What are the treatment options for low testosterone?

A low testosterone result does not by itself explain symptoms. Levels change during the day and can be affected by illness, sleep, weight, medicines and other hormone problems. A GP consultation usually combines symptoms, examination and repeat testing at a suitable time.

The cause matters. Problems involving the testes, pituitary gland, long-term illness or certain medicines can require different care. A blood test may assess testosterone and related markers, while the clinician considers fertility plans and other health risks.

Where possible, treatment starts with the driver: reviewing an implicated medicine, improving sleep, managing a long-term condition, or addressing weight and nutrition with appropriate support. These steps may improve symptoms even when testosterone replacement is not suitable.

Testosterone replacement can be given in forms such as gels or injections, but it requires a prescription and follow-up. It is not suitable for everyone and can affect fertility, blood counts, the prostate or other conditions. Never use another person’s hormone medicine or non-prescribed products.

Book a review for persistent low libido, erectile difficulty, reduced energy, loss of muscle or fertility concerns, especially when several symptoms occur together. Seek urgent help for sudden severe headache, vision loss, chest pain, severe breathlessness or one-sided weakness.

Ask whether testing should be repeated, what may be causing the result, how treatment could affect fertility, which monitoring is needed, and what improvement would be a realistic treatment goal.
