Abstract: Endometrial polyp is a common gynecological disease, which is a cause of abnormal uterine bleeding and infertility. Endometrial polyps may be related to enviromental estrogen exposure or chronic inflammatory response. Morbidity of endometrial polyps increased in infertility women. Three-dimensional ultrasound, SIS, hysterosalpingograms (HSG) and hysteroscopy are main diagnostic methods. SIS and hysteroscopy are two effective and reliable methods with higher sensitivity and specificity. Endometrial polyps less than 10 mm in diameter may undergo spontaneous regression. Blind dilation and curettage (D&C) is not recommended. Hysteroscopic polypectomy, as main treatment of conservative surgery with low complications, can improve reproductive outcome of infertility women. It is necessary to have more high-quality randomized controlled trials (RCT) to answer whether the hysteroscopic removal can be used as a conventional therapy in those infertile women with endometrial polyps.
