What is follicle stimulating hormone

Follicle-stimulating hormone is a hormone secreted by certain cells in the human body. This hormone is very important for us women. There are certain precautions for monitoring follicle-stimulating hormone. For example, when we monitor this hormone, we cannot take any special medications. Follicles have a certain normal range, so what exactly is follicle-stimulating hormone?

Follicle-stimulating hormone is a hormone secreted by the alkaliphilic cells of the anterior pituitary gland. It is composed of glycoprotein and its main function is to promote the maturation of follicles. Follicle-stimulating hormone can promote the proliferation and differentiation of granulosa cells in the follicle and promote the growth of the entire ovary. Its action on the seminiferous tubules of the testicles can promote sperm formation.

Follicle-stimulating hormone is secreted in the human body in a pulsatile manner, and in women it changes with the menstrual cycle. The determination of serum follicle-stimulating hormone is of great significance for understanding the endocrine function of the pituitary, indirectly understanding the functional status of the hypothalamus and ovaries, predicting ovulation time, and diagnosing and treating infertility and endocrine diseases.

Decreased follicle-stimulating hormone is seen in estrogen and progesterone treatment, secondary sexual dysfunction, hypopituitarism, Sheehan syndrome, polycystic ovary syndrome, and advanced adenohypophysitis.

Elevated follicle-stimulating hormone is seen in testicular seminoma, Klinefelter's syndrome, Turner syndrome, primary amenorrhea, congenital ovarian dysgenesis, after treatment with adrenocortical hormones, primary reproductive insufficiency, ovarian obesity, early hyperpituitarism, giant cell degenerative lung cancer, etc.

Taking birth control pills, estrogen, or during pregnancy may affect the determination of serum follicle-stimulating hormone, so care should be taken during testing. And because the physiological changes of follicle-stimulating hormone in serum are large, when judging and interpreting a certain pathological phenomenon, the measurement should be repeated many times to avoid misjudgment.

It is normal for women of normal reproductive period to ovulate normally every month. If the follicle stimulating hormone 15 is checked during menstruation, it is recommended to analyze whether there is a decrease in ovarian reserve function in combination with the ovarian condition.

The size of a mature follicle is 18-25MM. The factors that cause ovulation disorders include: central nervous system anovulation; hypothalamic anovulation; pituitary anovulation; ovarian anovulation; polycystic ovary syndrome; luteinized unruptured follicle syndrome; others: other endocrine systems other than gonads, such as the thyroid gland
