“…The authors compared attitudes toward organ donation and assisted reproduction in general. They found that more than half of surveyed subjects supported using donated oocytes posthumously for establishing a pregnancy (10). These data are in contrast to a study published in the United Kingdom, in which only 28% of participants found posthumous donation acceptable for purposes of research or treatment (11).…”

“…One such study focused on posthumous donation of female gametes to unknown recipients and found that, among a representative sample of Utah residents, 57% of respondents "were comfortable donating their own or partner's oocytes for fertilization and transfer of the resulting embryos to a couple desiring pregnancy" in the event of death [9]. Another study of couples presenting for their first fertility consultation in New York found that 85% of males and 72% of females "would permit their spouse to harvest their [own] eggs/sperm for the purpose of conceiving a child after their death" [10].…”

Although still exceedingly uncommon, evidence suggests that the prevalence of posthumous sperm retrieval requests for reproductive purposes has increased in recent years within the United States. These requests raise complex issues that pose challenges for physicians, legal scholars, and bioethicists. This study is among the first to examine the general population's attitudes toward posthumous sperm retrieval and, more generally, toward posthumous reproduction. Specifically, the effects of five contextual circumstances-marital status, parental status, wishes of the deceased's parents, context of death, and the wishes of the deceased-on attitudes toward posthumous sperm retrieval for the purpose of cryopreservation and reproduction were examined using a multiple segment factorial vignette with a probability sample of 846 households in the United States. Marital status, disposition of the deceased's parents, and the deceased's wishes affected attitudes in predictable directions, parental status and cause of death had little bearing on attitudes, and respondent religiosity was negatively related to the perceived acceptability of posthumous sperm retrieval as well as medical professional's obligation to perform the procedure.

“…La finalidad de los crioprotectores es mantener la viabilidad celular durante un periodo determinado, previniendo el daño celular durante el proceso de congelación y descongelación, con características tales como: solubles en soluciones acuosas de electrolitos, atravesar las membranas celulares y no ser tóxicos a altas concentraciones (Vincet et al, 1998;Mizukami et al, 1999) El crioprotector no solo está diseñado para la prevención de la criogenesis sino para ayudar a la célula espermática a iniciar la movilidad, subsecuentemente cuando el espermatozoide empieza a mover el flujo de ATP hacia el flagelo con corta duración (Oda y Morisawa, 1993;Ohta et al, 1997).…”

Titulo en ingles: Fish cryopreservation spermatozoa, an approach Silurifomes.RESUMEN: Esta revisión recopila información concerniente a la crioconservación de semen de peces, tomando como base las experiencias realizadas en diferentes especies de bagres. Los siluriformes incluyen géneros con un alto potencial en la acuicultura continental, sin embargo, las investigaciones en este campo son escasas. La introducción de esta metodología en la industria piscícola ha generado beneficios en pro de mejorar la población y la diversificación de especies con destino a una producción comercial. La crioconservación involucra ciertos parámetros en busca de una eficiencia en los protocolos y en procura de disminuir los daños causados por el estrés mecánico y los cambios extremos de temperatura, los cuales inducen una disminución de la población espermática. Los diferentes protocolos de congelación difieren ampliamente en la respuesta postdescongelación en factores como movilidad, estructura y funcionalidad de la célula espermática, características que pueden generar una respuesta adversa en la fertilización de los oocitos, y las cuales son discutidas en este artículo.Palabras claves: crioconservación, crioprotectores, espermatozoide, siluriformes.ABSTRACT: This rev iew compile information concerning to fish semen cryopreservation, based on experiences in different species of catfish. The siluriformes include genera with a high potential for the continental aquaculture. However, the investigations in this field are scarce. The introduction of this method in the fish farming industry has generated benefits in pro of improving the population and the diversification of species with destiny to commercial production. The cryopreservation involves certain parameters in search of efficiency in the protocols and it offers of diminishing the damages caused by the mechanical stress and the extreme temperature changes, which induce a decrease in the sperm population. Different freezing protocols vary widely in answer post-thawed on factors such as motility, structure and function of the sperm cell, factors such as motility, structure and function of the sperm cell, features that may generate an adverse response in the fertilization of oocytes, and which are discussed in this article.Key words: cryopreservation, cryoprotectans, spermatozoa, siluriformes.
