How mature does the placenta need to be before giving birth?

If a woman wants to know how long it will take to give birth after she becomes pregnant, she needs to judge the grade of the placenta. The placenta appears as the fetus grows and develops, and it is also the channel for nutrient exchange between the expectant mother and the baby. As the expectant mother's pregnancy progresses, the placenta is also gradually maturing. Only when the placenta matures to a certain level can the baby be safely delivered. So, at what level does the placenta need to be mature before birth?

First, at what level of maturity does the placenta need to be before birth? Generally, natural childbirth can be successful if the placenta is mature at level 1 or 2. Placental maturity level 1 means that the placenta is basically mature, and level 2 means that the placenta is already mature. It is normal to give birth at this time. However, if the placental maturity has reached level 3, it means that the placenta has begun to age and may pose a danger to the fetus. At this time, pregnant women should follow the doctor's instructions and take appropriate measures. The normal placental thickness is 3.6-3.8 cm on B-ultrasound, and generally does not exceed 5 cm. The membranous placenta is characterized by a large and thin placenta, which is prone to bleeding in the second trimester of pregnancy. If the placenta is small, it can lead to intrauterine growth retardation of the fetus and low birth weight at full term.

Second, simply looking at the thickness of the placenta does not make much sense. As long as there are no other problems during the prenatal check-up, there is basically no need to worry. In addition, placental thickness and placental maturity are two different concepts. If the placenta is too mature, you need to be vigilant. The nutrients needed for fetal development are obtained through the placenta, so the function of the placenta directly affects the health of the fetus. Expectant mothers should be alert to problems such as placental insufficiency in daily life to avoid fetal malnutrition or fetal hypoxia.

How mature does the placenta have to be before it can give birth to you? The placenta will gradually mature as the pregnancy progresses. When it matures to a certain degree, its function will decline, just like aging, and it will not be able to provide nutrition and oxygen to the fetus normally. The placental maturity grade is a standard used to measure the degree of placental maturity. It is usually divided into 4 levels, as follows: There are four levels of placental maturity: 0, 1, 2 and 3. Grade 0 indicates that the placenta is not yet mature: usually in the second trimester, around 12-28 weeks of pregnancy. Level 1 marks the early stage of placental maturity: 30-32 weeks of pregnancy, the early stage of placental maturity, can also transmit nutrients to the fetus. Level 2 indicates that the placenta is mature: generally after 36 weeks of pregnancy, the placenta is close to being mature. Level 3 indicates that the placenta has aged. Due to calcification and cellulose deposition, the placenta's ability to transport oxygen and nutrients is reduced, and the fetus is in danger at any time.
