Testosterone is well known as the most important male sex hormone, but only a few people realise that testosterone is also produced in women. Testosterone plays a key role in female sexuality as well as a beneficial role in maintaining energy levels, mood and motivation.

In men, testosterone stimulates the physical changes that characterize the adult male, such as genital development, growth of facial and pubic hair, deepening of the voice, an increase in muscle mass and growth in height. Throughout adult life, testosterone helps maintain sex drive, the production of sperm cells, male hair patterns, muscle mass, and bone mass. Testosterone is produced mostly in the testes and a small amount of testosterone is produced from the adrenal glands.

Testosterone production declines as men age, giving rise to what is known as Andropause or Male menopause. Unlike female menopause, Andropause is a slow and subtle process with various signs and symptoms such as fatigue, depressed mood, loss of sexual desire, impotency, loss of muscle mass, increase in fat mass, and many other manifestations generally attributed to aging. Testosterone deficiency can also be seen in young men when the adrenal glands are exhausted (adrenal fatigue) or when they are exposed to xenoestrogens (synthetic chemicals that act as estrogen in the body).

Testosterone can be checked in the blood (testing levels of free testosterone) or saliva to diagnose testosterone deficiency. Bioidentical Testosterone supplementation can help maintain a beneficial effect on energy, mood and sexual function. It also protects against obesity as well as preserving bone and muscle mass. Testosterone supplementation may also help decrease the risk of heart disease.

In women, testosterone is produced mainly from the ovaries and to a lesser extent from conversion of some adrenal gland hormones (mainly DHEA). Monthly surges of this hormone boost the sense of well-being, personal power and sex drive. Other benefits derived from testosterone are that it helps promote bone growth, and may relieve mild depression, some vasomotor symptoms, vaginal atrophy and dryness. As a substantial number of women experience diminished sexual interest and sense of well-being during their late reproductive years, or after surgery to remove the uterus and /or ovaries, supplementation with bio-identical testosterone have proven to be beneficial and help restore both their sexual interest as well as their sense of well being. Testosterone supplementation may play a role in protection from heart diseases and osteoporosis.

Bioidentical testosterone supplementation is similar in structure to the testosterone our body produces. In New Zealand, testosterone is a prescription only product however many practitioners may not be aware of it.
