A bibliometric analysis of international publication trends in premature ejaculation research (2008–2018)

Abstract

The incidence of premature ejaculation (PE) has been on the rise over the years. Thus, significant research efforts have been directed toward understanding the pathogenesis and hence treatment of PE. Here, we performed a comprehensive analysis of the worldwide trends in research outputs in the field of PE. This study investigated the universal findings of previous PE studies and the trending issues surrounding the condition. We employed the Web of Science Core Collection for data collection. The Excel (2016) and CiteSpace IV were used for information analysis. The information was categorized using journal names, institutions, research frontiers, citation reports, regions/countries, and authors. A sum of 886 publications concerning PE between 2008 and 2018 were identified as of July 6, 2019. The highest number of publications was identified in the Journal of Sexual Medicine published. The United States of America (USA) had the highest number of publications and H-index value. The highest co-citations were from Waldinger MD. The most common keyword was ‘drug treatment’. A steady pattern was observed for PE publications done between the period of 2008–2018. Thus, the USA is at the forefront of research on PE research. The interesting advanced research frontiers were drug treatment, circumcision, and sertraline.
