Purpose: YouTube{}^{\text{TM}} is one of the most popular social media platforms on the internet, and patients with chronic disease frequently use it to seek treatment options. In this study, we aimed to evaluate the quality of YouTube videos about erectile dysfunction. Materials & methods: The terms “erectile dysfunction treatment”, “erectile dysfunction surgery”, and “cure erectile dysfunction” were entered into the YouTube search bar. A total of 56 videos were included in the study. Videos’ view counts; upload dates; like, dislike, and comment counts; uploader qualifications; length; and content were recorded. Video power index (VPI), Quality Criteria for Consumer Health Information (DISCERN), and Journal of the American Medical Association (JAMA) scores were determined. Results: Thirty-two (57.1%) videos consisted of real images, and 24 (42.9%) contained animated images. Twenty-four (42.9%) videos were uploaded by physicians, and 32 (57.1%) were uploaded by non-physicians. The mean like count of the videos was 5,307 \pm 17.618, the mean dislike count was 560.07 \pm 1548.07, and the mean comment count was 235 \pm 373. The mean VPI value of the videos was calculated as 81.19 \pm 21.19, the DISCERN score was 30.5 \pm 8.1, and the JAMA score was 1.23 \pm 0.55. Overall quality was very poor in 24 (42.9%) of the examined videos, poor in 21 (37.5%), average in 10 (17.9%), and good in one (1.8%). Conclusion: The overall quality of YouTube content on erectile dysfunction was not sufficient to provide reliable information for patients. Physicians should warn patients about the limitations of YouTube and direct them toward more appropriate sources of information.
