Prevalence, lifestyle, and risk factors of erectile dysfunction, premature ejaculation, and low libido in middle-aged men: first results of the Bavarian Men's Health-Study. Andrology 2024; 12:801-808. [PMID: 37676020 DOI: 10.1111/andr.13524] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2023] [Revised: 07/18/2023] [Accepted: 08/28/2023] [Indexed: 09/08/2023]
Abstract
BACKGROUND Erectile dysfunction (ED), premature ejaculation (PE), and low libido (LL) are reported as the most common male sexual dysfunctions. OBJECTIVE To evaluate the prevalence of ED, PE, and LL and associations with lifestyle risk factors and comorbidities in middle-aged men. MATERIALS AND METHODS This study included a population-based random sample of 2500 50-year-old men who completed validated questionnaires, including the International Index of Erectile Function, the Erection Hardness Score, the Sexual Complaints Screener, and further questionnaires. Multiple logistic regression of outcomes ED, PE, and LL was used to model the association with explanatory factors. RESULTS The prevalence of at least one sexual dysfunction was 30%. 21%, 5.2%, and 7.2% of men had ED, PE, and LL, respectively. The risk of ED increased with PE (odds ratio [OR]: 1.94, 95% confidence interval [95%CI]: 1.22-3.08), LL (OR: 2.04, 95%CI: 1.26-3.29), higher waist circumference (OR: 2.23, 95%CI: 1.67-2.96), and lower urinary tract symptoms (LUTS) (OR: 1.88, 95%CI: 1.39-2.55), partnership was associated with a lower risk (OR: 0.57, 95%CI: 0.39-0.85). The risk of PE increased with ED (OR: 1.94, 95%CI: 1.23-3.07), partnership (OR:5.42, 95%CI: 1.30-22.60), depression (OR: 2.37, 95%CI: 1.09-5.14), and LUTS (OR: 2.42, 95%CI: 1.52-3.87), and decreased with physical activity (OR: 0.44, 95%CI: 0.21-0.93). The risk of LL increased with ED (OR: 2.09, 95%CI: 1.31-3.34) and poorer self-rated health (OR: 2.97, 95%CI: 1.54-5.71). DISCUSSION AND CONCLUSIONS Roughly one in three 50-year-old men experience some form of sexual dysfunction and risk factors identified in this study underline the multifactorial nature of ED, PE, and LL. Many risk factors are modifiable which underlines the role of patient education. Modifiable risk factors should be addressed in patient education and men should take active measures to remove the risk posed by these factors.

[PMID: 38553976 DOI: 10.1093/jsxmed/qdae037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 02/12/2024] [Accepted: 02/18/2024] [Indexed: 05/03/2024]
Abstract
BACKGROUND Although premature ejaculation (PE) is the most common male sexual dysfunction, the underlying mechanisms are not fully understood. AIM The study sought to evaluate the possible associations among glans penis volume and tissue stiffness measured using penile ultrasonography and penile shear wave elastography (SWE) with PE. METHODS Men 18 to 65 years of age with normal International Index of Erectile Function scores (>25) and who were diagnosed with PE between June 2021 and June 2022 were enrolled. The Premature Ejaculation Diagnostic Tool score and intravaginal ejaculation latency times were recorded. Healthy volunteers constituted the control group. The study group was divided into lifelong PE (LLPE) and acquired PE (AqPE) subgroups. In all groups, the glans penis volume was measured via penile ultrasonography and tissue stiffness of the glans penis, penile frenulum, postcircumcision mucosal cuff, and penile shaft were measured via SWE. The findings of the groups were compared using appropriate statistical methods. OUTCOMES The outcomes included ultrasonographic and elastographic measurements of the glans penis. RESULTS Data on 140 men, including 70 PE patients and 70 healthy volunteers, were evaluated. Of the patients, 20 had LLPE and 50 had AqPE. The median glans penis volume was significantly greater in the LLPE group (14.1 [range, 6.6-19] mm3) compared with the AqPE group (11.7 [range, 5.1-27] mm3) and control group (11.4 [range, 6.1-32] mm3) (P = .03). According to the Youden index, the best cutoff value for glans penis volume in LLPE compared with non-LLPE (AqPE + control) was 12.65 mm3 (area under the curve, 0.684; 95% confidence interval, 0.556-0.812; P = .009). The risk of having LLPE in those with a glans penis volume ≥12.65 mm3 was 3.326 (95% confidence interval, 1.234-8.965) times higher than the non-LLPE group (P = .014). There were no significant differences between the groups in the SWE evaluation of glans penis, penile frenulum, mucosal cuff, and penile shaft tissue stiffness. CLINICAL IMPLICATIONS The high incidence of PE in those with high glans penis volume may make glans penis volume a predictor for the development of LLPE. STRENGTHS AND LIMITATIONS This was the first study to show that PE is more common in individuals with a high glans penis volume. It was also the first to perform a penile elastographic evaluation in patients with PE. The most important limitation was that we did not evaluate glans penile nerve function with a test, but rather we made an indirect inference about the density of free nerve endings based on increased glans penile volume. CONCLUSION Glans penis volume was a significant predictor for LLPE. However, there are no associations between PE and the glans penis, postcircumcision mucosal cuff, penile frenulum, or penile shaft tissue stiffness and development.

[PMID: 38622269 DOI: 10.1038/s41443-024-00888-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Revised: 03/29/2024] [Accepted: 04/02/2024] [Indexed: 04/17/2024]
Abstract
By observation of Sprague-Dawley male rats with different ejaculatory behaviors, we have identified distinct behavioral characteristics in rapid ejaculator rats. To validate these differential behaviors, we conducted multifaceted behavioral experiments on rapid ejaculator rats and normal rats. Through mating experiments, 42 male rats were categorized into 5 rapid ejaculator rats, 29 normal ejaculator rats, and 8 sluggish ejaculator rats according to their ejaculation frequency. We selected 5 rats exhibiting rapid ejaculation and 5 rats with normal ejaculation for participation in the Morris water maze, open-field test, and balance beam experiments. The open-field tests revealed that rapid ejaculator rats spent shorter time in the center region (1.23 ± 1.21 vs. 6.56 ± 2.40 s, P = 0.0041), less entered the center region (0.80 ± 0.75 vs. 3.40 ± 1.50, time, P = 0.0145), traveled shorter distances (17,003.77 ± 3339.42 vs. 25,037.90 ± 5499.94 mm, P = 0.0371), and had a lower average speed compared with normal rats (66.09 ± 62.36 vs. 195.56 ± 83.41 mm/s, P = 0.0377). However, no significant differences were observed in the Morris water maze and balance beam experiments (0.25 ± 0.05 vs. 0.26 ± 0.07, P = 0.7506;16.40 ± 3.77 vs. 16.25 ± 2.05, P = 0.9515). These behavioral results indicated that the rapid ejaculator rats were more prone to anxiety. To further substantiate this claim, we examined Brain-derived neurotrophic factor expression levels in the hippocampus of rat brains using immunohistochemistry and western blotting. The results demonstrate lower Brain-derived neurotrophic factor expression in the hippocampus of rapid ejaculator rats compared with that in normal rats (P = 0.0093). Thus, our experiments indicate that rapid ejaculator rats exhibit a higher propensity for anxiety, potentially linked to their abnormal neurophysiologic state. It is concluded that rapid ejaculator rats may be more susceptible to anxiety on a pathophysiological basis.

Abstract
PURPOSE To investigate the various strategies used for the treatment of premature ejaculation (PE); these encompassed behavioral, drug and surgical interventions. MATERIALS AND METHODS We retrieved data from electronic literature searches of PubMed and Cochrane library using the MeSH (Medical Subject Headings terms) and text keywords from the earliest available date of indexing through September 2022. The subject headings and text keywords included those related to the population (male patients with PE), interventions & comparisons (mono and combination treatment), and outcomes (ejaculation latency time, ELT). RESULTS The initial search identified a total of 454 articles from electronic databases. Finally, a total of 10,474 patients from 59 direct comparison trials were included 143 effect sizes with 43 treatments. Of these, 9 of mono treatments and 4 of combination treatments were statistically significant. Pharmaceutical agents commonly used for patients with PE are prescribed off-label, except for dapoxetine. The surface under the cumulative ranking curve values of ranking probabilities for each treatment performance, which indicated that tramadol 100 mg ranked first in terms of ELT. CONCLUSIONS Medications recommended by the American Urological Association and the Sexual Medicine Society of North America were all incorporated within the present review, together with additional management approaches that have been evaluated in randomized controlled trials. The findings indicated that in addition to SSRIs, tramadol, clomipramine, topical agents and PDE5 inhibitors could be used in the therapy of PE.

Abstract
INTRODUCTION Premature ejaculation (PE) is a prevalent sexual dysfunction in men that greatly affects their quality of life. In PE, the duration of sexual performance is considered an important aspect. However, a self-estimated value of intravaginal ejaculation latency time (perceived IELT, PIELT) as a criterion for diagnosis has not been specified. AIM This study aimed to determine the validity and a threshold value for PIELT in PE diagnosis. METHOD In our cross-sectional study, we recruited 550 men from March 2019 to January 2020 and interviewed them regarding their general demographic characteristics, sexual habits, PIELT and completed a premature ejaculation diagnostic tool (PEDT) questionnaire. Eventually, a combination of a clinical diagnosis and PEDT score was used, in which those with PEDT ≥ 11 and diagnosed with possible PE were assigned to the final PE(+) group; those with PEDT score ≤ 8 and diagnosed with no PE were included in the final PE(-) group. RESULTS Men PE(-) had more frequent sexual intercourse (9.74 ± 5.38 vs. 6.69 ± 5.38 episodes per month, p < 0.001) and had higher marriage rate (72.7% vs. 60.4%, p = 0.002) than PE(+) patients. No significant difference was noted regarding age, smoking habit, age of first sexual experience, and number of sexual partners between the two groups. The mean PIELT of control subjects and PE(+) patients were 11.69 ± 6.83 min and 2.01 ± 1.21 min, respectively. On receiver operating characteristic curve analysis, the cut-off value of PIELT of 3.75 min can be used to distinguish PE men (area under the curve = 0.982, sensitivity/specificity = 0.961/0.909), which means that men with a PIELT ≤ 3.5 min is suggestive of PE. CONCLUSION The impact of PE is dramatic both from a social and a personal perspective. PE(+) patients married significantly less and have significantly lower sexual activity compared to a PE(-) population. Furthermore, a PIELT of ≤ 3.5 min predicts PE demonstrating the need to revise its taxonomy and definition.

Abstract
This study aimed at assessing a new line of treatment for lifelong premature ejaculation which is botulinum-A toxin injection into the bulbospongiosus muscle. Sixty patients with lifelong premature ejaculation were independently randomized into 2 groups; group I, 100 U botulinum-A toxin at 10 U/ml saline was injected with ultrasound guidance into the bulbospongiosus muscle and group II which was injected with similar volume of saline. The primary outcome was to compare both groups for changes in the Premature Ejaculation Profile (PEP), Intravaginal Ejaculatory Latency Time (IELT) and partner's satisfaction at 1, 3 and 6 months after intervention. The second outcome was to compare the adverse events in both groups. Fifty-seven patients completed the study. In group I, the mean PEP increased significantly at 1- (P = 0.02) and 3- months (P = 0.04) with insignificant increase at 6-month (P = 0.6) of follow-up. Also, no significant changes had been noted in IELT or partner's satisfaction scores throughout the study duration (P > 0.05). In group II, no significant changes had been noted in the PEP, IELT and partner's satisfaction scores throughout the study duration (P > 0.05). There were insignificant differences in the changes in the mean PEP (P = 0.7, 0.6 and 0.4), IELT (P = 0.6,0.6 and 0.5) and partner's satisfaction scores (P = 0.5,0.7 and 0.3) in comparison to the baseline values at 1-, 3- and 6- months, respectively between both groups. Adverse events were observed in only 3 patients (5.3%). In group I, mild erectile dysfunction and post micturition dribbling were reported in one patient each. Where in group II, one patient reported bleeding per urethra (P = 0.5). To conclude, injection of botulinum-A toxin into bulbospongiosus seems to be safe but failed to prove clinical efficacy for treatment of lifelong premature ejaculation when compared to placebo.

Abstract
Disorders of the bulbospongiosus muscle (Bsm) are associated with male sexual dysfunction, such as premature ejaculation. We determined the effect of sucrose-water consumption during pregnancy-lactation and postnatal on reflex responses and morphology of Bsm fibers in adult male Wistar rat offspring. Female rats were mated and grouped into consumed tap water mothers and sucrose-water (5 %) mothers during pregnancy-lactation to obtain experimental groups. Male pups were weaned and assigned into four groups (n = 12; each group). Those from control mothers who continued drinking tap water (CM-CO group) or sucrose water (CM-SO group), and those from sucrose mothers who drank tap water (SM-CO group) or continued drinking sucrose water (SM-SO group) until adult life. In male rat offspring (n = 6 per group) was recorded the electrical activity of Bsm was recorded during penile stimulation and urethrogenital reflex (UGR). Other male rat offspring were designated for histological analysis (n = 6 per group). Sucrose consumption during prenatal stages increased the frequency of the Bsm during UGR, while pre and postnatal consumption modified muscle fiber cross-sectional area and increased the collagen content, suggesting that a combination of a diet with pre- and postnatal sucrose changes the Bsm morphophysiology possibly causing male sexual dysfunctions.

Abstract
Recent research has highlighted structural and functional abnormalities in the cerebral cortex of patients with premature ejaculation (PE). These anomalies could play a pivotal role in the physiological mechanisms underlying PE. This study leveraged functional magnetic resonance imaging (fMRI), a noninvasive technique, to explore these neural mechanisms. We conducted resting-state fMRI scans on 36 PE patients and 22 healthy controls (HC), and collected data on Premature Ejaculation Diagnostic Tool (PEDT) scores and intravaginal ejaculation latency time (IELT). Employing a surface-based regional homogeneity (ReHo) approach, we analyzed local neural synchronous spontaneous activity, diverging from previous studies that utilized a volume-based ReHo method. Areas with significant ReHo differences between PE and HC groups underwent surface-based functional connectivity (FC) analysis. Significant discrepancies in ReHo and FC across the cortical surface were observed in the PE cohort. Notably, PE patients exhibited decreased ReHo in the left triangular inferior frontal gyrus and enhanced ReHo in the right middle frontal gyrus. The latter showed heightened connectivity with the left lingual gyrus and the right orbital superior frontal gyrus. Furthermore, a correlation between ReHo and FC values with PEDT scores and IELT was found in the PE group. Our findings, derived from surface-based fMRI data, underscore specific brain regions linked to the neurobiological underpinnings of PE.

Deger MD, Gül M, Serefoglu EC. Surgical treatment of premature ejaculation: a narrative review. Int J Impot Res 2023:10.1038/s41443-023-00771-9. [PMID: 37798540 DOI: 10.1038/s41443-023-00771-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2023] [Revised: 09/22/2023] [Accepted: 09/25/2023] [Indexed: 10/07/2023]
Abstract
Recurrence after drug cessation is the biggest drawback of medical premature ejaculation (PE) treatments. Although these treatments are demonstrated to be safe and effective, most of the PE patients are interested in a more permanent solution. Despite the fact that currently available guidelines do not recommend surgical treatment for PE, some surgical interventions have been commonly performed for many years, especially in the Asian countries. The main purpose of these surgical treatments is to decrease the sensitivity of the glans penis. However, they are associated with irreversible complications such as penile deformity, sensory loss and erectile dysfunction. The aim of this narrative review is to summarize the advantages and disadvantages of various surgical interventions introduced for the treatment of PE. PubMed, Scopus and Web of Science have been utilized to search articles about glans penis augmentation and penile dorsal nerve interventions. A total of 11 articles were included, three articles excluded because they were in non-English languages. Glans penis augmentation offered a less invasive treatment that avoids severe side effects but requires retreatment in time. Selective dorsal neurectomy provided a more invasive but curative treatment alternative. However, more clinical data are necessary before surgical treatment options can be recommended to patients with PE.

Abstract
Background and Objectives: Ejaculatory dysfunction (EjD) is a common male sexual disorder that includes premature ejaculation, delayed ejaculation, retrograde ejaculation, and anejaculation. Although psychological and pharmacological treatments are available, traditional, complementary, and alternative medicine (TCAM) is reportedly used. However, the clinical evidence for TCAM in EjD remains unclear. Therefore, this study aims to systematically review human clinical trials investigating the use of TCAM to treat EjD. Materials and Methods: A systematic review of the literature following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted by searching Scopus and PubMed databases. Controlled clinical trials investigating a cohort of male patients diagnosed primarily with EjD and undergoing any TCAM intervention compared to any comparison group were included. Quality of the studies was assessed using the Cochrane Risk of Bias tool for randomized controlled trials. Results: Following article screening, 22 articles were included. Of these, 21 investigated TCAM in premature ejaculation, and only 1 investigated TCAM in retrograde ejaculation. Different TCAM categories included studies that investigated lifestyle, exercise and/or physical activities (n = 7); herbal medicine supplements (n = 5); topical herbal applications (n = 4); acupuncture or electroacupuncture (n = 3); vitamin, mineral and/or nutraceutical supplements (n = 1); hyaluronic acid penile injection (n = 1); and music therapy (n = 1). Only 31.8% (n = 7) of the included studies were found to have a low risk of bias. The available studies were widely heterogenous in the TCAM intervention investigated and comparison groups used. However, the included studies generally showed improved outcomes intra-group and when compared to placebo. Conclusions: Different TCAM interventions may have an important role particularly in the management of PE. However, more studies using standardized interventions are needed.

Abstract
Premature ejaculation is the most common male sexual dysfunction, with therapies including selective serotonin reuptake inhibitors, clomipramine, topical anesthetics, dapoxetine and tramadol. However, it is currently unknown how many men are receiving pharmacotherapy for premature ejaculation. Using the TriNetX Research network, a large multicenter database containing over 75 million patient records from hospitals across the United States, we evaluated prescribing patterns for treatment of premature ejaculation and assessed variations in prescription patterns among patients from 2015-2021. In addition, we examined if the prescription patterns for tramadol changed with the establishment of Prescription Drug Monitoring Programs. We found that most men (51.7%) were not receiving any pharmacotherapy for premature ejaculation. However, men with mental health disorders, were more likely (56.0%), to have been treated than those without (44.4%). On further analysis, men with mental health diagnoses were significantly more likely to be treated with Selective Serotonin Reuptake Inhibitors (45.0 vs 32.2%) and Tramadol (5.1% vs 3.5%). While the pharmacotherapy for premature ejaculation has been well researched, our findings revealed that most patients diagnosed with premature ejaculation do not receive pharmacotherapy and that patients are more likely to be prescribed premature ejaculation medications if they have a pre-existing mental health diagnosis.

Abstract
BACKGROUND The aim of this study is to compare the results of stop-start technique with stop-start technique together with sphincter control training applied in the treatment of premature ejaculation. METHODS This research was conducted as a pre-test post-test quasi-experimental study. The sample of the study consisted of 80 men. The study was conducted on men who applied to the urology outpatient clinic of LIV Hospital, a prıvate hospital, in Gaziantep, Turkey, between 01 October 2021 and 01 March 2022. "Personal Information Form", "Intravaginal Ejaculation Latency Time (IELT)", "Fold Increase Intravaginal Ejaculation Latency Time (F-IELT)" "Premature Ejaculation Diagnostic Tool (PEDT) Questionnaire" and "Arabic Index Premature Ejaculation (AIPE)" were used as the data collection tools. Behavioral therapy, consisting of a total of 6 sessions, was applied once every two weeks, with each session lasting for 45 minutes. After 3rd and 6th months from the beginning of the application, the data collection tools were applied again. "Stop-Start Technique (Group A)" and "Stop-Start Technique and Sphincter Control Training (Group B)" were used in the treatment. RESULTS In both groups, the IELT and AIPE values after 3rd and 6th months from the beginning of the application were statistically higher than those obtained before (p<0.05). IELT and AIPE values increased more in Group B than Group A (p<0.05). F-IELT values after 6th months from the beginning of the application were found to be statistically significant with a low level of effect size than those obtained before (p<0.05, Cohen's d = 0.027). In both groups, the PEDT values in the 3rd and 6th months after the application were statistically lower than those seen before (p<0.05). PEDT value decreased more in Group B than Group A (p<0.05). The differences between the two groups' IELT (Cohen's d = 0.011), AIPE (Cohen's d = 0.044), and PEDT (Cohen's d = 0.066) values in the 3rd month after the application and IELT (Cohen's d = 0.025), AIPE (Cohen's d = 0.048), and PEDT (Cohen's d = 0.024) values in the 6th month after the application were found to be clinically weak. CONCLUSIONS It was determined that the stop-start technique given to men with premature ejaculation increased the time spent in the vagina and eliminated the problem of premature ejaculation. It was determined that the stop-start technique in combination with sphincter control training were more effective than the stop-start technique alone.

Abstract
BACKGROUND We investigated the association between premature ejaculation (PE) and the quality of residential environment from a new perspective to explore the influencing factors of PE, especially in four PE subtypes. We selected 499 adult males to participate in this study from September 2021 to September 2022. The satisfaction of residential environment was assessed by the Perceived Residential Environment Quality Indicators (PREQIs) scale, the control ability over ejaculation was assessed using the premature ejaculation diagnostic tool (PEDT), and their depression was assessed using the self-rating depression scale (SDS). RESULTS The Architectural and Town-planning Spaces (ATS), Green Spaces (GS), and Commercial Services (CS) of PE patients (N = 346) were compared with those of control group (N = 153), showed a significant difference (p < .05), for PE patients, the score of ATS was 44.30 ± 12.38, the score of GS was 18.60 ± 6.24, and the score of CS was 20.82 ± 8.20; for control group, which were 40.46 ± 16.21, 20.69 ± 5.71 and 22.90 ± 7.03 respectively. After age was taken into account, ATS had a positive correlation with PEDT score (r = 0.76), whereas GS and CS had a negative correlation (r = -0.87, -0.90); ATS had a positive correlation with SDS (r = 0.96), whereas GS and CS had a negative correlation (r = -0.74, -0.81). CONCLUSIONS We discovered that PE patients more likely resided in high-density areas with little green space and subpar commercial services, which might have an adverse effect on their mental health. This study offered a new viewpoint about the influence of residential environment on PE.

Abstract
Background Premature ejaculation (PE) is a nosologic entity with issues in its conceptualization and definition. Aim To understand if the altered sexual response in men with PE is in the orgasm phase, as currently assumed, or the arousal phase with difficulties in modulating, regulating, or decreasing sexual arousal. Methods Men were recruited who looked for help for PE and met the diagnostic criteria according to clinical standards. The participants completed a sociodemographic survey and the Premature Ejaculation Diagnostic Tool. They also performed a masturbation exercise with a maximum of 5 stops, with the intention of prolonging the arousal phase. The time of the exercise was measured from the beginning of genital masturbation to ejaculation. Outcomes We calculated the total time of the exercise, the median time at each start, and the number of dropouts. We performed a pairwise comparison analysis between starts and made a survival curve representing the percentage of men who remained in the exercise. Results A total of 481 men with PE participated (mean ± SD; age, 29.25 ± 8.72 years). We found that the expected median survival time until ejaculation was 317.00 seconds (95% CI, 288.34-345.65). However, the average time during stimulation decreased as the exercise progressed, and statistically significant differences were observed in their pairwise comparison (P < .001). Also, the chances of ejaculation increased as the exercise progressed, with 62.16% of the participants ejaculating before the end of the exercise. The results indicated increasing sexual arousal, where stops in stimulation were progressively less effective at maintaining ejaculation times at starts. Clinical Implications We showed that the arousal phase is altered in PE, not the orgasm phase, and this could finally have implications in the diagnosis and/or treatment of this condition. Strengths and Limitations The analysis of the times at starts and stops in a masturbation exercise in men with PE, had been barely addressed before. In the future, it would be important to verify the effect of stops during sexual intercourse and to incorporate a control group of men without PE. Conclusions We propose a new conceptualization and definition for PE: progressive arousal disorder is the inability to modulate, regulate, or decrease arousal during any sexual activity, even with brief stops during sexual stimulation, causing unwanted ejaculation.

Premature ejaculation prevalence among young men who have sex with men: a cross-sectional study with internet users in the metropolitan region of São Paulo, Brazil. Sex Med 2023; 11:qfac016. [PMID: 36910706 PMCID: PMC9978591 DOI: 10.1093/sexmed/qfac016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2022] [Revised: 11/18/2022] [Accepted: 11/23/2022] [Indexed: 03/06/2023] Open
Abstract
Background There are only a few studies about the prevalence and correlates of premature ejaculation (PE) among men who have sex with men (MSM). Aim (1) To estimate PE prevalence according to 3 assessment methods: self-reported time from penetration to ejaculation (ejaculation latency time [ELT]); Premature Ejaculation Diagnostic Tool (PEDT); and a direct question about the self-perception of ejaculation as being normal, too early (premature), or retarded. (2) To assess the agreement of the 3 assessment methods and identify factors associated with PE according to each method and their combination. Methods We evaluated data from 226 MSM who participated in a cross-sectional study about sexual behavior among men living in the metropolitan region of São Paulo, Brazil. They responded anonymously to an online survey between May 2019 and March 2020. We calculated the agreement of the 3 assessment methods and their association with other characteristics using logistic regression models. Outcomes Outcomes included the prevalence of PE according to the assessment methods and the association measures (PE vs sociodemographic characteristics and sexual behavior). Results The prevalence of PE among MSM was 21.2% (95% CI, 16.1%-27.1%) according to the PEDT, 17.3% (95% CI, 12.6%-22.8%) per self-report, and 6.2% (95% CI, 3.4%-10.2%) by estimated ELT ≤2 minutes. The agreement among the 3 assessments was fair (kappa, 0.31; 95% CI, 0.25-0.37; P < .001). Association with PE varied by assessment method: obesity and shorter time for ejaculation with anal sex vs masturbation were associated with PE according to the PEDT and ELT but not self-evaluation. Perception about ideal time to ejaculate ≤5 minutes increased the chance of PE based on ELT. Higher chances of self-reported PE were associated with trying to hold back ejaculation, and lower chances were associated with higher frequencies of masturbation. Clinical Implications Combining tools to investigate PE allows the identification of characteristics associated with this condition and may result in improvement in the care of MSM. Strengths and Limitations This anonymous online survey provided the privacy necessary for participants to respond freely about sensitive questions, with a low risk of social adequacy bias. However, as it was a secondary analysis of a larger study, it could not evaluate comorbidities (eg, erectile dysfunction, prostatitis, depression) and the use of condoms. Conclusion The prevalence of PE among MSM is high and varies according to the instrument used for the assessment, and the agreement among the 3 assessments was only fair.

Abstract
BACKGROUND Premature ejaculation (PE) is the most common ejaculatory function disorder. To date, four types of PE have been identified depending on the severity, onset, and course of the problem. OBJECTIVES The aim of this study was to investigate whether or not there is a difference between these types in respect of anxiety, perceived stress, insomnia severity, and sleep chronotype. MATERIALS AND METHODS The study included 112 patients diagnosed with PE in our clinic between October 2021 and May 2022. The patients were separated into groups according to PE types of lifelong (LPE, n = 39), acquired (APE, n = 45), variable (VPE, n = 10), and subjective (SPE, n = 18). In addition to the demographic and clinical data, the scores were recorded of all participants in the International Index of Erectile Function-5, Hospital Anxiety and Depression Scale, Premature Ejaculation Diagnostic Tool (PEDT), Insomnia Severity Index (ISI), Perceived Stress Scale (PSS), and Morningness Eveningness Questionnaire (MEQ). RESULTS SPE was determined more in university graduate patients (42.1% vs. LPE, 21.1%; APE, 36.8%; VPE, 0%; p = 0.01). In patients with APE, erectile dysfunction was more severe (80.0% vs. LPE, 8.0%; SPE, 12.0%; VPE, 0%; p < 0.001). The median (IQR) PEDT score was determined to be higher in APE than in LPE and SPE (16(5), 13(7), 11(5), p = 0.001, respectively). Patients with APE were determined to have higher median (IQR) ISI (21(9) vs. LPE, 8(7); SPE, 5(8); VPE 8(4), p < 0.001) and PSS scores (35(12) vs. LPE, 22 (7); SPE,22(5); VPE 21(6), p < 0.001), the sleep chronotype was more eveningness according to the MEQ (80.8% vs. LPE, 19.2%; VPE, 0%; SPE, 0%; p < 0.001), and there were seen be more anxiety symptoms (75.5% vs. LPE,12.2%; VPE, 0%; SPE, 12.2%; p < 0.001). CONCLUSION Psychological status and sleep health were concluded to be important factors for PE patients, and the patients with acquired PE were the group most affected by these factors.

Abstract
The lack of empirically based diagnostic criteria for delayed ejaculation (DE) not only undermines confidence in the reported prevalence rates for this sexual dysfunction, but it has also resulted in a lack of validated patient reported outcomes (PROs) for assessing this condition. The current study was designed to describe and evaluate six face-valid variables previously shown to discriminate between men with and without DE for their utility as diagnostic measures for DE. A sample of 1285 men (mean age = 37.8, SD = 12.7) free of erectile problems and premature ejaculation completed an online sexual health survey that included potential questions intended for use in the diagnosis of DE. Questionnaire items included ones reflective of previously proposed diagnostic constructs related to DE: ejaculation timing/latency, ejaculation efficacy/control, and negative effects of DE. Results indicated that five of the six proposed items showed moderate intercorrelations, suggesting that each constituted a distinct (i.e., non-redundant) though relevant criterion related to the diagnosis of DE. Based on the level of interrelatedness, the better items representing each construct were included in commonality analysis to assess their unique contributions to the diagnosis of DE. Perceived lack of ejaculatory efficacy/control contributed the largest portion of the variance to the diagnosis of DE (58%), with bother/distress (an index of the negative effects of DE) contributing the second largest portion (25%), and ejaculation timing/latency contributing only a small portion of the variance (6%) to the diagnosis of DE. The relevance of these findings to developing a patient report outcome (PRO) for diagnosing DE that considers both empirically supported questions/items and an appropriate balance of items regarding the three constructs was discussed.

A novel on-demand therapy for lifelong premature ejaculation using a miniature transperineal electrical stimulator-the vPatch: an as-treated analysis. J Sex Med 2023; 20:22-29. [PMID: 36897239 DOI: 10.1093/jsxmed/qdac012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 10/04/2022] [Accepted: 10/09/2022] [Indexed: 01/14/2023]
Abstract
BACKGROUND While premature ejaculation (PE) is a common and disturbing sexual dysfunction in men, current available treatment modalities have limited efficacy and low treatment adherence. AIM To assess the feasibility, safety, and efficacy of the vPatch, a miniaturized on-demand perineal transcutaneous electrical stimulation device for treating PE. METHODS This prospective bicenter international first-in-human clinical study consisted of 2 arms, was sham controlled, and had a randomized double-blind design. In terms of statistical power calculation, 59 patients aged 21 to 56 years (mean ± SD, 39.8 ± 9.28) with lifelong PE were included. During the initial visit, intravaginal ejaculatory latency time (IELT) was measured over a 2-week run-in period. Eligibility was confirmed in visit 2, based on IELT values, medical and sexual history, and patients' individualized sensory and motor activation thresholds during perineal stimulation with the vPatch. Patients were randomized to the active (vPatch) and sham device groups in a 2:1 ratio, respectively. The vPatch device's safety profile was determined by comparing the incidence of treatment-emergent adverse events. During visit 3, IELTs, Clinical Global Impression of Change scores, and Premature Ejaculation Profile questionnaire outcomes were recorded. Primary end points assessed vPatch device efficacy as mean change in geometric mean IELT; each person was compared with himself, with and without the device, and the sham group was compared with the active group. OUTCOMES Outcomes included changes in IELT and Premature Ejaculation Profile before and after treatment, last visit Clinical Global Impression of Change scores, and vPatch safety profile. RESULTS Of 59 patients, 51 completed the study: 34 in the active group and 17 in the sham group. The baseline geometric mean IELT significantly increased from 67 to 123 seconds (P < .01) in the active group, as compared with an insignificant increase from 63 to 81 seconds (P = .17) in the sham group. The increase in mean IELT in the active group was significantly higher than in the sham group (56 vs 18 seconds, P = .01). IELT significantly increased by 3.1 times in the active vs sham group. The mean ratio of fold change (active:sham) was 1.4, significantly different from 1.0 (P = .02). No serious adverse events were reported. CLINICAL IMPLICATIONS Therapeutic use of the vPatch during coitus may become an on-demand, noninvasive, and drug-free treatment for PE. STRENGTHS AND LIMITATIONS To our knowledge, this is the first rigorous study investigating whether transcutaneous electrical stimulation during coitus could improve the symptoms of men with lifelong PE. The study is limited by the small number of patients, the exclusion of patients with acquired PE, the short-term follow up, and the use of a device based on a theoretic mechanism of action. CONCLUSION We demonstrated the possibility to treat lifelong PE by prolonging coitus on demand, using electric stimulation of ejaculation muscles with the vPatch.Clinical trial registration: NCT03942367 (ClinicalTrials.gov).

Abstract
Premature ejaculation (PE) is reported to be the most common sexual dysfunction in men and is defined as the inability to control or delay ejaculation. Steady Freddy is a lidocaine-based ejaculation-delaying spray. This article examines the effects of Steady Freddy on the sexual experience of men that have self-reported to suffer from PE. Under the conditions of a randomized single-blind placebo-controlled clinical trial, 150 participants received either placebo or treatment for the duration of 12 weeks and completed an internet-based questionnaire for the quality of their sexual experience. Prior to product usage, participant average latency time was <1 min, 70% claimed to be very sexually dissatisfied, and 67% claimed to be very dissatisfied with ejaculation control. Upon product usage, sexual experience was significantly improved (p<.01). Participant average latency time increased to >2 min, 80% claimed to be sexually satisfied, and 70% claimed to be satisfied with ejaculation control. These effects were not present in the placebo group throughout the trial. These findings provide evidence for the effectiveness of Steady Freddy in significantly improving the quality of sexual experience and suggest that Steady Freddy can assist with PE.

Abstract
Premature ejaculation (PE) is one of the major causes of sexual dysfunction. Levosulpiride is an off-label medicine used to treat PE, but no review on its efficacy exists. A systematic review and meta-analysis was performed to determine the efficacy of levosulpiride in treating PE. Databases PubMed, Science Direct, and Google Scholar were searched. Randomized control trials (RCTs) comparing levosulpiride with placebo or other medicine were selected. Odds ratio (OR) of improved intravaginal ejaculation latency time (IELT) was calculated. A total of 97 articles were retrieved from database search, of which only four RCTs containing 203 men met the selection criteria. All four RCTs were included in systematic review while only two were included in meta-analysis. A high selection and detection bias was found in both of these studies. Meta-analysis also showed the odds of improving IELT in PE patients using levosulpiride to be significantly higher (p < .05) compared with those who used placebo, OR: 100.81, 95% confidence interval (CI) [13.12-774.90], I2 = 0%. Odds of improving IELT for > 5 min (500% improvement) were also significantly higher (p < .05) compared with the placebo groups (OR: 38.88, 95% CI [5.12-295.29], I2 = 0%). The odds of improving IELT for > 1 min, but < 5 min were also significantly higher (p < .05) than placebo groups (OR: 32.84, 95% CI [4.15-259.75], I2 = 0%). Levosulpiride improved IELT, but even so, limited studies are available on this topic. Additional research is thus required to support the present review's findings.

Abstract
OBJECTIVE: The aim of this study was to evaluate the quality of life of patients with lifelong and acquired premature ejaculation and to examine its relationship with depression and anxiety. METHODS: Between February 2017 and January 2018, a total of 175 patients with premature ejaculation and 132 control men who applied to the urology department of the training and research hospital with the complaint of Premature Ejaculation were included. Patients were divided into three groups according to International Society for Sexual Medicine (ISSM) criteria as follows: Group 1, lifelong premature ejaculation; Group 2, acquired premature ejaculation, and Group 3, control group without premature ejaculation. A detailed medical history of patients was obtained and physical examinations were performed. Intravaginal ejaculation latency time (IELT) was recorded and patients were administered International Erectile Function Index-5 (IIEF-5), Premature Ejaculation Diagnostic Tool (PEDT), Sexual Health Inventory for Men (SHIM), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI)-1 and STAI-2, and Short Form-36 (SF-36). RESULTS: The mean mental component score (MCS) of the SF-36 was 51.65±6.57 in the lifelong premature ejaculation group, 49.33±8.65 in the acquired premature ejaculation group, and 61.12±11.09 in the control group (p<0.0001). The mean physical component score (PCS) was 50.99±7.43 in the lifelong premature ejaculation group, 48.32±11.58 in the acquired premature ejaculation group, and 55.17±8.10 in the control group (p<0.0001). Quality of life of premature ejaculation patients as assessed by SF-36 was lower in the subscales of physical functioning, general health perception, vitality, and role limitations due to emotional functioning, compared to the control group. CONCLUSIONS: Lifelong and acquired premature ejaculation patients deteriorate their quality of life: the deterioration in these patients’ quality of life also negatively affects their depression and anxiety states.

Abstract
PURPOSE Premature ejaculation (PE) is a common sexual dysfunction that significantly affects the quality of life of the patient and their partner. We aimed to compare the efficacy and safety of the combination therapy with biofeedback-guided pelvic floor exercise therapy (BFT) and dapoxetine 30 mg. METHODS Sixty-five patients diagnosed with lifelong PE were included in the study. Patients were divided into three groups as BFT, dapoxetine 30 mg and a combination of BFT and dapoxetine 30 mg. The patients were compared with the intravaginal ejaculatory latency time (IELT) pre-treatment and post-treatment 1st and 3rd months. RESULTS The mean IELTs of the patients in Group 1 were 40 s in pre-treatment, 115 s at the end of the 4th week and 140 s at the end of the 12th week. The IELT values of the patients in Group 2 were 40 s in pre-treatment, 145 s in the 4th week and 170 s in the 12th week. The IELT values were calculated in Group 3 as 42.5 s in pre-treatment, 185 s in the 4th week and 205 s in the 12th week When the IELT was statistically compared between the groups at 1st and 3rd months, the duration in the combination group was found to increase significantly (p < 0.001). CONCLUSION Combination therapy with BFT and dapoxetine 30 mg in lifelong PE treatment is a good alternative with a low side effect profile and acceptable continuous efficiency.

The Tenuous Role of Distress in the Diagnosis of Premature Ejaculation: A Narrative Review. Sex Med 2022; 10:100546. [PMID: 35905650 PMCID: PMC9537272 DOI: 10.1016/j.esxm.2022.100546] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2022] [Revised: 06/22/2022] [Accepted: 06/23/2022] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND Unlike the other 2 criteria for diagnosing premature ejaculation (PE), namely lack of ejaculatory control and short ejaculation latency (EL), the role of bother/distress has received only minimal consideration and investigation. AIM The specific aim was to determine both why distress is included in the PE diagnosis and whether such inclusion is advantageous to achieving better diagnostic outcomes. To this end, the review explored the historical and theoretical underpinnings of the inclusion of "bother/ distress" in the diagnosis of PE, with reference to the larger role that distress has played in the diagnosis of mental disorders, in an attempt to understand the utility (or lack thereof) of this construct in making a PE diagnosis. METHODS We reviewed the role of bother/distress across current professional definitions for PE and then expanded this discussion to include the role of distress in other sexual dysfunctions. We then included a brief historical perspective regarding the role that distress has played in the diagnosis of PE. This discussion is followed by a deeper look at 2 nosological systems, namely DSM and ICD, to allow perspective on the inclusion of the bother/distress construct in the diagnosis of mental and behavioral disorders, including the assumptions/arguments put forward to include or exclude bother/distress as an important criterion underlying various professional assumptions. OUTCOME Determination of the value and/or need of including bother/distress as a necessary criterion for the diagnosis of PE. RESULTS Based on the research literature, bother/distress does not appear to be as critical for a PE diagnosis as either the lack of ejaculatory control or short EL. It is the weakest of the differences among men with and without PE, and recent evidence suggests that its inclusion is generally redundant with the severity of the 2 other criteria for PE, ejaculatory control and EL. CLINICAL TRANSLATION Bother/distress appears to serve little purpose in the diagnosis of PE yet its assessment may be important for the treatment strategy and for assessing treatment effectiveness. STRENGTHS AND LIMITATIONS This review did not provide a critical analysis of the literature regarding the role of bother/distress in PE, but rather focused on its potential value in understanding and diagnosing PE. CONCLUSION Although bother/distress appears to add little to the improvement of accuracy for a PE diagnosis, understanding and assessing the man's or couple's experience of distress has important implications for the treatment strategy and focus, as well as for assessing treatment success.

Abstract
Background: The aim of this study was to analyze the relationship between the prevalence of erectile dysfunction in men as diagnosed by the International Index of Erectile Function (IIEF) questionnaire and the respective levels of sex hormones and biochemical parameters, as well as indices of visceral fat accumulation and activity. Material and Methods: The study comprised 148 male (60–75 years) patients from primary care outpatient clinics in the city of Szczecin (Poland). The men were asked to complete a shortened survey questionnaire with sociodemographic data, as well as a shortened version of the IIEF (five items). Venous blood samples were collected. Total testosterone (TT), estradiol (E2), sex hormone-binding globulin (SHBG), dehydroepiandrosterone sulfate (DHEAS), total cholesterol (ChT), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG), fasting plasma glucose (FPG) and albumin were determined. Lipid accumulation product (LAP) and visceral adiposity index (VAI) were calculated. Results: A correlation was found in the analysis of LAP index values (OR = 1.017; p = 0.050). The analysis of hormone concentrations showed a correlation between the diagnosed trait and the value of TT (OR = 1.216; p = 0.046) and SHBG (OR = 1.020; p = 0.007). Conclusions: VAI and LAP have been shown to be good indicators for assessing erectile dysfunction in men over 60 years of age.

Abstract
PURPOSE To evaluate the clinical characteristics of men presenting for other complaints whose ejaculatory function inquiry indicated premature ejaculation (PE). METHODS The data of 536 PE patients, including those who presented with the complaint of PE (group 1) and those presenting with other complaints who were diagnosed with PE (group 2) as a result of ejaculatory function inquiry using estimated intravaginal ejaculation latency time (IELT) and Premature Ejaculation Diagnostic Tool (PEDT), were retrospectively evaluated. Age, PE type, comorbidities, recommended treatments, and treatment acceptance status of all patients were recorded. These characteristics were compared for each group. RESULTS Among all the patients, those who presented with PE complaints constituted 22.4%. Among the patients with both PE and ED, 98.1% applied with ED complaint and only 1.9% with PE complaint. The percentage of patients with one comorbidity was significantly higher in group 2 (p = 0.032). 90.1% of all patients and 88.5% of patients in group 2 accepted the recommended treatment for PE. The mean age and comorbidities were significantly higher in patients that refused the treatment. The most common reason for treatment refusal was the patients' lack of expectation for treatment. CONCLUSIONS This study shows that men more frequently tend to seek treatment for ED than PE, and treatment acceptance rate may be higher when the patients with PE complaints who don't seek treatment are reached through ejaculatory function inquiry. The presence of comorbidities negatively affects the treatment expectation and acceptance as well as treatment seeking behavior of men with PE.

Abstract
Men with premature ejaculation (PE) during partnered sex (as defined by poor ejaculatory control) show significantly reduced PE symptomology during masturbation, but the reasons for this disparity are not clear. This study investigated the other two PE-related diagnostic criteria, namely ejaculatory latency (EL) and bother/distress, in order to explore possible explanations for this disparity between types of sexual activity. Specifically, 1,447 men with either normal or poor ejaculatory control were compared on EL parameters, bother/distress, and sexual satisfaction/pleasure during both partnered sex and masturbation. Results indicated that men with PE reported longer ELs during masturbation than partnered sex, in contrast with men without PE who reported shorter ELs during masturbation. Bother/distress was lower for both groups during masturbation, but bother/distress in men with PE during masturbation was comparable to that of men without PE during partnered sex. Minimal difference in these patterns was found across lifelong and acquired PE subtypes, whereas men with PE with comorbid erectile dysfunction appeared to represent a distinct group. These findings have implications for PE management or treatment as well as for the overall conceptualization of PE as a pathophysiological condition.

Abstract
Several of the drugs currently available for the treatment of premature ejaculation (PE) (e.g., local anesthetics or antidepressants) are associated with numerous safety concerns and exhibit weak efficacy. To date, no therapeutics for PE have been approved in the United States, highlighting the need to develop novel agents with sufficient efficacy and fewer side effects. In this study, we focused on the histamine H3 receptor (H3R) as a potential target for the treatment of PE and evaluated the effects of imetit (an H3R/H4R agonist), ciproxifan (an H3R antagonist), and JNJ-7777120 (an H4R antagonist) in vivo. Our in vivo electrophysiological experiments revealed that imetit reduced mechanical stimuli-evoked neuronal firing in anesthetized rats. This effect was inhibited by ciproxifan but not by JNJ-7777120. Subsequently, we evaluated the effect of imetit using a copulatory behavior test to assess ejaculation latency (EL) in rats. Imetit prolonged EL, although this effect was inhibited by ciproxifan. These findings indicate that H3R stimulation suppresses mechanical stimuli-evoked neuronal firing in the spinal-penile neurotransmission system, thereby resulting in prolonged EL. To our knowledge, this is the first report to describe the relationship between H3R and PE. Thus, H3R agonists may represent a novel treatment option for PE.

International Continence Society (ICS) report on the terminology for sexual health in men with lower urinary tract (LUT) and pelvic floor (PF) dysfunction. Neurourol Urodyn 2022; 41:140-165. [PMID: 34989425 DOI: 10.1002/nau.24846] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Accepted: 11/22/2021] [Indexed: 12/27/2022]
Abstract
INTRODUCTION The terminology for sexual health in men with lower urinary tract (LUT) and pelvic floor (PF) dysfunction has not been defined and organized into a clinically based consensus terminology report. The aim of this terminology report is to provide a definitional document within this context that will assist clinical practice and research. METHODS This report combines the input of the members of sexual health in men with LUT and PF Dysfunction working group of the International Continence Society (ICS), assisted at intervals by external referees. Appropriate core clinical categories and a sub-classification were developed to give coding to definitions. An extensive process of 18 rounds of internal and external review was involved to exhaustively examine each definition, with decision-making by collective opinion (consensus). The Committee retained evidence-based definitions, identified gaps, and updated or discarded outdated definitions. Expert opinions were used when evidence was insufficient or absent. RESULTS A terminology report for sexual health in men with LUT and PF dysfunction, encompassing 198 (178 NEW) separate definitions, has been developed. It is clinically based with the most common diagnoses defined. Clarity and user-friendliness have been key aims to make it interpretable by practitioners and trainees in all the different speciality groups involved. Conservative and surgical managements are major additions and appropriate figures have been included to supplement and clarify the text. Emerging concepts and measurements, in use in the literature and offering further research potential, but requiring further validation, have been included as an appendix. Interval (5-10 years) review is anticipated to keep the document updated. CONCLUSION A consensus-based terminology report for sexual health in men with LUT and PF dysfunction has been produced to aid clinical practice and research. The definitions that have been adopted are those that are most strongly supported by the literature at this time or are considered clinical principles or consensus of experts' opinions.

Abstract
INTRODUCTION Fifteen years have passed since the International Society of Sexual Medicine first established the 3-pronged criteria for premature ejaculation (PE): a short ejaculation latency, lack of ejaculatory control, and bother/distress. Although the process of establishing valid criteria for any condition or disorder is an ongoing one, a dearth of targeted research on these criteria has hindered professional societies from updating and revising them. OBJECTIVES To review and critique existing criteria used in the diagnosis of PE, to identify specific problems with them, and to recommend studies that will address shortcomings. METHODS Each of the PE criteria was evaluated and compared against standard procedures for establishing validated measures. Following each analysis, targeted research to address the gaps has been recommended. RESULTS Each PE criterion has shortcomings and each can be improved by using standard validation procedures, as noted by the targeted research outcomes. Professional societies can play an important role by encouraging broad participation in research that generates new and relevant data supporting, validating, or challenging the existing criteria. CONCLUSION The concepts underlying the diagnostic criteria for PE have both broad consensus and functional utility. Nevertheless, much of the research investigating PE has uncritically adopted these criteria without concomitantly recognizing their limitations. These limitations prevent determining accurate prevalence rates, interpreting research findings with confidence, and establishing efficacious treatment outcomes. Rowland DL, Althof SE, McMahon CG.

Abstract
PURPOSE To determine the role of poor sleep quality as a risk factor for acquired premature ejaculation (APE) after considering the various risk factors, such as ages, lower urinary tract symptoms (LUTS), anxiety, depression, and erectile dysfunction. METHODS This study presents a multivariate analysis to identify risk factors for PE, including the covariate of age, International Prostate Symptom Score (IPSS), General Anxiety Disorder-7 (GAD-7) score, Patient Health Questionnaire-9 (PHQ-9) score, International Index of Erectile Function (IIEF) score, and Pittsburgh Sleep Quality Index (PSQI). Acquired PE was defined as self-reported intravaginal ejaculation latency time ≤3 minutes, and poor sleep quality was diagnosed using the Pittsburgh Sleep Quality Index tool. RESULTS A total of 349 men were enrolled in the study after completing the questionnaires and the medical history survey. Among 349 men, 203 individuals (58.17%) suffered from acquired PE. The IIEF-5 score, IPSS, GAD-7 score, PHQ-9 score, and PSQI score of the population with PE were significantly different from the non-PE group. Further multivariate analysis showed that erectile dysfunction, depression, severe prostatitis-like symptoms, and poor sleep quality were high-risk factors of APE. Additionally, our study showed that premature ejaculation diagnostic tool (PEDT) score was associated with IPSS/GAD-7/PHQ-9/PSQI scores positively and associated with IIEF-5 scores negatively. The stratified analysis of sleep quality showed that APE patients with different sleep qualities have different prevalence rates of anxiety, depression, prostatitis-like symptoms, and erectile function. CONCLUSION In general, sleep quality may be a potential risk factor for patients with acquired premature ejaculation. Our research revealed the impact of sleep quality on premature ejaculation and provided new viewpoints for further understanding and perfecting the pathogenesis of premature ejaculation.

Abstract
PURPOSE This study aimed to investigate the relationships between intravaginal ejaculatory latency time (IELT), severity of disease, and chronotype in lifelong premature ejaculation (PE). MATERIALS AND METHODS Evaluation was made of 114 males with PE and 103 healthy individuals, and comparisons were made of self-estimated IELT, Arabic Index of Premature Ejaculation (AIPE), Pittsburg Sleep Quality Index (PSQI), and Morningness-Eveningness Questionnaire (MEQ). RESULTS The frequency of morningness chronotype (78.1%) was significantly higher, and Morningness-Eveningness Questionnaire (MEQ) scores were negatively correlated with both IELT (r = -0.490, p < 0.001) and Arabic Index of Premature Ejaculation (AIPE) scores (r = -0.639, p < 0.001) in the PE group. MEQ scores significantly predicted IELT (t = -2.465, p = 0.015) and AIPE scores (t = -4.003, p = 0.000) in the PE group but not in the control group. CONCLUSION It can be asserted that morningness chronotype is more common, and ejaculatory latency time and PE severity are associated with chronotype in males with PE.

Sex Med 2021; 10:100463. [PMID: 34894607 PMCID: PMC8847830 DOI: 10.1016/j.esxm.2021.100463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Revised: 09/25/2021] [Accepted: 10/26/2021] [Indexed: 11/24/2022] Open
Abstract
Background Premature ejaculation (PE) prevalence can vary according to different definitions, assessment methods and populational demographics and culture. Aims To investigate the differences between men classified as having “probable PE” (PEDT≥11), “possible PE” (PEDT = 9 or 10) or “no PE” (PEDT≤8) according to the Premature Ejaculation Diagnostic Tool (PEDT) criteria in regard to sociodemographic characteristics, and sexual and relational behavior. To assess the agreement of prevalence of PE according to 3 assessment methods: (i) the ejaculation latency time (ELT) according to the participant's memory; (ii) PEDT and (iii) a direct question about the self-perception of ejaculation as being normal, too early (premature) or retarded. Methods In this web-based cross-sectional study, men aged ≥ 18 years living in the metropolitan region of São Paulo, Brazil, responded anonymously to an online survey. We used multinomial regression to estimate the association between PE according PEDT criteria and other features and the kappa coefficient to estimate agreement between the assessment methods. Outcomes Association between PEDT-PE, sociodemographic characteristics and sexual and relational behaviors; agreement between PEDT, ELT and self-perception of PE. Results Obesity, trying to hold back ejaculation, short or nonexistent foreplay and age <30 years were associated with PEDT ≥11. Men who considered that latency was shorter for oral, anal and vaginal sex than for masturbation were more likely to have probable PE according to PEDT. Possible PE (PEDT scores 9/10) was associated with trying to hold back ejaculation and considering time for ejaculation shorter for vaginal sex. There was fair agreement between assessments (kappa 0.39; CI:0.28 –0.42; P < .001). Conclusion PE prevalence varies according to instruments and cut-offs used, with fair agreement between them. This finding shows that the methods evaluate different aspects of the EP syndrome and they must be combined to allow the discrimination between the different types of PE and treatments. Clinical approaches should consider the sexual behavior and relationship of the patient and their distress. dos Reis M de MF, Barros EAC, Monteiro L, et al.

Abstract
Lifelong premature ejaculation (LPE) may have heritable components. Selective serotonin reuptake inhibitors have been proven effective in prolonging intravaginal ejaculation latency time (IELT). Given that serotonergic pathways are involved in the ejaculation mechanism, we aimed to investigate whether His452Tyr, also known as the C1354T (RS6314) polymorphism of the 5-HT2A receptor, contributes to LPE pathogenesis and IELT differences among patients with LPE. Dutch Caucasian men with LPE (n = 65) attending the Outpatient Department of Neurosexology, HagaZiekenhuis for drug treatment for LPE in 2009 were selected and included in this case-control study. IELT during coitus was measured using a stopwatch, and all men were genotyped for the His452Tyr polymorphism. Analysis of variance (ANOVA) was performed to determine the association between the genotypes and IELTs. Mean IELTs with standard deviations were 29.7 (±20.9), 31.5 (±14.7), and 26.0 s, and the frequencies were 83.1%, 15.4%, and 1.5% for the CC, CT, and TT groups, respectively, with an average IELT of 29.9 s. No difference in mean IELT was observed between these groups. In the affected group, the frequencies of alleles C and T were 90.8% and 9.2%, respectively; whereas those among randomly selected European Caucasian male controls (n = 503) from the CEPH database were of 92.0% and 8.0%, respectively. No significant difference was observed between the groups. Therefore, no correlation was found between the His452Tyr polymorphism and IELT distribution in patients with LPE.

Abstract
BACKGROUND It is unclear whether men who experience sexual difficulty during partnered sex experience similar difficulty during masturbation. AIM To determine whether sexual functionality and dysfunctionality were similar or different during masturbation vs partnered sex. METHODS We compared sexual responsivity during masturbation vs partnered sex in a multinational sample of 4,209 men with and without a sexual dysfunction to determine whether dysfunctionality was greater, less, or about the same during these 2 types of sexual activity. OUTCOMES Consistently lower impairment of sexual function was found during masturbation compared with partnered sex for all 3 sexual problems assessed: erectile dysfunction, premature ejaculation, and delayed ejaculation. CLINICAL TRANSLATION These findings reiterate the potential value of assessing sexual responsivity during masturbation as well as melding masturbation strategies with couples therapy in order to attenuate impaired response during partnered sex. STRENGTH & LIMITATIONS Although this study provides the first empirical evidence based on a large multinational sample indicating that sexual functionality is consistently higher during masturbation than partnered sex, it does not provide an empirically-derived explanation for this difference. CONCLUSION Understanding a man's response potential during masturbation may be important to improving sexual response during partnered sex, with the need for more targeted research that more directly evaluates the use of such strategies in the treatment of men's sexual problems.

Abstract
Oncosexology is a multidisciplinary field composed of physicians, nurses, psychologists, and other health care professionals focusing on sexual issues in patients with cancer. Although any cancer diagnosis or treatment can be associated with sexual dysfunction, pelvic malignancies (such as prostate, bladder, or colorectal cancer) have the highest rates of sexual dysfunction in men. This includes erectile dysfunction, testosterone deficiency, ejaculatory dysfunction, orgasmic dysfunction, sexual incontinence, and penile shortening. Testicular cancer and hematologic malignancies also have a significant impact on patients' sexual function. Health care providers should address sexual dysfunction with their patients, including any adverse effects of potential treatment options.

Abstract
Premature ejaculation (PE) and delayed/inhibited ejaculation (DE) are 2 ejaculatory problems that may negatively affect the sexual relationship and cause distress. Although no specific cause explains these problems when they have been lifelong conditions, understanding both biological and psychological factors may be relevant to treatment choices, with options ranging from pharmacologic to psychobehavioral. Integrating treatment modalities may lead to better outcomes but may also require greater psychological and resource investment from the patient or couple.

Abstract
Purpose: Neuroimaging has demonstrated altered static functional connectivity in patients with premature ejaculation (PE), while studies examining dynamic changes in spontaneous brain activity in PE patients are still lacking. We aimed to explore the reconfiguration of dynamic functional connectivity (DFC) states in lifelong PE (LPE) patients and to distinguish LPE patients from normal controls (NCs) using a machine learning method based on DFC state features. Methods: Thirty-six LPE patients and 23 NCs were recruited. Resting-state functional magnetic resonance imaging (fMRI) data, the clinical rating scores on the Chinese Index of PE (CIPE), and intravaginal ejaculatory latency time (IELT) were collected from each participant. DFC was calculated by the sliding window approach. Finally, the Lagrangian support vector machine (LSVM) classifier was applied to distinguish LPE patients from NCs using the DFC parameters. Two DFC state metrics (reoccurrence times and transition frequencies) were introduced and we assessed the correlations between DFC state metrics and clinical variables, and the accuracy, sensitivity, and specificity of the LSVM classifier. Results: By k-means clustering, four distinct DFC states were identified. The LPE patients showed an increase in the reoccurrence times for state 3 (p < 0.05, Bonferroni corrected) but a decrease for state 1 (p < 0.05, Bonferroni corrected) compared to the NCs. Moreover, the LPE patients had significantly less frequent transitions between state 1 and state 4 (p < 0.05, uncorrected) while more frequent transitions between state 3 and state 4 (p < 0.05, uncorrected) than the NCs. The reoccurrence times and transition frequencies showed significant associations with the CIPE scores and IELTs. The accuracy, sensitivity, and specificity of the LSVM classifier were 90.35, 87.59, and 85.59%, respectively. Conclusion: LPE patients were more inclined to be in DFC states reinforced intra-network and inter-network connection. These features correlated with clinical syndromes and can classify the LPE patients from NCs. Our results of reconfiguration of DFC states may provide novel insights for the understanding of central etiology underlying LPE, indicate neuroimaging biomarkers for the evaluation of clinical severity of LPE.

Abstract
OBJECTIVE The purpose of this study is to assess the parameters of heart rate variability, which is an indicator of the change in autonomic nervous system (ANS) activity, in individuals with premature ejaculation (PE). MATERIAL AND METHODS This study was performed by comparing 40 patients with PE (mean age, 31.2 ± 4.1 years) and 40 healthy individuals (mean age, 30.4 ± 4.8 years) without PE from May 2018 to December 2019. HRV parameters were compared between men with PE and healthy controls in 24-hour heart rhythm Holter examination. RESULTS In the time domain analysis, which is a subgroup of HRV, square root of differences between consecutive normal NN intervals (RMSSD), which is an indicator of parasympathetic activity, was lower in patients with PE compared with controls (P = .025). Moreover, within the frequency domain analysis, high frequency (HF), another indicator of parasympathetic activity, was lower in patients compared with controls (P = .032). Finally, the LF/HF ratio, reflecting sympathetic/parasympathetic activity ratio, was significantly higher in patients compared with controls (P = .008). Furthermore, the multivariate logistic regression analysis showed that LF/HF ratio is independently associated with PE (P = .005). The ROC curve analysis showed that the optimal cut-off value of LF/HF above 2.7 predicted PE at a sensitivity of 77.5% and specificity of 82.5% (positive predictive value: 81.5% and negative predictive value: 78.5%). CONCLUSION Different HRV parameters were exhibited in the comparison of patients with PE and normal controls. It suggests that the change in HRV parameters will be an indicator of imbalance in ANS and this imbalance may cause PE. Therefore, HRV analysis can be a diagnostic tool to assess altered ANS activity in patients with PE and may be considered as a rapid screening tool.

Abstract
To analyse the current therapeutic options for patients with premature ejaculation (PE) and highlight their mechanism(s) of action, effectiveness, advantages and limitations. A literature search was conducted using the PubMed database searching for articles exploring different PE treatment modalities. A Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) approach was used to report the results of the literature search. A total of 149 articles were included in this review. The currently available treatment methods for PE include behavioural therapy, local anaesthetics, tricyclic antidepressants, selective serotonin reuptake inhibitors, and selective phosphodiesterase inhibitors. Most PE treatments are either experimental or used off-label. New treatments are certainly warranted to overcome this exasperating sexual dysfunction.

Abstract
Objective: To determine the prevalence of premature ejaculation (PE) in Qatar as a representative of the Middle East region and the population perception of normal ejaculation. Subjects and methods: This study was a cross-sectional, observational, non-interventional, epidemiological study, conducted from February 2012 to February 2013. Randomly selected married males were asked to answer two questionnaires in a direct interview. The first questionnaire assessed the PE complaint, the time between ejaculation and intromission (actual intravaginal ejaculatory latency time [IELT-a]), and the perceived normal average time between intromission and ejaculation (IELT-p). The second questionnaire used was the Arabic Index of Premature Ejaculation (AIPE). Results: A total of 3042 subjects were included. The mean (SD) age was 37.09 (9.1) years. The prevalence of PE in Qatar using the self-report and AIPE score was 38.5% and 36.2%, respectively. The median (interquartile range) IELT-a and IELT-p were 5 (3–13.5) and 15 (5–15) min. In the AIPE-confirmed PE group, and according to the AIPE severity classification, the differences in IELT-a and IELT-p between the severity groups were highly significant, with the duration of both IELT-a and ILET-p being higher in AIPE-No-PE and mild-PE groups (P < 0.001 for both). A negative correlation was found between AIPE score and age in the PE group. Conclusion: The prevalence of PE in Qatar is high. PE prevalence was found to increase with age. The IELT and perception of normal IELT were both correlated with the severity of PE.

Abstract
INTRODUCTION Tramadol has been used for the treatment of premature ejaculation, however, the studies published for the same are not well designed. The primary objective of this study was to explore the literature pertaining to the use of tramadol in patients with PE to determine its safety and efficacy in this population. Materials ande methods: Systematic literature search of various electronic databases was conducted to include all the randomized studies and quasi-randomized studies. Standard PRISMA (Preferred reporting Items for Systematic reviews and Meta-analysis) guidelines were pursued for this review and study protocol was registered with PROSPERO (CRD42019123381). RESULTS Out of 9 studies included in this review, 5 were randomized controlled trials, and rests of the 4 studies were quasi-randomized studies. Tramadol resulted in significantly higher improvement of IELT with the mean difference (MD) of 139.6 seconds and confidence interval (CI) 106.5-172.6 seconds with a p-value of p < 0.00001. All dosages except 25mg fared well as compared to placebo. Tramadol fared better than placebo at 1 month, 2 months, and 3 months after initiation of therapy as compared to the placebo. Tramadol group had reported a significantly higher number of adverse events with treatment as compared to placebo but none of them were serious. CONCLUSION Tramadol appears to be an effective drug for the management of PE with a low propensity for serious adverse events. However, evidence obtained from this study is of low to moderate quality. Furthermore, effective dose and duration of therapy remain elusive.

Abstract
PURPOSE Erectile dysfunction (ED) and premature ejaculation (PE) are common sexual disorders in people with diabetes. Glucose variability (GV) has been recognized as a predictor of microvascular complications. The aim of this study was to investigate the relationship between glucose variability and sexual dysfunctions in young men with type 1 diabetes. METHODS One hundred and twelve patients with type 1 diabetes, aged 18-30 years, were enrolled. Patients were divided into two groups according to glucose variability [group 1 (high GV with coefficient of variation ≥ 36%)] and group 2 (low GV with coefficient of variation < 36%)). The presence of sexual dysfunctions was investigated with validated questionnaires. RESULTS ED and PE prevalence rates in group 1 were 26% and 13%, respectively. Similarly, in group 2, the prevalence of ED was 24%, and the prevalence of PE was 13%. In both groups, no significant associations between sexual dysfunctions and parameters of glucose variability were found. Multiple regression analysis identified age and depression as independent predictors of ED and PE. CONCLUSION Young male patients affected by type 1 diabetes with high or low glucose variability show a similar prevalence of sexual dysfunctions. ED is the most common sexual dysfunction in diabetic men. Age and depression were the only independent predictive factors for sexual dysfunctions in this population.

[PMID: 34435970 PMCID: PMC8430863 DOI: 10.2196/30271] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2021] [Revised: 07/05/2021] [Accepted: 07/05/2021] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Premature ejaculation (PE) is one of the most described psychosocial stress and sexual complaints worldwide. Previous investigations have focused predominantly on the prospective identification of cases that meet researchers' specific criteria. The genuine demand from patients with regard to information on PE and related issues may thus be neglected. OBJECTIVE This study aims to examine the online search trend and user demand related to PE on a national and regional scale using the dominant major search engine in mainland China. METHODS The Baidu Index was queried using the PE-related terms for the period of January 2011 to December 2020. The search volume for each term was recorded to analyze the search trend and demographic distributions. For user interest, the demand and trend data were collected and analyzed. RESULTS Of the 36 available PE search keywords, 4 PE searching topics were identified. The Baidu Search Index for each PE topic varied from 46.30% (86,840,487/187,558,154) to 6.40% (12,009,307/187,558,154). The annual percent change (APC) for the complaint topic was 48.80% (P<.001) for 2011 to 2014 and -16.82% (P<.001) for 2014 to 2020. The APC for the inquiry topic was 16.21% (P=.41) for 2011 to 2014 and -11.00% (P<.001) for 2014 to 2020. For the prognosis topic, the annual APC was 11.18% (P<.001) for 2011 to 2017 and -19.86% (P<.001) for 2017 to 2020. For the treatment topic, the annual APC was 14.04% (P<.001) for 2011 to 2016 and -38.83% (P<.001) for 2016 to 2020. The age distribution of those searching for topics related to PE showed that the population aged 20 to 40 years comprised nearly 70% of the total search inquiries (second was 17.95% in the age group younger than 19 years). People from East China made over 50% of the total search queries. CONCLUSIONS The fluctuating online popularity of PE searches reflects the real-time population demands. It may help medical professionals better understand population interest, population concerns, regional variations, and gender differences on a nationwide scale and make disease-specific health care policies. The internet search data could be more reliable when the insufficient and lagging registry data are completed.

Abnormal Functional Connectivity Between the Left Medial Superior Frontal Gyrus and Amygdala Underlying Abnormal Emotion and Premature Ejaculation: A Resting State fMRI Study.

[PMID: 34421524 PMCID: PMC8375680 DOI: 10.3389/fnins.2021.704920] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2021] [Accepted: 06/28/2021] [Indexed: 11/13/2022] Open
Abstract
Introduction Premature ejaculation (PE) is a common sexual dysfunction and is found to be associated with abnormal emotion. The amygdala plays an important role in the processing of emotion. The process of ejaculation is found to be mediated by the frontal-limbic neural circuits. However, the correlations between PE and emotion are still unclear. Methods Resting-state functional magnetic resonance imaging (rs-fMRI) data were acquired in 27 PE patients with stable emotion (SPE), 27 PE patients with abnormal emotion (NPE), and 30 healthy controls (HC). We used rs-fMRI to explore the underlying neural mechanisms in SPE, NPE, and HC by measuring the functional connectivity (FC). Differences of FC values among the three groups were compared when choosing bilateral amygdala as the regions of interest (ROIs). We also explored the correlations between the brain regions showing altered FC values and scores of the premature ejaculation diagnostic tool (PEDT)/Eysenck Personality Inventory about neuroticism (EPQ-N) in the PE group. Results When the left amygdala was chosen as the ROI, the SPE group exhibited an increased FC between the left medial superior frontal gyrus (SFGmed) and amygdala compared with the NPE or HC group. When the right amygdala was chosen as the ROI, the NPE group exhibited a decreased FC between the left SFGmed and right amygdala compared with the HC group. In addition, FC values of the left SFGmed had positive correlations with PEDT and negative correlations with EPQ-N scores in the PE group. Moreover, FC values of the left superior temporal gyrus had positive correlations with EPQ-N scores in the PE group. Conclusion The increased FC values between the left SFGmed and amygdala could reflect a compensatory cortical control mechanism with the effect of stabilized emotion in the limbic regions of PE patients. Abnormal FC between these brain regions could play a critical role in the physiopathology of PE and could help us in dividing PE into more subtypes.

Abstract
Psychological account hypothesizes that premature ejaculation (PE) is a learned pattern of rapid ejaculation maintained by anxiety about sexual failure, whereas neuropsychological accounts hypothesizes that PE is the result of dysfunction of central nervous system regulating ejaculatory. However, the central neural mechanism underlying PE patients with anxiety remains unclear. Resting-state functional magnetic resonance imaging (fMRI) data were collected in 20 PE (diagnoses based on PE Guidelines drafted by the International Society for Sexual Medicine [ISSM]) patients with anxiety and 25 matched healthy controls (HCs) from January 2019 to December 2020. The values of fractional amplitude of low-frequency fluctuation (fALFF) were compared between groups. Moreover, the correlations between fALFF and the severity of PE and anxiety of patients were examined. PE patients with anxiety had increased fALFF values in the right inferior frontal gyrus (opercular part) and middle frontal gyrus. In addition, significant positive correlations were found between the scores of PE diagnostic tool (PEDT) and fALFF values of the right inferior frontal gyrus (opercular part), as well as the right middle frontal gyrus. Moreover, fALFF values of the right inferior frontal gyrus (opercular part) and middle frontal gyrus were positively correlated with the scores of self-rating anxiety scale (SAS). Our results suggested that increased attentional network activity might play a critical role in the neural basis of PE patients with anxiety.

Abstract
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.
