Six specific standards for gynecological hormones

The six gynecological hormones are closely related to every activity of our body. This issue requires us to study and expand carefully. Each of us should pay enough attention to balance the six gynecological hormones inside and outside our body, and try not to be plagued by various external diseases. Of course, when the six gynecological hormones are unbalanced, they are not as obvious as other diseases. Therefore, we must pay more attention to the subtle changes in our body. Maybe everyone does not have a clear understanding of this. Let us learn about the six gynecological hormone methods together!

Six hormones:

1. Follicle-stimulating

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 pre-ovulation period, 8-20mIU/ml in the ovulation period, and 2-10mIU/ml in the post-ovulation period. Generally, 5 to 40 mIU/ml is considered normal. Low FSH values ​​are seen during estrogen-progestin therapy, Sheehan's syndrome, etc. High FSH levels are seen in premature ovarian failure, ovarian insensitivity syndrome, primary amenorrhea, etc. If FSH is higher than 40mIU/ml, ovulation-stimulating drugs such as clomiphene will be ineffective.

2. Luteinizing

It is also a glycoprotein hormone secreted by the alkaliphilic cells of the anterior pituitary gland. It mainly promotes ovulation. Under the synergistic action of FSH, it forms a corpus luteum and secretes progesterone. 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. A level lower than 5mIU/ml indicates gonadotropin insufficiency, which is seen in Sheehan's syndrome. If high FSH is accompanied by high LH, ovarian failure is very certain and no other tests are necessary. LH/FSH≥3 is one of the bases for diagnosing polycystic ovary syndrome.

3. Prolactin

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. During the non-lactation period, the normal value of blood PRL is 0.08-0.92nmol/L. A level higher than 1.0nmol/L is called hyperprolactinemia. Excessive prolactin can inhibit the secretion of FSH and LH, inhibit ovarian function, and inhibit ovulation.

3. Estradiol

) 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 ovarian dysfunction, premature ovarian failure, and Sheehan's syndrome.

4. Progesterone

It is secreted by the corpus luteum of the ovary. Its main function is to promote the transition of the endometrium from the proliferative phase to the secretory phase. The blood P concentration is 0-4.8 nmol/L before ovulation and 7.6-97.6 nmol/L in the late ovulation period. Low blood P values ​​in the late ovulation period are seen in luteal insufficiency, ovulatory dysfunctional uterine bleeding, etc.

5. Testosterone

50% of the testosterone in women is converted from peripheral androstenedione, about 25% is secreted by the adrenal cortex, and only 25% comes from the ovaries. The main function is to promote the development of the clitoris, labia and mons pubis. It has an antagonistic effect on estrogen and has a certain impact on systemic metabolism. The normal concentration of T in female blood is 0.7～3.1nmol/L. High blood T levels are called hypertestosteronism, which can cause infertility. When suffering from polycystic ovary syndrome, the blood T value also increases. Based on clinical manifestations, other hormones can be measured if necessary.

The above content introduces us to six methods of regulating gynecological hormones. I believe that everyone must have read these methods carefully. We do need to master some things that we cannot access in our daily life. In order to avoid similar problems in the future and not knowing how to treat them, we must learn more about various fields, which is very beneficial to ourselves.
