Quick answer

Testosterone replacement is a prescription treatment for men with confirmed low testosterone (hypogonadism), shown on two morning blood tests along with symptoms. It can improve libido, energy and mood. It is not a treatment for erectile dysfunction alone and can reduce fertility.

What is testosterone used for?

  • Male hypogonadism (confirmed low testosterone with symptoms)
  • Delayed puberty in boys (specialist care)

How does testosterone work?

Testosterone replaces the hormone your body is not making enough of. It supports sex drive, muscle and bone strength, red blood cell production and mood. Taking it also signals the brain to reduce your own testosterone and sperm production.

How is testosterone used?

It is given as injections every few weeks, a daily skin gel, or capsules. Your doctor will choose the form and dose, then check your blood levels, blood count and prostate health regularly. Do not use testosterone for bodybuilding.
