Objective: To explore the motivations, clinical care, counseling, and support experiences of Australian and New Zealand participants considering or having participated in cross-border reproductive care (CBRC). Design: Questionnaire-based study. Setting: Not applicable. Patient(s): One hundred thirty-seven Australian and New Zealand participants aged 23-53 years. Intervention(s): None. Main Outcome Measures(s): Quantitative and qualitative responses to an anonymously completed online questionnaire. Result(s): Quantitative responses from participants indicated that motivations for engaging in CBRC included limited availability of gamete donors in their home state, difficulty in meeting treatment eligibility criteria, and treatment being legally prohibited. Experiences of CBRC were generally rated positively in terms of medical needs (91.2%), safety (89.4%), and costs (85.7%), although rated more conservatively to emotional needs being met (57.9%). Less than half the sample (47.5%) had accessed some form of CBRC-related counseling. Themes identified in qualitative analysis reflected gamete supply and demand issues, the importance of donor information and disclosure, the personal impact of legislation, and ongoing support needs after CBRC treatment. Conclusion(s): A greater percentage of participants agreed that their CBRC clinic satisfied their overall medical needs and treatment expectations in comparison with overall emotional needs. Participants indicated access to post-treatment support counseling particularly with regard to their emotional well-being and disclosure issues to donor-conceived children would be useful. The implications of our findings for the provision of best-practice psychosocial counseling support and development of counseling guidelines are highlighted. ©2014 by American Society for Reproductive Medicine.

Oxygen concentration during in vitro culture has a significant effect on the physiology of embryos, altering metabolic profile and developmental outcome. Although atmospheric oxygen has been used routinely for the culture of ovarian follicles, oxygen concentration mayalso be critical for follicle growth but the optimal concentration has not been determined. In this study, mechanically isolated primary and secondary follicles (80-140 μm diameter) from adult mouse ovaries were cultured in serum-free conditions for 8 days in either 5 or 20% oxygen to determine growth (follicular diameter), morphology and viability. For each oxygen concentration, half of the mediumwas replaced on Days 2, 4 and 6 or on Day 4 only. In the latter group, metabolic analysis of spent follicular culture media was performed by 1H-NMR. The proportion of viable, growing follicles was significantly (P < 0.0001) higher in 5% than in 20% oxygen (59% versus 8%). Reducing the frequency of medium replacement during culture in 5% oxygen resulted in significantly (P < 0.001) more viable follicles (79 versus 46%). In 20% oxygen, poor follicular viability was observed irrespective of the frequency of medium replacement (8 and 10% respectively). Metabolic profiles showed marked differences in amino acid and carbohydrate utilization with respect to both oxygen concentration and between Days 4 and 8 of development. Metabolites which significantly discriminated between oxygen concentration at both time points were glucose consumption, lactate utilization, alanine, alanyl-glutamine, leucine and proline. In conclusion, the poor in vitro follicular development previously observed in minimal culture conditionsmayreflect the use of 20% oxygen. Frequent medium replenishment is not necessary and does not overcome the detrimental effect of high oxygen on follicle viability. Further optimization of culture conditions would benefit frommetabolic analyses and the use of 5% oxygen should be tested further for impact on functional aspects of follicle culture such as steroid production which is currently unknown. © The Author 2013.

Study question: Is preimplantation genetic diagnosis for aneuploidy (PGD-A) with analysis of all chromosomes during assisted reproductive technology (ART) clinically and cost effective? Summary answer: The majority of published studies comparing a strategy of PGD-A with morphologically assessed embryos have reported a higher implantation rate per embryo using PGD-A, but insufficient data has been presented to evaluate the clinical and cost-effectiveness of PGD-A in the clinical setting. What is known already: Aneuploidy is a leading cause of implantation failure, miscarriage and congenital abnormalities in humans, and a significant cause of ART failure. Preclinical evidence of PGD-A indicates that the selection and transfer of euploid embryos during ART should improve clinical outcomes. Study design, size and duration: A systematic review of the literature was performed for full text English language articles using MEDLINE, EMBASE, SCOPUS, Cochrane Library databases, NHS Economic Evaluation Database and EconLit. The Downs and Black scoring checklist was used to assess the quality of studies. Clinical effectiveness was measured in terms of pregnancy, live birth and miscarriage rates. Participants/materials, settings, methods: Nineteen articles meeting the inclusion criteria, comprising three RCTs in young and good prognosis patients and 16 observation studies were identified. Five of the observational studies included a control group of patients where embryos were selected based on morphological criteria (matched cohort studies). Main results and role of chance: Of the five studies that included a control group and reported implantation rates, four studies (including two RCTs) demonstrated improved implantation rates in the PGD-A group. Of the eight studies that included a control group, six studies (including two RCTs) reported significantly higher pregnancy rates in the PGD-A group, and in the remaining two studies, equivalent pregnancies rates were reported despite fewer embryos being transferred in the PGD-A group. The three RCTs demonstrated benefit in young and good prognosis patients in terms of clinical pregnancy rates and the use of single embryotransfer. However, studies relating to patients of advanced maternal age, recurrent miscarriage and implantation failure were restricted to matched cohort studies, limiting the ability to draw meaningful conclusions. Limitations, reasons for caution: Relevant studies may have been missed and findings from RCTs currently being undertaken could not be included. Wider implications of the findings: Given the uncertain role of PGD-A techniques, high-quality experimental studies using intention-to-treat analysis and cumulative live birth rates including the comparative outcomes from remaining cryopreserved embryos are needed to evaluate the overall role of PGD-A in the clinical setting. It is only in this way that the true contribution of PGD-A to ART can be understood. © The Author 2014.

Aim: To establish the relationships between age, mode of conception and breastfeeding. Method: Consecutive cohorts of nulliparous women >25 weeks pregnant who had conceived through ART (ARTC) or spontaneously (SC) in three age groups ≤30, 31-36 and ≥37 years were recruited. Data were obtained via telephone interviews and postal questionnaires in late pregnancy and 4 months postpartum. Sociodemographic characteristics, reproductive health, birth and breastfeeding experiences were assessed by study-specific questions. Self-rated general health and symptoms of depression and anxiety were assessed with standardized psychometric instruments. Main outcomes were exclusive breastfeeding at discharge from maternity hospital and 4 months postpartum. Results: Of 1179 eligible women, 791 (67%) participated; 549 (93%) had singleton infants, provided complete data and were included in analyses. Overall, 37.2% of participants aged ≤30, 33% aged 31-36 and 55.1% aged ≥37 years experienced Caesarean births. Regardless of age, compared with the SC group, ARTC women had twice the rate of Caesareans prior to labour. Controlling for other factors, exclusive breastfeeding rates at hospital discharge and 4 months postpartum were lowest amongst ARTC women who experienced Caesarean prior to labour (p <.001). Conclusion: Independent of age, assisted conception increases the risk conferred by Caesarean birth to breastfeeding initiation and maintenance. © 2013 Foundation Acta Pædiatrica.

This goal of this study was to compare the outcomes of conventional intracytoplasmic sperm injection (ICSI; control group, n = 53 couples) and a modified ICSI technique using zona pellucida (ZP)-bound sperm for injection of oocytes (test group, n = 53 couples). The proportion of high-quality embryos (grades 1 and 2) and implantation rate were significantly higher in the test group than in the control group, but the difference in fetal heart pregnancy rate was not significant despite seven more pregnancies being obtained in the test group (26 pregnancies) versus the control group (19 pregnancies) following fresh embryo transfers. © 2011 American Society for Reproductive Medicine, Published by Elsevier Inc.
