FSH is a follicle-stimulating hormone, which helps to regulate and accelerate the functional development of the gonads in the human body. During the luteal phase, FSH stimulates the production of progesterone and, together with estradiol, facilitates the ovarian response to LH.1. What role does the hormone FSH play?
FSH hormone, English name is Follicle Stimulating Hormone, is a hormone released from the anterior pituitary gland in the brain.In a woman's body, FSH has the effect of stimulating oocyte development, when a woman has polycystic ovary syndrome (PCOS), she often has a very low FSH index, potentially leading to infertility. Normally, an adult woman has a high level of FSH in her blood, which indicates maturation of the ovaries. In the male body, FSH is a hormone that stimulates the development of the seminiferous tubules and promotes sperm production.

2. What is the FSH hormone test?
FSH test results allow the diagnosis of hypogonadal dysfunction, menstrual disorders, precocious puberty, menopause or infertility in women and function of the hypothalamus and gonads in women. both male and female. Specifically, the role of the FSH test in men and women is as follows:Test for male hormone FSH: In men, follicle-stimulating hormone (FSH) stimulates Sertoli cells to produce sperm. FSH hormone will be mainly secreted in the pituitary gland in rhythms of the day. The half-life of FSH is 3 to 5 hours. Therefore, the FSH index will have little change during the day. Normally, the body of a healthy man, the amount of FSH hormone will be in the range of 2 - 12 mIU/ml. If the FSH index is high, it means that the testes will not be able to respond promptly to the stimulation of the internal organs. gonadal secretion and spermatogenesis were impaired. When the testicles are no longer able to produce sperm, it means that there will not be any effective therapy. If the FSH hormone level is low, it is possible that the patient has hypothalamic, hypopituitarism.

Female hormone FSH test: In women, follicle-stimulating hormone (FSH) will be secreted from the pituitary gland and has the effect of stimulating the development of ovarian follicles. In case of suspected female hormone disorders, quantitative FSH testing is required. FSH hormone plays a very important role in female follicle stimulation, it develops through the production of estradiol and progesterol, facilitating increased secretion of estrogen during the follicular phase.
Conducting an FHS test will show the status of the follicles in the ovary and signal when the egg is about to be released. In particular, during the luteal phase, the hormone FSH can also help stimulate the production of progesterone, control the amount of FSH and regulate the reproductive process. When the FSH test is combined with several other tests, it can find the cause of irregular periods, signs of a pituitary gland disorder, or disease related to the ovaries.
How to get samples for FSH hormone test: The FSH test is done on serum and does not require the patient to fast before blood collection. In some cases, patients may be advised to stop all medications that may alter test results and FSH levels within 48 hours prior to testing.
3. What is the normal FSH index?

For women, each stage will have a different FSH index. The normal indicators in each stage are as follows:
Ovarian follicle formation stage: FSH index is 1.68 - 15 lU/L; Mid-cycle: FSH index is 21.9 - 56.6 lU/L; The luteal phase: FSH index is 0.61 - 16.3 lU/L; After menopause: FSH is 14.2 - 5.3 IU/L. For adult males, the normal FSH index will be 1.24 - 7.8 IU/L and for prepubertal males 1.0 - 4.2 IU/L.
The results of the follicle-stimulating hormone (FSH) test may be altered due to broken red blood cells in the specimen or the presence of radioisotope for scanning within 1 week before the patient's blood draw. test. Other causes may be due to the patient taking drugs that can lower FSH levels such as: oral contraceptives, estrogen, testosterone, progesterone.
4. Clinical significance of FSH . test index
The FSH test is the test of choice when evaluating non-puberty, polycystic ovary disease, and primary amenorrhea. In particular, FSH test results are useful in probing infertile patients.
For female patients, the FSH test will always be combined with a quantitative test for LH and estradiol levels. For men, the FSH test results will always be analyzed in conjunction with the semen analysis results.
