Can Leaky Gut Test help with fertility?

The question of whether a leaky gut test can help with fertility cannot be answered affirmatively based on the provided evidence. The context includes no direct studies linking intestinal permeability tests to fertility outcomes. While mechanistic hypotheses exist—such as systemic inflammation or nutrient malabsorption affecting reproductive health—no clinical validation supports the use of such tests for fertility. The only cited study (PMID:39641896) addresses SIBO and lactase activity, not fertility. Commercial leaky gut tests often measure markers like zonulin or actomyosin, but their relevance to reproductive health remains unclear. Patients should not rely on these tests and instead seek specialized medical evaluation for fertility issues. The evidence is rated 'unclear' due to the lack of robust clinical data. A healthy lifestyle and balanced diet may support general gut health but do not replace fertility-focused diagnostics.
