Background: Motor cortex excitability may represent the neuronal endpoint of motivational processes and was shown to be modulated by both sexual arousal and deceptive behavior.

Aim: This is the first study to investigate the influence of lying and sex in heterosexual women and men based on motor-evoked potentials (MEPs) measured while viewing sexually arousing pictures.

Methods: Sixteen heterosexual couples were shown 360 trials consisting of pictures displaying both almost naked females and males and neutral control images. In a subsequent forced-choice question about wanting to see the respective pictures fully naked, they were instructed to either answer in agreement with or opposite to their sexual preference. Participants went through 2 blocks of answering truthfully and 2 blocks of lying, with these 4 blocks being shown in a randomized alternating order.

Outcomes: To measure cortical excitability, MEPs were used, evoked by single transcranial magnetic stimulation pulses between image presentation and response.

Results: In normalized MEPs, women and men showed higher amplitudes for preferred over non-preferred sexual stimuli, but only on a descriptive level. Planned contrasts showed higher non-normalized MEPs for lying in all picture categories. Direct comparisons to a preliminary study showed overall lower effect sizes.

Clinical implications: Both sexes tend to show higher MEPs in response to their sexually preferred stimuli. MEPs are not stable markers for willful volitionally controlled deception although lying does increase cortical excitability. The present experimental design does not seem valid enough to serve as a diagnostic marker for sexual preference or paraphilia and malingering.

Strengths and limitations: This is the first study investigating whether sexual motivational stimuli modulate MEPs in women, while also examining the influence of lying for both sexes. The sample was too small for some found effects to be significant. Also, the experimental setup may have been less suited for female participants in comparison to male ones.

Conclusion: The operationalization of sexual motivation via MEPs seems to highly depend on different experimental factors including the sex of the participants, induced motivation, and lying.

Background: The ventral and distal aspects of the corpora cavernosa are the thinnest, increasing the likelihood of cylinder extrusion or crossover complications pertaining to inflatable penile prosthesis procedures. A double distal corporal anchoring double stitch can be used to robustly secure impending lateral extrusions and crossovers of implant cylinders. It is a novel, effective corrective measure for the uncommon complication of migrated cylinders in inflatable penile prosthesis placement.

Aim: To describe the surgical indications and technique for the double distal corporal anchoring fixation stitch for lateral penile implant cylinder extrusion.

Methods: We discuss a double-stitch technique that is performed following corporoplasty and capsulotomy. A lateral incision is made subcoronally on the affected side to identify the crossover or lateral extrusion. The cylinder is repositioned properly within the native corpora to prevent further cylinder migration. Two 2-0 Ethibond sutures are threaded through the distal cylinder eyelet, and each suture is delivered through the glans with a Keith needle and tied off. An incision is made in the glans, and 1 arm of each suture is tied with the other to create a bridge between the sutures that can be positioned deep within the skin of the glans.

Outcomes: Over the past 4 years, 66 patients with lateral cylinder extrusion underwent the double distal corporal anchoring fixation stitch procedure, with overall improved satisfaction (97%). Only 2 patients had surgical complications. One patient experienced repeated lateral extrusion of the penile implant cylinders 6 weeks following the double-anchoring stitches procedure. The second patient developed a painful suture granuloma that necessitated excision, which resolved this issue, and the penile implant cylinder remained in the proper position over a year later.

Clinical implications: This technique ensures the secure fixation of the affected cylinders in the surgical capsule by creating a bridge between 2 sutures holding each repositioned cylinder in place, and the ensuing fibrotic reaction helps to fixate the extruded cylinder within the midglandular tissue.

Strength and limitations: This surgical technique describes the double distal corporal anchoring stitch for lateral penile implant cylinder extrusion. Further studies are warranted to validate long-term outcomes and satisfaction.

Conclusion: The double distal corporal anchoring fixation stitch is a safe and efficacious method to secure cylinders in the proper surgical capsule during revision procedures to correct distal crossovers or laterally extruded penile prosthesis implants.

Background: While some individuals engage in recreational pornography use (PU), others may develop an uncontrolled pattern of use termed problematic pornography use (PPU). PPU is characterized by persistent, excessive, or compulsive engagement with pornographic content, despite distress and adverse consequences. Impulsivity has been identified as a factor associated with PU and PPU.

Aim: The present meta-analysis aims to sum up the existing research on the relationship between impulsivity and PU/PPU and investigate whether age and gender could moderate this relationship.

Methods: A keyword-based systematic literature search was performed to identify articles that assessed PU/PPU and impulsivity. Extracted correlations were converted into Fisher's Z. Meta-regression analyses were also performed. Publication bias was assessed by Egger's regression intercept.

Outcomes: Outcomes included general impulsivity and its dimensions (ie, negative and positive urgency, lack of premeditation and perseverance), sensation seeking, PU, and PPU.

Results: Meta-analytic results of the random effects model showed a significant positive correlation between impulsivity as total score and PU (n = 1504, k = 4, Fisher's Z = 0.21, P < .001) and PPU (n = 20174, k = 13, Fisher's Z = 0.17, P < .001). Significant and positive associations were also found between sensation seeking and PU (n = 11707, k = 11, Fisher's Z = 0.14, P < .001) and PPU (n = 20152, k = 9, Fisher's Z = 0.06, P < .001). Concerning the relationship between PPU and different dimensions of impulsivity, almost all the associations were significant and positive. The dimension of positive urgency and attentional and nonplanning impulsivity showed the strongest association. Age (β = -0.50, Q = 101.26, df = 11, P < .001) and gender (female = 1; β = -0.46, Q = 102.54, df = 12, P < .001) moderated the association between general impulsivity and PPU. No risk of publication bias emerged.

Clinical implications: Prevention programs of PPU should focus on impulsivity and certain key dimensions (eg, positive urgency, attentional and nonplanning impulsivity) and be tailored to individual impulsivity profiles, considering age and gender differences.

Strengths and limitations: The primary strength of this meta-analysis is that it considers various conceptualizations of impulsivity. However, the results are to be interpreted with caution since >30% of relevant studies had to be excluded because information could not be gathered from the study authors.

Conclusion: These results suggest that general impulsivity is linked to PU and PPU and that specific dimensions of impulsivity (ie, attentional impulsivity, nonplanning impulsivity, and positive urgency) can serve as risk factors for PPU.

Background: In recent years, there has been growing interest in the use of hyaluronic acid (HA) for the treatment of premature ejaculation (PE). The efficacy of this treatment is quite controversial.

Aim: This study intended to evaluate the efficacy and safety of glans penis augmentation with HA gel for PE.

Methods: This systematic review includes randomized controlled trials (RCTs), primary clinical trials, prospective and retrospective studies, case series, and case reports. Searches in Embase, PubMed, Cochrane, Web of Knowledge, and ClinicalTrials.gov were performed blindly by 2 reviewers.

Outcomes: Intravaginal ejaculation latency time (IELT), questionnaires about PE, glans circumference (millimeters), and adverse events.

Results: Thirteen studies were included in the evaluation: 4 RCTs, 8 prospective observational studies, and 1 restrospective study. The number of patients who received HA gel on the glans penis was 706. According to the results of 2 placebo-controlled RCTs, HA gel treatment significantly improved IELT at the end of the first month (mean difference [MD], 65.44 seconds). In the first month after the HA gel injection procedure, IELT increased vs before the procedure (MD, 176.18 [95% CI, 146.89-205.48]; P < .001, I2 = 83%). When the IELT values ​​were compared at 6 months after HA gel application, IELT improved vs before the procedure (MD, 143.93 [95% CI, 124.78-163.09]; P < .001, I2 = 82). The glans circumference expanded by approximately 1.5 cm after the procedure (MD, 14.82 mm [95% CI, 12.75-16.90]; P < .001, I2 = 65%). When the side effect profile of other studies was examined, side effects were observed in 91 patients after HA gel injection applied to 598 patients (15.22%). Among these side effects, the most common were pain (n = 46, 7.69%), bulla/nodule formation (n = 25, 4.18%), and ecchymosis (n = 20, 3.34%).

Conclusion: While HA shows promise as a therapeutic option for PE, ongoing research is essential to elucidate its clinical utility, mechanisms of action, and comparative efficacy.

Background: Sexual distress (eg, feeling distressed, unhappy, frustrated, stressed, dissatisfied, or bothered about their sexuality) is a central concern reported by patients seeking sex therapy, and might be related to sexual self-esteem and mindfulness disposition, yet research is needed to examine the links among those variables within the specific population of patients seeking therapy.

Aim: This study aimed to examine the indirect role of sexual self-esteem in the relationship between dispositional mindfulness and sexual distress.

Methods: The study was conducted among 696 patients undergoing sexual therapy (mean age 34.19 ± 11.21 years, age range 18-78 years). Participants identified as women (57.3%), men (38.5%), or nonbinary (4.2%). They completed self-report questionnaires assessing dispositional mindfulness (Five Facet Mindfulness Questionnaire), sexual self-esteem (Multidimensional Sexuality Questionnaire), and sexual distress (Sexual Distress Scale-Revised), during their first few sessions (ie, first to third sessions [the assessment phase]).

Outcomes: Sexual distress was the main outcome, as measured with the Sexual Distress Scale-Revised.

Results: Results indicated that 54% (n = 376) of patients reported elevated sexual distress based on the questionnaire threshold score. Path analyses indicated an indirect effect in which higher dispositional mindfulness was associated with higher levels of sexual self-esteem, which in turn was associated with lower sexual distress. Results also highlighted that specific facets of mindfulness were related to higher sexual self-esteem (ie, describing, and nonreacting) and lower sexual distress (ie, nonjudgment and acting with awareness). The integrative model explained 23% of the variance of sexual distress scores.

Clinical implication: Findings suggest that addressing specifically sexual self-esteem and mindfulness may represent relevant clinical avenues to reduce sexual distress among sex therapy patients.

Strengths and limitations: Strengths of this study include the novel examination of the role of sexual self-esteem in the link between mindfulness disposition and sexual distress in a large clinical sample of patients seeking sex therapy. Limitations includes reliance on patient self-report and a cross-sectional design that limit conclusion regarding causality.

Conclusion: This study makes a valuable contribution to the existing body of research highlighting the pivotal roles of sexual self-esteem in the link between dispositional mindfulness and reduced sexual distress among adults undergoing sex therapy, allowing us to identify potential targets of intervention.

Background: Pulmonary arterial hypertension (PAH) can have several consequences on sexual function, which can lead to worsened quality of life.

Aim: The study sought to assess sexual function and its association with health functionality and quality of life in females with PAH.

Methods: A descriptive cross-sectional study was carried out in pulmonary circulation outpatient clinics from January 2022 to March 2023 in females diagnosed with pulmonary hypertension. Assessment was carried out through the application of the Female Sexual Function Index, the 36-item World Health Organization Disability Assessment Schedule, and the Medical Outcome Study 36-Item Short Form Survey.

Outcomes: Data were analyzed using SPSS version 22.0 and JASP, and Spearman's correlation tests were applied between the instruments, with a P value <.05 considered significant.

Results: A total of 91 females were assessed. It was identified that 90.1% of females had sexual dysfunction, with worse scores in females with sexual dysfunction in the domains of satisfaction, arousal, and desire, with average health functionality and quality of life. There were significant correlations between the domains of mobility, getting along, life activities, and the overall functionality score with some domains of sexual function, especially arousal and satisfaction. We found significant correlations between some domains of quality-of-life assessment with the domains of desire, arousal, and satisfaction, and with the overall score of sexual function assessment, as well as strong correlations between health functionality and quality of life.

Clinical implication: The data reinforce the need for rehabilitation programs and social support for this population.

Strengths and limitations: This is one of the few studies to evaluate sexual function, quality of life, and health functionality in women with PAH. Due to limitations in data collection, we were unable to assess certain factors such as hormone levels and a history of sexual abuse.

Conclusion: We identified a high prevalence of sexual dysfunction in females with PAH with mild functional impairment and a moderate quality-of-life score with correlations between sexual function, health functionality, and quality of life.

Background: Pregnancy loss affects 1 in 4 women and is linked with poorer overall health and relationship outcomes. Despite sexual well-being's importance to health, how sexual well-being changes across time after a pregnancy loss and what might predict such changes, like perinatal grief, have never been examined, leaving practitioners and couples without knowledge of what to expect.

Aim: We aimed to examine (1) how sexual satisfaction, sexual desire, sexual distress, and perinatal grief change from 10 to 25 weeks postloss for both couple members; and (2) if perinatal grief levels at 10 weeks postloss predict sexual well-being trajectories.

Methods: Women and gender-diverse individuals who were pregnant when a pregnancy loss occurred (within the last 4 months) and men, women, and gender-diverse partners who were not pregnant (N = 132 couples) independently completed 4 monthly assessments of sexual well-being and perinatal grief.

Outcomes: Outcomes included sexual satisfaction (Global Measure of Sexual Satisfaction), sexual desire (Sexual Desire Inventory), sexual distress (Sexual Distress Scale-Short Form), perinatal grief (Perinatal Grief Scale).

Results: Dyadic growth curve modeling indicated that, from 10 to 25 weeks postloss, both couple members' sexual satisfaction increased, and their sexual desire remained stable; sexual distress decreased for partners but remained stable for individuals who were pregnant; and both couple members' perinatal grief decreased. Perinatal grief levels at 10 weeks postloss did not predict sexual well-being trajectories over time.

Clinical implications: Given sexual well-being's dynamic nature, clinicians should regularly discuss sexuality with both couple members after pregnancy loss. During such discussions, clinicians could reassure couples about their sexual relationship's recovery by sharing that, on average, sexual satisfaction, sexual desire, and sexual distress tend to improve or stay the same (rather than worsen) from 10 to 25 weeks postloss. They can also share that perinatal grief tends to decrease during this time and is unrelated to trajectories of sexual satisfaction, sexual desire, and sexual distress.

Strengths and limitations: This is the first study, to our knowledge, to examine how sexual well-being changes across time after a pregnancy loss and perinatal grief's role in such changes. The results may not generalize broadly, as most couples were in mixed-gender/sex relationships, identified as White, and were relatively affluent.

Conclusion: From 10 to 25 weeks postloss, both couple members tend to experience improvements in their overall sexual well-being and declines in their perinatal grief. Early perinatal grief levels and subsequent sexual well-being trajectories are seemingly unrelated.
