Abstract: Endometrial polyps (EP) is a benign local lesion of the endometrium. It is common in women of childbearing age. Observational studies have shown that EP has an adverse effect on fertility, but its pathogenesis is not clear. Diagnosis methods of EP usually include two-dimensional transvaginal ultrasound and three-dimensional transvaginal ultrasound, saline infusion sonohysterography (SIS) and hysterosalpingography (HSG) and hysteroscopy. Hysteroscopy and biopsy is the gold standard for the diagnosis of EP. In most cases, small and asymptomatic polyps can adopt expectant therapy, however, in order to improve the natural conception or pregnancy rate of assisted reproduction, surgical resection of endometrial polyps is still the first choice for the treatment of infertility patients, and the curative effect is remarkable. Relevant evidence suggests that endometrial polypectomy in the course of ovarian stimulation improves the success rate of in vitro fertilization.
