Impotence literature: Scientometric analysis of erectile dysfunction articles between 1975 and 2018.

Erectile dysfunction (ED) is portrayed as lasting deficiency to achieve or sustain penile erection in successful vaginal penetration and is a major problem affecting the quality of life in men. The number of ED sufferers worldwide is anticipated to reach 322 million, by 2025. In recent years, many publications and studies have been made in the field of ED. Our aim was to perform a detailed bibliometric analysis of erectile dysfunction literature. In this study, we downloaded the data of the publications from the Web of Science Core Collection. All items indexed in these databases between 1975 and 2018 were included. Documents produced in 2019 were excluded. We searched in WoS databases for the keywords of 'erectile dysfunction' and 'impotence'. Our basic search into WoS databases retrieved a total of 28,266 documents indexed between 1975 and 2018. English dominated impotence literature (92.541%) followed by German, French and Korean (2.136%, 1.920% and 1.180% respectively). The United States has made tremendous improvement in ED studies and is still the effective country. The most prolific author was Montorsi F with 330 articles from Italy, and three-fifth of the authors were from the USA.
