Myths vs facts: Body-Balance Check | Testosteron-Test and Fruchtbarkeit

The 'Body-Balance Check' or 'Testosterone Test' is often marketed as a key to fertility. Fact: Testosterone is only one piece of a complex hormonal puzzle. A single test, especially from saliva or a home blood sample, captures only a snapshot – testosterone fluctuates with time of day, sleep, stress, and diet. Fertility depends on many factors: sperm quality, ovarian reserve, thyroid hormones, prolactin, and more. A DTC test cannot diagnose; it only gives a rough indication. For anyone trying to conceive, a medical workup with multiple measurements and a semen analysis is essential. The evidence for such home tests is weak; they rely more on marketing than clinical validation. Moreover, false normal ranges can cause anxiety or misguided self-treatment. My advice: invest in a doctor’s consultation rather than a questionable home test.
