About this test

What is Testosterone?

Testosterone is a vital hormone produced primarily in the testicles in men and in smaller amounts in the ovaries and adrenal glands in women. It plays a key role in sexual development, physical characteristics, and overall health for both sexes.

Testosterone Function in Men

In men, testosterone is essential for the development of male reproductive organs and secondary sex characteristics such as:

  • Increased muscle mass
  • Growth of body and facial hair
  • Deepening of the voice
  • Maintenance of libido and sexual function

A testosterone blood test can help assess hormone levels in men experiencing symptoms of imbalance.

Role of Testosterone in Women

Though produced in much smaller amounts, testosterone in women helps regulate:

  • Bone density
  • Muscle strength
  • Libido and mood

Testing testosterone levels is beneficial for women experiencing hormonal concerns or symptoms such as fatigue or reduced sex drive.

When is Testosterone Testing Recommended?

A blood test to measure testosterone levels is used to diagnose and monitor various health conditions. In men, low testosterone levels may indicate hypogonadism, with symptoms including:

  • Decreased sexual desire
  • Erectile dysfunction
  • Persistent fatigue
  • Depression or mood changes

In women, elevated testosterone levels can be a sign of polycystic ovary syndrome (PCOS). Symptoms associated with PCOS may include:

  • Irregular menstrual cycles
  • Excess facial or body hair
  • Acne or oily skin
