Abstract: Young patients with ovarian malignancies undergoing fertility-sparing surgery(FSS) should be limited to early stage(Ⅰa) with favorable histology, such as high or moderate differentiation, non-clear-cell histology. But for those with advanced stage or unfavorable histology, generally FSS is not recommended. In patients with borderline ovarian tumor, their age is relatively young and most with early stage, after FSS even with ovariocystectomy, the prognosis is not affected. Their fertility outcome is good. In patient with germ cell tumor deal with FSS, most literature reports are dysgerminoma. But for other types of germ cell tumors, or advanced stages, usually FSS is not recommended unless the patient and her family have a strong will. The patients undergoing FSS due to the specific situation is different, the operation should vary from person to person, and individualized.
