What to watch with Leaky Gut Test and Fruchtbarkeit?

The concept of 'leaky gut' (increased intestinal permeability) is scientifically debated. Tests that measure permeability directly (e.g., lactulose/mannitol) are used in research but are not standard clinical tools for fertility. Commercial stool or saliva tests often lack validation for this purpose. Some evidence suggests that chronic low-grade inflammation, which can be linked to gut barrier dysfunction, may affect fertility through immune modulation or nutrient malabsorption. However, the evidence is mostly mechanistic or observational, not strong enough to recommend routine leaky gut testing for fertility. If you are trying to conceive, focus on a whole-foods diet, fiber, omega-3s, and lifestyle factors rather than a single test. Be cautious of expensive panels that may lead to unnecessary supplements. Always consult a reproductive specialist for fertility concerns.
