What is testosterone?

Testosterone is the primary male sex hormone, produced mainly in the testes and, in smaller amounts, in the female ovaries and adrenal glands. It is a steroid hormone belonging to a group known as androgens, and plays a key role in many physical and reproductive functions in both men and women.

The main functions of testosterone:

  • Development of male sexual characteristics. Testosterone is responsible for the development of the male reproductive organs and secondary sexual characteristics, including voice changes, facial hair growth, increased muscle mass and a deeper voice.
  • Spermatogenesis. Testosterone plays a central role in the development and production of sperm, which is essential for reproduction.
  • Regulation of muscle mass and strength. Testosterone helps maintain muscle mass and strength, and is also involved in regulating body fat.
  • Influence on mood and behaviour. Testosterone can affect mood, energy levels, self-confidence and sexual drive.
  • Bone health. Testosterone contributes to maintaining bone health and bone density.

In women, testosterone plays an important role in regulating the reproductive cycle and has an influence on sexual drive and muscle mass. In both sexes, testosterone levels change over the course of a lifetime and can be affected by a range of factors, including genetics, age, lifestyle and overall health.

Low testosterone levels in men can lead to reduced sexual drive, fatigue, low mood and loss of muscle mass. In such cases, treatment to restore testosterone levels may be prescribed. Our doctors can carry out testosterone testing and address any concerns about deficiency.

Measuring testosterone levels

Testosterone testing is important for a number of reasons:

  • Diagnosing hormonal imbalances. Testing can help identify hormonal problems in both men and women. In men, low testosterone can cause reduced sexual drive, fatigue, low mood and loss of muscle mass. In women, elevated testosterone levels may indicate conditions such as polycystic ovary syndrome (PCOS).
  • Identifying the cause of sexual difficulties. In men experiencing problems with sexual function, including erectile dysfunction, testosterone testing may form part of the diagnostic process to help identify the underlying cause.
  • Monitoring treatment. Where testosterone deficiency has been diagnosed and replacement therapy prescribed, regular testing is important for tracking the effectiveness of treatment and adjusting dosage as needed.
  • Investigating irregular menstrual cycles in women. In women with irregular periods, testosterone testing may be part of the assessment to determine whether hormonal imbalance is a contributing factor.
  • Routine health monitoring. Testosterone testing may be included as part of a routine health check for individuals with risk factors for hormonal imbalance, such as obesity, diabetes or kidney problems.
  • Supporting athletic performance. Many athletes have their testosterone levels measured and supplemented, as testosterone supports muscle development, endurance, recovery and overall mood and wellbeing.
