Can Testosteron help with Müdigkeit?

Testosterone can help with fatigue if there is a confirmed testosterone deficiency (hypogonadism). Studies show that testosterone replacement therapy in men with low levels improves energy and quality of life. However, evidence for general fatigue without hormone deficiency is weak – testosterone is not an 'energy booster' for healthy individuals. In women, the data are even more limited and long-term safety is unclear. Moreover, uncontrolled use can cause side effects such as sleep apnea, increased cardiovascular risk, or mood swings. Therefore, a medical test (morning serum testosterone) and thorough evaluation of other fatigue causes (iron deficiency, thyroid, sleep disorders) are mandatory before therapy. Without a medical indication, testosterone administration is not recommended.
