How Reliable is YouTube Regarding Testicular Cancer? What Has Changed Over Time?

Aim: Our study aimed to evaluate the reliability and quality of YouTube videos related to testicular cancer and assess changes in their quality over time.Method: In July 2024, this study retrospectively analyzed publicly accessible YouTube videos. The first 172 videos retrieved using the keyword “testicular cancer” were evaluated. The videos were analyzed and scored using the modified DISCERN, Journal of the American Medical Association (JAMA), and Global Quality Scale (GQS) scoring systems. After applying the exclusion criteria, 151 videos were included in the final analysis.Results: The most common sources of the videos were health information websites and individual physicians/urologists. In our study, the mean JAMA, modified DISCERN, and mean GQS scores were 1.01 ± 0.92, 1.73 ± 1.32, and 1.79 ± 0.92, respectively. The average duration of videos uploaded after the onset of the coronavirus disease 2019 pandemic was significantly longer, whereas the average number of views was higher for videos uploaded during or before the pandemic. However, no statistically significant differences were found between the two periods in terms of JAMA, GQS, and modified DISCERN scores. Additionally, a positive correlation was observed between video duration and the modified DISCERN, JAMA, and GQS scores.Conclusion: Our study demonstrated that the quality of YouTube videos related to testicular cancer has not improved over time, and the production of low-quality content continues. Additionally, no significant change in video quality was observed after the pandemic.
