Frequently Asked Questions About Testosterone
Why should I test my testosterone levels?
With a testosterone test, you can find out whether the level of the hormone is in a range that is normal for your gender and age group. For example, 40 percent of men over 40 do not have healthy testosterone levels - their values are too low. A testosterone deficiency can lead to decreased performance, fatigue, weight gain, and also to mood swings, hair loss, and erectile dysfunction.
And there is too little testosterone in younger people, typically as a result of being overweight, taking medication, and high stress.
So if you feel limp and tired, gain weight or even lose hair for no apparent reason, it may be due to an impaired hormone level. A testosterone test will tell you how you are doing with this hormone.
For athletes, testosterone values in the higher normal range make sense, as the hormone makes a significant contribution to the development of muscles and physical performance.
What Is Testosterone?
Testosterone is the most important male sex hormone. It is also found in smaller amounts in women's bodies. Men produce 90 percent of testosterone in the testicles, women in the ovaries, and in both sexes, it is also produced in the adrenal cortex. Like many other hormones, testosterone levels fluctuate constantly. The natural range of testosterone concentration in saliva is between 6.1 and 230.9 picograms per milliliter in men and between 3.1 and 50.2 picograms per milliliter in women.
How does the testosterone test work?
With the help of a small straw that came with the test kit, you can put some saliva in a collection tube. You fill three tubes this way in the course of a day. Then send the three samples in the return envelope to a specialist laboratory.
Note: You should take the test when you are healthy. Infections like cold or flu can falsify the results, as can alcohol consumption. Certain drugs and medicinal plants also influence values.
What does the results report tell me?
You will find out how high your morning testosterone level was and whether the values are within the recommended reference range. If the values are above or below, this is an indication of a testosterone excess or testosterone deficiency.
What recommendations do I get?
In the results report, you will find a number of recommendations that will help you normalize your testosterone levels. Among other things, you will receive tips on nutrition and exercise as well as on the connection between testosterone and vitamins and minerals. These recommendations can help you get your testosterone levels in the green
What do I need testosterone for?
As a sex hormone, testosterone is responsible for the formation of sperm and sexual pleasure in men. It also ensures that the male genitals of the fetus develop in the womb.
The hormone is also involved in other tasks in the body of men and women, including:
- building muscle mass
- body hair
- stability and growth of bones
- blood formation
What happens if there is a lack of testosterone?
Testosterone levels naturally decrease with age, especially in men, but can become too low for all age groups.
Possible causes are obesity, chronic stress, alcohol abuse, and diseases such as Addison's disease. In women, the hormonal changes during menopause sometimes upset testosterone levels. 1 in 10 men over the age of 50 also suffers from age-related testosterone deficiency, which is referred to as male menopause or andropause.
A testosterone deficiency can, among other things, lead to a decrease in muscle strength and physical performance, more belly fat, hair loss, and erectile dysfunction.
What helps with a testosterone deficiency?
A testosterone deficiency can be addressed with the following measures, for example:
- Sufficient sleep and exercise, especially strength training
- Reduce excess weight
- Optimized supply of vitamin D and the minerals magnesium, selenium, and zinc
- For certain diseases, drugs (anabolic steroids) and other testosterone-control measures
What happens if there is excess testosterone?
If the testosterone level is well above the normal values, this is usually an indication of external influences or diseases. On the one hand, syringes and tablets containing testosterone can be behind it, (for example, doping agents). The disease Cushing's disease, which is associated with elevated cortisol levels, can also cause excess testosterone.
In women, too much testosterone promotes, among other things, menstrual disorders, increased body hair and hair loss on the head, and a deeper voice.
In men, excess testosterone can reduce fertility - up to impotence - and lead to acne, hair loss, shrunken testicles, and enlarged prostate.
Therapy: If there is an excess of testosterone, it is usually important to treat the underlying disease.
Who is the test not suitable for?
The testosterone test is potentially not suitable for the following groups of people:
- People with infectious diseases such as hepatitis and HIV are not allowed to take the testosterone test.
- Pregnant and breastfeeding women should only perform the testosterone test under medical supervision. The reference values and recommendations do not apply to you either, so you should obtain recommendations on the test results from your doctor or therapist.
- The testosterone test is not suitable for children under 18 years of age .
- The test is also not intended to examine diseases. For example, if you have severe depression or extreme pain, contact a doctor.
