Introduction: The management of Peyronie's disease (PD) is a challenge for the clinician. Despite the lack of etiologic therapy, different nonsurgical approaches have often been empirically proposed. The most used treatment is based on nutraceutical drugs with antioxidant activity, although such an intervention remains controversial.

Objectives: We reviewed the evidence from the randomized controlled trials included in the recommendations of the American Urological Association (AUA), Canadian Urological Association (CUA), European Association of Urology, and International Society for Sexual Medicine.

Methods: We searched PubMed, Scopus, Web of Science, and Cochrane Library for randomized controlled trials, reviews, and guidelines on nutraceutical interventions for PD.

Results: Our analysis provides detailed information on potential interventions, underlying the inconsistent evidence. Acetyl esters of carnitine, although not recommended by any of the available guidelines, showed potential benefit in some selected studies. Omega-3 fatty acids are not recommended due to withdrawn study evidence. The CUA and AUA were the only societies to consider the use of coenzyme Q10. While the CUA suggested that it might be offered as a treatment option, the AUA refrained from taking a definitive stance due to insufficient evidence. Similarly, conflicting recommendations have been produced on potassium para-aminobenzoate. While the CUA considers potassium para-aminobenzoate potentially useful in slowing PD progression, the AUA deems the evidence insufficient. Conversely, both the International Society for Sexual Medicine and European Association of Urology do not recommend its use.

Conclusion: This critical comparative analysis of the most recent guidelines produced by the leading scientific societies highlights some inconsistencies in the recommendations on nutraceutical intervention for PD, even within a background of overall ineffectiveness of this treatment approach.

Introduction: Traditional reservoir placement (RP) into the space of Retzius during three-piece inflatable penile prosthesis implantation has been associated with serious bladder, iliac vessel, and bowel complications, encouraging the development of "ectopic" RP methods.

Objectives: In this study we sought to document an up-to-date, comprehensive analysis of ectopic RP techniques regarding both patient satisfaction and clinical complications.

Methods: A PubMed, Ovid MEDLINE, and Cochrane Library literature search of English language articles from 1966 to 2023 with keywords "inflatable," "penile prosthesis," "reservoir," and "placement" gave 179 publications, 70 of which were included in a comprehensive chronology and investigation after review. Overall, 12 retrospective studies detailing 9 ectopic RP techniques were compared for discussion.

Results: Sufficient data for comparison were found for 9 ectopic RP methods: posterior/anterior to transversalis fascia (PTF/ATF); high submuscular (HSM); HSM "Five-Step" technique (HSM-FST); lateral retroperitoneal (LR); sub-external oblique (SEO); direct vision, transfascial (DVT); low submuscular with transfascial fixation (LSM w/ TFF); and midline submuscular reservoir (MSMR). Although rare, serious complications have occurred with the use of ectopic RP techniques: 2 bladder perforations on implantation with PTF RP, a delayed bowel obstruction with HSM RP, and a colonic injury in a patient with a history of colon surgery with LR RP. Generally, herniation is the most relevant clinical complication in ectopic RP. At the time of this review there was no reported herniation with LR, SEO, LSM w/ TFF, or MSMR, likely due to fixation steps and/or reinforced spaces. Regarding patient satisfaction, HSM, HSM-FST, and LSM w/ TFF had similarly high rates of patient satisfaction while other techniques had no patient satisfaction data available. Importantly, reservoir palpability/visibility relates directly to patient satisfaction. Levels of palpability and/or visibility were reported in patients who underwent PTF/ATF, HSM, HSM-FST, SEO, and LSM w/ TFF, whereas no palpability was reported in patients who underwent LR, DVT, and MSMR.

Conclusion: Proper comparison of ectopic methods is not possible without standardized patient surveys, consistent complication reporting, and larger sample sizes, indicating the need for a large, prospective, multisurgeon trial.

Introduction: Vulvodynia is a complex and multifactorial medical condition characterized by pain in the vulvar area without any identifiable cause. Vulvodynia is underdiagnosed, leading to increased risk of sexual dysfunction and reduced quality of life. Irritable bowel syndrome (IBS) is a gastrointestinal disorder predominantly affecting women. Vulvodynia and IBS frequently co-occur in women, with a 2- to 4-fold increased likelihood of IBS diagnosis in those with vulvodynia. These conditions may share underlying causes, highlighting the need for research to better understand their shared pathophysiology and develop effective therapeutics.

Objective: The aim of this scoping review was to assess the evidence of simultaneous presentation of IBS and vulvodynia.

Methods: A comprehensive search was conducted in 6 databases between inception of database and August 2023: PubMed, Web of Science, Scopus, Science Direct, Google Scholar, and Cochrane Library. Studies included primary research about IBS and vulvodynia in terms of presentation overlap, diagnosis, or treatment. Data were extracted from eligible studies, summarized, and collated.

Results: Of the 306 unique articles identified, 33 were included in the final analysis: 20 cross-sectional studies, 4 case-control studies, 2 case reports, 4 cohort studies, 2 quasi-experimental studies, and 1 randomized trial. Common themes included a high prevalence of overlapping vulvodynia and IBS with a significant diagnostic delay in vulvodynia, mast cell involvement and visceral hypersensitization as common pathophysiology, and the need for a multimodal treatment.

Conclusion: Our review adds to the evidence that there is an association between vulvodynia and IBS. Despite this, research on the underlying molecular mechanisms of this association is scarce, and diagnostic delays persist for vulvodynia. Increasing awareness of the overlap of these conditions will improve screening for vulvodynia in the patient population with IBS, thereby improving the diagnostic delay, and understanding the pathophysiology will enable treatment strategies that address both conditions.

Introduction: Testicular prosthesis can be placed at the time of orchiectomy for many benign and malignant testicular conditions. The American Urological Association guidelines recommend discussing the implant prior to the procedure.

Objectives: We review the literature on testicular prosthesis placement with respect to the history, psychological impact, surgical technique, complications, satisfaction, and novel emerging medical implications.

Methods: A Medline search was conducted with several terms related to and including "testicular implant," "testicular prosthesis," "testicular implant satisfaction," and "testicular implant history." Twenty articles were identified with patient satisfaction data. Satisfaction with the comfort, shape, size, and weight was reported in addition to satisfaction with the device from 13 studies.

Results: Overall satisfaction of testicular prosthesis is reported as high. Patients should be offered an implant at the time of orchiectomy or at any subsequent time based on their preference.

Conclusion: This article presents a contemporary and comprehensive review of the literature on testicular prostheses. Satisfaction rates following implantation remain consistently high. Additionally, innovative approaches are being investigated, including the exploration of novel implants for treating hypogonadism. Moreover, the utilization of 3-dimensional printing technology is revolutionizing the creation of testicular implants, aiming to achieve a texture and density closely resembling human testicles.

Introduction: One of the changes caused by pelvic cancers is the decrease in patients' sexual function, which influences their quality of life (QoL) during and after treatment. Sexual dysfunction (SD) is associated with severe ejaculatory dysfunction, sexual dissatisfaction, reduced libido and sexual desire, decreased intensity of orgasm, difficulty in erection, and lower sexual frequency.

Objectives: This systematic review investigated the effectiveness of conservative treatments (nonsurgical and nonpharmacologic) for SD in males with pelvic cancer.

Methods: Systematic searches were performed in the Cochrane Library, PubMed, CINAHL, PEDro, Embase, and VHL databases in September 2023 by using MeSH terms related to population, study design, intervention, and outcome.

Results: Only prostate cancer studies were included due to a lack of studies in other treatments. Studies used pelvic floor muscle training (8 studies); biofeedback (1 study); a penile vibrator (1 study); electrostimulation (2 studies); shock wave therapy (2 studies); aerobic, resistance, and flexibility exercises (2 studies); and a vacuum erection device (1 study). All articles assessed sexual function and reported improvements in the intervention group, including 5 with no differences between the groups. Articles involving shock wave therapy described improvements in SD but were not clinically relevant. Studies evaluating QoL reported benefits in the experimental groups. Adverse effects of a vacuum erection device and penile vibrator were reported.

Conclusion: Conservative treatments are more effective than others in treating SD in men with prostate cancer. Further studies are needed to assess the unwanted effects of these treatments. In this study, we found evidence that this type of therapy improves sexual function and QoL in this population.

Introduction: Health care workers represent a substantial demographic whose welfare and work efficiency are crucial to public health and societal well-being. However, the prevalence of sexual dysfunction within this group is often overlooked, despite its significant occurrence.

Objective: To evaluate the worldwide prevalence of sexual dysfunction among health care workers.

Methods: A comprehensive systematic review and meta-analysis of observational studies ranging from 2003 to 2023 were performed to compile prevalence estimates of sexual dysfunction among health care workers. A random effects model was implemented to amalgamate the prevalence analysis. Study heterogeneity was discerned by I2 and χ2 statistics. To assess potential publication bias, an Egger's test and a funnel plot were employed.

Results: This meta-analysis incorporated 39 studies from 16 countries, encompassing 44 017 health care workers. The pooled prevalence of sexual dysfunction among health care workers was 46.79% (95% CI, 38.09%-55.68%), with a slightly higher prevalence of 49.57% (95% CI, 38.18%-61.01%) among clinical health care workers. The most prevalent forms of sexual dysfunction identified were loss of libido (51.26%), erectile dysfunction (36.99%), sexual dissatisfaction (36.90%), pain during intercourse (28.23%), orgasmic disorders (25.13%), low sexual arousal (23.54%), and lubrication disorders (22.62%). Among various health care professions, nurses exhibited the highest prevalence of sexual dysfunction (56.29%), followed by doctors (37.63%) and other health care workers (24.96%). Additionally, female health care workers experienced a higher prevalence of sexual dysfunction (47.61%) as compared with their male counterparts (32.01%).

Conclusion: This study indicates that nearly half of health care professionals report experiencing sexual dysfunction, with loss of libido being the most common manifestation. Addressing this issue requires a multistakeholder approach.

Introduction: Although society still holds age-related stereotypes dismissing the sexuality of aging individuals, older adults remain sexually active and find sexuality to be an important part of their quality of life. Primarily oriented toward a biomedical and dysfunctional lens, prior research neglected the subjective well-being of elderly individuals, especially partnered adults and couples aged 60 years or more. Shedding a more positive light on this area of life could promote older individuals' and couples' sexual well-being.

Objectives: This scoping review aimed to synthetize the studies including community samples of partnered adults or couples over 60 who reported on various indicators of subjective sexual well-being including sexual satisfaction, distress, and function using validated measures.

Methods: Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMAScR), the electronic literature search was conducted using PubMed, PsycINFO, Medline, and CINAHL for peer-reviewed journal articles published before July 2023.

Results: Results showed how relational variables such as relationship satisfaction and intimacy emerge as important correlates of older adults' sexual well-being.

Conclusion: Avenues for future research arising from gaps in the studies identified thorough this scoping review, including the underrepresentation of sexual/gender diverse individuals and the use of single and/or non-validated items to assess sexual well-being, are discussed.

Introduction: Bladder cancer ranks 17th in prevalence of cancer types among women, and the trend is rising. The increased risk of female sexual dysfunction (FSD) after radical cystectomy (RC) underscores the need for greater focus on preserving and mitigating FSD.

Objectives: To place greater emphasis on the importance of female sexual function (FSF) in the treatment of bladder cancer and stimulate additional research to discover more effective solutions for enhancing the overall quality of life.

Methods: This review used a narrative approach. Previous reviews on FSF after RC have provided limited and 1-sided solutions due to the lack of research. What makes this review unique is its innovative approach: it includes all available measures curing FSD as well as comparative analyses based on experimental data, thus making the findings more comprehensive. A detailed perspective of treatments for female bladder cancer is provided, including nerve- and organ-sparing RC, robot-assisted RC, and radiotherapy. We also analyze the impact of treatments for female bladder cancer on postoperative FSD. Additionally, solutions for addressing or alleviating postoperative FSD are summarized, such as urinary diversion, vaginal reconstruction, and drug and nondrug treatment.

Results: Research has suggested that robot-assisted nerve- and organ-sparing RC is promising. Moreover, orthotopic neobladder among urinary diversions without a stoma helps to maintain a positive female body image. If part of the anterior vaginal wall must be removed during RC, vaginal reconstruction can restore the dimensions with synthetic grafts and biologic scaffolds. Additionally, postoperative measures, such as vaginal laser and hormone therapy, and use of vaginal dilators and lubricants have a significant role in reducing distress caused by FSD to provide maximum relief.

Conclusions: To support FSF after RC, various interventions are needed, and urologists must focus on patient recovery while minimizing treatment impact on FSF as much as possible.

Introduction: Erectile dysfunction (ED) is a common issue that affects older men and is often associated with various health conditions. Phosphodiesterase 5 inhibitors are commonly used to treat ED; however, their effectiveness may be limited, or the medication may be contraindicated. Therefore, topical gels are being developed as an alternative option for the pharmacologic treatment of ED.

Objectives: This review aimed to provide an overview of the efficacy and safety of topical agents for the treatment of ED.

Methods: The PubMed, Cochrane, Embase, and Web of Science databases were searched. Articles were included that investigated ED and topical agents operating through the skin of the penis, evaluated the effectiveness of the treatment, and involved patients randomized into groups.

Results: Topical alprostadil, glyceryl trinitrate (MED2005), and an over-the-counter formulation (MED3000) were used as alternative treatments for ED in 7 articles, which included 3475 patients. Topical alprostadil induced an erection in 67% to 75% of patients. Adequate erections for vaginal penetration were reported in 38.7% of the alprostadil-treated patients vs 6.9% of the placebo-treated patients. Topical alprostadil significantly and dose dependently improved the total score change on the International Index of Erectile Function as compared with the placebo. MED2005 exhibited a rapid onset of action, with nearly 70% effectiveness within 10 minutes. MED3000 met the minimal clinically important difference threshold of a 4-point increase on the erectile function domain of the International Index of Erectile Function, with an improvement of 5.73 points in 24 weeks. Topical therapy for ED also had acceptable safety profiles.

Conclusion: Topical agents via various mechanisms are effective and well-tolerated treatments for ED. A fast-acting drug that significantly reduces side effects as compared with other options has been discovered. However, its efficacy relative to current first-line therapies remains unclear. Topical agents present a viable therapeutic alternative for individuals who are unable or unwilling to take oral phosphodiesterase 5 inhibitors.

Introduction: Androgens play important roles in regulating the growth and development of the male reproductive system and maintaining libido and erectile function. The specific mechanisms by which androgen deficiency leads to erectile dysfunction (ED) are not yet fully understood.

Objectives: To understand the mechanisms and treatment of androgen deficiency-related ED.

Methods: A literature search in the past 10 years was conducted in PubMed and Google Scholar to determine the effects of androgen deficiency on erectile function and the treatment of androgen deficiency.

Results: Androgen deficiency can be caused by hypothalamic-pituitary lesions and injuries, testicular-related diseases and injuries, endocrine and metabolic disorders, the side effects of medication, and age. Androgen deficiency can lead to ED by inhibiting the NOS/NO/cGMP pathway (nitric oxide synthase/nitric oxide/cyclic guanosine monophosphate) and altering the expression of ion channel proteins, as well as by inducing oxidative stress, death, and fibrosis in penile corpus cavernosum cells. Testosterone replacement therapy is effective at improving the serum testosterone levels and erectile function in patients with androgen deficiency. For patients who need to maintain a low androgenic state, erectile function can be improved by lifestyle changes, treatment with phosphodiesterase type 5 inhibitors, low-intensity extracorporeal shock wave therapy, and stem cell therapy.

Conclusions: Androgen deficiency can affect the structure and function of the penile corpus cavernosum, leading to ED. Areas of further study include how androgen replacement therapy can improve erectile function and how to improve the maintenance of erectile function in patients with hypoandrogenic status.
