Brief Summary:
The goal of this observational study is to investigate the distinct tongue manifestation characteristics in patients with diminished ovarian reserve (DOR) compared to healthy individuals, and to clarify the features of tongue coating microbiota, gut microbiota, and their interrelationships in DOR patients. The main question it aims to answer is:
Whether there are significant differences in tongue manifestations, tongue coating microbiota, and gut microbiota characteristics between DOR patients and healthy populations; Whether associations exist between tongue coating microbiota and gut microbiota in DOR patients; Whether the pathogenesis of DOR may influence estrogen metabolism through alterations in oral and gut microbiota.
Whether there are significant differences in tongue manifestations, tongue coating microbiota, and gut microbiota characteristics between DOR patients and healthy populations; Whether associations exist between tongue coating microbiota and gut microbiota in DOR patients; Whether the pathogenesis of DOR may influence estrogen metabolism through alterations in oral and gut microbiota.
Detailed Description:
This study enrolled DOR patients and healthy women as controls to systematically analyze compositional differences in intestinal and tongue coating microbiota between the two groups. Using 16S rDNA sequencing technology combined with bioinformatics methods, we screened characteristic microbiota associated with DOR and identified microbial markers significantly correlated with serum estrogen levels (AMH, FSH) through Spearman correlation analysis. We further compared abundance differences of homologous bacteria between tongue coating and gut microbiota to determine whether DOR alters the abundance or prevalence of specific bacterial species by affecting tongue-gut axis microbial interactions. The potential of tongue-gut differential microbiota combinations as non-invasive diagnostic biomarkers for DOR was explored.
