Introduction: The onset of menstruation coincides with the beginning of the puberty stage in females, as menstruation is a physiological process. According to the World Health Organization (WHO), the teenage phase occurs between the ages of 10 and 19. The use of sanitary pads, their appropriate disposal, and subsequently the appropriate washing of the vaginal area, followed by hand washing, are all components of good menstrual hygiene practices. Aims: The purpose of this study is to evaluate how well an information booklet can improve adolescents’ preexisting knowledge of and attitude toward menstruation in both male and female students. Methods: A descriptive research strategy was utilised for this study as the methodology for the investigation. The research was carried out at the KCT SCHOOL in Karad. Through the utilization of the Convenient Sampling Method The study included a sample size of one hundred. A questionnaire with a defined format served as the primary research instrument. Both descriptive and inferential statistics were used in the process of data analysis. Result: The findings of the current research indicate that out of a total of 100 adolescents (50 boys and 50 girls), 29 of them had average knowledge and 68 of them had inadequate knowledge before the exam. Following the presentation of the module on menstruation, the vast majority of them achieved a score of 92 or higher on the post-test. The knowledge level of the adolescent males and girls was significantly different before and after the exam, and this difference was statistically significant. The current research demonstrates that there is a statistically significant association between the source of information and the amount of knowledge demonstrated on the pre-testing phase. Conclusion: The findings of the study indicate that participants’ understanding of menstruation is inadequate, as the conclusion of the study states. They need a comprehensive orientation procedure that will help them expand their knowledge while also assisting them in making informed decisions.
