Thus, the aim of the present study was to investigate the oral glucose tolerance test (OGTT), insulin sensitivity (Si), and acute insulin response (AIRG) during a frequently sampled glucose tolerance test (FSIGTT) as well as the interactions of age, body mass index (BMI), and waist-to-hip ratio (WHR) with the PCOS disorder in a relatively young group of women with PCOS. Here, INS is linked to polycystic ovary syndrome.
