Though local anesthetic can prolong intravaginal ejaculation latency time by reducing penile hypersensitivity, the effect on the hypersensitive and nonsensitive areas of penis is still unclear. Aim The study aimed to explore whether the effect of local anesthetic on the hypersensitive and nonsensitive areas of the penis is different in premature ejaculation. Methods Penile neurophysiological tests were performed on 290 patients with primary premature ejaculation. The sensory threshold, latency, and amplitude were recorded before and after the topical application of a local anesthetic (lidocaine cream) on the penis. Outcomes Local anesthetics increased the sensory thresholds of hypersensitive and nonsensitive areas of the penis without difference but only prolonged the latency of the hypersensitive areas. Results According to the neurophysiological results, 149 of 290 patients with primary premature ejaculation had normal penile sensitivity and 141 had penile hypersensitivity. While penile hypersensitivity does not necessarily mean that the whole penis is hypersensitive, and may be that only a part of the penis is hypersensitive, and we examined the following hypersensitivities: glans hypersensitivity only (14 cases), shaft hypersensitivity only (77 cases), and whole penis hypersensitivity (50 cases). Local anesthetics (lidocaine cream) increased the sensory thresholds of hypersensitive and nonsensitive areas of the penis without difference (P < .001) but only prolonged the latency of the hypersensitive areas (P < .001), and the latency of the nonsensitive areas was not different (P > .05). Clinical Implications The present discovery implies that it is possible to improve ejaculation by applying local anesthetics externally to the hypersensitive areas of the penis to reduce the afferent local sensory signals, and improve intravaginal ejaculation latency time through accurately decreasing penile sensibility. Strengths & Limitations This is the first large-sample study to explore the difference of local anesthetics’ effects on the hypersensitive and nonsensitive areas of the penis by means of neurophysiological methods in premature ejaculation. Our study exclusively examines alterations in penile evoked potential following electrical stimulation, which may not entirely encompass shifts in penile receptivity during sexual activity. Conclusion The effects of local anesthetics on the same penis varied with penile sensitivity, and can only prolong the latency of hypersensitive area of the penis. The effect of local anesthetic on the hypersensitive and nonsensitive areas of the penis is different in premature ejaculation.","PeriodicalId":21782,"journal":{"name":"Sexual Medicine","volume":"124 2","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140778027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Italian women who have sex with women: prevalence and co-occurrence of sexual practices","authors":"Sofia Pavanello Decaro, Rodolfo Pessina, Marco Biella, A. Prunas","doi":"10.1093/sexmed/qfae017","DOIUrl":"https://doi.org/10.1093/sexmed/qfae017","url":null,"abstract":"Abstract Background Sexuality research on the sexual practices of women who have sex with women (WSW) has thus far mostly centered on risk factors and addressed a limited number of practices, with a focus on oral sex and insertive vaginal sex. Aim This study arises from the need to fill such a significant gap, which prevents researchers, clinicians, and policy makers from being adequately up-to-date on the sexual habits and tendencies of this population. Methods A multiple-choice questionnaire was completed by 723 WSW with a mean (SD) age of 29.14 (6.94) years. Outcomes The survey included closed questions on sexual practices, including genital and oral sex, but also nongenital sexual contact (petting and intercrural sex), anal sex, and kinky practices. Results The most common sexual practices were self-masturbation (99.03%), oral sex (performed or received, 98.20%), and insertive genital sex (performed or received, 89.07%). Half of our sample had tried kinky practices at least once in a lifetime (51.31%). Respondents tended to experiment sexually more with stable partners rather than with casual ones. Comparisons among practices in the lesbian and bisexual population are presented. Clinical Implications Providers should be aware that sexual orientations have their own specificities, including sexuality and practices, which should increase their knowledge and comfort in working with sexual minorities. Strengths and Limitations The novel topic of the study addresses the gap in sexuality research among WSW. Strengths include the sex-positive approach, the inclusion of an array of sexual practices, and the consideration of the specificities of the group. Limitations in the generalization of the results are the cross-sectional design and the explicit topic, which may have kept some persons from responding. Conclusion We propose the framing of sex as going beyond genital contact, and we invite clinicians and researchers who come into contact with WSW to be aware that sexual orientation can be associated with specificities regarding sexuality and sexual practices.","PeriodicalId":21782,"journal":{"name":"Sexual Medicine","volume":"55 ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140790748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim To identify the experiences of sex and information needs among Chinese patients with PCa after ADT treatment. Methods This qualitative study included 15 Chinese patients with PCa in urology inpatient wards, selected via a purposive sampling method. Semistructured interviews were conducted face-to-face or by telephone regarding sexual experiences and information needs after ADT treatment. Outcomes Themes and subthemes were assessed among patients with PCa. Results Two themes and 5 subthemes emerged from the interview data. The first theme was “altered sexual life and attitude” with 3 subthemes: (1) undesirable sexual function and altered sexuality, (2) sexual attitudes and sociocultural cognition, and (3) behavior adjustment and intimacy. The second theme was “scarce information sources” with 2 subthemes: (1) uncertainty and lack of information support and (2) barriers to access sexual information. Clinical Implications The present findings suggest that the following may help patients with PCa manage treatment and develop appropriate sexual attitudes: a tailored sexual health education program, well-equipped consultations rooms, and information delivery innovations. Strengths and Limitations Strengths of this study included adding unique evidence among patients with PCa within an Asian context to reveal the understudied topic of sexual health and information needs after ADT treatment. This study was limited in being representative of all Chinese patients with PCa, with different marital statuses, treatment therapies, sexual orientations, and barriers of information seeking. Conclusion Sexual life and attitude among patients with PCa were affected by their sociocultural cognition and ADT treatment, and most patients received insufficient information and sexual health education from health care providers.","PeriodicalId":21782,"journal":{"name":"Sexual Medicine","volume":"81 ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140786508","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, little is known about sexual health in this population. Aim To examine aspects of sexual health among the oldest old and explore its associations with sociodemographic, health-related, and lifestyle factors. Methods We conducted a population-based cross-sectional study including 183 individuals aged ≥85 years who were residents in Stockholm County, Sweden. Responders (response rate, 63%) were interviewed on a range of health, sociodemographic, and lifestyle parameters, including aspects of sexual health. Participants’ responses to the sexual health items were reported as proportions with 95% CIs. Associations were examined with multivariable logistic regression. Outcomes We examined sexual activity, sexual satisfaction, problems related to sexual health, and inquiries on sexual health by a health care provider. Results Twelve percent of participants (95% CI, 8%-17.6%) were sexually active, and 63.9% (95% CI, 56.5%-70.9%) were satisfied with their sexual lives during the past year. A third (35%; 95% CI, 28.4%-42.2%) reported at least a problem related to sexual health. Only 2.2% (95% CI, 0.6%-5.5%) were asked about sexual health by a health care provider, while 8.2% (95% CI, 4.7%-13.2%) identified a need for such an assessment. Yet, 85.2% (95% CI, 79.3%-90.0%) indicated no need for their sexual health to be evaluated by a health care provider. Being partnered was positively associated with sexual activity (adjusted odds ratio, 9.13; 95% CI, 2.53-32.90), whereas having strong social support was positively associated with being satisfied with one’s sexual life (adjusted odds ratio, 2.96; 95% CI, 1.53-5.74). Clinical Implications Health care providers should be proactive in assessing the sexual health of the oldest individuals. Strengths and Limitations A representative sample of an underresearched population was used in this study. However, the generalizability of our findings may be restricted due to the small sample. To maintain statistical power from a relatively small sample, we might have lost explanatory power. Given the observational cross-sectional nature of the data, we cannot draw causal inferences based on the observed associations. Conclusions A 10th of participants were sexually active, and the majority were satisfied with their sexual lives. Although many participants reported problems related to sexual health, few expressed the need to discuss sexual health with health care providers. Future studies should explore potential barriers to addressing sexual health and unmet health care needs among the oldest old.","PeriodicalId":21782,"journal":{"name":"Sexual Medicine","volume":"49 ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140770172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
