Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Polycystic Ovary Syndrome is kind of disease with unclear etiology. Recent studies on intestinal microbiota have raised the possibility that dysbiosis of intestinal microbiota maybe a novel theory for the development of Polycystic Ovary Syndrome. Hence, the investigators will compare the intestinal microbiota composition and diversity in PCOS with age, BMI-matched control and then assess whether intestinal microbiota modification is associated with clinical and biological parameters.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The goal of this study is to investigate and compare the composition of the intestinal microbiota in patients with PCOS and age, BMI-matched control. In addition, the investigators will investigate the relationship between alterations in the intestinal microbiota, clinical phenotype, biochemical analysis, body composition, inflammation and food consumption habit. The investigators hypothesize that alterations in the intestinal microbiota are associated with increased immune activation and progression of PCOS. Based on this hypothesis, the investigators propose the following aims:

Aim 1. Identify and enroll cohort with PCOS and age, BMI-matched control to study the role of intestinal microbiota on the development of PCOS.

1. Enroll participants at Drum Tower Hospital. Identify and classify participants through initial clinical evaluation, collect clinical metadata, obtain and process blood and stool samples for analysis.
2. Characterize the intestinal microbiota through quantitative PCR and high throughput sequencing analysis of stool specimens in participants.

Aim 2. Compare sequencing results and metagenomic analysis for study groups with particular attention to bacterial composition and metabolic capacity associated with energy harvest, lipid and carbohydrate transport, enhancement of epithelial barrier integrity and systemic inflammation.

3. transvaginal ultrasound with polycystic ovaries.

Exclusion of common medical disorders (normal thyroid function tests and serum prolactin and exclusion of 21-hydroxylase deficiency).
