The membranous adhesions could induce implantation failure despite transplantation of high quality of embryo. Clinically, of the patients who have membranous filmy adhesions, endometrial polyps have been found in not infrequently. Thus this study was tried to evaluate the features of endometrial polyps and the effect of endometrial polyps on formation and extents of membranous adhesions in uterine cavity of infertile patients under hysteroscopy. A retrospective study was conducted on 34 infertile patients who were diagnosed as endometrial polyps with membranous adhesions during hysteroscopy from July 2008 to July 2011. Number, size, location and morophologic type of endometrial polyps were investigated. If needed, methylene blue solution was instillated to endometrial cavity to identify membranous adhesions. Then, associations between membranous adhesions with features of endometrial polyps were evaluated. Mean size of endometrial polyp was $1.6{\pm}0.6$ cm, the bigger of endometrial polyps was, the larger of extents of membranous adhesions. (p<0.05). Endometrial polyps were locate evenly in endometrial cavity as follows: anterior uterine wall, 39.1%; posterior uterine wall, 34.8%; lateral uterine wall, 26.1%; upper: 29.4%, middle: 32.4%, lower segment, 35.3%. Mean number of endometrial polyps was $2.26{\pm}1.3$. The pedunculated type was 37.7% and sessile type was 32.4%. There was no statistically significant association of location, number and morphologic type of endometrial polyps with membranous adhesions. In conclusion, hysteroscopy before in vitro fertilization on infertile patients was worthy because of removing of endometrial polyps and membranous adhesions.
