Polycystic ovary syndrome is a complex neuroendocrine and metabolic disorder extending beyond ovarian health. Current standard treatments frequently fail to address ongoing challenges including chronic inflammation, infertility, metabolic dysfunction, obesity, and mood disorders. An evaluation of research published between January 2010 and May 2026 explores a therapeutic approach targeting the gut, brain, and ovary axis. This approach synthesises evidence regarding autonomic dysfunction, gut dysbiosis, and systems biology to propose a dual intervention strategy. By combining vagus nerve stimulation with targeted alterations to the gut microbiome, this framework aims to restore neuroendocrine, immune, and metabolic balance. In particular, pairing noninvasive transcutaneous vagus nerve stimulation with personalised microbiome interventions provides a novel, precision medicine direction for managing the multifaceted pathobiology of polycystic ovary syndrome.
Polycystic ovary syndrome affects metabolic, reproductive, and psychological health, yet existing interventions leave many symptoms unresolved. Exploring noninvasive nerve stimulation alongside microbiome adjustments highlights an integrated, whole-body approach. This perspective helps advance healthcare toward precision strategies that treat interconnected bodily systems together rather than targeting individual symptoms in isolation.
This work outlines a conceptual framework for therapies combining noninvasive transcutaneous vagus nerve stimulation devices with personalised microbiome interventions. Intended users would be healthcare providers managing polycystic ovary syndrome. Because the strategy is presented within a literature review rather than tested in a direct clinical trial, the technology remains at an early conceptual stage of development.

Introduction: Polycystic Ovary Syndrome (PCOS) is a complex neuroendocrine and metabolic disorder, rather than just an ovarian condition. Standard treatments often fail to fully resolve persistent issues such as inflammation, infertility, metabolic dysfunction, obesity and mood disorders. This review explores a novel therapeutic synergy: Combining vagus nerve stimulation (VNS) with gut microbiome manipulation to target the pathobiology of PCOS. Methods: A comprehensive literature search across major databases (including PubMed, Scopus and Google Scholar) analysed studies from January 2010 to May 2026. The search focused on autonomic dysfunction, gut dysbiosis, inflammation, neuroendocrine reproductive control, vagus nerve physiology and systems biology approaches to metabolic and gynaecological health. Results: Synthesising these findings yielded a novel framework: Concurrently modulating the gut microbiota and vagus nerve activity can synergistically restore neuroendocrine, immune and metabolic homeostasis in PCOS patients. Conclusion: Co-targeting the gut–brain axis using noninvasive transcutaneous VNS alongside personalised microbiome interventions offers a promising direction for precision medicine. This combined strategy could significantly advance future PCOS management.
