How low will the progesterone level cause the fetus to stop growing?

Progesterone value is an important indicator for judging the condition of the fetus. Therefore, some people will be very worried when they find that their progesterone value is abnormal during the examination. They hope to know whether such a situation will cause fetal arrest. So, what is the lower the progesterone level during pregnancy, the more likely it is to cause fetal arrest? What is the lower the progesterone level during pregnancy, the more likely it is to cause fetal arrest? Let's have a simple understanding and understanding of this issue. I hope the following points will be helpful to everyone!

If the progesterone level is lower than what level, the fetus will stop growing

In fact, there is no accurate answer in clinical medicine at this stage. It is just that the lower the progesterone level, the greater the possibility of miscarriage, poor embryo development or fetal arrest. Therefore, do not blindly supplement with inappropriate products when you find that your progesterone level is low, otherwise the growth and development of the fetus may be affected due to improper eating.

What does progesterone value mean?

Progesterone is a component secreted by the embryo itself after a certain period of pregnancy. After the embryo is born, the corpus luteum will gradually secrete a certain amount of progesterone. This is a normal physiological process. Moreover, it is normal for the progesterone level to fluctuate in the early stage.

Therefore, some people find that the progesterone value tested today may be relatively low during the examination, but there may be a difference in the test tomorrow. This is considered normal. Therefore, when supplementing progesterone, you must ask the doctor to determine whether it is necessary to supplement it based on the actual development of your test tube embryo. Do not blindly supplement progesterone.

The progesterone level in women's bodies is produced by the ovaries, embryos and adrenal glands. During pregnancy, the level of blood progesterone increases steadily with the progress of pregnancy. In early pregnancy, it mainly comes from the corpus luteum of the ovary, and in the late pregnancy it is mainly secreted by the embryo. Progesterone is the key hormone to maintain pregnancy. It has the function of inhibiting the spontaneous contraction of uterine smooth muscle and reducing the tension of uterine smooth muscle, so that the uterus is in a static state before the pregnant woman gives birth.

Generally, at 5 to 6 weeks of pregnancy, progesterone is about 20-25ng/ml. From the perspective of progesterone alone, if progesterone is greater than or equal to 25ng/ml in early pregnancy, the probability of survival of the test tube embryo is high. If the level is lower than 15ng/ml, it indicates that the test tube embryo is incompletely developed, while if the progesterone level is lower than 5ng/ml, it generally indicates that the test tube embryo has stopped growing and developing. However, this is not certain and requires a comprehensive analysis combining the HCG elevation status, ultrasound results, etc.
