다국어 초록 (Multilingual Abstract)

This study was conducted to identify the research trends and key concepts of fertility-related research published in Korea. For the analysis of this study, target papers published from 2014 to 2023 were collected by entering the keywords of ‘infertility’ or ‘Sterility’. 155 papers were analyzed. The co-occurrence network of key words was developed and analyzed, and the research trends were examined through topic modeling of the LSD, and visualized word cloud and sociogram were used. The most common key words across the 155 research studies were infertility, infertile women, assisted reproductive technology, women, and depression. Highly connected keywords were the same as the top 5 most frequent keywords, and highly mediated keywords were fertility, infertile women, assisted reproductive technology, bioethics, and low birthrate. The four topics analyzed were identified as ‘infertile women's experiences and care,’ ‘psychological problems of infertile women,’ ‘Korean medicine approaches to infertility,’ and ‘low fertility and fertility procedures’. Based on the results of this study has identified themes and trends in infertility research over the past decade and suggests that future research should focus on intervention studies and policy development for psychological issues related to infertility.
