Low testosterone is something many Australian men experience but rarely talk about, even though it can affect energy, mood and physical wellbeing. Testosterone naturally declines with age, but for some men it drops low enough to cause noticeable symptoms that are worth looking into.
This article explains what testosterone does, the common signs of low levels, and when it might be worth speaking with a GP or specialist. If you are ever experiencing a medical emergency, call 000 or go to your nearest emergency department straight away, rather than waiting for a routine appointment.
What Does Testosterone Do in the Body?
Testosterone is a hormone produced mainly in the testes, with small amounts also made in the adrenal glands. It plays a central role in men’s health, supporting muscle mass, bone strength, red blood cell production and sex drive.
It also influences mood, energy and concentration, which is part of why general information about hormone health explains that levels typically rise sharply during puberty and then gradually ease off from around age thirty onwards.
This gradual decline is normal and usually doesn’t cause problems. Low testosterone becomes more relevant when levels fall further than expected, or drop quickly, and start affecting how someone feels day to day.
Common Symptoms of Low Testosterone
Symptoms of low testosterone can be subtle at first and often overlap with other conditions, ageing, or simply a busy lifestyle. Still, a combination of the following changes is often worth mentioning to a doctor.
- Persistent tiredness or low energy that doesn’t improve with rest
- Reduced interest in sex or changes in sexual function
- Low mood, irritability, or difficulty concentrating
- Loss of muscle mass or reduced strength despite regular activity
- Increased body fat, particularly around the abdomen
- Trouble sleeping or noticeable changes in sleep patterns
- Thinning body hair or slower beard growth
None of these symptoms alone confirm low testosterone, since many can have other causes. That’s why testing and a proper conversation with a healthcare professional matters, rather than self diagnosing based on symptoms alone.
What Causes Low Testosterone?
Ageing and Natural Decline
For most men, testosterone falls slowly and steadily as part of normal ageing. This gradual pattern rarely causes major issues on its own, though some men notice symptoms more than others.
Underlying Health Conditions
Sometimes low testosterone relates to an underlying issue rather than age alone. This can include obesity, type 2 diabetes, chronic illness, certain medications, testicular injury, or problems with the pituitary gland, which helps regulate hormone production.
Lifestyle factors such as poor sleep, high stress, excessive alcohol use and low physical activity can also play a role. Healthy Male, Australia’s national men’s health organisation notes that these factors often act together rather than in isolation.
How Is Low Testosterone Diagnosed?
Diagnosing low testosterone usually starts with a conversation with your GP about symptoms, general health and medical history. Because testosterone levels naturally fluctuate, your doctor will usually want to understand the full picture rather than rely on one single sign.
A blood test is the main way testosterone is measured, and it’s often done in the morning when levels are typically highest. Depending on the results, your GP may repeat the test or check other hormones as well, following the sort of approach outlined in clinical guidance for GPs from the Royal Australian College of General Practitioners.
If needed, your GP can provide a specialist referral to an endocrinologist, a doctor who specialises in hormone conditions, for further assessment and ongoing care.
Treatment Options and Support
Treatment for low testosterone depends on the underlying cause, symptom severity and a person’s overall health, so there’s no single approach that suits everyone. Any decisions here should be made with a qualified, AHPRA-registered doctor rather than through self medication.
In some cases, addressing an underlying condition, such as improving diabetes management or reducing excess weight, can help testosterone levels recover naturally. In other cases, hormone therapy may be considered, prescribed and monitored by a GP or specialist.
Where medication is involved, cost can be reduced through the Pharmaceutical Benefits Scheme (PBS) for eligible prescriptions, and Medicare rebates may apply to eligible GP visits, blood tests and specialist appointments. Current rebate details and eligibility are best checked directly through Services Australia’s Medicare information, since amounts and rules can change.
Lifestyle Factors That Can Support Healthy Testosterone
Alongside any medical treatment, everyday habits can support overall hormone health and general wellbeing. These aren’t guaranteed fixes, but they’re generally good for men’s health regardless of testosterone levels.
Regular physical activity, particularly strength based exercise, a balanced diet, healthy sleep habits, and limiting alcohol intake are commonly recommended. Managing stress and maintaining a healthy weight can also make a meaningful difference over time.
Allied health professionals, including dietitians, exercise physiologists and psychologists, can offer practical, personalised support alongside your GP’s care, particularly if lifestyle changes feel overwhelming to tackle alone.
When Should You See a GP?
It’s worth booking a GP visit if you’ve noticed several symptoms that could suggest low testosterone, especially if they’re persistent or affecting your daily life, relationships or mental health.
Many practices offer bulk billing for eligible patients, and telehealth appointments have made it easier to start this conversation from home, particularly for men in regional or remote areas. For general guidance on medicines and treatment options, independent medicine information from NPS MedicineWise can also be a useful starting point before your appointment.
Remember, only a qualified healthcare professional can assess your individual situation, interpret test results accurately and recommend appropriate next steps for you.
Conclusion
Low testosterone is a common but often under discussed part of men’s health, and recognising the symptoms early can make a real difference to how it’s managed. From fatigue and mood changes to reduced muscle strength, these signs deserve a proper conversation rather than being brushed aside.
If any of this sounds familiar, consider booking a GP visit to talk through your symptoms and testing options.

FAQs
1. What is considered low testosterone for an Australian man?
There isn’t one fixed number that applies to every man, since normal ranges can vary between laboratories and depend on age and individual health. A GP interprets your blood test results alongside your symptoms and medical history, rather than relying on a single figure in isolation.
2. Can low testosterone be reversed naturally?
In some cases, addressing underlying factors like excess weight, poor sleep or high alcohol intake can help support healthier testosterone levels over time. However, results vary from person to person, so it’s best to discuss realistic expectations with your GP rather than assuming lifestyle changes alone will fully resolve things.
3. Is low testosterone the same as andropause?
The term andropause is sometimes used informally to describe age related hormone changes in men, similar to how menopause is described in women. It isn’t an official medical diagnosis in the same way, and the pattern of change in men is usually more gradual.
4. How much does testosterone testing cost in Australia?
Costs can vary depending on whether you’re bulk billed, which pathology provider is used, and whether a Medicare rebate applies to your specific test. For current, accurate figures, it’s best to check with your GP clinic or the Services Australia website rather than relying on a general estimate.
5. Can younger men have low testosterone too?
Yes, while low testosterone is more commonly discussed in older men, younger men can also experience it due to medical conditions, injury, certain medications or other health factors. If a younger man is noticing persistent symptoms, it’s still worth raising with a GP rather than assuming age rules it out.
