In this study, fifty women childbearing ages between 20-40 years referred to the gynecological and midwifery section of the hospital, who had the asymptomatic endometrial polyps smaller than 1.5 cm. They were randomly divided into two groups "control" and "case" individually 25 members. The group case, were treated for three months with oral contraceptive pills. Women were examined in sonography before and after taking pills in order to measure the polyp size. Almost 24% of the group case responded to treatment, 32% size reduction and 44% remained with no change in size. While, in the control group there was 28% size reduction, 37% neutral and 35% encountered increase in size was unchanged. The average size of endometrial polyps in the group control did not take statistical significance difference before and later than treatment (9.5 vs. 8.6 mm, p = 0.297). However, the size of the polyp in the group case had significant statistical difference before and after the treatment (9.5 vs. 6.3 mm, p<0.05). Use of oral contraceptive pills in the treatment of endometrial polyps is low cost and non-invasive compared with such surgical procedures as curettage and hysteroscopy. Therefore, in this regard, further studies are recommended.]]>Arnes, M., B. Hvingel and A. Orbo,20143423192324Barati, M., S. Masihi and S. Ilkhan,201026380383Ben-Yehuda, O.M., Y.B. Kim and R.S.
