Glucose Metabolism and Live Birth Outcomes in PCOS

Oral glucose tolerance test with 75 g glucose (75 g OGTT) will be performed to those with normal fasting glucose and HbA1C levels. Women will be recommended to have normal diet for 3 days and overnight fasting for at least 8 hours. The blood withdrawal will be performed twice: (i) fasting and (2i) 2 hours after solution administration. The volume of blood for each test is 2 ml. Impaired glucose tolerance will be diagnosed when two-hour glucose levels of 140 to 199 mg/dL (7.8 to 11.0 mmol/l) (American Diabetes Association, 2018).
