Lethargy, fatigue, reduced muscle mass and reduced libido— these can be the unpleasant consequences of a low testosterone level. Testosterone is the main male sexual hormone which regulates muscle growth and physical fitness.
Testosterone levels are highest in early adulthood and slowly decrease after the age of 30, which is due to a natural change of the blood levels. According to studies, testosterone decreases by one percent every year. You should therefore keep an eye on your testosterone levels.

Determine your blood concentration of the steroid hormone testosterone conveniently at home
Certain life stages, underlying diseases and medication can lead to a change in testosterone levels. Regular testing of your testosterone level is therefore important. Testosterone is the most important male sex hormone (androgen), however women also produce low amounts of testosterone. In men, it is produced in the Leydig cells of the testes. In women, it is produced in the Theka cells of the ovaries. In addition, a small amount of production takes place in the adrenal cortex in both sexes. The release of testosterone is controlled by what is known as the hypothalamic-pituitary-gonadal hormone axis. This testosterone is formed from cholesterol.
Please note that some drugs (e.g. hormone preparations) might influence the test result. For more information, please consult the FAQ.
