Testosterone is a hormone found in both women and men. Men have significantly more testosterone than women but it starts to decrease after the age of 30. Testosterone levels naturally decrease as a part of aging.

Some men have lower levels of testosterone due to aging or problems with the testicles, pituitary gland or brain. This is called Testosterone Deficiency Syndrome or Low-T. Symptoms of Low-T can include low sex drive, fatigue, decreased muscle mass or bone density, erectile dysfunction or depression. Learning more about what normal ranges look like, how to test your levels and what testosterone replacement therapy (TRT) may look like can all help in regulating normal testosterone levels in men.

Normal Testosterone Ranges by Age

Normal testosterone ranges in men vary depending on their age:

Early childhood: A male baby will produce 75-400 ng/dL of testosterone. By the time he’s 10 to 11 years old, he should test between 7-130 ng/dL.

Early teens: Boys aged 12-13 should have a level of 7-800 ng/dL and increase to 100-1,200 by the time he is 15-16

Late teens: By the time he is 17-18 an optimal testosterone level is between 300 and 1,200 ng/dL.

Adult: An adult man, older than 19, should have testosterone levels anywhere between 240 and 950 ng/dL.

How To Test Your Testosterone Levels

Testosterone levels are tested from a sample of blood or saliva. This sample is then run at a laboratory to test the level of testosterone in your blood. You can get this test fulfilled through your primary care physicians, Regenerative & Sports Medicine, or via an at-home test kit. The best time to test your levels is in the morning when your testosterone is the highest.

What is TRT?

If you think you could benefit from testosterone replacement therapy (TRT) or androgen replacement therapy, it’s good to know what to expect when looking into it. TRT is intended to treat Low-T and comes in various prescription treatments. Forms of TRT include gels, pills, injections or dermal patches to administer testosterone to the body. Injections are administered deep into the gluteal muscle and are available in two strengths, 100 mg and 200 mg.

Monitoring your testosterone range is simple and can help prevent future medical problems. Testosterone is a hormone responsible for regulating sex drive, sperm production, muscle mass, fat distribution, bone density and red blood cell production. When testosterone levels fall below a normal range it can affect a man’s energy, strength and vitality. Learning more about Low-T and testosterone replacement therapy can make you more comfortable finding a solution that works for you. Remember that lowering levels of testosterone is a natural part of aging so starting testosterone replacement therapy can be an indefinite process. Talk to your doctor about what treatment options would be best for you.
