Although the incidence of the various gynecological cancers has been increasing in recent years, long-term survival is now possible for many patients thanks to advances in multimodality treatment. When treating gynecological cancer in adolescent and young adult (AYA) patients who desire future pregnancy, it is necessary to preserve the reproductive organs and their function to prevent loss of fertility. However, because treatment targets these organs, in the large majority of cases, patients must have these organs removed. In the subfield of oncofertility, treatment of the underlying disease takes priority, and the main principle is preventing delay in treatment. Close cooperation between obstetricians and gynecologists involved in reproductive medicine and oncologists involved in cancer treatment is necessary. In addition, it is important that clinicians work closely not only with other specialists but also with such medical professionals as nurses and counselors so that cancer patients of the AYA generation can be provided the support they need to fight their cancer with hope. Herein, we describe the current status of fertility-sparing therapy for AYA patients with gynecological cancer (cervical cancer, endometrial cancer, or ovarian cancer). In addition, we explain points to keep in mind during a patient's pregnancy after fertility preservation, the latest findings on assisted reproductive technology, and the challenges and prospects of fertility preservation therapy for patients with gynecologic cancer.
