Body-Balance Check | Testosteron-Test: what are common causes?

Common causes of low testosterone are well-established in medical literature but not covered in the provided context. Key causes include: aging (testosterone declines ~1% per year after age 30), obesity and metabolic syndrome (adipose tissue converts testosterone to estrogen), sleep apnea, chronic stress (elevated cortisol suppresses testosterone), certain medications (opioids, glucocorticoids), and primary/secondary hypogonadism (e.g., testicular injury, pituitary disorders). A MyBody-X home test can measure current testosterone levels but cannot diagnose the underlying cause. Evidence for these causes is strong in clinical medicine („human-strong“), but the given context does not address them. Caveats: a single low reading should be confirmed by morning blood draw; results are influenced by time of day, diet, sleep, and medications. Without medical follow-up, the test may lead to misinterpretation or unnecessary supplementation.
