Correlation of ovarian volume and clinical and laboratory parameters of PCOS in Korean patients

Abstract

Background: The aim of this study is to analyze the correlation of ovarian volume and clinical and laboratory parameters of polycystic ovary syndrome (PCOS) in Korean women. Methods: Two hundred and thirty-three patients aged between 20 and 40 years with PCOS diagnosis between January 2014 and June 2020 at Pusan National University Hospital, Busan, Republic of Korea, were included to this retrospective observational study using previously recorded patient medical charts. PCOS was diagnosed according to the revised 2003 Rotterdam criteria. Laboratory tests including anti-mullerian hormone (AMH), prolactin, thyroid stimulating hormone (TSH), follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, free and total testosterone, dehydroepiandrosterone-sulfate (DHEAS), 17-alpha-hydroxyprogesterone (17-OHP), HbA1C and insulin were conducted. Results: The correlation analysis showed that free testosterone (p = 0.006, r = 0.215), total testosterone (p < 0.001, r = 0.305), 17-OHP (p = 0.008, r = 0.203) and height (p = 0.008, r = 0.173) were statistically correlated with the total ovarian volume in overall PCOS patients. In these patients, serum AMH level was positively correlated with LH but negatively with body weight and body mass index (BMI). Conclusions: According to the results, the ovarian volume, quantified by ultrasonographic measurements, was significantly related to the increasing serum levels of free testosterone, total testosterone and 17-OHP in Korean PCOS patients.
