Myths vs facts: Testosteron Test and Fruchtbarkeit

Myths vs facts: Testosterone test and fertility. A common myth is that low testosterone directly causes infertility. In reality, testosterone is essential for sperm production, but fertility depends on multiple factors: sperm count/motility, the entire hypothalamic-pituitary-gonadal axis (LH, FSH), genetics, and lifestyle. A single testosterone test (free or total) provides only a snapshot – levels fluctuate diurnally and are affected by stress, sleep, and diet. MyBody-X offers hormone tests that can measure testosterone, but these are marketed as lifestyle screening tools, not diagnostic for fertility. Fact: A testosterone test can offer clues, but a full fertility workup requires a semen analysis, comprehensive hormone panel, and clinical evaluation. Caveat: Low testosterone does not equal infertility; many men with low T father children. Evidence: practice (standard medical knowledge). Sources: None from context.
