AbstractWe report a case of ultrasound-guided ex vivo oocyte retrieval for fertility preservation in a woman with bilateral borderline ovarian tumor, for whom conventional transvaginal oocyte retrieval was deemed unsafe because of the increased risk of malignant cell spillage. Ovarian stimulation with gonadotropins was performed. Surgery was scheduled according to the ovarian response to exogenous gonadotropic stimulation; oophorectomized specimens were obtained by laparoscopy, and oocyte retrieval was performed ∼ 37 hours after the ovulatory trigger. The sum of 20 ovarian follicles were aspirated, and 16 oocytes were obtained. We performed vitrification of 12 metaphase II oocytes and 3 oocytes matured in vitro. Our result emphasizes the viability of ex vivo mature oocyte retrieval after controlled ovarian stimulation for those with high risk of malignant dissemination by conventional approach.

Introduction: Medically assisted reproduction in natural cycle has been investigated, especially in women with poor response to conventional ovarian stimulation, with endometrial receptivity improvement, lower cost and possibility of successive cycles. The disadvantages are: lower profitability per treatment cycle and higher cancellation rate. The aim of this study was to determine the rate of clinical pregnancy in infertile women subjected to medically assisted reproduction in natural cycle.Material and Methods: Retrospective study of 149 medically assisted reproduction without ovarian stimulation of 50 infertile women, between January/2011 and October/2014.Results: The mean age of women undergoing medically assisted reproduction in natural cycle was 36.1 years. Approximately half (46.0%) of the cycles were performed in poor responders. On the day of ovulation trigger, the mean diameter of the follicle was 17.5 mm. Twenty-three cycles (15.4%) were canceled prior to ovulation trigger. In 8 cycles (5.3%), ovulation occurred between ovulation trigger and oocyte retrieval. In the majority of cycles (n = 118; 79.2%) oocyte retrieval was executed, a medically assisted reproduction technique was performed in 71 (47.6%), mostly intracytoplasmic injection. The overall fertilization rate was 77.5%. In 40 cycles (26.8%) there was embryo transfer. The implantation rate and the clinical pregnancy rate by embryo transfer was 35.0% and 25.0%, respectively. Most pregnancies occurred in poor responders, according to Bologna criteria.Discussion: Although the pregnancy rate per cycle started was 6.7%, the rate of clinical pregnancy per embryo transfer is quite satisfactory, being a group of women with unfavorable responses in previous treatments. The relatively high rates of cycle cancellation are mitigated by the greater simplicity and lower cost of these cycles.Conclusion: The results obtained in this study demonstrate that Medically Assisted Reproduction in natural cycle may be an alternative treatment for ovarian stimulation in patients with poor prognosis, whose only alternative would be oocyte donation.

Empty Follicle Syndrome

ABSTRACT Failure to aspirate oocytes from apparently normally growing ovarian follicles with normal steroidogenesis after ovarian stimulation and meticulous follicular aspiration is referred to as empty follicle syndrome (EFS). It is a rare event in in vitro fertilization (IVF), but the economical consequences and emotional frustration of a cancelled cycle are enormous, as it causes substantial stress for both the patients and the treating physician. Here, we have reported one patient of recurrent EFS who had IVF in view of previous failed intrauterine inseminations, with normal male factor. Two cycles of controlled ovarian stimulation were done using antagonist protocol for this patient. However, as we were unable to retrieve any oocytes in both the cycles, we were offered her oocyte donation as the last resort. How to cite this article Punhani R, Shankar K, Varma TR.

Abstract Context: Breast cancer patients undergoing controlled ovarian hyperstimulation (COH) for embryo or oocyte cryopreservation should be induced by the method that leads to the least increase in estradiol (E2) levels. Objective: The aim of the study was to determine the potency of anastrozole to suppress serum E2 levels in breast cancer patients undergoing COH. Design and Setting: A prospective sequential cohort study was conducted in an academic center for reproductive medicine between May 2003 and November 2005 for letrozole and between December 2005 and April 2006 for anastrozole. Patients: Breast cancer patients presenting for fertility preservation participated in the study. Intervention: COH using FSH and letrozole (n = 47) or anastrozole (n = 7) was followed by oocyte retrieval and embryo cryopreservation. Main Outcome Measures: Serum E2 levels, area under the curve for E2, and outcomes of COH cycles were measured. Results: There were no significant differences between the two groups regarding length of stimulation, total gonadotropin dose, number of follicles larger than 17 mm, and the lead follicle size on human chorionic gonadotropin (hCG) day and number of embryos cryopreserved. The mean E2 levels on the day of hCG and post-hCG days were higher in the anastrozole group compared to the letrozole group (1325.89 ± 833.17 and 2515.07 ± 1368.52 vs. 427.78 ± 278.24 and 714.38 ± 440.83 pg·d/ml; P ≤ 0.01), respectively, even when anastrozole dose was increased up to 10 mg/d. The mean area under the curve was significantly higher in the anastrozole group compared to the letrozole group (4402.93 ± 1526.7 vs. 1287.48 ± 732.17 pg·d/ml; P <0.004). Conclusions: Breast cancer patients who underwent ovarian stimulation with anastrozole had a significantly higher exposure to E2 than those who were stimulated with letrozole.
