Malignant feminizing adrenocortical tumors are exceedingly rare. Their main presentation is gynecomastia. In these estrogen secreting tumors (with or without other adrenocortical hormones) lack of gynecomastia is exceptional as in our case. A 44-year-old man presented with abdominal pain. Radiological assessment revealed a tumor measuring 120 × 95 mm in the retroperitoneal area with numerous metastases. Pathological examination pleaded for an adrenal origin with a Weiss's score of 5. Six months later, the tumor relapsed, and he had a second surgery and was sent for hormone assessment...

Sexual fate of the sawfly, Athalia rosae (Hymenoptera: Tenthredinidae) is determined by the complementary sex determination (CSD) mechanism as is the case in honeybees. However, to date, genes involved in sex determination have not been identified in this species. In this study, we attempted to identify orthologs of complementary sex-determiner (csd), feminizer (fem), and doublesex (dsx) from the A. rosae genome, all of which are crucial components of the sex determination cascade in the honeybee. As a result, we identified a sawfly ortholog of dsx (designated as Ardsx)...

The sexological roots of "lesbian" and the "queer" turn from biologized categories of sexual difference pose an exciting set of questions and tensions for thinking about queer feminism and biological meanings. This issue seeks to open space to explore how we might reconcile assumptions about "female same-sex sexuality" that often accompany "lesbian" with queer and trans-feminist treatments of science, embodiment, and desiring, while at the same time insisting on the importance of an undertheorized dyke legacy for thinking the at-once material and political nature of sexuality...

Although maternally transmitted microorganisms such as Wolbachia are well known to have a variety of effects on the reproduction of diverse insect species, little is known about the underlying mechanisms of actions. Artificial transfer of Wolbachia between taxonomically distant host species may provide insights into Wolbachia-induced manipulations of hosts. Here we performed a cross-order transfer of feminizing Wolbachia derived from a butterfly, Eurema mandarina. The Wolbachia were propagated in the Eurema hecabe cell line, called NTU-YB, and then used to inject prepupal/pupal females of a Wolbachia-free hymenopteran sawfly, Athalia rosae...

OBJECTIVE: Approximately 25 million individuals older than age 15 identify as transgender, representing about 0.3-0.9% of the world's population. The aim of this paper is to identify and describe important medical and social considerations facing transgender persons with epilepsy. METHODS: We performed literature searches on the following terms: transgender AND epilepsy, transgender AND neurology, gender dysphoria AND epilepsy, gender dysphoria AND neurology. We also performed literature searches for common feminizing or masculinizing treatment regimens, and searched for interactions of those treatment regimens with antiepileptic drugs (AEDs) and with seizures...

REVIEW
Claus Wedekind
During sex determination, genetic and/or environmental factors determine the cascade of processes of gonad development. Many organisms, therefore, have a developmental window in which their sex determination can be sensitive to, for example, unusual temperatures or chemical pollutants. Disturbed environments can distort population sex ratios and may even cause sex reversal in species with genetic sex determination. The resulting genotype-phenotype mismatches can have long-lasting effects on population demography and genetics...

REVIEW
Richard Cordaux, Clément Gilbert
An increasing number of horizontal gene transfer (HGT) events from bacteria to animals have been reported in the past years, many of which involve Wolbachia bacterial endosymbionts and their invertebrate hosts. Most transferred Wolbachia genes are neutrally-evolving fossils embedded in host genomes. A remarkable case of Wolbachia HGT for which a clear evolutionary significance has been demonstrated is the "f element", a nuclear Wolbachia insert involved in female sex determination in the terrestrial isopod Armadillidium vulgare...

Understanding genome and gene function in a whole organism requires us to fully comprehend the life cycle and the physiology of the organism in question. Caenorhabditis elegans XX animals are hermaphrodites that exhaust their sperm after 3 days of egg-laying. Even though C. elegans can live for many days after cessation of egg-laying, the molecular physiology of this state has not been as intensely studied as other parts of the life cycle, despite documented changes in behavior and metabolism. To study the effects of sperm depletion and aging of C...

Inspired by Lynne Huffer's queer feminist genealogy, this article explores queer-trans-feminism as a project that would bring together queer, feminist, and transgender theory and politics into a shared critical lineage. I suggest that Monique Wittig is a neglected thinker who could re-enliven connections and debates within queer, feminist, and trans theory and politics. Utilizing recent historiographies of queer and feminist theory, I imagine what it would mean to hold on to the figure of the lesbian as a figure for queer-trans-feminist politics rather than render the lesbian anachronistic...

The author reviews Elizabeth A. Wilson's Gut Feminism (2015), arguing that Wilson's book productively challenges some of feminist theory's most entrenched presuppositions: that social, cultural, and discursive frameworks are opposed and superior to biological ones; that biological matter is flat, sovereign, monolithic, and determining; that depression is more a cultural, historical, and psychological phenomenon than a biochemical and pharmaceutical one (and that these nominative distinctions are stable and natural); and finally, that the belly's ruminations (hunger, ingestion, digestion, peristalsis, diarrhea, constipation, and excretion) give no clue as to the complexities of entanglements between gut, psyche, subjectivity, sociality, and hostility...

To mark the 30th anniversary of the publication of Scarborough and Furumoto's classic work Untold Lives, and to honor the intellectual legacy of Elizabeth Scarborough (1935-2015), we introduce this special issue devoted to the histories of women, gender, and feminism in psychology. We provide a short biographical sketch of Elizabeth, highlighting her own marriage-career dilemma, then contextualize the publication of Untold Lives within the historiography on women in psychology at that time. We conclude by discussing intersectionality as an analytic framework for the history of psychology as a way to extend and enrich this historiography...

Human papillomavirus (HPV) can cause a number of anogenital cancers (i.e., cervical, penile, anal, vaginal, vulvar) and genital warts. A decade ago, the HPV vaccine was approved, and has been shown to be a public health achievement that can reduce the morbidity and mortality for HPV-associated diseases. Yet, the mistaken over-identification of HPV as a female-specific disease has resulted in the feminization of HPV and HPV vaccines. In this critical review, we trace the evolution of the intersection of science, politics, economics and gender norms during the original HPV vaccine approval, marketing era, and implementation...

A key strand in the Western literature on working-class masculinities focuses on whether young men are capable of the feminized performances apparently required of them in new service economies. However, the wider literature on processes of neoliberalization - emphasizing the 'hollowing out' of labour markets, the cultural devaluation of lower-skilled forms of employment, and the pathologization of working-class lives - would suggest that it is as much a classed as a gendered transformation that is demanded of young men leaving school with few qualifications...

Sex is determined by temperature during embryogenesis in snapping turtles, Chelydra serpentina. Previous studies in this species show that dihydrotestosterone (DHT) induces ovarian development at temperatures that normally produce males or mixed sex ratios. The feminizing effect of DHT is associated with increased expression of FoxL2, suggesting that androgens regulate transcription of FoxL2. To test this hypothesis, we cloned the proximal promoter (1.6kb) and coding sequence for snapping turtle FoxL2 (tFoxL2) in frame with mCherry to produce a fluorescent reporter...

Leydig cell tumors (LCTs) are rare testicular tumors. Incidence is 1%-3% of all testicular neoplasms, bilateral in 10%. They are frequently hormonally active, leading to feminizing or virilizing syndromes. LCTs can be either pure or mixed with germ cell tumors or other sex cord-stromal tumors. Here, we are reporting a benign pure LCT in a 6-year-old boy presented with pseudopuberty.

Sex-dependent pituitary GH secretory profiles--pulsatile in males and persistent in females--regulate sex-biased, STAT5-dependent expression of hundreds of genes in mouse liver, imparting sex differences in hepatic drug/lipid metabolism and disease risk. Here we examine transcriptional and epigenetic changes induced by continuous-GH infusion (cGH) in male mice, which rapidly feminizes the temporal profile of liver STAT5 activity. cGH repressed 86% of male-biased genes and induced 68% of female-biased genes within 4-days; however, several highly female-specific genes showed weak or no feminization, even after 14-days cGH...

Sex assignment in 46XY genetic male children with congenital inadequacy of the penis (CIP) is controversial. Traditionally, children with penile length less than 2 cm at birth are considered unsuitable to be raised as males. They are typically re-assigned to female-sex and feminizing genitoplasty is usually done in infancy. However, the concept of cerebral androgen imprinting has caused paradigm shift in the philosophy of sex re-assignment. Masculinization of the brain, rather than length of the penis, is the modern criterion of sex re-assignment in CIP...

Excess estrogen exposure of avian embryos perturbs reproductive organ development in both sexes and demasculinizes the reproductive behaviors of adult males. We have previously shown that these characteristic effects on the reproductive organs also can be induced by exposure of Japanese quail (Coturnix japonica) embryos to selective agonists of estrogen receptor alpha (ERα). In contrast, the male copulatory behavior is only weakly affected by developmental exposure to an ERα agonist. To further elucidate the respective roles of ERα and ERβ in estrogen-induced disruption of sexual differentiation, we exposed Japanese quail embryos in ovo to the selective ERα agonist 16α-lactone-estradiol (16αLE2), the selective ERβ agonist WAY-200070, or both substances in combination...

In vertebrates, the primary sex-determining signals that initiate sexual development are remarkably diverse, ranging from complete genetic to environmental cues. However, no sex determination-related genes have been functionally identified in reptiles. Here, we characterized a conserved DM domain gene, Dmrt1, in Chinese soft-shelled turtle Pelodiscus sinensis (P. sinensis), which exhibits ZZ/ZW sex chromosomes. Dmrt1 exhibited early male-specific embryonic expression, preceding the onset of gonadal sex differentiation...
