Currently, there are no effective specific treatments for PCOS. Therefore, identifying safe and effective therapeutic drugs for PCOS is clinically important.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this study, a PCOS mouse model was induced using dehydroepiandrosterone (DHEA) plus high-fat diet (HFD) to investigate the therapeutic effects of laurolitsine (LL). The efficacy of LL was evaluated by estrous cycle, glucose tolerance test (OGTT), insulin tolerance test (ITT), and serum biochemical markers. Histopathological analysis of ovarian, gonadal fat, and liver tissues was performed using hematoxylin and eosin (H&amp;amp;E) staining. Furthermore, RNA-seq analysis and 16S rRNA sequencing were performed to explore the potential mechanisms underlying LL\u2019s effects on PCOS mice.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      LL exhibited therapeutic effects in PCOS mice. LL improved lipid metabolism, glucose tolerance, insulin resistance, hormonal imbalance, and ovarian dysfunction in PCOS mice. RNA-seq analysis revealed that LL may improve PCOS by modulating key metabolic processes, including hormone response, fatty acid metabolism, and lipid metabolism in the ovaries. Additionally, LL significantly modulated the gut microbiota composition in PCOS mice, particularly reducing the abundance of\n                      <jats:italic>Proteobacteria<\/jats:italic>\n
