  1. Note: Participants from the healthy control group will be selected for metagenomic analysis and will only be assessed at the initial screening visit. History, biometric features, routine test results, and metagenomic analysis will be assessed. Biometric features include body mass index (BMI) and waist circumference; transvaginal ultrasound includes endometrial thickness, ovarian volume, antral follicle count, and size of ovarian cysts or developing follicles; Routine tests include blood routine examination, liver function, kidney function, routine stool, and urine tests; Hormone biomarkers include luteinizing hormone (FSH), follicle-stimulating hormone (LH), total testosterone, progesterone, estradiol, and leptin; metabolic biomarkers include fasting blood glucose (FBG), fasting insulin (FINS), homeostatic model assessment for insulin resistance (HOMA-IR), c-peptide release tests, total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL-C), and low-density lipoprotein (LDL-C); inflammatory biomarkers include C-reactive protein, interleukin-6, interleukin-18, and interleukin-22; questionnaires include Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS)
