INTRODUCTION
Evidence for noninvasive management of Peyronie's disease contains many options with varying levels of evidence for each. Many first-line treatments recommended by urologists lack strong evidence for their use.
AIM
We summarize the noninvasive (oral medications, topical medications, traction, vacuum erection devices, extracorporeal shock wave therapy, intracavernosal injections and electromotive therapy) treatment options for Peyronie's disease and provide the levels of evidence for each.
METHODS
A literature search of PubMed, EMBASE, Cochrane Library, and ClinicalKey databases was conducted, current up to April 2019.
MAIN OUTCOME MEASURE
For each treatment modality, we measured level of evidence, change in penile curvature, change in erectile function, the percentage of patients with improved angulation, and pain scores.
RESULTS
There is weak evidence to support the use of oral or topical medications. Higher levels of evidence exist for intracavernosal injections and extracorporeal shock wave therapy and may be helpful in certain patient populations.
CONCLUSION
The mechanisms behind Peyronie's disease are not fully understood. Penile injections provide the highest quality of evidence for noninvasive treatment. Ory J, MacDonald L, Langille G. Noninvasive Treatment Options for Peyronie's Disease. Sex Med Rev 2020;8:603-614.

Several strategies to optimize penile length in the presence of Peyronie's Disease (PD) have been described so far. In case of severe curvature and preserved erectile function, plaque incision/excision (PIG/PEG) are advisable in order to maximize penile length, despite the risk of postoperative erectile dysfunction (ED), recurrent curvature, or penile shortening. For men with PD deformities associated to a certain degree of ED several lengthening techniques associated to penile prosthesis (PPI) implantation can be considered. Because of the potential postoperative complications, the indication must be balanced between patient's risk factors and surgeon's experience. Furthermore, adjuvant surgeries, such as prepubic V-Y plasty, suspensory ligament release, suprapubic lipectomy, and ventral phalloplasty, can be performed simultaneously or in a staged fashion to maximize the outcomes. Restoration a decent penile length in the case of a severe PD represents a real challenge for reconstructive surgeons. We present a systematic review of the literature on the current practices for penile lengthening in severe PD, providing the reader with a practical overview on the existing surgical strategies and their surgical and functional outcomes.

Prostate cancer treatment can significantly impact erectile function, and penile rehabilitation has been proposed to improve the impacts. However, the effectiveness of penile rehabilitations after treatment of prostate cancer is scarce. The aim of this systematic review was to evaluate the effectiveness of different interventions of penile rehabilitation program after prostate cancer treatment. We conducted a comprehensive search of electronic databases, PubMed and Google Scholar, to identify randomized controlled trials that evaluated interventions for penile rehabilitation after prostate cancer treatment. Studies that met our inclusion criteria were systematically reviewed, and data were synthesized and analyzed. We identified 11 randomized controlled trials that evaluated different interventions for penile rehabilitation after prostate cancer treatment. The interventions included the use of phosphodiesterase type 5 inhibitors, intracavernous injections, vacuum erection devices, and penile rehabilitation programs. The data suggest that these phosphodiesterase inhibitors, intracavernous injections, vacuum erection devices, and penile rehabilitation programs are promising in improving erectile function after prostate cancer treatment. However, the optimal timing and duration of these interventions remain unclear, and there is a need for further research to determine their long-term effectiveness and safety. Healthcare providers should consider individualized approaches to penile rehabilitation, taking into account patient characteristics and preferences.

Review
Sexual function is a vital aspect of human health and is recognized as a critical component of cancer survivorship. Understanding and evaluating the impacts of radiotherapy on female sexual function requires precise knowledge of the organs involved in sexual function and the relationship between radiotherapy exposure and sexual tissue function. Although substantial evidence exists describing the impact of radiotherapy on male erectile tissues and related clinical sexual outcomes, there is very little research in this area in females. The lack of biomedical data in female patients makes it difficult to design studies aimed at optimizing sexual function postradiotherapy for female pelvic malignancies. This scoping review identifies and categorizes current research on the impacts of radiotherapy on normal female erectile tissues, including damage to normal functioning, clinical outcomes of radiation-related female erectile tissue damage, and techniques to spare erectile tissues or therapies to treat such damage. An evaluation of the evidence was performed, and a summary of findings was generated according to Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) Extension for Scoping Reviews guidelines. Articles were included in the review that involved normal female erectile tissues and radiotherapy side effects. The results show that little scientific investigation into the impacts of radiotherapy on female erectile tissues has been performed. Collaborative scientific investigations by clinical, basic, and behavioral scientists in oncology and radiotherapy are needed to generate radiobiologic and clinical evidence to advance prospective evaluation, prevention, and mitigation strategies that may improve sexual outcomes in female patients.

Meta-Analysis Review
BACKGROUND
Stem cell is considered a potential therapy for treating erectile dysfunction (ED), including diabetic mellitus erectile dysfunction (DMED), which was investigated in some preclinical studies. Several trials introduced stem cell into clinical practice, but divergences emerged.
AIM
To further investigate the therapeutic effects of stem cell on DMED in preclinical studies and investigate some possible factors that influence curative effects.
METHODS
The literature research was conducted in Web of Science and PubMed to retrieve studies utilizing stem cell to treat DMED. Revman 5.3 was used to perform subgroup analysis of intracavernosal pressure/mean artery pressure (ICP/MAP) and structural changes. Publication bias was assessed with Egger's test, funnel plot, and sensitivity analysis by Stata 15.0.
OUTCOMES
The ICP/MAP and structural changes before and after stem cell treatment.
RESULTS
Of 2,115 studies retrieved, 23 studies are eligible. Plus 10 studies from a meta-analysis published in 2016, 33 studies were enrolled. Pooled analysis showed that stem cell ameliorates damaged ICP/MAP (WMD 0.26; 95% CI 0.23-0.29; P < .001) and structural changes induced by diabetes. Subgroup analysis indicated that adipose-derived mesenchymal stem cell (ADSC) may have better efficacy than bone marrow-derived mesenchymal stem cell (BMSC) (χ= 4.21, P = .04; ADSC WMD 0.28, 95% CI [0.24-0.32] vs BMSC WMD 0.22 95% CI [0.17-0.26]). Transplantation type, diabetes type, and cell number make no difference to curative effects. Gene modification and therapy combination proved promising in improving the therapeutic effects of stem cell.
CLINICAL TRANSLATION
The evidence reminded that ADSC may be prior to BMSC in clinical trials and autotransplantation is probably not compulsory in the clinical practice of stem cell.
STRENGTHS AND LIMITATIONS
The study number and sample size are large enough. However, high degree of heterogeneity remains after subgroup analysis.
CONCLUSION
This meta-analysis suggests the efficacy of stem cell therapy for DMED and the possible superiority of ADSC over BMSC in erection restoration and structure renovation.

Review
INTRODUCTION
Phosphodiesterase type 5 (PDE-5) hydrolyzes cyclic guanylate monophosphate (cGMP) specifically to 5' GMP, promoting successful corporeal vascular relaxation and penile erection during sexual stimulation. Oral PDE-5 inhibitors such as sildenafil, vardenafil, tadalafil, and avanafil have provided noninvasive, effective, well-tolerated treatment for erectile dysfunction (ED) patients and, at the same time, stimulated both academic and clinical interests. Lately, some oral PDE-5 inhibitors were released as low-dose preparations with the concept of potential daily administration and long-term use.
AIM
To highlight the possible potential implications of low-dose long-term use of PDE-5 inhibitors.
METHOD
A systematic review was carried out until December 2015 based on a search of all concerned articles in MEDLINE, medical subjects heading (MeSH) databases, Scopus, The Cochrane Library, EMBASE, and CINAHL databases without language restriction. Key words used to assess the outcome and estimates for concerned associations were: PDE-5 inhibitors; erectile dysfunction; low-dose; long-term; sildenafil; tadalafil; vardenafil; avanafil.
MAIN OUTCOME MEASURES
Demonstrating different implications for low-dose long-term use of PDE-5 inhibitors.
RESULTS
Low-dose and/or long-term use of PDE-5 inhibitors was shown to put forth beneficial sound effects in different medical implications with potentials that could be extended for different utilities. These implications included sexual, urogenital, cardiovascular, pulmonary, cutaneous, gastrointestinal, and reproductive, as well as neurological disorders. However, it is evident that most potential appliances were carried out experimentally on preclinical studies with off-label indications.
CONCLUSION
Making use of and exploring low-dose and/or long-term use of several PDE-5 inhibitors for their possible implications seem to be valuable in different medical disorders. Increased knowledge of the drug characteristics, comparative treatment regimens, optimal prescribing patterns, and well-designed clinical trials are needed before these agents can be recommended for use.

Meta-Analysis
This present systemic review and meta-analysis was conducted to assess the effectiveness of low-intensity extracorporeal shockwave therapy (Li-ESWT) on erectile dysfunction (ED) based on the relevant randomised controlled trials (RCTs). A comprehensive search of databases, including Medline and Embase databases, from 1st January 2012 to 31st July 2020, that investigated the efficacy of Li-ESWT for ED, was searched. All the trials were divided into two groups: the experimental group received a different shockwave treatment, and the control group received the same treatment as the corresponding experimental group vibration, sound, etc) but no energy transmission. The primary endpoint was the International Index of Erectile Function-Erectile Function domain (IIEF-EF) score/questionnaire or erectile hardness score (EHS). The average IIEF-EF score was increased with statistical significance in the Li-ESWT group relative to the control group (p<0.001). Besides, the Li-ESWT group had evidently elevated changes in IIEF-EF score (p<0.001). Altogether seven articles reported the remarkably elevated EHS score with different total pulses (p<0.001). The favourable outcomes in terms of the average IIEF scores were observed in the cases developing mild or moderate ED (p<0.001). Compared with placebo treatment, Li-ESWT alleviates ED symptoms in patients, particularly those who have mild or moderate ED. Taken together, these results suggest that the Li-ESWT may hold promise for patients with ED. Key Words: Erectile dysfunction, Low-intensity extracorporeal shockwave therapy, Meta-analysis, Randomised controlled trials.

Review
BACKGROUND
Vascularized composite allotransplantation has become an alternative reconstruction technique for patients with a severe loss of substance. Today, five human penile transplantations have been reported. The objective of this literature review is to offer an updated overview of the technical and ethical questions surrounding penile transplantation compared with conventional phalloplasty.
MATERIAL AND METHODS
A systematic review was conducted of the literature from 2000 to 2020. A search of PubMed was performed using the keywords: "penile transplantation," "penis transplantation," and "penile vascularized composite allotransplantation." The criteria for the analysis were the type of study, surgical techniques, and ethical concerns.
RESULTS
Thirty-six articles were selected. These articles include reviews, case report, editorials, and preclinical studies. The first article was published in 2003, but the number of articles has increased after the second human transplantation in South Africa in 2014. Surgical techniques and the medication management specific to each team were successful in the 5 transplant cases, but several complications were noted.
CONCLUSION
Two decades of successful penile transplantations have proven the technique to be a viable solution to treat a penile amputation, allowing for a better esthetic and sensitive outcome paired with the possibility of natural urinary and erectile functions. Psychological impact of penile transplantation, selection of patients, complications of immunosuppressive therapies, and surgical technicity are the biggest penile transplantation challenges. Further experimental studies are necessary to produce standardized protocols to safely include penile transplantation in the conventional treatment of a penile amputation.

Review
INTRODUCTION
A series of previously neglected sexually related side effects to radical prostatectomy (RP) has been identified over the recent years. These include orgasm-associated incontinence (OAI), urinary incontinence in relation to sexual stimulation (UISS), altered perception of orgasm, orgasm-associated pain (OAP), penile shortening (PS), and penile deformity.
AIM
The aim of this article is to conduct a systematic review of the literature regarding the above-mentioned side effects.
METHODS
A predefined search strategy was applied in a thorough search of Medline, Web of science, and the online Cochrane library. The PRISMA guidelines for systematic reviews were followed, and protocol as well as search strategies was registered at http://www.crd.york.ac.uk/Prospero/ (RN: CRD42012003165).
MAIN OUTCOME MEASURE
The main outcome measure was incidence rates for the relevant side effects.
RESULTS
A total of 43 articles were included. OAI and UISS are experienced by 20-93% of RP patients at least a few times after surgery. Although these issues are associated to postoperative daytime incontinence, previous transurethral resection of the prostate (TURP) is the only known predicting factor. Alterations of orgasmic function are experienced by approximately 80% after RP. Erectile dysfunction seems to play an important role in waning orgasmic function. OAP is only experienced by a subset of the patients with reported rates varying between 3% and 19%. Sparing of the tips of the seminal vesicles has been shown to double the risk of OAP. PS occurs in 15-68% of RP patients. Nerve sparing and preservation of erectile function may help preserve penile length. With regard to all side effects, studies indicate that they are reduced over time.
CONCLUSIONS
The sexually related side effects summarized in this review are common after RP. Meanwhile, it is difficult to predict which patients are at risk. Daytime incontinence, previous TURP, a lack of nerve sparing, and erectile dysfunction are all associated with the above-mentioned sexually related side effects.

INTRODUCTION
Organ-sparing surgery (OSS) in penile cancer management aspires to maintain organ form and function and preserve health-related quality of life (HRQoL), yet there is a lack of integrated evidence exploring these outcomes.
OBJECTIVES
The aim sought to review HRQoL, functional, aesthetic, and psychological outcomes following OSS or radical penectomy for penile cancer.
METHODS
A systematic review of MEDLINE and Cochrane databases included studies reporting on function (sexual, urinary or sensory), genital appearance or HRQoL/psychological well-being following surgical treatment of primary penile cancer. English-language reports (2000-2022), incorporating patient-reported or objective clinical outcome measures, were eligible. Studies of nonsurgical treatment strategies and those in the context of metastatic disease were excluded. Data were compiled and analyzed.
RESULTS
Twenty-six studies were included. Sexual function was the most studied outcome (754 pooled respondents; 19 studies), most frequently with the original 15-item and abridged 5-item International Index of Erectile Function. Preservation of erectile function following OSS is generally described, with some reduction in overall sexual satisfaction cited. Heterogeneous assessment of voiding function with little preoperative evaluation render interstudy comparison difficult. Most patients appear able to void from a standing position following OSS, with spraying the most common symptom. Maintenance of some sensory function is described with both split-thickness skin grafting and urethral glanduloplasty following radical glansectomy. Limited studies suggest reasonable patient satisfaction with genital cosmesis post-OSS. A negative impact on HRQoL is described in most studies following penile cancer surgery, variably correlated with aggressiveness of penile surgery and addition of lymphadenectomy. Anxiety, depression, and reduced self-esteem have been reported in penile cancer survivors. Relationship well-being varies, with some survivors reporting this to be unchanged.
CONCLUSION
OSS can preserve elements of sexual, urinary, and sensory function, supporting advantages over radical penectomy for eligible patients. However, a comprehensive understanding remains limited due to small, heterogeneous patient cohorts, challenges in obtaining premorbid data, and variability in outcome measures. Standardization of patient-reported outcomes following OSS is desirable.
