This report summarizes the activities of eight subcommittees over 2\u2009years, from 2023 to 2024. These subcommittees addressed various topics, including the review of medical and social indications for oocyte cryopreservation, the current status and challenges of embryo cryopreservation and disposal, the investigation of ovulatory disorders through the HyPO\u2010P classification and a nationwide survey of young women with suspected polycystic ovary syndrome, the revision of polycystic ovary syndrome diagnostic criteria and the development of updated treatment guidelines, the survey of adoption rates of in vitro fertilization add\u2010on treatments following insurance coverage, the national survey on the diagnosis and management of diffuse uterine leiomyomatosis and hereditary leiomyomatosis and renal cell carcinoma, the establishment of a clinical registry system for adenomyomectomy cases, the management of subclinical hypothyroidism in patients with infertility, and the promotion of effective utilization of assisted reproductive technology registry data in Japan. Each subcommittee provides valuable insights into the current status of reproductive medicine in Japan, identifies key challenges, and proposes recommendations to support clinical practice and guideline development. This report will serve as a foundation for advancing reproductive medicine and ensuring high\u2010quality patient care in Japan.<\/jats:p>","DOI":"10.1111\/jog.70008","type":"journal-article","created":{"date-parts":[[2025,7,31]],"date-time":"2025-07-31T04:30:15Z","timestamp":1753936215000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Reproductive
