Is it normal to have a grade 1 placenta at 37 weeks of pregnancy?

The 37th week of pregnancy is close to the delivery time, but there is still a certain amount of time before the delivery. However, due to the influence of many factors, premature delivery may occur. However, many pregnant women are very worried that delivery in this time range will have a negative impact on the health of the fetus. So, is it possible to get pregnant with a grade 1 embryo at 37 weeks of pregnancy?

The embryo bears the burden of exchanging the substances of the fetus and the pregnant mother. Through the network of blood vessels concentrated in the embryo, nutrients and oxygen are absorbed from the uterus and transmitted to the fetus through the umbilical cord; carbon dioxide and waste products in the fetus's body are released back into the mother's body. Therefore, the function of the placenta determines the growth and health of the fetus. If the placenta does not function properly, the adverse effects will be serious, and it may cause the fetus to grow slowly or even lack of oxygen.

Comments Placental function is a key research topic. Placental maturity can be divided into four levels: O, 1, 2 and 3. Grade 1 embryos are close to perfection, grade 2 embryos are already perfect, and grade 3 embryos are already fragile. Due to the thickening and fiber retention, the embryo's ability to absorb oxygen and nutrients is reduced, and the fetus is at risk.

The embryo of each pregnant woman is different. In the middle and late stages of pregnancy (12-28 weeks) - placenta grade 0; in the middle and late stages of pregnancy (30-32 weeks) - placenta grade 1; after 36 weeks - placenta grade 2 (more perfect). If the embryo is grade 3 and the fetal biparietal diameter is found before 37 weeks, the estimated baby weight is 2500 grams, which may be the maturity of the embryo. At 38 weeks, the embryo reaches stage 3, indicating that the placenta is mature. Generally speaking, at 37 weeks of pregnancy, the placenta functions at level 1, which has little impact on the fetus and allows for normal delivery.

Doctors use ultrasound to determine the maturity of the placenta, mainly based on the calcification points on the embryo. If the calcification points are scattered, it will be diagnosed as grade 2, and if the calcification points are connected, it will be diagnosed as grade 3. This is somewhat affected by subjective factors. Some doctors may see it as grade 3, while some doctors may only see it as grade 2.

We can judge by the strength of fetal growth, the amount of amniotic fluid of the pregnant woman, the frequency of fetal movement, the detection of fetal heart sounds, and the examination of fetal umbilical cord blood flow (Doppler color ultrasound). Especially the changes in the baby's fetal movements, every pregnant woman can observe it every day, which is a convenient and accurate method.

Generally speaking, at 37 weeks of pregnancy, the placenta is functioning at level one and is unlikely to have a major impact on the fetus. If there are no other reasons why you cannot choose natural birth, of course you can choose it.
