Is Leaky Gut Test useful for Fruchtbarkeit?

The usefulness of a 'leaky gut' test for fertility is not supported by strong evidence. The concept of increased intestinal permeability is linked to inflammation and autoimmune conditions, which may influence fertility, but the tests themselves (e.g., lactulose/mannitol challenge) are primarily research tools, not validated for clinical fertility assessment. Most commercial leaky gut tests lack rigorous validation and are often marketed with exaggerated claims. Current evidence does not show that measuring intestinal permeability directly improves fertility outcomes. For individuals trying to conceive, focusing on a balanced diet, stress management, and evidence-based fertility evaluations (e.g., hormone panels, ultrasound) is more appropriate. A leaky gut test is not recommended as a standalone fertility tool.
