The gut-prostate axis describes the bidirectional communication between the Gut Microbiome and the prostate gland. Gut-derived microbial metabolites, inflammatory mediators, and immune signals influence prostatic health, while prostatic disease states alter systemic Metal-Driven Inflammation and, reciprocally, gut microbial composition.
Systematic review evidence supports gut microbiome involvement in benign prostatic hyperplasia (BPH), with specific taxonomic shifts—including enrichment of pro-inflammatory Proteobacteria and depletion of SCFA-producing Firmicutes—consistently observed across BPH cohorts ([1]Xu 2026 — The Gut-Prostate Axis in Benign Prostatic Hyperplasia: Systematic Review of Microbial Dysbiosis and Pathogenic MechanismsYuanzhao Xu, Lingyue An, Jiling Xie et al. · 2026Open reference 1 ↓).
The mechanistic pathways implicated include microbial translocation through a compromised gut barrier, systemic endotoxemia, and androgen metabolism by gut bacteria.
Separated gastrointestinal, non-taxonomic microbial, and normal bladder-neck/prostate component models for the emerging gut-prostate research domain. This reconstruction does not show translocation, a microbial signature, prostate disease, diagnosis, biomarker, or treatment response.

Therapeutic Implications#
Probiotic interventions targeting the gut-prostate axis have shown clinical benefit in chronic bacterial prostatitis, with randomized controlled trial evidence demonstrating reduced symptom scores and inflammatory markers ([2]Vocca 2025 — Probiotics in the Management of Chronic Bacterial Prostatitis: A Randomized, Double-Blind Trial to Evaluate a Possible Link Between Gut Microbiota Restoring and Symptom ReliefCristina Vocca, Diana Marisol Abrego-Guandique, Erika Cione et al. · 2025Open reference 2 ↓).
Broader reviews position the gut microbiome as both a preventive and therapeutic target across the spectrum of prostatic diseases, from prostatitis through BPH to prostate cancer ([3]Cao 2024 — Gut Microbiome: A Novel Preventive and Therapeutic Target for Prostatic DiseaseHongliang Cao, Difei Zhang, Pengyu Wang et al. · 2024Open reference 3 ↓).
