Usually, if the fasting blood glucose is 3.92~6.1mmol/L or 2-hour postprandial blood glucose is 5.1~7.8mmol/L, IVF transplantation can be carried out. If the blood sugar is too high or too low, it may cause IVF transplantation failure, so patients are advised to actively control their blood sugar within the normal range. The normal value of fasting blood glucose is 3.92~6.1mmol/L, and the normal value of 2-hour postprandial blood glucose is 5.1~7.8mmol/L. If the patient has blood glucose abnormality, it is not recommended to carry out IVF transplantation. If the patient’s blood sugar is not controlled in the normal range for IVF, it will reduce the chances of success of IVF, which may easily lead to embryo cessation of development or miscarriage. It is recommended that patients actively control their blood glucose, and if the blood glucose is too high, patients can improve their living habits to control their blood glucose, and use medication if necessary. It is recommended that treatment be carried out under the guidance of a doctor.
