Abstract
In 2022, the global prevalence of erectile dysfunction (ED) was estimated to be at least 150 million cases. This number is greatly suspected to be underestimate as most men withhold information about ED. Also, about 15% of world population have infertility troubles, and male factors are responsible for almost half of these cases. Studies have shown that the quality of semen has decreased in the past several decades owing to various health factors and environmental toxicants. The current medical interventions involve the inhibition of phosphodiesterase 5 which suffer from serious side effects and costly. One of the popular and most sought interventions are the natural and nutritional remedies as they are foods in essence and potentially with no harm to the body. Therefore, the goal of this paper is to provide a review of the most common nutritional aphrodisiacs with increasing libido and fertility highlighting the potential active constituents as well as the underlying mechanisms.

Using the forest plot to compare citation achievements in bibliographic and meta-analysis studies since 2011 using data on PubMed Central: A retrospective study. Medicine (Baltimore) 2022; 101:e29213. [PMID: 35801759 PMCID: PMC9259113 DOI: 10.1097/md.0000000000029213] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/04/2023] Open
Abstract
BACKGROUND We saw a steady increase in the number of bibliographic studies published over the years. The reason for this rise is attributed to the better accessibility of bibliographic data and software packages that specialize in bibliographic analyses. Any difference in citation achievements between bibliographic and meta-analysis studies observed so far need to be verified. In this study, we aimed to identify the frequently observed MeSH terms in these 2 types of study and investigate whether the highlighted MeSH terms are strongly associated with one of the study types. METHODS By searching the PubMed Central database, 5121 articles relevant to bibliometric and meta-analysis studies were downloaded since 2011. Social network analysis was applied to highlight the major MeSH terms of quantitative and statistical methods in these 2 types of studies. MeSH terms were then individually tested for any differences in event counts over the years between study types using odds of 95% confidence intervals for comparison. RESULTS In these 2 studies, we found that the most productive countries were the United States (19.9%), followed by the United Kingdom (8.8%) and China (8.7%); the most number of articles were published in PLoS One (2.9%), Stat Med (2.5%), and Res Synth (2.4%); and the most frequently observed MeSH terms were statistics and numerical data in bibliographic studies and methods in meta-analysis. Differences were found when compared to the event counts and the citation achievements in these 2 study types. CONCLUSION The breakthrough was made by developing a dashboard using forest plots to display the difference in event counts. The visualization of the observed MeSH terms could be replicated for future academic pursuits and applications in other disciplines using the odds of 95% confidence intervals.

A Critical Analysis of Reporting in Systematic Reviews and Meta-Analyses in the Peyronie's Disease Literature. J Sex Med 2022; 19:629-640. [PMID: 35177375 PMCID: PMC9575169 DOI: 10.1016/j.jsxm.2022.01.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2021] [Revised: 12/17/2021] [Accepted: 01/12/2022] [Indexed: 11/23/2022]
Abstract
BACKGROUND Despite an increasing number of publications on Peyronie's disease (PD), evidence-based clinical decision-making remains challenging due to the small number of well-designed clinical trials. AIM To perform a critical analysis of reporting quality in PD systematic reviews (SR) and meta-analyses (MA). METHODS Study protocol registration was performed on the Open Science Framework platform. In January 2021, a systematic electronic search of the Medline/PubMed, Embase, Ovid, Scopus, Joanne Briggs Institute, and Cochrane databases was performed. Search terms included "Peyronie's disease" and "systematic review OR meta-analysis OR meta-analysis." Eligibility criteria were English-language, relevance to PD and specification of "systematic review" or "meta-analysis" in the title or abstract. Oxford Center for Evidence-Based Medicine levels of evidence were used to classify original studies reviewed within each publication. Risk of bias was assessed using the ROBIS tool. Data were tabulated and reported as means with standard deviation, median with interquartile range and t-testing as appropriate. Strength of association between variables was calculated using Pearson correlation coefficient. Statistical analyses were performed on RStudio (version 1.4.1106). OUTCOMES Outcomes included review type, level of evidence, authorship, journal, publication date, "A MeaSurement Tool to Assess systematic Reviews" (AMSTAR-2) score and "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) score. RESULTS From 1974 to 2021, 340 articles were identified. After review, 17 full length articles were included. Thirteen were SR, 2 MA and 2 was combined. Significant heterogeneity was seen in evidence level of included studies. There was median 54% adherence to AMSTAR-2 criteria and 74% adherence to PRISMA criteria. Overall AMSTAR-2 confidence rating was Critically Low in 11 of 17 studies. Correlation analysis revealed very high positive association between AMSTAR 2 and PRISMA adherence (+0.95). ROBIS revealed "High" concern regarding methods used to collect data and appraise 12/17 studies (71%), and "High" concern regarding synthesis and findings in 8 of 17 studies (47%). CLINICAL IMPLICATIONS Many SR include markedly heterogenous levels of evidence and fail to meet accepted methodological criteria for reporting. STRENGTHS AND LIMITATIONS Main strengths include extensive literature review and analysis of standardized study reporting. One limitation is that aggregate scoring of AMSTAR-2 and PRISMA is not intended as primary method of quality assessment; however effect was minimized by reporting critical domains, overall quality assessments and specifics on globally poorly reported domains. CONCLUSION More high quality randomized controlled PD trials are necessary; SR and MA should focus on these studies alone. Bole R, Gottlich HC, Ziegelmann MJ, et al.

The Effect of Phosphodiesterase-type 5 Inhibitors on Erectile Function: An Overview of Systematic Reviews. Front Pharmacol 2021; 12:735708. [PMID: 34557099 PMCID: PMC8452927 DOI: 10.3389/fphar.2021.735708] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Accepted: 08/24/2021] [Indexed: 01/08/2023] Open
Abstract
Background: Multiple systematic reviews explore the effect of phosphodiesterase type 5 (PDE5) inhibitors on erectile dysfunction (ED), with each study addressing specific outcomes. However, physicians and policymakers require a holistic approach of this topic. Objective: To summarize the current evidence regarding the efficacy and safety of PDE5 inhibitors for the management of ED through an overview of systematic reviews. Methods: Studies were identified by searching PubMed, Web of Science, Cochrane Library and Scopus databases, as well as sources of grey literature until June 12, 2021 (PROSPERO: CRD42020216754). We considered systematic reviews, meta-analyses or network meta-analyses of randomized trials that provided outcomes about the efficacy and safety of any approved PDE5 inhibitor (avanafil, sildenafil, tadalafil and vardenafil). We constructed forest plots for meta-analytic effects regarding the change in erectile function, adverse events and dropouts after administration of PDE5 inhibitors in the general population and in specific patient groups. Results: We included 23 studies with 154,796 participants and a total of 258 meta-analytic effects. Sildenafil 25 mg [Weighted Mean Difference (WMD): 13.08, 95% Confidence Interval (CI): 10.1-16.06] seemed to be statistically superior to all interventions in improving erectile function compared to placebo, but studies with low-dose sildenafil are lacking. Moreover, comparing among different PDE5 inhibitors, sildenafil 50 mg or sildenafil 100 mg were considered the most effective compounds in the general population. The latter derived, however, predominantly from indirect comparisons among different PDE5 inhibitors. Still, sildenafil 100 mg was associated with more treatment-related adverse events and dropouts. Interestingly, low-dose daily tadalafil may be more effective than high-dose on-demand tadalafil (WMD: 1.24, 95% CI: 0.03-2.44). Furthermore, testosterone and PDE5 inhibitors in patients with ED and hypogonadism seem to further improve symptoms, while the addition of a-blockers in patients with urinary symptoms treated with PDE5 inhibitors does not provide additional benefits (WMD: −0.8, 95% CI: −1.65-0.06). Conclusion: Although the efficacy and safety of PDE5 inhibitors, compared to placebo, is well-documented, the existing evidence comparing different PDE5 inhibitors is low. Therefore, high-quality, head-to-head, trials comparing different PDE5 inhibitors are necessary to determine their ideal dosage and formulation based on their safety and efficacy profile.

Abstract
INTRODUCTION Phosphodiesterase-type 5 inhibitors (PDE5i) are the recommended first-line treatment for erectile dysfunction. Previous systematic reviews and meta-analyses suggest that they are a safe and effective option in many patient groups. Similarly, PDE5i may be effective as part of combination therapy in non-responders to PDE5i. We will generate an overview of systematic reviews, meta-analyses and network meta-analyses aiming to summarise the available knowledge regarding the efficacy and safety of PDE5i in the general population and in multiple subgroups of patients. METHODS AND ANALYSIS This overview was designed in accordance with the PRIO-harms and Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines and its protocol was registered at PROSPERO. We will systematically search PubMed, Web of Science, Cochrane Library and Scopus databases from inception to November 2020 without any language restrictions. We will include systematic reviews or meta-analyses: (1) comparing the efficacy and safety of any dose of PDE5i with each other, with placebo or with other effective treatments for the management of erectile function; (2) exploring the use of any PDE5i alone or in combination with other treatment modalities in the general male population or in specific subgroups and (3) conducted with systematic procedures. Our overview will employ the AMSTAR 2 tool to evaluate the quality of the included studies and the Grading of Recommendations Assessment, Development and Evaluation approach to assess the strength of evidence for all outcomes. We will construct forest plots of risk estimates with the corresponding CI for all outcomes. ETHICS AND DISSEMINATION In this overview, we will undertake an extensive literature search in an attempt to evaluate the potential benefits and risks of treatment with one PDE5i versus another or versus placebo and provide recommendations for clinicians and policy-makers. No ethical approval is required. PROSPERO REGISTRATION NUMBER CRD42020216754.

Abstract
Objective To investigate the therapeutic effect of implanting a three-piece inflatable penile prosthesis (IPP) combined with the phosphodiesterase-5 inhibitor sildenafil in severe erectile dysfunction (ED) patients. Methods This randomized controlled study included 123 ED patients. Sixty-two patients received the IPP implantation and 61 patients received the IPP implantation and the phosphodiesterase-5 inhibitor sildenafil. Erectile function and sexual life quality were evaluated using the five-item International Index of Erectile Function (IIEF) and modified Sexual Life Quality Questionnaire–Quality of Life domain (mSLQQ-QoL), respectively. Serum interleukin (IL)-6, IL-8, tumor necrosis factor (TNF)-α, vascular cell adhesion molecule (VCAM)-1, and intercellular adhesion molecule (ICAM)-1 levels were assessed. Kaplan–Meier curves were used to assess the overall IPP survival. Results Implantation of the three-piece IPP with sildenafil improved erectile function and sexual life quality, alleviated the inflammatory response, reduced the complication rate, and improved overall IPP survival. Conclusion Implantation of the three-piece IPP combined with a phosphodiesterase-5 inhibitor significantly improved clinical outcomes and the prognosis in ED patients.

Abstract
BACKGROUND Male factor infertility (MFI) is a common medical condition which requires high-quality research to guide clinical practice; however, systematic reviews (SRs) and meta-analyses (MAs) often vary in quality, raising concerns regarding the validity of their results. We sought to perform an objective analysis of SRs and MAs in MFI treatment and management and to report on the quality of published literature. METHODS A comprehensive search in PubMed/MEDLINE and Embase was used to identify relevant publications. Primary search terms were male infertility, male sterility, and male subfertility. Two authors independently performed searches, screened citations for eligibility, extracted data for analysis, and graded methodological quality using the validated AMSTAR (A Measurement Tool to Assess Systematic Reviews) instrument, a validated tool used in the critical appraisal of SRs/MAs. RESULTS Of 27 publications met inclusion criteria and were included in the analysis. Mean AMSTAR score (± SD) among all publications was 7.4 (1.9) out of 11, reflecting "fair to good" quality. Non-pharmacological medical treatment for MFI was the most commonly assessed intervention (n = 13, 48.1%). No publications met all AMSTAR criteria. While the number of SRs/MAs has increased over time (P = 0.037), the quality of publications has not significantly changed (P = 0.72). SRs/MAs of the Cochrane Library had higher AMSTAR score than non-Cochrane SRs/MAs (8.5 vs 6.3, P = 0.002). CONCLUSIONS The methodological quality of SRs/MAs should be assessed to ensure high-quality evidence for clinical practice guidelines in MFI treatment and management. This review highlights a need for increased effort to publish high-quality studies in MFI treatment and management.

Abstract
Type V-phosphodiesterase-inhibitors (PDE5i) are the first choice drugs in the treatment of erectile dysfunction (ED), being effective in 60-70% of patients. However, approximately 50% of patients per year discontinue the treatment with PDE5i after reporting poor drug efficacy or major adverse drug reactions (ADR). To identify early markers of efficacy/safety for the treatment of ED with PDE5i, the basal clinical characteristics of patients, integrated with metabolomics analysis of serum and urine and genomic data, were here correlated with the PDE5i efficacy and the occurrence of ADR upon administration. Thirty-six males with new diagnosis of ED were consecutively recruited and characterized at baseline for anthropometrics, blood pressure, blood glucose, lipid profile, serum levels of thyroid/sex hormones and erectile function evaluated by IIEF-15 questionnaire. Targeted Next Generation Sequencing (NGS) was applied to genes involved in PDE5i pharmacodynamics and pharmacokinetics. Fasting metabolic profiles of serum and urine were assessed by nuclear magnetic resonance (NMR)-based metabolomics analysis. Patients were prescribed on-demand therapy with Sildenafil oro-dispersible film and followed-up after 3 months from recruitment. Baseline data were compared with IIEF-15 score at follow-up and with the occurrence of ADR recorded by a dedicated questionnaire. Twenty-eight patients were finally included in the analysis. Serum LDL-cholesterol levels were increased in those reporting ADR (143.3 ± 13.2 mg/dl ADR vs. 133.1 ± 12.4 mg/dl No ADR; p = 0.046). NGS data showed that specific variants of PDE11A and CYP2D7 genes were more represented in drug responders (both relative risk = 2.7 [0.9-5.1]; p = 0.04). NMR-based metabolomics showed the highest association between serum LDL-cholesterol metabolites and the occurrence of ADR (Hazard ratio = 17.5; p = 0.019). The association between lipid profile and the ADR pattern suggests major cues in the tailoring of ED therapy with PDE5i.

Abstract
INTRODUCTION It is predicted that erectile dysfunction will affect around 322 million men worldwide by 2025. Because of the large volume of literature on the topic, physicians often turn to systematic reviews and meta-analyses-and particularly abstracts of such articles-for clinical guidance. Thus, it is crucial that findings are not misrepresented in abstracts. In this study, we evaluated the use of spin (ie, the misreporting of study findings by overstating or selectively reporting efficacy results, minimizing harms, or making unwarranted clinical recommendations) in the abstracts of systematic reviews on erectile dysfunction. METHODS A search strategy was developed using the MEDLINE and Embase databases to retrieve systematic reviews focused on treatments for erectile dysfunction. 2 investigators independently screened the titles and abstracts from the reviews for study inclusion. Investigators analyzed the included systematic reviews for 9 of the most severe types of spin using a previously developed classification scheme and rated them for methodological quality using the revised A MeaSurement Tool to Assess systematic Reviews (AMSTAR) in a masked, duplicate manner. Study characteristics for each review were also extracted in duplicate. RESULTS Our search returned 2,224 articles, of which 102 systematic reviews and meta-analyses were included in the final analysis. A total of 31.4% (32/102) of systematic reviews contained spin. 8 types of spin were identified in our sample. Type 3 (selective reporting of or overemphasis on efficacy outcomes) and type 5 (conclusion claims beneficial effect despite high risk of bias) were the most common types of spin, each occurring in 10.8% (11/102) of abstracts. There was no significant association between the presence of spin and the extracted study characteristics or methodological quality. CONCLUSION Spin was present in systematic reviews and meta-analyses covering erectile dysfunction treatments. Steps should be taken to improve the reporting quality of abstracts on erectile dysfunction treatment. Reddy AK, Lulkovich K, Ottwell R, et al.

Abstract
Contemporary treatment algorithms for erectile dysfunction (ED) involve the use of medical therapies such as phosphodiesterase type 5 (PDE5) inhibitors and intracavernosal injection therapy of vasoactive agents, as well as vacuum erection devices and penile prosthesis implants in medically refractory cases. However, the current therapeutic options only address the symptoms of ED and not the underlying pathogenesis that results in ED. Newer and novel ED therapies aspire to reverse ED conditions by preventing cavernosal fibrosis, promoting endothelial revascularization and modulating various neuro-hormonal pathways. Regenerative therapeutic strategies such as low-intensity shock wave, gene and cellular-based therapies, and penile transplants are designed to improve penile hemodynamics and revitalize the cavernosal smooth muscle to mitigate and/or reverse underlying ED. This state-of-art article evaluates current and emerging therapeutic options for ED.
