Nutrition Intervention for Women With Polycystic Ovary Syndrome

The goal of this clinical trial is to evaluate whether different dietary models can improve clinical, metabolic, hormonal, anthropometric, and quality-of-life parameters in women with polycystic ovary syndrome (PCOS). The main questions it aims to answer are: * Do the Mediterranean Diet and the FertilOMed Diet (Fertility-Optimized Mediterranean Diet) lead to significant improvements in these parameters compared to the control group? * Does the FertilOMed Diet lead to greater improvements compared to the standard Mediterranean Diet? Study Description: This randomized controlled intervention study will be conducted between November 2025 and March 2026 at the Samsun Training and Research Hospital, Department of Obstetrics and Gynecology, Women's Health Outpatient Clinics. Necessary institutional permissions have been obtained for conducting the study at these sites. Participants: Women diagnosed with PCOS who meet the inclusion criteria and volunteer to participate will be included in the study. Interventions: Participants will be randomly assigned to one of the following groups: * Mediterranean Diet group * FertilOMed Diet group (Fertility-Optimized Mediterranean Diet) * Control group (standard dietary recommendations) Researchers will compare these groups to determine whether the dietary interventions improve clinical, biochemical, and symptomatic outcomes in women with PCOS.
