Haven’t you ever measured the normal values ​​of the seven sex hormones?

For women who have passed puberty but still have acne on their faces, it is best to check the seven sex hormones to see if your endocrine system is out of balance. Endocrine disorders can not only cause various skin problems, but may also cause menstrual disorders, which are more harmful to women's bodies. The only way to diagnose whether there is an endocrine disorder is to check the seven sex hormones of women. So what are the seven specific sex hormones? What is the normal value?

1) Luteinizing hormone (LH): Luteinizing hormone and follicle-stimulating hormone mainly promote follicle pain and ovulation. If the test value is too high, it may cause amenorrhea or infertility.

*The concentration of blood LH is 2-15mIU/ml in the preovulatory period, 30-100mIU/ml in the ovulatory period, and 4-10mIU/ml in the postovulatory period. The normal value during the non-ovulation period is generally 5 to 25 mIU/ml.

2) Follicle-stimulating hormone (FSH): It is a glycoprotein hormone secreted by the alkaliphilic cells of the anterior pituitary gland. Its main function is to promote the development and maturation of ovarian follicles.

*The concentration of blood FSH is 1.5-10mIU/ml in the preovulatory period, 8-20mIU/ml in the ovulatory period, and 2-10mIU/ml in the postovulatory period. Generally, 5 to 40 mIU/ml is considered normal.

3) Prolactin (PRL): High levels of prolactin may be caused by pituitary tumors and hypothyroidism.

It is secreted by the lactating trophoblast, one of the eosinophilic cells in the anterior pituitary gland. It is a simple protein hormone whose main function is to promote breast hyperplasia, milk production and milk discharge.

*The normal value of blood PRL is 0.08～0.92nmol/L. (During non-lactation period)

4) Progesterone (P): If the progesterone level is too low, it indicates hypofunction of the pituitary gland and ovaries, absence of menstruation or ovulation, and abnormal pregnancy;

*The blood P concentration is 0-4.8 nmol/L before ovulation and 7.6-97.6 nmol/L after ovulation.

5) Estradiol (E2): Ovarian tumors or pregnancy may indicate that estrogen levels are too high. If the estrogen levels are low, it may be caused by dysplasia, hypofunction of the pituitary gland and ovarian failure.

It is secreted by the ovarian follicles. Its main function is to promote the transition of the endometrium into the proliferative phase and promote the development of female secondary sexual characteristics.

*The concentration of blood E2 is 48-521 pmol/L in the preovulatory period, 70-1835 pmol/L in the ovulatory period, and 272-793 pmol/L in the postovulatory period.

Low values ​​are seen in poor ovarian function, premature ovarian failure, and Sheehan's syndrome.

6) Testosterone (T): Its main function is to promote the development of the clitoris, labia and mons pubis. It has resistance to estrogen and has a certain impact on systemic metabolism.

*The normal concentration of T in female blood is 0.7-3.1 nmol/L.

Among the six sex hormone values ​​introduced above, pregnant women need to check another one, which is the progesterone value. However, when testing whether there is an endocrine disorder, the measurement is usually performed on non-pregnant women, so it usually will not specifically show the level of progesterone. Friends need to pay attention to this.
