What is a normal progesterone level?

We are all very concerned about some of the physical indicators of pregnant women, among which the progesterone value is a very important one. But many times people are not very interested in this value, and of course they don’t know much about it. In order to better protect the health of pregnant women and fetuses, we need to know some knowledge in this area. First of all, we need to understand the normal value of progesterone. So what is a normal progesterone value? Let’s see how the editor answers this question.

We all know that a sufficient level of progesterone hormone is necessary to maintain pregnancy. High concentrations of progesterone have a significant calming effect on the enlarged uterus and are very important for supporting early pregnancy. Progesterone can relax uterine muscle fibers and reduce excitability. At the same time, it can reduce the sensitivity of the pregnant uterus to oxytocin, reduce uterine contractions, and facilitate the growth and development of the fertilized egg in the uterus. Insufficient progesterone levels may result in threatened miscarriage or miscarriage.

Methods/Steps

1. Normal reference value of progesterone:

HCG (IU/L) in weeks of pregnancy

0.2-1 week 5-50

1-2 weeks 50-500

2-3 weeks 100-5000

3-4 weeks 500-10000

4-5 weeks 1000-50000

5-6 weeks 10,000-100,000

6-8 weeks 15,000-200,000

February-March 10,000-100,000

Only after understanding the normal value of progesterone can we better protect the health of the mother. We need to provide nutritious food to the mother so that the child can get adequate nutrition. We also need to do physical exercises for pregnant women seriously so that the children can grow better.
