How much is estradiol in early pregnancy?

Generally, many female friends are not very familiar with estradiol, but as a very important hormone in the female body, it plays an extremely important role in the female reproductive organs and secondary sexual characteristics. Therefore, women must have some understanding of the normal value of estradiol hormone. So what is the estradiol level in the early stages of pregnancy? I hope that through my introduction, everyone can understand it.

1 The estradiol content is different in different periods of female life. Generally speaking, before puberty, the content is generally 0-121pmol/L; in the follicular phase, the content is approximately between 37-330pmol/L; during the ovulation phase, it becomes 367-1835pmol/L and in the luteal phase, it changes to 184-881pmol/L.

2 The level of estradiol also changes at different stages of a woman's ovulation period. Generally, it is 48-521 pmol/L in the preovulation period, 70-1835 pmol/L in the ovulation period, but changes to 272-793 pmol/L in the postovulation period.

3 The amount of estradiol will vary throughout pregnancy, rising slightly in normal pregnancy and dropping sharply after the placenta is delivered. In the early stage of pregnancy, it is generally 0-300 ng/L, in the middle stage of pregnancy, it is generally 1000-8000 ng/L, and in the late stage of pregnancy, it is generally 5000-27000 ng/L

Generally speaking, as long as there is no bleeding after pregnancy and the B-ultrasound shows that the embryo is developing normally, there is no need to delve too deeply into the specific content of estradiol. However, sometimes low estradiol levels are a precursor to certain serious diseases, such as ovarian dysfunction, premature ovarian failure, Sheehan's syndrome, etc., which require attention.

Experts remind that to check the normal value of estradiol, do not eat too greasy or high-protein food the day before blood drawing and avoid drinking large amounts of alcohol. The alcohol content in the blood will directly affect the test results. After 8 pm the day before the test, you should start fasting for 12 hours to avoid affecting the test results.

Estrogen stimulates the thickening of the endometrium in preparation for conception. If conception does not occur, the proliferating endometrium will shed and bleed to form menstruation. Low estrogen levels in the body can cause the endometrium to not grow thick enough and result in less menstrual bleeding, which can affect conception in the future. You should go to the hospital for a check-up to determine the cause of low estrogen levels and receive targeted treatment.

The above is some introduction to the normal values ​​of estradiol in early pregnancy. Generally, women often experience low estradiol levels in the early stages of pregnancy. Once this phenomenon occurs, timely treatment is necessary and should not be delayed. Otherwise, it will seriously affect the development of the fetus. It will also have a certain impact on women themselves, so you must pay special attention to it!
