Testosterone is a male sex hormone, although women have it in smaller amounts. Statistics indicate that men make approximately 20-30mg daily with women making 2-3mg daily. Testosterone is primarily produced in the testes by males and is at its peak during the 20’s and 30’s and thereafter a slow decline may occur, which becomes more apparent after the age of 50.
In females testosterone is made in the ovaries and in the adrenal cortex of both sexes. To a lesser extent it can also be made in the skin, brain and liver. As with all hormones it starts from cholesterol through Pregnenolone then diverts through the androgen pathway to DHEA then Testosterone. Testosterone can further cascade into Oestradiol one of the Oestrogens through a process called aromatosis.
Why Is Testosterone So Important To Measure?
Testosterone helps to slow the ageing process through maintaining muscle mass and bone mineralisation. It has a positive effect on heart muscle and has been shown to reduce the risk associated with atheroscleosis, (plaque build-up in the arteries) It also works with emotional wellbeing, helping to maintain motivation and enthusiasm for living. Its most widely acknowledged effect is on supporting libido and sexual function. While this is more readily accepted with men the same can be true for women as Testosterone has been effective in treating vaginal dryness, thinning of vaginal tissue and increasing sensitivity in the genitals and breast tissue.
The ability to produce Testosterone is partly genetic so that in many cases, it’s “like father, like son.” We also know that lifestyle plays a role and men, who are overweight, smoke and/or drink alcohol excessively, will have lower levels of testosterone. Add to this the fact, that, as a man ages, not only does the production of Testosterone diminish, but so does the ability of his tissues and cells to respond to Testosterone.
A man who has previously had high levels of Testosterone throughout his younger life may find that although his Testosterone levels are still within normal range he is experiencing symptoms of Testosterone deficiency. This is because the testosterone levels are much lower than they used to be and he is sensitive to the decreasing levels.
What Are The Key Symptoms of Testosterone Deficiency?
- Reduced libido
- Abdominal fat
- Increased glucose and insulin levels
- Decreased muscle mass
- Reduced rate of growth of facial and body hair
- Loss of motivation
- Aches and pains
- Skin issues
What Does The Testosterone Test Involve?
Free Testosterone is measured via a non-invasive sample which is a convenient home salivary collection that evaluates free testosterone. With this test you are required to collect 1x saliva sample as soon as you wake up.
What Can I do with the test results?
Upon receiving your results, you may consult with a team member from Lab Tests Direct who can provide suggestions for a treatment plan and possible testosterone therapy.
