Is Leaky Gut Test useful for fertility?

Whether a leaky gut test is useful for fertility cannot be answered affirmatively based on current evidence. The concept of 'leaky gut' (increased intestinal permeability) is scientifically controversial, and no standardized, validated tests exist for routine clinical use. Most commercial tests measure markers like zonulin, actomyosin, or lipopolysaccharide-binding protein, but their reliability in diagnosing a 'leaky gut' is questionable. Even if increased permeability were present, a direct causal link to fertility problems is not supported by robust human studies. Chronic inflammation or autoimmune conditions can affect fertility, but whether a leaky gut test provides actionable information remains speculative. The evidence is largely mechanistic or from animal models, not from randomized controlled trials in humans. From an evidence-based perspective, the test is not recommended for diagnosing or treating fertility issues. Individuals should pursue comprehensive reproductive medicine evaluation instead.
