What is a normal testosterone level?

testosterone is a hormone, a substance that acts as a chemical messenger in the body. Hormones are produced in one part of your body and then travel to other parts to help control the way cells and organs work. Testosterone is important for your body to function properly. High or low testosterone levels can cause undesired symptoms.

Fortunately, it’s easy to determine if your testosterone levels are within the normal range. This article discusses normal testosterone levels, testing, and treatment.

What is testosterone?

Testosterone is a androgens hormones produced adrenal cortexThis testisand ovary.

This endocrine The glands produce hormones. Men produce hormones in the testes and women produce hormones in the ovaries.

testosterone and Estrogen are the two most well-known hormones. While testosterone is often considered the “male hormone” and estrogen is often referred to as the “female hormone,” they are present in both men and women. Both men and women can develop health problems if their testosterone levels are outside the normal range.

different types of hormones

Researchers have identified about 50 different hormones in the human body that control various processes such as hunger, mood, sexual function, metabolism, growth, and the menstrual cycle.

normal testosterone levels

Under normal conditions, testosterone performs many important functions in your body.

In men, hormones play a key role in:

  • sexual desire
  • sperm production
  • muscle and bone growth
  • Deepen voice and hair growth
  • development of male sex organs
  • mood

In general, health care providers consider normal testosterone levels in men to be between 300 and 1,000 nanograms per deciliter (ng/dL). These ranges may vary slightly depending on the standards used by your provider or laboratory.

Your testosterone levels may be higher or lower depending on your age, gender, medications, and other health conditions.

Testosterone production tends to slow down as a person ages.

female testosterone

Although women produce less testosterone than men, this hormone still plays a vital role in how women’s bodies function.

In women, testosterone helps:

  • bone strength
  • ovarian function
  • sexual desire

Normal testosterone levels in women are considered to be between 15-70 ng/dL.

Testosterone levels in men and women

Normal testosterone levels are often described as:

  • Male 300–1,000 ng/dL
  • Females 15–70 ng/dL

Men typically produce the most testosterone during their teenage years.

Symptoms of high or low testosterone

If your testosterone levels are too high or too low, you may start to notice changes.

Symptoms of high testosterone in men

Excess testosterone is not a common problem for men. However, men with too much testosterone may experience:

  • low sperm count
  • enlarged prostate
  • Myocardial damage
  • liver disease
  • acne
  • weight gain
  • high blood pressure or high cholesterol
  • fluid retention
  • Developmental delay (adolescents)
  • aggressive behavior or mood swings
  • headache
  • increased muscle mass
  • Higher risk of blood clots

Symptoms of low testosterone in men

Low testosterone is more common in men. This condition may cause the following symptoms:

  • breast enlargement
  • low libido
  • Difficulty getting an erection
  • low sperm count
  • fertility problems
  • fragile bones
  • irritability or difficulty concentrating
  • hair loss
  • frustrated
  • loss of muscle mass
  • fatigue
  • hot flashes

Symptoms of high testosterone in women

The correct balance between testosterone and estrogen is essential for the proper functioning of a woman’s ovaries.

Women with too much testosterone may experience a deep voice or smaller breasts.

One of the most common causes of high testosterone in women is a Polycystic Ovary Syndrome (PCOS), characterized by enlarged ovaries with small cysts.

Symptoms of high testosterone in women may include:

  • infertility
  • acne
  • irregular period
  • obesity
  • blood sugar problems
  • extra hair growth
  • male pattern baldness
  • depression or anxiety

Symptoms of low testosterone in women

Women can also suffer from testosterone deficiency, which can lead to:

  • fertility problems
  • Osteoporosis
  • low libido
  • vaginal dryness
  • breast changes
  • depression or difficulty concentrating


If your healthcare provider suspects that your testosterone levels may be too high or too low, they may recommend blood tests to measure the amount of the hormone.

Most testosterone in the blood is attached to two proteins, but some testosterone (called free or bioavailable testosterone) is not attached to proteins.

The two main types of testosterone blood tests are:

  • Total Testosterone: This test measures free and attached testosterone in the blood.
  • Free Testosterone: This test measures only free testosterone.

You may get tested in the morning (when testosterone levels are at their highest), but since testosterone levels fluctuate throughout the day, you may need to have multiple blood tests to confirm your levels.

Some studies suggest that saliva tests can also be used to accurately measure testosterone levels in the body.

Risks of a testosterone blood test

The risks of a testosterone blood test are small but may include:

  • bleeding
  • Blood stasis
  • Infect
  • mild pain
  • feeling dizzy

The Best Home Testosterone Tests


If you and your healthcare provider decide to treat low testosterone levels, you may be a candidate for testosterone replacement therapy (TRT). With this treatment, you’re actually replenishing your body with the testosterone it’s missing.

Testosterone comes in the following forms:

  • Oral capsule
  • gel
  • local solution
  • repair
  • injection
  • Implantable particles (implanted under the skin)
  • Intranasal Gel (Intranasal)

Your healthcare provider can help you determine the best testosterone formula for you.

Recent research shows that TRT use is increasing, with more than half of all testosterone prescriptions being written by primary care providers.

Treatment for high testosterone levels may include lifestyle changes, including exercise to improve symptoms.Healthcare providers can also prescribe anti-androgen drugs such as Lactone (Spironolactone), diabetes drugs such as action (pioglitazone), or oral contraceptives to help lower testosterone levels or relieve symptoms of high testosterone.

Risks of Testosterone Therapy

Some of the risks and side effects of TRT include:

  • possible risk of heart problems, cancer, and blood clots (although recent research suggests that all of these problems have low or possibly no risk at all)
  • infertility
  • Side effects such as breast enlargement (in men), skin reactions, changes in hair pattern, acne, and back pain


Testosterone is an important hormone for both men and women. If your testosterone levels are too low or too high, you may experience symptoms that affect your daily life. A simple blood test can help you determine if your levels are within the normal range, 300–1,000 ng/dL for men and 15–70 ng/dL for women. Treatment is available if you have abnormal testosterone levels.
