End of summary

Formerly just a common hormone, over the past five decades, a veritable myth has developed around testosterone as a supposed miracle cure for men. Nowadays, testosterone and anabolic steroids are the most commonly used substances in the field of competitive sports. Even in recreational sports, the number of applications is likely to be considerable due to their easy availability. In many cases, however, there is no need for treatment for testosterone deficiency. Rather, factors such as overweight and an unhealthy, stressful lifestyle contribute to a rather low testosterone level. The temptation to acquire a hormone preparation with testosterone and take it without medical consultation seems to be the seemingly easiest way to achieve a powerful, defined physique. However, there are also natural methods to increase the body's own testosterone levels.

What is Testosterone?

Testosterone is by far the most important androgen, i.e., male sex hormone. It plays a crucial role in the development of the reproductive organs, sexual drive, and the expression of typically male attributes such as hair and beard growth, as well as a deeper voice. Additionally, it is known for its anabolic effect, promoting muscle growth. On athletes, it also has a performance-enhancing effect by stimulating the formation of red blood cells and supporting the regeneration of bones and cartilage. However, it is important to note that a high level of testosterone not only increases sexual desire but is also associated with increased aggression, irritability, and dominant behavior.

In the blood, testosterone is mostly bound to a transport protein called SHBG. Only about 1 to 2% of it is freely available and therefore effective.

Testosterone: Important for men and women

In men, testosterone is primarily produced in the testicles. In the female body, it is also produced, albeit in much smaller quantities, by the ovaries and adrenal cortex. For women, testosterone serves less as an end product and more as an intermediate stage for further transformations, such as into estradiol, a female sex hormone.

Does testosterone affect muscle building?

Indeed, testosterone plays a significant role in muscle building and is even considered a virtual miracle drug for the development of a six-pack and enduring potency in the fitness and bodybuilding scene. The anabolic, muscle-building effect of this hormone stimulates protein biosynthesis and thus promotes muscle growth. This is one of the reasons why it is often easier for men to build and maintain muscle mass than for women. Already in the 80s, this led to the use of artificially produced testosterone without androgenic effects, solely reduced to its anabolic effect, as so-called anabolic steroids in strength sports as a doping agent.

Fat loss possible through testosterone?

Testosterone plays a crucial role not only in regulating carbohydrate and fat metabolism but also in determining where and in what form fat accumulates in the body. A high, healthy level of testosterone has been proven to actively support effective fat burning. In fact, some studies even suggest that maintaining an appropriate testosterone level is essential for successful weight loss.

Conversely, a high percentage of body fat, especially visceral fat, has a detrimental impact on the body's testosterone levels. Abdominal fat is hormonally active and promotes the conversion of testosterone into estrogens, leading to a vicious cycle.

Signs and consequences of elevated testosterone levels

There are specific signs and consequences associated with an elevated testosterone level. For adolescent males, a testosterone level of 0.1 to 9.0 µg/l is considered normal during puberty, while in adulthood, the range is 3.6 to 9.0 µg/l. In females, the normal range is 0.06 to 0.50 µg/l during adolescence and 0.15 to 0.55 µg/l in adulthood.

A blood test conducted by a doctor can measure testosterone levels, especially when certain diseases or symptoms raise suspicions of a deficiency or overproduction of testosterone.

An excessively high testosterone level may be attributed to overactivity or, in the worst-case scenario, the presence of a tumor that stimulates hormone production in the testicles, ovaries, or adrenal glands. The "control center" of hormones, the pituitary gland, can also cause imbalances in hormonal levels.

An elevated testosterone level, whether due to illness or doping, poses significant dangers and can cause long-term damage. In addition to infertility, depressive moods, and reduced memory performance, the risk of heart failure, stroke, thyroid disorders, and the development of tumors, such as in the liver and prostate, also increases.

In testosterone doping, there is not only the risk of contamination of the substance but also the danger of drastic overdose. This can manifest, for example, in extreme acne and the development of female breasts in men, as excess testosterone in the body is converted into female hormones.

Increase testosterone levels

The prevalent cause of a low testosterone level is primarily age-related. From around the age of 40, the natural production of the hormone decreases in men, similar to how women experience lower hormone levels during menopause.

However, a low testosterone level can occur for various reasons much earlier. This could be due, for example, to damage in the testicles, ovaries, or adrenal cortex, leading to reduced hormone production. Serious illnesses, excessive alcohol consumption, obesity, rapid weight loss, and persistent stress can also contribute to decreased testosterone production. Symptoms of a low testosterone level in men include infertility, erectile dysfunction, fatigue, and lack of libido.

Since a testosterone deficiency is often an indicator of more severe diseases, a doctor should thoroughly investigate the cause of the deficiency instead of prescribing testosterone replacement therapy directly.

If diseases can be ruled out as the cause, excess abdominal fat, also known as visceral fat, excessive stress, or inactivity could be additional reasons for low hormone levels.

For instance, abdominal fat releases the enzyme aromatase, which can convert existing testosterone into a female hormone. This means that there are excellent methods to naturally and easily increase the natural testosterone level: Regular physical activities combined with a balanced diet, sufficient sleep, and a as stress-free as possible lifestyle can increase testosterone levels by up to 60%, thereby having positive effects on male vitality.

Conclusion

Testosterone undoubtedly plays a significant role in performance and muscle building. Therefore, a low testosterone level that can negatively impact athletic performance should be medically evaluated. Even though it may seem tempting to get testosterone prescribed by a doctor or even buy it online or from dubious gyms to build muscle faster and in larger quantities, this supposedly "easier" way is not recommended. Without a medically confirmed, treatable testosterone deficiency, supplementing the hormone carries significant and not to be underestimated risks. On the contrary, with regular exercise and a healthy lifestyle, the testosterone level in the blood can be increased, leading to an improvement in overall well-being and performance.
