Comprehensive Analysis of Global Research on Human Varicocele: A Scientometric Approach

Preamble:
Revealing the mystery of varicocele:
Varicocele has long been associated with male infertility. While significant progress has been made in understanding the role of varicocele in male infertility, there are still several gaps in our knowledge. Some of these gaps include: 1) the exact prevalence of varicocele and its impact; 2) predictive factors for infertility in men with varicocele; and 3) mechanisms of infertility. Future research addressing these gaps may help unravel mysteries that surround the relationship of varicocele and male infertility.

What is scientometrics analysis?
Scientometric analysis of published literature is a quantitative approach that involves the study of scientific publications to analyze various aspects of scientific research on a selected topic. It involves the use of bibliometric and citation analysis methods to examine patterns, trends, and relationships within a particular field or across multiple disciplines. This analysis focuses on measuring and evaluating various indicators, such as publication output, citations, collaboration patterns, author productivity, journal impact factors, and research impact. It offers insights into the growth and development of scientific knowledge, the influence and visibility of researchers and institutions, and the dissemination and impact of research findings. Scientometric analysis plays a vital role in assessing the scholarly impact of research, identifying emerging trends, and informing decision-making processes in academia, research institutions, funding agencies, and policy development.

Capsule:
The authors of this article analyzed the publication trends in varicocele research of over 33 years (between 1988 and 2020), exposing an increasing focus on various aspects. The initial studies focused on adolescent varicocele and laparoscopic repair, but later shifted towards impact of varicocele on male fertility potential, efficacy of microsurgical repair of varicoceles, and varicocele's association with factors like body mass index and seminal oxidative stress (OS). Few studies have explored the prevalence and risk factors of varicocele, and the impact of varicocele treatment on seminal OS and sperm DNA fragmentation. Additionally, there is a lack of research on reproductive outcomes with different assisted reproductive technologies and the paternity endpoint.

Recommendation:
To enhance varicocele research, collaboration between clinical and research institutions around the world is crucial, along with large-scale studies and long-term follow-ups. This collaborative approach could address important questions about the specific males affected by varicocele, the mechanisms underlying varicocele-induced damage, and improve clinical management practices globally.
