Case Report <i>ex Vivo</i>Oocyte Collection to Maintain Fertility in a Patient with Micropapillary Serous Borderline Ovarian Tumor

Background: Approximately 11% of cancer cases are diagnosed in people of childbearing age. Borderline ovarian tumors (BOTs) make up 10%-15% of all ovarian epithelial malignancies. More than one-third of all BOTs occur in women under 40 years of age. Maintaining the fertility of cured patients is the common goal of both oncologists and reproductologists. 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. Due to histopathology, the oncologist recommended re-staging surgery: laparotomy, left salpingo-oophorectomy, omentectomy and hysterectomy. 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.

Intrauterine Insemination—Our Results between the Years 2008-2012

The purpose of this retrospective study was to determine whether or not there was a significant relationship between women’s age as a cause of sterility and pregnancy after IUI. Furthermore, we evaluated the effect of stimulation of antiestrogens and time of hCG administration on the success of IUI in relation to the age of women. During the period between 2008 and 2012, we performed a total number of 793 IUI. Patients were prepared for IUI in the natural cycle and stimulation with antiestrogens (clomiphene citrate-CC). Ovulation was induced by hCG (Ovitrelle) 40 hours before IUI or immediately after the procedure. Sperm was processed through density gradients. The average success rate of IUI was 10.2% of pregnant women per cycle. Significantly the highest number of pregnant women 16.3% was women with a diagnosis of anovulation. Significantly the lowest success rate of IUI was at the immunological cause of infertility and endometriosis. There was no evidence of age dependence for women on the success of IUI. Stimulation of CC did not significantly increase the chance of becoming pregnant. There was also no statistically significant difference in hCG before and after IUI pregnancy success. The most important group of women for whom IUI is a suitable form of assisted reproduction consists of patients of 35 years old with anovulation cause of sterility. Those patients with an immunological cause of infertility and endometriosis have significantly lower chances of conceiving after IUI and it is preferable for them to choose other techniques of assisted reproduction and embryo transfer.
