Introduction: An increasing number of patients are seeking premature ejaculation (PE) therapy online. Although health care information on the Internet about PE is abundant, the quality of information about its treatment on YouTube, the most visited online video streaming service, is unknown.Aim: The aim of this study was to assess the role of videos pertaining to the treatment of PE through YouTube.Methods: A cross-sectional study was performed through YouTube using the keywords “cure premature ejaculation,” “end premature ejaculation,” “stop premature ejaculation,” or “premature ejaculation treatment.” The videos were sorted as reliable or nonreliable by 2 urologists as they may contain scientifically proven information or not. Nonrelevant, non-English, and silent videos were excluded. Video demographics were analyzed by the quality and source of the video.Main Outcome Measures: A 5-point global quality scale, a 5-point modified reliability (DISCERN) tool, kappa statistic, the intraclass correlation coefficient, and descriptive statistics in the form of proportions and percentages were used.Results: Of the 800 videos, 668 were excluded because they were duplicates (n = 389), irrelevant (n = 49), not in English (n = 284), or had no audio (n = 51). Of the 132 videos, 93 (70%) were described as reliable and 39 (30%) as nonreliable. The kappa statistic for interobserver agreement was 0.832. In the reliable information group, the reliability (2.55 ± 1.03) and quality scores of the contents (2.74 ± 1.06) were statistically higher than those in the nonreliable information group (0.23 ± 0.53 and 1.15 ± 0.48, respectively; P < .05). The majority of the nonreliable information group comprised medical advertisement/for-profit companies (51%) and individuals (41%). There was no significant difference between the reliable and nonreliable information groups in terms of average views (P = .873) and viewed videos per day (P = .538).Clinical Implications: Evaluating videos about the management of PE holds promise for understanding what men are exposed to.Strength & Limitations: The study simultaneously investigated the quality and accuracy of YouTube videos by several aspects using validated instruments. As for limitations, there is no consensus in the literature regarding how to assess health care-related online videos, and the results were not derived from patients’ perceptions.Conclusion: The study highlights data about the treatment of PE on YouTube. Videos with reliable information outnumbered those with nonreliable information. This is the first study to demonstrate that YouTube is an important source of data on PE management. Physicians and health care providers should contribute reliable content, and YouTube should remove deceptive videos before patients watch them

BACKGROUND: Although the prognosis of childhood cancer survivors has increased dramatically during recent years, chemotherapy and radiation treatments for cancer and other conditions may lead to permanent infertility in prepubertal boys. Recent developments have shown that spermatogonial stem cell (SSC) transplantation may be a hope for restoring fertility in adult survivors of childhood cancers. For this reason, several centres around the world are collecting and cryopreserving testicular tissue or cells anticipating that, in the near future, some patients will return for SSC transplantation. This review summarizes the current knowledge and utility of SSC transplantation techniques.OBJECTIVE AND RATIONALE: The aim of this narrative review is to provide an overview of the currently used experimental injection techniques for SSC transplantation in animal and human testes. This is crucial in understanding and determining the role of the different techniques necessary for successful transplantation.SEARCH METHODS: A comprehensive review of peer-reviewed publications on this topic was performed using the PubMed and Google Scholar databases. The search was limited to English language work and studies between 1994 (from the first study on SSC transplantation) and April 2019. Key search terms included mouse, rat, boar, ram, dog, sheep, goat, cattle, monkey, human, cadaver, testes, SSC transplantation, injection and technique.OUTCOMES: This review provides an extensive clinical overview of the current research in the field of human SSC transplantation. Rete testis injection with ultrasonography guidance currently seems the most promising injection technique thus far; however, the ability to draw clear conclusions is limited due to long ischemia time of cadaver testis, the relatively decreased volume of the testis, the diminishing size of seminiferous tubules, a lack of intratesticular pressure and leakage into the interstitium during the injection on human cadaver testis. Current evidence does not support improved outcomes from multiple infusions through the rete testes. Overall, further optimization is required to increase the efficiency and safety of the infusion method.WIDER IMPLICATIONS: Identifying a favourable injection method for SSC transplantation will provide insight into the mechanisms of successful assisted human reproduction. Future research could focus on reducing leakage and establishing the optimal infusion cell concentrations and pressure.
