Global Trends and Collaboration in Ovarian Tissue Transplantation: A 20-Year Bibliometric Analysis.

Ovarian tissue transplantation is vital for preserving fertility in female cancer survivors. Since its first human ovarian tissue transplantation in 2000, and the first live-birth in 2004, it is receiving much more attention. However, the research scale, core research teams, and publication quality have not been systematically documented. This lack of foundational data hinders researchers' ability to assess the maturity and prevailing trends within the domain, potentially leading to duplicated efforts and suboptimal resource allocation. Our study addresses this gap by analyzing ovarian tissue transplantation research from 2000 to 2023 to map academic performance and collaboration networks. Key findings reveal Belgium and the USA as leading contributors, with robust international collaboration driving progress. The Université Catholique Louvain emerged as the most productive institution, while Dolmans M.M. stood out as a pivotal researcher. Human Reproduction ranked as the top journal for disseminating OTT advancements. Research trends highlight sustained focus on "tissue cryopreservation", "activation", and "live-birth" through 2023, with disease indications shifting from "breast cancer" and "chemotherapy" toward "infertility", "leukemia", and "premature ovarian failure". This study offers crucial insights and understanding for the collaboration work of researchers in the field of ovarian tissue transplantation, as well as recommendations for pioneering authors and journal submissions.
