Therefore, it is essential that the textual content of these videos is clear, trustworthy, and of high quality.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Aim: &lt;/strong&gt;Are the AI-assisted acquired texts' qualities and comprehensibilities of YouTube videos about PE enough and suitable for the patients?&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;On October 25, 2024, Google Trends analysis identified the 25 most searched phrases for \"Penile enlargement.\" Non-related terms were excluded, and the relevant keywords were searched on YouTube. Only content about PE included; excluding duplicates, non-English videos, YouTube shorts, those under 30 seconds, silent, and music-only videos. Videos were transcribed using Whisper AI, and their quality was assessed by M.F.Ş, E.C.T., and Ç.D. using the GQS (global quality scale) and DISCERN, the readability was evaluated via Flesch-Kincaid (FKGL and FKRE) measures. High assessor agreement was noted (Pearson r = 0.912). Videos were categorized by uploader, and metrics such as views, likes, comments, and duration were recorded. The Chi-square test was used for categorical variable comparisons; the Kruskal-Wallis H-Test was applied when normality and homoscedasticity were not met, with Bonferroni post hoc correction for multiple comparisons.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Outcomes: &lt;/strong&gt;The mean DISCERN and GQS scores were 51.23 ± 13.1 and 3.32 ± 0.9, respectively. FKRE and FKGL scores were 73.12 ± 11.7 and 5.85 ± 2.1. Physicians (n = 67) produced the most videos, while academic institutions (n = 2) produced the least. No significant differences in text quality were found between groups (&lt;i&gt;P&lt;/i&gt; = 0.067 and &lt;i&gt;P&lt;/i&gt; = 0.051).

Eligible participants completed an anonymous 47-question survey addressing sociodemographic data, APN practices, and sexual health. Facilitators played a critical role in distributing and collecting the questionnaires, which were available in five languages to accommodate the prison's population ethnogeographic diversity. Data analysis was conducted using logistic regression to identify risk factors associated with complications.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Outcomes: &lt;/strong&gt;Outcomes included the prevalence of APN use among detainees, the proportion of individuals experiencing complications, the association between APN characteristics (number and placement) and partner-related complications, as well as the rates of condom breakage and self-reported STI history.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Among 779 eligible detainees, 132 participated (17%). The majority were under 35 years old (67%), and 69% reported having APNs, with a median of 5.2 nodules per user (range: 1-22). The main motivation for APN use was enhancing partner satisfaction (60%), while 5% cited intent to harm. Complications were reported by 25%, including pain (52%), bleeding (41%), and infections (35%). Partner-related complications (pain or bleeding) were significantly associated with having five or more APNs and placement in the foreskin of the penis.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Clinical implications: &lt;/strong&gt;Given the high prevalence of APNs in the prison setting and their associated health risks, targeted health education and harm reduction strategies are essential to mitigate complications and promote informed decision-making among detainees.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Strengths and limitations: &lt;/strong&gt;The main limitation of this study was its reliance on self-reported questionnaires completed in cells, which may have affected confidentiality, response accuracy, and participation due to prison dynamics and literacy barriers. However, the approach provided valuable insight into a stigmatized topic, and collaboration with facilitators and staff helped achieve meaningful participation.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;APNs are deeply rooted in prison culture in French Guiana but pose significant health risks.
