What role does Leaky Gut Test play in Fruchtbarkeit?

The role of a 'leaky gut test' (intestinal permeability test) in fertility is not scientifically well-established. The concept of leaky gut refers to increased intestinal permeability, which has been linked to chronic inflammation and autoimmune conditions. Some commercial tests measure markers like zonulin, but their validity and clinical relevance for fertility issues are debated. There are no standardized, guideline-recommended tests for leaky gut in fertility diagnostics. Evidence is largely based on animal and mechanistic studies; large human RCTs are lacking. Anyone considering such a test should be aware that results cannot serve as a sole basis for treatment decisions. Instead, a comprehensive medical evaluation (e.g., by a gynecologist or reproductive specialist) is recommended. Marketing often overstates the scientific backing.
