Plagiarism is a common form of academic misconduct that extensively jeopardises the quality of scientific publication. The purpose of this study is to determine the extent of plagiarism in the most influential andrology articles. A total of 77 highly cited andrology articles were analysed for their similarity index using iThenticate and Turnitin. The articles were categorised based on the year (before and on/after 2000) and type of publication (review and research articles), and the similarity indices were compared. Furthermore, the analysed articles were categorised based on the level of similarity using an arbitrary similarity index range (low: ≤10, moderate: 11-20, high: 21-50 and very high: >50) and average incidence rate (%) was determined. Our analysis revealed a higher percentage of the similarity indices for reviews than research articles. We noticed a higher similarity index for articles published on/after 2000 than those published before. The majority of the influential articles in the field of andrology showed a low similarity index, while some articles exhibited moderate to high levels of similarity. These findings support the need for the development of similarity index guidelines as a major pre-requisite for establishing a more transparent and efficient system to address plagiarism in scientific publications.
剽窃是一种常见的学术不端行为，广泛危及科学出版物的质量。本研究旨在确定最有影响力的男科文献中的剽窃程度。使用 iThenticate 和 Turnitin 分析了 77 篇高引用的男科文章，以确定其相似指数。根据发表年份（2000 年之前和 2000 年之后）和出版物类型（综述和研究文章）对文章进行分类，并比较相似指数。此外，根据任意相似指数范围（低：≤10、中：11-20、高：21-50 和非常高：>50）对分析文章进行分类，并确定平均发生率（%）。我们的分析显示，综述文章的相似指数百分比高于研究文章。我们注意到，2000 年以后发表的文章的相似指数高于 2000 年之前发表的文章。该领域有影响力的大多数男科文章的相似指数较低，而一些文章的相似指数则处于中等至高的水平。这些发现支持制定相似指数指南的必要性，这是建立一个更透明和有效的系统来解决科学出版物中的剽窃问题的主要前提。
