Testosterone is a hormone often associated with masculinity. In males, the testicles make testosterone. In females, testosterone is produced in the adrenal glands, ovaries fat cells and skin cells. However, too little or too much of the hormone in both men or women can indicate severe health conditions.
What is testosterone?
In male bodies, T deepens the voice, puts hair on their chest and helps to produce sperm and maintain their sex drive.
Women also produce testosterone, but in smaller quantities. It maintains a hormone balance and helps to repair reproductive tissues, and bone mass.
T is also responsible for your mood.

What happens if testosterone levels are off?
High levels of testosterone can indicate a type of ovarian, or testicular cancer. On the opposite end, low T levels can indicate chronic illness.
It is important to note that some people have low levels of T, yet function at a “low normal” without any symptoms. This is according to Dr Rajiv Jayadevan, MD, assistant clinical professor of urology and male fertility expert at The Men’s Clinic at UCLA Health.
Low T in males often presents as one or more of the following symptoms:
- Enlarged male breast tissue (gynecomastia)
- Erectile dysfunction
- Reduced sex drive
- Overall tiredness, decrease in endurance
- Increased body fat
- Hair loss, including armpits and pubic hair
- Low (or zero) sperm count, causing male infertility
- Low muscle mass
Healthcare providers will often prescribe a testosterone tests for females with high levels of T. They often have symptoms including:
- Excess body or facial hair
- Deeper voice
- Acne
- Weight gain
- Irregular periods
- Decreased breast size

What is a Testosterone test?
A blood test is the most reliable way to test hormone level. Andrology expert, Charles Welliver, MD, advises people to skip the saliva tests: as this only measures free testosterone. Which makes up 2% of your total testosterone levels.
Even if your T levels are in range, yet you are experiencing symptoms, it is worth checking it out with your doctor. It might indicate an underlying issue.
People are required to prepare anything special ahead of a test. But your doctor will let you know if you need to follow specific instructions.
