The peak incidence of immature teratoma is in the early reproductive period of a woman's life and fertility preservation is an inevitable topic when discussing treatment options. We present two cases of immature teratoma with positive reproductive outcome. Our experience supports the standpoint that surgery alone is curative in most cases, irrespective of tumor grade. Bearing this in mind, the long-term effect of chemotherapy on ovarian function can be avoided and fertility, an important factor in the overall quality of life, can be preserved.
