Amenorrhea is caused by problems with the uterus, such as congenital absence of a uterus, uterine dysplasia, or diseases during childhood involving the endometrium, resulting in adhesions or scars. Although the ovarian function is good, female Character development is normal, but menstruation is absent. When diseases occur after menarche, such as endometrial tuberculosis, endometrial schistosomiasis, endometrial suppuration, or when the basal layer of the endometrium is scraped off during dilation and curettage, secondary amenorrhea occurs due to the inability to respond to ovarian hormones.

　　⑵Ovarian causes. Also called ovarian amenorrhea. Normal menstruation occurs because the hormones secreted by the ovaries act on the endometrium, causing it to change, then fall off and bleed. If the ovaries cannot secrete hormones, the endometrium will not change and menstruation will stop naturally, such as congenital ovarian dysplasia, premature ovarian failure wait. Amenorrhea due to this cause is often accompanied by degeneration of female characteristics, such as breast becoming equal.

　　⑶Pituitary causes. Called pituitary amenorrhea. The pituitary gland is located below the brain and is very small, but it controls the endocrine organs of the body. When the pituitary gland function changes, the ovarian function decreases. Common pituitary lesions are tumors and hypopituitarism. 》》》》 5Women are most likely to attract peach blossoms
