      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Random allocation rule: First, 30 letters A and 30 letters B are written on special papers that are not marked inside. Then all of them are placed in a bag and for each patient, after obtaining informed consent, a paper is removed randomly and without replacement, and based on the letter written on it, the desired intervention is performed for the patient. In addition, interventions A (Dienogest) or B (Placebo) are determined by a lot, Blinding description: This study is double-blind. In this study, the participants and the physician who evaluates the outcomes, are blind. The participants are blinded by using a placebo that is the same as Dienogest, and the physician evaluating the outcomes does not know the treatment group of the participants.</study_design>

      <i_freetext>Intervention 1: Intervention group: For this group of patients, 0.5 milligrams Dienogest (one-quarter of a tablet produced by the Aburihan pharmaceutical factory named Dinovol) is prescribed twice a day (every 12 hours) from the second day of the patient's mensuration cycles and continues for 12 weeks. Dienogest is the newest generation of progesterone and the only oral progesterone. During the study period, every 4 weeks, the patient is visited regarding dysmenorrhea and drug side effects. Intervention 2: Control group: For this group of patients, one-quarter of a placebo tablet, produced by the Aburihan pharmaceutical factory, is prescribed twice a day (every 12 hours) from the second day of the patient's mensuration cycles and continues for 12 weeks. The placebo tablet is the same as Dinovol. During the study period, every 4 weeks, the patient is visited regarding dysmenorrhea and drug side effects.</i_freetext>
