Abstract: Endometrial polyps is one of the most common gynecological diseases，which can induce menstrual period extended，postmenopausal bleeding，infertility and other clinical symptoms. After treatment，endometrial polyps also are easy to relapse，have certain malignant transformation rate，whose etiology and pathogenesis is not clear. In recent research，this disease is correlated with genetic factors，local imbalanced steroid hormone receptor，proliferation and apoptosis，chronic inflammatory stimulation，certain drugs and cell factor. Age，postmenopausal，anomalistic uterine bleeding，use of tamoxifen，obesity，hypertension，diabetes mellitus may involved in its progression. Through translational ultrasonography，sonohysterography，hysteroscopy，uterine iodine oil imaging play an important role in its treatment process. Now from the epidemiology，pathogenesis，clinical symptoms，diagnosis and treatment，recurrence，malignant related factors，prevention of endometrial polyps，we do a review，for we can more inclusively and more correctly promulgate the mechanism and characteristics of endometrial polyps，and then we can better guide further clinical research and therapy.
