Impact of Diane-35 on Hormone Levels and Pregnancy Outcomes in Patients with Polycystic Ovary Syndrome: A Retrospective Analysis

This study confirms the significant efficacy of Diane-35 combined with metformin in improving hormone levels and pregnancy outcomes in PCOS patients, but it should be noted that retrospective design may have selection bias, short-term observation (12 months) limits long-term safety evaluation, and insufficient sample size limits subgroup analysis (such as differences in efficacy among different BMI stratification). Future multicenter prospective studies are needed for validation.
