High-intensity interval training (HIIT) and slow breathing interventions alleviate premature ejaculation (PE) symptoms.

Background: Physical exercise may alleviate premature ejaculation symptoms, a prevalent male sexual dysfunction linked to a series of negative outcomes for men and their partners. Objective: We investigated the effectiveness of high-intensity interval training (HIIT) and slow breathing interventions on premature ejaculation symptoms and their relation to autonomic activity and attention regulation. Method: Chinese adult men (N = 76, M = 21.89, SD = 3.32) with premature ejaculation completed one of the two-week interventions in their homes or as participants in a normal breathing control group; they reported their age, height, weight, physical activity level, premature ejaculation symptoms, and attention regulation. In the HIIT group, 26 participants engaged in a 7-minute HIIT each day. In the slow breathing group, 25 participants performed 7-minute slow breathing exercises per day while the 25 participants in the normal breathing group similarly performed normal breathing exercises. All participants measured their heart rate once before and five times (with one-minute intervals) after the intervention. When participants had penile-vaginal sex with their partners, they measured their heart rate once after ejaculation. Results: Time × Intervention interaction was significant with lower levels of premature ejaculation symptoms on Days 12, 13, and 14 in the HIIT group (M ± SD = 16.19 ± 3.45, 15.96 ± 3.43, and 15.15 ± 3.62) compared to the normal breathing group (M ± SD = 17.68 ± 3.06, 17.68 ± 3.15, and 17.44 ± 3.25). Higher levels of attention regulation were associated with fewer premature ejaculation symptoms. We also found that a larger increase in heart rate from resting to after sex was associated with fewer premature ejaculation symptoms. Conclusion: Compared to the control group, the efficacy of two weeks of HIIT exercise in mitigating PE symptoms suggests its potential as a novel treatment for PE.

A 2-week high-intensity interval training intervention improves ejaculation control among men with premature ejaculation.

BACKGROUND: Premature ejaculation (PE), which leads to substantial distress in men and their partners, is a common male sexual dysfunction worldwide. However, there is still a lack of effective treatments without side effects. OBJECTIVES: We investigated the effect of high-intensity interval training (HIIT) on PE symptoms. MATERIALS AND METHODS: We recruited 92 Chinese men aged 18-36 to complete the experiment. There were 22 (13 in the control group; 9 in the HIIT group) men diagnosed with PE and 70 (41 in the control group; 29 in the HIIT group) men with normal ejaculatory function. In the HIIT group, participants completed HIIT exercises every morning for 14 days. Participants also completed surveys inquiring about demographic information, erectile function, PE symptoms, body image (including sexual body image), physical activity, and sexual desire. The heart rate was measured before and after each HIIT. In the control group, participants were instructed not to do HIIT, but other procedures were the same as in the HIIT group. RESULTS: Results indicated that the HIIT intervention alleviated PE symptoms in men with PE. In addition, in the HIIT group, men with PE who had a higher heart-rate increase during the HIIT intervention reported the greatest overall decrements in PE symptoms. In men with normal ejaculatory function, HIIT did not decrease PE symptoms. In addition, increments in the heart rate during the intervention were associated with more pronounced PE symptoms post-intervention in this group. Analyses of secondary outcome measures suggested that the HIIT intervention improved general and sexual body image satisfaction of men with PE compared to before the intervention. DISCUSSION AND CONCLUSION: In summary, HIIT intervention may reduce PE symptoms in men with PE. The heart-rate increase during the intervention may be a key factor influencing the effect of the HIIT intervention on PE symptoms.

Bidirectional relationship between sexual arousal and (sex-related) disgust.

Sexual stimuli provoke both sexual arousal and disgust, and the coaction between these emotions determines sexually behavioral outcomes. The current research includes two experiments to explore the bidirectional relationship between sexual arousal toward erotic stimuli and disgust induced by sexual body fluids. Study 1 presented 234 participants (117 women) with sexual body (vs. neutral) fluids followed by erotic stimuli, and Study 2 presented 235 participants (117 women) with erotic (vs. neutral) videos followed by sexual body fluids (and a non-sex-related stimulus). Study 1 showed that exposure to sexual body fluids reduced sexual arousal and the likelihood of sexual engagement toward erotic stimuli in participants with high sexual disgust sensitivity but increased sexual arousal and the likelihood of sexual engagement in participants with low sexual disgust sensitivity, while Study 2 suggested that men exposed to erotic (vs. neutral) stimuli reported lower disgust, stronger sexual arousal state, and higher willingness to interact with the sexual body fluids. There was no relationship between subjective feelings of sexual arousal and disgust in these experiments, while the balance of sexual arousal and disgust toward sexual body fluids and erotic stimuli had a positive association. Also, exposure to erotic stimuli had no effect on reactions to generally disgusting stimulus, but feelings of sexual arousal toward erotic stimuli were positively associated with disgust induced by generally disgusting fluid. These findings suggest that Behavior Immune System regulates disgust to establish a balance between benefit and cost related to sex as well as provide insight into the process underlying sexual dysfunctions.

Effects of Ginger on Disgust, Sexual Arousal, and Sexual Engagement: A Placebo-Controlled Experiment.

Sexual problems are common complaints across countries and cultures, and behavioral immune system theory suggests disgust plays an essential role in sexual functioning. The current study investigated 1) if disgust induced by sexual body fluids would reduce sexual arousal, reduce the likelihood of sexual engagement, and enhance disgust toward subsequent erotic stimuli, and 2) if the administration of ginger would affect these reactions. We administered either ginger or placebo pills to a sample of 247 participants (Mage = 21.59, SD = 2.52; 122 women) and asked them to complete either behavioral approach tasks with sexual body fluids or with neutral fluids. Next, participants viewed and responded to questions concerning erotic stimuli (nude and seminude pictures of opposite-sex models). As expected, the sexual body fluids tasks induced disgust. The elevated disgust induced by sexual body fluids tasks resulted in lower sexual arousal in women, whereas ginger consumption counteracted this inhibiting effect of disgust on sexual arousal. Disgust elicited by sexual body fluids also increased disgust toward the subsequent erotic stimuli. Ginger increased sexual arousal toward the erotic stimuli in both men and women who had completed the neutral fluids tasks. Findings provide further evidence of the role of disgust in sexual problems, and, importantly, that ginger may improve the sexual function of individuals via its sexual arousal-enhancing effect.

Stressors Based on Sexual Orientation and Mental Health Among Lesbian, Gay, and Bisexual Individuals in China: Minority Stress and Perceived Pressure to Get Married.

Chinese Confucian filial piety posits that getting married and having children to maintain family bloodlines is a fundamental duty of children to their parents. Chinese lesbian, gay, and bisexual (LGB) individuals experience added stresses because of the pressure to get married from parents, social environments, and themselves. However, no research thus far has examined the influence of this added stressor, called "pressure to get married," on the mental health of LGB individuals in China. This study examined the influence of sexual orientation-based stresses (i.e., LGB minority stress and perceived pressure to get married) on mental health among 543 Chinese single LGB individuals (259 gay men, 161 lesbians, 68 bisexual men, and 55 bisexual women). We developed a new measure of stress based on perceived pressure to get married and found three factors based on pressure sources: social pressure, parental pressure, and internalized pressure. Both minority stress and perceived pressure to get married were associated with worse mental health. Minority stress and perceived external pressure (i.e., perceived social and parental pressure) were found to be components of a second-order latent variable, called sexual orientation-based stress, which was associated with worse mental health. Sexual orientation-based stress is associated with mental health through coping/emotion and cognitive, but not social, processes. The results indicate that the pressure to get married experienced by Chinese LGB individuals need to be examined further. The findings indicated that the perceived pressure to get married was another significant stressor based on sexual orientation and minority stress, and was associated with mental health among Chinese LGB individuals.

Relationship Status and Marital Intention Among Chinese Gay Men and Lesbians: The Influences of Minority Stress and Culture-Specific Stress.

Marriage and offspring play an essential role in mainland China, and most sexual minorities face enormous pressure to get married because of traditional culture. In Chinese Confucian culture society, gay men and lesbians experience culture-specific stress due to the conflict between same-sex attraction and conventional notions of filial piety and the morality perception of getting married. This study explored how minority stress and traditional culture-specific stress (i.e., perceived filial piety of getting married and the morality perception of mixed-orientation marriage) are related to relationship status and affect the intention to marry among gay men and lesbians in China. Participants (326 gay men and 168 lesbians) completed an online questionnaire that assessed minority stress (i.e., internalized homophobia, self-concealment), perceived filial piety of getting married, the morality perception of mixed-orientation marriage, relationship status, and marital intention. Results indicated that participants with high minority stress, who perceived getting married as filial piety, and who did not perceive mixed-orientation marriage as immoral were more likely to be in an opposite-sex relationship or have a greater intention to marry than were their counterparts. Culture-specific stress had a stronger impact on marital intention for gay participants than for lesbians. Minority stress facilitated the influences of culture-specific stress on marital intention. The findings indicated that both minority stress and culture-specific stress shape the marital intention among Chinese gay men and lesbians, and minority stress has more extensive influences on marital intention than culture-specific stress.

The Influence of Internalized Homophobia on Health-Related Quality of Life and Life Satisfaction Among Gay and Bisexual Men in China.

The aim of this study was to examine the influences of internalized homophobia on Chinese gay and bisexual men's quality of life and life satisfaction. Four hundred and eighty-three participants completed the Internalized Homophobia Scale, Chinese SF-12 Health Survey Version 2, and Satisfaction With Life Scale via the Internet. Scores for quality of life in several domains and life satisfaction were significantly lower than the heterosexuals' norm scores. The present study revealed that internalized homophobia significantly negatively correlated with the mental component summary score and life satisfaction. The mental component summary score mediated the relationship between internalized homophobia and life satisfaction. Sexual orientation moderated the relationship between internalized homophobia and mental component score. Gay and bisexual men in China experience poorer quality of life and less satisfaction with life compared to heterosexuals, and internalized homophobia contributes to both.

Butch-Femme Identity and Visuospatial Performance Among Lesbian and Bisexual Women in China.

Lesbian and bisexual women who self-identify as "butch" show a masculine profile with regard to gender roles, gender nonconformity, and systemizing cognitive style, whereas lesbian and bisexual women who self-identify as "femme" show a corresponding feminine profile and those who self-identify as "androgynes" show an intermediate profile. This study examined the association between butch or femme lesbian or bisexual identity and visuospatial ability among 323 lesbian and bisexual women, compared to heterosexual women (n = 207) and men (n = 125), from multiple cities in China. Visuospatial ability was assessed using a Shepard and Metzler-type mental rotation task and Judgment of Line Angle and Position (JLAP) test on the Internet. Heterosexual men outperformed heterosexual women on both mental rotation and JLAP tasks. Lesbian and bisexual women outperformed heterosexual women on mental rotation, but not on JLAP. There were significant differences in mental rotation performance among women, with butch- and androgyne-identified lesbian/bisexual women outperforming femme-identified and heterosexual women. There were also significant differences in JLAP performance among women, with butch- and androgyne-identified lesbian/bisexual women and heterosexual women outperforming femme-identified lesbian/bisexual women. The butch-femme differences in visuospatial ability indicated an association between cognitive ability and butch-femme identity and suggest that neurobiological underpinnings may contribute to butch-femme identity although alternative explanations exist.
