Abstract: Background: PCOS is the most common endocrinological disorder affecting 6 -14% amongst reproductive age group. The pathophysiology of PCOS is complex and it is still not well understood. Many markers have been studied to correlate between homocysteine level and other clinical, metabolic and hormonal profile. Preliminary investigations indicate that in women with PCOS, serum biomarkers of cardiovascular disorders such as homocysteine are abnormal. Furthermore the interactions between homocysteine and PCOS, biochemical features such as obesity, insulin resistance and higher levels of androgen, have been researched and the potential determinant of this finding is still being explored. Aim and Objectives: We aim to determine association between hyperhomocysteinemia and PCOS. The objectives of this study is to evaluate and compare clinical, metabolic and hormonal profile in women of PCOS with normal homocysteine level with that of increased homocysteine level. Materials and Methods: This is a prospective observational study which will be performed in the department of obstetrics and gynaecology, AVBRH, DMIMS (Deemed to be University, Wardha), a tertiary care teaching hospital situated in the rural area of Wardha district in over 140 patients for period between 2020-22. This study will include PCOS patients based on Rotterdam diagnostic criteria and will exclude patients with known metabolic, cardiovascular and endocrine disorders. Metabolic and hormonal profile will be evaluated with BMI, Lipid profile, Insulin resistance, serum levels of LH, FSH, DHEA and Testosterone in all patients. Serum homocysteine levels will be measured using ELISA. Expected Results: We expect that there will be significant difference in clinical, metabolic and hormonal profile of PCOS women having hyperhomocysteinemia than women having normal homocysteine level.
