Testosterone is a hormone that is produced naturally in the human body. It is responsible for the development of male sexual characteristics, such as the deepening of the voice and growth of facial and body hair.

Testosterone levels typically peak during adolescence and early adulthood. After age 30, most men experience a gradual decline in testosterone. A gel testosterona test measures the amount of testosterone in the blood.

Benefits of Using Gel Testosterone

Testosterone replacement therapy can have various positive effects, such as increased muscle mass and strength, improved mood and libido, increased bone density, and decreased body fat. Men who use testosterone gel may also experience side effects, such as acne, enlarged breasts, shrunken testicles, and an increased risk of heart disease.

How to Prepare for Getting a Gel Testosterone Test

No special preparation is needed for this test. You may be asked to remove clothing from the waist up and to wear a gown during the procedure.

What to Expect During a Gel Testosterone Test

A small amount of gel is applied to your skin, usually on your arm or shoulder. The area is then covered with a gauze pad or Band-Aid. A blood sample is taken from a vein in your arm using a needle. Afterward, the needle is removed, and the area is covered with a Band-Aid or gauze pad.

Interpreting Your Results

A gel testosterone test measures the amount of testosterone in your blood. The level of testosterone in your blood may be measured in nanograms per deciliter (ng/dL) or picograms per milliliter (pg/mL).

  • The normal range for testosterone is different for each laboratory. However, most laboratories consider a normal range to be between 300 and 1,000 ng/dL for men aged 19 years or older.
  • Lower than normal levels may indicate hypogonadism, which can lead to infertility, decreased sex drive, and impotence.
  • Higher than normal levels may indicate polycystic ovary syndrome (PCOS), testicular cancer, or adrenal tumors.

Who Should Get a Gel Testosterone Test?

Gel testosterone tests are generally ordered for men who have signs and symptoms of low testosterone levels, such as decreased sex drive, fatigue, and depressed mood. This test may also be ordered if you have any fertility concerns.

Difference between gel testosterone and other forms

1. Gel testosterone is applied directly to the skin, whereas other forms of testosterone are injected or taken orally.

2. Gel testosterone is absorbed into the body more slowly than other forms, so it may be less likely to cause side effects.

3. Gel testosterone may be more convenient to use than other forms, as it does not require injections or taking pills.

Gel testosterone is more effective because they are directly applied to the skin, and they work more slowly, so there is a decreased chance of side effects. Gel testosterone is also more convenient because you do not have to take pills or get injections.


If you are scheduled for surgery, you may have this test done to ensure that your testosterone levels are normal before surgery is performed.
