The Gut-Reproduction-Oral-Immune Axis: Microbial Dysbiosis as a Shared Driver in Polycystic Ovary Syndrome and Endometriosis.
Review in Current microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Polycystic ovary syndrome (PCOS) and Endometriosis (EMs) are common reproductive endocrine disorders in women of reproductive age, characterized by the co-occurrence of infertility, chronic low-grade inflammation, and chronic pelvic pain. In this review, the “Gut-Reproduction-Oral-Immune Axis” (GROI axis) is introduced as a shared upstream pathophysiological mechanism for PCOS and EMs, with microbial dysbiosis playing a crucial role in its dysregulation. Despite distinct core pathologies, with PCOS characterized by metabolic/endocrine dysfunction and EMs by inflammatory/estrogen-dependent lesion formation, similar microbial dysbiosis patterns may drive disease pathogenesis via host-specific factors. Research indicates that patients with PCOS and EMs have common microbiota dysbiosis characteristics, such as lower alpha diversity (α-diversity), increased levels of Prevotella, decreased levels of Lactobacillus, although the specific patterns may vary by location (e.g., gut, reproductive tract, oral cavity) due to site-specific physiological niches. This type of dysbiosis participates in the disease process through the dysbiosis-brain axis mechanism in three aspects: disrupting the hypothalamic-pituitary-adrenal/ovarian (HPA/O) axis to cause neuroendocrine imbalance; activating the immune inflammatory pathway to lead to chronic low-grade inflammation; and inducing peripheral and central neural sensitization through pro-inflammatory factors and neuroactive substances. These mechanisms are interwoven, forming a self-reinforcing vicious cycle: microbial dysbiosis triggers the neuroendocrine-immune-pain cascade reaction, and the subsequent hormone disorders, inflammatory state and chronic stress further feedback to aggravate the microbial ecological imbalance. This article systematically expounds the common mechanism of the GROI axis in PCOS and EMs, providing a new perspective for understanding their shared pathological basis and developing intervention strategies targeting the microecology.
