Normal progesterone levels during pregnancy

During pregnancy, many women pay more attention to the progesterone value, because we know that if the progesterone value is abnormal, it will have a great impact on pregnant women and will also affect the development of the fetus. When the progesterone value is abnormal, it is very likely to cause miscarriage. In order to reduce the occurrence of this accident, we must pay attention to it. When paying attention, we must first understand what the normal value of progesterone is. Let's take a look:

Progesterone reference value:

7 weeks of pregnancy: 52.7-100.1 nmol/L

8 weeks of pregnancy: 64.6-113.8 nmol/L

9-12 weeks of pregnancy: 78-159.2 nmol/L

13-16 weeks of pregnancy: 98.3-185.7 nmol/L

17-20 weeks of pregnancy: 153.8-241.2 nmol/L

21-24 weeks of pregnancy: 234.6-457.4 nmol/L

25-34 weeks of pregnancy: 403.4-626.2 nmol/L

After 35 weeks of pregnancy: 483.6-776.8 nmol/L

1. HCG begins to be produced after the active embryo implants, so measuring the blood HCG value is currently very important for confirming pregnancy.

2. Progesterone is another important hormone that ensures embryo implantation, immune regulation and maintenance of pregnancy. Is it necessary to test it? Is it reliable? Is it meaningful? Can low progesterone levels be improved?

Let’s discuss them one by one:

a. Is the measured progesterone value reliable?

Due to the pulsatile secretion of progesterone, the measured values ​​fluctuate widely, so the results are unreliable.

b. Is it significant?

As one of the indicators for diagnosing abnormal pregnancy, like the hCG test results, high progesterone levels indicate a high possibility of a normal pregnancy, while low progesterone levels indicate a high possibility of an abnormal pregnancy. It can only give patients the probability of a normal or abnormal pregnancy, but a specific value cannot confirm the outcome of the pregnancy.

c. Why is the progesterone level low? Can it be improved by increasing the dose or changing the dosage form?

Low progesterone levels are often caused by poor embryo development, so there is little point in supplementing it.

This is enough to prove the importance of normal progesterone levels for a pregnant woman. For some people who are not pregnant, abnormal progesterone levels will also affect a woman's fertility. If you suspect that your progesterone level is abnormal, you must seek medical attention in time and take medication to help improve your progesterone level, so that you can protect the fetus. If you want to know whether your progesterone level is normal, you should get a check-up in time.
