Evidence check: Hormoncheck Männer in the context of Darmgesundheit

The combination of a male hormone check with gut health is not well supported by current evidence. While the gut microbiome can influence hormone levels (e.g., testosterone) via the gut-brain axis and inflammatory pathways, direct DNA tests for male hormones in the context of gut health lack clinical validation. Most offered tests rely on GWAS data with small effect sizes or on general biomarkers like VDR or PPARGC1A, which have only indirect links to hormones and gut function. For reliable hormone assessment, blood or saliva tests (e.g., for testosterone, SHBG, cortisol) are far more accurate. Gut health should be evaluated separately through stool analysis (microbiome, inflammation markers) or symptom tracking. Be cautious of marketing claims: a 'hormone check for men' via DNA is not a substitute for medical lab diagnostics. The evidence level is 'unclear' or 'marketing'.
