Diversity of Sexual Development

Sexual passion is an important element of adult romantic relationships, but little is known about how it is developed or expressed during adolescence. From a Self Determination Theory perspective, this study explored the connections between parents' sexual passion and children's sexual passion, and whether these links were mediated by parents' communication about sexuality with their children. Using a diverse sample of 484 mother-adolescent dyads (Mage  = 14.48, SD = 1.68, 50% female, 56% White), we specified a path model in a Structural Equation Modeling framework to test hypothesized associations...

OBJECTIVE: The purpose of this study was to explore the experiences of cultural competence and humility among patients of the lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA+) community in physical therapy. Researchers sought to understand the perspectives of adults over 18 years old who have received physical therapy and identify as a member of the LGBTQIA+ community. METHODS: A phenomenological qualitative approach was utilized for this study...

BACKGROUND: Transgender and gender diverse youth experience multiple disproportionate adverse sexual health outcomes. Sexual health education teaches knowledge, attitudes, and skills for promoting sexual health, including reducing risk for sexually transmitted infection, HIV acquisition, and unintended pregnancy. Provision of sexual health education may be protective, but research remains scarce. METHODS: We conducted a multi-stage thematic analysis of 33 in-depth interviews among transgender and gender diverse youth (ages 15-24) living in the southeastern United States on their sexual health education experiences...

Increasing rhetoric regarding the common intersection of autism and gender diversity has resulted in legislation banning autistic transgender youth from accessing standard of care supports, as well as legislative efforts banning all youth gender care in part justified by the proportional over-occurrence of autism. Yet, no study has investigated whether autistic and non-autistic transgender youth present fundamentally different gender-related phenotypes. To address this gap, we extensively characterized autism, gender diversity, and sexuality among autistic and non-autistic transgender binary youth (N = 66, Mage  = 17...

BACKGROUND: Most forcibly displaced persons are hosted in low- and middle-income countries (LMIC). There is a growing urbanization of forcibly displaced persons, whereby most refugees and nearly half of internally displaced persons live in urban areas. This scoping review assesses the sexual and reproductive health (SRH) needs, outcomes, and priorities among forcibly displaced persons living in urban LMIC. METHODS: Following The Joanna Briggs Institute scoping review methodology we searched eight databases for literature published between 1998 and 2023 on SRH needs among urban refugees in LMIC...

As diversity in the United States increases, marriage and family therapists are encountering more multi-heritage couples in therapy. Recent research shows that around 11% of adults are married to someone from a different racial or ethnic group, rising to 19% among new marriages. Multi-heritage couples encompass inherent differences in race, ethnicity, religion, gender, sexual orientation, national origin, and culture. This article addresses the unique challenges faced by multi-heritage couples in therapy and explores the strengths and weaknesses of existing assessment tools suitable for their needs...

Transposable elements and other repeats are repressed by small-RNA-guided histone modifications in fungi, plants and animals. The specificity of silencing is achieved through base-pairing of small RNAs corresponding to the these genomic loci to nascent noncoding RNAs, which allows the recruitment of histone methyltransferases that methylate histone H3 on lysine 9. Self-reinforcing feedback loops enhance small RNA production and ensure robust and heritable repression. In the unicellular ciliate Paramecium tetraurelia, small-RNA-guided histone modifications lead to the elimination of transposable elements and their remnants, a definitive form of repression...

OBJECTIVES: To determine the extent of career-long and 12-month exposure to sexual, physical and psychological/verbal violence committed by patients or their companions among physical therapists in Spain. Additionally, to identify the factors associated with such exposure. METHODS: This study employed an observational cross-sectional approach. Initially, a questionnaire was developed and validated using a convenience sample. Subsequently, it was distributed via e-mail to all physical therapists registered in Spain in the first quarter of 2022...

The Arab region is experiencing the largest youth cohort in its history. Parental influence is a clear factor in the well-being of this demographic. This scoping review serves as the first consolidated synthesis of existing research on parenting in the Arab world, aimed at identifying research gaps and informing future research agendas. Searches of 18 databases resulted in 4,758 records (1995-2018) in all languages. Using Arksey and O'Malley's methodological framework, eligible studies (n = 152) underwent duplicate data abstraction...

BACKGROUND: Sexual health is critical to overall health, yet sexual history taking is challenging. LGBTQ+ patients face additional barriers due to cis/heteronormativity from the medical system. We aimed to develop and pilot test a novel sexual history questionnaire called the Sexual Health Intake (SHI) form for patients of diverse genders and sexualities. METHODS: The SHI comprises four pictogram-based questions about sexual contact at the mouth, anus, vaginal canal, and penis...

PURPOSE: Satisfaction with life is a core aspect of successful aging, which is influenced by a broad range of factors, including health, socioeconomic status, and social relationships. Black lesbians experience various social challenges, including racism, sexism, ageism, and heterosexualism, that may present as deterrents to aging successfully. To develop better policies and programs in support of successful aging among all adults, an understanding of the unique components associated with their intersecting identities must be explored...

Sexual dimorphism allows species to meet their fitness optima based on the physiological availability of each sex. Although intralocus sexual conflict appears to be a genetic constraint for the evolution of sex-specific traits, sex-linked genes and the regulation of sex steroid hormones contribute to resolving this conflict by allowing sex-specific developments. Androgens and their receptor, androgen receptor (Ar), regulate male-biased phenotypes. In teleost fish, ar ohnologs have emerged as a result of teleost-specific whole genome duplication (TSGD)...

Ovarian follicle development is an essential process for continuation of sexually reproductive animals, and is controlled by a wide variety of regulatory factors such as neuropeptides and peptide hormones in the endocrine, neuroendocrine, and nervous systems. Moreover, while some molecular mechanisms underlying follicle development are conserved, others vary among species. Consequently, follicle development processes are closely related to the evolution and diversity of species. Ciona intestinalis type A ( Ciona rubusta ) is a cosmopolitan species of ascidians, which are the closest relative of vertebrates...

The endocrine and neuroendocrine systems exert powerful and broad control over the regulation of homeostasis in animals. Secreted hormones play significant roles in lifetime-related events such as germ cell development, sexual maturation, development, metamorphosis, aging, feeding, and energy metabolism. Additionally, hormones, particularly sex steroid hormones, are involved in reproduction, including sexual behavior and dimorphism. Changes in body color protect against external enemies, and circadian rhythms direct physiology and behaviors in synchrony with light and dark cycles...

UNLABELLED: Cryptococcus neoformans is a fungal pathogen responsible for >200,000 yearly cases with a mortality as high as 81%. This burden results, in part, from an incomplete understanding of its pathogenesis and ineffective antifungal treatments; hence, there is a pressing need to understand the biology and host interactions of this yeast to develop improved treatments. Protein palmitoylation is important for cryptococcal virulence, and we previously identified the substrates of its main palmitoyl transferase...

Spermatogonial stem cell (SSC) acquisition of meiotogenetic state during puberty to produce genetically diverse gametes is blocked by drugs collectively referred as 'puberty blocker' (PB). Investigating the impact of PB on juvenile SSC state and function is challenging due to limited tissue access and clinical data. Herein, we report largest clinically annotated juvenile testicular biorepository with all children with gender dysphoria on chronic PB treatment highlighting shift in pediatric patient demography in US...

Identifying the molecular origins by which new morphological structures evolve is one of the long standing problems in evolutionary biology. To date, vanishingly few examples provide a compelling account of how new morphologies were initially formed, thereby limiting our understanding of how diverse forms of life derived their complex features. Here, we provide evidence that the large projections on the Drosophila eugracilis phallus that are implicated in sexual conflict have evolved through co-option of the trichome genetic network...

Vaginal microbiota transplantation (VMT) is a cutting-edge treatment modality that has the potential to revolutionize the management of vaginal disorders. The human vagina is a complex and dynamic ecosystem home to a diverse community of microorganisms. These microorganisms play a crucial role in maintaining the health and well-being of the female reproductive system. However, when the balance of this ecosystem is disrupted, it can lead to the development of various vaginal disorders. Conventional treatments, such as antibiotics and antifungal medications, can temporarily relieve the symptoms of vaginal disorders...

BACKGROUND: Despite advances in human immunodeficiency virus (HIV) prevention methods, such as the advent of pre-exposure prophylaxis (PrEP), the number of people with newly acquired HIV remains high, particularly in at-risk groups. A prophylactic HIV vaccine could contribute to reduced disease prevalence and future transmission and address limitations of existing options, such as suboptimal long-term adherence to PrEPs. METHODS: This qualitative study aimed to capture perceptions towards and acceptance of prophylactic HIV vaccination in three adult populations in the United States: the general population, 'at-risk' individuals (e...

Purpose: Transgender and gender diverse (TGD) people assigned female at birth (AFAB) face numerous barriers to preventive care, including for cervical cancer screening. At-home human papillomavirus (HPV) testing may expand access to cervical cancer screening for TGD people AFAB. This study assessed the perceptions of TGD individuals AFAB who self-collected cervicovaginal and anal samples. Methods: We recruited TGD individuals AFAB to collect cervicovaginal and anal specimens at home using self-sampling for HPV testing, and individuals reported their perceptions of self-sampling...
