The catastrophic emergency experienced by many countries with the COVID-19 pandemic emphasized the importance of bioethics for decision-making, both at the public health (equitable and effective policies) and at the clinical level. At the clinical level, the issues are the fulfillment of medical care demand with adequate health care teams, infrastructure, and supplies, and to cover critical care demands that surpass the available resources. Therefore, ethically correct approaches are required for the allocation of life sustaining resources. There are recommendations for the allocating life support during disasters based on multiple considerations, including ethical ones. However, the ethical criteria of existing guidelines are variable. Ethical principles usually considered are saving the greatest number of lives, saving the greatest number of years of life and the principle of the life cycle or the goal to give each individual equal opportunity to live through the various phases of life. However, the centrality of the human being and the search for the common good should be considered. Knowledge of public perspectives and moral benchmarks on these issues is essential. A successful assignment effort will require everyone's trust and cooperation. Decision making should be planned and discussed in advance, since in-depth deliberation will be extremely complex during the disaster. Our goal is to help the health care teams to wisely allocate resources in shortage periods.

Objectives: To determine the effectiveness of in vitro maturation (IVM) of oocytes in assisted reproduction. Design: Descriptive study. Setting: Centro de Fertilidad y Ginecología del Sur (CFGS), Cusco, Peru. Participants: Women with diagnosis of infertility. Interventions: In eight women we performed IVM of oocytes, followed by ICSI, culture and vitrification of embryos. Thereafter, patients’ endometrium was prepared and the embryos were thawed and transferred. Main outcome measures: Maturation of oocytes, fertilization, clinical pregnancy and implantation rates. Results: Maturation of oocytes rate was 82.1%, fertilization rate 95.7%, clinical pregnancy 62.5% and implantation rate 29.4%. Conclusion: IVM of oocytes is an effective alternative in assisted reproduction.

Objetivos: Determinar la efectividad de la maduración in vitro (MIV) de ovocitos, como método de reproducción asistida. Diseño: Estudio descriptivo. Institución: Centro de Fertilidad y Ginecología del Sur (CFGS), Cusco, Perú. Participantes: Mujeres con diagnóstico de infertilidad. Intervenciones: Fueron ocho mujeres en las que se realizó MIV de ovocitos, seguido de ICSI, cultivo y vitrificación de embriones. Posteriormente, se preparó el endometrio de las pacientes y se realizó descongelación y transferencia de embriones. Principales medidas de resultados: Tasas de maduración de ovocitos, de fecundación, de embarazo clínico y de implantación. Resultados: La tasa de maduración de ovocitos fue 82,1%, de fecundación 95,7%, de embarazo clínico 62,5% y de implantación 29,4%. Conclusión: La MIV de ovocitos es una alternativa efectiva en reproducción asistida.
