Background: Polycystic ovary syndrome (PCOS) is common and often causes infertility in women of childbearing age. This study adopted the method of bibliometrics to analyze the current research status of research on PCOS and infertility. Method:We conducted a literature search based on the Science Citation Index Expanded (SCI-E) database.All records of search results were exported and the records were cited r in plain text format to generate source files for analysis. CiteSpace software was then used to analyze the source files. The content of the analysis included: annual changes in the number of publications, the distribution of the countries and institutions of the authors of the literature, the distribution of the journals from which the literature was sourced, the distribution of authors, and the use of keywords.Results: There were a total of 2,716 documents retrieved, and the frequency of citations was 86,817.Both the number of documents and the number of citations showed an annually increasing trend. In this field of research, the United States was in a leading position, with many important research institutions and researchers. Emphasis was placed on top-level journals in the field of reproduction and top-level comprehensive journals. The use of keywords changed over time: in recent years, popular keywords included meta-analysis, follicular fluid, oxidative stress, and diagnostic criteria.Conclusions: There are obvious regional differences in PCOS and infertility research. International cooperation, especially cooperation with developing countries, should be strengthened.
