Poor ovarian function will affect the normal development and discharge of follicles in the ovaries. Irregular or non-ovulation will lead to low levels of progesterone in the body, and the endometrium will not be able to peel off completely without producing a secretory phase response, which will lead to irregular vaginal bleeding, prolonged menstrual periods and other discomforts. At the same time, it should also be noted that if the endometrium lacks progesterone antagonism, it will lead to its continuous proliferation under the action of estrogen, which will increase the occurrence of endometrial polyps and endometrial cancer. Therefore, for women with menopause, decreased menstrual flow, prolonged menstrual period or irregular vaginal bleeding, it is recommended that they go to the gynecology department of a regular hospital to improve ultrasound, sex hormones and other related examinations, and then take active treatment under the guidance of the doctor after clarifying the cause of the disease.
