INTRODUCTION: Globally, transgender ("trans") women are one of the key populations most disproportionately impacted by HIV. Pre-exposure prophylaxis (PrEP) is the newest and most promising biomedical HIV prevention intervention to date. This paper reviews relevant literature to describe the current state of the science and describes the potential role of PrEP among trans women, including a discussion of unique considerations for maximizing the impact of PrEP for this vulnerable population...

Wolbachia are a group of intracellular bacteria that cause reproductive alterations in arthropods. Here, we describe the effects of two environmental factors (crowding and temperature) on phenotypic expression of feminization, the host's fecundity and Wolbachia infection intensity among life cycle stages in the naturally Wolbachia-infected copepod, Mesocyclops thermocyclopoides. The copepod was first found to be co-infected with Wolbachia A- and B-supergroups Wolbachia strains based on wsp primers. The relative Wolbachia infection intensity within individuals was determined using quantitative real-time PCR and was significantly higher in the B-supergroup than in the A-supergroup...

Transgender and gender-nonconforming individuals experience significant health disparities. They are more likely to use drugs and alcohol, smoke, be diagnosed with HIV infection or other sexually transmitted infections, and experience depression or attempt suicide. Many also experience discrimination within the health care system. Office-level strategies to create a safe and affirming space for gender-expansive patients include posting of a nondiscrimination statement, use of intake forms that ask about current gender identity and birth-assigned sex, provision of gender-neutral restrooms, and staff training in use of appropriate language...

Theory predicts unified sex ratios for most organisms, yet biases may be engendered by selfish genetic elements such as endosymbionts that kill or feminize individuals with male genotypes. Although rare, feminization is established for Wolbachia-infected Eurema butterflies. This paradigm is presently confined to islands in the southern Japanese archipelago, where feminized phenotypes produce viable all-daughter broods. Here, we characterize sex bias for E. hecabe in continental Australia. Starting with 186 wild-caught females, we reared >6000 F1-F3 progeny in pedigree designs that incorporated selective antibiotic treatments...

INTRODUCTION: Spironolactone and cyproterone acetate (CPA) are the two main antiandrogen medications used in feminizing hormone therapy in transgender women. Previous studies have suggested that these two agents might have opposite effects on high-density lipoprotein (HDL) level when used in this context, and limited data have suggested CPA increases prolactin more than spironolactone. AIM: To compare the effects of spironolactone and CPA on HDL and prolactin serum concentrations in transgender women...

Although it has been documented that miscarriage is a common pregnancy outcome and more likely to happen among women aged 35 years and older, there is very little research on the quality of such a lived experience. This study features phenomenological interviews of 10 women aged 35 years and older. Theoretical frameworks of ambiguous loss and feminism guide the design and analysis. The salient themes suggest that women experience miscarriage from a physical, emotional, temporal, and social context that includes intense loss and grief, having a sense of otherness, a continuous search for meaning, and feelings of regret and self-blame...

INTRODUCTION: One of the most serious known adverse effects of feminizing cross-sex hormone therapy (CSHT) is venous thromboembolism (VTE); however, no study has assessed the incidence of VTE from the hormone therapies used in the United States because previous publications on this topic have originated in Europe. CSHT in the United States typically includes estradiol with the antiandrogen spironolactone, whereas in Europe estradiol is prescribed with the progestin cyproterone acetate...

16α-hydroxyprogesterone (16OHP4) is not well characterised in terms of metabolism and receptor interaction. We therefore investigated its metabolism by adrenal CYP11B and peripheral steroidogenic enzymes, SRD5A and AKR1C2. UHPLC-MS/MS analyses identified novel steroids: the biosynthesis of 4-pregnen-11β,16α-diol-3,20-dione catalysed by CYP11B2; the 5α-reduction of the latter and 16OHP4 catalysed by SRD5A yielding 5α-pregnan-11β,16α-diol-3,20-diovne and 5α-pregnan-16α-ol-3,20-dione (16OH-DHP4); and 16OH-DHP4 converted by AKR1C2 to 5α-pregnan-3α,16α-diol-20-one...

AIM: To evaluate the outcomes of laparoscopic surgery for the treatment of adnexal pathology in older children and adolescents. METHODS: We retrospectively reviewed medical records of 69 pediatric and adolescent patients aged between 9 and 19 years who underwent laparoscopic surgery for adnexal pathology in a tertiary academic center in Istanbul, Turkey, from January 2005 through September 2015. Patients who were pregnant or had non-gynecology pathology detected during surgery were excluded from the study...

BACKGROUND: Androgen insensitivity syndrome or testicular feminization syndrome is a rare X-linked recessive disorder, which encompasses a wide range of phenotypes that are caused by numerous different mutations in the androgen receptor gene. Complete androgen insensitivity syndrome occurs when the body cannot use androgens at all. People with this form of the condition have the external sex characteristics of females, but do not have a uterus and therefore do not menstruate and are unable to conceive a child (infertile)...

INTRODUCTION: As gender dysphoria is becoming increasingly accepted in the general population, the number of patients seeking gender reassignment surgery is increasing. Although not every patient with gender dysphoria requires surgery, medical practitioners taking care of these individuals should be aware of the different surgical options. AIM: To review current gender reassignment surgical techniques and update the clinician. METHODS: A review of the literature was performed focusing on the most recent techniques of gender reassignment surgery...

INTRODUCTION: The surgical management of girls with masculinized genitalia is gradually changing towards a more conservative approach. Reports on loss of clitoral sensitivity and related impairment of sexual function in women after feminizing genital surgery in childhood have been pivotal in this evolution. An exposed clitoral glans is occasionally seen at follow-up, and while patients may complain of aesthetics, no clitoral discomfort secondary to glans exposure has been reported. A technique has been developed to reconstruct the clitoral hood and the present study reports the preliminary results...

The aim of this article is to demonstrate how women of color feminism predates and disrupts dominant dialogues in the field of White affect studies. I introduce the concept of White affect studies as an arena of inquiry that draws from Western-European theories and literatures and architects a sociopolitical structure of affect that positions White affects as universal. Scholars contributing to the field of White affect studies posit theories of affect, embodiment, subjectivity, phenomenology, violence, war, and more, while disregarding the theoretical contributions made by women of color feminism in thinking through these notions and social issues...

Xenopus laevis is an important model for detecting feminizing effects of endocrine disrupting chemicals (EDCs) on amphibians because its genetic males can be induced to phenotypic females by estrogenic chemicals. It is crucial that chemical exposures begin at sensitive developmental stages for gonadal sex-reversal in X. laevis. To determine the optimal stages for initiating exposures, we investigated gonadal sex-reversal induced by low concentrations of 17α-ethinylestradiol (EE2) when exposures were initiated at different stages (3/4, 45/46, 48 and 50) until stage 58...

For adolescents with gender dysphoria, it has become common to be offered hormonal treatment to either delay or suppress pubertal development and/or to masculinize or feminize the body. At the same time, it has been our clinical impression that the psychological vulnerability of at least some of these youth has been overlooked. Fifty consecutive referrals of adolescents with a DSM-IV-TR diagnosis of Gender Identity Disorder (GID) constituted the sample. Information obtained at intake was coded for the presence or absence of 15 psychosocial and psychological vulnerability factors...

In the present study, we investigated the occurrence of intersex condition, histopathological changes in the gonad and endocrine disruptor biomarker responses in Tilapia species (Tilaipia guineensis, Sarotherodon galileaus and Oreochromis niloticus) along the Ogun River, Nigeria. The study sites covered a length of 320 km and a total of 1074 tilapias were collected from three sampling sites (Abeokuta, Isheri and Ikorodu) with different degrees of anthropogenic contamination. Samples were also collected from an upstream putative control site (Igboho) along the Ogun River...

Alternative morphotypes have been reported less frequently in females than in males. An exception to this rule is the gradient of phenotypical masculinization reported in some female mammals, in which feminized and masculinized females represent two opposite ends along this gradient. These phenotypical differences originate during prenatal development as the consequence of maternal effects. Feminized and masculinized females differ in several traits, including morphological, physiological, behavioral, and reproductive traits...

The aim of this study was to determine whether treatment of male CBA/H mice with 17β-estradiol (E2) had protective effect on survival and hepatic oxidative damage of lipids and proteins against hyperoxia. Furthermore, we wanted to explore the effect of E2 treatment on the expression of sex-specific cytochrome P450 isoforms, and their possible involvement in E2-induced resistance to hyperoxia. Lipid peroxidation and protein carbonylation were analysed spectrophotometrically and were used as a measure of lipid and protein oxidative damage...
