Functional hypothalamic amenorrhea

The hypothalamus is an important reproductive organ. The hypothalamus regulates the function of the pituitary through nerve conduction and pituitary portal system to make the pituitary secrete corresponding hormones. These hormones act on the ovary to produce steroid hormones to ensure the normal maintenance of reproductive function. On the one hand, the function of hypothalamus is stimulated by central nerve cells and regulates the secretion of pituitary stimulating hormone; On the one hand, it is regulated by the negative feedback of hormones secreted by the pituitary gland. Neuroendocrine cells in the arcuate nucleus of the central eminence of the hypothalamus release GnRH in a pulsed manner. Mental tension, strenuous exercise and hypothalamic tumors can cause abnormal GnRH secretion, leading to anovulation and amenorrhea.
