Placental maturity level 3 at 37 weeks of pregnancy

As we all know, the fetus obtains the nutrients and oxygen it needs to survive through the embryo. If the embryo is found to be abnormal or fragile during the creation process, it will affect the growth and development of the fetus and even seriously endanger its life. Therefore, the maturity of the embryo is very important and expectant mothers should understand it. Is there a risk of placental maturity level 3 at 37 weeks of pregnancy?

Normally, placental maturity corresponds to gestational age. Mid-to-late pregnancy (12-28 weeks) - placenta level 0; late pregnancy (30-32 weeks) - embryo level 1; after 36 weeks - embryo level 2 (more complete).

The more perfect the embryo is, the better it is. It only needs to have a certain degree of placental maturity according to your stage of pregnancy, because the embryo is important in supplying nutrients to the fetus. An embryo that matures too early means that the placenta ages quickly, which can easily lead to insufficient oxygen supply to the fetus and even cause delayed growth and language development of the fetus.

By the late pregnancy, the embryo is basically complete. If the embryo is found to have reached stage 3 before 37 weeks of pregnancy, and combined with the value of the fetal biparietal diameter and the estimated fetal weight of 2500 grams, the expectant mother should be alert to embryo maturity. Therefore, there is a risk of grade 3 placenta at 37 weeks.

What is the basis for distinguishing placental aging?

1. Check whether the placenta grade exceeds the pregnancy month. Generally speaking, when pregnant women are close to full term, the placenta maturity will be level 2 or 3, which is normal. However, if the placenta reaches level 2 maturity around 20 weeks of pregnancy, or level 3 maturity around 35 weeks of pregnancy, it means that the placenta function is reduced. To determine whether the function of a placenta is reduced, which is often called "placental aging", the key is to see whether the growth and maturity of the embryo exceeds the gestational month.

2. Use B-ultrasound to check calcification points. Doctors can use B-ultrasound to determine the maturity of the placenta, mainly based on the calcification points on the embryo. For example, if the calcification points are scattered, they will be diagnosed as grade 2, and if the calcification points are connected, they will be diagnosed as grade 3. But this will be affected by subjective factors to some extent. Some doctors may see it as level 3, while some doctors may only see it as level 2.
