Aim: To ascertain the actual outcomes of oncofertility care in young women to provide more appropriate care. Materials & methods: We analyzed the data of 67 female patients under 43 years of age who underwent oncofertility care between January 2015 and September 2019. Results: There were 28 patients with breast cancer, 19 patients with hematologic cancer and 20 patients with other cancer diagnoses. Breast cancer patients tended to take longer than hematologic cancer patients to initiate oncofertility treatment. Despite undergoing oncofertility care, seven of nine pregnant patients did not choose assisted reproductive technology (ART). Conclusion: As spontaneous pregnancies were more common than ART pregnancies in our study, pregnancy by not only ART but also non-ART method is a viable option for young cancer survivors.
