UK TRT care should start with diagnosis
UK and international guidance emphasise that TRT should be linked to a clear diagnosis of testosterone deficiency. That means symptoms and consistently low testosterone results should be considered together, with further assessment to understand whether the cause is primary, secondary, functional, medication-related, or connected to wider health factors.
A doctor-led pathway should also check whether TRT is inappropriate or needs specialist caution. Important considerations include fertility plans, prostate risk, high haematocrit, untreated severe obstructive sleep apnoea, recent major cardiovascular events, uncontrolled heart failure, and relevant medication use.
Monitoring is part of the treatment
Follow-up is not optional. Monitoring helps doctors assess symptom response, testosterone exposure, haematocrit, PSA where relevant, side effects, and whether the dose or formulation should change. Men should also understand that TRT can suppress fertility and may not be suitable when near-term fertility is a priority.
