What role does Testosteron Test play in Darmgesundheit?

A testosterone test measures hormone levels in blood or saliva. Direct evidence for a role in gut health is lacking. Testosterone may indirectly influence gut function via immune modulation, motility, and microbiome composition – animal and small human studies suggest possible links, but the evidence is weak and not ready for clinical application. A hormone test alone does not assess gut health. For gut-related symptoms, specific diagnostics (stool analysis, calprotectin, colonoscopy) are more appropriate. Marketing testosterone tests as a 'gut health check' is misleading. Evidence: unclear/marketing.
