Meta-Analysis
BACKGROUND
Hyaluronic acid is a glycosaminoglycan widely used in the fields of orthopedics, ophthalmology, and aesthetic medicine due to its significant ability to reduce the synthesis of pro-inflammatory proteins and its activity against oxidative stress, a feature of many degenerative illnesses.
OBJECTIVES
The objective of the present review is to provide a comprehensive narrative review of the most recent literature on the use of hyaluronic acid in andrology in order to facilitate the use of this therapeutic device in the common clinical practice of many physicians. Specific conditions covered in the review are Peyronie's disease, premature ejaculation, and penile enlargement.
MATERIALS AND METHODS
A broad and comprehensive literature search included Medline, EMBASE, and the Cochrane Libraries, with no time restriction up to December 2020 and restricted to English language publications. Unpublished studies were not included. The study was registered as "The role of hyaluronic acid in andrology: A systematic review and meta-analysis" in PROSPERO with the ID CRD42021223416.
DISCUSSION AND CONCLUSION
Hyaluronic acid is a valid choice for the treatment of Peyronie's disease in terms of the resolution of the acute phase of the disease and of contributing to stabilizing the disease as a bridge to potential surgery. Data, furthermore, suggest that hyaluronic acid is frequently associated with an overall clinical improvement, allowing the patient to resume normal sexual activity. With regard to premature ejaculation, data suggests hyaluronic acid-based treatments were effective in prolonging intra-vaginal ejaculation time. Furthermore, hyaluronic acid was found to be safe and well-tolerated, with main adverse events limited to local discomfort, ecchymosis, papule formation, and glans numbness, all of which were reported to resolve spontaneously. Last, with regard to penile enlargement, the overall perception of experts is that hyaluronic acid may be an extremely well-tolerated compound with potential for application in specific areas of male sexual health that are often neglected as compared to more common, and relatively simpler to treat, conditions.

Review
INTRODUCTION
Penile prosthesis (PP) implantation combined with grafting techniques is indicated in patients with Peyronie's disease (PD) and erectile dysfunction (ED) nonresponsive to medical and conservative treatment that present with residual penile curvature greater than 30°, severe penile deformity or significant penile shortening.
OBJECTIVES
To address the preoperative evaluation, the surgical procedure and the functional outcomes of grafting techniques combined with PP implantation in patients with PD and concomitant ED and to provide future perspectives on the matter.
METHODS
We performed a systematic review of the literature based on the PRISMA statement (PROSPERO ID: CRD42021224517). Records were identified by searching Medline, Scopus, The Cochrane Library and Web of Science databases as well as sources of gray literature from inception to December 2020. The quality of all included records was assessed based on a modified version of the Newcastle-Ottawa Scale for cohort studies.
RESULTS
A total of 935 patients with a mean age of 59.6 ± 9.2 years from 23 studies were included in this systematic review. All studies reported excellent short- and long-term postoperative results, as well as high satisfaction rates ranging from 80 to 100%. A mean increase of 2.7 ± 1.4 cm in penile length was observed. Among different grafting materials and different types of PP, no significant differences in terms of preoperative, perioperative and postoperative functional outcomes or complications were demonstrated. Still, the operative time was shorter in studies applying the collagen fleece TachoSil.
CONCLUSIONS
PP implantation combined with grafting is a safe and highly effective surgical procedure in patients with PD and concomitant ED. All grafting materials provide similar beneficial outcomes, but TachoSil subsequently reduces the operative time and does not require suturing. Still, no definite conclusions can be drawn regarding the superiority of one grafting technique over the other, as randomized clinical trials are lacking.

Meta-Analysis
BACKGROUND
The therapeutic role of extracorporeal shockwave therapy (ESWT) for Peyronie's disease (PD) has been controversial in a long term. We aimed to further evaluate the therapeutic effect of ESWT for PD on the basis of available high-quality studies.
METHODS
The PubMed, CENTRAL and Embase databases were searched for articles published from January 1st, 2000 to December 31, 2022. Only randomized controlled trials (RCTs) using ESWT to treat PD were included. Meta-analysis and forest plots were carried out using Review Manager 5.4.1 software, and outcomes were reviewed by 2 authors independently. Using the Risk of Bias assessment form (ROB-2) by Cochrane Collaboration for quality assessment. PRISMA 2020 guidelines were used in this article to achieve the quantitative and qualitative synthesis of data.
RESULTS
A total of four RCTs were included. 151 patients in the ESWT group and 150 patients in the control group. The meta-analysis results showed that ESWT could significantly reduce plaque size (OR 2.59, 95%CI 1.15 to 5.85, P = 0.02) and relieve pain (MD -1.55, 95%CI -2.46 to -0.64, P = 0.0008); but it has no significant effect on reducing the penile curvature (OR 1.93, 95%CI 0.87-4.26, P = 0.11) and improving sexual function (MD 2.6, 95%CI -1.63 to 6.83, P = 0.23), there is also no significant difference in complication rates between groups (OR 2.94, 95%CI 0.66 to 13.03, P = 0.16). The risk of bias of results is low. The limitations of this study are that the number of included studies is too small, some experimental outcomes are missing, and the expression of outcomes is not unified.
CONCLUSIONS
For PD, ESWT can be considered as a safe short-term treatment, which can reduce plaque size and relieve pain, but cannot improve penile curvature and sexual function. Its long-term efficacy remains to be discussed.

Meta-Analysis
INTRODUCTION
Peyronie's disease (PD) is a common penile disorder characterized by the formation of fibrous noncompliant hard nodules in the tunica albuginea of the penis. Collagenase Clostridium histolyticum (CCH) is an injectable drug that treats PD by enzymatically degrading plaque interstitial collagen. CCH has been used in patients with varying curvature, as well as in the acute and stable phases of the disease, through a variety of treatment regimens and combinations. We carried out a systematic review and meta-analysis to assess the efficacy of CCH combination therapies for PD.
METHODS
We selected 4 observational comparative studies and 3 randomized controlled trials including 532 participants from the PubMed, Embase, and Cochrane databases (until December 2023) to evaluate the efficacy of CCH combination therapies for PD. The primary outcome was clinical efficacy as evaluated by improvement in penile curvature and penile length, as well as by scores on the Peyronie's Disease Questionnaire (PDQ) for symptom bother, penile pain, and psychological symptoms. Continuous data were represented by mean difference (MD) and 95% CI. All data were analyzed by Review Manager version 5.3.
RESULTS
For penile length (MD, 0.81 cm; 95% CI, 0.17-1.45; P = .01), PDQ symptom bother (MD, -1.02; 95% CI, -1.83 to -0.21; P = .01), and PDQ penile pain (MD, -0.93; 95% CI, -1.50 to -0.36; P = .001), CCH combination therapy showed significantly greater improvements vs CCH monotherapy. However, in the other indicators, penile curvature and PDQ psychological symptoms, there was no significant difference between the therapies.
CONCLUSION
This meta-analysis supports that CCH combination therapies can partially increase penile length and ameliorate symptom bother and penile pain to some extent. However, CCH combination therapies still need to be evaluated through more high-quality research.

Review
INTRODUCTION
Peyronie's disease (PD) can have an immense psychological impact, with depression being a reported possible, severe consequence. To date, no literature reviews have systematically and critically assessed the relationship between PD and depression.
OBJECTIVES
The study sought to identify and critically appraise the current literature on the association between PD and depression.
METHODS
Studies had to address men with PD or probable PD and assess depression or depressive symptoms. Quantitative and qualitative, peer-reviewed, primary, empirical studies written in English or Danish were included. According to the guidelines for scoping reviews and the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews) guideline, we performed a systematic review of PubMed, PsycINFO, Embase, CINAHL, the Cochrane Library, and Web of Science. Reference lists of included studies were screened for additional sources. Gray literature was searched for in Google Scholar and Bielefeld Academic Search Engine. Data were charted using a data extraction form, and critical appraisal was performed using the QuADS (quality assessment with diverse studies) tool.
RESULTS
Thirteen studies were included. Most studies had a cross-sectional design, and also cohort studies and longitudinal observational studies without a control group were found. Depression was assessed mainly by validated questionnaires or diagnostic codes. Questionnaire studies found a prevalences of moderate to severe depression of 24% to 48%, while studies using diagnostic codes found depression in 4% to 37% of men with PD. The quality of the included studies varied from 38% to 82% of the maximum possible score in the QuADS assessment.
CONCLUSION
While most studies describe an association between PD and depression, the evidence is not comprehensive. The current literature is especially at risk of selection bias and the influence of confounding factors, and a direct causality between PD and depression cannot be established. Future research calls for more methodically rigorous studies as well as qualitative studies to understand the relationship.

BACKGROUND
The treatment of Peyronie's disease (PD) remains a dilemma as the true pathogenesis of PD remains an enigma. Consequently, new molecules and therapies continue to evolve. The safety and efficacy of conservative treatment for PD have not yet established.
OBJECTIVES
To provide the available information of the status of conservative therapy for PD.
METHODS
A systematic literature search was conducted using PubMed, EMBASE, and the Cochrane Library for English-language journal articles between January 2000 and July 2019, using the terms "Conservative treatment for PD", "medical treatment for PD", "non-invasive therapies for PD" and "minimally invasive therapies for PD". This systematic review was conducted in agreement with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) system. We also manually reviewed references from selected articles. The risk of bias in the included RCTs was assessed using the Cochrane Risk of Bias Assessment tool (RoB 2).
RESULTS
Conservative treatment is accepted as the initial treatment step in most of the cases. This kind of therapy includes various methods of treatment such as medical, non-invasive, and minimally invasive therapies. Ideal management of PD is not yet available. It is not possible to assess the value of treatment without well-designed, randomized, placebo-controlled, large-scale clinical studies.
CONCLUSION
Optimistically, in the near future, we may witness emergence of efficacious new agents and modalities to revolutionize medical, non-invasive, and minimally invasive treatment of this devastating condition.

Review
Priapism is defined as a persistent penile erection lasting more than 4 h. We searched the literature for reviews, case reports, and series for patients with lymphoproliferative disorders who developed priapism. The search involved all the lymphoproliferative disorders included in the revised 2016 World Health Organization classification of lymphoid neoplasms including chronic lymphocytic leukemia, multiple myeloma, Waldenström macroglobulinemia, and lymphomas. A total of 16 articles were found. The search included cases up to 4 January 2021. Priapism was seen most commonly as the first manifestation of lymphoproliferative disorders, rarely seen after treatment or after diagnosis.

INTRODUCTION
Penile prosthesis implantation (PPI), performed with or without adjunct straightening techniques, is one of the available surgical options in cases of Peyronie's disease (PD) with concomitant erectile dysfunction (ED). The aim of the study was to systematically identify and evaluate evidence regarding IPP in patients with PD and ED.
EVIDENCE ACQUISITION
Using Cochrane's methodological recommendations on systematic reviews, we conducted a systematic review of the literature on clinical research regarding the use of PPI, alone or in combination with any straightening maneuvers in the treatment of patients with PD and ED. The search was carried until January 2020. We included studies in English language with primary population patients with PD and ED who underwent IPP with the intent to treat the PD. All studies that were not original clinical research articles, reported insufficient data or included fewer than 5 patients were excluded from the final analysis.
EVIDENCE SYNTHESIS
In total 43 clinical articles with more than 2000 patients (N.=2143) investigating the effects of penile prosthesis implantation (PPI) for the treatment of PD with or without ED were included in the study. Depending on the severity of the penile curvature, additional penile deformities (i.e. hourglass deformity), penile length, prior operations and surgeons experience, 6 main categories of surgical techniques of PPI for penile straightening and treatment of PD were identified: PPI only, PPI with modelling of the penis, PPI with plication of the penis on the convex side of the curvature, PPI with plaque incision(s), PPI with plaque incision/excision plus grafting and PPI with grafting and penile lengthening.
CONCLUSIONS
Overall, patients with PD and ED can expect excellent outcomes with PPI against a minimal risk of side effects. No definite conclusions can be made regarding which technique is superior.

Meta-Analysis Review
CONTEXT
In patients with Peyronie's disease (PD), oral, injected, or topical agents provide limited efficacy. In this setting, combination of two or more conservative treatments may improve symptoms further.
OBJECTIVE
To explore the effects of available conservative combination therapies for active and stable PD through a systematic review and meta-analysis.
EVIDENCE ACQUISITION
We searched multiple databases and sources of gray literature until June 2021. We included randomized or observational comparative studies assessing any conservative combination therapies for PD. We undertook a random-effect meta-analysis when at least two studies employed the same treatment modality (PROSPERO: CRD42021224517).
EVIDENCE SYNTHESIS
Overall, 13 studies on active PD and ten on stable PD (1962 participants) were included. Most included studies raised methodological concerns. In patients with active or stable PD, the available evidence is inconclusive to support the use of any combination treatment modality, such as intralesional verapamil injections, antioxidants, and other oral, injected, or topical agents. Based on data availability, we performed a meta-analysis to compare the effect of collagenase Clostridium histolyticum (CCH) plus adjunctive mechanical therapies (penile traction or vacuum pump) versus CCH monotherapy on penile curvature and length in patients with stable PD. CCH and adjunctive mechanical therapies resulted in an additional decrease of 0.3° in penile curvature (95% confidence interval [CI]: -3.97 to 4.49, I = 0%) and in an increase of 0.5 cm in penile length (95% CI: -0.32 to 1.4, I = 70%) compared with CCH monotherapy.
CONCLUSIONS
The available combination treatment modalities, including the addition of adjunctive mechanical therapies to CCH, do not improve symptoms further compared with monotherapy and should not be implemented in patients with active or stable PD. Further high-quality randomized trials combining only recommended treatments are mandatory.
PATIENT SUMMARY
Despite the interest in and optimism for combination treatment modalities, the road to an effective conservative therapy for Peyronie's disease still seems long.

Meta-Analysis Review
BACKGROUND
Previous studies have suggested a protective effect of male circumcision on human papillomavirus (HPV) infections in males, and that this protection may be conferred to their female sexual partners.
OBJECTIVES
To synthesize the available evidence on the association between male circumcision and HPV infections in males and females.
DATA SOURCES
We searched MEDLINE, Embase, Scopus, Cochrane, LILACS, and ProQuest Dissertations & Theses Global for records published up to 22 June 2022.
STUDY ELIGIBILITY
We considered observational and experimental studies that assessed male circumcision status and HPV prevalence, incidence, or clearance in males or females for inclusion.
PARTICIPANTS
Males and their female sexual partners who were tested for genital HPV infection.
INTERVENTIONS
Male circumcision compared with no circumcision.
THE RISK-OF-BIAS ASSESSMENT
The Newcastle-Ottawa scale was used for observational studies, and the Cochrane risk-of-bias tool was used for randomized trials.
DATA SYNTHESIS
We estimated summary measures of effect and 95% CIs for the prevalence, incidence, and clearance of HPV infections in males and females using random-effects meta-analysis. We assessed the effect modification of circumcision on HPV prevalence by the penile site in males using random-effects meta-regression.
RESULTS
Across 32 studies, male circumcision was associated with decreased odds of prevalent HPV infections (odds ratio, 0.45; 95% CI, 0.34-0.61), a reduced incidence rate of HPV infections (incidence rate ratio, 0.69; 95% CI, 0.57-0.83), and an increased risk of clearing HPV infections (risk ratio, 1.44; 95% CI, 1.28-1.61) at the glans penis among male subjects. Circumcision conferred greater protection against infection at the glans than the shaft (odds ratio, 0.68; 95% CI, 0.48-0.98). Females with circumcised partners were protected from all outcomes.
CONCLUSIONS
Male circumcision may protect against various HPV infection outcomes, suggesting its prophylactic potential. Understanding the site-specific effects of circumcision on HPV infection prevalence has important implications for studies of HPV transmission.
