Relationship between COVID-19 and Male Sexual Dysfunction; A Prospective, Multicentric Study

Background: Sexual function is an excellent marker of psychological, systemic, and specifically vascular performance. Endothelial dysfunction is the main determinant of coronavirus disease 2019 (COVID-19) symptoms. Considering the adverse effects ofthe COVID-19 pandemic on psychological and sexual functions, we hypothesized potential differences and underlying factors if there is any erectile function and premature ejaculation status of male patients with COVID-19 by comparing both with the control group.Methods: Hospitalized male patients diagnosed with COVID-19 pneumonia were evaluated. Male patients who applied to the Urology outpatient clinic were the control group. All participants completed the International Index of Erectile Function Form 15 (IIEF-15) and gave information regarding their premature ejaculation (PE) status if present. COVID-19 patients were called by phone to fill in the IIEF-15. Their PE status was questioned on the 45th and 90th days after discharge. The following parameters were in the data records: Age, comorbidity, length of hospital stay, treatment, oxygen saturation, pulmonary involvement,white blood cell (WBC), C-reactive protein (CRP), ferritin, fibrinogen, D-dimer, and sedimentation values. Results: The study had 253 participants, including 168 COVID-19 patients and 85 volunteers as the control group. The number of PE cases was less, whereas erectile dysfunction (ED) cases were more in the COVID-19 patient group in comparison to the control group in the pre-pandemic period (p = 0.00) (p = 0.00). In the post-pandemic period, PE developed in 13 more COVID-19 patients on the 45th and 90th days (p = 0.00). The IIEF-15 scores of COVID-19 patients decreased by 4-point in the short term and by 3-point in the long term (p = 0.002). Age and sedimentation were responsible for the difference in PE status.

Novel Marker for Premature Ejaculation: Serum Leptin Level.

BACKGROUND: Leptin, which was only discovered in humans in 1994, has recently been shown to have a possible link with premature ejaculation. AIM: To evaluate whether serum leptin levels differed between patients with premature ejaculation and healthy men, and to analyze the changes in leptin levels before and after treatment. METHODS: Six studies assessing the relationship between leptin and premature ejaculation published up to October 2021 were identified from multiple databases (PubMed, Web of Science, Cochrane) and the data were analyzed by Stata software. OUTCOMES: Differences in leptin levels in premature ejaculation patients and healthy people, and changes of leptin levels in premature ejaculation population before and after treatment. RESULTS: Analysis of studies assessing differences in leptin concentrations between patients with PE and healthy men showed that there was a statistically significant difference in leptin levels between PE patients and controls (WMD (95% CI) = 17.89 (8.64, 27.14), P < .001). On the other hand, the analysis of data from 3 studies describing serum leptin levels in PE patients before and after treatment with selective serotonin reuptake inhibitors (SSRIs) showed that there was a significant decrease with leptin levels in PE patients after treatment (WMD (95%CI) = 22.06 (17.21, 26.92), P < .001). CLINICAL IMPLICATIONS: It is possible that leptin can be used as a new marker for premature ejaculation. STRENGTH & LIMITATIONS: The strength of this study is that it is the first meta- analysis to assess the differences of serum leptin levels between patients with premature ejaculation and healthy subjects and the changes of leptin levels before and after treatment in patients with premature ejaculation. A major limitation is that a greater heterogeneity was identified through our analysis, however we did not find a definitive source of heterogeneity. CONCLUSION: There was a statistically significant relationship between serum leptin levels and patients with PE. In addition, serum leptin levels in patients with PE decreased significantly after 8 weeks of treatment with SSRIs. Liu G, Zhang Y, Zhang W, et al.

[Clinical efficacy of Manlyman Spray on premature ejaculation].

OBJECTIVE: To observe the clinical effect of Manlyman Spray in the treatment of premature ejaculation (PE). METHODS: From January 2021 to March 2022, a total of 123 patients with PE were enrolled in clinical observation. Manlyman Spray was sprayed on the surface of the glans penis, corona of the glans and frenulum of the penis qd for 4 weeks. Before and after medication and at 4 weeks after drug withdrawal, the intravaginal ejaculation latency time (IELT), Premature Ejaculation Diagnostic Tool (PEDT) scores and Chinese Index of Sexual Function for Premature Ejaculation (ClPE) scores of the patients were obtained and compared. RESULTS: Compared with the baseline, the IELT of the patients was significantly prolonged after 4 weeks of medication (ï¼»1.51 ± 0.42ï¼½ vs ï¼»3.79 ± 1.69ï¼½ min, P < 0.05) and at 4 weeks after drug withdrawal (ï¼»1.51 ± 0.42ï¼½ vs ï¼»3.55 ± 1.62ï¼½ min, P < 0.05), the PEDT scores were remarkably improved after 4 weeks of medication (14.0 ± 1.9 vs 7.7 ± 2.1, P < 0.05) and at 4 weeks after drug withdrawal (14.0 ± 1.9 vs 7.8 ± 2.0, P < 0.05), and so were the CIPE scores (9.0 ± 1.6 vs 20.0 ± 1.7, P < 0.05, and 9.0 ± 1.6 vs 17.3 ± 1.6, P < 0.05). CONCLUSION: Manlyman Spray has a definite effect in the treatment of PE.

The number of PE cases was less, whereas erectile dysfunction (ED) cases were more in the COVID-19 patient group in comparison to the control group in the pre-pandemic period (p = 0.00) (p = 0.00). In the post-pandemic period, PE developed in 13 more COVID-19 patients on the 45th and 90th days (p = 0.00). The IIEF-15 scores of COVID-19 patients decreased by 4-point in the short term and by 3-point in the long term (p = 0.002). Age and sedimentation were responsible for the difference in PE status. On the other hand, comorbidity, length of hospital stay, treatment type, WBC, D-dimer, ferritin, CRP levels, and pulmonary infiltration were responsible for the difference in ED. CONCLUSIONS: Based on our findings, we can say that we have enough evidence to suspect COVID-19 sequelae can affect male sexual health. After the pandemic, male patients with andrological problems should have enough time to feel more comfortable and their organic and psychogenic conditions should be optimized.

The Influence of Tramadol on Intravaginal Ejaculatory Latency Time and Sexual Satisfaction Score in Treating Patients With Premature Ejaculation: A Network Meta-Analysis.

This network meta-analysis aimed at assessing the influence of tramadol on the intravaginal ejaculatory latency time (IELT) and sexual satisfaction score (SSS) in treating patients with premature ejaculation (PE). The PubMed, Embase, Cochrane Library databases (until July 2021), and original references of the included articles was systematically retrieved. The PRISMA checklist was followed. Finally, 14 articles including 1971 patients were included in this analysis. The results indicated that patients who were treated with tramadol (50 mg, 62 mg, 89 mg, and 100 mg) were superior to those treated with placebo in terms of IELT (p = .003, p < .00001, p < .00001, and p < .00001, respectively), but 25 mg tramadol did not show a significant advantage (p = .06). Patients who were treated with tramadol (50 mg and 100 mg) had a better efficacy than who were treated with 25 mg tramadol in the IELT (p < .00001 and p < .00001), but the effect of 50 mg tramadol and 100 mg tramadol were not significantly different (p = .17). The tramadol group had the better effect than the placebo group in the SSS (p < .0001). And 50 mg tramadol showed a significant improvement compared with 20 mg paroxetine, as assessed by the IELT (p = .03) and SSS (p = .03). Safety assessments including adverse events suggested that tramadol was well tolerated. Tramadol showed a better improvement of IELT and SSS than placebo or paroxetine, and 50 mg tramadol may be a more reasonable therapeutic dose for patients with PE.

[Correlation of lifelong premature ejaculation with 5-HT system gene polymorphism].

Premature ejaculation is one of the common male sexual dysfunction diseases. Lifelong premature ejaculation (LPE), characterized by an early onset and a long course of disease, has a variety of negative effects on men. The pathogenesis of LPE has not been clarified, but it is believed to be related to the regulation of 5-HT and the 5-HT1a and 5-HT2c receptors from the perspective of the theory of 5-HT system neurotransmitter disorder. Current studies indicate that the 5-HT transporter gene-linked polymorphic region (5-HTTLPR), 5-HT1a receptor gene polymorphism and 5-HT2c receptor gene polymorphism may be associated with the development of and drug effect on LPE. This article reviews the current studies on the development of LPE, effects of medication and 5-HT system gene polymorphism, and discusses the correlation of 5-HT system gene polymorphism with the development of LPE and effects of medication.

Comparison of the efficacy of low-intensity shock wave therapy and its combination with platelet-rich plasma in patients with erectile dysfunction.

We aimed to compare the efficacy of low-intensity shock wave therapy (Li-SWT) alone and its combination with platelet-rich plasma (PRP) in the treatment of patients with erectile dysfunction (ED). Between January 2015 and October 2020, patients who did not benefit from the use of phosphodiesterase type 5 inhibitors (PDE5i; 5 mg/day) for at least 3 months and underwent Li-SWT or Li-SWT with PRP were evaluated retrospectively. There were 93 patients who were subjected to Li-SWT only (Group 1) and 91 patients subjected to Li-SWT with PRP (Group 2). Analysis of the International Index of Erectile Function-Erectile Function Area (IIEF-EF) scores showed a significant increase in both the groups post-treatment (Group 1: from 14.33 ± 4.39 to 23.8 ± 4.37, p = .001; Group 2: from 17.82 ± 3.44 to 26.3 ± 2.55, p = .001). When the increase in the IIEF-EF scores was compared pre- and post-treatment between the groups with respect to the ED grades, there was no statistically significant difference between them. Furthermore, while the intravaginal ejaculatory latency time (IELT) in successfully treated patients of Group 1 remained the same, Group 2 presented 1.5-3.5 times (mean, 2.4) prolongation. Their mean IELT score showed an increase from 2.2 (0.8-3.5) min to 5.3 (2.8-10.5) min. Our study shows that combination treatment of Li-SWT with PRP injections is not only safe for patients with ED, but also effective and safe in prolonging the IELT.

Tolerability and Optimal Therapeutic Dosage of Clomipramine for Premature Ejaculation: A Systematic Review and Meta-Analysis.

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.

Perceptions, Expectations, Preferences, and Attitudes Toward Premature Ejaculation, Its Diagnosis and Topical Treatment with Fortacin™ Spray: Results from an Expert Panel Discussion.

INTRODUCTION: Premature ejaculation (PE) represents the most prevalent male sexual issue. Before beginning treatment, it is essential to discuss the patient's expectations thoroughly. METHODS: Herein, we report the results of an expert panel discussion about perceptions, expectations, preferences, and attitudes towards PE, its diagnosis and treatment. The panel took place in October 2019 and involved 30 Italian urologists experienced in the management of male sexual dysfunction. It aimed at investigating physicians' points of view about selected aspects of PE management which emerged during the counselling of PE patients over the previous two years. Treatment-related questions were mainly focused on topical treatment with Fortacin™. RESULTS: Overall, 83.3% of those interviewed declared that most of their patients perceive PE as a bother rather than a disease. The percentage of urologists interviewed perceived that improved subjective control over ejaculation and prolonged intravaginal ejaculatory latency time (IELT) as the main benefit expected by the majority of their patients was 56.5% and 10%, respectively. Eighty percent of urologists reported on-demand regimen as the dosage modality preferred by the majority of their patients and half of them reported the topical route to be the way of administration preferred in most cases. Moreover, 73.3% of urologists reported that adherence to treatment was higher in patients undergoing topical treatment. Finally, 80% of urologists perceived Fortacin to be efficacious in patients with acquired PE and 70% of them perceived its efficacy to be independent from IELT. DISCUSSION: Most patients perceive PE as a bother rather than a disease and mainly advocate an improved control over ejaculation. Fortacin is perceived as efficacious in patients with acquired PE, and independent from IELT.

Objective and Subjective Measures of Premature Ejaculation: How Closely Do They Correspond and How Well Are the Subjective Measures Recalled?

BACKGROUND: Clinical trials evaluating new treatments for premature ejaculation (PE) should ideally include both objective end points and patient reported outcomes (PROs), but there is no consensus currently over the optimal measures or combination of outcomes. In addition, many PROs use a 1-month recall period, despite concerns about potential recall bias. AIMS: Data from a clinical trial of men with lifelong PE were used to examine the consistency of 2 core items of the Premature Ejaculation Profile (PEP), a widely used PRO for assessing subjective aspects of PE. The specific aim was to assess the level of agreement between the original 1-month recall version compared with a new event-based version of the scale in men meeting current definitions of lifelong PE. A further aim was to investigate the convergent validity between an objective end point of intravaginal ejaculatory latency time (IELT), subjective PEP responses, and a patient's Clinical Global Impression of Change (CGIC) measure. METHODS: For assessment of consistency of PEP responses (short-term [ie, sexual event driven] vs 1-month recall), descriptive statistics, correlation coefficients (Pearson and Spearman), and Bland-Altman plots are presented for each time interval. For assessment of convergent validity, descriptive statistics and correlation coefficients (Pearson and Spearman) are presented for each assessment with geometric mean IELT values. Results are also depicted graphically. Geometric mean IELT over the last 4 weeks of treatment and change from baseline (absolute and fold change) were estimated via a general linear model for each category of change in PEP and CGIC, adjusting for baseline IELT. OUTCOMES: PEP items administered via 1-month recall and short-term event-driven responses gave virtually identical results. There was a strong correlation (very good convergent validity) between IELT and responses to PEP and the CGIC. CLINICAL TRANSLATION: Men with lifelong PE can accurately recall their level of sexual functioning over the previous month. The PEP and CGIC are appropriate instruments to measure the subjective response of men with PE to new treatments. STRENGTHS AND LIMITATIONS: Our analyses address gaps in previously published research on PE assessment methodology. Men with acquired PE, men without partners, and men in homosexual relationships were not studied. CONCLUSIONS: In a clinical trial setting, PEP and CGIC are appropriate end points and are likely the optimal combination of PROs for use with IELT to enable a global assessment of patient response to new PE treatments.

[Injection of botulinum-A toxin into bulbospongiosus muscle for primary premature ejaculation: A preliminary clinical study].

OBJECTIVE: To evaluate the efficacy and safety of injection of botulinum-A toxin into the bulbospongiosus muscle in the treatment of primary premature ejaculation (PPE). METHODS: According to the inclusion criteria, we randomly assigned 70 outpatients with PPE to a trial and a control group of equal number, the former injected with 100 U botulinum-A toxin at 10 U/ml and the latter with the same volume of saline into the bulbospongiosus muscle. Then, we obtained the intravaginal ejaculatory latency time (IELT), scores of the Premature Ejaculation Profile (PEP), Male Sexual Health Questionnaire-Ejaculatory Dysfunction (MSHQ-EjD), and Hospital Anxiety and Depression Scale (HADS), and the incidence of adverse reactions between the two groups before and 4 weeks after treatment. RESULTS: Complete data were obtained from 69 of the patients, 34 in the trial and 35 in the control group. The effectiveness rate was 47.06% (16/34) in the former but 0 in the latter. At 4 weeks after treatment, the patients of the trial group showed a significantly longer IELT than the controls and the baseline (ï¼»2.35 ± 1.83ï¼½ vs ï¼»0.79 ± 0.21ï¼½ and ï¼»0.74 ±+ 0.27ï¼½ min, P < 0.01) and the controls. The patients in the trial group, in comparison with those in the saline control group and the baseline, also exhibited significant improvement in the scores of PEP-ejaculation control (1.21 ± 1.04 vs 0.49 ± 0.56 and 0.47 ± 0.51, P < 0.05), PEP-sexual satisfaction (1.32 ± 1.01 vs 0.71 ± 0.57 and 0.79 ± 0.48, P < 0.05), PEP-PE-related distress (2.12 ± 1.01 vs 2.80 ± 0.68 and 2.76 ± 1.26, P < 0.05), and PEP-PE-induced difficult relationship with the partners (1.38 ± 0.70 vs 2.37 ± 0.55 and 2.12 ± 1.49, P < 0.05). The sexual satisfaction score of the female partners after treatment was markedly improved in the trial group as compared with the control group and the baseline (1.18 ± 1.00 vs 0.57 ± 0.50 and 0.62 ± 0.60, P < 0.05). There were no statistically significant differences in MSHQ-EjD and HADS scores between the two groups before and after treatment. Adverse reactions were observed in 6 cases (17.65%) in the trial group, including 4 cases of decreased erectile hardness (11.76%) and 2 cases of incomplete urination (5.88%), which occurred from the 3 to 4 days after injection, and those with decreased erectile hardness could complete sexual intercourse without any other treatment and recovered after 3 weeks. CONCLUSIONS: Injection of botulinum-A toxin into the bulbospongiosus muscle can be used as an option for the treatment of PPE. Its clinical application value, however, needs to be verified by further studies with larger samples.

Pelvic muscle floor rehabilitation as a therapeutic option in lifelong premature ejaculation: long-term outcomes.

The aim of the study was to evaluate the long-term outcomes of pelvic floor muscle (PFM) rehabilitation in males with lifelong premature ejaculation (PE), using intravaginal ejaculatory latency time (IELT) and the self-report Premature Ejaculation Diagnostic Tool (PEDT) as primary outcomes. A total of 154 participants were retrospectively reviewed in this study, with 122 completing the training protocol. At baseline, all participants had an IELT ≤60 s and PEDT score >11. Participants completed a 12-week program of PFM rehabilitation, including physio-kinesiotherapy treatment, electrostimulation, and biofeedback, with three sessions per week, with 20 min for each component completed at each session. The effectiveness of intervention was evaluated by comparing the change in the geometric mean of IELT and PEDT values, from baseline, at 3, 6, and 12 months during the intervention, and at 24 and 36 months postintervention, using a paired sample 2-tailed t-test, including the associated 95% confidence intervals. Of the 122 participants who completed PFM rehabilitation, 111 gained control of their ejaculation reflex, with a mean IELT of 161.6 s and PEDT score of 2.3 at the 12-week endpoint of the intervention, representing an increase from baseline of 40.4 s and 17.0 scores, respectively, for IELT and PEDT (P < 0.0001). Of the 95 participants who completed the 36-month follow-up, 64% and 56% maintained satisfactory ejaculation control at 24 and 36 months postintervention, respectively.

Premature Ejaculation Among Italian Men: Prevalence and Clinical Correlates From an Observational, Non-Interventional, Cross-Sectional, Epidemiological Study (IPER).

INTRODUCTION: There is a great variability in the prevalence of premature ejaculation (PE) worldwide and only few data are available about the Italian population. AIM: To determine the prevalence of PE in the adult male population in Italy. METHODS: Adult men 18 to 80 years old who were sexually active were randomly sampled from patient lists of general practitioners in Italy and were included in this observational, non-interventional, cross-sectional epidemiologic study from January to July 2015. MAIN OUTCOME MEASURES: Subjects were asked to complete general questionnaires on anthropometric data, lifestyle, education, occupation, economic conditions, general health status, comorbidities, and sexual habits: the Premature Ejaculation Diagnostic Tool (PEDT), the 5-item International Index of Erectile Function, and the Sexual Quality of Life Questionnaire-Male. RESULTS: 1,104 subjects were recruited. Mean age was 45.6 years. Mean prevalence of PE based on PEDT score (≥11) was 18.5%, and 12.4% self-reported an intravaginal ejaculatory latency time shorter than 1 minute. Prevalence of PE proportionally increased with age. 64.6% of patients presented lifelong PE vs 35.4% of patients who reported acquired PE. Estimated prevalence of coexisting PE and erectile dysfunction was 7.0%. Furthermore, overall quality of sexual life was significantly worse in men with PE (P = .006). Enrolled men reported an overall rate of sexual problems in their partners of approximately 30%. 31.3% of patients with PE did not seek help for their dysfunction. No significant differences were noted between patients with and without PE for body mass index, alcohol consumption, smoking habits, physical activity, education, economic conditions, and marital status. CONCLUSIONS: PE has a high prevalence in the Italian male population, increases with age, and heavily affects quality of life in patients and their partners. Encouraging data exist concerning the percentage of patients seeking help for their condition. Verze P, Arcaniolo D, Palmieri A, et al.

Impact of physical activity on patient self-reported outcomes of lifelong premature ejaculation patients: Results of a prospective, randomised, sham-controlled trial.

Previous studies have investigated whether physical activity increases serotonin hormone levels. Serotonin receptor dysfunction is one of the frequently accused factors of premature ejaculation (PE). Nevertheless, no studies up to date have demonstrated that the association between physical activity and premature ejaculation. We aimed to investigate the relationship between physical activity and PE and determine whether moderate physical activity might delay ejaculation time or be an alternative treatment for PE. A total of 105 patients diagnosed with PE were enrolled in this study. Of the patients, 35 were treated with dapoxetine, (30 mg) on demand (Group 1), 35 performed moderate physical activities (Group 2), and 35 performed minimal physical activity (Group 3-sham). Demographic characteristics, metabolic equivalents (MET), premature ejaculation diagnostic tool (PEDT) and intravaginal ejaculatory latency time (IELT) were recorded. There were no significant differences among three groups in terms of age, BMI, MET, PEDT or IELT before treatment. At the end of the study, there was significant decrease in PEDT scores, and increase in IELT in groups 1 and 2 as compared to Group 3. In conclusion, a moderate physical activity longer than 30 min at least 5 times a week leads to ejaculation delay, and appears as an alternative to dapoxetine on demand for the treatment of PE.

Then, we obtained the intravaginal ejaculatory latency time (IELT), scores of the Premature Ejaculation Profile (PEP), Male Sexual Health Questionnaire-Ejaculatory Dysfunction (MSHQ-EjD), and Hospital Anxiety and Depression Scale (HADS), and the incidence of adverse reactions between the two groups before and 4 weeks after treatment.</p><p><b>RESULTS</b>Complete data were obtained from 69 of the patients, 34 in the trial and 35 in the control group. The effectiveness rate was 47.06% (16/34) in the former but 0 in the latter. At 4 weeks after treatment, the patients of the trial group showed a significantly longer IELT than the controls and the baseline (［2.35 ± 1.83］ vs ［0.79 ± 0.21］ and ［0.74 ±+ 0.27］ min, P < 0.01) and the controls. The patients in the trial group, in comparison with those in the saline control group and the baseline, also exhibited significant improvement in the scores of PEP-ejaculation control (1.21 ± 1.04 vs 0.49 ± 0.56 and 0.47 ± 0.51, P < 0.05), PEP-sexual satisfaction (1.32 ± 1.01 vs 0.71 ± 0.57 and 0.79 ± 0.48, P < 0.05), PEP-PE-related distress (2.12 ± 1.01 vs 2.80 ± 0.68 and 2.76 ± 1.26, P < 0.05), and PEP-PE-induced difficult relationship with the partners (1.38 ± 0.70 vs 2.37 ± 0.55 and 2.12 ± 1.49, P < 0.05). The sexual satisfaction score of the female partners after treatment was markedly improved in the trial group as compared with the control group and the baseline (1.18 ± 1.00 vs 0.57 ± 0.50 and 0.62 ± 0.60, P < 0.05). There were no statistically significant differences in MSHQ-EjD and HADS scores between the two groups before and after treatment. Adverse reactions were observed in 6 cases (17.65%) in the trial group, including 4 cases of decreased erectile hardness (11.76%) and 2 cases of incomplete urination (5.88%), which occurred from the 3 to 4 days after injection, and those with decreased erectile hardness could complete sexual intercourse without any other treatment and recovered after 3 weeks.</p><p><b>CONCLUSIONS</b>Injection of botulinum-A toxin into the bulbospongiosus muscle can be used as an option for the treatment of PPE. Its clinical application value, however, needs to be verified by further studies with larger samples.</p>

The prevalence of an excessive prepuce and the effects of distal circumcision on premature ejaculation.

OBJECTIVE: To investigate the prevalence of an excessive prepuce in patients with premature ejaculation (PE) and to evaluate the effectiveness of distal circumcision in reducing the penile hypersensitivity, which is thought to be a cause of PE. PATIENTS AND METHODS: Men were considered to have an excessive prepuce if the foreskin exceeded the external urethral meatus by ≥1 cm in the flaccid state. The diagnosis of PE was based on the Premature Ejaculation Diagnostic Tool (PEDT) questionnaire score and on the intravaginal ejaculatory latency time (IELT). These features were evaluated at baseline and at 6 months after circumcision. RESULTS: Lifelong PE was diagnosed in 352 patients of whom 208 (59.1%) had an excessive prepuce. We offered those with an excessive prepuce a circumcision, as a potential definitive treatment for their PE, and 27 (13%) men accepted. At 6 months after circumcision, there was an increase in the mean (SD) IELT from 40.4 (16.5) to 254 (66.8) s (P < 0.001) and the mean (SD) PEDT score decreased from 17 (2) to 6.6 (1.9) (P < 0.001). Overall, 26 of the 27 (96%) patients that had a circumcision reported an IELT increase. CONCLUSIONS: An excessive prepuce is very common in patients affected by PE. Although accepted by only 13% of our patients, distal circumcision was shown to be a very effective surgical treatment for definitive treatment of PE. We therefore recommend assessing patients complaining of lifelong PE for an excessive prepuce and if they have an excessive prepuce to suggest that they undergo distal circumcision.

Silodosin versus naftopidil in the treatment of premature ejaculation: A prospective multicenter trial.

OBJECTIVES: To determine the efficacy of two α1-adrenoceptor antagonists with different affinities for α1-adrenoceptor subtypes, silodosin and naftopidil, in the treatment of premature ejaculation. METHODS: This was a prospective, open-label, multicenter trial. A total of 26 patients with untreated acquired premature ejaculation were enrolled. Premature ejaculation was defined based on the International Society for Sexual Medicine recommendation. Patients self-administered on demand silodosin 4 mg or naftopidil 25 mg 1 h before intercourse, alternating drugs at least three times each. Clinical global impression change for premature ejaculation, premature ejaculation profile, and intravaginal ejaculation latency time were evaluated at baseline and during treatment. RESULTS: Due to clinical global impression change, 24 patients (92%) and 12 patients (46%) reported improvement in their own premature ejaculation problems under silodosin and nafitopidil administration, respectively. Silodosin treatment produced a significantly higher improvement rate compared with naftopidil (P = 0.0002). Objectively, silodosin significantly prolonged intravaginal ejaculation latency time compared with baseline and naftopidil (P < 0.01). Mean intravaginal ejaculation latency times were 1.9, 4.1, and 7.6 min at baseline, control and with silodosin, respectively. The rate of reduced semen volume during silodosin treatment was higher than during naftopidil treatment. There were no adverse systemic effects in either group. CONCLUSIONS: Silodosin, a highly selective α1A-adrenoceptor antagonist, produces greater improvements in premature ejaculation profiles and related symptoms along with intravaginal ejaculation latency time in acquired premature ejaculation patients with or without erectile dysfunction. This result supports the clinical use of silodosin as an alternative treatment for premature ejaculation.
