Pulsão de Morte e Sublimação: A (Re)invenção da Vida nas Dobras da Racionalidade Técnico-Científica / Death Drive and Sublimation: The (Re)invention of Life in the Folds of Technical-Scientific Rationality / Pulsión de Muerte y Sublimación: (Re)invención de la Vida en las Doblas de la Técnica

O advento das biotecnologias no mundo contemporâneo, em particular das Novas Tecnologias Reprodutivas (NTR's), liberando a sexualidade dos antigos imperativos da procriação, nos oferece uma prova contundente da abertura ilimitada da vida à transformação das condições em que as normas vitais engajam os organismos no processo de individuação. Mais do que isso, evidencia o caráter essencialmente contingente da ligação entre vida, morte e sexualidade. O objetivo deste trabalho é examinar a fecundidade da concepção freudiana de sublimação - lida sob o registro das transformações que a ela se impõem com o advento do conceito de pulsão de morte (1920) - em subsidiar uma reflexão ética e política acerca dos efeitos da incidência das Novas Tecnologias Reprodutivas (NTR's) nos campos da reprodução, da sexualidade e do laço social. Nossa hipótese é a de que o fenômeno das biotecnologias desvela, sob a cobertura do temor, tão frequentemente evocado por alguns de nossos contemporâneos, de dilapidação das instituições e dos modos de vida sobre os quais acreditávamos poder fundar nossa fantasmática "humanidade", a infinita potência da vida em recriar-se diante d'isso que quer destruí-la.

The advent of biotechnologies in the contemporary world, particularly New Reproductive Technologies (NTRs), freeing sexuality from the old imperatives of procreation, offers us overwhelming proof of the unlimited opening up of life to the transformation of conditions in which vital norms engage the organisms in the individuation process. Even more so, it highlights the essentially contingent character of the connection between life, death, and sexuality. The aim of this study is, therefore, to examine the fruitfulness of the Freudian conception of sublimation, read under the register of the transformations imposed upon this notion with the advent of the death drive concept (1920), in subsidizing an ethical and political reflection on the effects of the incidence of NTRs in the reproduction, sexuality and social bond fields. Our hypothesis is that the biotechnologies phenomenon reveals, under the cover of fear, so often evoked by some of our contemporaries, of institutional dilapidation and ways of life in which we believed we could establish our fantastic "humanity", the infinite life's power to recreate itself in the face of that which wants to destroy it.

Más allá de eso, se evidencia el carácter esencialmente contingente de la ligación entre vida, muerte y sexualidad. El objetivo de este estudio es examinar la fecundidad de la concepción freudiana de sublimación - leída bajo el registro de las transformaciones que a ella se imponen con la llegada del concepto de pulsión de muerte (1920) - en subsidiar una reflexión ética y política acerca de los efectos de la incidencia de las Nuevas Tecnologías Reproductivas (NTR's) en los campos de la reproducción, de la sexualidad y del lazo social. Nuestra hipótesis es que el fenómeno de las biotecnologías desvela, bajo la cobertura del temor, tan frecuentemente evocado por algunos de nuestros contemporáneos, de dilapidación de las instituciones y de los modos de vida sobre los cuales creíamos poder fundar nuestra fantasmática "humanidad", la infinita potencia de la vida en recrearse de ante d'eso que quiere destruirla.

Near-Infrared-Driven Nanorocket for Rapid and Ultrasensitive Detection of MicroRNA.

Herein, by introducing gold nanostars (AuNSs) as fuel core, a near-infrared-driven nanorocket (NIDNR) with pretty fast walking was exploited for ultrasensitive miRNA detection. Compared with traditional nanomaterials-comprised nanomachines (NMs), the NIDNR possesses much better kinetic and thermodynamic performance owing to the extra photothermal driving force from localized surface plasmon (LSP). Impressively, the whole reaction time of NIDNR down to 15 min was realized, which is almost more than 8 times beyond those of conventional DNA-based NMs. This way, the inherent obstacle of traditional NMs, including long reaction time and low efficiency, could be easily addressed. As a proof of concept, the NIDNR was successfully applied to develop an electrochemical biosensing platform for rapid and sensitive detection of miRNA with an LOD down to 2.95 aM and achieved the real-time assay of real biological samples from human hepatocellular carcinoma cells (MHCC97L) and HeLa, thus providing an innovative insight to design more versatile DNA nanomachines for ultimate application in biosensing platform construction and clinical sample detection.

Alterations in the expression pattern of some epigenetic-related genes and microRNAs subsequent to oocyte cryopreservation.

MicroRNAs (miRNAs) are small non-encoding RNAs that actively regulate biological and physiological processes, and play an important role in regulating gene expression in all cells, especially in most animal cells, including oocytes and embryos. The expression of miRNAs at the right time and place is crucial for the oocyte's maturation and the embryo's subsequent development. Although assisted reproductive techniques (ART) have helped to solve many infertility problems, they cause changes in the expression of miRNA and genes in oocytes and preimplantation embryos, and the effect of these changes on the future of offspring is unknown, and has caused concerns. The relevant genomic alterations commonly imposed on embryos during cryopreservation may have potential epigenetic risks. Understanding the biological functions of miRNAs in frozen maturated oocytes may provide a better understanding of embryonic development and a comparison of fertility conservation in female mammals. With the development of new techniques for genomic evaluation of preimplantation embryos, it has been possible to better understand the effects of ART. The results of various articles have shown that freezing of oocytes and the cryopreservation method are effective for the expression of miRNAs and, in some cases, cause changes in the expression of miRNAs and epigenetic changes in the resulting embryo. This literature review study aimed to investigate the effects of oocyte cryopreservation in both pre-maturation and post-maturation stages, the cryopreservation method and the type of cryoprotectants (CPA) used on the expression of some epigenetic-related genes and miRNAs.

Metabolic Mechanisms and Potential Therapeutic Targets for Prevention of Ovarian Aging: Data from Up-to-Date Experimental Studies.

Female infertility and reproduction is an ongoing and rising healthcare issue, resulting in delaying the decision to start a family. Therefore, in this review, we examine potential novel metabolic mechanisms involved in ovarian aging according to recent data and how these mechanisms may be addressed through new potential medical treatments. We examine novel medical treatments currently available based mostly on experimental stem cell procedures as well as caloric restriction (CR), hyperbaric oxygen treatment and mitochondrial transfer. Understanding the connection between metabolic and reproductive pathways has the potential to offer a significant scientific breakthrough in preventing ovarian aging and prolonging female fertility. Overall, the field of ovarian aging is an emerging field that may expand the female fertility window and perhaps even reduce the need for artificial reproductive techniques.

La gestación solidaria, oportunidad reproductiva para las familias cubanas / The solidary gestation, reproductive opportunity for Cuban families i: en

La gestación solidaria es una técnica de reproducción humana asistida, destinada a parejas de distinto o igual sexo y a personas solas con alguna causa de infertilidad que les impide concebir el embarazo de manera natural. Al respecto, en el Código de las Familias en Cuba se esclarece que este proceder solo debe realizarse por motivos altruistas y de solidaridad humana, ajenos a cualquier tipo de honorarios. Teniendo en cuenta las consideraciones anteriores, se analizó el tema desde diferentes puntos de vista, con el objetivo de socializar esta práctica como una oportunidad de reproducción para las familias cubanas.

Solidarity gestation is an assisted human reproductive technique intended for different or same sex couples and to single people with some infertility problems which prevent them from conceiving in a natural way. In this respect, the Cuba's Family Code clarifies that this procedure should only be carried out due to altruistic reasons and human solidarity, without any fees. Taking into account the above considerations, the topic was analyzed from different points of view, aimed at socializing this practice as a reproduction opportunity for Cuban families.

The challenge of assisted reproduction for conservation of wild felids - A reality check.

Threats to the Earth's biodiversity are increasing exponentially, driven by human population growth and resource consumption. As many as one million wildlife species may disappear within the next few decades due to this human-induced extinction event. This represents our current reality and has profound implications for wildlife conservation. Within this context, application of assisted reproductive technology (ART) to conservation management is unlikely to mitigate broad-scale species loss, but for select species, such as wild cats, ART may determine if populations survive or disappear. In North American and European zoos, 20 of the world's 38 wild felid species are managed within structured breeding programs, but most are not sustainable with natural breeding alone. Zoo-based breeding programs are facing tenuous futures due to triage-based responses to this growing sustainability crisis. Theoretically, ART could benefit conservation management, but only by recognizing and addressing its present challenges. The application of ART to wildlife has been rarely successful, with only 62 mammal species (including 15 cat species) ever propagated by AI, and just 35 of these species (6 cats) reproduced following frozen semen AI. Even this most basic form of ART has a minimal impact on wildlife sustainability. The drivers of this deficit include lack of species-specific reproductive knowledge and limited access to animals for study, but also is exacerbated by a science-conservation disconnect that attempts to apply advanced reproductive technologies to species in which basic ART remains unproven. For a few felid species, these scientific challenges have been overcome and AI with frozen semen is becoming feasible as a practical management tool; for other felids, further research is needed. Non-scientific issues also impair our ability to use ART to implement global management plans. Political dysfunction, regulatory barriers and societal indifference create inertia that interferes with achieving meaningful progress in applying ART to wildlife. Collectively, these challenges may seem insurmountable but human resiliency is essential if we are to resolve these issues in a systematic manner. It will require expanding collaborative efforts substantially and intensifying efforts to conserve wildlife species that are literally running out of time. Our goal is to create a new reality that includes a sustainable future for wild felids and other imperiled wildlife species.

Imaginários Morais no Discurso Midiático Sobre o Uso da Inseminação Caseira por Mulheres Lésbicas / Moral Imaginaries on the Media Discourse on the Use of Homemade Insemination by Lesbian Women / Imaginarios Morales en el Discurso Mediático Sobre Uso de la Inseminación Domiciliaria por Mujeres Lesbianas

O presente artigo objetiva refletir sobre o discurso moral midiático produzido em torno da Inseminação Caseira e seu uso como tecnologia reprodutiva por casais de mulheres lésbicas. Esta é uma modalidade reprodutiva autônoma, que consiste em uma autoinseminação de baixo custo, feita com o uso de material biológico de doador não anônimo. Para esta reflexão, utilizou-se cinco obras midiáticas produzidas por canais de comunicação de grande alcance no cenário nacional, analisadas sob a ótica da análise do discurso. Foram traçadas cinco categorias analíticas: apresentação textual-imagética das obras; narrativa das mulheres tentantes; discursos promovidos pelos ditos especialistas; e representação da figura do doador. Conclui-se pela necessidade de estímulo ao debate acerca da inseminação caseira realizada por mulheres lésbicas, de modo que tanto profissionais da área da saúde como a sociedade de uma forma geral não se baseiem apenas em discursos morais condenatórios ditos científicos, como aqueles propagados pela grande mídia em relação à Inseminação Caseira. Soma-se a isso a importância em garantir visibilidade para os relatos das mulheres que estão se submetendo à inseminação caseira, compreendendo-as enquanto protagonistas da produção de sua saúde sexual e reprodutiva e projetos parentais e que, por isso, devem ter seus discursos e experiências legitimados.

The present article aims to reflect on the media moral discourse produced around Homemade Insemination and its use as a reproductive technology by lesbian couples. This is an autonomous reproductive modality, which consists in a low-cost self-insemination performed with the use of biological material from a non-anonymous donor. This reflection was made using five media works produced by communication channels of great reach in the Brazilian scenario, analyzed from the point of view of discourse analysis. Five analytical categories were drawn: textual-imagetic presentation of the works; narrative of women trying to conceive; speeches promoted by the so-called experts; and representation of the donor figure. We conclude that it is necessary to stimulate the debate about homemade insemination performed by lesbian women, so that both health professionals and society in general do not rely only on condemning moral speeches called scientific, such as those propagated by the media in relation to Homemade Insemination. Added to that it is important to ensure visibility of the reports of women who are submitting themselves to homemade insemination, understanding them as protagonists of the production of their sexual and reproductive health and parental projects and that, therefore, they must have their speeches and experiences legitimated.

Se trata de una modalidad reproductiva autónoma, que consiste en una autoinseminación de bajo coste realizada con el uso de material biológico de donante no anónimo. Para esta reflexión, se utilizaron cinco obras mediáticas producidas por canales de comunicación de gran alcance en Brasil analizadas desde la perspectiva del análisis del discurso. Se trazaron cinco categorías analíticas: presentación textual-imagen de las obras; narración de las mujeres que intentan; discursos promovidos por los llamados especialistas; y representación de la figura del donante. Se concluye por la necesidad de estimular el debate sobre la Inseminación Domiciliaria realizada por mujeres lesbianas, de manera que tanto los profesionales de salud como la sociedad en general no se basen apenas en los discursos morales condenatorios de los científicos, como los propagados por la gran prensa sobre Inseminación Domiciliaria. A esto se suma la importancia de garantizar la visibilidad de los relatos de las mujeres que hacen la Inseminación Domiciliaria, entendiéndolas como protagonistas de la producción de su salud sexual y reproductiva y de sus proyectos parentales y debe tener sus discursos y experiencias legitimados.

Analysis of the impact of noninvasive prenatal testing for trisomies 21 and 18 in twin pregnancies undergoing artificial reproductive technology.

PURPOSE: The purpose of this study was to evaluate the performance and impact of noninvasive prenatal screening (NIPS) on twin pregnancies. PATIENTS AND METHODS: Twin pregnancies after artificial reproductive technology(ART) were tested by NIPS for screening trisomy 21, 18, and 13 in a single medical center in Hangzhou. Positive NIPS results were confirmed by karyotyping, while negative results were interviewed after delivery. RESULTS: From January 2019 to December 2020, 474 twin pregnancies were tested by NIPS for screening trisomy 21, 18, and 13 in a single medical center in Hangzhou. The performance of NIPS had been evaluated compared to the invasive diagnostic results. The positive predictive value (PPV) of NIPS for chromosome 21 and 18 aneuploidies is 80% (95CI, 36.09-96.59) and 100%, respectively. The incidence of trisomy 21, and 18 chromosome aneuploidies among the twin pregnancies undergoing ART was 0.84% and 0.21%, respectively. CONCLUSION: The performance of NIPS was substantially accurate among the twin pregnancies after ART in this study, and NIPS potentially avoided a considerable part of aneuploidies liveborn in twin pregnancies in Hangzhou.

Recovering an endangered frog species through integrative reproductive technologies.

The establishment and management of ex situ breeding and assurance populations around the globe are meant to provide short-term solutions to the formidable loss of amphibian diversity presently occurring. Large multi-scaled facilities, such as zoos and aquariums, can provide the infrastructure to safeguard species and populations. However, often even large, economically viable facilities lack the knowledge to efficiently cater to the plethora of environmentally controlled physiological strategies that amphibians possess. Anurans present a class of amphibians that have often been viewed as easy to maintain ex situ. However, while adult survival may be relatively successful it is rarely accompanied by good reproductive output, health, and fitness. Even more conspicuous is the low survivorship of offspring produced ex situ once they are translocated back into the wild. The mountain yellow-legged frog (R. muscosa) ex situ breeding program EBP is a prime example of the challenges that amphibians EBPs face. Although more research is needed, the R. muscosa program has increased reproductive output and health of its colony by incorporating reproductive technologies and strategic genetic management in conjunction with a greater understanding of the species' natural history, to produce and translocate viable animals each year. This paper highlights the EBPs past decade of research featuring the program's contribution to building empirical, multidisciplinary approaches that boost the robustness of an endangered species, by safeguarding existing genetic diversity and maximizing fitness and survival outcomes.

The Pathway of Female Couples in a Fertility Clinic / O percurso de casais homossexuais femininos em uma clínica de fertilidade

Abstract Objective The present study aims to describe the main characteristics of female couples resorting to a fertility clinic, to understand whether these patients have clear previous plans concerning procreation and how they end up completing their family planning, and to briefly describe the main outcomes of the recepción de ovocitos de pareja (ROPA, in the Spanish acronym: in English, reception of partner's oocytes) method. Methods This is a descriptive retrospective study of the pathway and outcomes of female couples in a fertility clinic during a 2-year period. Results A total of 129 couples were treated. Only one third of the couples had no condition potentially affecting fertility or advanced age. Most couples were decided to undergo artificial insemination or in vitro fertilization and the majority kept their plans, as opposed to 38% of the couples who decided to the ROPA method (lesbian shared in vitro fertilization) who changed plans. Live birth rates per treatment (including frozen embryo transfers) for artificial insemination, 58% for in vitro fertilization, 80% for treatments with donated oocytes or embryos, and 79% for ROPA. Four in five couples achieved live births. Conclusion The present study highlights the importance of a thorough medical workup in same-sex couples resorting to assisted reproduction. Despite the higher-than-expected rates of fertility disorders, the outcomes were good. Most couples end up in a single parented method. Furthermore, the results of the ROPA method are reassuring.

Resumo Objetivo O presente estudo tem como objetivo descrever as principais características dos casais femininos que recorrem a uma clínica de fertilidade, perceber se estas pacientes têm planos prévios claros sobre a procriação, como acabam por completar o seu planejamento familiar e descrever sucintamente os principais resultados do método fertilização in vitro compartilhada lésbica (ROPA, na sigla em espanhol). Métodos Trata-se de um estudo retrospectivo descritivo da trajetória e dos resultados de casais femininos em uma clínica de fertilidade durante um período de 2 anos. Resultados Um total de 129 casais foram tratados. Apenas um terço dos casais não apresentava nenhuma condição que afetasse potencialmente a fertilidade ou idade avançada. A maioria dos casais optou pela inseminação artificial ou fertilização in vitro e a maioria manteve seus planos, ao contrário dos 38% dos casais que decidiram se submeter ao método ROPA que mudaram de planos. As taxas de nascidos vivos por tratamento (incluindo transferências de embriões congelados) - 22% para inseminação artificial, 58% para fertilização in vitro, 80% para tratamentos com oócitos ou embriões doados e 79% para ROPA. Quatro em cada cinco casais conseguiram nascidos vivos. Conclusão O presente estudo destaca a importância de um acompanhamento médico em casais femininos que recorrem à reprodução assistida. Apesar das taxas mais altas do que o esperado de distúrbios de fertilidade, os resultados foram bons. A maioria dos casais acaba em um método monoparental. Além disso, os resultados do método ROPA são tranquilizadores.

The limitations of liberal reproductive autonomy.

The common liberal understanding of reproductive autonomy - characterized by free choice and a principle of non-interference - serves as a useful way to analyse the normative appeal of having certain choices open to people in the reproductive realm, especially for issues like abortion rights. However, this liberal reading of reproductive autonomy only offers us a limited ethical understanding of what is at stake in many kinds of reproductive choices, particularly when it comes to different uses of reproductive technologies and third-party reproduction. This is because the liberal framework does not fully capture who benefits from which reproductive options, the extent of the risks and harms involved in various reproductive interventions, and the reasons for why people are driven to make certain reproductive choices.

Fertilizing morality: How religiosity and orientations toward science shape the morality, immorality, and amorality of reproductive technologies.

Scientific innovations continue to advance the possibilities of human reproduction, raising important empirical and ethical questions. In vitro fertilization, disease reproductive genetic technologies, and enhancement reproductive genetic technologies are three reproductive technologies with varying moral support. Instead of assuming moral poles, we use original, nationally representative survey data of US adults (N = 8107) and multinomial logistic regression to examine how religiosity and orientations toward science shape the moral acceptability, amorality, and the moral rejection of in vitro fertilization, disease reproductive genetic technologies, and enhancement reproductive genetic technologies. We find that increased confidence and trust in science lowered the odds of holding moral concerns, while greater religiosity was associated with higher odds of viewing these technologies as morally wrong. Moral attitudes further varied across religious tradition as certain religious groups had significantly higher odds of viewing these technologies as amoral. Findings have implications for advancing understandings of morality around the faith-science interface beyond conceptions of a moral binary.

The European Court of Human Rights and the Emergence of Human Germline Genome Editing.

The field of human germline genome editing (HGGE) offers a promising reproductive potential to prevent inheritance of genetic diseases, yet also opens the door to undesirable eugenics. This stirred the debate about the acceptability of HGGE in light of human rights, particularly human dignity. The European Convention of Human Rights (ECHR) and the European Court of Human Rights (ECtHR) use human dignity as a guiding principle. Therefore, this article examined the clinical implementation of HGGE in light of relevant case-law regarding Article 2 and Article 8 ECHR. The analysis illustrates that the ECtHR broadens the scope of artificial reproductive rights under Article 8, however, Contracting States of the Council of Europe can limit these rights and the accessibility to reproductive techniques, such as HGGE. The ECtHR remains elusive about the legal status of unborn life, but protection under Article 2 with the introduction of HGGE should not be ruled out.

Human Germline Genome Editing: On the Nature of Our Reasons to Genome Edit.

Ever since the publication of Derek Parfit's Reasons and Persons, bioethicists have tended to distinguish between two different ways in which reproductive technologies may have implications for the welfare of future persons. Some interventions harm or benefit particular individuals: they are "person affecting." Other interventions determine which individual, of a number of possible individuals, comes into existence: they are "identity affecting" and raise the famous "non-identity problem." For the past several decades, bioethical debate has, for the most part, proceeded on the assumption that direct genetic modification of human embryos would be person affecting. In this paper, I argue that that genome editing is highly unlikely to be person affecting for the foreseeable future and, as a result, will neither benefit nor harm edited individuals.

Fertility and reproductive technology use in testicular cancer survivors in Japan: A multi-institutional, cross-sectional study.

OBJECTIVE: To evaluate fertility and use of reproductive technology of testicular cancer survivors in a multi-institutional, cross-sectional study. METHODS: This study recruited testicular cancer survivors who were followed after treatment for testicular cancer at eight high-volume institutions between 2018 and 2019. The participants completed the questionnaires on marital status, fertility and use of reproductive technology. RESULTS: A total of 567 testicular cancer survivors, with a median age of 43 years, responded to the questionnaire. Chemotherapy was given to 398 survivors, including three cycles of cisplatin-based chemotherapy in 106 patients and four cycles in 147 patients. Among 153 survivors who attempted sperm cryopreservation, 133 (87%) could preserve sperm. Of the 28 survivors whose cryopreserved sperm was used, 17 (61%) fathered children. Of the 72 survivors who fathered children without the use of cryopreserved sperm, 59 (82%) fathered naturally. Whereas 33 (20%) of 169 survivors treated without chemotherapy fathered children without using cryopreserved sperm, 39 (10%) of 398 treated with chemotherapy fathered children (P < 0.05). Furthermore, the paternity rate was 12% and 5% in testicular cancer survivors with three and four cycles of cisplatin-based chemotherapy, respectively (P < 0.05). However, of 121 survivors who wanted to have children, 14 (12%) received counseling about infertility treatment. CONCLUSIONS: Testicular cancer survivors preserving their sperm have a higher paternity rate after chemotherapy, especially after four cycles, than those not using cryopreserved sperm. Physicians who give chemotherapy for testicular cancer need to take particular care not only with respect to recurrence of testicular cancer, but also to post-treatment fertility.

RUBIC (ReproUnion Biobank and Infertility Cohort): A binational clinical foundation to study risk factors, life course, and treatment of infertility and infertility-related morbidity.

BACKGROUND: Infertility affects 15%-25% of all couples during their reproductive life span. It is a significant societal and public health problem with potential psychological, social, and economic consequences. Furthermore, infertility has been linked to adverse long-term health outcomes. Despite the advanced diagnostic and therapeutic techniques available, approximately 30% of infertile couples do not obtain a live birth after fertility treatment. For these couples, there are no further options to increase their chances of a successful pregnancy and live birth. OBJECTIVES: Three overall questions will be studied: (1) What are the risk factors and natural life courses of infertility, early embryonic loss, and adverse pregnancy outcomes? (2) Can we develop new diagnostic and prognostic biomarkers for fecundity and treatment success? And (3) what are the health characteristics of women and men in infertile couples at the time of fertility treatment and during long-term follow-up? MATERIAL AND METHODS: ReproUnion Biobank and Infertility Cohort (RUBIC) is established as an add-on to the routine fertility management at Copenhagen University Hospital Departments in the Capital Region of Denmark and Reproductive Medicine Centre at Skåne University Hospital in Sweden. The aim is to include a total of 5000 couples equally distributed between Denmark and Sweden. The first patients were enrolled in June 2020. All eligible infertile couples are prospectively asked to participate in the project. Participants complete an extensive questionnaire and undergo a physical examination and collection of biospecimens (blood, urine, hair, saliva, rectal swabs, feces, semen, endometrial biopsies, and vaginal swabs). After the cohort is established, the couples will be linked to the Danish and Swedish national registers to obtain information on parental, perinatal, childhood, and adult life histories, including disease and medication history. This will enable us to understand the causes of infertility and identify novel therapeutic options for this important societal problem.

Affordability and quality of cross-border reproductive care from the perspective of surrogacy mediating agencies in Spain / Asequibilidad y calidad de la atención reproductiva transfronteriza desde la perspectiva de las agencias mediadoras de gestación por sustitución en españa

RESUMEN La gestación por sustitución contribuye a la transformación de las concepciones sociales de la filiación y los cambios en las estrategias reproductivas de las familias. En la presente contribución se relaciona la teoría de la atención reproductiva transfronteriza con las teorías posmodernas de la vida familiar, con el propósito de explorar qué temáticas, elementos y contenidos utilizan las agencias intermediarias de gestación por sustitución que tienen por destinatarios a las madres y padres de intención españoles. Se utiliza la metodología cualitativa y la técnica de análisis de contenido temático tras el registro de la información online recogida de las agencias. Los resultados evidencian el papel de estas agencias mediadoras en los procesos de gestación por sustitución en España, además de generar conocimiento en el área de las nuevas formas familiares constituidas mediante técnicas de reproducción asistida.

ABSTRACT Substitution pregnancy contributes to the transformation of social conceptions of filiation and changes in the reproductive strategies of families. This contribution relates the theory of cross-border reproductive care with post-modern theories of family life in order to explore which themes, elements and contents are used by intermediary surrogate pregnancy agencies which target Spanish mothers and fathers. The qualitative methodology and the technique of thematic content analysis after registration of the online information collected from the agencies is used. The results show the role of these intermediary agencies in the process of gestation by substitution in Spain, as well as generating knowledge in the area of new family forms constituted by assisted reproduction techniques.

Molecular diagnosis of SARS-CoV-2 in seminal fluid.

PURPOSE: Due to relevant repercussions on reproductive medicine, we aimed to evaluate feasibility of RT-PCR as a detection method of SARS-CoV-2 RNA in seminal fluid. METHODS: A qualitative determination of the RT-PCR assays in semen was performed through different approaches: (1) efficiency of RNA extraction from sperm and seminal plasma was determined using PRM1 and PRM2 mRNA and a heterologous system as control; (2) samples obtained by diluting viral preparation from a SARS-CoV-2 panel (virus cultured in Vero E6 cell lines) were tested; (3) viral presence in different fractions of seminal fluid (whole sample, seminal plasma and post-centrifugation pellet) was evaluated. Semen samples from mild and recovered COVID-19 subjects were collected by patients referring to the Infectious Disease Department of the Policlinico Umberto I Hospital - "Sapienza" University of Rome. Control subjects were recruited at the Laboratory of Seminology-Sperm Bank "Loredana Gandini'' of the same hospital. RESULTS: The control panel using viral preparations diluted in saline and seminal fluid showed the capability to detect viral RNA presence with Ct values depending on the initial viral concentration. All tested semen samples were negative for SARS-CoV-2, regardless of the nasopharyngeal swab result or seminal fluid fraction. CONCLUSION: These preliminary data show that RT-PCR for SARS-CoV-2 RNA testing appears to be a feasible method for the molecular diagnosis of SARS-CoV-2 in seminal fluid, supported by results of the control panel. The ability to detect SARS-CoV-2 in semen is extremely important for reproductive medicine, especially in assisted reproductive technology and sperm cryopreservation.
