Recognition of sex pheromones released by heterosexual moths via sex pheromone receptors is key for establishing mating connections in moths. The day-flying moth Phauda flammans is an oligophagous pest in southern cities of China and Southeast Asian countries. Our previous study reported that male P. flammans can be attracted to two sex pheromone compounds [Z-9-hexadecenal and (Z, Z, Z)-9,12,15-octadecadienal] released by females in the field; however, the mechanism of olfactory recognition is not clear. In this study, two sex pheromone receptor genes (PflaOR29 and PflaOR44) were cloned. Among the different tissues, both PflaOR29 and PflaOR44 were highly expressed in the antennae of mated male adults. At different developmental stages, the expression levels of PflaOR29 and PflaOR44 were significantly greater in mated male adults than other stages. The fluorescence signals of PflaOR29 and PflaOR44 were mostly distributed on the dorsal side of the antennae, with a large number of trichoid sensilla. The results of the gene function of PflaOR29 and PflaOR44 based on a Drosophila empty neuron heterologous expression system indicated that PflaOR29 strongly responded to (Z, Z, Z)-9,12,15-octadecadienal but not to Z-9-hexadecenal, whereas PflaOR44 did not respond to the two sex pheromones. Our findings clarify the sex pheromone receptor gene corresponding to (Z, Z, Z)-9,12,15-octadecatrienal. These results provide essential information for analyzing the mechanism of sexual communication in diurnal moths and for identifying target genes for the development of efficient attractants.

UNASSIGNED: The aim of this study was to investigate sexual communication as a mechanism involved in the link between emotion regulation and sexual functioning in a sample of adult women, also testing the moderating role of relationship status and age in this association.
UNASSIGNED: 1344 sexually active cisgender women (aged 18-57, M = 27.34; SD= 6.484) were recruited from March 30, 2021, to April 12, 2021, through an online survey. From the initial sample, 1280 women were retained and included in the analysis. Participants were asked to respond to three self-report questionnaires: the Difficulties in Emotion Regulation Scale (DERS), the Communication subscale of the Sexual Satisfaction Scale for Women (SSS-W), and the Female Sexual Function Index (FSFI).
UNASSIGNED: We found that sexual communication mediated the link between emotion regulation abilities and female sexual functioning. Moreover, we found that age, but not relationship status, moderated the association between emotion regulation and sexual communication, so that older women with difficulties in emotion regulation processes showed worse sexual communication abilities as compared to younger women.
UNASSIGNED: According to this study\'s results, clinicians and sexual therapists should carefully consider emotion regulation abilities and sexual communication as crucial factors in promoting women\'s sexual well-being.

BACKGROUND: Cervical cancer (CC) and its treatments impact various dimensions of quality of life (QoL), including physical, psychological, and sexual functioning. Sexual health, a crucial QoL aspect, is often compromised, highlighting the necessity for open sexual communication.
METHODS: This study involved 60 women diagnosed with stage IIb-IIIa CC. The 36-Item Short Form Survey (SF-36) was used to measure physical and psychological components of QoL, the Female Sexual Function Index-6 (FSFI-6) to assess its sexual component, and the Sexual Communication Self-Efficacy Scale (SCSES) to diagnose communication confidence. Self-administered questions gauged patient-provider sexual communication. The results include quotes from participants, providing additional insight.
RESULTS: Sexual communication self-efficacy and patient-provider communication correlated significantly with QoL components. Only 23.33% discussed sexual issues with their doctors. Participants\' experiences highlighted the impact of cancer on sexuality and the need for tailored support.
CONCLUSIONS: Post-diagnosis psychosexual changes emphasize the importance of communication in renegotiating sexual identity and needs. Effective communication is associated with improved QoL, highlighting the role of healthcare professionals in addressing psychosexual issues. Integrating PLISSIT and BETTER models provides a comprehensive approach to sexual communication in the cancer context.
CONCLUSIONS: The study demonstrates the importance of sexual communication self-efficacy in QoL of CC patients and highlights the need for healthcare professionals to include sexual communication education in cancer care.

Male orchid bees are unique in the animal kingdom for making perfumes that function as sex pheromone. Males collect volatile chemicals from the environment in the neotropical forests, including floral and non-floral sources, creating complex but species-specific blends. Male orchid bees exhibit several adaptations to facilitate perfume collection and storage. When collecting volatile compounds, males apply lipid substances that they secrete from cephalic labial glands onto the fragrant substrate. These lipids help dissolve and retain the volatiles, similar to the process of \'enfleurage\' in the traditional perfume industry. We investigated how the chemical composition of acquired perfume and labial gland secretions varied across the phylogeny of orchid bees, including 65 species in five genera from Central and South America. Perfumes showed rapid evolution as revealed by low overall phylogenetic signal, in agreement with the idea that perfume compounds diverge rapidly and substantially among closely related species due to their role in species recognition. A possible exception were perfumes in the genus Eulaema, clustering closely in chemospace, partly mediated by high proportions of carvone and trans-carvone oxide. Labial gland secretions, in contrast, showed a strong phylogenetic signal at the genus level, with secretions of Eufriesea and Exaerete dominated by fatty acids and Eulaema dominated by saturated acetates of chain lengths 12 to 16 C-atoms. Secretions of the majority of Euglossa were heavily dominated by one unsaturated long chain diacetate, (9Z)-Eicosen-1,20-diyldiacetate. However, we also identified few highly divergent species of Euglossa in four subclades (11 species) that appear to have secondarily replaced the diacetate with other compounds. In comparison with environment-derived perfumes, the evolution of labial gland secretion is much slower, likely constrained by the underlying biochemical pathways, but perhaps influenced by perfume-solvent chemical interactions.

Parental communication about sex is an important aspect of sexual socialization. However, research has primarily focused on sexual communication\'s presence, frequency, or topics, with less research on the specific messages parents communicate. Further, few studies have differentiated between communication received before and after youth initiated sex. Therefore, in this paper, we coded open-ended survey responses to explore the sex-related messages young adults report receiving from their caregiver(s) before they began engaging in sex. As part of a larger study, 381 U.S. young adults (Mage = 21.0 years, SD = 2.0) completed an online survey and responded to an open-ended question about messages their caregiver(s) communicated before they began engaging in sex. Participants identified as cisgender women (62.2%), cisgender men (12.1%), and gender diverse (25.7%), and were primarily lesbian, gay, bisexual, queer, questioning, or otherwise non-heterosexual (LGBQ+; 70.6%) young adults. Through thematic analysis, we identified six themes for caregivers\' sex-related messages: sex-restrictive, safety and consequences, no, negative, sex-positive, and informational messages. In addition, we found that messages varied by young adults\' gender identity and sexual orientation. Our findings suggest that young adults may not receive proper education about healthy sexual relationships and demonstrate the need for interventions with caregivers, as well as sexual health resources for adolescents and young adults, particularly LGBTQ+ youth.

Sexual communication brings numerous relational and sexual benefits. However, individuals often do not communicate sexually with their partners, resulting in the potential for sexual communication discrepancies (SCD). Guided by uncertainty reduction theory, the purpose of this exploratory study was to examine SCD in married relationships. Results of a cross-sectional survey conducted with 398 married individuals revealed a significant relationship between relational uncertainty and SCD, as well as significant associations between SCD and relational and sexual outcomes. The implications of this study are discussed in the context of sexual communication research and clinical settings.

The objective of this systematic review was to summarize the changes in sexual function in cervical cancer survivors. The additional objective was to exhibit the role of sexual communication in adapting to these changes. A systematic search was performed across four electronic databases. Eighteen studies met the inclusion criteria. The most common sexual dysfunction was pain during sexual intercourse, vaginal dryness, decreased level of satisfaction and sexual interest. Some changes in vaginal anatomy and effects on psychosocial functioning were described. We confirmed that sexual communication with healthcare professionals and partners may be essential to help improve sexuality in CC survivors.

College-age students are disproportionately impacted by sexually transmitted infections. Campus programs that reduce sexual violence have received recent investment, are increasingly common, and may offer a platform to increase condom use, but this has not yet been investigated. We explore this novel question through a secondary analysis of a randomized control trial of RealConsent, a web-based, sexual assault program for college women, on three college campuses. By estimating single and multiple-mediator models we examine the relationships between study assignment, the hypothesized mediators: self-efficacy to discuss safer sex, and clarity and assertiveness in sexual communication, and consistent condom use at follow-up. In the single mediator models, self-efficacy for safer sex communication (aOR: 1.11, 95% CI: 1.03-1.19, p = .004), assertiveness in sexual communication (aOR: 1.06, 95% CI: 1.02-1.11, p =.004), and clarity in sexual communication (aOR: 1.03, 95% CI: 1.00-1.05, p = .026) demonstrated significant direct effects on condom use. No statistically significant relationships between RealConsent and the mediators, nor indirect effects were found. In the multimediator model, there were no statistically significant associations identified. Self-efficacy, assertiveness, and clarity in communication about sex may have a positive impact on condom use but we did not find evidence that RealConsent impacted these mediators and thus no mediated effect was identified. Additional research is needed to develop and assess college-based sexual violence prevention programs that include an additional focus on skills specifically related to condom negotiation and use to understand if these widespread programs offer an efficient and effective platform to reduce the impact of sexually transmitted infections (STIs) among this high-risk population.

Refusal communication is a dyadic process, with one person communicating a refusal and another person responding. To enhance our understanding of this process, we surveyed college students to assess their interpretation of their partners\' responses when they declined vaginal-penile sexual activity. In an online survey, participants were prompted to describe their partners\' reactions when participants refused their partner\'s vaginal-penile sex initiation. Through content analysis, three themes were present: (1) partner accepted the refusal, (2) partner experienced negative emotions, (3) partner ignored their refusals. Participants frequently reported their refusals were accepted. Sexual assault prevention initiatives should work to normalize refusal communication.

Sexual communication functions as an important relational process expediating satisfying sexual experiences (Sprecher & Hendrick, 2004). Much of the existing literature on sexual communication concerning sexual pleasure biases verbal communication (Babin, 2012). This study adds to the existing research regarding patterns of communication surrounding sex and during sex through qualitative analysis. Further, this inquiry focused on participants\' full histories, rather than their tendencies within any current relationship. We analyzed 78 qualitative interview transcripts from participants between the ages of 18 and 69. Participants reported a reluctance to communicate anything but pleasure, discomfort, or dislike during sex to avoid discouraging their partners. Though participants reported a perception that communicating pleasure served as encouragement and affirmation to their partners, most preferred to communicate pleasure nonverbally. Some participants reported a tendency to communicate pain or dislike verbally. Some preferred communication about sexual topics only before or after sexual activities. Participants shared that a high level of comfort with their partner increased sexual communication. How sexual partners communicate sex not only affects pleasure but can only affect intimacy between partners and health. This adds to the scant literature on nonverbal communication during sex and some people\'s preference for that style (Blunt-Vinti et al., 2019).
