A bibliometric analysis of polycystic ovary syndrome research in Southeast Asia: Insights and implications

Background and aims: There has been an increased understanding in the pathophysiology and management of polycystic ovary syndrome (PCOS) in recent years. This study aimed to evaluate the trends and characteristics of PCOS publications in Southeast Asia (SEA) through a bibliometric analysis.

Methods: Systematic review of literature on PCOS in SEA countries between 1975 and 2020 was performed using the Scopus database. All published studies on PCOS conducted in or published by authors from any of the countries in SEA were included in this analysis. Bibliographic information was obtained, and visualization of collaboration networks of countries and keywords was conducted using VOSviewer software.

Results: A total of 260 articles were included in this analysis. The number of PCOS publications in SEA continued to increase through the years. The country with the highest number of publications was Thailand while Singapore produced the most publications with the greatest impact. The focus of research in SEA was on PCOS prevalence, risk factors, infertility, and metabolic complications. A country's fertility rate, research and development expenditures (%GDP), number of researchers per million people, and international research collaborations significantly correlated with PCOS research impact in SEA.

Conclusion: This is the first bibliometric analysis in PCOS research in SEA. Despite the continuing increase in PCOS publications in SEA, it still lags compared to other regions. Countries in SEA should consider policies and strategies directed at increasing research support and encouraging international collaborations for local researchers to produce more meaningful publications and augment PCOS knowledge in the region.
