Background and Objectives: Genitourinary syndrome of menopause (GSM), previously known as vulvovaginal atrophy, is a chronic, progressive hypoestrogenic condition affecting vulvovaginal, urinary and sexual health in women. Common symptoms include vaginal dryness, itching, dyspareunia, urinary urgency and recurrent urinary tract infections (UTIs). Despite the high prevalence, GSM is underdiagnosed and undertreated, thereby negatively impacting women’s quality of life. To illustrate the practical aspects of GSM diagnosis and provide evidence-based management, we present a case-based narrative review synthesizing recently published, high-quality evidence. Materials and Methods: Evidence was drawn from multiple sources through targeted searches of databases, and included the 2025 AUA/SUFU/AUGS guideline (AUA), the 2024 NICE network meta-analyses (NICE), a 2025 systematic review/meta-analysis in breast-cancer survivors, the 2020 Menopause Society GSM Position Statement, the 2018 NAMS/ISSWSH breast cancer consensus, several primary source citations and other high quality peer-reviewed publications. Results: Five illustrative composite case vignettes of GSM are presented to highlight the evaluation strategy and evidence-supported treatment choices. Nonhormonal options are the first line treatments for mild GSM symptoms, either with or without the addition of vaginal estrogen therapy. For moderate to severe GSM, low-dose vaginal estrogen, vaginal DHEA, and ospemifene are all effective FDA-approved options. In breast cancer survivors, individualized decisions with oncology input are warranted. Maximal caution and a shared decision-making approach is required for women using Aromatase Inhibitors (AIs) for breast cancer risk reduction when choosing treatments for GSM. Conclusions: Treating GSM improves vaginal, sexual and urinary outcomes and quality of life of women. Clinicians need to proactively screen for GSM and offer evidence-based treatment options. The treatment decisions in breast cancer survivors are nuanced, requiring a shared-decision approach. Full article

Background/Objectives: Pelvic floor disorders (PFDs), which include pelvic organ prolapse and urinary incontinence, are common conditions that often affect sexual health, but remain under-assessed within routine care. The following cases are presented to demonstrate the potential of a brief sexual health questionnaire in pelvic floor clinics and to explore how sexual function varies across common PFD phenotypes. Methods: A pilot case series was conducted with a group of five sexually active women diagnosed with PFDs at the Materno-Infantil University Hospital in Gran Canaria, Spain, between January and December 2025. Patients completed the Female Sexual Function Index (FSFI) at the index visit. Results: Mean age was 40.6 years (range 35–46), mean parity was 1.6 births and 60% were active smokers. Mean FSFI total score was 26.9 (range 21.4–32.2) and 60% scored below 26.55. Desire and arousal were relatively preserved (means 5.0 and 4.9), whereas lubrication (3.4) and satisfaction (3.9) showed greater variability. Pain scores were low overall (mean 5.2). Self-rated sexual satisfaction was low in 40%, moderate in 40% and high in 20%. Moderate-to-high anticipatory sexual anxiety was present in 80%. Conclusions: Integrating a concise questionnaire based on the FSFI into the pelvic floor consultation appears to be a reasonable approach, with the potential to address secondary sexual dysfunction in patients with PFD, thereby facilitating personalised counselling and treatment.

Suicidal behaviors constitute a major global public health problem, with sexual minority groups showing a higher risk of engaging in such behaviors. This study aimed to analyze the influence of hopelessness, life satisfaction, and spirituality on suicide risk according to self-reported sexual orientation. A total of 532 individuals participated (M = 31.15 years, SD = 12.002). Of these, 39.8% identified as heterosexual, 34.2% as gay or lesbian individuals, and 25.9% as bisexual. Participants were assessed using the Plutchik Suicide Risk Scale, Beck’s Hopelessness Scale, the Beliefs and Values Scale, and Diener’s Satisfaction with Life Scale. The results indicate that 52.9% of bisexual participants and 41.2% of gay and lesbian participants presented a high suicide risk, compared with 15.6% of heterosexual participants. Individuals with a high suicide risk reported higher levels of hopelessness (p < 0.001), lower levels of life satisfaction (p < 0.001), and similar levels of spirituality. The proportion of variance explained in suicide risk was 42.8% among bisexual participants, 34.2% among gay and lesbian participants, and 29.9% among heterosexual participants. Hopelessness predicted a similar proportion of across groups (β = 0.446 in heterosexuals, β = 0.447 in gays and lesbians, and β = 0.457 in bisexuals). Life satisfaction showed a protective predictive effect, with β = −0.241 in bisexual participants, followed by gay and lesbian participants (β = −0.186) and heterosexual participants (β = −0.137). Spirituality was significant only among gay and lesbian participants (β = 0.133) and bisexual participants (β = 0.214). Sexual minority groups exhibited a higher risk of suicide, with life satisfaction—but not spirituality—acting as a protective factor. Full article

Curbing pornography consumption is the subject of keen debate and the object of numerous social efforts. The methods of structuring the discourse on combatting pornography use reveal a wide range of sociocultural views. This study utilizes semiotic and textual analyses of videos and advertisements (ads) dedicated to preventing pornography use in the secular and religious sectors of the Israeli Jewish public, which illuminates the differing perceptions and social norms among these groups. To this end, we conducted a comparative study of ads aimed at both audiences. By analyzing their symbolic representations and the rhetoric emerging from their content, we discovered that, while the prohibition narrative for the observant religious public centers on pornography use negatively impact the individual’s environment (their relationship family and community), the ads designed for viewing by the secular public focus on the individuals themselves. Thus, divergent socio ethical perspectives on the use of pornography emerge, illuminating how individuals relate to both their environment and their sense of self. The present study teaches us how different communities adapt words and symbols to convey social messages, particularly those associated with charged issues such as sexuality. Full article

Scoliidae are fossorial aculeate wasps (Hymenoptera: Apocrita) whose larvae develop as parasitoids of beetle grubs, mainly from the family Scarabaeidae. Despite their distinctive appearance and economic importance, the taxonomy and biology of Scoliidae are less well understood compared to other Hymenoptera. Recently, a new species of Scoliidae, Dielis tejensis Szafr., was described based on about a dozen male specimens from Texas (Nearctic realm). This article reports on mtDNA-verified discovery of the female D. tejensis. As in the case of other members of the tribe Campsomerini, D. tejensis exhibits strong sexual dimorphism in body structure and color pattern. Females of D. tejensis most closely resemble Dielis plumipes (Drury) and were previously confused with D. plumipes fossulana (Fabr.), with which D. tejensis is partially sympatric. D. tejensis has more than one generation per year, characterized by a male-biased sex ratio, perhaps resulting from the female immature stages entering a state of aestivation. The multi-generational developmental cycle of D. tejensis correlates with the existence of a partial seasonal polyphenism in this species. The data presented also shows a similarity in the distribution ranges of D. tejensis and one of its main nectaring plants, Hymenopappus artemisiifolius DC (Asteraceae), that may suggest similarity in the environmental requirements of both organisms or specialized trophic relationship between the still-unknown beetle host of the wasp larvae and H. artemisiifolius or another plant with a similar range. D. tejensis has been included in the accordingly modified key to the Nearctic species of Dielis Sauss. & Sichel, which is also presented here. Full article

Treponema pallidum is the etiological cause of syphilis, and in recent years, reemergence has been reported, especially among men who have sex with men and people living with HIV (PLWH). Certain cytokines may act as hallmark biomarkers in the progression of syphilis in PLWH, and studying how the immune system works against T. pallidum is important, especially in PLWH, whose immune system is compromised. We evaluated the serum expressions of IFN, TNF, IL-10, TGF-β1 and IL-17 in men living with HIV (MLWH) and their association with distinct stages of syphilis. We recruited MLWH from March to October 2022. A blood sample was requested, syphilis was detected using the reverse algorithm, and antibodies were titrated to determine the stage. Each of the cytokines studied was quantified using commercial ELISA kits. The following groups were formed: active syphilis (n = 217), cured syphilis (n = 134), and without syphilis (n = 159). The prevalence of elevated TGF-β1 differed between groups, being highest in individuals with active syphilis (51.6%; median 319 pg/mL), followed by those with cured syphilis (41.0%; median 137.0 pg/mL). Younger participants and persons without a history of sexually transmitted infections were more likely to present with high TGF-β1 levels. TGF-β1 may act as a biomarker in active syphilis and could suppress the inflammatory response against spirochetes. Full article

Background/Objectives: Mucuna pruriens (Linn.) DC. var. pruriens is a leguminous plant whose seeds have been used in traditional medicine, including for the enhancement of sexual function. However, scientific evidence regarding its toxicological safety remains limited. Accordingly, the present study aimed to investigate the acute and chronic oral toxicity of the ethanolic seed extract of M. pruriens var. pruriens in Sprague–Dawley rats. Methods: Acute oral toxicity was assessed in female rats following a single oral administration of the ethanolic seed extract of M. pruriens var. pruriens at a dose of 5000 mg/kg body weight, with animals monitored for general behavior, clinical signs, and mortality over a 14-day period. Chronic oral toxicity was evaluated in female and male rats administered the ethanolic seed extract of M. pruriens var. pruriens at doses of 100, 500, and 2500 mg/kg body weight daily for 270 days. Animals were monitored for general behavior, clinical signs, and health status throughout the study. Hematological, blood chemistry, gross pathological, and histopathological assessments were conducted at study termination. Results: In the acute oral toxicity study, no mortality or treatment-related behavioral abnormalities or clinical signs were observed in female rats receiving the ethanolic seed extract of M. pruriens var. pruriens, and findings were comparable to those of the control group. In the chronic oral toxicity study, no mortality occurred in any treatment group. Although statistically significant increases or decreases were observed in certain body weight, organ weight, hematological, and blood biochemical parameters compared with the control group, all values remained within established reference ranges. When considered together with the absence of abnormal behavioral changes, clinical signs, and gross pathological or histopathological alterations in major organs, these findings indicate that long-term oral administration of the ethanolic seed extract of M. pruriens var. pruriens did not result in chronic toxicity. Conclusions: The ethanolic seed extract of M. pruriens var. pruriens did not produce acute or chronic oral toxicity in Sprague–Dawley rats. Nevertheless, further clinical investigations are recommended to confirm its long-term safety for human use. Full article

Background/Objectives: When analyzing human skeletal remains for human identification, the assessment of sexual dimorphism is fundamental because it underlies sex estimation, a key parameter of the biological profile, which reduces the number of candidates to approximately one half. Ideally, the most dimorphic bones (the pelvis and long bones) are used, but this analysis may be compromised when the skeletal remains are badly preserved, which is often the case in older skeletons. It is, therefore, necessary to investigate sexual dimorphism in alternative skeletal elements as the quantity and quality of bone structures present in ancient skeletons represent crucial aspects when assessing biological differences between the sexes. The present study aims to evaluate the degree of sexual dimorphism in selected skeletal elements as a preliminary step toward identifying sexually dimorphic parameters with potential applicability in future research on poorly preserved skeletons. Methods: A metric assessment of sexual dimorphism was performed on the clavicle, sternum, and seventh cervical vertebra from a 20th Century collection of identified skeletons from the Portuguese population from CESPU (CEIC), showing a variable degree of bone preservation. Results: Our preliminary data suggest that although all bones analyzed may have exhibited some degree of sexual dimorphism, five parameters—sternal body length, manubrium width, first stern-vertebrae width, clavicle maximum length, and cervical vertebral body height—showed the most promising results. Nevertheless, further studies are needed to validate these observations, using a bigger sample of badly preserved bones. Conclusions: These results represent a preliminary assessment of sexually dimorphic parameters, which may be of interest in circumstances where skeletal elements are poorly preserved. Full article

Background/Objectives: The human larynx exhibits marked sexual dimorphism and undergoes age-related structural remodeling, both of which influence voice characteristics and have important implications for diagnostic assessment. While sex-related differences in laryngeal size are well recognized, the extent to which aging contributes to dimensional versus qualitative structural changes remains incompletely defined. This study aimed to analyze sex- and age-related morphometric and histological characteristics of the human larynx, with a focus on features relevant to voice evaluation and diagnostic interpretation. Methods: A cross-sectional anatomical study was conducted on 80 cadaveric human larynges preserved in 10% buffered formalin. Specimens were stratified by sex and age (<30, 30–60, and ≥60 years). Direct morphometric measurements included anteroposterior laryngeal length, thyroid cartilage height, thyroid angle, and relative glottic area. Epiglottic morphology and the presence of laryngeal cartilage calcification/ossification (binary classification: present vs. absent) were recorded. Histological analysis of vocal fold tissue was performed on a stratified subset of specimens. Statistical analysis included t-tests, chi-square tests, two-way ANOVA, effect size estimation, and logistic regression. Results: Male specimens showed significantly greater anteroposterior length, thyroid cartilage height, and relative glottic area, along with a narrower thyroid angle, compared with females (all p < 0.001), with large effect sizes. Age did not significantly influence overall laryngeal dimensions. In contrast, cartilage calcification/ossification increased markedly after the age of 60. Logistic regression identified age ≥ 60 years as the only independent predictor of calcification (OR = 4.37, p = 0.039), while sex was not significant. Epiglottic morphology demonstrated a sex-dependent distribution. Histology revealed age-related muscle atrophy and reduced collagen and elastin density. Conclusions: Sex defines the baseline morphometric framework of the adult larynx, whereas aging, particularly beyond 60 years, drives qualitative structural degeneration. These findings provide a reproducible anatomical reference for distinguishing sex-related variation from age-related changes in diagnostic assessment. Full article

Background: Pediatric salpingitis is rare and often underrecognized, especially in non-sexually active girls in whom symptoms are non-specific and sexually transmitted infections are absent. Delayed diagnosis may increase the risk of complications. We aimed to characterize the clinical presentation, diagnostic features, management, and outcomes of pediatric salpingitis and to identify predisposing factors in non-sexually active pediatric patients. Methods: We retrospectively reviewed pediatric cases of radiologically or surgically confirmed salpingitis at a tertiary children’s hospital (2000–2025) and conducted a narrative review of published pediatric cases. Results: Ten non-sexually active girls were included (median age 12.8 years). Abdominal pain was the most common symptom (80%), followed by fever and gastrointestinal complaints (50% and 30%, respectively); two patients (20%) were asymptomatic. Hydrosalpinx or pyosalpinx was detected on ultrasound in 80%. A causative organism was identified in 30%, predominantly enteric or anaerobic flora. All patients received broad-spectrum intravenous antibiotics; half required procedural or surgical intervention. Clinical outcomes were favorable in all cases. The literature review identified 56 additional non-sexually active girls, most of whom were postmenarchal. Abdominal pain was the predominant presentation, and gastrointestinal or anatomical predisposing factors were common. Conclusions: Non-sexually transmitted salpingitis is an uncommon but clinically relevant condition in children. Its atypical and often subtle presentation in non-sexually active girls warrants heightened clinical awareness. Early imaging and attention to gastrointestinal or postsurgical antecedents can facilitate timely diagnosis. Further multicenter studies are needed to establish diagnostic criteria and clarify long-term reproductive outcomes. Full article

Background: The relationships between segmental body composition and multidimensional performance outcomes remain insufficiently characterized in adults with limited but regular physical activity. This study examined associations between body composition parameters and functional test performance, while identifying sex-based differences. Methods: Forty-seven adults (31 women, 16 men; age 48.04 ± 11.33 years) underwent segmental bioelectrical impedance analysis and functional assessments including handgrip strength, isometric plank endurance, and single-leg balance. Correlations and sex comparisons statistical tests were performed. Results: Strong positive correlations were observed between segmental muscle mass and handgrip strength (r = 0.74–0.84, p < 0.05), with moderate associations for plank endurance (r = 0.30–0.32, p < 0.05). Fat mass demonstrated inverse relationships with performance, particularly for plank endurance (r = −0.36 to −0.62, p < 0.05). Males exhibited significantly greater muscle mass (p < 0.01), superior handgrip strength (p < 0.01), and longer plank times (p = 0.01). Females presented higher fat mass in lower limbs (p < 0.01). Conclusions: Segmental muscle mass shows strong associations with strength and moderate associations with core endurance, while adipose tissue exhibits inverse relationships. Pronounced sexual dimorphism exists in both body composition and functional capacity. Full article

Background/Objective: Human papillomavirus (HPV) represents the most widespread sexually transmitted infection globally, with high-risk strains such as HPV16 driving a rising incidence of oropharyngeal squamous cell carcinoma (OPSCC), particularly in developed countries like the United States and United Kingdom. In the U.S., HPV16-associated OPSCC has surpassed cervical cancer as the most common HPV-related malignancy. Despite the availability of preventive vaccines, uptake remains suboptimal among adolescents and shifting sexual behaviors have contributed to increased disease burden. Early detection remains a major clinical challenge due to the absence of defined precursor lesions and the extended latency between viral exposure and disease onset. Most patients present with advanced-stage disease and no prior clinical history of pre-malignancy, limiting access to early-stage samples and hindering biomarker discovery. Methods: To address these limitations, we developed an in vitro HPV16 oral cancer model, using the three-dimensional organotypic raft culture system that simulates the progression of HPV16-transfected oral epithelium from precancerous states to malignant phenotypes. Results: Using HPV16-transfected human tonsil keratinocytes, we generated stratified and differentiated epithelia that mimic the biochemical and structural changes observed in vivo. This system enables detailed monitoring of epithelial differentiation, biochemical shifts, viral genome status, and key oncogenic and metabolic markers associated with HPV16-driven OPSCC. By aligning expression profiles with clinical datasets, we validated the model through the measurement of virologic markers linked to infection and progression, as well as tissue markers indicative of carcinogenic transformation. Conclusions: This model offers a promising tool for refining early detection strategies and evaluating potential clinical biomarkers, ultimately aiming to improve diagnostic precision and therapeutic outcomes in HPV-associated OPSCC.

Desire, a transformative force, is one of contemporary serial narratives’ most intricate and multifaceted dimensions. Far from being reducible to a mere representation of sexual attraction, desire in television seriality operates as a prism through which to explore issues of intimacy, identity, and power. This paper seeks to analyze how desire is staged and problematised within a set of emblematic series that have significantly shaped contemporary cultural imagination. Grey’s Anatomy explores the entanglement of desire with professional life, emotional fragility, and collective trauma, constructing narratives where eros intersects with affective labour and the negotiation of identity within high-pressure contexts. Sex and the City proposes a very different model, placing female desire at the centre as a space of autonomy, experimentation, and confrontation with the normative frameworks of late capitalist society. By contrast, The Handmaid’s Tale reimagines desire within a dystopian theocracy, assigning it an overtly political function: here, erotic impulses and affective attachments become acts of resistance against systemic repression and biopolitical control. More recently, Sex Education embodies a cultural shift, presenting desire through a plural and inclusive lens that embraces diversity of sexual orientation, gender identity, and relational practices. These case studies, when viewed collectively, reveal how television series rework cultural codes of sexuality and intimacy, producing new imaginaries of the body, pleasure, and identity. In this perspective, serial narratives emerge as key cultural laboratories, reproducing and challenging dominant ideologies of desire while offering audiences opportunities for recognition, critique, and affective engagement beyond the screen.

Background: In 2022, Romania experienced a sharp increase in hepatitis A virus (HAV) infections, with evidence of predominant fecal–oral transmission through sexual contact, raising concern for an outbreak among men who have sex with men (MSM). Methods: We conducted a prospective multicenter study between 1 March 2022 and 1 March 2023 in two tertiary hospitals in Bucharest. HAV infection was defined by a compatible clinical presentation, elevated liver enzymes, and positive anti-HAV IgM serology. Clinical and laboratory characteristics were compared by transmission route and HIV status. Results: A total of 191 patients were diagnosed with HAV, including 105 MSM and 86 with foodborne transmission. All were unvaccinated. Most patients were male (82.2%), with a median age of 30 years (IQR 24–38). MSM were significantly younger and reported higher-risk sexual behaviors, including chemsex and multiple or occasional partners (p < 0.0001). Among MSM, 48 (25.1%) were living with HIV, most with preserved immune status and undetectable viral loads. Clinical manifestations were similar across groups, with jaundice being most frequent (89.5%). However, MSM exhibited more severe hepatocellular injury, reflected by higher ASAT and ALAT levels and lower prothrombin concentration, independent of HIV status. MSM were also more likely to have concomitant sexually transmitted infections, including syphilis and mpox (p < 0.001). Disease was predominantly mild, although MSM had longer hospital stays. Conclusions: The 2022 HAV surge in Romania was driven by both sexual and foodborne transmission. Targeted HAV vaccination, along with integrated sexual health services and harm-reduction strategies, is essential to prevent future outbreaks. Full article

The Moroccan locust Dociostaurus maroccanus (Thunberg, 1815) (Orthoptera: Acrididae) is recognized as a serious pest of pastures and crops in many Mediterranean countries. So far, the identification of chemical compounds involved in intraspecific communication has been elusive, with only one male-specific compound, namely (2E,7R,11R)-3,7,11,15-tetramethylhexadec-2-enal (2E,7R,11R-phytal), proposed as candidate sex pheromone component. Previous works reported that males also release the sex-specific long-chain aldehydes tetradecanal and hexadecanal, although no evidence of their role in chemical signaling has been presented so far. Here we additionally report another male-specific compound, viz. pentadecanal, and also report the electroantennographic and behavioral responses of virgin and mated females to these three aldehydes. We first demonstrated that their release is age-dependent, with emission overall peaking at 1–2 weeks after fledging. Solid-phase microextraction analyses from male hind legs suggest that these aldehydes are released from this body part. Overall, the antennae of virgin and mated females exhibited a dose-dependent response to increasing concentrations of each aldehyde, except for the response of virgin females to hexadecanal. Significant differences were observed between virgin and mated females at all doses of hexadecanal, while the mating status did not influence the response to tetradecanal and pentadecanal. Furthermore, the behavioral response of females varied according to their mating status. Specifically, mated females showed a significant preference for tetradecanal and pentadecanal, whereas a slight but non-significant attraction to hexadecanal was observed on virgin females. These findings provide new insights into the sexual communication of the species, although further research is needed to decipher their ecological function, especially on mated females. Full article
