What is serum follicle stimulating hormone?

FSH (follicle-stimulating hormone) is a glycoprotein growth hormone metabolized by the pituitary gonadotropin estrogen somatic cells, which changes regularly with the physiological cycle. Its physiological function is mainly to promote the perfection of eggs and the metabolism of female hormones. Can diagnose premature ovarian failure: If FSH exceeds 40U/L, premature ovarian failure is considered. If the period occurs at least twice within a month, it can be considered as ovarian insufficiency. It can also help diagnose polycystic ovary syndrome: if LH/FSH is greater than 2-3, the possibility of polycystic ovary is considered.

The blood cell follicle-stimulating hormone that this netizen often talks about refers to follicle-stimulating hormone in medicine, abbreviated as FSH. FSH is a commonly used hormone test, which is secreted by the pituitary gland in the human brain. Its function, to put it simply, is to promote the growth and development of eggs.

In different physiological cycles and at different stages, the standard value of FSH is different. The basic FSH level is generally used, that is, the FSH level is measured on the third to fifth day of menstruation. At this time, the FSH level is called the basic level. If the basic level rises to more than 25, it is called POI, which is primary ovarian insufficiency.

If the FSH level is already over 40 and the age is under 40, this is called POF, which means ovarian failure. Therefore, testing basic FSH values ​​can help to determine the function of the ovaries. In addition, the FSH value before ovulation can also be measured. There will be a peak period of FSH before ovulation. The peak period at this time is a major manifestation of the complete development of the uterus and the upcoming ovulation period. Therefore, at different stages of the menstrual cycle, the blood cell FSH value, that is, the value of follicle-stimulating hormone, is different. Generally, what is checked is the level of basic follicle-stimulating hormone.
