What is considered a normal level of testosterone
What is considered a normal level of testosterone?

Even before birth, your testes start producing small amounts of testosterone. Levels increase throughout childhood and peak significantly during adolescence. By your early 20s, testosterone levels reach their highest point.

  • For adult men, a normal testosterone level ranges from 12 to 29 nmol/L.

  • These values do not account for age-related decline or individual symptoms, which your doctor will consider when interpreting your levels.

  • If your testosterone levels are less than 12 nmol/L and you have symptoms, you may benefit from testosterone replacement therapy (TRT) or alternative testosterone-boosting medications.

  • A 2022 study examined testosterone levels in 1,486 men aged 20 to 44. They determined normal testosterone levels for each age bracket by using the middle third of the data.
