Normal menstrual cycles are regarded as a biologic indicator of overall adolescent health (1), yet adolescent girls and their caregivers are often unsure about normal ranges for menstrual cycle length, duration, and amount of flow during adolescence (2). Several factors contribute to the lack of menstrual health literacy. Menstruation is still a taboo subject in some cultures, which means it may not be discussed at all (3). Some young women may have never been informed of menstruation and the physical changes that occur during puberty. Even in high-income countries, both young women and their parents frequently report feeling uncomfortable talking about menstruation, resulting in poor menstrual health literacy (4). Additionally, there could be confusion among caregivers regarding the differences between the menstrual cycles of adolescents and adults. Moreover, studies show that physicians also lack knowledge in this area, with only a small number of pediatricians providing counseling on this topic (5). The lack of accessible and youth-friendly sexual and reproductive health services worldwide makes this challenge worse (6).

The internet, especially YouTube, has become an important source of health-related information in recent years (7). Using the Internet as a source of information has become more prevalent, particularly for topics deemed taboo or when young people feel uncomfortable discussing such matters with health care providers. Some studies found that mass media and the Internet were either the only source of information available to females concerning menstruation or served as a supplement to other sources (8). While YouTube content is easily accessible, there are increasing concerns about the quality and accuracy of online medical information (9).

Little research has been conducted on the content and quality of YouTube videos for menstrual problems. In a study evaluating the reliability and quality of YouTube videos on ovarian cysts, it was found that the number of videos posted about this condition was limited, and the videos were generally of poor quality (10).

Abnormal uterine bleeding (AUB) is defined as an abnormal quantity, frequency, duration, and/or pattern of uterine bleeding (4,11). Although common in adolescents, it can lead to severe anemia, a decline in quality of life, and an increase in depression and anxiety, particularly when treatment is delayed (12,13).

Due to the reasons discussed above, we believe YouTube videos may serve as a resource for youth experiencing AUB. Consequently, the purpose of this study was to examine the quality and dependability of YouTube videos concerning AUB in adolescents and, to the best of our knowledge, provide the first data on this topic.
