Normal estradiol levels during pregnancy

In fact, when it comes to estradiol, many friends may not be very familiar with this term. However, as a very important hormone in the female body, it has the function of promoting and regulating the normal development of female reproductive organs and secondary sexual characteristics. It is mainly secreted by the follicles after the ovaries mature. For such an important hormone in the body, what should be its normal value? What is the normal value of estradiol after pregnancy? Today we will mainly discuss this issue.

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.

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.

The amount of estradiol varies 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

Estradiol levels increase slightly during normal pregnancy and drop dramatically after the placenta is delivered. In abnormal twin or multiple pregnancies and pregnant women with diabetes, estradiol levels are generally elevated; in severe patients with pregnancy-induced hypertension, estradiol levels are lower. If estradiol levels are particularly low, it indicates the possibility of intrauterine fetal death, which should be confirmed in combination with other examinations for timely treatment.

What is the normal level of estradiol during pregnancy? This has been explained in detail above. Under normal circumstances, 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.
