Reference table of normal estradiol values ​​for women

We know that the body's estradiol levels rise during pregnancy, but estradiol levels vary at different stages. Next, I will share with you the reference table of standard values ​​of estradiol during pregnancy.

Pregnancy estradiol standard value reference table

Estradiol is a hormone secretion substance. It is a hormone drug secreted by the female uterus and ovaries. It is an important estrogen, and the standard value of estradiol during pregnancy is not fixed.

The efficacy of estradiol depends on regulating female characteristics, the perfection of attached reproductive organs and its control of menstrual and ovulation cycles.

The normal value of estradiol will change differently at different stages, and for each person, the normal value of estradiol will also be different.

The reference table for standard values ​​of estradiol during pregnancy is:

0~300ng/L in early pregnancy.

1000~8000ng/L in the middle and late stages of pregnancy.

5000~27000ng/L in the middle and late stages of pregnancy.

Causes of low estradiol during pregnancy

1. Threatened abortion

In the early stages of pregnancy, the progesterone level should remain elevated, but when a pregnant woman has symptoms of miscarriage, the progesterone level will decrease.

2. Ectopic pregnancy

A decrease in progesterone in pregnant women may also be caused by ectopic pregnancy, and regular blood HCG tests and B-ultrasound examinations should be conducted for further diagnosis. What is the progesterone value for ectopic pregnancy: Clinically, it is believed that when the progesterone level is higher than 20ng/ml in the early stages of pregnancy, ectopic pregnancy can be ruled out. But when the progesterone level is less than 10ng/ml, it is very likely to be an ectopic pregnancy and further examination is needed to confirm.

3. Adrenal and thyroid hormone imbalance

Pregnant women with physical illnesses can also cause a decrease in progesterone, such as a serious imbalance of the adrenal glands and thyroid hormones, which can affect the ovaries of pregnant women, causing insufficient corpus luteum secretion in the ovaries, and the progesterone content will also decrease accordingly, but relatively speaking, it will be less.

What are the effects of low estradiol during pregnancy?

If the estradiol level is low, it will have a great impact on the early pregnancy. Estradiol is the female hormone. If it is relatively low, it will cause incomplete villus development of the embryo, which is very likely to cause premature birth or miscarriage. Therefore, the drug must be used under the guidance of a doctor.

What to do if estradiol is low during pregnancy

On the sixth day of fertilization, the germ cells of the combined sperm and egg produce and secrete a small amount of hCG. On the 7th to 8th day of fertilization, hCG can be detected in the blood. Its concentration value doubles with the increase of pregnancy weeks. The secretion volume increases rapidly in the early pregnancy, doubling every two days, reaching a peak at 8 to 10 weeks, and then slowly decreases after 1 to 2 weeks. Dynamic monitoring of blood HCG changes is necessary to distinguish the status of embryonic development.

If ultrasound shows that the embryo is developing normally, there is no need to perform a preliminary test of estradiol in the blood as an indicator of embryo development. It should be added that Bujiale, which can be taken under the guidance of a doctor, is a natural estrogen.
