The nervous system and the endocrine system interact to integrate behavior and physiolo­gy. Hormones play an important role in this interaction, particularly steroid hormones. Other molecules, notably oxytocin, can serve both as hormones in the soma and neuro­modulators in the central nervous system. Understanding the influence of the endocrine system on human behavior, both individual and social, has been a primary focus of behav­ioral endocrinology for many decades, though technical and methodological challenges have been formidable. The recent enthusiasm for (...) enzyme-linked immunoassay kits for measuring steroid hormones in saliva has been found to be largely unsound, for example. Despite these difficulties, advances in many areas have been made and new areas, such as the endocrinology of paternal behavior and the role of oxytocin in social interactions, have emerged. Reproductive ecology provides a theoretical framework for integrating the di­verse content of human behavioral ecology. (shrink)

SummaryThe Gainj of highland Papua New Guinea do not use contraception but have a total fertility rate of only 4·3 live births per woman, one of the lowest ever recorded in a natural fertility setting. From an analysis of cross-sectional demographic and endocrinological data, the causes of low reproductive output have been identified in women of this population as: late menarche and marriage, a long interval between marriage and first birth, a high probability of widowhood at later reproductive ages, low (...) effective fecundability and prolonged lactational amenorrhoea. These are combined with near-universal marriage, a low prevalence of primary sterility and a pattern of onset of secondary sterility similar to that found in other populations. Of all the factors limiting fertility, by far the most important are those involved in birth spacing, especially lactational amenorrhoea. (shrink)

I hypothesize here that the ability of probiotics to synthesize neuroactive compounds provides a unifying microbial endocrinology‐based mechanism to explain the hitherto incompletely understood action of commensal microbiota that affect the host's gastrointestinal and psychological health. Once ingested, probiotics enter an interactive environment encompassing microbiological, immunological, and neurophysiological components. By utilizing a trans‐disciplinary framework known as microbial endocrinology, mechanisms that would otherwise not be considered become apparent since any candidate would need to be shared among all three components. (...) The range of neurochemicals produced by probiotics includes neurochemicals for which receptor‐based targets on immune and neuronal elements (intestinal and extra‐intestinal) have been well characterized. Production of neurochemicals by probiotics therefore allows for their consideration as delivery vehicles for neuroactive compounds. This unifying microbial endocrinology‐based hypothesis, which may facilitate the selection and design of probiotics for clinical use, also highlights the largely unrecognized role of neuroscience in understanding how microbes may influence health.Editor's suggested further reading in BioEssays Harvesting the biological potential of the human gut microbiome Abstract.

Early scientific investigation of the reproductive process was neither a cause nor a direct result of changing social attitudes toward sex. It was instead part of the continuing search, initiated in the 1890s, to discover internal secretions that might be isolated and prove useful in therapy. Laboratory scientists, nonetheless, were among the many groups altering understanding of human sexual physiology in the first quarter of this century. The new data they generated regarding the dependence of human sexuality and fertility on (...) chemical substances elaborated by the ovaries and testes became part of the evidence which hastened that quite tortuous transformation called the sexual revolution.Increasingly, as social reformers demanded more information about human reproduction, scientists were asked to provide it, and scientific concerns were shaped in the process. In the 1920s, especially in the United States, studies of the physiology of reproduction began to receive financial backing from social reformers. This was because for many, contraception had become a fact of life. Expression rather than repression of sexuality was accepted as being necessary to the stability of the fundamental social unit, the family. Theoretical and practical incentives for continued study of the reproductive process could thus be joined in common effort. This convergence of goals occurred just as the gonadal hormones were being isolated. The 1920s, therefore, mark an important juncture in the congruence of interests represented by theoretical science on the one hand and expressed social needs on the other.As a result of this convergence of interests and goals, physiologists gained a new realm of influence, claiming authoritative knowledge over a subject which once had been allocated to the priest and then, by the mid-nineteenth century, transferred to the physician. Since that formative period other research scientists, such as Alfred Kinsey and, more recently, William Masters and Virginia Johnson, have explored that niche and applied the scientific method to study of behavioral and physiological aspects of the human sexual response. They have been beset by many of the same tactical issues that confronted the earliest investigators of reproductive physiology. The definition, specification, and measurement of phenomena relating to sexual and reproductive activity have been as inherently difficult as they have been taboo.79Traditional resistance to scientific study of the reproductive process was overcome in the early twentieth century by the expectation that this particular line of inquiry would lead to understanding and therefore medical control of the complex of disorders—physiological, psychological, and social — associated with the generative glands. Early investigators, particularly in Britain, did not wish to be social reformers. Especially in the 1910s such a stance would have threatened their credibility in a field determined to establish itself as a theoretical science. Once scientific progress was assured, as it was from about 1920, new problems opened for investigation and began to be motivated by social needs as well as by the concerns of a rapidly developing science. Especially in the United States new resources encouraged this work, allowing development of the specialized focus on gonadal hormones represented by the emerging field of reproductive endocrinology.

A political discourse of peace marked the distribution and use of radioisotopes in biomedical research and in medical diagnosis and therapy in the post-World War II period.

This article follows the importation of radioisotopes by two Spanish research groups, one in experimental (...) endocrinology and one in molecular biology. For both groups foreign funds were instrumental in the early establishment of their laboratories.

During the 1890s, animal development became associated with glandular activity, with profound implications for pediatric nosology and treatment. The significance of this endocrinological turn of developmental physiology and pathophysiology in part hinges on an often-overlooked continuity with ubiquitous early modern medical thought concerning semen as a recrementitious (reabsorbed) nutrient or stimulant. Mid-19th-century interests in adult sexual physiology were increasingly nerve-centered and antihumoral. Scattered empirical, particularly veterinarian, interests in gonadal developmental functions failed to moderate these explanatory trends. While Brown-Séquard’s rejuvenation experiments (...) still offered no clear starting point for a developmental endocrinology, in 1892 Gaston Variot and Paul Bezançon more explicitly deduced a testicular developmental endocrinological function from various observations on testicular ectopy and a local form of animal “demi-castration.” Ensuing interest in the thyroid, the thymus and in the testicles led to various working conceptions of their respective and putatively reciprocal developmental properties, including the idea of a thyroid–testis axis. From 1896, the pubertal affliction of chlorosis became the subject of multiple opotherapeutic approaches, providing an experimental basis for theories of ovarian internal secretion. Polyglandular therapy, piloted for divergent developmental conditions, remained routine until the 1930s despite the biological inefficacy of many endocrine products. (shrink)

In 1920, Eugen Steinach and Paul Kammerer reported experiments showing that exposure to high temperatures altered the structure of the gonad and produced hyper-sexuality in "heat rats," presumably as a result of the increased production of sex hormones. Using Steinach's evidence that the gonad is a double gland with distinct sexual and generative functions, they used their findings to explain "racial" differences in the sexuality of indigenous tropical peoples and Europeans. The authors also reported that heat induced anatomical changes in (...) the interstitial cells of the gonad were inherited by the heat rats' descendants. Kammerer used this finding to link endocrinology to his long-standing interest in the inheritance of acquired characteristics. The heat rats supported his hypothesis that the interstitial cells of the double gland were the mechanism of somatic induction in the inheritance of acquired characteristics. The Steinach-Kammerer collaboration, Kammerer's use of Steinach's "puberty gland" to explain somatic induction, and his endocrine analysis of symbiosis reveal Paul Kammerer's late career attempt to integrate endocrinology and genetics with the political ideals of Austrian socialism. With them he developed a bioethics that challenged the growing reliance on race in eugenics and instead promoted cooperation over competition in evolution. I relate his attempt to the controversies surrounding the interstitial cells, to the status of extra-nuclear theories of heredity, and to Kammerer's commitment to Austromarxist social reforms during the interwar period.

This essay argues that the reigning medical and scientific understanding of the endocrine system, which insists on its fundamental biological plasticity, was historically constructed through a dual child–animal metaphor. The work accomplished by such organic metaphors, as Donna Haraway terms them, returns us to the endocrine laboratories and clinics in which they were built in Europe and the United States in the first half of the twentieth century. The child and animal metaphors implanted the concept of plasticity into the human (...) body to the effect of bringing sexed and gendered life under the jurisdiction of science and medicine, where it could not only be normalized in a sense long appreciated by transgender studies but also cultivated towards the ostensible “improvement” and “perfection” of the human. This is also, then, a history of the eugenic heritage of modern endocrinology, which has been largely ignored in recent discussions of plasticity and the body’s materiality. To interrogate the role of foundational organic metaphors in endocrinology is to open up plasticity not only to its historical context but also to radical contestation, making the contemporary assumptions of transgender medicine untimely, particularly the medicalization of the transgender child.

This article deals with the relationship between the creator of psychoanalysis, Sigmund Freud, and the Latvian-born Chilean professor of physiology – and endocrinologist and anthropologist – Alejandro (or Alexander) Lipschütz. Up till now, the historiography of psychoanalysis in Chile has ignored the existence of this relationship, that is to say, the fact that there exists an interesting exchange of correspondence as well as references to Lipschütz in some important works published by Freud and in Freud’s correspondence with the Hungarian psychoanalyst (...) Sándor Ferenczi. There are also references to works on psychoanalysis carried out by Lipschütz in Chile. The Freud–Lipschütz relationship allows us to examine two interesting topics in contemporary historiographical approaches to psychoanalysis. First, it permits us to reflect on the connections that Freud and Ferenczi sought to establish between psychoanalysis and biology (endocrinology in particular) as a strategy to address criticism of the scientific foundations of psychoanalysis and, therefore, to help legitimize psychoanalysis in the field of science. Second, the relationship between Freud, working in a culturally influential city such as Vienna, and Lipschütz, working in a ‘peripheral’ country such as Chile, paves the way to reflect on the consequences of a history of psychoanalysis written from the perspective of the ‘margins’. This is a history that focuses not on regions where early industrialization and modernization processes, along with an important academic and scientific tradition, help explain the interest in and reception of psychoanalysis, but on regions where different sets of conditions have to be examined to explain appropriation and dissemination processes.

This paper compares and contrasts three groups that conducted biological research at Yale University during overlapping periods between 1910 and 1970. Yale University proved important as a site for this research. The leaders of these groups were Ross Granville Harrison, Grace E. Pickford, and G. Evelyn Hutchinson, and their members included both graduate students and more experienced scientists. All produced innovative research, including the opening of new subfields in embryology, endocrinology and ecology respectively, over a long period of time. (...) Harrison's is shown to have been a classic research school; Pickford's and Hutchinson's were not. Pickford's group was successful in spite of her lack of departmental or institutional position or power. Hutchinson and his graduate and post-graduate students were extremely productive but in diverse areas of ecology. His group did not have one focused area of research or use one set of research tools. The paper concludes that new models for research groups are needed, especially for those, like Hutchinson's, that included much field research. (shrink)

Recent studies in social endocrinology have explored the effects of social relationships on female reproductive steroid hormones—estradiol and progesterone—investigating whether they are suppressed in partnered and parous women. Results have been mixed for these hormones although evidence is more consistent that partnered women and women with young children have lower levels of testosterone. These studies were sequential to earlier research on men, based on Wingfield’s Challenge Hypothesis, which showed that men in committed relationships, or with young children, have lower (...) levels of testosterone than unpartnered men or men with older or no children. The study described here explored associations between estradiol and progesterone with partnership and parity among women from two different ethnicities: South Asian and white British. We hypothesized that both steroid hormones would be lower among partnered and/or parous women with children ≤3 years old, regardless of ethnicity. In this study we analyzed data from 320 Bangladeshi and British women of European origin aged 18 to 50 who participated in two previous studies of reproductive ecology and health. Levels of estradiol and progesterone were assayed using saliva and/or serum samples and the body mass index calculated from anthropometric data. Questionnaires provided other covariates. Multiple linear regressions were used to analyze the data. The hypotheses were not supported. We argue here that, unlike links between testosterone and male social relationships, theoretical foundations for such relationships with female reproductive steroid hormones are lacking, especially given the primary role of these steroids in regulating female reproductive function. Further longitudinal studies are needed to explore the bases of independent relationships between social factors and female reproductive steroid hormones. (shrink)

Obesity is the focus of multiple lines of inquiry that have -- together and separately -- produced many deep insights into the physiology of weight gain and maintenance. We examine three such streams of research and show how they are oriented to obesity intervention through multilevel integrated approaches. The first research programme is concerned with the genetics and biochemistry of fat production, and it links metabolism, physiology, endocrinology and neurochemistry. The second account of obesity is developmental and draws together (...) epigenetic and environmental explanations that can be embedded in an evolutionary framework. The third line of research focuses on the role of gut microbes in the production of obesity, and how microbial activities interact with host genetics, development and metabolism. These interwoven explanatory strategies are driven by an orientation to intervention, both for experimental and therapeutic outcomes. We connect the integrative and intervention-oriented aspects of obesity research through a discussion of translation, broadening the concept to capture the dynamic, iterative processes of scientific practice and therapy development. This system-oriented analysis of obesity research expands the philosophical scrutiny of contemporary developments in the biosciences and biomedicine, and has the potential to enrich philosophy of science and medicine.

Precision medicine and molecular systems medicine (MSM) are highly utilized and successful approaches to improve understanding, diagnosis, and treatment of many diseases from bench-to-bedside. Especially in the COVID-19 pandemic, molecular techniques and biotechnological innovation have proven to be of utmost importance for rapid developments in disease diagnostics and treatment, including DNA and RNA sequencing technology, treatment with drugs and natural products and vaccine development. The COVID-19 crisis, however, has also demonstrated the need for systemic thinking and transdisciplinarity and the limits (...) of MSM: the neglect of the bio-psycho-social systemic nature of humans and their context as the object of individual therapeutic and population-oriented interventions. COVID-19 illustrates how a medical problem requires a transdisciplinary approach in epidemiology, pathology, internal medicine, public health, environmental medicine, and socio-economic modeling. Regarding the need for conceptual integration of these different kinds of knowledge we suggest the application of general system theory (GST). This approach endorses an organism-centered view on health and disease, which according to Ludwig von Bertalanffy who was the founder of GST, we call Organismal Systems Medicine (OSM). We argue that systems science offers wider applications in the field of pathology and can contribute to an integrative systems medicine by (i) integration of evidence across functional and structural differentially scaled subsystems, (ii) conceptualization of complex multilevel systems, and (iii) suggesting mechanisms and non-linear relationships underlying the observed phenomena. We underline these points with a proposal on multi-level systems pathology including neurophysiology, endocrinology, immune system, genetics, and general metabolism. An integration of these areas is necessary to understand excess mortality rates and polypharmacological treatments. In the pandemic era this multi-level systems pathology is most important to assess potential vaccines, their effectiveness, short-, and long-time adverse effects. We further argue that these conceptual frameworks are not only valid in the COVID-19 era but also important to be integrated in a medicinal curriculum. (shrink)

This essay explores how hormone treatments were used to optimize and normalize individuals under Italian Fascism. It does so by taking the activities of the Biotypological Orthogenetic Institute − an Italian eugenics and endocrinological centre founded by Nicola Pende in 1926 − as the prime example of a version of eugenics, biotypology, which was based on hormone therapies. This essay first demonstrates that Italian Fascist biopolitics was not only concerned with increasing the size of the Italian population, but also with (...) improving its quality. It suggests that under the Italian Fascist regime hormone therapies became eugenic tools of intervention to improve the Italian race. Second, while Pende's institute purportedly enhanced men and women, its activities show the extent to which the ‘techniques of normalization’ pursued by the Fascist regime were both systematic and invasive.

Few areas of scientific investigation have spawned more alternative approaches than animal behavior: comparative psychology, ethology, behavioral ecology, sociobiology, behavioral endocrinology, behavioral neuroscience, neuroethology, behavioral genetics, cognitive ethology, developmental psychobiology---the list goes on. Add in the behavioral sciences focused on the human animal, and you can continue the list with ethnography, biological anthropology, political science, sociology, psychology (cognitive, social, developmental, evolutionary, etc.), and even that dismal science, economics. Clearly, no reasonable-length chapter can do justice to such a varied collection. (...) We have opted therefore to focus on three of these subdisciplines and to provide a somewhat historical tour of them, mentioning along the way the philosophical points that are of particular interest to us, but allowing the development of these points to be limited only by the imaginations of our readers. For readers seeking a more-traditional historical survey, see Dewsbury (1984a, b) and Burghardt (1985a). Our chosen brief is to write about comparative psychology, ethology, and cognitive ethology, although other approaches, especially neuroscience, will be mentioned where appropriate. These sciences are philosophically significant because they are enmeshed in ancient philosophical questions about the nature of mind and purposeful action and about the differences between humans and other animals. These sciences are also clustered because of their attention to mechanistic explanations of individual animal behavior as opposed to attempting to capture regularities at a population level, such as the game-theoretic strategic models popular among behavioral ecologists.

Phylogenetically controlled studies across multiple species correct for taxonomic confounds in physiological performance traits. Therefore, they are preferred over comparisons of two or few closely‐related species. Funding bodies, referees and journal editors nowadays often even reject to consider detailed comparisons of two or few closely related species. Here, we plea for a less dogmatic stance on such comparisons, because phylogenetic studies come with their own limitations similar in magnitude as those of two‐species comparisons. Two‐species comparisons are particularly relevant and instructive (...) for understanding physiological pathways and de novo mutations in three contexts: in a purely mechanistic context, when differences in the regulation of a trait are the focus of investigation, when a physiological trait lacks a direct connection to fitness, and when physiological measures cannot easily be standardized among laboratories. In conclusion, phylogenetic comparative and two‐species studies have different strengths and weaknesses and combining these complementary approaches will help integrating biology. (shrink)

BackgroundIn gender-affirming medical care (GAMC), ethical challenges in decision-making are ubiquitous. These challenges are becoming more pressing due to exponentially increasing referrals, politico-legal contestation, and divergent normative views regarding decisional roles and models. Little is known, however, about what ethical challenges related to decision-making healthcare professionals (HCPs) themselves face in their daily work in GAMC and how these relate to, for example, the subjective nature of Gender Incongruence (GI), the multidisciplinary character of GAMC and the role HCPs play in assessing (...) GI and eligibility for interventions. Given the relevance and urgency of these questions, we conducted a qualitative study among HCPs providing GAMC to transgender adults in the Netherlands.MethodsIn this qualitative research, we conducted 11 semi-structured interviews between May 2020 and February 2021 with HCPs (six mental health professionals, two HCPs in endocrinology, two in plastic surgery, and one in nursing) working in two distinct GAMC settings. We purposively sampled for professional background and years of experience in GAMC. We analyzed our interview data using thematic analysis. As some respondents were more inclined to speak about what should or ought to be done to arrive at good or right decision-making, we identified both ethical challenges and norms. Furthermore, in our analysis, we differentiated between respondents’ explicit and implicit ethical challenges and norms and ascertained the specific context in which these challenges emerged.ResultsRespondents’ ethical challenges and norms centered on (1) dividing and defining decisional roles and bounds, (2) negotiating decision-making in a (multidisciplinary) team, and (3) navigating various decision-making temporalities. These themes arose in the context of uncertainties regarding (1) GAMC’s guidelines, evidence, and outcomes, as well as (2) the boundaries and assessment of GI.ConclusionsThis interview study provides detailed empirical insight into both the explicit and implicit ethical challenges that HCPs experience and their ethical norms regarding decision-making. It also describes how uncertainties and (implicit) normativities concerning GAMC and GI pre-structure the moral environment in which these challenges and norms manifest. We provide normative reflections and recommendations on handling these ethical challenges in a way that is sensitive to the context in which they arise. (shrink)

Sex is a fundamentally important biological variable. Recent years have seen significant progress in the integration of sex in many aspects of basic and clinical research, including analyses of sex differences in brain function. Significant advances in the technology available for studying the endocrine and nervous systems are now coupled with a more sophisticated awareness of the interconnections of these two communication systems of the body. A thorough understanding of the current knowledge, conceptual approaches, methodological capabilities, and challenges is a (...) prerequisite to continued progress in research and therapeutics in this interdisciplinary area. Sex Differences in the Brain provides scientists with the basic tools for investigating sex differences in brain and behavior and insight into areas where important progress in understanding physiologically relevant sex differences has already been made. This book was edited and co-authored by members of the Isis Fund Network on Sex, Gender, Drugs and the Brain, sponsored by the Society for Womens Health Research. The book is arranged in three parts. The first part of the book introduces the study of sex differences in the brain, with an overview of how the brain, stress systems, and pharmacogenetics differ in males and females and how this information is important for the study of behavior and neurobiology of both genders. The second part presents examples of sex differences in neurobiology and behavior from both basic and clinical research perspectives, covering both humans and nonhuman animals. The final part discusses sex differences in the neurobiology of disease and neurological disorders. For interested individuals as well as those who are considering conducting research at the intersections of endocrinology, neuroscience, and other areas of biomedicine, the study of sex differences offers exciting and challenging questions and perspectives. This book is intended as a guide and resource for clinicians, scientists, and students. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Intersection of Medicine and ReligionJohn C. DormoisThe practice of medicine offers a host of rewards to the practitioner. Besides the obvious intellectual satisfaction of solving a difficult diagnostic problem or the ability to make a comfortable living, I have found the greatest personal sense of moral gratification when helping [End Page 196] families negotiate the most challenging event in life: making decisions at end of life. Whether the (...) condition was a ruptured intracranial aneurysm with brain death or a patient with far advanced cancer struggling with the choice between experimental chemotherapy or choosing comfort therapy at home surrounded by family for the remaining days of life, the moral courage required to provide the best guidance was considerable. In my early years of practice I didn’t call my actions in these situations “courageous” nor were there moral “guidelines” providing a blueprint. I knew I responded with empathy and compassion and that this ability had a lot to do with being raised in a religious or spiritual home. At the same time, I suspected that some of the lack of empathy and compassion I witnessed in some of my colleagues was related to the very training programs of physicians. This essay traces the origin of my moral and ethical concerns about medical education and my intention to reinvigorate the spiritual or existential voice in medicine.An early life experience had a great deal to do with shaping my moral development. At age seven my family traveled through the West Indies. My father’s amateur radio hobby meant that at every stop we would be greeted by one of his radio contacts. One stop in particular was life changing.Port au Prince, Haiti was an unknown place to this seven year–old, but to say it was a culture shock to a boy from Kansas would be an understatement of epic proportions. It was during this visit that I experienced true poverty in its most blatant form. In downtown Port au Prince I saw limbless beggars and the deformed from polio and malnutrition. But it was the sight of the garbage dump near the center of town that changed my world forever. There, among piles of detritus, I saw children and families making their home in the dump. They had hollowed out a sort of cavern in the piles of trash that served as a place of refuge from both the rain and the sun.This experience in many ways has served as a framework and background for my life. Although seen through the eyes of a seven year–old, the picture can only be adequately understood within the context of being raised by religiously faithful parents, parents free of hypocrisy whose lives personified the best in Christian virtues and practices. These early experiences planted the seeds that would only fully blossom some 60 years later.Medical school was a demanding but exhilarating experience. Each day was a day of discovery … anatomy, physiology, pathology … all subjects opening up a whole new world to explore. Internal medicine suited me best since it was the specialty that most closely integrated all the basic sciences necessary to arrive at a diagnosis. I loved the elegance of endocrinology in particular where a given hormone mediator could cause widely different effects if present in excess or completely absent. But I was in the end drawn to cardiology since it combined complex physiology with my avocation, the love of running.There was, however, a disturbing aspect of medicine education that I observed affecting many of my classmates. Although I can vividly recall the enthusiasm that all of us shared as we donned our white coats for the first time and envisioned a future of caring for our patients, things gradually and insidiously changed over the next four years. The altruism and empathy that was so evident in the early years gradually lessened as graduation approached. I could not help being struck by this change and wondered at the time why that should happen. I had no insight then that what I had observed was a well recognized consequence of the medical school experience. I’m sure that the passage from professional training to practice in... (shrink)

What was it like to be a woman scientist battling the “old boy’s” network during the 1960s and 1970s? Neena Schwartz, a prominent neuroendocrinologist at Northwestern University, tells all. She became a successful scientist and administrator at a time when few women entered science and fewer succeeded in establishing independent laboratories. She describes her personal career struggles, and those of others in academia, as well as the events which lead to the formation of the Association of Women in Science, and (...) Women in Endocrinology, two national organizations, which have been successful in increasing the numbers of women scientists and their influence in their fields. The book intersperses this socio-political story with an account of Schwartz’s personal life as a lesbian and a description of her research on the role of hormones in regulating reproductive cycles. In a chapter titled “Don’t Ask, Don’t Tell,” she examines the “evidence” from a scientist’s point of view for the hormonal and genetic theories for homosexuality. Other chapters provide advice on mentoring young scientists and a discourse on why it matters to all of us to have more women doing and teaching science. She also describes the process of putting together an interdisciplinary Center on Reproductive Science at Northwestern, which brought together basic and clinical scientists in an internationally recognized program of research and practice.

Solly Zuckerman’s work has been largely dismissed or marginalized by both historians of primatology and primatologists. This paper, using archival and published materials, re-examines both his life and his research into primate sexuality and sociology in the 1920s, endocrinology in the 1930s, and the effects of bomb blast in the 1940s. Despite the many flaws in his work, which is now largely outdated, his career reveals a great deal about the audiences for primatological knowledge in pre-war and wartime Britain; (...) the interlocking circles of the scientific community that impinged on primatology; and competing ideas of what constituted a scientifically correct methodology for the observation of primate behaviour. Also noted is the gap between Zuckerman’s self-presentation as the scourge of anthropomorphism and the anthropomorphism of his remarks in private notebooks. Although his work well illustrates familiar themes of patriarchy, military and colonialism in the history of primatology, it also suggests another, underexplored dimension of that science: primatology as an example of cross-species social interaction.

My aim in this paper is to re-examine specialization in science. I argue that we need to acknowledge the role that conceptual changes can play in the creation of new specialties.

Specifically, I argue that conceptual developments played an important role in the creation of both (...) endocrinology and virology. (shrink)

As a gynecologic surgeon with a focus on infertility, I frequently hold complex discussions with patients, exploring with them the risks and benefits of surgical options. In the past, we physicians may have expected our patients to simply defer to our expertise and choose from the options we presented. In our contemporary era, however, patients frequently request options not favored by their physicians and even some they've found themselves online. In reproductive endocrinology and infertility, the range of options that (...) may be offered or that patients may themselves seek out is continuously widening. Physicians certainly seek to find the option that will result in the best outcome for their patients, but the information to guide us in achieving the best outcome can be vague or conflicting. Add to this the financial and emotional pressures bearing on patients seeking assisted reproduction. In this essay, I explore the extent to which clinicians in reproductive medicine should follow patient requests with which they disagree or instead try to persuade the patient to do something else or simply refuse outright to meet the request. And if persuasion is to be used, what would be legitimate methods? Clearly, coercion is unacceptable, but the line between persuasion and coercion can be elusive. At what point can or should clinicians resist such requests—and to what degree? (shrink)

Displacing the physiological model that had held sway in 19th-century medical thinking, early 20th-century medical scientists working on hormones promoted a new understanding of the body, psychological reactions, and the sexual instinct, arguing that each were fundamentally malleable. Hormones came to be understood as the chemical messengers that regulated an individual's growth and sexual development, and sexologists interested in this area focused primarily on children and adolescents. Hormone research also promoted a view of the body in which ‘hermaphroditism’, homosexuality, and (...) ‘sexual perversions’ such as masochism and sadism were attributed to anomalies in the internal secretions produced by the testes or the ovaries. This article focuses on Spanish, Italian, Argentinian, and Brazilian sexology shaped by endocrinological research in the interwar period. First, it shows the key role hormone treatments played in the historical development of sexology in Southern Europe and Latin America. Second, it looks at how sexologists employed hormone research to study human sexual development in the early stages of life, and how they set about ‘correcting’ what they viewed as ‘sexual anomalies’.

This appointment was different though; it came about as a result of request by a psychology professor who was conducting a follow–up study on individuals treated by the team of endocrinologists I saw as a child.The professor had reached out to me through my parents, since that was the only contact information available. It had been more than ten years since I had seen any of the doctors who treated me as a child. I was living in another state when I received the call from my mother informing me of the request for my participation in the study. I was really quite shocked; in all the years I was treated in early childhood and adolescence, no one had ever asked me how I felt about the treatment I received. I knew I had a medical condition, but no one ever explained to me why I needed so many appointments, and why I had to take medicine three times a day. No one told me why, when I was two or three years old, I had surgery that left me with memories of gauze and a catheter between my legs, or why medical residents still wanted to examine me, or why I had to be humiliated and ashamed, again and again. I was in my early 30’s by this time. Surely if my condition was so important that someone wanted to talk to me now, so many years later, the conversation would have already happened?!My parents dropped me off at the scheduled location for the interview. The professor introduced himself and his colleague. I didn’t recognize them, which meant they weren’t the doctors who had treated me. I remember feeling somewhat relieved, as I never liked the doctors who treated me as a child. I remembered my last appointment there, and feeling that I was escaping from captivity, that I was free to go on with my life.I wasn’t sure what to expect from this meeting. The professor told me that to date no one had completed any follow–up on the pediatric patients treated by the hospital’s endocrinology team to see how they were faring in life. He said he thought that was quite odd, so had decided to take on the project himself. He began by asking, “so, D_____, [I went by another name then] how are you doing at this point in your life?”I felt a sudden surge of rage, and, to my own surprise, I found myself responding angrily, “Why the hell do you care? It’s been over ten years and nobody, I mean nobody gives a rat’s ass as to how I’m doing and coping with the ramifications of the treatment I received from Dr. X.” Looking back, more than ten years after this meeting, I can see that I had been angry for a long time. I had been compliant and knew to play my role as a good girl. I had a good job, and I was married, but I knew I was far from happy.And so with that first question began what would be the long painful journey to discovering what had been hidden from me for over half my life, the source of my confusion and unparalleled frustration. What I had experienced throughout my childhood would permeate every aspect of my being and perception of myself for years to come. Every day I had to confront the effects of that experience just to live another day.The MiddleI was in shock and disbelief as I read and reread the letter my attorney presented to me from the very group of...

Understanding how traits are integrated at the organismal level remains a fundamental problem at the interface of developmental and evolutionary biology. Hormones, regulatory signaling molecules that coordinate multiple developmental and physiological processes, are major determinants underlying phenotypic integration. The probably best example for this is the lipid-like juvenile hormone (JH) in insects. Here we review the manifold effects of JH, the most versatile animal hormone, with an emphasis on the fruit fly Drosophila melanogaster, an organism amenable to both genetics and (...) endocrinology. JH affects a remarkable number of processes and traits in Drosophila development and life history, including metamorphosis, behavior, reproduction, diapause, stress resistance and aging. While many molecular details underlying JH signaling remain unknown, we argue that studying “hormonal pleiotropy” offers intriguing insights into phenotypic integration and the mechanisms underlying life history evolution. In particular, we illustrate the role of JH as a key mediator of life history trade-offs. BioEssays 27:999–1010, 2005. © 2005 Wiley Periodicals, Inc. (shrink)
