Trends in psychogenic erectile dysfunction research: a bibliometric and visualized study

Psychogenic erectile dysfunction (pED) is more common in the population of young and middle-aged males. Research relating to pED has increased significantly over the past 20 years. However, few studies have performed comprehensive statistical analysis on these publications. In this study, we highlight the current research hotspots and emerging trends relating to pED from 2000 to 2022, as determined by a focused review of the literature. Relevant articles were identified by searching the PubMed and Web of Science databases between 2000 and 2022. VOSviewer and Origin software were then used to analyze and verify emerging trends. A total of 118 articles relating to pED were included in our final analysis. Our analysis showed that research on pED is dominated by clinical studies and concentrated in journals relating to male and sexual medicine. Chinese researchers have produced the highest number of publications. In addition, over the past 20 years, pED research has focused more on pathogenesis, diagnosis and treatment. In this study, we reviewed articles related to pED that were published over the last 20 years; our findings may provide reference guidelines for researchers when designing future research on pED.
