What is the normal value of progesterone small units?

After women become pregnant, the progesterone level in their bodies will be very high. If pregnant women go to the hospital for a check-up in the early stages of pregnancy, they must check whether the progesterone level is normal. If the progesterone level is abnormal, such as being significantly low, it may lead to early miscarriage. The progesterone level plays a vital role in normal pregnancy. If you go to the hospital to check the progesterone level, what is the normal result?

Normal value of progesterone small unit:

After pregnancy, expectant mothers often worry about the development of the fetus. Regular prenatal checkups can help doctors determine whether the fetus is normal. Progesterone is an important reference value for fetal development in early pregnancy. It has two sources. In the early pregnancy, it is secreted by the mother, and at 10 weeks of pregnancy, progesterone comes from the placenta and trophoblast cells. Progesterone will increase with the increase of gestational age, generally above 25ng/mL, and the value is multiplied by 3.18 to convert to nmol/L.

Before the placenta is formed, the hormones and nutrients needed for the fetus' growth and development come from the mother's secretions. Progesterone is a natural hormone secreted by the corpus luteum of the ovary. If progesterone is very low in early pregnancy, it will not be able to provide adequate nutrition to the fetus, which will lead to spontaneous abortion. This is why many doctors ask mothers to check their progesterone levels regularly during pregnancy. So what is the normal amount of progesterone? Let’s take a look at the following introduction.

Progesterone is secreted by trophoblasts and corpus luteum before 8-10 weeks of pregnancy, and is mainly secreted by the placenta after 8-10 weeks of pregnancy. Progesterone levels gradually increase during pregnancy, increasing slowly in the first trimester, accelerating in the second trimester, and reaching a peak at full-term pregnancy. Serum progesterone is stable during 5 to 12 weeks of gestation and has little to do with gestational age.

Here's how progesterone levels change after a woman becomes pregnant. For example, the reference value of progesterone (ng/mL) for pregnant women in the 1st to 3rd week is 4.7-50.7, and the reference value of progesterone (ng/mL) for pregnant women in the 4th to 6th week is 19.4-95.3. Generally speaking, it is necessary to check the progesterone level in the first three months of pregnancy, and pay attention to maintaining normal progesterone values ​​(≥25ng/ml). After the placenta is formed 3 months into the pregnancy, progesterone, which is the supplier of the placenta, will always remain rising. Therefore, you can ignore it after the placenta is formed. After 3 months of pregnancy, the progesterone secreted by the placenta can replace the ovaries to maintain pregnancy, and there is no need to inject progesterone to supplement it.

Progesterone is an essential nutrient for maintaining fetal development. Progesterone plays an important role in women, and both fertility and embryo development are related to progesterone. Low progesterone levels can lead to miscarriage, or even habitual miscarriage, which is very harmful to women's health and also causes huge psychological trauma. Progesterone helps stimulate changes in the uterus during the reproductive process and promotes embryo development by increasing blood flow to the reproductive system and tissues. If low progesterone occurs in early pregnancy, it may lead to miscarriage, so special attention should be paid during early pregnancy.

From the above, we know the important role of progesterone. If your progesterone level is low, you need to take dietary supplements or take some progesterone tablets. You can eat more foods rich in progesterone, such as corn and soybeans. However, the level of progesterone cannot fully reflect the quality of fetal development, and the progesterone value will fluctuate to a certain extent in early pregnancy. The status of the fetus cannot be determined solely from changes in progesterone levels.
