What role does Testosteron play in Darmgesundheit?

Testosterone influences gut health through several mechanisms, including modulation of the intestinal barrier, the microbiome, and immune regulation. Animal studies show that testosterone can reduce gut permeability and dampen inflammatory processes. In humans, low testosterone levels in men are associated with a higher risk of metabolic syndrome and inflammatory bowel disease (IBD), but a direct causal role in gut health is not firmly established. There is also evidence for sex-specific regulation of the gut microbiome by sex hormones, with testosterone potentially affecting microbial diversity. However, clinical relevance remains unclear because most data come from observational studies with confounding factors such as diet, lifestyle, and comorbidities. Testosterone deficiency should be evaluated medically before any intervention. Overall, the role of testosterone in gut health is a promising but not yet well-evidenced area of research.
