Background: Peyronie's disease (PD) is a connective tissue disorder that affects the penis and is characterized by abnormal collagen structure in the penile tunica albuginea, resulting in plaque formation and penile deformity. PD's overall prevalence is estimated at 3.2% to 8.9%, with rates as high as 20.3% among men with type 2 diabetes mellitus (DM). However, the characteristics of DM associated with PD complications remain unclear.

Aim: To explore clinical associations between DM characteristics and PD complications.

Methods: We conducted a retrospective analysis of patients with DM and PD who presented at our institution between 2007 and 2022. We examined patients' clinical histories, DM- and PD-related clinical parameters, and complications. Penile deformities were assessed through physical examination, photographs, and penile Doppler ultrasound. Patients were categorized into subgroups based on age of DM onset: early (<45 years), average (45-65 years), and late (>65 years).

Outcomes: Outcomes included effects of DM characteristics on PD development, progression, and severity.

Results: In total, 197 patients were included in the evaluation. Early-onset diabetes and elevated hemoglobin A1c (HbA1c) levels exhibited significant correlations with the early development of PD (ρ = 0.66, P < .001, and ρ = -0.24, P < .001, respectively). Furthermore, having DM at an early age was associated with the occurrence of penile plaque (ρ = -0.18, P = .03), and there were no significant differences in plaque dimensions (ρ = -0.29, P = .053). A rise in HbA1c levels after the initial PD diagnosis displayed positive correlations with the formation of penile plaque (ρ = 0.22, P < .006).

Clinical implications: These findings emphasize the need for comprehensive assessments and personalized treatment strategies for individuals with DM and PD. Enhanced management approaches can improve outcomes for those facing both challenges.

Strengths and limitations: Limitations include the single-site retrospective design with potential selection bias, inaccuracies in medical record data, and challenges in controlling confounding variables.

Conclusions: This study highlights that early-onset diabetes and poor diabetes control, as indicated by a subsequent rise in HbA1c levels following PD diagnosis, are significantly correlated with the onset and severity of PD. Revealing the mechanisms behind these findings will help us develop better management strategies for individuals with DM and PD.

Background: Genital self-image is among the factors affecting women's sexual function.

Aim: The present study aimed to determine changes in the genital self-image and its relationship with women's sexual function in the third trimester of pregnancy and postpartum.

Methods: The participants of this prospective cohort study included 301 eligible pregnant women chosen through stratified random sampling with proportional allocation from comprehensive health centers in Gorgan, Iran. The Persian version of the 7-item Female Genital Self-Image Scale, the 6-item Female Sexual Function Index, and Depression Anxiety and Stress Scale 21 were filled in a self-report manner on 2 occasions: (1) 30 to 37 weeks of pregnancy and (2) 12 to 16 weeks (± 2 weeks) postpartum. Finally, the data were analyzed using SPSS 24 software.

Outcomes: Outcomes included Female Genital Self-Image Scale and Female Sexual Function Index changes from pregnancy to postpartum according to the childbirth mode.

Results: The mean age of participants was 29.66 ± 5.27 years. These values for the genital self-image scores of women during pregnancy (19.18 ± 3.25) and postpartum (19.43 ± 3.57) were not significantly different (P = .30). Also, this difference was not statistically significant regarding the mode of delivery in 2 groups of women with vaginal birth (P = .62) and cesarean section (P = .14). The mean Female Sexual Function Index scores during pregnancy (15.15 ± 6.73) and postpartum (17.52 ± 6.46) were significantly different (P = .001). In addition, this difference was significant in women with vaginal birth (P = .004) and cesarean section (P = .001).

Clinical implications: Clinicians should inform women/couples about changes in female sexual function and address genital self-image as a factor involved in female sexual function during pregnancy and postpartum.Strengths and Limitations: Because the participants of this study were women in the third trimester of pregnancy, the obtained results may not be generalized to pregnant women in the first and second trimesters of pregnancy or even to different postpartum periods (ie, midterm and long term).

Conclusion: The results showed that the female genital self-image is not significantly different during pregnancy and postpartum, or with the mode of delivery. However, the female sexual function score in postpartum is higher than in pregnancy, regardless of the mode of delivery.

Background: Prior studies primarily of men correlated low personal genital satisfaction (PGS) with decreased sexual activity; however, the association between PGS and genital anatomy perceptions is unknown, and there is a paucity of studies examining women.

Aim: We assessed the relationship between genital satisfaction, survey respondent sexual activity, and perceptions of anatomy and function.

Methods: A 54-item REDCap survey was distributed to any-gendered volunteers ≥18 years of age through ResearchMatch from January to March 2023. Responses were split into (1) high PGS and (2) low PGS. Analysis was performed using chi-square tests on survey responses and a Mann Whitney U test on median satisfaction level.

Outcomes: Outcomes were genital anatomy perceptions, sexual activity, and respondents' PGS.

Results: Of the 649 respondents who started the survey, 560 (86.3%) completed it. Median PGS was 7 of 10, forming subgroups of high (≥7 of 10) satisfaction (n = 317 of 560 [56.6%]) and low (<7 of 10) satisfaction (n = 243 of 560 [43.4%]). The mean age was 45.8 ± 16.8 years, and demographics were notable for 72.1% women (n = 404 of 560), 83.2% White (n = 466 of 560), 47.9% married (n = 268 of 560), and 75.5% bachelor's degree holders (n = 423 of 560). Comparing high- and low-PGS groups, more low-PGS respondents felt normal flaccid penis length to be <2 inches (11.1% vs 5.1%; P = .008). High-PGS respondents more often responded that it is normal for women to have orgasms over half the time (20.8% vs 13.2%; P = .0002) or to identify as being sexually active (81.1% vs 71.6%; P = .008). Women were more likely than men to report larger normal testicle sizes as 60.1 to 90 mL (24.5% vs 10.3%; P < .0001), whereas more men felt that normal testicle size was 7 to 15 mL (26.3% vs 11.4%; P < .0001). Orgasm length perceptions also differed: more women felt female orgasm length was 2.6 to 5 seconds (36.6% vs 16.7%; P < .0001), and more men believed female orgasms to be longer, at 7.6 to 10 seconds (29.5% vs 17.3%; P = .002), 10.1 to 12.5 seconds (11.5% vs 5.2%; P = .0008), and >12.5 seconds (12.2% vs 5.7%; P = .009). Respondents' views on their genitalia differed by gender, with women more likely to feel that their genitals are normal compared with men (89.4% vs 75.0%; P < .0001).

Clinical implications: PGS may be a useful screening tool given its association with sexual activity.

Strengths and limitations: Our large-scale survey assesses public perceptions of genital anatomy and function. Limitations include a lack of gender nonbinary perceptions.

Conclusion: Gender and PGS interact with perceptions of male anatomy and female sexual activity, and the frequency of sexual activity was higher among high-PGS respondents; however, the direction of these interactions remains unclear and requir

Background: Female sexual dysfunction is common in the general population, with age emerging as a significant determinant of sexual activity and functioning.

Aim: To establish age-specific reference scores for the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) in the general Dutch female population.

Methods: A retrospective, cross-sectional, questionnaire-based study was conducted in the Netherlands. The study population comprised 2518 Dutch-speaking women aged ≥18 years, representing a cross section of the general Dutch population. The PISQ-12 was used to assess sexual functioning in heterosexual women. The Groningen Defecation and Fecal Continence questionnaire was utilized to demonstrate demographic factors.

Outcomes: We established age-specific reference scores for the PISQ-12 in the general Dutch population.

Results: Of the 2518 women, 1592 (63.2%) were sexually active and 926 (36.8%) were not. Further analysis focused on the sexually active group: we found a decrease in mean total PISQ scores, ranging from 38.34 among 18- to 34-year-olds to 36.98 among ≥65-year-olds. Older women scored lower in the behavior domain, specifically pertaining to sexual desire (P < .001) and sexual excitement (P < .001). They also had lower scores in the partner-related domain regarding partner problems of erection (P < .001) and orgasm perception (P < .001). With increasing age, negative emotional reaction scores were higher (P < .001). In the physical domain, we observed significantly different scores for pain during sexual intercourse (P < .001) and restrictions in sexual activity due to fear of urinary leakage (P < .001), with the lowest scores in the youngest group.

Clinical implications: These age-specific references scores of the PISQ-12 provide an overview of sexual functioning of a general population, which enables caregivers to assess and interpret patients' individual scores more accurately.

Strengths and limitations: We included only sexually active women in our subanalyses, potentially introducing selection bias for older women with better physical conditions. The study's strength lies in its extensive sample size, representing a cross section of the general Dutch population. Furthermore, the self-administered questionnaire approach helped minimize embarrassment and obtain realistic responses.

Conclusion: Our study demonstrated age-specific PISQ-12 reference scores and highlighted associations between aging and diminishing scores of sexual desire, sexual excitement, erection problems, and orgasm perception, while women aged 18 to 34 years reported the lowest scores for pain during intercourse and limited sexual activity due to fear of urinary leakage.

Background: There are varying reports of immunohistochemically detected prostatic marker protein distribution in glands associated with the female urethra that may be related to tissue integrity at the time of fixation.

Aim: In this study we used tissue derived from rapid autopsies of female patients to determine the distribution of glandular structures expressing prostate-specific antigen (PSA) and prostate-specific acid phosphatase (PSAP) along the female urethra and in surrounding tissues, including the anterior vaginal wall (AVW).

Methods: Tissue blocks from 7 donors that contained the entire urethra and adjacent AVW were analyzed. These tissue samples were fixed within 4-12 hours of death and divided into 5-mm transverse slices that were paraffin embedded. Sections cut from each slice were immunolabeled for PSA or PSAP and a neighboring section was stained with hematoxylin and eosin. The sections were reviewed by light microscopy and analyzed using QuPath software.

Observations: In tissue from all donors, glandular structures expressing PSA and/or PSAP were located within the wall of the urethra and were present along its whole length.

Results: In the proximal half of the urethra from all donors, small glands expressing PSAP, but not PSA, were observed adjacent to the and emptying into the lumen. In the distal half of the urethra from 5 of the 7 donors, tubuloacinar structures lined by a glandular epithelium expressed both PSA and PSAP. In addition, columnar cells at the surface of structures with a multilayered transitional epithelium in the distal half of the urethra from all donors expressed PSAP. No glands expressing PSA or PSAP were found in tissues surrounding the urethra, including the AVW.

Clinical implications: Greater understanding of the distribution of urethral glands expressing prostatic proteins in female patients is important because these glands are reported to contribute to the female sexual response and to urethral pathology, including urethral cysts, diverticula, and adenocarcinoma.

Strengths and limitations: Strengths of the present study include the use of rapid autopsy to minimize protein degradation and autolysis, and the preparation of large tissue sections to demonstrate precise anatomical relations within all the tissues surrounding the urethral lumen. Limitations include the sample size and that all donors had advanced malignancy and had undergone previous therapy which may have had unknown tissue effects.

Conclusion: Proximal and distal glands expressing prostate-specific proteins were observed in tissue from all donors, and these glands were located only within the wall of the urethra.

Background: Childhood traumatic experiences have been associated with hypersexuality and sexual dysfunctions. However, the mediators of the interactions between these variables should be clarified in men.

Aim: This study aimed to investigate the interaction of early traumatic experiences, psychopathology, and sexuality with respect to erectile dysfunction (ED) and hypersexual behavior. The hypothesized model expected that traumatic experiences would be associated with hypersexual behavior and reduced sexual functioning through the mediation of body uneasiness and psychological distress.

Methods: The study was cross-sectional and observational. A total of 317 men were enrolled. Male patients with a primary complaint of ED and an indication for psychiatry referral represented the clinical sample (n = 116; mean ± SD age, 42.82 ± 16.89 years). Clinical classification was assessed with the Structured Interview on Erectile Dysfunction. The second sample (n = 201, 30.82 ± 11.94 years) was recruited from the general population. All participants were administered the following questionnaires: Brief Symptom Inventory, Childhood Trauma Questionnaire-Short Form, Hypersexual Behavior Inventory, Body Uneasiness Test-A, and 5-item International Index of Erectile Function.

Outcomes: Psychopathology and sexual functioning were assessed by a dimensional approach, and a multivariate model was computed by structural equation model analysis.

Results: When compared with the sample from the general population, the clinical sample exhibited a higher prevalence of early traumatic experiences, as measured by scores on the Childhood Trauma Questionnaire-Short Form (45.08 ± 14.25 vs 39.03 ± 10.22, F = 17.63, P < .001), and a higher tendency to engage in hypersexual behaviors (34.63 ± 13.55 vs 30.79 ± 12.44, F = 6.97, P < .01). Structural equation model analysis showed excellent fit indices indicating that early traumatic experiences predicted hypersexual behaviors and ED through the exacerbating mediating effect of body uneasiness and psychopathology.

Clinical implications: Clinicians should not limit their attention to the behavioral level when assessing sexual dysfunction in men; rather, they should also consider the complex psychopathologic consequences of childhood trauma. Integrated treatments that address the potential presence of childhood trauma with its wider psychological correlates (eg, emotion dysregulation, body uneasiness) might improve treatment response.

Strengths and limitations: The study reports novel data on the relationship among childhood maltreatment, male sexuality, and psychopathologic mediators with a dimensional assessment. However, the assessment was cross-sectional, and causality was mainly derived from previous studies.

Conclusion: The present study enriches the curr

Background: Intravesical instillation of hyaluronic acid (HA) has been associated with reduced sexual dysfunction in participants with recurrent urinary tract infections (rUTIs), but the efficacy of an oral treatment has never been investigated.

Aim: To investigate the efficacy of an oral preparation of HA, chondroitin sulfate, N-acetylglucosamine, and vitamin C in improving sexual and urinary symptoms in a cohort of reproductive-age participants with rUTI.

Methods: In a monocentric randomized crossover pilot trial, participants with rUTI who were referred to our institute between March 2022 and April 2023 were randomized 1:1 in 2 groups: intervention vs control. All participants had an oral preparation of cranberry, D-mannose, propolis extract, turmeric, and Boswellia twice a day for 3 months. The intervention group also included an oral preparation of HA, chondroitin sulfate, N-acetylglucosamine, and vitamin C once a day for 3 months. Crossover of treatment occurred at 3 months for an additional 3 months. At baseline and 3 and 6 months, participants were evaluated clinically and with the International Prostate Symptom Score (IPSS) and Female Sexual Function Index (FSFI). Descriptive statistics and logistic regression models tested the impact of the intervention on urinary and sexual symptoms at each follow-up assessment.

Outcomes: Improvement in sexual and urinary symptoms as measured by the FSFI and IPSS.

Results: Overall, 27 (54%) participants had an FSFI score <26.5 at enrollment. At 3 months, FSFI scores were higher in the intervention group vs control (P < .001), but IPSS scores were lower (P = .03). After crossover of treatment, FSFI and IPSS scores remained stable in the intervention group. However, after crossover, the control group showed a significant improvement in IPSS and FSFI scores (all P < .01) vs the 3-month assessment. At last follow-up, urinary and sexual symptoms were comparable between groups. In logistic regression analyses, the intervention group was associated with early improvement in sexual symptoms (odds ratio, 3.9; P = .04) and urinary symptoms (odds ratio, 5.1; P = .01) after accounting for clinical confounders.

Clinical implications: Combination treatment with HA, chondroitin sulfate, N-acetylglucosamine, and vitamin C is effective if started immediately or even after a few months from symptoms in participants with rUTI.

Strengths and limitations: The main limitation is the lack of long-term follow-up.

Conclusion: The oral formulation of HA, chondroitin sulfate, N-acetylglucosamine, and vitamin C could be an effective therapy against urinary and sexual distress in participants with rUTI (NCT06268483; ClinicalTrials.gov).
