A national survey conducted in 2016 aimed to evaluate the current status and needs of the field of oncofertility and to consider optimized medical delivery systems. A total of 739 oncologists, excluding gynecological and urological specialists, were surveyed. Of these, 99.2% thought that providing information on fertility preservation was important. Of the surveyed oncologists, 48% were affiliated with facilities providing assisted reproductive technology, and 79.3% practiced in university hospitals. Of 238 (32.2%) specialists who provided information on the risk of reproductive damage resulting from treatment in their facility, 163 (44.9%) and 75 (19.9%) practiced in university hospitals (n=363) and non-university hospitals (n= 376), respectively. In contrast, 14.3% and 32.7% of oncologists who practiced in university hospitals and non-university hospitals, respectively, collaborated with local obstetricians and gynecologists. Among oncologists who use a gradually expanding regional oncofertility network, 0.6% practice in university hospitals and 2.7% practice in non-university hospitals. Patients were advised that the risk of infertility was 92.3% and the likelihood of fertility preservation was 66.9%. Furthermore, as an ideal way of providing information on preservation of fertility, 22.9% of oncologists collaborate with local gynecologists, and 26.3% do so at a public cancer and reproductive medical counseling center. In addition, 34.7% and 55.1% of oncologists at university and non-university hospitals, respectively, thought that implementation of a fertility preservation program at a public facility would be desirable. Although most oncologists recognize the importance of providing information on reproductive medicine, the support system for reproductive function and fertility in adolescent and young adult (AYA) generation cancer patients is limited because of the lack of agreement on patient referral. The limited number of referrals in turn limits data collection in the field of oncofertility. Grant: A Health and Labour Sciences Research Grant: H27-Cancer Control-lppan,.
