This study examined reactions to first postpubertal same-sex sexual experience in the Kinsey female same-sex sample (consisting of females with extensive postpubertal same-sex experience) as a function of participant and partner ages. As such, it complemented the Rind and Welter (2016) study, which examined the same in the Kinsey male same-sex sample. Data were collected by Kinsey interviewers between 1939 and 1961 (M year = 1947). Girls under 18 (M age = 14.9), whose sexual experience was with a woman (M age = 26...

Sexual dimorphism is an interesting biological phenomenon. Previous studies showed that DNA methylation might play a role in sexual dimorphism. However, the overall picture of the genome-wide methylation landscape in sexually dimorphic species remains unclear. We analyzed the DNA methylation landscape and transcriptome in hybrid tilapia (Oreochromis spp.) using whole genome bisulfite sequencing (WGBS) and RNA-sequencing (RNA-seq). We found 4,757 sexually dimorphic differentially methylated regions (DMRs), with significant clusters of DMRs located on chromosomal regions associated with sex determination...

Opposite-sex attraction in most mammals depends on the fine-tuned integration of pheromonal stimuli with gonadal hormones in the brain circuits underlying sexual behaviour. Neural activity in these circuits is regulated by sensory processing in the accessory olfactory bulb (AOB), the first central station of the vomeronasal system. Recent evidence indicates adult neurogenesis in the AOB is involved in sex behaviour; however, the mechanisms underlying this function are unknown. By using Semaphorin 7A knockout (Sema7A ko) mice, which show a reduced number of gonadotropin-releasing-hormone neurons, small testicles and subfertility, and wild-type males castrated during adulthood, we demonstrate that the level of circulating testosterone regulates the sex-specific control of AOB neurogenesis and the vomeronasal system activation, which influences opposite-sex cue preference/attraction in mice...

BACKGROUND: Monsplasty treats massive weight loss (MWL) patients with redundant tissues in the mons region. Monsplasty, however, is not a routine component of abdominal contouring. OBJECTIVES: The goal of this study was to evaluate the changes in urinary and sexual functioning in patients who undergo abdominal contouring with monsplasty vs non-operated controls. METHODS: A prospective study was performed of patients who underwent abdominal contouring + monsplasty or no surgery...

Millions suffer from chronic vulvar pain (ie, vulvodynia). Vulvodynia represents the intersection of 2 difficult subjects for health care professionals to tackle: sexuality and chronic pain. Those with chronic vulvar pain are often uncomfortable seeking help, and many who do so fail to receive proper diagnoses. The current research developed a multidimensional assessment questionnaire, the Vulvar Pain Assessment Questionnaire (VPAQ) inventory, to assist in the assessment and diagnosis of those with vulvar pain...

17β-estradiol is a potent sex hormone synthesized primarily by gonads in females and males that regulates development and function of the reproductive system. Recent studies show that 17β-estradiol is locally synthesized in non-reproductive tissues and regulates a myriad of events, including local inflammatory responses. In this study, we report that mesenteric lymph nodes and Peyer's patches are novel sites of de novo synthesis of 17β-estradiol. These secondary lymphoid organs are located within or close to the gastrointestinal tract, contain leukocytes, and function at the forefront of immune surveillance...

The seed beetle Callosobruchus maculatus is a significant agricultural pest and increasingly studied model of sexual conflict. Males possess genital spines that increase the transfer of seminal fluid proteins (SFPs) into the female body. As SFPs alter female behaviour and physiology, they are likely to modulate reproduction and sexual conflict in this species. Here, we identified SFPs using proteomics combined with a de novo transcriptome. A prior 2D-sodium dodecyl sulphate polyacrylamide gel electrophoresis analysis identified male accessory gland protein spots that were probably transferred to the female at mating...

BACKGROUND: Pelvic organ prolapse (POP) is a major health concern that affects women. Surgeons have increasingly used prosthetic meshes to correct POP. However, the most common used is synthetic mesh, and absorbable mesh is less reported. This research aimed to evaluate the clinical effectiveness of porcine small intestinal submucosa (SIS). METHODS: Consecutive forty POP patients who met the inclusion criteria underwent pelvic reconstruction surgery with SIS between March 2012 and December 2013...

BACKGROUND: Previous studies have shown that personality characteristics affect sexual functioning. The aim of this exploratory study was to assess and describe the relationship between global personality traits and the stereotypical femininity and masculinity levels with the broad aspects of sexual behaviours and attitudes in the group of 97 heterosexual young adult men aged 19-39 and living in Poland. METHODS: The 'Big Five' personality traits were measured with the NEO-FFI questionnaire; stereotypical femininity and masculinity with the Bem sex role inventory (BSRI); sexual disorders with the International index of erectile function (IIEF); socio-epidemiological data, sexual behaviours and attitudes towards sexuality with a self-constructed questionnaire...

Allopregnanolone, a progesterone metabolite, is one of the best characterized neurosteroids. In a dose that mimics serum levels during stress, allopregnanolone inhibits sexual receptivity and ovulation and induces a decrease in luteinizing hormone levels. The aim of this work was to examine the effect of an intracerebroventricular administration of allopregnanolone on ovarian morphophysiology, serum and tissue levels of progesterone and estrogen, and enzymatic activity of 3β-hydroxysteroid dehydrogenase, 20α-hydroxysteroid dehydrogenase and 3α-hydroxysteroid oxido-reductase in the ovary and in the medial basal hypothalamus on the morning of estrus...

Phospholipase C (PLC) is an important phospholipid hydrolase that plays critical roles in various biological processes in eukaryotic cells. To elucidate the functions of PLC in morphogenesis and pathogenesis in Fusarium graminearum, deletion mutants were constructed of all six FgPLC genes identified in this study. Deletion of FgPLC1, but not the other five FgPLC genes, affected hyphal growth and conidiation. The FgPLC1 deletion mutant (Δplc1) also was defective in conidium germination and germ tube growth...

BACKGROUND: Ecological and evolutionary model organisms have provided extensive insight into the ecological triggers, adaptive benefits, and evolution of life-history driven developmental plasticity. Despite this, we still have a poor understanding of the underlying genetic changes that occur during shifts towards different developmental trajectories. The goal of this study is to determine whether we can identify underlying gene expression patterns that can describe the different life-history trajectories individuals follow in response to social cues of competition...

Urban areas, with large and dense populations, offer conditions that favor the emergence and spread of certain infectious diseases. One common feature of urban populations is the existence of large socioeconomic inequalities which are often mirrored by disparities in access to healthcare. Recent empirical evidence suggests that higher levels of socioeconomic inequalities are associated with worsened public health outcomes, including higher rates of sexually transmitted diseases (STD's) and lower life expectancy...

Background and aims Research on sexual addiction flourished during the last decade, promoted by the development of an increased number of online sexual activities. Despite the accumulation of studies, however, evidence collected in clinical samples of treatment-seeking people remains scarce. The aim of this study was to describe the characteristics (socio-demographics, sexual habits, and comorbidities) of self-identified "sexual addicts." Methods The sample was composed of 72 patients who consulted an outpatient treatment center regarding their sexual behaviors...

The functions of dance and music in human evolution are a mystery. Current research on the evolution of music has mainly focused on its melodic attribute which would have evolved alongside (proto-)language. Instead, we propose an alternative conceptual framework which focuses on the co-evolution of rhythm and dance (R&D) as intertwined aspects of a multimodal phenomenon characterized by the unity of action and perception. Reviewing the current literature from this viewpoint we propose the hypothesis that R&D have co-evolved long before other musical attributes and (proto-)language...

INTRODUCTION: Although impaired sexual function is relatively common, not all sexual impairments are associated with distress. To date, most studies on protective and risk factors for sexual distress have asked about distress in a more general manner and have failed to distinguish different dimensions of sexual distress. AIM: To examine the association of several intra- and interpersonal factors with personal, perceived partner, and interpersonal distress due to an impairment in sexual functioning in women...

INTRODUCTION: Genitalia are linked to self-esteem and male sexual identity, especially among young men, who sometimes require a surgical procedure to acquire more confidence. Among the surgical procedures requested for aesthetical purposes, circumcision is one of the most popular. Although it can be considered to be a simple surgical practice, it may cause severe complications such as penile skin necrosis. PRESENTATION OF CASE: We report a case of a catastrophic situation after a circumcision performed on a 27-year-old HIV positive man resulted in a drastic reduction in the length of the penile shaft due to extensive skin loss; this was subsequently restored using dartos-fascio-myo-cutaneous flaps...
