  1. Hormone research as an exemplar of underdetermination.P. D. Magnus - 2005 - Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences 36 (3):559-567.
    Debates about the underdetermination of theory by data often turn on specific examples. Cases invoked often enough become familiar, even well worn. Since Helen Longino’s discussion of the case, the connection between prenatal hormone levels and gender-linked childhood behaviour has become one of these stock examples. However, as I argue here, the case is not genuinely underdetermined. We can easily imagine a possible experiment to decide the question. The fact that we would not perform this experiment is a moral, rather (...)

  2. Hormone replacement therapy: informed consent without assessment?Toni C. Saad, Bruce Philip Blackshaw & Daniel Rodger - 2019 - Journal of Medical Ethics 45 (12):1-2.
    Florence Ashley has argued that requiring patients with gender dysphoria to undergo an assessment and referral from a mental health professional before undergoing hormone replacement therapy (HRT) is unethical and may represent an unconscious hostility towards transgender people. We respond, first, by showing that Ashley has conflated the self-reporting of symptoms with self-diagnosis, and that this is not consistent with the standard model of informed consent to medical treatment. Second, we note that the model of informed consent involved in cosmetic (...)

  3. Gender Affirming Hormone Treatment for Trans Adolescents: A Four Principles Analysis.Hane Htut Maung - 2024 - Journal of Bioethical Inquiry (2):345-363.
    Gender affirming hormone treatment is an important part of the care of trans adolescents which enables them to develop the secondary sexual characteristics congruent with their identified genders. There is an increasing amount of empirical evidence showing the benefits of gender affirming hormone treatment for psychological health and social well-being in this population. However, in several countries, access to gender affirming hormone treatment for trans adolescents has recently been severely restricted. While much of the opposition to gender affirming hormone treatment (...)

  4. On Treating Athletes with Banned Substances: The Relationship Between Mild Traumatic Brain Injury, Hypopituitarism, and Hormone Replacement Therapy.Sarah Malanowski & Nicholas Baima - 2014 - Neuroethics 8 (1):27-38.
    Until recently, the problem of traumatic brain injury in sports and the problem of performance enhancement via hormone replacement have not been seen as related issues. However, recent evidence suggests that these two problems may actually interact in complex and previously underappreciated ways. A body of recent research has shown that traumatic brain injuries, at all ranges of severity, have a negative effect upon pituitary function, which results in diminished levels of several endogenous hormones, such as growth hormone and (...)

    Florence Ashley has responded to our response to ‘Gatekeeping hormone replacement therapy for transgender patients is dehumanising.’ Ashley criticises some of our objections to their view that patients seeking hormone replacement therapy (HRT) for gender dysphoria should not have to undergo a prior psychological assessment. Here we clarify our objections, most importantly that concerning the parity between cosmetic surgery and the sort of intervention Ashley has in mind. Firstly, we show Ashley’s criticism of our comparison is insubstantial. We then examine (...)

    The aim of this paper is to call the attention, especially that of feminists, to the current progress in biology. It appears gender studies still confine themselves to outdated ideas of sex chromosomes like XX, XY (§10). However, science has been making progress. It no longer sticks to such matters as XX, XY. Its interest is now in Sry, a kind of gene (§11), and MIS, a kind of sex hormone (§14). Abnormalities of sex chromosomes are no longer evidence to (...)

  13. Cyclic Cushing syndrome: definitions and treatment implications.Dennis Vélez - 2007 - Neurosurgical Focus 23 (3):E4, 1-3.
    Endogenous Cushing syndrome (CS) results from hypercortisolemia caused by excess adrenocorticotropic hormone production in a pituitary adenoma or ectopic tumor, or by an adrenal tumor that directly produces excess cortisol. The diagnosis can usually be ascertained with a reasonable degree of certainty based on clinical and laboratory findings of hypercortisolism. There are patients, however, in whom the production of excess cortisol exhibits a cyclic or intermittent pattern, and, as a result, the clinical symptoms may be quite complex and varied. In (...)

  15. Glycemia Regulation: From Feedback Loops to Organizational Closure.Leonardo Bich, Matteo Mossio & Ana M. Soto - 2020 - Frontiers in Physiology 11.
    Endocrinologists apply the idea of feedback loops to explain how hormones regulate certain bodily functions such as glucose metabolism. In particular, feedback loops focus on the maintenance of the plasma concentrations of glucose within a narrow range. Here, we put forward a different, organicist perspective on the endocrine regulation of glycaemia, by relying on the pivotal concept of closure of constraints. From this perspective, biological systems are understood as organized ones, which means that they are constituted of a set (...)

    The study of remembering is both compelling and challenging, in part, because of the multiplicity and the complexity of influences on memory. Whatever their interests, memory researchers are always aware of the many different factors that can drive the processes they care about. A search for the phrase ‘influences on memory’ confirms this daunting and exhilarating array of influences, of many different kinds, operating at many different timescales, and presumably often interacting in ways that we can’t yet imagine, let alone (...)

    In various documents the view emerges that contemporary biotechnosciences are currently experiencing a scientific revolution: a massive increase of pace, scale and scope. A significant part of the research endeavours involved in this scientific upheaval is devoted to understanding and, if possible, ameliorating humankind: from our genomes up to our bodies and brains. New developments in contemporary technosciences, such as synthetic biology and other genomics and “post-genomics” fields, tend to blur the distinctions between prevention, therapy and enhancement.

    The present study examined the endogenous release of luteinizing hormone-releasing hormone (LHRH) from superfused hypothalamic slices derived from Korean native cattie (KNC). In addition, the in vitro secretory pattern of LHRH release in '(NC was compared with that in imported cattle such as Holstein cow. The median eminences (ME) of hypothalamic tissues were dissected out, sliced, and quickly placed in an ice-cold superfusion chamber. Superfusion chambers containing ME slices were maintained in a constant temperature water-bath at 37∘C. Effluents were collected (...)

    Turing’s much debated test has turned 70 and is still fairly controversial. His 1950 paper is seen as a complex and multilayered text, and key questions about it remain largely unanswered. Why did Turing select learning from experience as the best approach to achieve machine intelligence? Why did he spend several years working with chess playing as a task to illustrate and test for machine intelligence only to trade it out for conversational question-answering in 1950? Why did Turing refer to (...)

    This essay develops a concept of curiotization, through which people are reduced to a curio for the fascination of others. I argue that trans people as they have appeared in media, philosophy, and narratives of history are curiotized as forever fascinating, new, titillating, and controversial. In contrast to the narrative of momentous trans progress in the mid-2010s, I point out that frameworks such as the "Transgender Tipping Point" worked to position its "trans moment" as unprecedented and always on the threshold (...)

    In the voluminous literature on the subject of bovine growth hormone (bGH) we have yet to find an attempt to frame the issue in specifically moral terms or to address systematically its ethical implications. I argue that there are two moral objections to the technology: its treatment of animals, and its dislocating effects on farmers. There are agricultural biotechnologies that deserve funding and support. bGH is not one of them.

  25. Coherent Causal Control: A New Distinction within Causation.Marcel Weber - 2022 - European Journal for Philosophy of Science 12 (4):69.
    The recent literature on causality has seen the introduction of several distinctions within causality, which are thought to be important for understanding the widespread scientific practice of focusing causal explanations on a subset of the factors that are causally relevant for a phenomenon. Concepts used to draw such distinctions include, among others, stability, specificity, proportionality, or actual-difference making. In this contribution, I propose a new distinction that picks out an explanatorily salient class of causes in biological systems. Some select causes (...)

    This contribution demonstrates that the development and growth of plants depends on the success of complex communication processes. These communication processes are primarily sign-mediated interactions and are not simply an mechanical exchange of ‘information’, as that term has come to be understood (or misunderstood) in science. Rather, such interactions as I will be describing here involve the active coordination and organisation of a great variety of different behavioural patterns — all of which must be mediated by signs. Thus proposed, a (...)

  30. Genes, Affect, and Reason: Why Autonomous Robot Intelligence Will Be Nothing Like Human Intelligence.Henry Moss - 2016 - Techné: Research in Philosophy and Technology 20 (1):1-15.
    Abstract: Many believe that, in addition to cognitive capacities, autonomous robots need something similar to affect. As in humans, affect, including specific emotions, would filter robot experience based on a set of goals, values, and interests. This narrows behavioral options and avoids combinatorial explosion or regress problems that challenge purely cognitive assessments in a continuously changing experiential field. Adding human-like affect to robots is not straightforward, however. Affect in organisms is an aspect of evolved biological systems, from the taxes of (...)

    [NOTE: I now disavow this essay, which was too accommodating of trans ideology.] Surprisingly, it follows from commonplaces about sex and gender that there is a widely-practiced variety of transgenderism achievable through sex/gender “exaggerating.” Recognizing exaggeration as trans---or at least its moral equivalent---has several important consequences. One is that, since most traditional cultures endorse exaggeration, trans lifestyles have often been mainstream. But more importantly, recognizing that gender exaggeration is trans (or its moral equivalent) reveals a number of sex- and gender-discriminatory (...)

    Spermatogenesis is the process of producing sperm in the testicles. It occurs in several stages, starting with the primordial germ cells, which differentiate into spermatogonia. Spermatogonia undergo successive mitoses to form primary spermatocytes, which, in turn, undergo meiosis, resulting in secondary spermatocytes. Secondary spermatocytes later transform into spermatids, which are immature sperm. Spermatids undergo maturation and differentiation to become mature sperm, ready for fertilization. This process is highly regulated by hormones and is essential for male fertility and reproduction. Spermatogenesis (...)

  42. Breastfeeding Mothers’ Experiences: The Ghost in the Machine.Paul Regan & Elaine Ball - 2013 - Qualitative Health Research 23 (5):679-688.
    We critically review qualitative research studies conducted from 2000 to 2012 exploring Western mothers’ breastfeeding experiences. We used the search criteria “breastfeeding,” “qualitative,” and “experiences” to retrieve 74 qualitative research studies, which were reduced to 28 when the terms “existential’’ and “research’’ were applied. We found that the impact of technology and the pervasive worldwide marketing of infant formula devalued breastfeeding mothers’ narratives in a number of ways. Women’s bodies were viewed as machine-like objects and the breast was seen as (...)

  47. Estabelecimento da Gestação nos Animais.Emanuel Isaque Cordeiro da Silva - manuscript
    OBJETIVO A gestação nos mamíferos domésticos é um processo fisiológico que implica mudanças físicas, metabólicas e hormonais na fêmea, que culminam com o nascimento de um novo indivíduo. Desta forma, a compreensão de tais mudanças e como estas favorecem um ambiente ideal de desenvolvimento embrionário inicial, até a placentação e a fisiologia envolvidas durante esses processos é fundamental na tomada de decisões quanto à saúde reprodutiva da fêmea, na seleção de futuras matrizes e até mesmo para a saúde fetal e (...)
