Assisted reproduction technologies and reproductive justice in the production of parenthood and origin: Uses and meanings of the co-produced gestation and the surrogacy in Brazil

This article examines the construction of parenthood, drawing on Brazilian cisgender, heterosexual, and homosexual couples' experiences in using assisted reproduction technologies (ART), particularly the surrogacy. For that purpose, we interviewed: 1) a lesbian woman who had her daughter through her partner's pregnancy, using ART with anonymous donor semen; 2) a gay man who, together with his partner, used a surrogacy service under contract via a specialised offshore agency; 3) a woman who was a surrogate, in Brazil, for her sister-in-law and brother who lived abroad and, from abroad, sent an embryo fertilised for surrogacy; 4) a woman who resorted to her sister-in-law in order to be a mother by surrogacy, with ovules from the woman herself fertilised with semen from her husband; and 5) the sister-in-law mentioned in 4), who acted as surrogate for her brother and his wife. These interviews made it possible to think about the discursive construction of the legitimacy of such parenthoods, as it is produced by access to, and manipulation and circulation of, reproductive technologies and persons. This biomedical management of bodies sets up a material and discursive circuit that, in turn, produces a complex web of personal, normative, legal, professional and market relationships, particularly with a view to construction of a parenthood anchored in a notion of biologically-constituted origin. In this respect, biological, affective and social bonds merge to produce a precise placement of who is the father and/or who is the mother, as well as who are the important others and how they are linked to the child in a broader web of parenthood.     

Whose autonomy,whose interests? A donor-focused analysis of surrogacy and egg donation from the global South

This article provides a donor-focused analysis of how transnational reproductive donation intersects with issues central to bodily autonomy of surrogates and egg donors from the global South. Little is known about the autonomy of surrogates and egg donors, especially among those from the global South. This article addresses this gap by examining two key issues on surrogacy and egg donation—conflict of interest and recruitment market. With these issues, this paper presents contexts of the reproductive body as a space of contestation for autonomy. Analysis reveals that bodily autonomy is not an absolute entitlement available for surrogates and egg donors from the global South. Having bodily autonomy is a privileged disposition rather than a universal liberty for reproductive donors. The discussions in this work encourage further examination to understand the multi-layered experiences of reproductive donors from the global South, towards deeper interrogation of the processes of reproductive industry.     

THE ETHICS OF UTERUS TRANSPLANTATION

Human uterus transplantation (UTx) is currently under investigation as a treatment for uterine infertility. Without a uterus transplant, the options available to women with uterine infertility are adoption or surrogacy; only the latter has the potential for a genetically related child. UTx will offer recipients the chance of having their own pregnancy. This procedure occurs at the intersection of two ethically contentious areas: assisted reproductive technologies (ART) and organ transplantation. In relation to organ transplantation, UTx lies with composite tissue transplants such as face and limb grafts, and shares some of the ethical concerns raised by these non‐life saving procedures. In relation to ART, UTx represents one more avenue by which a woman may seek to meet her reproductive goals, and as with other ART procedures, raises questions about the limits of reproductive autonomy. This paper explores the ethical issues raised by UTx with a focus on the potential gap between women's desires and aspirations about pregnancy and the likely functional outcomes of successful UTx.     

CARE ETHICS AND THE GLOBAL PRACTICE OF COMMERCIAL SURROGACY

This essay will focus on the moral issues relating to surrogacy in the global context, and will critique the liberal arguments that have been offered in support of it. Liberal arguments hold sway concerning reproductive arrangements made between commissioning couples from wealthy nations and the surrogates from socioeconomically weak backgrounds that they hire to do their reproductive labor. My argument in this paper is motivated by a concern for controlling harms by putting the practice of globalized commercial surrogacy into the context of care ethics. As I will argue, the unstable situations into which children of global surrogacy arrangements are born is symbolic of the crisis of care that the practice raises. Using the Baby Manji case as my touch point, I will suggest that liberalism cannot address the harms experienced by Manji and children like her who are created through the global practice of assisted reproductive technology. I will argue that, if commissioning couples consider their proposed surrogacy contracts from a care ethics point of view, they will begin to think relationally about their actions, considering the practice from an ethical lens, not just an economic or contractual one.     

The adaptive value of sociality in mammalian groups

According to behavioural ecology theory, sociality evolves when the net benefits of close association with conspecifics exceed the costs. The nature and relative magnitude of the benefits and costs of sociality are expected to vary across species and habitats. When sociality is favoured, animals may form groups that range from small pair-bonded units to huge aggregations. The size and composition of social groups have diverse effects on morphology and behaviour, ranging from the extent of sexual dimorphism to brain size, and the structure of social relationships. This general argument implies that sociality has fitness consequences for individuals. However, for most mammalian species, especially long-lived animals like primates, there are sizable gaps in the chain of evidence that links sociality and social bonds to fitness outcomes. These gaps reflect the difficulty of quantifying the cumulative effects of behavioural interactions on fitness and the lack of information about the nature of social relationships among individuals in most taxa. Here, I review what is known about the reproductive consequences of sociality for mammals.     

How to address the ethics of reproductive travel to developing countries: a comparison of national self-sufficiency and regulated market approaches

One of the areas of concern raised by cross-border reproductive travel regards the treatment of women who are solicited to provide their ova or surrogacy services to foreign consumers. This is particularly troublesome in the context of developing countries where endemic poverty and low standards for both medical care and informed consent may place these women at risk of exploitation and harm. We explore two contrasting proposals for policy development regarding the industry, both of which seek to promote ethical outcomes and social justice: While one proposal advocates efforts to minimize cross-border demand for female reproductive resources through the pursuit of national self-sufficiency, the other defends cross-border trade as a means for meeting the needs of vulnerable groups. Despite the conflicting objectives of the proposed strategies, the paper identifies common values and points of agreement between the two, including the importance of regulations to safeguard those providing ova or surrogacy services.     

Reconstructing feminist perspectives of women’s bodies using a globalized view: The changing surrogacy market in Japan

This paper aims to evoke an alternative viewpoint on surrogacy, moving beyond popular Western feminist beliefs on the practice, by introducing the history and current context of East Asian surrogacy. To elaborate a different cultural perspective on surrogacy, this paper first introduces the East Asian history of contract pregnancy systems, prior to the emergence of the American invention of ‘modern’ surrogacy practice. Then, it examines Japanese mass media portrayals of cross-border surrogacy in which white women have become ‘convenient’ entities. The results of the analysis show how Japanese culture has adopted a rhetoric about the use of white women as convenient surrogate mothers in the global commercial surrogacy market. An essential aspect of surrogacy is the premise that a woman’s reproductive function should be accessible to others. Past discussions among feminists have neglected this important point. Moreover, they share the assumption that white surrogacy clients are exploiters, who take advantage of women of colour as surrogate mothers. The current situation in Asia flips this perspective—with white women regarded as easier targets for exploitation by wealthy people of colour. For Asian clients, Westerners can be easily regarded as ‘others’ whom they can use for their reproductive needs. In today's globalized era, the surrogacy industry is no longer for affluent Westerners only. Considering this change, it is crucial to discuss surrogacy issues by reconstructing feminist perspectives with a globalized view, to help protect women’s bodies, regardless of nationality, ethnicity, skin colour, or religion.     

Effects of within‐colony competition on body size asymmetries and reproductive skew in a social spider

Reproductive partitioning is a key component of social organization in groups of cooperative organisms. In colonies of permanently social spiders of the genus Stegodyphus less than half of the females reproduce, while all females, including nonreproducers, perform suicidal allo‐maternal care. Some theoretical models suggest that reproductive skew is a result of contest competition within colonies, leading to size hierarchies where only the largest females become reproducers. We investigated the effect of competition on within‐group body size variation over six months in S. dumicola, by manipulating food level and colony size. We found no evidence that competition leads to increased size asymmetry within colonies, suggesting that contest competition may not be the proximate explanation for reproductive skew. Within‐colony body size variation was high already in the juvenile stage, and did not increase over the course of the experiment, suggesting that body size variation is shaped at an early stage. This might facilitate task specialization within colonies and ensure colony‐level reproductive output by early allocation of reproductive roles. We suggest that reproductive skew in social spiders may be an adaptation to sociality selected through inclusive fitness benefits of allo‐maternal care as well as colony‐level benefits maximizing colony survival and production.     

The functions of societies and the evolution of group living: spider societies as a test case

Many models have been advanced to suggest how different expressions of sociality have evolved and are maintained. However these models ignore the function of groups for the particular species in question. Here we present a new perspective on sociality where the function of the group takes a central role. We argue that sociality may have primarily a reproductive, protective, or foraging function, depending on whether it enhances the reproductive, protective or foraging aspect of the animal's life (sociality may serve a mixture of these functions). Different functions can potentially cause the development of the same social behaviour. By identifying which function influences a particular social behaviour we can determine how that social behaviour will change with changing conditions, and which models are most pertinent. To test our approach we examined spider sociality, which has often been seen as the poor cousin to insect sociality. By using our approach we found that the group characteristics of eusocial insects is largely governed by the reproductive function of their groups, while the group characteristics of social spiders is largely governed by the foraging function of the group. This means that models relevant to insects may not be relevant to spiders. It also explains why eusocial insects have developed a strict caste system while spider societies are more egalitarian. We also used our approach to explain the differences between different types of spider groups. For example, differences in the characteristics of colonial and kleptoparasitic groups can be explained by differences in foraging methods, while differences between colonial and cooperative spiders can be explained by the role of the reproductive function in the formation of cooperative spider groups. Although the interactions within cooperative spider colonies are largely those of a foraging society, demographic traits and colony dynamics are strongly influenced by the reproductive function. We argue that functional explanations help to understand the social structure of spider groups and therefore the evolutionary potential for speciation in social spiders.     

Online mediations in transnational spaces: cosmopolitan (re)formations of belonging and identity in the Turkish diaspora

Abstract

The lives of transnational groups and individuals are marked by a spatial and imaginary split: a phenomenon wherein identity, belonging and representation have become increasingly elusive concepts, and the realm of the ‘cultural’ vastly important. And, the theoretical compasses of cosmopolitanism and transnationalism are particularly relevant and illuminating in considering social space, mediated communication and belonging in relation to urban diasporic communities and gendered subjectivities. The aim of this paper is to address expressions of identity and belonging at the intersection of online communicative practice and offline spatial formations, with a focus on the specificities of gendered constructions of sociality and subjectivity in the diaspora.     

Views of Swedish Commissioning Parents Relating to the Exploitation Discourse in Using Transnational Surrogacy

Transnational surrogacy, when people travel abroad for reproduction with the help of a surrogate mother, is a heavily debated phenomenon. One of the most salient discourses on surrogacy is the one affirming that Westerners, in their quest for having a child, exploit poor women in countries such as India. As surrogacy within the Swedish health care system is not permitted, Swedish commissioning parents have used transnational surrogacy, and the majority has turned to India. This interview study aimed to explore how commissioning parents negotiate the present discourses on surrogacy. Findings from the study suggest that the commissioning parents’ views on using surrogacy are influenced by competing discourses on surrogacy represented by media and surrogacy agencies. The use of this reproductive method resulted, then, in some ambiguity. Although commissioning parents defy the exploitation discourse by referring to what they have learnt about the surrogate mother’s life situation and by pointing at the significant benefits for her, they still had a request for regulation of surrogacy in Sweden, to better protect all parties involved. This study, then, gives a complex view on surrogacy, where the commissioning parents simultaneously argue against the exploitation discourse but at the same time are uncertain if the surrogate mothers are well protected in the surrogacy arrangements. Their responses to the situation endorse the need for regulation both in Sweden and India.     

Assisted reproductive technology and the risk of pediatric cancer: A population based study and a systematic review and meta analysis

BackgroundThere is controversy whether exposure to assisted reproductive technology (ART) is associated with increased risk of pediatric cancer.We aimed at calculating the overall risk of pediatric cancers after ART in a large cohort of exposed women; and to conduct a systematic review and meta- analysis of cohort studies examining overall risk of pediatric cancers after ART.MethodsAll children born in Israel who were members of Maccabi Health Services (MHS) between 1999 and 2016 after ART, were linked to the Israeli Registry of Childhood Cancer (IGS) to identify those with cancer diagnosed before 16 years of age. In parallel we conducted a systematic review and meta-analysis of observational cohort studies with more than 5000 ART- exposed cases that measured pediatric cancer after ART.ResultsIn the cohort study, the risk ratio for pediatric cancer after ART in general was 0.95 (95% CI, 0.76–1.19). The RR was 1.09 (95% CI, 0.79–1.48) for IVF treatments. Meta- analysis of 13 cohort studies with a total of 750,138 women exposed to ART (with 1152 pediatric cancers) and 214,008,000 unexposed controls (with 30,458 pediatric cancers) did not reveal increased risk for pediatric cancers (RR 0.99; 95% CI, 0.85–1.15).ConclusionsBased on very large numbers, ART in general, and IVF in particular, are not associated with overall increased risk of pediatric cancer.     

Behavioral and endocrine correlates of reproductive failure in social aggregations of captive wolverines (Gulo gulo)

Sociality in mammals is often viewed as a dichotomy, with sociality contrasted against solitariness. However, variation within these broad categories may have strong effects on individual fitness. For example, reproductive suppression of social subordinates is generally associated with group living, but suppression may also occur in solitary species if the behavioral and physiological processes involved can be modulated by the demographic environment. To investigate whether behavioral and physiological traits that normally are associated with group living might be latent even in a solitary species, we explored the level of sociality and investigated causes and mechanisms of reproductive failure in female wolverines Gulo gulo that experienced a highly aggregated social environment in captivity. Behaviorally, females showed low levels of aggression and intermediate levels of social interactions. Reproductive failure seemed to have been related to low social rank and to have occurred between ovulation and implantation in 13 out of 15 breeding attempts. However, three of eight females observed to mate produced offspring, indicating that no individual female fully managed to monopolize breeding. Reproductive failure was not related to elevated levels of glucocorticoid stress hormones. Rather, elevated glucocorticoid levels during the mating season were associated with successful reproduction. We suggest that social tendencies and physiological mechanisms mediating reproductive suppression may be viewed as reaction norms to the social environment. We further suggest that the social flexibility of solitary carnivores might be greater than is commonly observed, due to ecological constraints that may limit aggregation.     

Social systems and life‐history characteristics of mongooses

The diversity of extant carnivores provides valuable opportunities for comparative research to illuminate general patterns of mammalian social evolution. Recent field studies on mongooses (Herpestidae), in particular, have generated detailed behavioural and demographic data allowing tests of assumptions and predictions of theories of social evolution. The first studies of the social systems of their closest relatives, the Malagasy Eupleridae, also have been initiated. The literature on mongooses was last reviewed over 25 years ago. In this review, we summarise the current state of knowledge on the social organisation, mating systems and social structure (especially competition and cooperation) of the two mongoose families. Our second aim is to evaluate the contributions of these studies to a better understanding of mammalian social evolution in general. Based on published reports or anecdotal information, we can classify 16 of the 34 species of Herpestidae as solitary and nine as group‐living; there are insufficient data available for the remainder. There is a strong phylogenetic signal of sociality with permanent complex groups being limited to the genera Crossarchus, Helogale, Liberiictis, Mungos, and Suricata. Our review also indicates that studies of solitary and social mongooses have been conducted within different theoretical frameworks: whereas solitary species and transitions to gregariousness have been mainly investigated in relation to ecological determinants, the study of social patterns of highly social mongooses has instead been based on reproductive skew theory. In some group‐living species, group size and composition were found to determine reproductive competition and cooperative breeding through group augmentation. Infanticide risk and inbreeding avoidance connect social organisation and social structure with reproductive tactics and life histories, but their specific impact on mongoose sociality is still difficult to evaluate. However, the level of reproductive skew in social mongooses is not only determined by the costs and benefits of suppressing each other's breeding attempts, but also influenced by resource abundance. Thus, dispersal, as a consequence of eviction, is also linked to the costs of co‐breeding in the context of food competition. By linking these facts, we show that the socio‐ecological model and reproductive skew theory share some determinants of social patterns. We also conclude that due to their long bio‐geographical isolation and divergent selection pressures, future studies of the social systems of the Eupleridae will be of great value for the elucidation of general patterns in carnivore social evolution.     

The medicalization of "nature" in the "artificial body": surrogate motherhood in Israel

In this article, I draw on anthropological and feminist scholarship on the body and the nature/culture divide as a framework for understanding the place of surrogate mothers in a conceptual ideology that connects motherhood with nature. I explore links between the medicalization of childbirth in Israel and the personal agency of surrogate mothers as relayed through interviews. Taking the patriarchal context of the Israeli surrogacy law of 1996 into consideration, I underscore surrogates' imaginative use of medical metaphors as tools for the subversion of surrogacy's threatening social connotations. By redefining the surrogate body as "artificial" and locating "nature" in the commissioning mother's body, surrogates adopt medical rhetoric to transform surrogacy from a transgressive act into an alternative route toward achieving normative Israeli national reproductive goals.     

Genetic population structure and relatedness in the narrow‐striped mongoose (Mungotictis decemlineata), a social Malagasy carnivore with sexual segregation

Information on the genetic structure of animal populations can allow inferences about mechanisms shaping their social organization, dispersal, and mating system. The mongooses (Herpestidae) include some of the best‐studied mammalian systems in this respect, but much less is known about their closest relatives, the Malagasy carnivores (Eupleridae), even though some of them exhibit unusual association patterns. We investigated the genetic structure of the Malagasy narrow‐striped mongoose (Mungotictis decemlineata), a small forest‐dwelling gregarious carnivore exhibiting sexual segregation. Based on mtDNA and microsatellite analyses, we determined population‐wide haplotype structure and sex‐specific and within‐group relatedness. Furthermore, we analyzed parentage and sibship relationships and the level of reproductive skew. We found a matrilinear population structure, with several neighboring female units sharing identical haplotypes. Within‐group female relatedness was significantly higher than expected by chance in the majority of units. Haplotype diversity of males was significantly higher than in females, indicating male‐biased dispersal. Relatedness within the majority of male associations did not differ from random, not proving any kin‐directed benefits of male sociality in this case. We found indications for a mildly promiscuous mating system without monopolization of females by males, and low levels of reproductive skew in both sexes based on parentages of emergent young. Low relatedness within breeding pairs confirmed immigration by males and suggested similarities with patterns in social mongooses, providing a starting point for further investigations of mate choice and female control of reproduction and the connected behavioral mechanisms. Our study contributes to the understanding of the determinants of male sociality in carnivores as well as the mechanisms of female competition in species with small social units.     

Should Deceased Donation be Morally Preferred in Uterine Transplantation Trials?

In recent years much research has been undertaken regarding the feasibility of the human uterine transplant (UTx) as a treatment for absolute uterine factor infertility (AUFI). Should it reach clinical application this procedure would allow such individuals what is often a much‐desired opportunity to become not only social mothers (via adoption or traditional surrogacy arrangements), or genetic and social mothers (through gestational surrogacy) but mothers in a social, genetic and gestational sense. Like many experimental transplantation procedures such as face, hand, corneal and larynx transplants, UTx as a therapeutic option falls firmly into the camp of the quality of life (QOL) transplant, undertaken with the aim, not to save a life, but to enrich one. However, unlike most of these novel procedures – where one would be unlikely to find a willing living donor or an ethics committee that would sanction such a donation – the organs to be transplanted in UTx are potentially available from both living and deceased donors. In this article, in the light of the recent nine‐case research trial in Sweden which used uteri obtained from living donors, and the assertions on the part of a number of other research teams currently preparing trials that they will only be using deceased donors, I explore the question of whether, in the case of UTx, there exist compelling moral reasons to prefer the use of deceased donors despite the benefits that may be associated with the use of organs obtained from the living.     

Parasitoidism, not sociality, is associated with the evolution of elaborate mushroom bodies in the brains of hymenopteran insects

The social brain hypothesis posits that the cognitive demands of social behaviour have driven evolutionary expansions in brain size in some vertebrate lineages. In insects, higher brain centres called mushroom bodies are enlarged and morphologically elaborate (having doubled, invaginated and subcompartmentalized calyces that receive visual input) in social species such as the ants, bees and wasps of the aculeate Hymenoptera, suggesting that the social brain hypothesis may also apply to invertebrate animals. In a quantitative and qualitative survey of mushroom body morphology across the Hymenoptera, we demonstrate that large, elaborate mushroom bodies arose concurrent with the acquisition of a parasitoid mode of life at the base of the Euhymenopteran (Orussioidea + Apocrita) lineage, approximately 90 Myr before the evolution of sociality in the Aculeata. Thus, sociality could not have driven mushroom body elaboration in the Hymenoptera. Rather, we propose that the cognitive demands of host-finding behaviour in parasitoids, particularly the capacity for associative and spatial learning, drove the acquisition of this evolutionarily novel mushroom body architecture. These neurobehavioural modifications may have served as pre-adaptations for central place foraging, a spatial learning-intensive behaviour that is widespread across the Aculeata and may have contributed to the multiple acquisitions of sociality in this taxon.     

Life-history patterns and sociality in canids: Body size,reproduction, and behavior

Summary Empirical associations among co-adapted traits such as body size and patterns of reproduction, development, and behavior are unknown for most animal species, despite numerous theories suggesting otherwise. One way to study these complex relationships is first to consider closely related species and then to generalize findings to other groups. In the present study, relationships among body size, reproductive patterns, development, and sociality were examined in 17 members of the family Canidae (canids). Large canids are more social than smaller species, and offspring of large species achieve independence and tend to breed first at a later age. Large females give birth to absolutely larger young, but relative to their own body weight they allocate fewer resources to bringing a large pup to term. Overall, sexual dimorphism in size is small to moderate, and this is associated with monogamous mating habits and paternal care of young.     

Communicative roots of complex sociality and cognition

Mammals living in more complex social groups typically have large brains for their body size and many researchers have proposed that the primary driver of the increase in brain size through primate and hominin evolution was the selection pressures associated with sociality. Many mammals, and especially primates, use flexible signals that show a high degree of voluntary control and these signals may play an important role in forming and maintaining social relationships between group members. However, the specific role that cognitive skills play in this complex communication, and how in turn this relates to sociality, is still unclear. The hypothesis for the communicative roots of complex sociality and cognition posits that cognitive demands behind the communication needed to form and maintain bonded social relationships in complex social settings drives the link between brain size and sociality. We review the evidence in support of this hypothesis and why key features of cognitively complex communication such as intentionality and referentiality should be more effective in forming and maintaining bonded relationships as compared with less cognitively complex communication. Exploring the link between cognition, communication and sociality provides insights into how increasing flexibility in communication can facilitate the emergence of social systems characterised by bonded social relationships, such as those found in non‐human primates and humans. To move the field forward and carry out both within‐ and among‐species comparisons, we advocate the use of social network analysis, which provides a novel way to describe and compare social structure. Using this approach can lead to a new, systematic way of examining social and communicative complexity across species, something that is lacking in current comparative studies of social structure.
