Doctor's answer:
At full term of pregnancy, the maturity of the placenta generally reaches grade III. The maturity of the placenta is divided into three grades: Grade I represents the early stage of placental maturity, with uniform echoes, which can be observed at 30-32 weeks of pregnancy; Grade II indicates that the placenta is approaching maturity; Grade III suggests that the placenta has matured.
