Sexual attraction

Men who have sex with men (MSM) is an inclusive term used to refer to phenotypic males who have insertive or receptive sex (penile-anal or penile-oral) with other phenotypic males, including people who are transgender or have other gender identities. MSM may report their sexual orientation as homosexual, bisexual, heterosexual, or something else, but this stated sexual orientation may not align with their sexual attraction or behaviors. Several health conditions disproportionately affect MSM compared with age-matched heterosexual men, including HIV infection, anal cancer, syphilis, and depression...

BACKGROUND AND AIMS: Elevation is a major factor shaping plant populations on a global scale. At the same time, reproductive traits play a major role in plant fitness. With increasing altitude and increasingly harsh conditions, decreases in pollinator visitation rates, sexual investment, seed set, and heterozygosity (due to increased selfing) are expected. In response, selection and/or phenotypic plasticity could lead to an increase in plants' floral displays to increase their attractiveness to pollinators and compensates for the negative fitness impacts of reduced pollinator activity...

The natural occurrence, distribution (within a plant) and roles of four phenylbutanoid compounds (anisyl acetone, cue-lure, raspberry ketone and zingerone) are elucidated for the Asia-Pacific and Oceania regions. These phenylbutanoids may act individually or in combination to attract true fruit fly males belonging to a tribe Dacini of subfamily Dacinae (Diptera: Tepritidae). Of special interest are the mutualistic interactions between the Dacini fruit fly males and the tropical daciniphilous (attracting exclusively Dacini fruit flies) orchids - leading to cross pollination for the orchids and enchanced mating success for the flies...

BACKGROUND: Lobar pneumonia caused by Mycoplasma pneumoniae is a relatively difficult-to-treat pneumonia in children. The time of radiographic resolution after treatment is variable, a long recovery time can result in several negative effects, and it has attracted our attention. Therefore, exploring factors associated with delayed radiographic resolution will help to identify these children at an early stage and prepare for early intervention. METHODS: The data of 339 children with lobar pneumonia caused by Mycoplasma pneumoniae were collected from the Department of Pediatrics of Fu Yang People's Hospital, China from January 2021 to June 2022...

Many women experience sexual side effects, such as decreased libido, when taking hormonal contraceptives (HCs). However, little is known about the extent to which libido recovers after discontinuing HCs, nor about the timeframe in which recovery is expected to occur. Given that HCs suppress the activities of multiple endogenous hormones that regulate both the ovulatory cycle and women's sexual function, resumption of cycles should predict libido recovery. Here, using a combination of repeated and retrospective measures, we examined changes in sexual desire and partner attraction (among partnered women) across a three-month period in a sample of Natural Cycles users (Survey 1: n = 1596; Survey 2: n = 550) who recently discontinued HCs...

INTRODUCTION: Uptake of voluntary medical male circumcision (VMMC) remains a challenge in many settings. Innovative implementation strategies are required to scale-up VMMC uptake. METHODOLOGY: RITe was a multi-faceted intervention comprising transport reimbursement (R), intensified health education (IHE) and SMS/Telephone tracing (Te), which increased the uptake of VMMC among uncircumcised men with sexually transmitted infections (STIs) in Malawi. Using a concurrent exploratory mixed-method approach, we assessed the intervention's acceptability, feasibility and appropriateness among men with STIs and healthcare workers (HCWs) at Bwaila District Hospital...

Erectile dysfunction (ED) is one of the most common male sexual dysfunctions and is related to many pathogenic factors. However, first-line treatment, represented by phosphodiesterase 5 inhibitors, is unable to maintain long-term efficacy. Extracellular vesicles (EVs) have recently attracted the attention of researchers in the fields of cardiovascular disease, neurologic disease, and regenerative medicine and may become a treatment for ED. This article reviews recent applications of EVs in the treatment of ED from the aspects of the source, the therapeutic mechanism, and the strategies to enhance therapeutic efficacy...

The stigma associated with sexual victimization (SV) can add to the psychological burden on survivors. We compared experiences of SV and SV stigma by survivor gender and sexuality and evaluated the relevance of public and internalized sources of this stigma to their psychological functioning. An online survey containing measures of SV type (sexual harassment and assault), public SV stigma, internalized SV stigma (self-blame, self-shame, anticipated-shame), and psychological functioning (depression, anxiety, stress, and post-traumatic stress disorder [PTSD] symptomatology) was completed by 877 women and 211 men aged 18 to 66 years ( M  = 30...

In recent years, the expanding roles of anti-Müllerian hormone (AMH) in various aspects of reproductive health have attracted significant attention. Initially recognized for its classical role in male sexual differentiation, AMH is produced postnatally by the Sertoli cells in the male testes and by the granulosa cells in the female ovaries. Traditionally, it was believed to primarily influence gonadal development and function. However, research over the last decade has unveiled novel actions of AMH beyond the gonads, specifically all along the hypothalamic-pituitary-gonadal axis...

ETHNOPHARMACOLOGICAL RELEVANCE: Phoenix dactylifera L. pollen is the male reproductive dust of palm flowers known as a natural product that is considered a strong stimulant of sexual potency and fertility in Iranian traditional medicine (ITM). In this regard, no evidence-based medications are empirically prescribed to treat IMI. However, applying traditional medicine for the treatment of male infertility has attracted more attention in recent years. AIM OF THE STUDY: Phoenix dactylifera L...

OBJECTIVE: To explore what aromanticism is, common misconceptions about this identity, and the experiences people have connecting with an aromantic identity. METHODS: An online, international open-ended survey with a convenience sample of aromantic individuals ( N  = 1642) analyzed with thematic analysis. RESULTS: To identify as aromantic involves a spectrum of experiences with romance commonly tied to experiencing stigma. Connecting with an aromantic identity allows for a greater understanding of the self and a connection to a community...

BACKGROUND: The odours of different body parts and structures, such as external genitalia, female urine, ventral tail radix, infraorbital sinus and interdigital sinus, have a strong attractiveness for rams. The sinus interdigitalis is considered an important trail gland for sexual behaviour, as its odour is included in the list of strongly attractive structures for male animals during the breeding season, being important in pheromone production. OBJECTIVES: In the present study, the effects of sex and breeding season on the morphological and histological structure of the interdigital gland were investigated in Hamdani crossbred sheep (Ovis aries)...

A recent review of cultural and academic discourse presented evidence that some people experience attraction to two (or more) people in a preexisting relationship. This phenomenon, symbiosexuality, is understudied in the field of sexuality. Lack of recognition and validation for this attraction, including in the polyamorous community, may be negatively impacting those who experience symbiosexual attraction. I conducted an integrated mixed-methods analysis of secondary data from the 2023 The Pleasure Study to learn more about symbiosexual attraction...

Purpose: This study aimed to explore the experiences of young adult cancer patients within the Tunisian context. Methods: A total of 104 patients between the ages of 20 and 40, undergoing treatment for various types and stages of cancer, participated in a questionnaire-based survey. The survey encompassed topics related to the socioeconomic and psychological impacts of cancer, coping mechanisms, relationships, sexuality, and future aspirations. Results: Of the participants, 78 were women (75%) and 26 were men (25%), with an average age of 33 years...

Stigma-related stressors are central to understanding psychopathology, distress, and coping in stigmatized groups; individuals who experience attractions to children are a highly stigmatized group. Currently, few validated self-report measures exist to assess stigma-related stressors in minor attracted people (MAPs) and the current research describes the development and initial validation of two measures of internalized stigma and experiences of discrimination. A sample of MAPs (n = 289; mean age = 31...

Despite strong consensus about the basic features that make someone look objectively attractive, contextual variation may modulate subjective assessments. Here, we investigate how social group membership provides such a context, comparing attractiveness judgments between lesbian, gay, and bisexual (LGB) versus straight perceivers, and examining how these attractiveness judgments relate to beliefs about the target person's sexual orientation. We indeed find that perceivers rate targets as more attractive when they believe the target's sexual majority/minority status matches their own (Study 1)...

Viability indicator traits are expected to be integrated extensively across the genome yet sex-limited to ensure that any benefits are sexually concordant. Understanding how such expectations are accommodated requires elucidating the quantitative genetic architecture of candidate traits in and across the sexes. Here we applied an animal modelling approach to partition the autosomal, allosomal, and direct maternal bases of variation in sexual versus non-sexual dorsal wing colouration in the butterfly Eurema hecabe...

Voices can convey content, emotion, and essential information about an individual's gender and social information. Closely related to gender identification and sexual attraction, voices also positively affect many psychological factors of individuals. Surgeries have evolved from treating congenital diseases to fulfilling an individual's aesthetic needs for voice. Voice shaping is emerging as the next cosmetic surgery hotspot after skincare and appearance and body shaping. This paper summarizes the development of voice pitch shaping and genderization procedures out of the cosmetic need...

BACKGROUND: In recent years, Raoultella ornithinolytica (R. ornithinolytica) have attracted clinical attention as a new type of pathogen. A wide range of infections with these germs is reported, and commonly found in urinary tract infections, respiratory infections, and bacteremia. CASE PRESENTATION: We report the case of an elderly woman with liver abscess, choledocholithiasis and cholangitis, who developed gastric fistula and abdominal abscess after underwent choledocholithotomy, and R...

Physiological synchrony (PS) refers to the coordination of bodily responses in close relationships. It seems to be linked to relational well-being, satisfaction, closeness, and empathy. Recent research extends these findings to sexual relationships as well, with evidence suggesting that PS may predict attraction and sexual satisfaction. The current study focuses on PS during sexual activity within established couples. Results suggest that PS develops during sexual activity, in certain contexts, and tends to be greater in magnitude during sexual encounters than during non-sexual interactions...
