Objective: The number of studies in the field of andrology is increasing day by day, but a bibliometric study covering the entire literature on andrology has not yet been conducted. This bibliometric study aims to shed light on the question of where we came from and where we are going in andrology from past to present. It also aimed to summarize the intellectual structure of andrology to reveal global productivity and identify and map the latest trends of scientific articles published in the field of andrology.
Materials and methods: 16,659 articles published between 1980 and 2022 were extracted from the Web of Science and analyzed using various statistical methods. Bibliometric network visualization maps revealed trending topics, global productivity, the most influential studies, and international collaborations. Spearman's correlation analysis was used for determining correlations.
Results: The top three productive countries were United States of America (3,452; 20.7%), China (2,300; 13.8%), and Germany (1,069; 6.4%). The top two most productive authors were Agarwal A. (n=130) and Nieschlag E. (n=130). The most productive institution was the Egyptian Knowledge Bank (n=422). From past to present, the most studied subjects were testis, male infertility, spermatozoa, testosterone, infertility, erectile dysfunction, spermatogenesis, sperm, prostate cancer (PCA)/neoplasms, oxidative stress, fertility/fertilization, semen, rat(s), apoptosis, azoospermia, sperm motility, human and varicocele.
Conclusions: The trend topics that have been researched more in recent years include erectile dysfunction, oxidative stress, prostate cancer, sperm quality, sperm parameters, infertility, premature ejaculation, diabetes mellitus, obesity, prognosis, sperm DNA fragmentation/damage, antioxidant, asthenozoospermia, varicocelectomy, COVID-19, inflammation, prostatectomy, metabolic syndrome, hypogonadism, benign prostatic hyperplasia, lower urinary tract symptoms, meta-analysis, sexual dysfunction, peyronie's disease, and proliferation. We identified the research leadership of China, Japan, Turkey and India, in addition to Western countries, such as the USA and European countries.
