What is the normal estrogen level?

After women enter puberty, their bodies will secrete large amounts of estrogen. From that point on, women's bodies will contain estrogen to maintain the normal development and growth of their bodies. However, the estrogen in a woman's body should also be kept within a normal range. If it is too high or too low, it indicates that there is some problem with the woman's body. So what are normal estrogen levels for women?

Normal values ​​of six estrogen test items

The normal values ​​of the six estrogen items are important indicators to measure whether estrogen is normal. The specific scope is as follows:

1. Follicle-stimulating hormone (FSH): promotes the development and maturation of ovarian follicles. Normal values: 1.5-10mIU/ml in the preovulatory period, 8-20mIU/ml in the ovulatory period, and 2-10mIU/ml in the postovulatory period.

2. Luteinizing hormone (LH): promotes ovulation, forms corpus luteum and secretes progesterone. Low FSH values ​​are seen during estrogen-progestin treatment, etc. Normal values: 2-15mIU/ml in the preovulatory period, 30-100mIU/ml in the ovulatory period, and 4-10mIU/ml in the postovulatory period.

3. Prolactin (PRL): It is a simple protein hormone that promotes breast hyperplasia, milk production and milk discharge. Normal value: During the non-lactation period, the normal value of blood PRL is 0.08-0.92nmol/L. A level higher than 1.0 nmol/L is considered hyperprolactinemia.

4. Estradiol (E2): Promotes the transition of the endometrium into the proliferative phase and the development of secondary sexual characteristics. Normal value: The concentration of blood E2 is 48-521nmol/L in the preovulatory period, 70-1835nmol/L in the ovulatory period, and 272-793nmol/L in the postovulatory period, indicating premature ovarian failure and Sheehan's syndrome.

5. Progesterone (P): Promotes the transition of the endometrium from the proliferative phase to the secretory phase. Normal value: Blood P concentration is 0-4.8nmol/L before ovulation and 7.6-97.6nmol/L in the late ovulation period, which is seen in luteal insufficiency, ovulatory dysfunctional uterine bleeding, etc.

6. Testosterone (T): About 25% is secreted by the adrenal cortex, and only 25% comes from the ovaries. Promote the development of the clitoris and mons pubis. Normal value: The normal concentration of T in female blood is 0.7-3.1nmol/L. High blood T value can cause infertility.
