What is the normal progesterone level for pregnant women?

Many mothers are particularly worried about one issue when they are pregnant, that is, what is the normal progesterone value during pregnancy. Because they are worried that it will affect the baby, they are always anxious during pregnancy. In fact, there is a calculation range for progesterone values, so what is the normal value? Let’s learn about it together, and I hope everyone can gain something from my introduction.

It can produce enough progesterone from the 36th day of pregnancy. In the first three months: 5 plasma progesterone value is 0-15ng/ml, and the concentration in the serum of pregnant women is 1.5 in the fifth week of pregnancy, which increases to about 1.5 in the 32nd week of pregnancy, and reaches the highest peak of 150ng/ml in the 37th week of pregnancy, and it remains until the delivery, when it drops slightly.

First three months: Progesterone has no effect on the development of the child, but it affects the possibility of miscarriage. During normal pregnancy, a certain amount of progesterone hormone level is a necessary condition for maintaining pregnancy. In the early stages of pregnancy, the source of progesterone is the corpus luteum of 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. It also reduces the sensitivity of the pregnant uterus to oxytocin, reduces uterine contractions, and is beneficial for the growth and development of the fertilized egg in the uterus. If the progesterone level is insufficient, it will lead to threatened abortion or miscarriage.

Most authors at home and abroad agree that the serum progesterone level during the luteal phase (6-8 days after ovulation) or before 10 weeks of pregnancy is less than 100 mg/kg as the standard for luteal insufficiency [2gt;.

The detection of serum progesterone in early pregnancy is of great significance for the diagnosis and treatment of early threatened abortion. If the serum progesterone value is greater than 78nmol/L and the gestational sac is normal in B-ultrasound examination, the possibility of abortion is very small. At present, the units of conversion in various hospitals are different. If the reference value unit of the test report you get is ng/ml, it should be converted to nmol/L. Please pay attention to the unit.

3 weeks after menopause: 5 weeks -50mIU/ml#8226; 4 weeks after menopause: 5-426mIU/ml#8226;

5 weeks after menopause: 18-7,340mIU/ml#8226;

6 weeks after menopause: 1,080-56,500 mIU/ml#8226;

7-8 weeks after menopause: 7,650-229,000 mIU/ml#8226;

9-12 weeks after menopause: 25,700-288,000 mIU/ml#8226;

13-16 weeks after menopause: 13,300-254,000 mIU/ml#8226;

17-24 weeks after menopause: 4,060-165,400 mIU/ml#8226;

25-40 weeks after menopause: 3,640-117,000 mIU/ml#8226;

Postmenopausal women: <mIU/ml hCG less than 5mIU/ml is a negative reaction, not pregnancy, any amount over 25mIU/ml is a positive reaction, pregnancy. If pregnant, 85% of pregnant women, the amount of hCG in the blood doubles every two or three days. If hCG does not increase at this rate, it means pregnancy failure.

It is very important to observe your progesterone level during pregnancy, as it determines whether your baby is normal. If you find that your progesterone level is not up to standard, you must implement treatment in time to avoid accidents to the fetus and threatened miscarriage. If there are any adverse reactions, you must seek medical attention immediately.
