How To Qualify For Testosterone Replacement Therapy Australia: Doctor Criteria

Testosterone Takes Centre-Stage For Younger Australians

As of January 2026, a new, potentially dangerous trend has gained significant traction among young Australian males. It has been referred to by some as "testosterone-maxxing", a small part of a larger movement toward hyper-masculinity that has seen young men participating in increasingly dangerous and unhealthy behavior for several years.

This trend in particular sees young men consuming large amounts of "testosterone-boosting" foods and medications in the hopes of gaining muscle mass rapidly. However, the dangers of the trend are very real, and have prompted regulators to issue warnings regarding the use of unsanctioned testosterone products and even criminal indictments of some who were involved in their sale, as in the case of Queensland's own Michael Farrelly.

Critically, in the face of this movement, the team at Family Planning NSW is urgently raising awareness about the dangers of unnecessary testosterone therapy. As they suggested in a recent report, hormone therapy is most effective for those with "extremely low" testosterone levels. For anyone else, it may carry lifelong side effects and could result in permanent sexual dysfunction. As such, they suggest that anyone seeking testosterone replacement therapy should exclusively do so through the proper channels, such as a qualified therapy clinic.

Blood Tests Are The Gateway to TRT

Blood tests form the cornerstone of TRT eligibility assessment in Australia. Without pathology results, no reputable medical provider can determine whether testosterone replacement therapy is appropriate for an individual patient. These tests don't just measure testosterone levels - they provide a complete picture of hormonal health, organ function, and potential risks that could affect treatment safety.

The importance of thorough blood work extends beyond simple hormone measurement. Australian medical guidelines emphasise that TRT should only be initiated after clinical assessment, ruling out reversible causes of low testosterone. TRT Australia provides detailed guidance on the specific blood work requirements needed to determine eligibility for their treatment programmes.

As they explain, medical practitioners require these results to assess not only hormone deficiency but also liver function, kidney health, cardiovascular risk factors, and other safety markers. This approach ensures that testosterone therapy won't exacerbate existing health conditions or create new medical complications.

Two Pathways to Get Required Blood Work

Australian men have two distinct options for obtaining the necessary blood work for TRT evaluation. Each pathway has specific advantages and considerations that can impact both the speed of assessment and the testing quality.

1. Private Blood Work (Faster Processing)

Private blood work represents the most efficient pathway for TRT evaluation. This option typically provides faster processing times and ensures all necessary markers are included without the potential gaps that can occur with GP-ordered tests. Private pathology services specifically design their TRT panels to include every marker required for assessment.

The private route eliminates the risk of missing tests that could delay or prevent TRT approval. Many GP practices may inadvertently omit important markers from their standard hormone panels, potentially requiring additional testing rounds that extend the evaluation timeline. Private blood work addresses this concern by providing TRT-specific testing from the outset.

2. GP Blood Work Requirements

Obtaining blood work through a GP requires careful coordination to ensure all necessary tests are included. Patients must present their doctor with a list of required markers to avoid incomplete testing that could result in eligibility rejection.

GP blood work presents several challenges, including potential reluctance from some practitioners to order extensive hormone panels and the risk of incomplete testing. However, this pathway may be preferred by individuals who wish to work within the public health system or have established relationships with their family doctors.

What Blood Markers Determine Eligibility

TRT eligibility assessment requires analysis of multiple blood markers that provide insight into hormonal function, overall health, and treatment safety. Understanding these markers helps patients appreciate the thoroughness of the evaluation process.

Core Hormone Tests

Free and total testosterone levels form the foundation of TRT assessment, alongside Sex Hormone-Binding Globulin (SHBG) which affects testosterone bioavailability. Luteinising Hormone (LH) and Follicle-Stimulating Hormone (FSH) help determine whether low testosterone stems from primary testicular dysfunction or secondary pituitary issues.

Additional hormone markers include oestradiol (E2), prolactin, progesterone, and cortisol levels. These tests help identify underlying endocrine disorders that might be causing testosterone deficiency and could require different treatment approaches than testosterone replacement.

Additional Safety Markers

Safety assessment requires liver function tests (LFTs), kidney function markers (UEC), and lipid profiles including cholesterol, triglycerides, HDL, and LDL. These markers help identify potential contraindications to testosterone therapy and establish baseline values for ongoing monitoring.

Full blood count (FBC) provides information about red blood cell levels, as testosterone can increase haematocrit. Iron studies, glucose levels, thyroid function tests (TSH, FT3, FT4), and specialised markers like IGF-1 and DHEAS complete the assessment panel.

Australian Diagnostic Thresholds

For PBS-subsidised TRT, the criteria require consistently low morning total testosterone levels below 6 nmol/L on two separate tests, in conjunction with symptoms. Testosterone levels between 8-12 nmol/L (230-345 ng/dL) are considered borderline and require careful clinical correlation with symptoms.

Australian medical guidelines stress that testosterone levels must be consistently low across multiple measurements, as single low readings can occur due to various temporary factors including stress, illness, or medication interactions.

Medical Conditions That Block TRT

Several medical conditions represent absolute contraindications to testosterone replacement therapy in Australia. These conditions pose significant safety risks that outweigh potential benefits of treatment.

Absolute Contraindications

Prostate cancer and breast cancer represent absolute contraindications to TRT, as testosterone can stimulate growth of these hormone-sensitive cancers. Severe untreated sleep apnoea poses risks because testosterone can worsen breathing difficulties during sleep through neuromuscular and metabolic changes.

Uncontrolled congestive heart failure and haematocrit levels exceeding 54% also preclude TRT initiation. Additionally, recent stroke or heart attack, elevated prostate-specific antigen levels, and thrombophilia (blood clotting disorders) represent serious contraindications requiring careful medical evaluation.

Fertility Considerations

Men planning to conceive in the near future are generally advised to avoid TRT, as testosterone replacement can suppress natural sperm production through feedback inhibition of the hypothalamic-pituitary-gonadal axis. This effect can significantly reduce fertility potential during treatment.

Alternative treatments such as selective oestrogen receptor modulators (SERMs) or human chorionic gonadotropin (hCG) may be considered for men requiring testosterone support whilst maintaining fertility potential.

From Blood Work to Treatment Approval

Once blood work is complete, the approval process involves careful medical review and consultation to determine treatment appropriateness and develop personalised treatment protocols.

Upload and Review Process

Blood work results undergo a thorough review by qualified medical practitioners who assess hormone levels against Australian diagnostic criteria whilst evaluating safety markers for potential contraindications. Review timeframes can vary depending on the provider and the complexity of the case.

The review process encompasses not only hormone levels but also health assessment, including cardiovascular risk factors, liver and kidney function, and other markers that could affect treatment safety or effectiveness.

Medical Consultation Requirements

Following blood work review, eligible candidates proceed to a medical consultation where treatment options are discussed in detail. This consultation covers medical history, identifies potential causes of testosterone deficiency, and develops treatment plans tailored to individual needs.

The consultation process ensures patients understand treatment expectations, potential risks and benefits, monitoring requirements, and lifestyle considerations that can optimise treatment outcomes.

The TRT Journey Begins With Proper Blood Work

Understanding TRT eligibility requirements empowers Australian men to make informed decisions about testosterone replacement therapy. Blood work serves as the foundation for safe, effective treatment by identifying both hormone deficiency and potential safety concerns.

The evaluation process, whilst thorough, provides safeguards that protect patient health whilst ensuring appropriate treatment selection. Men experiencing symptoms of low testosterone benefit from understanding these requirements and working with experienced providers who prioritise both efficacy and safety.

Proper preparation for TRT evaluation, including blood work and honest medical disclosure, facilitates efficient processing and helps ensure the best possible treatment outcomes for eligible candidates.
