Biology is seen not merely as a privileged oppressor of women but as a co-victim of masculinist social assumptions. We see feminist critique as one of the normative controls that any scientist must perform whenever analyzing data, and we seek to demonstrate what has happened when this control has not been utilized. Narratives of fertilization and sex determination traditionally have been modeled on the cultural patterns of male/female interaction, leading to gender associations being placed on cells and their components. (...) We also find that when gender biases are controlled, new perceptions of these intracellular and extracellular relationships emerge. (shrink)

Research over the last decades has stimulated a paradigm shift in biology from assuming fixed and dichotomous male and female sexual strategies to an appreciation of significant variation in sex and sexual behaviour both within and between species. This has resulted in the development of a broader biological understanding of sexual strategies, sexuality and variation in sexual behaviour. However, current introductory biological textbooks have not yet incorporated these new research findings. Our analysis of the content of current biology (...) texts suggests that in undergraduate biology curricula variation in sexual behaviour, sexual strategies and sexuality barely feature, even though sex is discussed in a range of contexts. In this aspect, biological teaching is lagging behind current research. Here, we draw attention to new findings in the biology of sex, and suggest how these might be incorporated in undergraduate teaching to provide a more contemporary and inclusive education for biology students.

The theme of human biology recurs continually both in feminist and in anti-ferminist literature. Reflection on human biology has seemed to promise answers to the urgent questions of why women everywhere are subordinated and whether and how that subordination can be ended. Invariably, anti-feminists have justified women's subordination in terms of perceived biological differences between the sexes, and feminists have responded to their claims in a variety of ways. In this paper, I want to look critically at the (...) ways in which feminists in the liberal and Marxist traditions have responded to the biologically based challenges of anti-feminism, and to suggest an alternative way of conceptualising the relation between human biology and the social status of women.

The Philosophy and Biology of Race and Sex: A Course. Reprinted in Masculinity Lessons: Men, Masculinity, and Women’s and Gender Studies, ed. James Catano and Daniel Novak (Johns Hopkins University Press, 2011).

The first world wide symposium on the topic of gender-specific medicine provided the latest research on differences in sex and/or gender in medicine and medical care. The presentations ranged beyond the topic of reproduction to encompass the entire human organism. This report critically reviews three issues that emerged during the Conference: gender mainstreaming, the concept of sex/gender differences and the issue of men's health. It suggests that the interdisciplinary concept of gender-specific medicine has to be mirrored by the integration of (...) social and cultural studies into medical research and practice. (shrink)

At the turn of the twentieth century, biologists such as Oscar Riddle, Thomas Hunt Morgan, Frank Lillie, and Richard Goldschmidt all puzzled over the question of sexual difference, the distinction between male and female. They all offered competing explanations for the biological cause of this difference, and engaged in a fierce debate over the primacy of their respective theories. Riddle propounded a metabolic theory of sex dating from the late-nineteenth century suggesting that metabolism lay at the heart of sexual difference. (...) Thomas Hunt Morgan insisted on the priority of chromosomes, Frank Lillie emphasized the importance of hormones, while Richard Goldschmidt supported a mixed model involving both chromosomes and hormones. In this paper, I will illustrate how the older metabolic theory of sex was displaced when those who argued for the relatively newer theories of chromosomes and hormones gradually formed an alliance that accommodated each other and excluded the metabolic theory of sex. By doing so, proponents of chromosomes and hormones established their authority over the question of sexual difference as they laid the foundations for the new disciplines of genetics and endocrinology. Their debate raised urgent questions about what constituted sexual difference, and how scientists envisioned the plasticity and controllability of this difference. These theories also had immediate political and cultural consequences at the turn of the twentieth century, especially for the eugenic and feminist movements, both of which were heavily invested in knowledge of sex and its determination, ascertainment, and command.

In this article, we argue that there is an essential difference between social intelligence and creative intelligence, and that they have their foundation in human sexuality. For sex differences, we refer to the vast psychological, neurological, and cognitive science research where problem-solving, verbal skills, logical reasoning, and other topics are dealt with. Intelligence tests suggest that, on average, neither sex has more general intelligence than the other. Though people are equals in general intelligence, they are different in special forms of (...) intelligence such as social intelligence and creative intelligence, the former dominant in women, the latter dominant in men. The dominance of creative intelligence in men needs to be explained. The focus of our research is on the strictly anthropological aspects, and consequently our explanation for this fact is based on the male-female polarity in the mating systems. Sexual dimorphism does not only regard bodily differences but implies different forms of sex life. Sex researchers distinguish between two levels of sexual intercourse: procreative sex and recreational sex, and to these we would add “creative sex.” On all three levels, there is a behavioral difference between men and women, including the subjective experience. These differences are as well attributed to culture as genetically founded in nature. Sexual reproduction is only possible if females cooperate. Their biological inheritance makes females play a decisive role in mate choice. Recreational sex for the purpose of pleasure rather than reproduction results from female extended sexual activity. Creative sex, on the contrary, is a specifically male performance of sexuality. We identify creative sex with eroticism. Eroticism evolved through the transformation of the sexual drive into a mental state of expectation and fantasizing. Hence, sex differences (that nowadays are covered up by cultural egalitarianism) continue to be the evolutionary origin of the difference between social and creative intelligence. (shrink)

Biomedical and social scientists are increasingly calling the biological sex into question, arguing that sex is a graded spectrum rather than a binary trait. Leading science journals have been adopting this relativist view, thereby opposing fundamental biological facts. While we fully endorse efforts to create a more inclusive environment for gender‐diverse people, this does not require denying biological sex. On the contrary, the rejection of biological sex seems to be based on a lack of knowledge about evolution and it champions (...) species chauvinism, inasmuch as it imposes human identity notions on millions of other species. We argue that the biological definition of the sexes remains central to recognising the diversity of life. Humans with their unique combination of biological sex and gender are different from non‐human animals and plants in this respect. Denying the concept of biological sex, for whatever cause, ultimately erodes scientific progress and may open the flood gates to “alternative truths.”. (shrink)

The Phenomenology of Sex, Love, and Intimacy presents a phenomenological exploration of love as it manifests itself through sexual desires and intimate relationships. Setting up a unique dialogue between psychology and philosophy, Susi Ferrarello offers a perspective through which clinicians can inform their practice on diverse issues of human sexuality. Drawing on Husserl's phenomenology, Ferrarello's analysis of love spans a range of disciplines including psychology, theology, biology, epistemology, and axiology, as well as areas related to gender, consent, and political (...) control. Combining Husserlian perspectives on ethics with a focus on lived-experience, this text will deepen therapists' understanding of love as the subject of interdisciplinary inquiry and enable them to locate questions of sexuality and intimacy within an academic framework. With key theoretical principles included to allow clinicians to think through and clarify their practice, this book will be a valuable tool for sex therapists, marriage and family therapists, and counselors, as well as psychology and philosophy students alike.

Scientists’ identities and social locations influence their work, but the content of scientific work can also influence scientists. Theory from feminist science studies, autoethnographic accounts, interviews, and experiments indicate that the substance of scientific research can have profound effects on how scientists are treated by colleagues and their sense of belonging in science. I bring together these disparate literatures under the framework of professional cultures. Drawing on the Survey of Earned Doctorates and the Web of Science, I use computational social (...) science tools to argue that the way scientists write about sex in their research influences the future gender ratio of PhDs awarded across 53 subfields of the life sciences over a span of 47 years. Specifically, I show that a critical paradigm of “feminist biology” that seeks to de-essentialize sex and gender corresponds to increases in women’s graduation rates, whereas “sex difference” research—sometimes called “neurosexism” because of its emphasis on essential, categorical differences—corresponds to decreases in women’s graduation rates in most fields.

Abstract:This article examines how two American theorists, Gayle Rubin and Judith Butler, deploy geologic language during the 1990s moment when their feminist careers morphed into queer careers. I argue that the precise composition of this institutional shift – methodological, material, and epistemological – is both reflected and refracted in the figure of the rock. A symbol that connotes fixity in short time spans, but dynamism in long ones, the rock oscillates between facticity and dissolution, mirroring shifting notions of sex and (...) gender in the 1990s. In her retrospective account of the emergence of queer theory, Rubin’s use of a fossil metaphor ushers the field toward a non-reproductive and non-procreative genealogy, illuminating a different temporal texture to such seemingly fixed structures as sex, gender, and sexuality. Butler’s inherited geologic language conceives of gender as the process of sedimentation that resists the biological determinism of identity-based feminist politics. Examining the rock provides crucial readings of Butler’s materiality, one that oscillates between fixed being and dynamic becoming, stability and change, surface signification and depth excavation.

The evolutionary maintenance of sexual reproduction is a case of explanatory pluralism of central importance to evolutionary biology. I analyze this pluralism from an epistemological perspective. My thesis is that the various explanations of sex are explanatory by virtue of local factors and hence are importantly distinct from one another and cannot be subsumed under a single unifying framework. A critic may argue that philosophical accounts of mechanism can provide just such a framework. I show that this attempt at (...) unification fails because the accounts of sex are not explanatory simply in light of being their being mechanistic; rather they are explanatory because they are particular kinds of mechanisms. The explanatory power of a mechanism is dependent on its epistemological context and the contexts of these mechanisms differ. (shrink)

Is the history of life a series of accidents or a drama scripted by selfish genes? Is there an “essential” human nature, determined at birth or in a distant evolutionary past? What should we conserve—species, ecosystems, or something else? -/- Informed answers to questions like these, critical to our understanding of ourselves and the world around us, require both a knowledge of biology and a philosophical framework within which to make sense of its findings. In this accessible introduction to (...) philosophy of biology, Kim Sterelny and Paul E.

Operations on intersexuals indicate that the sex of a person is based on more than biology. Expectations about proper gender activities furnish the frameworks through which certain features and combinations of features are understood to be fundamental to bodies and to comprise their sex. Yet, we can ask whether this interpretation is either coherent or consistent with our fuller conceptions of ourselves. Is there a point to interpreting a person as a sex?

Biological traits, the foci of natural selection, are by definition emergent from the genes, proteins, and other “nothing-buts” that constitute them. Moreover, and with the exception of recently emergent “spandrels,” each can be accorded a teleological dimension—each is “for” some purpose conducive to an organism's continuation. Sex, which is “for” the generation of recombinant genomes, may be one of the most ancient and ubiquitous traits in biology. In the course of its evolution, many additional traits, such as gender and (...) nurture, have emerged. Patterns of sexual exchange are the basis for patterns of biological evolution and are central to the process of eukaryotic speciation. Human sexuality is central to our selves. (shrink)

Using computer simulations I studied the simultaneous effect of variable environments, mutation rates, ploidy, number of loci subject to evolution and random and assortative mating on various reproductive systems. The simulations showed that mutants for sex and recombination are evolutionarily stable, displacing alleles for monosexuality in diploid populations mating assortatively under variable selection pressure. Assortative mating reduced excessive allelic variance induced by recombination and sex, especially among diploids. Results suggest a novel adaptive value for sex and recombination. They show that (...) the adaptive value of diploidy and that of the segregation of sexes is different to that of sex and recombination. The results suggest that the emergence of sex had to be preceded by the emergence of diploid monosexual organisms and provide an explanation for the emergence and maintenance of sex among diploids and for the scarcity of sex among haploid organisms.

Discussions of the implications of sexual reproduction have appeared throughout the history of evolutionary biology, from Darwin to Weismann, Fisher, Muller, Maynard Smith, and Williams. The latest of these appearances highlighted an evolutionary paradox that had previously been overlooked. In many animal and plant species reproduction is obligately sexual and also half the offspring are male, yet the males contribute nothing but genes to reproduction. If asexual mutants of such a species were to produce as many asexual offspring on (...) average as sexual females in that species produce daughters and sons, the growth rate of their population would be twice as large. Whereas half the offspring of sexual females are noncontributory males, all the offspring of such an asexual mutant would contribute to growth rate. Nevertheless, sexual reproduction prevails in most species and is not lost evolutionarily. (shrink)

Previous studies have emphasized a person’s biological sex as a factor which influences online search behavior. This study aims to investigate how people search online for political information and if gendered online search exists. We examined online search behavior via eye tracking while the participants searched for information about political party positions on the Internet. A content analysis of the eye tracking data followed and was evaluated with a special focus on the role of biological sex and social gender, and (...) the relationship of both factors with other variables, such as self-reported prior political knowledge, political interest, and Internet skills. The results accord with previous studies in that the sex influences the online search process. However, this relationship was partially mediated by self-reported political interest and prior knowledge. This outcome calls for a more critical use of the sex variable in reference to political online search behavior, and the inclusion of sex and gender related variables. (shrink)

The evolution of sexual reproduction is a striking case of explanatory pluralism, meaning that one needs to refer to more than one explanation in order to adequately account for it. I develop the concept a domain of phenomena in order to analysis this pluralism. Pluralism exists when a phenomenon can be included in more that one homogeneous domain or in a heterogeneous domain. I argue that in some cases domain partitioning can be used to decrease pluralism, but that in the (...) case of sex domains are overlapping and interconnecting, or in other words bear an orthogonal relationship to one another, and hence cannot be partitioned in such a way as to eliminate pluralism.

Gender identity is ill-suited as a basis for non-discrimination protections, as proposed in the 2019 Equality Act. Biological sex provides a clearer and better means to the same laudable end.

Despite the controversial nature of studies of reproductive phenomena, a major center of reproductive biology emerged and coalesced in the Department of Zoology at the University of Chicago circa 1892–1940. Led by Frank R. Lillie, several small groups of researchers pioneered the study of sex determination and sex hormones, pursuing these via a Chicago approach to framing biological practice at both cellular and organismic levels. They worked in an interdisciplinary manner, however much in tandem, and drew strongly on local (...) resources—from the stockyards to local philanthropy. Most remarkably, Lillie redirected the mission of the major National Research Council Committee for Research Problems of Sex to address the biology of sex and then garnered about a fifth of its funds for Chicago. He thus guided Chicago biology into the fully modern era of external support for on-campus research and elaborate national scientific networks via promising biological solutions to social problems.

Anatomy texts are seen as authoritative sources for knowledge about natural sex differences. The concepts of a natural, biological sex and of a natural difference are, however, increasingly difficult to sustain. A growing number of scholars have pointed to the fact that `sex' as much as `gender' is a historical and social construction. This article examines how the multiple-edition anatomy textbook, Gray's Anatomy, has portrayed the sexed body and male/female differences during the course of its publication, 1858 to the present, (...) focusing on specific parts of the anatomy, namely the sex organs or `organs of generation', the pelvis, the skull and the brain. An analysis of textual descriptions and graphic illustrations reveals that the male body has been the stable norm or standard against which the female body has been compared and implicitly judged as underdeveloped, weak or faulty. Only rarely has the male body been compared with the female body. Reflecting long-standing views about sexual complementarity and natural differences between men and women, some comparisons emphasize the reproductive functioning of females or imply that females are intellectually inferior. It would appear that the discipline of anatomy has remained largely immune from broader public debates about sexual inequality and gender representations. (shrink)

Several decades ago, feminists differentiated between the biologically given basis of sex identity (sex) and the socially constructed cultural practices anchored by sex identity (gender). In recent years, many feminists have challenged that distinction, arguing that biological sex is as much a social construct as are the practices comprising gender. I survey two examples from biological studies of sex identity that, by contrast (I maintain), warrant saving the concept of biologically given sex identity. The result is not antithetical to feminism, (...) however, since these studies also suggest that sex identity proliferates beyond the rigid female/male dichotomy. If articulated carefully, this view can avoid metaphysically essentialist baggage while enriching feminist conceptions of sex identity. (shrink)

The aim of this study is to undertake an in-depth conceptual and ethical analysis of African philosophy of sex and the HIV/AIDS epidemic in Africa by taking the Oromo of Ethiopia as an example. The continent with just 10% of the world’s population is home to over 70% of the world’s HIV/AIDS infection. HIV/AIDS is a social, economic, demographic and moral problem as well as a health care issue. Some scholars hypothesise that the unique nature of African sexuality, sexual promiscuity, (...) the prevalence of other ailments, and the unique nature of the viral subtypes (known as clades) are the major reasons for Africa’s AIDS prevalence. However, there is little substance to their hypotheses. As of today there is no sound explanation for the prevalence of HIV/AIDS in Africa. So far the HIVintervention has largely focused on behaviours, systems and structures which are visible without fully taking into account culture, values, norms and traditions which are invisible but have a strong influence on visible aspects of individual behaviours and societal structures. Thus, this issue requires further research into people’s philosophy of sex and indigenous moral values. This study and the contributions of many scholars have shown that Africans have a diverse spectrum of sexual behaviour ranging from the very restrictive to the permissive. Although some ethnic groups have developed a profound philosophy of ex that can curb the expansion of HIV/AIDS, there have been some sexual and religious norms and expectations in Africa that have contributed to the rapid spread of HIV/AIDS. Social, economical, and political forces have also shaped the HIV/AIDS epidemic. This paper thus suggests that global fight against HIV/AIDS should go beyond a narrow focus on the behavioural and biological, and consider broader structural and underlying factors such as poverty, homelessness, widespread sex work, rural to urban migration, instability, a high rate of unemployment, unequal gender relations, harmful traditional practice and global injustice that have facilitated the spread of HIV/AIDS. African governments should involve the local people and civil society organisations in the fight against HIV/AIDS by using a wide range of participatory methodologies and culturally sensitive advocacy strategies. This study thus suggests that a multi-faceted approach is needed to deal with the challenges of the 21st century and address the HIV/AIDS epidemic in our world.

Understanding how complex sexual reproduction arose, and why sexual organisms have been more successful than otherwise similar asexual organisms, is a longstanding problem in evolutionary biology. Within this problem, the potential role of endosymbionts or intracellular pathogens in mediating primitive genetic transfers is a continuing theme. In recent years, several remarkable activities of mitochondria have been observed in the germline cells of complex eukaryotes, and it has been found that bacterial endosymbionts related to mitochondria are capable of manipulating diverse (...) aspects of metazoan gametogenesis. An attempt is made here to rationalize these observations with an endosymbiotic model for the evolutionary origins of sex. It is hypothesized that the contemporary life cycle of germline cells has descended from the life cycle of the endosymbiotic ancestor of the mitochondrion. Through an actin‐based motility that drove it from one cell to another, the rickettsial ancestor of mitochondria may have functioned as a primitive transducing particle, the evolutionary progenitor of sperm.

This chapter argues that a Peircean philosophy of sex offers a non-reductionist approach to sex as a biological category. The chapter surveys traditional biological accounts of sex categories and several social constructivist accounts of sex. It then provides an overview of Peirce’s scholastic realism and his ethics of inquiry. While Peirce regarded the distinction between the sexes as a rare “polar distinction”, the chapter works to recover the nuanced view of sex that Peirce ought to have adopted had he extended (...) his scholastic realism to reproductive biology. Ultimately, the Peircean account offered treats sex differences as norms expressed as bimodal distributions. The chapter concludes by illustrating some applications of this Peircean philosophy of sex, and gesturing to those that we can yet barely imagine. (shrink)

In this critical, feminist account of the management of intersex conditions under 2006's controversial “Disorders of Sex Development” (DSD) treatment model, I argue that like the “Optimal Gender of Rearing” (OGR) treatment model it replaced, DSD aims at securing a cisgendered future for the intersex patient, referring to a normalized trajectory of development across the lifespan in which multiple sexed, gendered, and sexual characteristics remain in “coherent” alignment. I argue this by critically analyzing two ways that intersex management has changed (...) between OGR and DSD: 1) regarding sex‐assignment recommendations for three patient populations and, 2) with the prenatal treatment of pregnant individuals at risk of conceiving a fetus with congenital adrenal hyperplasia with the steroid hormone dexamethasone. I conclude that like OGR before it, DSD also unjustifiably presumes that typical genitalia are necessary for cisgendered development. However, unlike OGR, it appeals to the empirically inadequate, theoretically suspect, and biologically determinist model of gender development known as brain‐organization theory. Given this, I conclude that the treatment of intersex people under DSD continues to be driven by problematically heterosexist and transphobic assumptions regarding the value and normalcy of cisgendered life, while practically and discursively constituting it as such.

Earlier evidence predominantly supports that women are more ethical than men. With the replication of such a hypothesis for testing, this study further examined whether feminine gender roles are a better predictor of ethical attitudes, ethical behaviors, and corporate responsibility values than the biological sex. Four hundred ten management students from two technical institutes in eastern India participated in this study. Along with the socio-demographic variables in the questionnaire, inventories were used to assess gender roles, ethical attitudes, ethical behaviors, and (...) corporate responsibility values. The inventories had acceptable reliability and validity. The results suggested that when the confounding effects of age, caste, and rural/urban origin are controlled, women manifest higher corporate responsibility values than men, but they embody similar ethical attitudes and ethical behaviors as men. Furthermore, the feminine roles of the participants were found to be more consistent, potent, and direct predictors of ethical attitudes, ethical behaviors, and corporate responsibility values than the biological sex. Hence, individuals with feminine roles may be better suited for ethical responsibilities. (shrink)

Darwin, Sex and Statusargues that a human sociobiology that mistakes evolutionary theory for theories of psychology and culture is wrong, as are psychologies that could never have evolved or social sciences that posit impossible psychologies.

Recurring themes include: the importance of sexual selection in human evolution; our species' preoccupation with self-esteem and relative standing; the individual as an active strategist, regularly revising culturally provided information; (...) and awareness as an impressionmanagement device.

The design argument for the existence of God took a probabilistic turn in the 17 th and 18 th centuries. Earlier versions, such as Thomas Aquinas' 5 th way, usually embraced the premise that goal-directed systems (things that "act for an end" or have a function) must have been created by an intelligent designer. This idea – which we might express by the slogan "no design without a designer" – survived into the 17 th and 18 th centuries, 1 and (...) it is with us still in the writings of many creationists. The new version of the argument, inspired by the emerging mathematical theory of probability, removed the premise of necessity. It begins with the thought that goal-directed systems might have arisen by intelligent design or by chance; the problem is to discern which hypothesis is more plausible. With the epistemic concept of plausibility characterized in terms of the mathematical concept of probability, the design argument was given a new direction. The new probabilistic perspective did not extinguish the older idea of "no design without a designer." The two conflicting approaches coexisted, often with less than perfect clarity about their fundamental difference. At the same time, the details of how the probabilistic perspective ought to be articulated were slow in emerging. These characteristics of uneven development are exemplified in a debate that took place in the 18 th century among three probabilists – John Arbuthnot, Nicholas Bernoulli, and Abraham DeMoivre – on the proper explanation of human sex ratio. Arbuthnot proposed a probabilistic version of the design argument, claiming that it is intelligent design, not chance, that provides the better explanation of why slightly more boys than girls are born each year. Bernoulli rejected Arbuthnot's argument. DeMoivre defended Arbuthnot against Bernoulli's criticisms. The problem of explaining sex ratio, both in human populations and in the rest of nature, experienced another transformation after 1859 --it became a problem for the theory of evolution by natural selection. Darwin (1871) addressed the question in the first edition of The Descent of Man but withdrew his suggestion in the second (Darwin 1874). Carl Düsing (1884) provided a mathematical model that moved beyond the explanation Darwin offered. Fisher (1930) added the new idea of parental expenditure. Williams (1966) argued that the sex ratios found in nature provide the opportunity to test hypotheses of group selection against hypotheses of individual selection. Hamilton (1967) constructed a model that generalizes Fisher's approach and represents the effects of both group and individual selection. The theory of natural selection gradually developed the ability to predict sex ratios, not just explain them post hoc. (shrink)

Our social role/biosocial theory provides a more adequate account of aggression sex differences than does Archer's sexual selection theory. In our theory, these sex differences arise flexibly from sociocultural and ecological forces in interaction with humans' biology, as defined by female and male physical attributes and reproductive activities. Our comments elaborate our theory's explanations for the varied phenomena that Archer presents.

In the early twentieth century, Tatsuo Aida in Japan, Øjvind Winge in Denmark, Richard Goldschmidt in Germany, and Calvin Bridges in the United States all developed different experimental systems to study the genetics of sex reversal.

The evidence favoring sex differences in pain seems compelling (berkley). This commentary considers the role of such factors as anxiety, somatosensory amplification, and coping style in accounting for the differential response to pain in the laboratory and clinic, and emphasizes the need to base evaluation and treatment upon individual reports rather than gender-based stereotypes.

Biological sex should be “acknowledged” and “accepted”—but which responses to gender dysphoria might this preclude? Trans-identified people may factually acknowledge their biological sex and regard transition as purely palliative. While generally some level of self-deception and even a high level of nonlying deception of others are sometimes justified, biological sex is important, and there is a nontrivial onus against even palliative, nonsexually motivated cross-dressing. The onus is higher against co-opting the body, even in a minor and/or reversible way, to make (...) a false communication concerning one’s sex. Hardest to defend is the destruction of sexual–reproductive functions and causally downstream functions such as lactation: due to the transcendent nature of sexual–reproductive functions, an appeal to the “principle of totality” here is misplaced. This is not to say that social, and milder medical, transition is absolutely excluded even for severe unmanageable dysphoria, nor that subsequent to any transition, detransition is necessarily required.
