<Abstract>BACKGROUND: One of the biggest problem today that most developing countries are faced with is the uncontrolled population growth; a serious threat to the international community. One of the most accessible contraceptive methods is the hormonal methods in which low-dose estrogen (LD) combined pills are considered as the most common among them. The most important reason for discontinuation of the combination pills is the side effects and following the discontinuation, it can lead to unwanted pregnancy. Promotion of more new methods and providing better methods with lesser side effects can be an important step towards solving some of the problems and increasing the usage percentages of contraceptive methods. This study therefore aimed to compare the effects of Yasmin and LD on menstrual cycle changes.METHODS: In this clinical trial study, 60 women referred to the Family Planning Health Center of Isfahan in 2008 were studied that finally after the sample loss, 27 and 24 samples were placed in Yasmin and LD groups, respectively. A questionnaire was used in order to collect the data. Content validity test and re-test also were used to confirm the validity and reliability of the questionnaire. To analyze the data, SPSS software and descriptive and inferential statistical methods were used.RESULTS: The results of this study indicated that the bleeding rate in the Yasmin group within the next six month compared to taking them before was significantly lower than that in LD group (p = 0.02); but there was no significant difference in terms of menstrual bleeding duration and the two menstruation interval between the two groups (p = 0.2). There was no significant difference between the Yasmin and LD groups in terms of delay in menstruation and dysmenorrheal. Spotting rate significantly was higher in Yasmin group than that in LD group (p = 0.02). There was a significant reduction in terms of bleeding rate changes and menstrual bleeding duration in both Yasmin and LD group at the following next six months in comparison with before the consumption (p &lt; 0.05).CONCLUSIONS: According to the obtained results, the consumers of oral combination of Yasmin pills have experience fewer menstrual disorders than LD consumers. Therefore, it is recommended to start using Yasmin pill in the family planning units in Iran.KEY WORDS: LD, menstrual cycle changes, pill, Yasmin.</Abstract>
