<B>Objective:</B> We examined infertility cases with endometrial polyps. <BR><B>Design:</B> Retrospective study. <BR><B>Setting:</B> Infertility clinic.<BR><B>Patients:</B> Fifty-eight infertile women undergoing transvaginal ultrasonography and hysteroscopy<BR><B>Intervention:</B> Transvaginal ultrasonography and hysteroscopy<BR><B>Main outcome measures:</B> The size and location of endometrial polyp<BR><B>Results:</B> We compared the patient group in which the results of transvaginal ultrasonography and hysteroscopy corresponded (Corresponding Group) and the patient group in which the results did not correspond (Non-Corresponding Group). The average size of endometrial polyps in the non-corresponding group (7.8 ± 2.8 mm) was significantly less than those in the corresponding group (12.4 ± 5.1 mm). In the Corresponding Group, 90% of the endometrial polyps were detected within the upper two-third of the uterine cavity (fundal side), and 10% of the endometrial polyps were detected in the lower one-third of the uterine cavity (cervical side). In the Non-Corresponding Group, 44% of the endometrial polyps were detected within the upper two-thirds of the uterine cavity (fundal side), and 56% of the endometrial polyps were detected in the lower one-third of the uterine cavity (cervical side).<BR><B>Conclusions:</B> Endometrial polyps that are not detected by transvaginal ultrasonography can be identified by hysteroscopy. Because the polyp size was small in the Non-Corresponding Group and more than 50% of the endometrial polyps are located in the lower portion (cervical side) of the uterine cavity, the endometrial polyps in the Non-Corresponding Group may not be a cause of infertility.
