Symptoms
10 signs of low testosterone in men over 30
Testosterone levels can change with age and overall health. These symptoms can also have other causes, so they are a reason to discuss your health with a doctor rather than a diagnosis of low testosterone.
The classic ten
- Low libido — the single most predictive symptom.
- Erectile difficulty, particularly morning erections becoming rare.
- Persistent fatigue that sleep doesn't fix.
- Loss of muscle mass or strength despite training.
- Increase in body fat, especially around the waist.
- Low mood, irritability, or "flatness".
- Poor concentration or brain fog.
- Reduced motivation and drive at work.
- Sleep disturbance or feeling unrested.
- Hot flushes or sweats (less common, but distinctive).
Three or more = worth checking
Australian guidelines suggest investigating when several symptoms cluster. A two-minute screen like the ADAM questionnaire formalises this — and gives your GP something concrete to act on.
What's next?
If symptoms point that way, a bulk billed hormone blood test is the next step. Diagnosis is never based on symptoms alone.

The ADAM symptom check shows whether your symptoms may be worth discussing with a doctor. You can also request a callback to get matched with a men's health doctor at a partner clinic, by telehealth or in person, for an assessment.
