An increasing number of cancer survivors has overcome cancer with the development of treatments for cancers of children, adolescents, and young adults. On the other hand, the impairment of function caused by cancer treatment has become a problem. In the clinical guidelines for fertility preservation in children, adolescents, and young adult cancer patients published by the Japan Society of Clinical Oncology in 2017, it is noted that cancer treatment is the top priority, but the patient should, as much as possible, be referred to see a doctor who specializes in reproductive medicine when the patient desires to have a child in the future. Myeloablative pretreatment for hematopoietic cell transplantation causes ovarian failure at a high rate. Doctors should understand their impact on fertility and how to preserve fertility and should strive to improve the quality of life of patients after hematopoietic cell transplantation by understanding and using the local oncofertility network.
