There is insufficient evidence to recommend any one particular protocol for endometrial preparation over another with regard to pregnancy rates after embryo transfers. These were either frozen embryos or embryos derived from donor oocytes. However, there is evidence of a lower pregnancy rate and a higher cycle cancellation rate when the progesterone supplementation is commenced prior to oocyte retrieval in oocyte donation cycles. Adequately powered studies are needed to evaluate each treatment more accurately.

Purpose Today, male and female adult and pediatric cancer patients, individuals transitioning between gender identities, and other individuals facing health extending but fertility limiting treatments can look forward to a fertile future. This is, in part, due to the work of members associated with the Oncofertility Consortium. Methods The Oncofertility Consortium is an international, interdisciplinary initiative originally designed to explore the urgent unmet need associated with the reproductive future of cancer survivors. As the strategies for fertility management were invented, developed or applied, the individuals for who the program offered hope, similarly expanded. As a community of practice, Consortium participants share information in an open and rapid manner to addresses the complex health care and quality-oflife issues of cancer, transgender and other patients. To ensure that the organization remains contemporary to the needs of the community, the field designed a fully inclusive mechanism for strategic planning and here present the findings of this process. Results This interprofessional network of medical specialists, scientists, and scholars in the law, medical ethics, religious studies and other disciplines associated with human interventions, explore the relationships between health, disease, survivorship, treatment, gender and reproductive longevity.
Purpose To promote nationwide dissemination and implementation of COVID-19 Risk Assessment and Safety Management Operational Guidelines, drawn up by SAMeR Task Force in ART centers in Argentina. Our objective is to prevent and mitigate the transmission of SARS-CoV-2 at an institutional level, while reducing the risk of infection among both physicians and patients in the context of a critical scenario in the local and Latin American healthcare system. Methods SAMeR Executive Committee set up a crisis committee which was made up of specialists in reproductive medicine, embryology, and healthcare management. A critical and updated review of the advances in science, documents, and recommendations released by other societies (ASRM, ESHRE, IFFS, Red LARA, societies of anesthesiologists, infectious diseases, and Occupational Safety and Health Administration-OSHA) was carried out. Likewise, there were joint meetings with the Ministry of Health of Argentina in order to draw up the guidelines. Simultaneously, ongoing medical training was carried out, thus providing added value to them, including two status surveys of the activities of the monovalent and polyvalent centers according to the country's epidemiological mapping. Four additional recommendations were made, and online training was given to healthcare workers. The aforementioned regulations were first analyzed by the healthcare providers and their practical suggestions were then added to the guidelines. Results The one-off collaborative work and the actions coordinated with the National ART Program of the Ministry of Health of Argentina resulted in the development and implementation of the present COVID-19 Risk Assessment and Safety Management Operational Guidelines at a national level. SAMeR gave recommendations for the implementation of the Management Guidelines for the center reopening, providing new safety criteria against the threat of viral contagion. A new organizational culture was promoted through the awareness of all the healthcare workers and teaching responsibility. We continue working on the compliance with a new "Code of Conduct and Commitment in Healthcare" and with workplace safety measures. We helped with transforming the theoretical knowledge into practical measures for the healthcare workers in different services, with the aim to prevent, mitigate, and/or handle contingencies at the centers/services and gamete banks, in line with the actions agreed upon with the Ministry of Health. Conclusions As an extraordinary and uncertain event, the SARS-CoV-2 pandemic helped consolidate a volunteer-based and collaborative panel of SAMeR experts who developed the COVID-19 Risk Assessment and Safety Management Operational Guidelines as a new and readily available tool for physicians, patients, and gamete banks care. Their implementation has provided specific guidelines to minimize risk for professionals in ART clinics, as well as guaranteeing patient safety.
Purpose To compare the effectiveness of starting the ovarian stimulation on the early follicular phase ("Conventional") with the newer range of non-conventional approaches starting in the luteal phase ("Luteal"), random-start, and studies implementing them in DuoStim ("Conventional"+"Luteal"). Methods Systematic review. We searched CENTRAL, PubMed, and Embase, on March 2020. We included randomized and non-randomized controlled trials that compared "Luteal," random-start ovarian stimulation or DuoStim with "Conventional"; we analyzed them by subgroups: oocyte freezing and patients undergoing ART treatments, both, in the general infertile population and among poor responders. ResultsThe following results come from a sensitivity analysis that included only the low/moderate risk of bias studies. When comparing "Luteal" to "Conventional," clinically relevant differences in MII oocytes were ruled out in all subgroups. We found that "Luteal" probably increases the COH length both, in the general infertile population (OR 2.00 days, 95% CI 0.81 to 3.19, moderate-quality evidence) and in oocyte freezing cycles (MD 0.85 days, 95% CI 0.53 to 1.18, moderate-quality evidence). When analyzing DuoStim among poor responders, we found that it appears to generate a higher number of MII oocytes in comparison with a single "Conventional" (MD 3.35, 95%CI 2.54-4.15, moderate-quality evidence). Conclusion Overall, this systematic review of the available data demonstrates that in poor responders, general infertile population and oocyte freezing for cancer stimulation in the late follicular and luteal phases can be utilized in non-conventional approaches such as random-start and DuoStim cycles, offering similar outcomes to the conventional cycles but potentially with increased flexibility, within a reduced time frame. However, more well-designed trials are required to establish certainty.
