What is the normal value of follicle-stimulating hormone?

Women should actively cooperate when undergoing physical examinations. Many women do not do this. Failure to cooperate with physical examinations will have a great impact on their own bodies and will induce a variety of physical problems. So what is the normal value of follicle-stimulating hormone? Many people are not clear about this. The following is a detailed introduction so that you can have some understanding.

Normal values ​​of follicle-stimulating hormone:

Normal follicle-stimulating hormone (FSH) is 1.5-10 miu/ml in the follicular phase, 8-10 miu/ml in the ovulatory phase, and 2-20 miu/ml in the luteal phase. Normal values ​​are 5-40. Luteinizing hormone (LH) is 2-15 miu/ml in the follicular phase, 30-100 in the ovulatory phase, 4-10 in the late ovulatory phase, and 5-25 in the non-ovulatory phase. Prolactin (PRL) is 0.08-0.92 mmol/L. Estradiol (E2) before ovulation 48-521mmol/L, during ovulation 70-1835, after ovulation 272-793.

examine

All women have experienced endocrine disorders. Blood tests can be done to check whether female sex hormone secretion is at a relatively normal level to determine whether there is an endocrine disorder.

Sex hormone levels are affected by the hypothalamus, pituitary gland and ovaries. The hypothalamus is the "supreme headquarters" that releases a certain amount of hormones to issue instructions to the subordinates (pituitary gland). The pituitary gland also sends signals to regulate the subordinate glands. For the ovaries, this signal is the follicle-stimulating hormone and luteinizing hormone secreted by the pituitary gland, and prolactin is also produced during lactation.

Therefore, endocrine examination is actually to see whether the secretion levels of these hormones (including luteinizing hormone, follicle-stimulating hormone, prolactin, progesterone and estrogen) are normal.

Luteinizing hormone and follicle-stimulating hormone mainly promote follicle development and ovulation. If the test values ​​are too high, it may lead to amenorrhea or infertility. If prolactin is too high, it may be due to pituitary tumors and hypothyroidism. If progesterone is too low, it indicates hypofunction of the pituitary and ovaries.

effect

1 Directly stimulate the proliferation and differentiation of granulosa cells;

2. Induce the synthesis of FSH and LH receptors in granulosa cells, improve the responsiveness of granulosa cells to LH, so as to maintain the synthesis of ribosomes in preovulatory follicles and the formation of corpus luteum after ovulation;

3 FSH can bind to receptors on the surface of granulosa cells, activate cyclase and cAMP-dependent protein kinase to induce the expression of gene products, such as increased aromatase activity, so that more androgens are converted into estrogens;

4 FSH can also actively inhibit the synthesis of inducible factors, activins and insulin-like growth factor-1. These polypeptide substances play an important role in regulating dominant follicles and atresia.

After understanding the normal value of follicle-stimulating hormone, if a woman's own follicles have abnormalities, treatment should be carried out according to the doctor's advice. At the same time, it should be noted that in the process of alleviating her own follicle problems, she can also consult on some adverse issues so that she knows what to do best.
