This longitudinal study explored how sexual well-being changed over time among cohabiting Israeli adults during the 2023 Israel–Hamas War, focusing on sexual function problems, sexual distress, and sexual satisfaction. Using data from 921 participants collected at three time points, before the war (retrospectively), one month into the conflict, and five months later, the study identified significant changes in sexual well-being, shaped by gender and acute stress symptoms. Linear mixed model analyses showed that sexual function worsened early in the war, with partial improvement by the later stage, while sexual satisfaction dropped initially but returned to baseline levels. Sexual distress remained relatively stable across all time points. Gender significantly moderated these patterns, with women showing greater vulnerability to stress-related sexual disruptions than men. Acute stress symptoms also emerged as a key moderator: individuals with higher stress levels experienced more pronounced declines and slower recovery in sexual functioning and satisfaction. However, there was no significant three-way interaction between time, gender, and stress. These findings emphasize that war-related stress has substantial, but varied, impacts on sexual health, highlighting the importance of considering individual differences in gender and stress response when addressing sexual well-being during crises. The results also underscore the partial resilience of the population, with some recovery over time despite persistent challenges. This research contributes to a limited but growing body of the literature on civilian sexual well-being during wartime, offering valuable implications for clinical care, public health planning, and future research targeting sexual and psychological support in conflict settings.

Reports on whether social support and fertility stress moderate the association between quality of reproductive life and semen quality are limited. This study explored the relationship between quality of reproductive life and semen quality, focusing on the moderating roles of social support and fertility stress. This case–control study involved 1024 adult males who attended our institution’s Reproductive Medicine Centre. Participants were categorized into the abnormal (n = 467) and normal semen groups (n = 557) based on World Health Organization standards. Data on quality of reproductive life, social support, and fertility stress were collected via questionnaires, and semen quality parameters were assessed. Relationships and moderating effects were evaluated using nonparametric tests and grouped linear regression models. In the abnormal semen group, quality of reproductive life positively correlated with sperm concentration, total sperm count, sperm progressive motility, and sperm total motility. Quality of reproductive life positively and negatively correlated with social support and fertility stress, respectively. Social support positively influenced sperm total motility, whereas no similar results were found in the normal semen group. In the abnormal semen group, low fertility stress improved the relationship between quality of reproductive life and sperm total motility; however; such significance was not found in the control group. In conclusion, quality of reproductive life is positively associated with semen quality and social support but negatively correlated with fertility stress. Enhancing social support and reducing stress is critical for improving the quality of reproductive life and semen quality, particularly in men with abnormal semen parameters.

No study to date has examined the norms conveyed when condoms are depicted in online pornography. This gap is critical given the popularity of such content and growing evidence that adolescents and young adults turn to pornography for sexual information. Guided by the ₃AM model, three coders analyzed 101 condom-tagged videos from popular websites, each with at least 2 million views. Using CDC guidelines, correct condom use was assessed and found that none of the videos demonstrated all seven recommended steps. Condoms were not used for STI prevention during oral or penetrative sex. Consent for condom removal was often nonverbal and more commonly initiated by the partner being penetrated. However, when the penetrator removed the condom, consent was obtained only half the time, suggesting that violations of informed consent may be normalized. While condoms were present, they were often depicted in ways that diminished their purpose–such as being removed mid-act or portrayed as undesirable–frequently tied to storylines emphasizing taboo or risk. These findings contribute to the literature by illustrating how condom use is represented in widely viewed pornography and identifying clear targets for intervention. Sexual health programs should address condom-related narratives and misinformation conveyed in popular pornography, emphasizing media literacy and safer sex communication.

Sexual aggression is a widespread problem that despite increased prevention efforts remains highly prevalent. Although research has focused on a myriad of predictors of sexual aggression perpetration, basic sexual processes, related to sexual motivation and response, have as yet not been studied extensively. The current study examined the value of combining factors from two theoretical models that have been associated with sexual aggression perpetration, the confluence model and the dual control model of sexual response. A total of 619 heterosexual men (M age = 22.50 years, SD = 3.40) completed a series of questionnaires assessing hostile masculinity, impersonal sex, sexual excitation (SES), sexual inhibition (SIS1, SIS2), and men’s history of using different types of sexually coercive strategies. Negative binomial regressions were used to estimate the predictive value of confluence model and dual control model factors and to test relevant interactions and mediation effects. Results support the confluence model and revealed a role for SES and SIS1, the latter in interaction with hostile masculinity. Moreover, exploratory analyses revealed that the importance of and interplay among predictors varies with type of strategy, pointing at the need for more differentiation between sexually aggressive strategies in future research.

There is growing scientific interest in understanding the psychological and biological mechanisms underlying preferences for BDSM (Bondage/Discipline, Dominance/Submission, and Sadism/Masochism). However, little research has assessed the influence of perceived parenting styles on healthy sexual interests and behavior and how early-life experiences relate to adult BDSM interests. In the current study, we focus on the possible influence of experienced parenting style, perceived interparental dynamics, and childhood traumatic experience on BDSM interest. A cross–sectional survey was conducted by use of an online questionnaire in BDSM-interested individuals (n = 263; 51% cis-women, 46% cis-men, 3% other) and non-BDSM controls (n = 300; 50% cis-women, 50% cis-men). The questionnaire included the Parental Acceptance and Rejection Questionnaire-short form, an adapted Dutch Relationship Questionnaire, and self-developed questions assessing traumatic childhood events. BDSM participants reported more often authoritarian parenting styles, characterized by high parental control and low levels of warmth and affection. Interparental relationship differed significantly, mainly driven by lower interparental independence in families of BDSM individuals. Physical (11% versus 6%) and emotional abuse (18% versus 12%) were also more common among BDSM participants. These findings suggest that the BDSM group perceived more controlling parenting styles and unequal parental power dynamics compared to individuals in the control group. They also reported more physical and emotional abuse than did controls, while reports on sexual abuse and neglect were very low in both groups. Future research is needed to confirm or nuance the causality of these associations, ultimately contributing to BDSM destigmatization.

Prior research has shown that women tend to be more responsive to infant cues than men. However, the influence of different aspects of social gender, like gender norms associated with femininity and masculinity, on individual responses to infant cues, has received no attention to date. This study is the first to investigate how gender roles, conceptualized as continuous traits of femininity and masculinity, are associated with electrophysiological responses to facial stimuli from infants and adults. Electroencephalography was used to record the neural activity of 60 nonparent adults (50% women) while they completed an emotion recognition task displaying infant and adult faces expressing happy, neutral, or sad emotions. Participants also completed an Italian translation of the Bem Sex Role Inventory to assess levels of femininity and masculinity. Results showed that higher levels of femininity were statistically significantly associated with a larger N170 amplitude in response to infant faces. This finding indicates that individuals who adhere more to sociocultural roles associated with femininity exhibit enhanced perceptual processing of infant faces at a very early stage. Our evidence underscores the potential contribution of cultural norms associated with gender to infant cue processing and highlights the need to consider different aspects of social gender in research in this area.

According to national statistics, young men who have sex with men (YMSM) are at disproportionately higher risk for HIV infection in Taiwan, compared with older age groups, women, and heterosexual men. To improve HIV sexual health care, oral rapid self-testing for HIV (ORST) was recently introduced and became available in Taiwan on a limited scale. However, little is known about YMSM’s intention to use ORST, and whether and how YMSM with different HIV testing experiences differ in their ORST intention. Accordingly, an anonymous online survey was conducted among YMSM in Taiwan (N = 2,063). Building upon the theory of planned behavior (TPB) and employing exploratory factor analysis, this study revealed a novel six-factor structure within the expanded TPB framework, highlighting ORST as a unique facilitating condition. Multivariate logistic regression was performed to examine the associations of TPB factors and items with ORST intention among HIV never-testers and ever-testers, demonstrating that significant TPB factors and items varied by HIV testing experience. Significant positive interactions were also identified among ORST ever-users (AORs = 2.10–2.45). HIV never-testers were more likely to report greater ORST intention when perceiving high control under such conditions as ORST not affecting their work/school schedule (AOR = 1.50) and wanting to have condomless anal sex (AOR = 1.60). HIV ever-testers were more likely to report greater ORST intention when holding positive attitudes toward ORST helping to avoid disclosing their HIV status (AOR = 1.38) and perceiving high control regarding ordering ORST kits online anonymously (AOR = 1.37). These findings provide insights that may guide future HIV sexual health-care initiatives tailored according to HIV testing experience for optimal effectiveness.
