<p><strong>OBJECTIVE:</strong> To analyze demographic and clinical data of patients who resorted to oocyte freezing between January 2014 and December 2018. </p><p><strong>STUDY DESIGN:</strong> Patients who applied to the Reproductive Endocrinology and Infertility Unit of Ankara University School of Medicine between January 2014 and December 2018 with the request of oocyte freezing were included in this study. The files and computer records of the patients were analyzed retrospectively and sociodemographic, clinical and laboratory data were evaluated. </p><p><strong>RESULTS:</strong> A total of 46 cycles were recorded in 40 patients over a 5-year period. The main indications were low ovarian reserve and/or advanced age (68.3%) and malignancy diagnosis (31.7%). There was a significant difference between elective fertility preservation and oncofertility preservation (Onco-FP) groups in terms of the age (38.4±4.7 vs 28.4±6.1; p=0.001). There was a significant difference between two groups in favor of oncofertility group in terms of anti-Mullerian hormone level, basal follicle-stimulating hormone level, antral follicle count, trigger day estradiol (E2) level, number of obtained oocytes, MII oocytes, and frozen oocytes</p><p><strong>CONCLUSION:</strong> According to our study, the most prominent oocyte cryopreservation indication was advanced age and/or low ovarian reserve. The number of oocytes collected from patients in the Onco-FP group and thus the number of frozen oocytes was significantly higher than in the elective fertility preservation group, due to younger ages and better ovarian reserve in the Onco-FP group. Abdominal administration of the technique is particularly important for virgin patients in our country. Oocyte freezing is a fertility protection method available in a wide range of indications for reproductive-aged women.</p>

Oocyte Freezing

Background: Oocyte Cryopreservation has become an important part of infertility treatment for various reasons such as fertility preservation in women going for oncological treatment; in oocyte donation cycles; in eliminating several religious, ethical, and legal concerns of embryo freezing and in women who wish to delay childbirth. The newer ”vitrification” technique for freezing has further improved the success rates for actual conception than the earlier method of slow freezing. A successful oocyte freezing program can help in establishment of oocyte banks, which would help to provide compatible oocytes immediately, thus would eliminate the several problems of fresh donor cycles. Methods: In this retrospective observational study, total 60 oocyte donation cycles were included (38 were fresh and 22 were vitrified oocytes cycle, respectively). After a thorough screening, controlled ovarian hyperstimulation for donors was performed using flexible antagonist protocol. All mature oocytes were allocated into “vitrified oocytes” and “fresh oocytes” groups. Vitrification technique using Cryotop method was used for oocyte freezing. Both clinical and laboratory outcomes of vitrified and fresh oocytes in donor cycles were compared. Results: A total of 600 oocytes (226 “vitrified oocytes” and 374 fresh oocytes), were studied. After warming 218 oocytes survived resulting in survival rate of 96.4%. Fertilization rate and embryo formation rate was 86.2% and 93.6%, respectively. Results of frozen-thawed oocyte donor cycles were compared with fresh donation cycles. For fresh oocyte group, fertilization rate and embryo formation rate was 83.4% and 92.6%, respectively. On comparing clinical outcomes, clinical pregnancy rate was 60.5% in fresh group and 63.6% in vitrified group. Conclusions: Both clinical and laboratory results obtained in the study suggest that oocyte cryopreservation can be performed with reproducible success, thus vitrification technique can be provided as a useful tool for achieving highly successful outcomes in an oocyte donor program.

ObjectivesAccess to reproductive information and contraception (RIC) continues to be a critical unmet need in Tanzania and impedes the realisation of reproductive health rights. This study examined key sources of RIC and the factors influencing their uptake by women in Mbeya region of Tanzania.SettingThis qualitative study was undertaken in a rural ward in a district in the south of the Mbeya regionParticipantsIn-depth interviews were undertaken with 48 women users and 2 nurses working in a public health facility, and focus group discussions with 16 home-based care workers in the district. Participants were recruited through a local non-governmental organisation (NGO) in the region, and via snowball sampling. All interactions were recorded, translated and transcribed and sought to identify the available resources and barriers in using them.ResultsParticipants reported six main sources of reproductive information and contraceptives: public health facilities, NGO mobile clinics, other women, Mganga wa Asili (witchdoctors/traditional doctors) and Duka la Dawa (pharmacy). Women users and healthcare workers identified a range of individual (age, marital status and geography) and health system-wide factors shaping women’s reproductive choices and preventing uptake of contraceptives. The study also revealed structural factors such as gender, ethnicity, indigeneity as key determinants of access and health seeking, placing women from Sukuma and Maasai communities is the most disadvantageous position. Historical social disadvantage, patriarchal social controls and the pressure to preserve sociocultural traditions that women experience in the Maasai and Sukuma tribes underpin their disconnect from mainstream services.ConclusionWomen’s reproductive choices and their uptake of contraceptives are shaped by the interaction of a range of individual, household, institutional and structural factors. An intersectional lens enables examination of the ways in which these factors interact and mutually constitute disadvantage and privilege.
