Testosterone

Testosterone

This test measures testosterone levels, the principal androgen (male hormone) in men, and can also allow for the detection of hormonal imbalances related to symptoms of male andropause, rapid ageing, low vitality and sexual dysfunction.

In men

With advancing age, testicular function often declines and levels of free, bioavailable testosterone plummet. By the time a man reaches age 50, his bioavailable levels of testosterone may be half their youthful levels. The primary cause of this decline appears to be chronic deteriora tion of Leydig cells in the testes, but the decrease is also influenced by altered hypothalamic-pituitary-gonadal axis activity and age-induced changes in concentrations of sex-hormone binding globulin (SHBG)

In women

Imbalanced testosterone levels in women are also associated with a number of health complaints, including low libido, acne, hirsuitism and polycystic ovarian syndrome.

Testosterone powerfully influences:

  • Emotional well-being
  • Cardiovascular health
  • Sexual function
  • Bone integrity
  • Muscle mass and strength
  • Cognitive ability

Because of testosterone’s synergistic impact on immune, metabolic and inflammatory functions in the body, imbalances in the hormone may be found in a diverse array of health disorders, ranging from:

  • Rheumatoid arthritis
  • Obesity
  • Heart disease
  • Osteoporosis
  • Insulin resistance

What is being measured

Saliva testosterone levels

Salivary testing of hormones, unlike serum testing, measures the free, unbound fraction of hormone that is available to exert its effect on the target tissue. This test can be used to assess baseline levels and monitor testosterone replacement therapy.

Age range this test is suitable for

Adults. Younger adults must have gone through puberty.
