Aim: Giving young women diagnosed with a prognostically worse type of BOT and after bilateral adnexectomy the possibility to have their genetically own children by the method of ex vivo oocyte collection. Case Presentation: A 34-year-old nulligravid woman with BOT underwent right laparoscopic salpingo-oophorectomy. Histologically, a serious borderline tumor with a micropapillary pattern and a tumor locus on the ovarian surface were found.

The patient refused a hysterectomy as she was planning to get pregnant with her partner. To maintain her fertility, controlled hormonal hyperstimulation and ex vivo aspiration of follicles from the ovary after salpingo-oophorectomy was performed. Ex vivo follicle expiration yielded 10 oocytes. 9 mature oocytes were fertilized by ICSI. The 6 embryos of the highest quality were individually frozen by vitrification. Cryoembryotransfer will be scheduled with the consent of the oncologist. Conclusion: This method is suitable for young women with BOT after bilateral salpingo-oophorectomy in whom ex vivo oocyte collection prevents possible leakage of tumor cells into the abdominal cavity, unlike during the conventional in vivo collection prior to surgery.<span lang="EN-US"><o:p></o:p>展开更多
