Bibliometric analysis of the links between embryo transfer and endometrial receptivity: Mapping knowledge landscapes and emerging trends (2005-2024).

BACKGROUND

Infertility is a significant global reproductive health challenge with varying prevalence across regions. While assisted reproductive technologies, especially in vitro fertilization, have created new possibilities for treating infertility, embryo transfer success remains limited by multiple factors, particularly endometrial receptivity. Understanding the relationship between embryo transfer and endometrial receptivity is crucial for advancing reproductive medicine and improving infertility treatment outcomes. To address the lack of bibliometric analysis in this field, we conducted a comprehensive bibliometric study of relevant academic literature.

METHODS

We analyzed articles and reviews on endometrial receptivity and embryo transfer from the Web of Science Core Collection using CiteSpace, VOSviewer, and Bibliometrix package. The analysis focused on countries, institutions, journals, authors, keywords, and references.

RESULTS

We identified 1478 documents published over 2 decades, showing an upward trend in annual publications. China led in publication volume, while the USA had the highest citation impact. The University of Valencia and Shanghai Jiao Tong University were the most productive institutions, with fertility and sterility being the leading journal. Simón, C emerged as the most influential author based on publication count and citations. Key research areas included comparing fresh versus frozen embryo transfer, addressing repeated implantation failure, and improving endometrial receptivity. The endometrial receptivity array for personalized embryo transfer represents an emerging research direction in reproductive medicine.

CONCLUSION

This first comprehensive bibliometric analysis of embryo transfer and endometrial receptivity research provides valuable insights into knowledge development, research hotspots, and future directions in the field, serving as a crucial reference for scholars in reproductive medicine.
