Abstract: The fertility preservation for those patients with malignant ovarian tumors are often an important problem for clinical doctors, due to more and more late marriage and fewer births, and increasing rate of ovarian cancer. The indications of preserving fertility include Ⅰa borderline ovarian tumor and Ⅰa of G1 malignant epithelial ovarian cancer except for the clear cell carcinoma. Resection of the affected uterine adnexa, and contralateral ovarian biopsy, ascites cytology and peritoneal lymph nodes （pelvic and/or abdominal） dissection or biopsy are basic surgical technique. It is difficult to carry out the randomized controlled study to get conclusive data due to medical ethics. So, there is inconsistency in indications and surgical methods of preserving fertility for those patients with ovarian cancer. On the other hand, with the increasing patients with malignant ovarian tumors, the indication of preserving fertility might be expanded. This paper reviewed these hot issues.
