Abstract
Background and Objectives: The evaluative strength of available bibliometric tools in the field of clinical embryology has never been examined in the literature. The aim is to bring insight regarding the identity of clinical embryology research, introducing concerns when solely relying on the methodology of bibliometric analysis. Materials and Methods: An all-inclusive analysis of the most bibliometrically highlighted scientific contributions regarding the cornerstones of clinical embryology was performed employing the Scopus, Web of Science (WoS) and PubMed databases, between 1978–2018. An analysis of the number of publications, respective citations and h-index, g-index, along with m-quotient is presented. The top 30 contributing authors for each distinctive area of research are listed. An attempt at visualizing the yearly published articles, clusters, and collaborations of authors, along with the geographic origin of publications, is also presented. Results: Combining all searches and keywords yielded 54,522 results. In the Scopus database, employing the keyword “In Vitro Fertilization” yielded 41,292 results. The publications of the top five authors in each research field were analytically presented and compared to the total number of publications for each respective field. The research field of Preimplantation Genetic Diagnosis/Screening/Testing was allocated the highest percentage of publications produced by the top five authors. Regarding journal bibliometrics, based on the year 2017 metrics, there are only 29 journals according to WoS that refer to “Reproductive Biology”, ranking it 187th among 235 disciplines. The USA produced the highest number of publications (12,537). Conclusion: Results indicate an explosion of interest published in the literature regarding the field of clinical embryology. Further analysis on collaborations and the trends involved should be of added value as productivity between countries varies significantly. This may guide researchers, in vitro fertilization professionals, and prospective authors during literature search, while proving useful regarding manuscript design and concurring on keywords and abstract content.
Highlights
Following the advent of assisted reproduction, clinical embryology has become an evolving field of interest in science
Identified articles corresponded to publications from 1978-the year of the first publication on assisted reproduction-till 2018.Regarding journal data, the Web of Science (WoS) database was used as it presents the most accredited impact factor (IF)
The high percentage of publications produced by the top five authors (11%) was attributed to the research field of Preimplantation Genetic Diagnosis (PGD)/PGT-A reflecting the particular specialization of the field
Summary
Following the advent of assisted reproduction, clinical embryology has become an evolving field of interest in science. A terminal search could aim to fully capture a topic of research and advance knowledge of a specific field, as well as initiate or resume a debate regarding a current trend such as day-3 versus day-5 embryo transfer or optimal embryo biopsy timing for Preimplantation Genetic Diagnosis (PGD). It may focus on improving understanding of a subject or constitute the primary research work toward drafting a manuscript for publication. Further analysis on collaborations and the trends involved should be of added value as productivity between countries varies significantly This may guide researchers, in vitro fertilization professionals, and prospective authors during literature search, while proving useful regarding manuscript design and concurring on keywords and abstract content
