Relationship between angiopoietin-like-protein-2 levels and anti-mullerian hormone levels in polycystic ovary syndrome of reproductive age

Introduction: Polycystic Ovary Syndrome (PCOS) is the most prevalent metabolic disease affecting reproductive-age women and is often present with insulin resistance. Angiopoietin-like-protein-2 (ANGPTL2) is an angiogenic factor influencing insulin resistance in PCOS, manifesting in the anti-mullerian hormone (AMH). There are no previous studies regarding the relationship between ANGPTL2 levels and AMH in PCOS. The study aims to analyse the relationship between ANGPTL2 and AMH levels in PCOS and to compare ANGPTL2 and AMH levels between PCOS phenotypes. Methods: This cross-sectional study on 43 women aged 18-40 diagnosed with PCOS according to the Rotterdam criteria. Subjects were recruited consecutively and categorized into four PCOS phenotypes. Serum levels of ANGPTL2 and AMH were measured and analysed by correlation and comparison test using SPSS 26. Results: A total of 43 PCOS samples were included in the study within 4 months. Based on the severity, phenotype A (anovulation, hyperandrogenic and polycystic ovaries) showed the highest levels of ANGPTL2 and AMH. There was no significant difference in ANGPTL2 levels between the PCOS phenotypes. There was a significant difference in AMH levels between phenotypes, where the highest value was between phenotypes A and B. There was a positive correlation between ANGPTL2 and AMH levels. Conclusion: There is a positive relationship between ANGPTL2 and AMH serum levels. The ANGPTL2 serum levels were not significantly different. In contrast, the AMH serum levels significantly differed across the four PCOS phenotypes, with the highest level found in phenotype A.
