Health Science Research at a Regional Level: Insights From South America Comment on "The Roles of Regional Organisations in Strengthening Health Research Systems in Africa: Activities, Gaps, and Future Perspectives".

The article seeks to shed light on the role of regional organizations in strengthening health research systems in Africa, how they operate and how they work, as well as debts and future challenges. As can be observed also in South America, the continued strengthening of health research requires strategic thinking about the roles, comparative advantages, and capacity of regional organizations to facilitate the flourishing of health research systems. Health research is a strategic field for the transformation of socio-health inequalities on the one hand and the reduction of regional asymmetries on the other. Thus, regional organizations represent key actors in strengthening health research systems and the regional research agenda reinforces its sovereign condition in the autonomous definition of relevant topics and financing. In this process, integration mechanisms face a great challenge, as shown by the recent pandemic, not only in Africa but also in South America.

Tuberculosis en grandes conglomerados urbanos: sentidos y prácticas de abordaje de los equipos de una red de servicios públicos de la Ciudad de Buenos Aires, Argentina

Introducción: la tuberculosis (TB) persiste como un importante problema de salud pública en Argentina con una concentración preocupante en grandes centros urbanos. El objetivo de este estudio es la recuperación de los sentidos y las prácticas del proceso de atención-cuidado de la TB por parte de profesionales en una red pública de servicios de salud de un gran conglomerado urbano. Metodología: se realizó un análisis exploratorio con enfoque cualitativo, a partir de entrevistas semiestructuradas a integrantes de equipos sanitarios en un hospital y en centros de salud de la Ciudad Autónoma de Buenos Aires (CABA). Resultados: se identificaron diferentes matices de sentido acerca de la complejidad en el abordaje de la TB, estos variaban de acuerdo con las características de los servicios y las personas con TB. Se describieron estrategias para el tratamiento de casos difíciles: disponer de equipos interdisciplinarios, involucrar a otros actores de salud y dialogar con organizaciones de la sociedad civil bajo un enfoque territorial. Conclusiones: el control de la problemática de la TB en los grandes conglomerados urbanos presenta amplios desafíos. Desde la perspectiva del personal sanitario, se observan coyunturas que requieren la adecuación de ciertas estrategias interventoras para dar una respuesta de manera integrada.

Introduction: Tuberculosis (TB) persists as an important public health problem in Argentina with a worrying concentration in large urban centers. The objective of this study is to recover the meanings and practices of professionals from a public network of health services in a large urban conglomerate on the TB care-care process. Methods: An exploratory study with a qualitative approach was carried out, based on semi-structured interviews with members of the health teams of a hospital and health centers of the CABA. Results: It was identified that, from the perspective of the health teams, there are different nuances of meaning about the complexity of the TB approach. These varied according to the characteristics of the services in which they were inserted and of the people with TB. Strategies for dealing with complex cases were described: having interdisciplinary teams, acting together with other health effectors and dialoguing with civil society organizations under a territorial approach. Conclusion: The control of the TB problem in large urban conglomerates presents extensive challenges. From the perspective of health teams, complex situations are observed that require the development of certain strategies to address them. These allow the adaptation of interventions to provide an integrated response.

[Infant mortality and social inequalities in Argentina, 1980-2017]. / Mortalidad infantil y desigualdades sociales en Argentina, 1980-2017.

OBJECTIVE: To estimate the trend in infant mortality, inequality between jurisdictions and inequality associated with social conditions in Argentina between 1980 and 2017. METHODS: Ecological and time series study of infant mortality and its inequality. Official data on infant mortality, births and unmet basic needs were obtained; the infant mortality rate, the Gini index and the concentration index were calculated. The trend was also analyzed with a linear regression model and the regression coefficient and its statistical significance were calculated. RESULTS: Infant mortality was reduced by 71.2% (from 32.41 to 9.34 per 1 000 live births). Inequality by jurisdiction also decreased, and the Gini index fell from 0,163 to 0,09. Inequality associated with social conditions also showed a reduction, and the concentration index was reduced from -0.153 to -0.079. Although infant mortality declined throughout the period, this decline was not always accompanied by a reduction in the Gini index and the concentration index. CONCLUSIONS: The trend in the infant mortality rate decreased while the inequality in its distribution by jurisdiction and the inequality associated with social conditions did not always accompany this reduction.

Mortalidad infantil y desigualdades sociales en Argentina, 1980-2017

[RESUMEN]. Objetivo. Estimar la tendencia de la mortalidad infantil, de la desigualdad entre jurisdicciones y de la desigualdad asociada a las condiciones sociales en Argentina entre 1980 y 2017. Métodos. Estudio ecológico y de serie temporal de la mortalidad infantil y de su desigualdad. Se obtuvieron los datos oficiales de mortalidad infantil, de nacimientos y de necesidades básicas insatisfechas; se calculó la tasa de mortalidad infantil, el índice de Gini y el índice de concentración. También se analizó la tendencia con un modelo de regresión lineal y se calculó el coeficiente de regresión y su significación estadística. Resultados. La mortalidad infantil se redujo 71,2% (de 32,41 a 9,34 por 1 000 nacidos vivos). La desigualdad por jurisdicción también se redujo y el índice de Gini pasó de 0,163 a 0,09. La desigualdad asociada a las condiciones sociales también mostró una reducción, y el índice de concentración disminuyó de -0,153 a -0,079. Si bien la mortalidad infantil se redujo en todo el período, este descenso no siempre se acompañó de una reducción del índice de Gini y del índice de concentración. Conclusiones. La tendencia de la tasa de mortalidad infantil fue al descenso mientras que la desigualdad en su distribución por jurisdicción y la desigualdad asociada a las condiciones sociales no siempre acompañaron esa reducción.

Desigualdades sociales, inequidades y enfermedades desatendidas: sífilis congénita en la agenda de salud internacional / Social inequalities, iniquities and neglected diseases: congenital syphilis on the international health agenda / Desigualdades sociais, iniquidades e doenças negligenciadas: sífilis congênita na agenda internacional da saúde

Resumen Objetivo: Identificar el lugar que ocupa la sífilis congénita en la agenda de salud y analizar el proceso de determinación social y los determinantes que, en distintos niveles, influyen para que este tema avance (o no) hacia una agenda de decisión, desde un enfoque del derecho a la salud. Métodos: Estudio cualitativo exploratorio, descriptivo y transversal, basado en datos primarios (entrevistas semi-estructuradas a actores involucrados en la temática del nivel global, regional y local) y secundarios. Se elaboró un modelo para analizar la agenda de salud internacional y la posición que ocupa un tema, en este caso sífilis congénita. Resultados: Determinantes sociales en distintos niveles, vinculados a la política exterior, comercio, ciencia/innovación tecnológica y los sistemas de producción, dificultan el avance de la sífilis congénita desde una agenda formal a una agenda de decisión, sumado a la ausencia de grupos de presión y un bajo grado de visibilidad de la enfermedad como problema. Conclusiones: La sífilis congénita persiste como problema de salud pública. En muchos países de la región no logra pasar a una agenda de decisión, dificultando su efectivo control. El modelo elaborado y los determinantes sociales identificados en sus distintos niveles constituyen un aporte en esta dirección.

Abstract Objective: To identify the place of congenital syphilis on the health agenda and analyze the process of social determination and social determinants having an influence, at different levels, on the health policy agenda setting, from a right to health perspective. Methods: Qualitative exploratory, descriptive and transversal study, based on primary data (semi-structured interviews with those involved in the subject at the global, regional and local level) as well as secondary data. A model was developed to analyze the health agenda and the position that a topic occupies in it, in this case, congenital syphilis. Results: Social determinants, at different levels, linked to foreign policy, trade, science / technological innovation and production systems, hinder the advance of congenital syphilis from a formal agenda to a decision agenda. This process is also influenced by the absence of pressure groups and a low visibility of the disease as a public health problem. Conclusions: Congenital syphilis persists as a public health problem, and in many countries of the region, this issue does not move up to a decision agenda, which hinders its effective control. The elaborated model and the social determinants identified at its different levels constitute a contribution in this direction.

Resumo Objetivo: Identificar o lugar que a sífilis congênita ocupa na agenda da saúde e analisar o processo de determinação social e os determinantes que, em diferentes níveis, influenciam esta questão para avançar (ou não) em uma agenda de decisão a partir de uma abordagem do direito à saúde. Métodos: Estudo qualitativo exploratório, descritivo e transversal, com base em dados primários (entrevistas semiestruturadas com atores envolvidos com o tema em nível global, regional e local) e dados secundários. Foi desenvolvido um modelo para analisar a agenda internacional de saúde e a posição de um problema, neste caso a sífilis congênita. Resultados: Determinantes sociais em diferentes níveis, vinculados a política externa, comércio, ciência / inovação tecnológica e sistemas de produção dificultam o avanço da sífilis congênita de uma agenda formal para uma agenda de decisão, somada a ausência de grupos de pressão e baixa visibilidade da doença como problema. Conclusões: A sífilis congênita persiste como problema de saúde pública. Em muitos países da região, não é possível avançar para uma agenda de decisões, o que dificulta seu controle eficaz. O modelo elaborado e os determinantes sociais identificados em seus diferentes níveis são uma contribuição nessa direção.

Social determinants of pulmonary tuberculosis in Argentina.

BACKGROUND: In Argentina, approximately 9,000 new cases of tuberculosis (TB) are recorded every year, representing an incidence rate of 22 cases per 100,000 inhabitants. There are no reported studies in Argentina examining the factors that influence the unequal distribution of the disease. The aim of the study was to identify the relationship between the distribution of social and economic factors and TB in Argentina between 2008 and 2012. METHOD: An ecologic study involving 525 departmental jurisdictions was conducted. Simple linear regression analysis was performed, followed by multiple linear regression for each group of determinants. A final model of determinants of TB's incidence was constructed from a model of multiple linear regression. RESULTS: The following determinants explain 43% of the variability of TB's incidence rate among different jurisdictions: overcrowding, proportion of households with a sewage network, proportion of examined patients with respiratory symptoms and proportion of patients who discontinued treatment. DISCUSSION: This study makes an important contribution to a better understanding of the factors influencing the TB occurrence in Argentina, which is the result of a multidimensional and complex process. Thesefactors make part of this disease's social determination. CONCLUSION: TB incidence is associated with different determinants, from multiple levels. Inequalities in its distribution in Argentina are driven by the unequal distribution of key social determinants.

RESUMO: Introdução: Aproximadamente 9 mil novos casos de tuberculose (TB) por ano são registrados na Argentina, representando uma taxa de incidência de 22 casos por 100 mil habitantes. Não há estudos publicados que avaliaram os fatores que influenciam a distribuição desigual da doença na Argentina. O objetivo deste trabalho foi identificar a relação entre a distribuição dos fatores sociais e econômicos e da tuberculose na Argentina entre 2008 e 2012. Método: Foi realizado um estudo ecológico envolvendo 525 departamentos. Na análise procedeu-se uma regressão linear simples, seguida de regressão linear múltipla para cada grupo de determinantes. Um modelo final com os determinantes da incidência de TB foi construído por meio de regressão linear múltipla. Resultados: Os seguintes determinantes explicam 43% da variabilidade da taxa de incidência de TB entre diferentes jurisdições: aglomeração intradomiciliar, proporção de domicílios com rede de esgoto, proporção de pacientes examinados com sintomas respiratórios e proporção de pacientes com tratamento descontinuado. Discussão: Este estudo contribui de maneira importante para uma melhor compreensão dos fatores que influenciam a ocorrência da TB na Argentina, resultado de um processo multidimensional e complexo. Esses fatores fazem parte da determinação social dessa doença. Conclusão: A incidência de TB está associada a diferentes determinantes, de múltiplos níveis. A heterogeneidade na distribuição da tuberculose na Argentina deve-se, entre outros fatores, pela distribuição desigual de determinantes sociais e de acesso às ações de saúde.

Building a regional health agenda: A rights-based approach to health in South America.

Attention to health policies in Southern regional organisations reveals a new 'social turn' in the regional political economy of international cooperation. The aims of this paper are twofold. First, it aims to establish the extent to which the Union of South American Nations (UNASUR) has adopted and sustained policy interventions committed to addressing social inequities and asymmetries in relation to health, as indicated by regional policy agendas, policy development processes and resourcing. Second, it seeks to understand how UNASUR is mobilising national and regional actors in support of such policies. Our analysis of documentary sources and interviews leads us to draw the following conclusions. First, we argue that the UNASUR regional framework has a committed social equity/rights focus in relation to access to health care and medicines, with a clear focus on reducing asymmetries between countries. Second, although UNASUR does not enforce national commitments on health and medicines, it nonetheless plays a role in expanding domestic policy horizons and policy capacities. In this respect, we find that UNASUR interventions lead to initiatives and actions aimed at implementing reforms, setting targets and defining goals nationally. Third, in global arena, UNASUR enhances the visibility and 'voices' of the member states.

Determinantes sociales de la mortalidad infantil por causas reducibles en la Argentina, 2009-2011

bjetivo: identificar los determinantes sociales de la mortalidad infantil, según el criterio de reducibilidad, en tres niveles de determinación (individual, familiar y poblacional).Métodos: se realizó un estudio transversal para el análisis de las características de la mortalidad infantil en partidos y departamentos de la República Argentina, y de los determinantes sociales de la mortalidad infantil, en tres niveles de análisis. Para el primero y el segundo nivel, se utilizaron variables relacionadas con los fallecidos que están disponibles en los informes estadísticos de defunción. Para el tercer nivel se utilizaron los datos poblacionales provenientes del Censo Nacional de Población y Viviendas del 2010.Resultados: de los determinantes sociales de la salud considerados, las variables que presentaron asociación estadísticamente significativa con la mortalidad infantil por causas reducibles fueron: edad del fallecido al momento de la muerte, la edad gestacional, lugar de ocurrencia de la muerte, haber tenido atención o no, el nivel de instrucción de la madre, la situación laboral, primaria incompleta y hacinamiento.Conclusión: existe una influencia de factores tanto del nivel individual, como del nivel familiar y poblacional sobre la mortalidad infantil y en mayor proporción sobre las muertes por causas reducibles.

he objective of this project is to identify the social determinants of infant mortality according to the criteria of reducibility and to investigate the association between the infant mortality and its determinants on multiple levels.Methods: A cross-sectional study analyzed the characteristics of infant mortality in parties and departments of Argentina and the social determinants of infant mortality in three levels of analysis.Results: The variables that showed a statistically significant association with infant mortality due to avoidable causes were: age of the deceased at the time of death, gestational age, place of occurrence of death, having attention or not, the level of instruction of the mother, employment status, overcrowding, and incomplete primary care.Conclusions: The factors that influence infant mortality exists as much at an individual level as they do at the family and population levels, and a large proportion of deaths are from preventable causes.

Moving towards South-South International Health: debts and challenges in the regional health agenda.

The aim of this paper is twofold. First, it aims to investigate the increased interest in health as an important dimension of the foreign policy and diplomatic concerns together with the emergence of a new framework for regional health integration and regional health diplomacy. Second, it seeks to understand the role and practices of new regional blocs in the field of health and whether they are conducting to the emergence of new strategies for addressing health regional policies in South America. The regional policy process relates to health as a right. Thus, some practices and processes in social policy are setting new standards for political and social cohesion in the construction of new regionalism. Health crosses national, regional, and global agendas in a multi-directional fashion, rather than via one-way, top-down policy transfer. A special feature of Unasur is upholding regional health sovereignty despite the unique fact that member countries retain national autonomy. Unasur has projected foreign policy that promotes social values in ways that seem innovative. Experience as Unasur shows that regional organisms can become a game changer in global diplomacy and an influential actor in the international agenda. Resumen El objetivo de este artículo es doble. En primer lugar,investigar el creciente interés en la salud como una dimensión importante de la política exterior, en sintonía con el surgimiento de un nuevo marcopara la integración regional y la diplomacia en salud. En segundo lugar, comprender el papel y las prácticas de los nuevos bloques regionales en el campo de la salud y si estasconducena la emergencia de nuevas estrategias para abordar las políticas sanitarias regionales en América del Sur. Los nuevos procesos de integración regional se refieren a la salud como un derecho. Así, algunas prácticas y procesos de la política regional están estableciendo nuevos patrones de cohesión política y social en el avancede un nuevo regionalismo. La salud en este proceso de formulación e implementación de la política regional,atraviesa las agendas nacionales, regionales y globales de forma multidireccional. Un valor agregado de Unasur es su propuesta de avanzar es pos de una mayor soberanía regional en salud, a pesar del hecho de que los países miembros mantienen su autonomía nacional. En este sentido, Unasur ha proyectado una política exterior que promueve principios y valores a partir de un enfoque innovador. El caso de Unasur muestra que los organismos regionales tienen el potencial para cambiar las reglas (y el resultado) del juego en la diplomacia global y convertirse en actores influyentes en la agenda internacional.

Prevalence of tuberculosis respiratory symptoms and associated factors in the indigenous populations of Paraguay (2012)

BACKGROUND The prevalence of respiratory symptoms and confirmed tuberculosis (TB) among indigenous groups in Paraguay is unknown. METHODS This study assessed the prevalence of respiratory symptoms, confirmed pulmonary TB, and associated socio-economic factors among indigenous Paraguayan populations. Indigenous persons residing in selected communities were included in the study. A total of 24,352 participants were interviewed at home between October and December 2012. Respiratory symptomatic individuals were defined as those with respiratory symptoms of TB. A hierarchical Poisson regression analysis was performed with four levels: individual characteristics, living conditions and environmental characteristics, source of food, and type of nutrition. FINDINGS In this study, 1,383 participants had respiratory symptoms (5.7%), but only 10 had culture-confirmed TB (41/100,000 inhabitants). The small number of cases did not allow evaluation of the risk factors for TB. Age older than 37 years was associated with a two-fold increased risk of symptoms. Female sex; family history of TB; type of housing; home heating; a lack of hunting, fishing, or purchasing food; and a lack of vegetable consumption were also associated with the presence of symptoms. A lack of cereal consumption had a protective effect. Members of the Ayoreo or Manjui ethnic groups had a three-fold increased risk of symptoms. MAIN CONCLUSION Individual characteristics, dietary habits, and belonging to specific ethnic groups were associated with respiratory symptoms.

UNASUR Health: A quiet revolution in health diplomacy in South America.

Since the creation of Union of South American Nations (UNASUR), health policies became a strategic factor in South America to collectively balance the legacy of neoliberal policies in the region. The aim of this article is first to describe the social, political, and economic processes that explain the emergence of UNASUR and its focus on social policy through healthcare. We then analyze how by virtue of UNASUR's Health Council, healthcare became the spearhead of cooperation giving way to novel forms of diplomacy. In so doing, this article contributes to a broader understanding of the regional health diplomacy and the process of unasurization of health policies as the process of building a new health framework.

Social determinants of nonadherence to tuberculosis treatment in Buenos Aires, Argentina.

This study aimed to identify the individual and environmental determinants of nonadherence to tuberculosis (TB) treatment in selected districts in the Buenos Aires Metropolitan Area, in Argentina. We conducted a cross-sectional study using a hierarchical model. Using primary and secondary data, logistic regression was performed to analyze two types of determinants. The likelihood of nonadherence to treatment was greatest among male patients. The following factors led to a greater likelihood of nonadherence to treatment: patients living in a home without running water; head of household without medical insurance; need to use more than one means of transport to reach the health center; place of residence in an area with a high proportion of households connected to the natural gas network; place of residence in an area where a large proportion of families fall below the minimum threshold of subsistence capacity; place of residence in an area where a high proportion of households do not have flushing toilets and basic sanitation. Our results show that social and economic factors - related to both individual and environmental characteristics - influence adherence to TB treatment.

El objetivo fue identificar los determinantes individuales y de área de la no adherencia al tratamiento de la tuberculosis (TB) en municipios de Buenos Aires, Argentina. Se realizó un estudio transversal con un modelo jerarquizado. El análisis se llevó a cabo mediante regresión logística múltiple en dos niveles, en base a datos primarios y secundarios. Los varones tuvieron mayor riesgo de no adherencia al tratamiento. La falta de provisión de agua en el hogar aumentó el riesgo de no adherencia. En aquellos hogares cuyo jefe de familia no tenía cobertura de salud también el riesgo de no adherencia fue mayor, al igual que en los pacientes que utilizaron más de un medio de transporte para llegar al centro de salud. En las áreas con mayor proporción de hogares con red de gas natural, mayor proporción de hogares con necesidades básicas instisfechas por la capacidad de subsistencia y mayor proporción de hogares que no tenían inodoros fue mayor el riesgo de no adherencia. Se concluye que los factores sociales y económicos tienen influencia sobre la adherencia al tratamiento, tanto a nivel individual, como de área.

O objetivo deste trabalho foi identificar os determinantes individuais e de área da não-adesão ao tratamento da tuberculose (TB) em municípios de Buenos Aires, Argentina. Foi realizado um estudo transversal com um modelo hierarquizado. A análise dos determinantes foi realizada em dois níveis por meio de análise de regressão logística em dois níveis, com base em dados primários e secundários. Além disso, a falta de abastecimento de água em casa aumentou o risco de não-adesão. Nesses domicílios, cujo chefe de família não tinha a cobertura de saúde, também o risco de não-adesão foi maior, como em pacientes que usaram mais de um meio de transporte para chegar ao centro de saúde. Em áreas com uma maior proporção de domicílios com uma rede de gás natural e com necessidades básicas insatisfeitas para os meios de vida e uma maior proporção de domicílios sem sanitários foi maior o risco de não-adesão. Conclui-se que os fatores sociais e econômicos influenciam a adesão ao tratamento da TB, tanto individualmente como em termos de área.

Spatial analysis of the tuberculosis treatment dropout, Buenos Aires, Argentina.

OBJECTIVE Identify spatial distribution patterns of the proportion of nonadherence to tuberculosis treatment and its associated factors. METHODS We conducted an ecological study based on secondary and primary data from municipalities of the metropolitan area of Buenos Aires, Argentina. An exploratory analysis of the characteristics of the area and the distributions of the cases included in the sample (proportion of nonadherence) was also carried out along with a multifactor analysis by linear regression. The variables related to the characteristics of the population, residences and families were analyzed. RESULTS Areas with higher proportion of the population without social security benefits (p = 0.007) and of households with unsatisfied basic needs had a higher risk of nonadherence (p = 0.032). In addition, the proportion of nonadherence was higher in areas with the highest proportion of households with no public transportation within 300 meters (p = 0.070). CONCLUSIONS We found a risk area for the nonadherence to treatment characterized by a population living in poverty, with precarious jobs and difficult access to public transportation.

Determinants of non adherence to tuberculosis treatment in Argentina: barriers related to access to treatment.

OBJECTIVE: To identify the association between non-adherence to tuberculosis treatment and access to treatment. METHODS: A cross-sectional study was carried out in the Metropolitan Area of Buenos Aires, Argentina. One hundred twenty three patients notified in 2007 (38 non adherent and 85 adherents) were interviewed regarding the health care process and socio-demographic characteristics. Factors associated to non-adherence were assessed through logistic regression analysis. RESULTS: An increased risk of non-adherence with to treatment was found in male patients (OR = 2.8; 95%CI 1.2 - 6.7), patients who had medical check-ups at hospitals (OR = 3.4; 95%CI 1.1 - 10.0) and those who had difficulties with transportation costs (OR = 2.5; 95%CI 1.1 - 5.9). CONCLUSION: Risk of non-adherence increases as a result of economic barriers in accessing health care facilities. Decentralization of treatment to primary health care centers and social protection measures for patients should be considered as priorities for disease control strategies in order to lessen the impact of those barriers on adherence to treatment.

Assisted reproductive outcomes of male cancer survivors.

PURPOSE: The objective of our study was to evaluate the reproductive outcome of male cancer survivors treated with intracytoplasmic sperm injection (ICSI) using cryopreserved sperm and compare it with the same treatment in non-cancer males. METHODS: We retrospectively analyzed database derived from cancer and non-cancer patients undergoing sperm cryopreservation from August 2008 to August 2012 at a university-based center. We evaluated the reproductive outcome of those cancer and non-cancer patients that had frozen sperm and returned subsequently to the clinic for assisted reproduction. RESULTS: We studied 272 males with cancer and 296 infertile males. The most prevalent types of cancer in our cohort were lymphoma (25.3 %), testicular cancer (19.2 %), leukemia (7.3 %), and other malignancies including sarcoma, gastrointestinal, and central nervous system malignancies (48.2 %). The use rate of cryopreserved sperm was 10.7 % for cancer patients and 30.7 % for non-cancer patients. The mean age of males with cancer who returned to the clinic for fertility treatment was 36.7 ± 6 years, and the diagnoses were testis cancer (43.4 %), lymphoma (36.9 %), leukemia (13 %), and other malignancies (6.7 %). Live birth rate of the cancer cohort was 62.1 %, which was higher than that of the normospermic non-cancer population (p < 0.0047). CONCLUSIONS: The use rate of cryopreserved sperm from oncofertility preservation cases is at around 10 %. The live birth rate using assisted reproductive technologies among these patients is at least comparable to that of the non-cancer population. IMPLICATIONS FOR CANCER SURVIVORS: To our knowledge, this was the first comparative study of male cancer survivors treated with ICSI using cryopreserved sperm, which were compared to non-cancer males undergoing the same treatment. Male fertility preservation is a highly valued service that should be strongly encouraged prior to beginning cytotoxic cancer treatment. These results can help healthcare professionals in oncology to improve the quality of counseling on fertility preservation when managing young men with newly diagnosed cancer that require gonadotoxic treatment.
