Follicle-stimulating hormone is a glycoprotein hormone secreted by the pituitary gland. Its main role is to promote follicle cell proliferation and differentiation, follicular development and maturation and normal ovarian growth, as well as to promote the synthesis and secretion of estrogen by the granulosa cells of the ovary. Follicle stimulating hormone is secreted under the control of the hypothalamic-pituitary-ovarian axis, and if it is elevated, it indicates poor ovarian function. The standard value of follicle stimulating hormone (blood): FSH in normal females is 5 to 40mIU/ml, usually less than 5mIU/ml before puberty and more than 40mIU/ml after menopause. the concentration of blood follicle stimulating hormone also varies with the menstrual cycle, ranging from 1.5 to 10mIU/ml in the preovulatory period, 8 to 20mIU/ml in the ovulatory period, and If the follicle stimulating hormone is found to be high during the test, it may mean that estrogen secretion is insufficient, reflecting to some extent the reduced reserve function of the ovaries. Low ovarian function naturally and directly affects a woman’s ability to conceive. This should be considered in the context of age and systemic factors. If you are older than 40 years old and your FSH is above 40, you should consider that you are approaching menopause, and if you are younger than 40 years old, you should consider premature ovarian failure. Other diseases such as ovarian dysplasia and impaired ovarian function can cause high follicle stimulating hormone. Pituitary disorders can also cause high follicle stimulating hormone, such as amenorrhea and lactation syndrome, pituitary tumors, pituitary dysfunction, etc. can also cause excessive secretion of follicle stimulating hormone by the pituitary gland. High follicle stimulating hormone can cause ovarian ovulation disorder, irregular menstruation, amenorrhea, infertility and a series of other problems. It seriously affects women’s health. Most of the treatment is based on medication, and more common is the artificial cycle. Usually 3-6 cycles in a row can restore menstruation to normal. Through systematic treatment, the female endocrine level can be maintained. Pay attention to a scientific diet, a regular work and rest schedule, and a combination of work and rest. In conclusion, high follicle stimulating hormone should be considered in conjunction with age and systemic factors, and treatment and intervention should be tailored to age and needs.
