Worldwide research trend of publications concerning spermatogenesis over past 10 years: A bibliometric study

Abstract

Fertility is a hot topic and many publications on spermatogenesis has been published during the past 10 years (2012–2021). This study aims to analyse the research trends and dynamics on spermatogenesis using bibliometric methods. In this study, only articles with an annual average citation of 1 or more were selected for analysis, and a total of 4849 articles were analysed. The results show that in the field of spermatogenesis over the past 10 years, mainland China and the United States are the two leading countries, and international collaboration becoming increasingly close; Nanjing Medical University is the most widely published and collaborated institution; PLOS One and Biology of Reproduction are the most published and cited journals; Andrologia is the most popular journal in Andrology subspecialty; Zhang has made the largest contribution, with the highest number of publications and total citations; ‘testis’, ‘male infertility’ and ‘apoptosis’ were the most researched trend topics. The future trends on spermatogenesis are likely to favour hot topics such as ‘inflammation’, ‘transcriptomics’ and ‘exosomes’. In the conclusion, our study analyses the research trends on spermatogenesis over the past 10 years, which will provide a reference for researchers in this field.

Identification and validation of diagnostic signature genes in non-obstructive azoospermia by machine learning

“…Since Nelson [25] first questioned the changes in male sperm quality, more and more studies have shown that the sperm quality of adult men tends to decline over time [26][27][28][29]. In recent years, with the improvement of people's living standards, the problem of male fertility has aroused widespread concern, of which the most complex is azoospermia [30].…”
