects millions of men — not just an ageing issue
- Diagnosis requires blood testing, not symptoms alone
- Treatment is highly individualised per patient
- Ongoing monitoring is part of every protocol

Low testosterone, or hypogonadism, occurs when the body produces insufficient testosterone. It can lead to fatigue, low libido, and changes in body composition.
Symptoms may include tiredness, loss of sex drive, erectile dysfunction, reduced muscle mass, mood swings, and poor focus.
You will need to complete a comprehensive hormone blood panel before your consultation. This includes total testosterone, LH, FSH, haematocrit, PSA, and a range of metabolic markers. These results give Thomas Harries the clinical data needed to make a proper assessment and, where appropriate, a prescribing decision. You will be given clear instructions on how to arrange your blood tests when you register your interest.
Yes, when prescribed and monitored by a healthcare professional. Regular blood tests are required to track hormone levels and detect any side effects.
Treatment includes hormone replacement therapy through gels or injections to restore normal testosterone levels and relieve symptoms.
Ongoing monitoring is built into the programme from the start. Once treatment begins, you will have regular follow-up blood tests to track your testosterone levels alongside haematocrit, PSA, and other key markers. Review consultations are scheduled at appropriate intervals. Dose adjustments are made based on your results and clinical response. TRT is not a set-and-forget treatment, and PrimeLife manages it with the clinical rigour it requires.
