PCOS (Polycystic Ovary Syndrome) of Bilateral Ovaries
Conditions
Brief summary
The purpose of the study is to understand the effect of Metformin on patients with PCOS.
Detailed description
This study aims to evaluate the effects of Metformin on reproductive endocrine and reproductive outcomes in women with PCOS, and to explore its underlying mechanisms to provide the intervention strategies for PCOS.
Interventions
PCOS patients were treated with metformin orally for 12 weeks, and various indicators related to fertility were observed.
