Evidence check: Hormoncheck Männer in the context of Sport

A hormone check for men in the context of sports is often marketed as a tool to optimize training, recovery, or muscle growth. Typical markers include testosterone, cortisol, LH, FSH, and SHBG. The underlying biology is sound – hormones do influence athletic performance and recovery. However, the provided context contains no peer-reviewed evidence that such a check (especially as a DNA-based test) actually leads to improved sports outcomes. Hormone levels fluctuate significantly with time of day, diet, and stress; a single measurement has limited value. Genetic variants in hormone-related genes (e.g., AR, SHBG) generally have small effect sizes and lack clinical validation for athletes. The evidence is best described as 'marketing' or 'unclear'. Consumers should be cautious: without medical supervision and repeated measurements, a hormone check can lead to misinterpretation, unnecessary supplement purchases, or even risky self-medication. Lifestyle factors – sleep, nutrition, training load – dominate hormonal status far more than any single genetic variant.
