Is Stuhlprobe useful for Fruchtbarkeit?

The question of whether a stool test (microbiome analysis) is useful for fertility must be answered cautiously from a scientific perspective. Currently, there are no robust clinical studies demonstrating that a commercial stool test can directly improve fertility or replace reproductive medicine. While the gut microbiome is associated with various health aspects, including hormonal processes, the causal link to fertility is weak and largely speculative. Most offerings on the market, including those from MyBody-X, are better classified as lifestyle or motivational tools rather than medical diagnostics. The evidence often relies on small studies or animal data, not randomized controlled trials in humans. Moreover, such tests are not validated for diagnosing or treating fertility disorders. Anyone experiencing serious fertility issues should consult a reproductive medicine specialist rather than rely on a stool test. In summary, the usefulness of a stool test for fertility is currently unproven, and the evidence is best described as marketing.
