Steroid Profiles in PCOS and Effect of OCP Treatment

The study enrolled 56 female patients aged 13-21 years with a diagnosis of PCOS according to Rotterdam criteria. At baseline, all participants underwent LC-MS/MS steroid profiling. A subgroup of 15 patients received oral contraceptive therapy based on clinical indication, independent of the study protocol. A second LC-MS/MS steroid analysis was performed at 6 months in this subgroup. The primary aim was to investigate the effect of OCP on the steroid biosynthesis profile. The study was approved by the Istanbul University Ethics Committee (Approval ID: 2019/822) and conducted between January 2020 and December 2021.
