From October 2023 to May 2024, the Arizona Sexual Experience Scale (ASEX) was used to evaluate the sexual arousal and orgasm of one thousand heterosexual cisgender Spanish adults (433 men and 567 women), aged 18-77 years, in both contexts. A multivariate analysis of covariance (MANCOVA) and an analysis of variance (ANOVA) were conducted. Men reported better sexual function as measured by the ASEX questions than women did (p values between < 0.001 and 0.021). With respect to sexual context, men's arousal and ability to reach orgasm varied, with greater arousal in sexual relationships (p < 0.042) and a greater ability to reach orgasm during masturbation (p < 0.022). Finally, the sex x sexual context interaction was significant (p < 0.001), so men and women presented different patterns in arousal, penile erection/vaginal lubrication, ability to reach orgasm and satisfaction with orgasm (p values between < 0.001 and 0.034) when the contexts of solitary masturbation and sexual relationships were compared.

Given the association with androgens and penile/urethral health, we aim to evaluate whether patients on androgen deprivation therapy (ADT) undergoing IPP or AUS surgery are at increased risk for reintervention, complication, or infection. We queried the TriNetX database for adult males receiving IPP or AUS. The ADT cohort included those on ADT 3 months before or any time after surgery. We performed sub-analysis for leuprolide and bicalutamide. Cohorts and outcomes were defined by Current Procedural Terminology and International Classification of Diseases codes. Propensity score matching was performed using age, prostate cancer, history of prostatectomy, and history of radiation. Outcomes were reintervention (revision, removal, or replacement), infection, and complication. Analytics were performed in March 2024. 13,432 patients received an IPP and 5676 received an AUS, 465 and 745 of whom were on ADT, respectively. The only significant AUS analysis was for patients on abiraterone having fewer reinterventions (10.5% vs 20.8%, RR = 0.50 [0.29, 0.88]). Patients receiving an IPP with ADT had fewer reinterventions (7.2% vs 12%, RR = 0.60 [0.39, 0.92]) and complications (12.7% vs 18.5%, RR = 0.68 [0.49, 0.95]).

We assess the efficacy and patients' experience with sildenafil 50 mg OSF in men with ED who were taking the sildenafil oro-dispersible film (ODF). Demographics and clinical data from 70 consecutive men with mild-moderate ED were analysed. Patients were treated with sildenafil 50 mg ODF for 12 weeks (follow-up 1), then, after 2-week washout, were administered sildenafil 50 mg OSF for 12 weeks (follow-up 2). At each follow-up, patients completed the International Index of Erectile Function (IIEF), the Patient Global Impression of Improvement (PGI-I), and the Psychological and Interpersonal Relationship Scales-Short Form (PAIRS-SF) questionnaires. Descriptive statistics described the whole cohort. The Wilcoxon Signed Rank Test assessed potential differences in psychometric scores at different follow-up assessments. Logistic regression analyses tested the associations between study variables and satisfaction after sildenafil OSF treatment. Overall, median age was 56 (51-62) years, and median IIEF-EF score was 14 (12-17).

We conducted a systematic review and meta-analysis of randomised-controlled trials (RCTs) following PRISMA guidelines. Outcomes included intravaginal ejaculatory latency time (IELT), Premature Ejaculation Profile (PEP) scores, and complications. Data were analysed using Microsoft Excel and R. ROB-2, Eggers test, and GRADE assessed risk of bias, publication bias, and certainty of evidence (CoE). Three RCTs were eligible, and covered data from 228 patients with (1:1) randomisation into intervention and control arms (100 units of botulinum toxin-A in 10 mLs versus 10 mLs of 0.9% NaCl). IELT increases were noted with averages of 39.6, 11.5, and 2.4 s at 1, 3, and 6 months of follow up, respectively.

Patients diagnosed with SRPE from 2017-2024 by strict criteria were recruited into our novel pathway. This included a comprehensive diagnostic panel to exclude potential confounding causes of penile pain through history, clinical examination, laboratory tests and imaging studies. Once SRPE is diagnosed a stepwise approach of initiating Baclofen (10 mg daily at night), followed by polysomnography (PSG) (to explore sleep architecture and implement sleep medication and/or treat obstructive sleep apnoea accordingly) and pelvic floor physiotherapy (PFP) (to target pelvic floor hypertonicity). Symptoms were evaluated using a dedicated questionnaire during clinic follow-up. Patients achieving a symptom-free period of >6 months were discharged. Twenty patients with SRPE (mean age 46.2 ± 11.6 years) were included. The mean delay to referral was 3.5 ± 3.1 years, with a mean of 3.3 ± 2.1 SRPE episodes per night (range 1-7) lasting 33 ± 23.7 minutes. 85% of patients completed most of the pathway.
