<p>In January 1932, the Sydney-based lifestyle magazine Health and Physical Culture published an article titled ‘The Menace of Effeminacy’. This article, written by Carl Hertzig, and read by magazine-subscribers across the Tasman, documented anxieties around the state of men and masculinity following the upheaval of the Great War. Touching on topics such as gender, psychology, eugenics, and sexuality this article and its concerns represent those that this thesis explores in order to understand what the ‘fear of effeminacy’ actually meant for New Zealanders during the interwar years (c.1918-1939). This thesis documents and analyses contemporary discussions of male sexuality and masculinity through a series of sources in order to establish the ways in which these concepts were understood in interwar New Zealand. Firstly, it examines some of the key pieces of legislation and reports that demonstrated official approaches, and ways of thinking, towards mental defectives, sexual offenders, and those with war neuroses. It then explores medical journals, and the dissertations of medical students; and finally, it analyses parts of popular print culture in Aotearoa/New Zealand, such as magazines and newspapers, in order to investigate and piece together the landscape in which said anxieties around effeminacy, masculinity, mental stability, and other deviations from the societally prescribed norm met. This thesis approaches these primary sources in such a way that acknowledges the evolutionary framework of understanding that was pervasive in medical circles during this era.  By thus examining the connections between constructions of the male body, homosexuality and effeminacy, late nineteenth to early twentieth century ideas around eugenics, and psychology and psychiatry, this work further uncovers the state of masculinity and male sexuality in New Zealand during the interwar period. This thesis argues that the ‘threat’ to masculinity perceived in a variety of venues was a mixture of anxieties around physical and mental wounds inflicted by the Great War; population concerns exacerbated by the exposure of the health-standards of troops, and worries of how to recover and reconstruct a virile society following four years of strife; concerns at the apparent loosening of sexual mores, and the changing manifestations of both masculinity and femininity; and ever increasing interest in the psychology of self, sexuality, and society. It adds to existing work on post-World War One masculinity by centring New Zealand discussions and understandings in a way that contributes to the broader literature on New Zealand twentieth-century masculinity, psychology and psychiatry, eugenics, and male sexuality.</p>

A high genetic load can negatively affect population viability and increase susceptibility to diseases and other environmental stressors. Prior microsatellite studies of two African buffalo (Syncerus caffer) populations in South Africa indicated substantial genome-wide genetic load due to high-frequency occurrence of deleterious alleles. The occurrence of these alleles, which negatively affect male body condition and bovine tuberculosis resistance, throughout most of the buffalo’s range were evaluated in this study. Using available microsatellite data (2–17 microsatellite loci) for 1676 animals from 34 localities (from 25°S to 5°N), we uncovered continent-wide frequency clines of microsatellite alleles associated with the aforementioned male traits. Frequencies decreased over a south-to-north latitude range (average per-locus Pearson r = -0.22). The frequency clines coincided with a multilocus-heterozygosity cline (adjusted R2 = 0.84), showing up to a 16% decrease in southern Africa compared to East Africa. Furthermore, continent-wide linkage disequilibrium (LD) at five linked locus pairs was detected, characterized by a high fraction of positive interlocus associations (0.66, 95% CI: 0.53, 0.77) between male-deleterious-trait-associated alleles. Our findings suggest continent-wide and genome-wide selection of male-deleterious alleles driven by an earlier observed sex-chromosomal meiotic drive system, resulting in frequency clines, reduced heterozygosity due to hitchhiking effects and extensive LD due to male-deleterious alleles co-occurring in haplotypes. The selection pressures involved must be high to prevent destruction of allele-frequency clines and haplotypes by LD decay. Since most buffalo populations are stable, these results indicate that natural mammal populations, depending on their genetic background, can withstand a high genetic load.

We explore the experience and meaning of being in an arranged male adult friendship for 7–10-year-old boys from single-mother families; we look at this from the perspective of the boys, their mothers, and their adult friends. In analyzing empirical material from a two-year fieldwork study, we draw on methodology and concepts from phenomenology. We propose that boy–adult friendships provide boys with a realization of masculine embodiment and reflect hierarchical masculinity, but that the presence of the male body is essential. We discuss how the analysis contributes to the literature on adult–child friendships, particularly between boys and male nonrelative adults, and to that on masculinity and boyhood studies, exploring boys’ embodiment from a phenomenological perspective.

Historically, Western hegemonic order has been established through cultivating and legitimating social categories of difference. Schools, among other institutions, reinforce difference through marking ability, race, and gender to signify which bodies are productive, deficient, or dangerous and therefore in need of control. This process of differentiation and control is evident in the social, political, and education contexts of disabled youth whose race, gender, and sexuality are read, controlled, and resisted through policy and pedagogy. Through the processes of hypervisiblity, pathologization, and underserving of Black girls in schools, and especially within special education, this animates the nexus of gender, race, and disability. Parallels are drawn to paradigms of the female body and femininity, where difference is constructed as inferior to the normative male body. Similarly, special education policy, practice, and literature conceptualize disability as subtractive difference, wherein what is considered a “deficit” relies on a subtractive interpretation of a normative body or a normative way of being. In this regard, disability, gender—and, crucially, race—are often thought of as a negative departure from a normalized embodiment. In special education, such normalized, essentialist approaches to gender, race, and disability contribute to the disproportionate overidentification of some social identities and the underidentification of others, most often along raced and gendered lines. Importantly, disabling processes are institutionalized in education through the mechanism of special education, which not only serves as an instructional and academic response to a student’s disability but also acts as an institutional process that determines a student as disabled. The determination of a student having a disability is mediated through law, policy, and interpersonal interaction between school professionals and parents and caregivers. Disproportionate identification has been the focus of research, and studies show that overidentification occurs most often in disability categories that are considered “subjective”: for instance, specific learning disabilities and emotional disturbances. Such identification has an impact on students’ learning; opportunities to interact with their peers in general education settings; access to high quality, challenging curriculum; and opportunities to engage critical thinking in educational activities that go beyond direct instruction. Disabling processes in schools related to the intersection of disability, gender, and race, in particular, are mediated by the local, cultural interactions of school personnel and are evident in the ways in which Black girls, in particular, are disabled in school.

Abstract Context The impact of parental overweight/obese on cumulative live birth rate in IVF/ICSI using a freeze-all strategy is still unknown. Objective To explore the effect of parental BMI on CLBR in a freeze-all strategy over 1.5 years. Design A retrospective study. Setting Tertiary-care academic medical center Patients or Other Participants 23482 patients (35289 FET cycles) were divided into four groups according to Asian BMI classification. Intervention(s) None. Main Outcome Measure(s) CLBR. Results Female overweight/obesity had the lower tendency in CLBR (groups1-4: optimistic: 69.4%, 67.9%, 62.3%, and 65.7%; conservative: 62.9%, 61.1%, 55.4%, and 57.6%) and the prolonged time (groups 1-4: 11.0, 12.2, 15.9, and 13.8 months for 60% CLBR in optimistic method; 8.7, 9.5, 11.7, 11.0 months for 50% CLBR in conservative method). The same trend with less extent was also observed in male BMI groups. When combining parental BMI, “parental overweight/obesity” had lower CLBR and longer time for reaching CLBR&gt;50% (optimistic: 4.5 months for 60% CLBR; conservative: 3 months for 50% CLBR), the next was “only female high BMI” (optimistic: 2.1 months for 60% CLBR; conservative: 1.7 months for 50% CLBR), while “only male high BMI” couldn’t influence these. Conclusions Our results firstly showed that the priorities of parental BMI, female BMI and male BMI on affecting the 1.5-year CLBR in freeze-all strategy, and the postponed time to reach up the certain CLBR (60% in optimistic, 50% in conservative) for overweight and obese patients was only several months, not so uncertain and long as losing weight.

The basis of the pathogenesis of male infertility is the processes of peroxide oxidation of biological substrates, especially lipids and proteins. By destroying the sperm membrane, toxic peroxidation products reduce its motility and ability to fertilize the egg, which is determined by a decrease in the number of motile sperm in the ejaculate. These changes lead to complete or partial male infertility. The authors of the review found that is accompanied by a damaging effect on the structural and functional activity of the gonads and is manifested, in particular, by an imbalance in the hormonal background of the male body. Similar effects are characteristic of an increase in the content of reactive Nitrogen species and its metabolites, which cause nitrosative stress, which is also the cause of male hypofertility and is inseparable from the state of oxidative stress. In scientific work it is determined that the accumulation of harmful peroxidation products leads to damage and destruction of sperm DNA, reduced activity of acrosomal enzymes and mitochondrial potential of sperm, reduced overall antioxidant activity. This makes it impossible for an adequate response of the body. Multi component antioxidant defense system resists stress. It is represented by enzymatic and non-enzymatic links, which can neutralize harmful radicals and peroxidation products. It contributes to the full manifestation of reproductive function. The presence of powerful antioxidant properties of catalase, superoxide dismutase, and enzymes of the thiol-disulfide system, which form the enzymatic system of antioxidant protection, as well as selenium, zinc, copper, other trace elements, retinol, tocopherol, ascorbic acid, and vitamins as parts of the non-enzymatic system is shown. The efficiency of registration is substantiated thin biochemical shift detectors or complex methods, such as total antioxidant status of sperm or sperm plasma, mitochondrial membrane potential, etc along with simple markers of oxidative stress, such as diene conjugates, malonic dialdehyde, and metabolites of the Nitrogen Oxide cycle. Given the leading role of oxidative stress in the development of male hypofertility, the prospect of further research is the search for modern means for correction, especially among substances with pronounced redox activity

Reading through the concept of shenti (body–self), this article examines the everyday processes by which Chinese young men make sense of and articulate ideal embodied masculinity as situated in different relationships. Drawing on 30 in-depth interviews with urban young men, I argue that the Chinese masculine self is essentially constitutive of and constructed through shenti during the men’s ordinary daily experiences. I highlight the relational formation of shenti as lying at the core of constructing ideal Chinese manhood, teasing out the different layers of body–self and relationality underpinning an individual man’s bodily practices and social interactions. Engaging with traditional cultural values of the ideal body–self and a feminist interactionist approach to gendered embodiment, shenti provides an important analytical lens that will enable us to expand ethnocentric discourses of the sociology of the gendered body by revealing the embodied and experiential aspects of culture in everyday practices. In doing so, this article contributes to enriching the existing debates around cultural variations in the male body and embodied masculinity by offering a Chinese perspective.

Male mate choice occurs in several animal species, but we know little about the factors that influence the expression of this behaviour. Males vary in their capacity to acquire mates (i.e. male quality), which could be crucial to male mate choice expression but it is often overlooked. Using a meta-analytical approach, we explore inter-individual variation in the expression of male mate choice by comparing the mating investment of males of different qualities and phenotypes to high- and low-quality females. We used two datasets that together contained information from 60 empirical studies, comprising 52 species. We found that males of all qualities and phenotypes prefer high-quality females, but differ in the strength of such preference. High- and medium-quality males are choosier than low-quality males. Similarly, males that are larger or in greater body condition are choosier than their counterparts. In contrast, male body mass and age are not associated with changes in male mate choice. We also show that experimental design may influence our understanding of male mating investment patterns, which may limit the generalization of our findings. Nonetheless, we argue that male quality may be an important feature in the expression of male mate choice.
