INTRODUCTION
Previous studies have shown a strong association between diabetes mellitus (DM) and the frequency and severity of some aspects of male sexual dysfunction (SD). The same relationship with prediabetes (preDM) has been less well investigated.
AIM
To systematically review the current literature on the association between preDM and SD, focusing on erectile dysfunction (ED), sex steroid hormone alterations, and premature ejaculation (PE).
METHODS
The present review was conducted in accordance with the PRISMA declaration standards for systematic reviews. A systematic search for the terms "male sexual dysfunction," "prediabetes," "IFG or IGT," "glycemia," "ED," "ejaculation," and "hypoactive sexual desire disorder" was carried out in the PubMed and Embase databases.
MAIN OUTCOME MEASURE
Prevalence of SD in men with preDM and severity of ED, PE, and hormone alterations in men with preDM compared with controls.
RESULTS
12 studies reporting data on the association between SD and preDM were found in the literature. According to these studies, ED is more prevalent in men with preDM compared with controls, the severity of ED increases progressively as a function of impaired glucose metabolism, testosterone values and preDM are strongly correlated, men with preDM are at increased risk of testosterone deficiency and hypogonadism, men with hypogonadism have a higher prevalence of preDM, and the association between PE and preDM is controversial.
CONCLUSION
PreDM is a common and underdiagnosed clinical condition that is strongly associated with male SD. A detailed glucose metabolism investigation should be performed in every patient with SD to screen for glucose abnormalities and eventually to implement prevention program to decrease their chances of developing life-changing chronic illnesses.

Review
INTRODUCTION
Clomipramine is effective in treating premature ejaculation, a common form of male sexual dysfunction that affects individual's mental health and quality of life, but its optimal dosage remains controversial.
AIM
In this systematic review and meta-analysis, we aimed to evaluate the efficacy, safety, and optimal dose of clomipramine for treating premature ejaculation among men.
METHODS
Eligible studies of PubMed, Embase, and Web of Science were identified from the date of inception to June 21, 2020. We conducted the study according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data of the study characteristics, intravaginal latency ejaculatory time (IELT), adverse events, success rate, and satisfaction rate of clomipramine vs placebo were extracted and analyzed. The risk ratio and mean difference were used for quantitatively analyzing binary outcomes and continuous outcomes. The standardized mean difference was applied to the outcome of satisfaction rate. The Mantel-Haenszel method was used for meta-analysis under random-effects model. To assess dose effect of clomipramine, a meta-regression analysis was performed.
MAIN OUTCOME MEASURES
The primary outcomes were the IELT and adverse events, and the secondary outcomes were the success rate and satisfaction rate of clomipramine treatment relative to the placebo.
RESULTS
A total 14 randomized controlled trials with 710 patients were included for quantitative analysis. Clomipramine significantly increased the IELT compared with the placebo (mean difference: 1.47, 95% CI: 0.73-2.21). However, clomipramine was associated with higher risks of overall adverse events and adverse events in the nervous and respiratory systems. Significant dosage effects on the IELT (estimate: 0.0637, 95% CI: 0.0074-0.12) and a slightly increasing slope on adverse events were revealed.
CONCLUSION
Clomipramine increased the IELT and yielded greater satisfaction than the placebo, and the higher dose results in a superior IELT without leading to higher risk of adverse events under a dosage of 50-mg clomipramine.

Meta-Analysis Review
Premature ejaculation (PE) represents a common sexual dysfunction and is associated with a negative impact on quality of life and relationships. Recent evidence suggests that on-demand dosing of tramadol is effective at increasing intra-vaginal ejaculatory latency time (IELT) and improving subjective measures of satisfaction. A literature review was performed of journal articles published between January 2000 and July 2014 that matched the keywords 'tramadol' and 'premature ejaculation'. We identified eight relevant articles with the criteria that each article be published in a peer-reviewed journal, represent original work and be written in English. IELT was used as the primary outcome in each of the papers reviewed for efficacy. Additional subjective outcome measures were reviewed where available. Safety was assessed using adverse event data from the individual studies. We found that tramadol in on-demand dosing is effective at lengthening IELT in men with varying degrees of PE and improves patient satisfaction. Tramadol was generally well tolerated, particularly among those taking 25 and 50 mg doses. Although there is a risk of abuse and dependence, these events are rare, particularly at low doses taken intermittently. In conclusion, tramadol is an effective oral therapy for PE that is overall safe and well tolerated.

Meta-Analysis
The purpose of this analysis is to assess the efficacy and safety of phosphodiesterase-5 inhibitors (PDE5Is) for the treatment of premature ejaculation (PE). A comprehensive search was performed to ascertain from trials about PDE5Is for the treatment of PE and compare the results, including intravaginal ejaculatory latency time (IVELT), score of sexual satisfaction scale, and side effects, between the group treated with PDE5Is and that treated with placebo. Seven studies involving a total of 471 patients were included in this meta-analysis. This analysis showed that patients who were treated with PDE5Is had significantly increased IVELT (mean difference [MD] 2.60; 95% CI [1.85, 3.36]; < .00001) and score of sexual satisfaction scale (MD 2.04; 95% CI [0.78, 3.30]; = .002) compared with the group on placebo. More patients had side effects while taking PDE5Is, such as headache, dizziness, flushing, and nasal congestion. PDE5Is were significantly more effective than placebo in the treatment of PE. Side effects were more common among patients who were treated with PDE5Is.

Meta-Analysis
BACKGROUND
Paroxetine is one of the selective serotonin reuptake inhibitors (SSRIs) used in the treatment of premature ejaculation (PE). However, this use is not approved in many countries. The purpose of this systematic review and meta-analysis is to review the efficacy and safety of paroxetine for PE patients.
METHODS
We searched relevant randomized, controlled trials through May 2018, using PubMed, Embase and Cochrane Central Register. The main endpoint included intra-vaginal ejaculatory latency time (IELT) and side effects in the treatment of PE. Cochrane Collaboration's Revman software, version 5.3, was used for statistical analysis.
RESULTS
Out of 493 unique articles, a total of 19 randomized, controlled trials (RCTs) were reviewed. Quite a few RCTs were considered to have unclear risk of bias because of limited information. Pooled outcomes suggested that paroxetine was more effective than placebo, fluoxetine and escitalopram at increasing IELT (all p < 0.05). However, there existed a high level of heterogeneity in the paroxetine vs. fluoxetine groups and the paroxetine vs. placebo groups. Comparing paroxetine with tramadol, sertraline, phosphodiesterase 5 inhibitors (PDE5Is), local lidocaine gel, behaviour therapy or dapoxetine, we found that the increase in IELT was not statistically significant between groups. Paroxetine combined with tadalafil or behaviour therapy was more efficacious than paroxetine alone (all p < 0.05). Although the side effects in the combination group were more common than in the paroxetine alone group, the most common adverse events, such as nausea, muscle soreness, palpitation and flushing, were mild and tolerable. The main limitations of this systematic review and meta-analysis were the different definitions of PE and short follow-up times.
CONCLUSIONS
According to this systematic review and meta-analysis, paroxetine provided better efficacy than placebo, fluoxetine and escitalopram in the treatment of PE, with well-tolerated side effects. The combination group had better efficacy than the paroxetine alone group.

Lower urinary tract symptoms (LUTS) refer to a group of symptoms related to bladder, prostate, and urethra. LUTS are common in men and the severity increases with age. LUTS are frequently associated with sexual dysfunction, such as premature ejaculation (PE), standing as the most common sexual dysfunction in men. Both LUTS and PE cause distress and dissatisfaction for the patient and his partner. This systematic review aims to determine the relationship between LUTS and PE in men. Two reviewers independently conduct a literature search in five online databases (PubMed, Scopus, Proquest, ClinicalKey, and ScienceDirect). In addition, reviewers also reviewed the reference list of chosen articles to identify additional relevant studies. Twelve articles were included in this systematic review that consists of one cohort study and 11 cross-sectional studies. The total scores of each identified study ranged from "poor" to "good." The prevalence of PE in LUTS ranged from 12 to 77%. Most of the studies showed a significant relationship between LUTS and PE. PE is more common in older age with the peak prevalence in age of 60-69 years old. There is a possible association between PE and LUTS. Further research using cohort or case-control study design on this topic is needed.

Meta-Analysis
BACKGROUND
Premature ejaculation is a form of male sexual dysfunction. As people's lifestyle changes and the population ages, the incidence of premature ejaculation continues to increase. Many clinical trials have proven that Chinese medicine has a significant effect in the treatment of premature ejaculation. In this systematic review, we aim to evaluate the effectiveness and safety of Traditional Chinese medicine for premature ejaculation.
METHODS
We will search for PubMed, Cochrane Library, AMED, EMbase, WorldSciNet; Nature, Science online and China Journal Full-text Database (CNKI), China Biomedical Literature CD-ROM Database (CBM), and related randomized controlled trials included in the China Resources Database. The time is limited from the construction of the library to April 2019. We will use the criteria provided by Cochrane 5.1.0 for quality assessment and risk assessment of the included studies, and use the Revman 5.3 and Stata13.0 software for meta-analysis of the effectiveness, recurrence rate, and symptom scores of premature ejaculation.
ETHICS AND DISSEMINATION
This systematic review will evaluate the efficacy and safety of Traditional Chinese medicine for treating premature ejaculation. Because all of the data used in this systematic review and meta-analysis has been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process Trial.

Review
PURPOSE
To clarify the efficacy of phosphodiesterase-5 inhibitors (PDE5Is) and selective serotonin reuptake inhibitors (SSRIs) in men with premature ejaculation (PE).
METHODS
We searched the PubMed, Embase, and Cochrane Library databases to identify all randomized, controlled trials (RCTs) and compared the results, including intravaginal ejaculation latency time, satisfaction, intercourse per-week and side effects after treatment with PDE5I or SSRIs versus placebo, combined use of PDE5I with SSRIs versus PDE5I or SSRIs alone, and PDE5I versus SSRIs for treating PE.
RESULTS
The study inclusion criteria were met by 23 studies (ten RCTs with five crossover studies) involving 6145 patients. The data synthesized from these studies indicated that the efficacy of PDE5Is and SSRIs was better than that of placebo (p < 0.00001; p < 0.00001); however, more patients had side effects while taking PDE5Is and SSRIs (p < 0.00001; p < 0.00001). The efficacy of the combined treatment was significantly better than that of PDE5Is or SSRIs alone (p < 0.00001; p < 0.00001); however, more patients had side effects from the combined treatment than from SSRIs (p = 0.0002), with no significant difference in PDE5Is (p = 0.5). The efficacy of PDE5Is was better than that of SSRIs (p = 0.006), and no significant difference was observed in the frequency of side effects (p = 0.93).
CONCLUSIONS
PDE5Is were significantly more effective than placebo or SSRIs for treating PE, while SSRIs were better than placebo. The combined treatment had better efficacy than PDE5Is or SSRIs alone.

Meta-Analysis
CONTEXT
Phosphodiesterase type 5 inhibitors (PDE5-Is) are prescribed off-label for the treatment of premature ejaculation (PE).
OBJECTIVE
To systematically review the evidence from randomised controlled trials (RCTs) for PDE5-Is in the management of PE.
EVIDENCE ACQUISITION
Medline and other databases were searched through September 2015. Quality of RCTs was assessed. Intravaginal ejaculatory latency time (IELT) data were pooled in a meta-analysis. Heterogeneity was assessed.
EVIDENCE SYNTHESIS
Fifteen RCTs were included. The majority were of unclear methodological quality. Pooled IELT evidence suggests that PDE5-Is are significantly more effective than placebo (231 participants, p<0.00001), that there is no difference between PDE5-Is and selective serotonin reuptake inhibitors (SSRIs; 405 participants, p=0.50), and that PDE5-Is combined with an SSRI are significantly more effective than SSRIs alone (521 participants, p=0.001); however, high levels of statistical heterogeneity are evident (I ≥ 40%). Single-RCT evidence suggests that sildenafil is significantly more effective than the squeeze technique, but both lidocaine gel and tramadol are significantly more effective than sildenafil. Sildenafil combined with behavioural therapy is significantly more effective than behavioural therapy alone. Sexual satisfaction and ejaculatory control appear to be better with PDE5-Is compared with placebo and with PDE5-Is combined with an SSRI compared with an SSRI alone. Adverse events are reported with both PDE5-Is and other agents.
CONCLUSIONS
PDE5-Is are significantly more effective than placebo and PDE5-Is combined with an SSRI are significantly more effective than SSRIs alone at increasing IELT and improving other effectiveness outcomes; however, heterogeneity is evident across RCTs. The methodological quality of the majority of RCTs is unclear.
PATIENT SUMMARY
We reviewed phosphodiesterase type 5 inhibitors (PDE5-Is) for treating premature ejaculation. We found evidence to suggest that PDE5-Is are effective compared with placebo and that PDE5-Is combined with an SSRI are more effective than an SSRI alone. Adverse events are reported with PDE5-Is and other agents; however, the quality of the evidence is uncertain.

Meta-Analysis
We conducted a systematic review and meta-analysis of published randomised controlled trials of dapoxetine for premature ejaculation. We systematically searched Embase, PubMed, Cochrane, Web of Knowledge, FDA.gov and Clinical Trials.gov for studies reporting dapoxetine in men with premature ejaculation. Efficacy endpoints included intravaginal ejaculatory latency times (IELT), personal distress related to ejaculation (PDRE) and treatment-emergent adverse events (TEAEs) was used to evaluate safety. Data were analysed using a random-effects model. Electronic search identified 276 papers. The final analysis included eight papers (n = 8422 subjects). Analysis of the pooled results indicated efficacy in both IELT (weighted mean difference (WMD) = 1.67, 95% confidence interval (CI) 1.45-1.89) and PDRE (relative risk = 1.26, 95% CI 1.18-1.35). Subgroup analysis indicated efficacy (i.e. increase in IELT) for 30- and 60-mg on-demand dapoxetine (WMD 1.38 (95% CI 1.01-1.75) and 1.62 (95% CI 1.40-1.84) respectively), as well as daily use of 60 mg dapoxetine (WMD 2.18, 95% CI 1.71-2.64). The safety profile was acceptable. Based on the different effects of magnitude of the three dosing regimens, we recommend a stepwise approach, starting with 30 mg on demand, then 60 mg on demand and finally 60 mg dapoxetine daily.
