Testosterone replacement therapy (TRT) is one of the most established treatments in men's health medicine in Australia. For men experiencing symptoms of low testosterone - confirmed through blood testing - it is a TGA-approved treatment with a clear regulatory framework and well-understood clinical evidence. The challenge for many men is finding a GP or specialist willing to take the diagnosis seriously and manage ongoing treatment properly.
Who is testosterone therapy for?
Testosterone therapy is medically indicated for men with clinically confirmed hypogonadism - low testosterone levels combined with symptoms that affect quality of life. Symptoms may include:
- Persistent fatigue and reduced energy
- Reduced libido and sexual function
- Loss of muscle mass despite training
- Increased body fat, particularly central adiposity
- Reduced motivation, mood changes, or difficulty concentrating
- Sleep disturbances
The diagnosis requires blood testing - typically two fasting morning testosterone measurements, along with LH, FSH, and other relevant markers to determine whether low T is primary (testicular) or secondary (hypothalamic or pituitary) in origin.
Testosterone therapy is not medically indicated solely for 'optimisation' in men with normal testosterone levels, though some clinics do offer such programs. This is a conversation to have with your doctor, who should be honest about the evidence.
How access works in Australia
Testosterone preparations are Schedule 4 (S4) prescription-only medications in Australia. They can only be legally prescribed by an AHPRA-registered medical practitioner following an appropriate clinical assessment.
Common TGA-registered testosterone preparations available in Australia include:
- Injectable testosterone - typically testosterone enanthate or testosterone undecanoate, administered every 2-12 weeks depending on the preparation
- Topical testosterone - gel or cream formulations applied daily, available as registered products or through compounding pharmacies
- Testosterone implants (pellets) - surgically implanted subdermal pellets, offered by some specialist clinics
The prescribing pathway typically involves a GP referral to an endocrinologist or urologist for diagnosis confirmation, though some GP practices with a men's health focus manage TRT directly. Dedicated men's health clinics with medical directors experienced in testosterone management also operate across Australia.
What a quality TRT program involves
A well-structured testosterone therapy program should include:
Find a Clinic
Compare doctor-supervised clinics - telehealth or in-person, filtered by your goal and state.
Baseline bloodwork - testosterone (two morning fasting tests), LH, FSH, SHBG, oestradiol, full blood count, PSA (men over 40), and liver function as a minimum.
A thorough health history - particularly regarding cardiovascular risk, prostate health, fertility intentions (TRT suppresses sperm production - relevant for men who want to father children), sleep apnoea, and existing red blood cell count.
Informed consent around risks - including the effect on fertility, haematocrit monitoring, cardiovascular considerations, and the long-term commitment that TRT involves.
Regular monitoring - typically blood tests at 3 months initially, then 6-12 monthly once stable. Haematocrit and PSA monitoring are standard. Testosterone trough/peak levels are monitored to guide dosing.
A long-term treatment plan - TRT is typically a long-term commitment. A good clinic will have a clear framework for ongoing management rather than year-to-year prescribing without a plan.
Telehealth vs in-person for TRT in Australia
Telehealth consultations for testosterone therapy are available through several Australian clinics, and are appropriate for many patients following initial diagnosis. Initial diagnosis - particularly the first two testosterone measurements and baseline health assessment - is usually best done in person with a GP. Ongoing management can often be handled via telehealth for straightforward cases.
Clinics offering telehealth TRT management typically have a nurse or GP partner arrange local blood draws, with the prescribing doctor reviewing results remotely.
