About the Test

Testosterone is a male sex hormone that is produced by the testicles in men and in smaller amounts by the ovaries in women. It plays a key role in male sexual development, including the growth of the penis and testicles, the deepening of the voice, and the growth of facial and body hair. Testosterone also helps regulate bone density, muscle mass and strength, and red blood cell production. In addition, it is important for maintaining a healthy libido and overall well-being. Low testosterone levels can lead to decreased sexual function, decreased muscle mass, decreased bone density, and increased body fat. A blood test can be used to measure testosterone levels, and testosterone replacement therapy may be recommended for individuals with low testosterone levels.

Overview of Testosterone Blood Test

Testosterone is a male sex hormone that is produced by the testicles in men and in smaller amounts by the ovaries in women. It plays a key role in male sexual development, including the growth of the penis and testicles, the deepening of the voice, and the growth of facial and body hair. Testosterone also helps regulate bone density, muscle mass and strength, and red blood cell production. In addition, it is important for maintaining a healthy libido and overall well-being. Low testosterone levels can lead to decreased sexual function, decreased muscle mass, decreased bone density, and increased body fat. A blood test can be used to measure testosterone levels, and testosterone replacement therapy may be recommended for individuals with low testosterone levels.

Testosterone is made by:

  • The testicles (or testes), the part of the male reproductive system that makes sperm
  • The ovaries, the part of the female reproductive system that makes eggs
  • The adrenal glands, organs on top of each kidney that make several hormones

During male puberty, testosterone causes body hair, muscle growth, and a deepening voice. In adult life, it controls sex drive, maintains muscle mass, and helps make sperm. In females, testosterone is important for the growth of bones and muscles, and healthy organs.

Total Testosterone

A total testosterone test measures free testosterone and testosterone that’s attached to proteins. This is the most common type of test.

What Is a Testosterone Level Test?

A testosterone levels test measures the amount of testosterone in a sample of your blood. Testosterone is known as a “male” sex hormone, but females have testosterone in smaller amounts.

What Is This Test Used For?

A testosterone levels test may be used with other tests to help:

  • Diagnose the cause of symptoms that could be from testosterone levels that are too high or too low
  • In children and teens, to find out what’s causing:
    • Early puberty
    • Delayed puberty

Testosterone testing is also used to monitor your health if you:

  • Have had an abnormal testosterone test in the past
  • Are taking medicine that may affect your testosterone levels
  • Are a transgender man taking testosterone for masculinizing hormone therapy (also called gender-affirming hormone therapy)
Why Do I Need a Testosterone Level Test?

You may need this test if you have symptoms of abnormal testosterone levels.

For males who have gone through puberty, the test is mostly used for symptoms of low T levels (testosterone levels which are too low). Testosterone levels tend to decrease with age. But other health issues may also cause low T, such as thyroid problems, long-lasting illness, or problems with the testicles.

The symptoms of low T may include:

  • Low sex drive
  • Erectile disfunction or “ED” (difficulty getting an erection)
  • Infertility (difficulty getting someone pregnant)
  • Enlarged breasts
  • Lack of face or body hair
  • Thinning bones or anemia without a known cause
  • Loss of muscle mass

For females, the test is mostly used for symptoms of high T levels, such as:

  • Abnormal hair growth on the body or face
  • Hair loss on the head that may be like male-pattern baldness (hair loss at the temples and balding on the top of the head)
  • A voice that gets lower
  • Irregular or no menstrual periods
  • Infertility (difficulty getting pregnant)
  • Acne
How The Test Is Performed

A blood sample is taken from a vein. The best time for the blood sample to be taken is between 7 a.m. and 10 a.m. A second sample is often needed to confirm a result that is lower than expected.

How To Prepare For The Test

The health care provider may advise you to stop taking medicines that may affect the test.

How The Test Will Feel

You may feel a slight prick or sting when the needle is inserted. There may be some throbbing afterward.

Test Results

Normal Results

Normal measurements for these tests:

  • Male: 300 to 1,000 nanograms per deciliter (ng/dL) or 10 to 35 nanomoles per liter (nmol/L)
  • Female: 15 to 70 ng/dL or 0.5 to 2.4 nmol/L

The examples above are common measurements for results for these tests. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different specimens. Talk to your provider about the meaning of your specific test results.

What Abnormal Results Mean

Certain health conditions, medicines, or injury can lead to low testosterone. Testosterone level also naturally drops with age. Low testosterone can affect sex drive, mood, and muscle mass in men.

Decreased total testosterone may be due to:

  • Chronic illness
  • The pituitary gland does not produce normal amounts of some or all of its hormones.
  • Problem with areas of the brain that control hormones (hypothalamus).
  • Low thyroid function.
  • Delayed puberty.
  • Diseases of the testicles (trauma, cancer, infection, immune, iron overload).
  • Benign tumor of the pituitary cells that produce too much of the hormone prolactin.
  • Too much body fat (obesity)
  • Sleep problems (obstructive sleep apnea).
  • Chronic stress from too much exercise (overtraining syndrome).

Increased total testosterone level may be due to:

  • Resistance to the action of male hormones (androgen resistance).
  • Tumor of the ovaries.
  • Cancer of the testes.
  • Congenital adrenal hyperplasia.
  • Taking medicines or drugs that increase testosterone level (including some supplements).

Your test results may mean different things depending on which test was done, your age, your symptoms, the results of other tests, and other conditions you may have. So, it’s best ask your provider to explain your test results.

A testosterone level test alone can’t diagnose any health conditions, but abnormal results with symptoms may be a sign of a health problem.
