Methods From July 2016 to July 2018, in Shijiazhuang First Hospital, 340 infertility patients were selected, among them 140 failed to assist in pregnancy (group A) and 200 without assist pregnancy (group B). In group A, there were 69 cases with endometrial polyp, 71 cases without endometrial polyp; in group B, there were 98 cases with endometrial polyp, 102 cases without endometrial polyp. The incidence of endometrial polyp in different ages, different maternal history, and infertility years were observed, the clinical pregnancy rate of patients in two groups were further analyzed. Results There were significant differences in the incidence of endometrial polyp of patients in different ages, different maternal history and infertility (P < 0.05); in group A, the pregnancy success rate of endometrial polyp excision was significantly higher than that without endometrial polyp, the difference was statistically significant (P < 0.05); in group B, the pregnancy success rate of endometrial polypectomy was slightly higher than without endometrial polyp, but the difference was not statistically significant (P > 0.05). Conclusion Endometrial polyp is important factor leading to infertility in patients, it may affect the pregnancy and reduce the pregnancy rate. therefore, for patients with infertility, hysteroscopy should be performed in the early stage, once endometrial polyp is found, they should be timely removal to improve the patients′ clinical pregnancy success rate.
