Testosterone
Testosterone replacement is used for clinically confirmed deficiency with compatible symptoms, not for general energy, muscle gain or normal ageing alone.
Key points
- Diagnosis usually requires symptoms plus appropriately timed blood tests and assessment of the underlying cause.
- Treatment can suppress sperm production and fertility and can raise the red-blood-cell count.
- Testosterone gel can transfer through skin contact, so product-specific handling precautions protect partners and children.

What testosterone is used for
Testosterone may be used for confirmed hypogonadism as part of clinician-led hormone therapy. Symptoms alone do not establish deficiency, and treatment may not be appropriate when fertility is desired.
How it works
Testosterone activates androgen receptors in many tissues. Replacement aims to restore levels within a clinically appropriate range rather than exceed normal physiology.
Clinically meaningful forms
Gels, injections and other formulations differ in absorption, monitoring and handling. Gel application sites should be covered as directed, and accidental skin transfer should be prevented.
Important safety checks
Review fertility plans, blood count, prostate and breast health where relevant, sleep apnoea, heart or clotting history, urinary symptoms and interacting medicines. Ongoing monitoring may include testosterone level, haematocrit and condition-specific checks.
When to seek urgent care
Seek urgent help for chest pain, sudden breathlessness, one-sided leg swelling, signs of stroke, a severe allergic reaction or a prolonged painful erection. Report marked headache, flushing or worsening sleep-related breathing promptly.
