Risks and limits of Stuhlprobe Männer

Stool microbiome tests for men can provide insights into bacterial diversity, but their clinical utility is limited. These tests typically measure relative abundances of bacterial taxa, yet standardized reference ranges for healthy men are lacking. Diet, medications, and lifestyle cause short-term, highly individual fluctuations. A result indicating 'low diversity' does not necessarily imply disease risk—it may reflect normal variation. Gender-specific norms are virtually absent. Evidence for actionable recommendations (e.g., specific probiotics) from such tests is weak. Risks include overinterpretation, unnecessary supplement purchases, and delaying medical evaluation for genuine symptoms. MyBody-X itself states these tests are not diagnostic. In summary: stool tests can serve as a rough orientation but not as a basis for medical decisions.
