Huyghe E, Grellet L, Faix A, Almont T, Cuzin B, Burte C. Recommendations for the diagnosis and evaluation of premature ejaculation. THE FRENCH JOURNAL OF UROLOGY 2024; 34:102697. [PMID: 39002734 DOI: 10.1016/j.fjurol.2024.102697] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/28/2024] [Revised: 06/25/2024] [Accepted: 07/05/2024] [Indexed: 07/15/2024]
Abstract
OBJECTIVES The Association Interdisciplinaire Post-Universitaire de Sexologie (AIUS) has brought together a panel of experts to draw up French recommendations for the management of premature ejaculation. This article presents the recommendations for the diagnosis and evaluation of premature ejaculation. METHODS Systematic review of the literature between 01/1995 and 02/2022. Using the method of recommendations for clinical practice (RPC). RESULTS We recommend using the SIAMS definition for everyday clinical practice. PE is defined as: (i) a persistent and recurrent subjective perception of loss of control (management) of the ejaculatory mechanism in the presence of appropriate erotic stimuli; (ii) subjective, PE-related distress induced in the patient and sexual dissatisfaction or PE-related anorgamy in the partner; (iii) a short intravaginal ejaculatory latency time, whether subjectively perceived by the patient and the partner or objectively measured as less than 180seconds (generally). We suggest that the same definition be applied to practices other than vaginal penetration, such as masturbation, oral or anal intercourse, as well as to non-heterosexual contexts. We suggest using information reported by the patient, possibly supplemented by assessment tests/questionnaires (IPE, PEP, PEDT). We recommend investigating the presence of other sexual dysfunctions, in particular erectile dysfunction (ED), as well as any sexual dysfunctions of partners. We recommend taking a medical and psychosexological history, and carrying out a targeted physical examination in patients complaining of PE. CONCLUSION These recommendations should help to improve the management of PE.

Abstract
Tarlov cysts adjacent to the spinal cord are usually asymptomatic and found incidentally via magnetic resonance imaging. On rare occasions, they increase in size to produce symptoms resembling disk herniation. We report a rare case of a sacral cyst resulting in premature ejaculation in a 32-year-old man who presented with pelvic pain and acquired premature ejaculation. Spinal nerve root decompression, excision of intraspinal Tarlov cyst, and spinal nerve root adhesion release surgery significantly improved his pain and premature ejaculation at a six-month follow-up.

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
Given that sexual behavior is usually pleasurable and highly rewarding, it is surprising that there is as yet no known research to empirically assess how premature ejaculation (PE) patients respond to the rewarding aspect of sexual behavior. This study was designed to address this issue by evaluating how these men respond to the anticipation and hedonic experience of sexual rewards in comparison to non-sexual rewards. Thirty lifelong PE patients and thirty healthy controls (HCs) performed the incentive delay task manipulating both erotic and monetary rewards. Compared to HCs, lifelong PE patients exhibited significantly faster RTs to erotic cues than to monetary cues during reward anticipation. Meanwhile, hedonic experience ratings after obtaining the actual reward showed that erotic rewards were rated as more pleasant than monetary rewards only by lifelong PE patients, which was driven by a decreased sensitivity to experienced monetary rewards in lifelong PE patients compared to HCs. These findings indicate the existence of dysfunctional reward processing in lifelong PE patients, which is characterized by increased incentive motivation elicited by sexual cues and reduced hedonic impact of nonsexual rewards. This study may offer an insightful clue regarding how PE is related to the abnormal regulation of the rewarding aspect of sexual behavior.

Premature ejaculation among men with erectile dysfunction-findings from a real-life cross-sectional study. Int J Impot Res 2023; 35:558-563. [PMID: 35915329 DOI: 10.1038/s41443-022-00601-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Revised: 07/08/2022] [Accepted: 07/12/2022] [Indexed: 01/23/2023]
Abstract
Concomitant sexual disorders have progressively shown increased prevalence in men at first outpatient presentation. We sought to i) estimate the prevalence of unreported premature ejaculation (PE) in a homogenous cohort of 1258 men seeking first medical help for erectile dysfunction (ED) as their primary compliant; ii) compare the baseline sociodemographic and clinical characteristics of men with only ED(ED-only) compared to those with ED and PE(ED + PE); and, iii) investigate the likelihood of detecting PE among men self-reporting only ED over a 16-year period at a single tertiary-referral centre. Descriptive statistics compared sociodemographic and clinical characteristics between ED-only patients and those with unreported concomitant primary/secondary PE(ED + PE). Logistic regression models predicted the risk of having ED + PE at baseline. Local polynomial regression models graphically explored the probability of reporting PE among ED men with ≤40 vs. 41-60 vs. >60 years over the analysed timeframe. Of all, 932 (74.1%) were ED-only and 326 (25.9%) ED + PE patients, respectively. ED + PE patients were younger, presented with fewer comorbidities, and lower rates of severe ED (all p ≤ 0.04). At multivariable logistic regression analysis, younger age (OR:0.98) and low sexual desire/interest (OR:1.54) were independently associated with ED + PE at first clinical assessment (all p = 0.03). The likelihood of detecting unreported concomitant primary/secondary PE among patients complaining of only ED at first presentation worrisomely increased among younger and middle-aged men over the last 16 years.

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.

Abstract
OBJECTIVE This study aimed to investigate the effect of penile selective dorsal neurectomy (SDN) on erectile function in rats. METHODS Twelve adult male Sprague-Dawley rats (15 weeks old) were divided into three groups (n=4 per group): in control group, rats received no treatment; in sham group, rats underwent a sham operation; in SDN group, rats underwent SDN with half of the dorsal penile nerve severed. The mating test was performed, and the intracavernous pressure (ICP) assessed six weeks after the surgical treatment. RESULTS At postoperative six weeks, the mating test revealed no significant difference in mounting latency and mounting frequency among the three groups (P>0.05), while the ejaculation latency (EL) was significantly longer and ejaculation frequency (EF) lower in the SDN group than in the control and sham groups (P<0.05). There were no significant differences in preoperative and postoperative ICP and ICP/mean arterial blood pressure (MAP) among the three groups (P>0.05). CONCLUSION SDN does not adversely affect the erectile function and sexual desire of rats, and at the same time it can reduce EL and EF, providing an application basis for SDN in the clinical treatment of premature ejaculation.

Abstract
Objective To assess safety and efficacy of hyaluronic acid (HA) gel injection in glans penis for treatment of premature ejaculation (PE) using our new five puncture technique. Patients and methods This is a prospective, non-randomized clinical trial on HA gel injection in glans penis for all patients with lifelong PE; all patients were circumcised having heterosexual normal marital life and sexually active. Patients with history of ejaculatory medication use within the previous 3 months, psychiatric disorders, erectile dysfunction, lower urinary tract symptoms (LUTS) due to prostatitis and acquired PE were excluded from the study. A local anesthetic was applied to the skin of glans penis for 30 minutes before the injection of 2 ml HA in glans penis via 30-gauge needle using our new Five-puncture technique. Intra-vaginal ejaculatory latency time (IELT) was measured at 1, 3, 6 and 12 months after injection. Results Thirty patients completed our study follow up schedule. Mean age of the patients was 41.72 ± 8.50, while mean age of female partner was 37.23 ± 8.54 years. IELT was highly significantly increased (P-value < 0.001) after HA gel injection from baseline, which was in maximum 37.83 ± 11.01 sec at baseline to 323.03 ± 42.06, 281.07 ± 41.05, 241.03 ± 43.09 and 235.6 ± 41.87 sec after 1, 3, 6 and 12 months, respectively, after injection. Three patients complained from discomfort at the site of injection, two from bullae formation at the site of injection and one from ecchymosis, and all resolved spontaneously after 1 week to 10 days after injection. Conclusion HA gel injection in glans penis using our new five-puncture technique is a safe and effective method that ensures a modest long-term significant increase in IELT and improves ejaculatory control.

Abstract
Abstract
Background
Premature ejaculation (PE) is a common male sexual dysfunction worldwide. It leads to substantial distress in men and their partners, constitutes a serious threat to the quality and stability of romantic relationships, and results in a decreased quality of life in a large part of the population.
Aim
We investigated the prevalence of PE and correlated factors in an urban sample of Chinese men.
Methods
In total, 1976 Chinese men aged 18 to 50 years responded to an online questionnaire regarding background information, present and previous sexual experience, frequency of different types of sex, as well as erectile and ejaculatory function.
Outcomes
Participants’ age, assigned sex at birth, sexual identity, relationship status, present and previous sexual experience, frequency of sexual activities, International Index of Erectile Function–5, and Checklist for Early Ejaculation Symptoms were used in the analyses.
Results
Forty-four (2.3%) participants had scores that were indicative or strongly indicative of PE, which was highly correlated with erectile problems. Men with more sexual experience (ie, more sexual partners and longer duration of being sexually active) had fewer ejaculatory problems. More frequent masturbation was associated with ejaculatory problems when controlling for age and education. More frequent partnered sex (ie, penile-vaginal sex) was associated with fewer ejaculatory problems. Ejaculation latency times for different types of sexual activities were positively correlated.
Clinical Translation
The results indicated that ejaculatory problems have complex relationships with sexual experience that clinicians should be aware of.
Strengths and Limitations
This study was the first to investigate PE with the Checklist for Early Ejaculation Symptoms as the measurement tool and the associations between PE and sexual experience, frequency of sexual activities, and sexual function in a large Chinese sample. However, self-reported ejaculation latency times may suffer from problems with validity.
Conclusion
Men’s sexual experience (ie, more sexual partners and longer duration of being sexually active) has an effect on their sexual function, which in turn affects their sexual activity.

Abstract
BACKGROUND Premature ejaculation (PE) is still a tough problem in drug treatment. Many clinical trials have proven that traditional Chinese medicine (TCM) has a significant effect in the treatment of PE. This article aims to provide the latest evidence for the efficacy and safety of TCM combined with selective serotonin reuptake inhibitors (SSRIs) in the treatment of PE. METHODS We looked for randomized controlled trials (RCTs) from China National Knowledge Infrastructure, Wanfang, VIP Database, MEDLINE, PubMed, Web of Science, EMBASE, and Cochrane Library until June 30, 2022. STATA 15.1 software was used to analyze all data for this article. The quality of the included articles was evaluated using the Cochrane Reviewer's Handbook 5.3. RESULTS Finally, we selected 16 high-quality RCTs in our meta-analysis, which containing 889 patients. Meta-analysis suggested that, compared with SSRIs alone, combination of TCM with SSRIs increased significantly intravaginal ejaculation latencv time and the scores of ejaculation control ability, sexual life satisfaction, PE-related distress, and communication difficulties between partners related to PE. Also, there was no significant difference in adverse effects between the two groups. In addition, the results of publication bias test showed that no significant bias occurred. CONCLUSION The combined use of TCM and SSRIs has significant effect in the treatment of PE compared with SSRIs monotherapy and was generally well tolerated. Due to the small sample size, multicenter and large sample RCT is still needed in the future to further confirm the effectiveness and safety of TCM combined with SSRIs in the treatment of PE.

Chen J, Wang Q, Huang X, Xu Y, Xiang Z, Liu S, Yang J, Chen Y. Potential biomarkers for distinguishing primary from acquired premature ejaculation: A diffusion tensor imaging based network study. Front Neurosci 2022; 16:929567. [PMID: 36340794 PMCID: PMC9626512 DOI: 10.3389/fnins.2022.929567] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Accepted: 10/03/2022] [Indexed: 11/24/2022] Open
Abstract
Introduction Premature ejaculation (PE) is classified as primary and acquired and may be facilitated by different pathophysiology. Brain plays an important role in PE, however, differences in the central neuropathological mechanisms among subtypes of PE are unknown. Materials and methods We acquired diffusion tensor imaging (DTI) data from 44 healthy controls (HC) and 47 PE patients (24 primary PE and 23 acquired PE). Then, the whole-brain white matter (WM) structural networks were constructed and between-group differences of nodal segregative parameters were identified by the method of graph theoretical analysis. Moreover, receiver operating characteristic (ROC) curves were performed to determine the suitability of the altered parameters as potential neuroimaging biomarkers for distinguishing primary PE from acquired PE. Results PE patients showed significantly increased clustering coefficient C(i) in the left inferior frontal gyrus (triangular part) (IFGtriang.L) and increased local efficiency Eloc(i) in the left precental gyrus (PreCG.L) and IFGtriang.L when compared with HC. Compared to HC, primary PE patients had increased C(i) and Eloc(i) in IFGtriang.L and the left amygdala (AMYG.L) while acquired PE patients had increased C(i) and Eloc(i) in IFGtriang.L, and decreased C(i) and Eloc(i) in AMYG.L. Compared to acquired PE, primary PE patients had increased C(i) and Eloc(i) in AMYG.L. Moreover, ROC analysis revealed that PreCG.L, IFGtriang.L and AMYG.L might be helpful for distinguishing different subtypes of PE from HC (PE from HC: sensitivity, 61.70–78.72%; specificity, 56.82–77.27%; primary PE from HC: sensitivity, 66.67–87.50%; specificity, 52.27–77.27%; acquired PE from HC: sensitivity, 34.78–86.96%; specificity, 54.55–100%) while AMYG.L might be helpful for distinguishing primary PE from acquired PE (sensitivity, 83.33–91.70%; specificity, 69.57–73.90%). Conclusion These findings improved our understanding of the pathophysiological processes that occurred in patients with ejaculatory dysfunction and suggested that the abnormal segregation of left amygdala might serve as a useful marker to help clinicians distinguish patients with primary PE from those with acquired PE.

Abstract
The link between sexual dysfunction and male infertility has been well established. In addition to male infertility, male patients with couple pregnancy loss and preconception care are the most frequent reasons for the treatment of andrology outpatients. However, there is a paucity of information simultaneously investigating male sexual dysfunction in these males with different reproduction situations. A cross-sectional study was performed in consecutive series of 1256 participants, including 509 men with infertility, 437 couples with pregnancy loss, and 310 men for preconception care. All men completed a questionnaire on baseline demographic information, sexual behavior characteristics and validated research tools, including Premature Ejaculation Diagnostic Tool, seven-item Generalized Anxiety Disorder Scale, and International Index of Erectile Function. The prevalence of erectile dysfunction and premature ejaculation was 30.6%, 20.8% in the infertility population and 27.0%, 18.5% in pregnancy loss individuals, was much lower in preconception care men, at 9.3%, 11.9% (p < 0.05), respectively. Infertility and pregnancy loss couples were more biased toward choosing timed intercourse than preconception care couples, with rates of 19.6% in Infertility group and 17.4% in pregnancy loss groups, versus 10.0% (p < 0.05) in preconception care couples. The infertile and pregnancy loss men also reported higher rate of anxiety state than the preconception care group. The prevalence of erectile dysfunction increased gradually with the duration of infertility and the frequency of pregnancy loss, with a highest odds ratio of 7.346 (95% CI:4.329-12.467; P < 0.001) among men with ≥5 years of infertility, 6.282 (95% CI:3.446-11.453; P < 0.001) among couples ≥3 pregnancy loss when compared with preconception care group. The prevalence of erectile dysfunction, premature ejaculation and timed intercourse were comparable in pregnancy loss and infertile males, were all noticeably higher than preconception care group. There was also a trend toward a higher incidence of erectile dysfunction with longer duration of infertility or the more frequent of pregnancy loss.

Abstract
BACKGROUND Premature ejaculation (PE) is the most common sexual dysfunction in males. A previous qualitative study identified six communication strategies described by GPs to tackle this topic during consultations. AIM To determine whether these six strategies are more effective than usual care for promoting discussion about PE between patients and their GPs. DESIGN AND SETTING Cluster randomised controlled trial, stratified in four French regions, with an intervention group (GPs who received a training session on the six communication strategies) and a control group (routine medical care). Participants were males aged 18-80 years consulting for a sexual, urogenital, or psychological reason. METHOD The efficacy of the training session in communication skills, compared with usual care, was evaluated by determining the percentage of patients who discussed PE with their GP (primary outcome). The percentage of enrolled patients with PE was calculated using a cut-off score >9 of the premature ejaculation diagnostic tool (PEDT) completed by the enrolled patients at Week 4 after the consultation. The quality-of-life changes were evaluated as the SF-12 scale score difference between baseline and Week 4 post-consultation. RESULTS In total, 130 patients were included by 32 GPs (n = 16 in the intervention and n = 16 in the control group). The percentage of patients who discussed PE was higher in the intervention group than in the control group (42.0% versus 4.9%, absolute difference = 37.1%; 95% confidence intervals [CI] = 24% to 50%, P<0.001). CONCLUSION Training GPs in communication strategies about PE improves its detection.

Correlations between Personality Traits, Patient-Reported Outcome, and Chronic Prostatitis Symptoms in Men with Different Premature Ejaculation Syndromes. BIOMED RESEARCH INTERNATIONAL 2022; 2022:8049976. [PMID: 35434135 PMCID: PMC9012653 DOI: 10.1155/2022/8049976] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Revised: 03/07/2022] [Accepted: 03/21/2022] [Indexed: 11/17/2022]
Abstract
Although the personality traits (PT), patient-reported outcome (PRO), and chronic prostatitis (CP) symptoms in premature ejaculation (PE) have been evaluated, there was no study to assess their correlations in men with different PE syndromes. The purpose of this study was to assess the correlations between the PT, PRO, and CP symptoms in men with different PE syndromes. Between January 2019 and January 2021, a cross-sectional field study was conducted in our andrology clinic. Men with the complaints of PE were divided into lifelong PE (LPE), acquired PE (APE), variable PE (VPE), and subjective PE (SPE). All subjects were required to complete a verbal questionnaire with the PRO, National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), and Temperament and Character Inventory (TCI-R). Finally, 479 men with the complaints of PE and 365 without the complaints of PE were enrolled. The incidence of PE syndromes in PE complaint group was as follows: LPE 16.70%, APE 48.85%, VPE 11.27%, and SPE 23.17%. Mean ages in PE complaint group were 42.53 ± 12.25 years. In the PE complaint group, the novelty seeking (NS) scores were strongest correlated with the personal distress and quality of life (QOL). The harm avoidance (HA) scores were strongest correlated with the severity of PE and pain syndromes. The self-transcendence (ST) scores were strongest correlated with the satisfaction with sexual intercourse and QOL. In addition, strongest association between the total scores of NIH-CPSI and the NS or ST scores was also found in the APE group. The HA scores were also strongest correlated with the total scores of NIH-CPSI in SPE. Strongest association between the total scores of NIH-CPSI and the NS/TI or ST/CI scores was also found in the APE group. The HA/TI scores were also strongest correlated with the total scores of NIH-CPSI in SPE.

Abstract
Objective To investigate the clinical efficacy and possible mechanism of electroacupuncture in the treatment of premature ejaculation. Methods 50 cases of premature ejaculation patients who met the diagnostic criteria were randomly divided into 2 groups with 25 cases in each group. The observation group was treated with electroacupuncture, and the control group was treated with Longdan Xiegan decoction. The treatment period was 4 weeks. Ejaculation latency (IELT), sexual satisfaction score of patients, sexual satisfaction score of partners, testosterone test, and drug safety assessment were performed in all 4 groups before and after treatment. Results IELT was prolonged in all groups after treatment, the difference was statistically significant (P < 0.05). At the same time, the IELT of the observation group was significantly higher than that of the control group after treatment. Life satisfaction scores of patients and spouses in 2 groups were improved after treatment compared with before treatment, the difference was statistically significant (P < 0.05). After treatment, the satisfaction scores of patients and spouses in the observation group were higher than those in the control group, and the difference was statistically significant (P < 0.05). Before treatment, there was no significant difference in serum testosterone levels among all groups (P > 0.05). Serum testosterone levels in all groups were decreased after treatment compared with before treatment, with statistical significance (P < 0.05). After treatment, the serum testosterone level of the observation group was lower than that of the control group, and the difference was statistically significant (P < 0.05). During the treatment, the adverse reactions in each group disappeared after treatment, and no obvious abnormality was observed in the safety indicators. Conclusion Electroacupuncture can improve the symptoms of premature ejaculation, which may be related to the regulation of serum testosterone by acupuncture.

Abstract
Background Sexual dysfunction, namely, erectile dysfunction (ED) and premature ejaculation (PE), has been found to be associated with abnormal structural connectivity in the brain. Previous studies have mainly focused on a single disorder, however, convergent and divergent structural connectivity patterns of the brain network between ED and PE remain poorly understood. Methods T1-weighted structural data and diffusion tensor imaging data of 28 patients with psychological ED, 28 patients with lifelong PE (LPE), and 28 healthy controls (HCs) were obtained to map the white matter (WM) brain networks. Then, the graph-theoretical method was applied to investigate the differences of network properties (small-world measures) of the WM network between patients with ED and LPE. Furthermore, nodal segregative and integrative parameters (nodal clustering coefficient and characteristic path length) were also explored between these patients. Results Small-world architecture of the brain networks were identified for both psychological ED and LPE groups. However, patients with ED exhibited increased average characteristic path length of the brain network when compared with patients with LPE and HCs. No significant difference was found in the average characteristic path length between patients with LPE and HCs. Moreover, increased nodal characteristic path length was found in the right middle frontal gyrus (orbital part) of patients with ED and LPE when compared with HCs. In addition, patients with ED had increased nodal characteristic path length in the right middle frontal gyrus (orbital part) when compared with patients with LPE. Conclusion Together, our results demonstrated that decreased integration of the right middle frontal gyrus (orbital part) might be a convergent neuropathological basis for both psychological ED and LPE. In addition, patients with ED also exhibited decreased integration in the whole WM brain network, which was not found in patients with LPE. Therefore, altered integration of the whole brain network might be the divergent structural connectivity patterns for psychological ED and LPE.

Abstract
Psychiatric drugs have primacy for off-label prescribing. Among those, selective serotonin reuptake inhibitors (SSRIs) are highly versatile and, therefore, widely prescribed. Moreover, they are commonly considered as having a better safety profile compared to other antidepressants. Thus, when it comes to off-label prescribing, SSRIs rank among the top positions. In this review, we present the state of the art of off-label applications of selective serotonin reuptake inhibitors, ranging from migraine prophylaxis to SARS-CoV-2 antiviral properties. Research on SSRIs provided significant evidence in the treatment of premature ejaculation, both with the on-label dapoxetine 30 mg and the off-label paroxetine 20 mg. However, other than a serotoninergic syndrome, serious conditions like increased bleeding rates, hyponatremia, hepatoxicity, and post-SSRIs sexual dysfunctions, are consistently more prominent when using such compounds. These insidious side effects might be frequently underestimated during common clinical practice, especially by nonpsychiatrists. Thus, some points must be addressed when using SSRIs. Among these, a psychiatric evaluation before every administration that falls outside the regulatory agencies-approved guidelines has to be considered mandatory. For these reasons, we aim with the present article to identify the risks of inappropriate uses and to advocate the need to actively boost research encouraging future clinical trials on this topic.

Abstract
Premature ejaculation (PE) is the most common male sexual dysfunction, with 30% of men experiencing PE worldwide. According to the generally accepted classification, there are two types of PE: lifetime PE and acquired PE. Various biological and psychological causes are known to be involved in the etiology of PE. However, due to the incomplete definition and etiopathogenesis of PE, there is no effective treatment. Although clinical and animal studies indicate that hormones play a role in controlling the ejaculation process, the precise endocrine mechanisms are unclear. In addition, little is known about the role of endocrine disorders in PE etiology. However, there is evidence that diabetes mellitus (DM), obesity, metabolic syndrome (MetS), thyroid gland disorders, pituitary gland disorders, and vitamin D deficiency affect the prevalence of PE. Moreover, it has been reported that the prevalence of PE decreases with treatment of these endocrine disorders. In this review, the relationship between PE and DM, MetS, obesity, vitamin D deficiency, and thyroid and pituitary gland disorders is summarized.

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.

Functional Connectivity of Nucleus Accumbens Is Associated with Lifelong Premature Ejaculation in Male Adults : A Resting-state fMRI Study. Clin Neuroradiol 2021; 32:655-663. [PMID: 34714363 DOI: 10.1007/s00062-021-01105-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2021] [Accepted: 09/17/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE Ejaculation represents a crucial component of sexual behavior in men, which is involved in reward functions of certain brain areas including the nucleus accumbens (NAcc). Lifelong premature ejaculation (PE) is one of the most prevalent sexual dysfunctions in men. It is suggested to be related to abnormal brain function. This study aimed to explore changes of the functional connectivity patterns of NAcc and possible correlations of the neuroimaging abnormalities with clinical features in lifelong PE patients. METHODS The sample consisted with 42 lifelong PE patients and 30 healthy controls. All participants underwent functional magnetic resonance imaging scans and clinical symptoms. The functional connectivity (FC) approach was applied to investigate differences of NAcc-seed intrinsic connectivity between two groups and correlation analysis was used to access possible relationships between the imaging findings and clinical features, such as premature ejaculation diagnostic tool (PEDT) or intravaginal ejaculatory latency time (IELT). RESULTS Results showed that lifelong PE patients had decreased FC between the NAcc and thalamus, superior temporal pole, superior temporal cortex (STC), inferior frontal gyrus (IFG), orbitofrontal cortex, caudate and putamen. A significantly negative correlation between the PEDT score and NAcc-STC connectivity (r = -0.46) was found in lifelong PE patients, while IELT score positively correlated with the NAcc-IFG connectivity (r = 0.48) and NAcc-thalamus connectivity (r = 0.46). CONCLUSION The findings may facilitate a more sophisticated understanding of neural mechanisms of lifelong PE, particularly associated with the NAcc-related intrinsic connectivity during the resting state.

Abstract
OBJECTIVES To detect seed-based functional connectivity (FC) between various cortical sub-regions and the thalamus in lifelong premature ejaculation (LPE) patients and explore whether specific thalamocortical networks are significantly altered in PE patients compared to healthy controls (HCs) METHODS: Fifty non-medicated LPE patients and 40 age-matched HCs underwent a resting-state functional MRI. FC was adopted to identify specific thalamocortical connectivity between the thalamus and 6 cortical regions of interest (i.e., the motor cortex/supplementary motor, the prefrontal cortex, the temporal lobe, the posterior parietal cortex, the somatosensory cortex and the occipital lobe). In LPE patients, regression analysis was subsequently conducted to assess relationships of thalamocortical connectivity with the Premature Ejaculation Diagnostic Tool (PEDT) score and the Intravaginal Ejaculatory Latency Time (IELT). RESULTS LPE patients had significantly decreased FC between the motor cortex and bilateral ventral thalamus, between the prefrontal cortex and left dorsomedial thalamus, as well as between the temporal cortex and bilateral ventromedial thalamus. In LPE patients, PEDT score was significantly positively associated with the thalamus-posterior parietal cortex FC, and negatively associated with the thalamus-temporal cortex FC, while IELT was positively associated with the thalamus-temporal cortex and thalamus-motor cortex FC. CONCLUSION These results enrich the imaging evidence for the understanding of the neurobiological mechanisms and/or consequences of LPE.

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
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
Lifelong premature ejaculation (PE) is one of the most prevalent male sexual dysfunctions. It is still not well known about the possible neural mechanisms of lifelong PE. This study tried to investigate the abnormal characteristics of brain functional networks of lifelong PE and to assess relationships of PE-related functional abnormalities with clinical symptoms. Functional magnetic resonance imaging (fMRI) data and clinical symptoms were collected from 45 lifelong PE patients and 37 healthy controls (HCs) since 2016, including disease and sexual life history, intravaginal ejaculatory latency time measured by stopwatch and other scales. The degree centrality (DC) approach were applied to distinguish altered brain functions between the two groups (p < 0.05, false discovery rate corrected). Correlation analysis was then performed to examine relationships between the imaging findings and clinical symptoms (p < 0.05, Bonferroni corrected). Results showed that compared with HCs, lifelong PE patients had increased DC value in the medial prefrontal cortex (mPFC), precuneus and primary somatosensory cortex (SI) as well as decreased DC value in the insula and orbitofrontal cortex. After controlling for anxiety and depression levels, the significant difference in the mPFC was not found. The DC value in the SI positively correlated with premature ejaculation diagnostic tool (PEDT) score in the patients. The present findings indicate that lifelong PE patients have altered DC in brain regions involved in sensation, motivation and inhibitory control processing. Our study may improve our understanding and provide a new sight into the further research of lifelong PE.

Abstract
Background Lifelong premature ejaculation (PE) is one common male sexual dysfunction and is implicated in widespread structural and functional abnormalities of bilateral hemispheres. However, whether the inter-hemisphere functional connectivity (FC) of lifelong PE patients was altered still remain unclear. Methods Thirty-four lifelong PE patients and 30 healthy controls (HCs) were enrolled in this study and all underwent T1-weighted and resting-state functional MRI (fMRI) scan. The voxel-mirrored homotopic connectivity (VMHC) measure and independent sample t-test were applied to examine the alterations of VMHC values in the patients relative to HCs with the significant threshold at P<0.05, false discovery rates corrected. Correlation analysis was adopted to calculate the relationships between the imaging results and clinical characteristics of patients (P<0.05, Bonferroni corrected). Receiver operating characteristic (ROC) curve analysis was performed to investigate the possible biomarkers for distinguishing the patients from the HCs using the VMHC values of inter-group differences. Results The results revealed that compared with HCs, lifelong PE patients had higher VMHC values in the precentral gyrus (PG), primary somatosensory cortex (S1), supplementary motor area (SMA), precuneus, middle temporal cortex (MTC), superior temporal pole (STP), thalamus, caudate and middle cingulate cortex (MCC). Correlation analysis showed that the mean VMHC values in the S1 negatively correlated with intravaginal ejaculation latency time (IELT) in the patient group. Furthermore, the caudate revealed the well classification power from the ROC analysis. Conclusions The present study showed the abnormal inter-hemisphere interaction and integration of information involved in ejaculation inhibitory control, sensorimotor mediation and self-reference processing including the thalamus, caudate, MCC, widespread parietal cortex and temporal cortex in lifelong PE patients compared with HCs. Correlation analysis and ROC analysis revealed the importance of S1 and caudate in lifelong PE. Notably, the ROC result of caudate might show the core roles of caudate played in the pathophysiology of lifelong PE.

Abstract
Little is known about how the aberrant structural and functional connectivity relates to the rapid ejaculation. Data of diffusion tensor imaging and resting state functional magnetic resonance imaging were acquired from 32 PE patients and 38 healthy controls (HCs). Firstly, we investigated the structural connectivity (SC) disruptions of PE patients using the method of graph theoretical analysis. Brain regions with impaired nodal strength were then defined as regions of interest (ROI). Secondly, the corresponding functional connectivity (FC) changes were explored. Finally, the correlation analyses were performed between brain areas with abnormal connectivity and clinical characteristics. Structural analysis revealed that PE patients had increased nodal strength in the right superior frontal gyrus (dorsolateral), left middle frontal gyrus, right superior frontal gyrus (medial), right superior frontal gyrus (medial orbital) and decreased nodal strength in the left amygdala. FC analysis revealed that PE patients had decreased FC values in the default mode network, visual recognition network and subcortical network, as well as increased FC values in the attention network. Moreover, correlation analysis revealed that the nodal strength of right superior frontal gyrus (dorsolateral) was negatively associated with the intra-vaginal ejaculation latency, while FC values between the left middle frontal gyrus and middle occipital gyrus were positively related to the total scores of the premature ejaculation diagnostic tool (PEDT). Our results indicated that PE might be associated with the abnormal SC of areas in the prefrontal-amygdala pathway and aberrant FC in certain functional brain networks, especially in default mode network.

Abstract
OBJECTIVES To analyze the abnormal amygdala structure and function in lifelong premature ejaculation (PE) patients compared with healthy controls (HCs). METHODS Forty-four lifelong PE patients and thirty-one HCs were enrolled in this study. Each subject was diagnosed with PE using a Premature Ejaculation Diagnostic Tool (PEDT) and intravaginal ejaculation latency time (IELT) score. Based on t-tests and Pearson correlation analysis, the voxel-based morphometry and functional connectivity (FC) analyses were applied to evaluate brain structural and functional changes by using T1-weighted and resting-state functional magnetic resonance imaging scans. RESULTS Lifelong PE patients had decreased gray matter volume in the bilateral amygdala and increased FC between the amygdala and precuneus, posterior cingulate cortex (PCC), and middle temporal cortex (MTC), as well as decreased FC between the amygdala and precentral gyrus, insula, and inferior frontal gyrus. Moreover, significantly negative correlations between the IELT score and the mean z-score from amygdala-MTC (r = -0.49) and amygdala-PCC (r = -0.48) FC were found in lifelong PE patients. CONCLUSIONS Our study investigated the abnormal amygdala-related structure and connectivity patterns in PE patients, which might provide novel perspective for understanding the crucial role of the amygdala in the neural mechanism of PE. KEY POINTS • As one of the most common diseases in men, PE may be related to abnormal brain mechanisms. • Functional and structural magnetic resonance imaging used to explore amygdala abnormalities in PE patients. • The correlation between clinical scores and functional connectivity was used to assess the reasonability of the results.

Abstract
Premature ejaculation (PE) and poor ejaculatory control are multidimensional sexual symptoms estimated to affect almost one-third of men, severely impairing the overall quality of life of patients and their partners. However, patients who do not completely fulfil the definition criteria for PE rarely receive a diagnosis or adequate treatment, with the risk of subsequent progression from initial, subclinical symptoms to clinically overt PE, frequently with other sexual comorbidities. Thus, the current definitions of PE warrant review, in order to consider and propose a new taxonomy encompassing other unaddressed, crucial clinical aspects of PE. These newly proposed criteria include the recommendation for a primary screening for erectile dysfunction (ED), as PE and ED can be comorbid in up to 50% of patients but have never before been considered as a unified clinical entity. In order to facilitate clinical practice and improve clinical management of men with PE and comorbid conditions, we propose and define the new taxonomic clinical entities of subclinical PE (SPE) and loss of control of erection and ejaculation (LCEE). Application of these diagnoses to men who meet the criteria for SPE and/or LCEE, but not the overt conditions, could improve access to treatment for these patients and reduce progression to the more serious clinical disorder.

J Sex Med 2020; 18:72-82. [PMID: 33339761 DOI: 10.1016/j.jsxm.2020.11.001] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2020] [Revised: 11/09/2020] [Accepted: 11/10/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND Although temperament-character traits and attitudes toward premature ejaculation (PE) are known to be associated with PE, it is of great significance to study them in PE. Moreover, few studies have evaluated these traits and attitudes in the new classification of 4 subtypes of PE. AIM We investigated the temperament-character traits and attitudes toward PE in 4 types of PE and their associations with PE. METHODS Between December 2018 and December 2019, we conducted a survey in our hospital, and enrolled 350 men who complained of PE and 252 men without any complaint of PE. Temperament-character traits and attitudes toward PE were independently assessed by the Temperament and Character Inventory-Revised and several targeted questions, respectively. The Index of Premature Ejaculation (IPE) was used to evaluate ejaculation control, sexual life satisfaction, and distress caused by PE. OUTCOMES The outcomes included differences of temperament-character traits and attitudes toward PE among 2 groups and their associations with PE. RESULTS Of the 2 groups, men with PE complaints had lower novelty seeking/self-transcendence (NS/ST) scores and higher harm avoidance (HA) scores vs men without any complaints of PE. Among the 4 types of PE, men with variable PE had the highest score of HA and lowest score of NS; the lowest score of ST was recorded in men with lifelong PE. Additionally, the total and subdomain scores of IPE in men with subjective PE were higher than the other subtypes of PE. After adjusting for age, positive correlations were observed in HA score and total and subdomain scores of IPE, whereas the inverse was true corresponding to NS and ST. CLINICAL IMPLICATIONS The current study has provided a new perspective for understanding the impact of psychological factors on PE. STRENGTHS & LIMITATIONS This is the first study to systematically assess the effects of personality traits and attitudes on PE, especially among the 4 types of PE. The main drawback is that the generalizability of this study may be limited by the fact that it was conducted in a single cultural/societal background. CONCLUSION Men who complained of PE tended to react with indifference or rejection to novelty, tended to feel unsatisfied, cannot effectively adapt to changes in the surrounding environment, and tended to avoid situations involving risk. These characteristics could lead to their becoming disheartened when faced with PE. Furthermore, the attitude of men with PE reflects the needs of the patient during treatment from one aspect.

Pharmaceutics 2020; 12:pharmaceutics12121187. [PMID: 33297307 PMCID: PMC7762256 DOI: 10.3390/pharmaceutics12121187] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 11/24/2020] [Accepted: 12/02/2020] [Indexed: 01/23/2023] Open
Abstract
The study aimed at developing a liquisolid tablet (LST) containing tadalafil (TDL) and dapoxetine (DPX) with improved bioavailability as a potential therapy for male sexual dysfunction. A mixture of nonvolatile solvents, namely PEG 200 and Labrasol®, was utilized to prepare LSTs that were assessed for their quality characteristics. The Box–Behnken design (BBD) was employed to statistically explore the effect of the formulation factors on the quality attributes of LSTs. Furthermore, an in vivo pharmacokinetic study was carried out for the optimized LST in comparison with the marketed tablets on healthy human volunteers. The optimized LST revealed acceptable quality limits with enhanced dissolution for both APIs. The pharmacokinetic parameters after oral administration of the optimized LST indicated that the Cmax of TDL in LSTs was 122.61 ng/mL within 2h compared to the marketed tablets, which reached 91.72 ng/mL after 3 h, indicating the faster onset of action. The AUC was improved for TDL in LST (4484.953 vs. 2994.611 ng/mL∙h in the marketed tablet) and DPX in LST (919.633 vs. 794.699 ng/mL∙h in the marketed tablet). This enhancement in bioavailability potentially minimizes the associated side effects and improves the treatment of male sexual dysfunction, particularly for diabetic patients.

Aberrant default mode network and auditory network underlying the sympathetic skin response of the penis (PSSR) of patients with premature ejaculation: A resting-state fMRI study. Andrology 2020; 9:277-287. [PMID: 32996293 DOI: 10.1111/andr.12914] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2020] [Revised: 09/21/2020] [Accepted: 09/23/2020] [Indexed: 12/27/2022]
Abstract
INTRODUCTION Hyperactivity of the sympathetic nervous system is considered as an important component involved in the pathological mechanisms of premature ejaculation (PE). However, the neural mechanisms of PE with high sympathetic activity are still not well understood. METHODS The activity of the sympathetic innervations in the penis was evaluated by the sympathetic skin response of the penis (PSSR) with an electromyograph and evoked potential equipment. Resting-state functional magnetic resonance imaging (fMRI) data were acquired from 18 PE patients with high sympathetic activity (sPE), 17 PE patients with normal sympathetic activity (nsPE), and 24 healthy controls (HC). We investigated the neural basis of sPE based on the measure of regional homogeneity (ReHo). Moreover, the correlations between brain regions with altered ReHo and PEDT scores and PSSR latencies in the patient group were explored. RESULTS Altered ReHo values among three groups were found in the temporal, cingulated, and parietal cortex in the default mode network (DMN), as well as the temporal cortex in the auditory network (AUD). Compared with HC, Patients with sPE had increased ReHo values of brain regions in DMN, AUD, and decreased ReHo values of brain regions in DMN. In addition, increased ReHo values were found in DMN of patients with nsPE, while decreased ReHo values were found in DMN and the attention network (AN). Moreover, sPE patients had increased ReHo values in AUD and decreased ReHo values in DMN when compared with nsPE patients. Finally, altered ReHo values of brain regions in DMN and AUD were associated with PEDT scores and PSSR latencies in the patient group. CONCLUSION Our results suggested that PE patients had abnormal ReHo values in DMN, AUD, and AN. Patients with sPE were characterized by increased neuronal activity in AUD and decreased activity in DMN. This highlighted the significances of DMN, AUD, and AN in the pathophysiology of PE and also provided potential neuroimaging biomarkers for distinguishing sPE from nsPE and HC.

Abstract
This study aimed to investigate the Premature Ejaculation Profile (PEP) and its related factors in couples using contraceptive withdrawal (WD). The study sample was composed of 108 participants including 54 males and 54 females (their partners) who used WD. The data were collected via a questionnaire and the male and female forms of the PEP. The mean total PEP index score of the couples (female (F); 1.69 ± 0.55 and male (M); 1.65 ± 0.36) was below the average possible score. Although both males and their partners generally rated control over ejaculation (F; 57.4%, M; 61.1%) and satisfaction with sexual intercourse (F; 63%, M; 79.7%) as good/very good, they rate personal distress related to ejaculation (F; 64.8%, M; 83.4%) and interpersonal difficulty related to ejaculation (F; 81.5%, M; 92.6%) as 'extremely/quite a lot'. As the time of using WD increased, male control over ejaculation increased (p = .019); as the marriage duration (p = .045) and ages (F; p = .012, M; p = .045) of the couples increased, their problems related to ejaculation increased. According to the results, couples who use WD experience PE-related problems, and the problems they experience vary depending on the period of WD use, marriage duration and age.

Abstract
The primary premature ejaculation (PPE) is a common male sexual disorder. We proposed a novel behavioral therapy for PPE through regular penis-root masturbation (PRM). Nine heterosexual men with PPE completed the self-controlled study. After a 3-month PRM training, the median intravaginal ejaculatory latency time (IELT) increased from 60 s to 180 s (P = 0.018), and the mean Premature Ejaculation Diagnostic Tool (PEDT) score decreased from 14.8 ± 3.7 to 12.8 ± 4.1 (P = 0.074). Five out of eight patients had the prolonged dorsal nerve somatosensory evoked potential (DNSEP). The results suggest that PRM has a short-term therapeutic effect. Randomized controlled trials are needed to validate the efficacy.

Abstract
We conducted the study to investigate the association between metabolic syndrome (MetS) and acquired premature ejaculation (APE). From January 2017 to December 2019, 1,000 subjects, 500 men with APE (APE group) and 500 men without APE (control group), were selected. Self-estimated intravaginal ejaculatory latency time (IELT) and Premature Ejaculation Diagnostic Tool (PEDT) were recorded from each participant to evaluate APE. Detailed physical examinations, body composition analysis and blood tests were all assessed. The neck circumference, waist circumference, visceral fat rating, fat mass, fasting blood glucose (FBG) and highly sensitive C-reactive protein (hs-CRP) in the APE group were significantly higher than the control group (p < .05 for all). Furthermore, the APE population had a higher prevalence of MetS than the control group (49.4% versus 35.6%, p = .000). Consistent results could also be observed in terms of the number of MetS components and each component of the MetS (both p < .05). Moreover, both the prevalence of APE and the severity of PE increased significantly as the number of MetS components increased. Finally, in the multivariate analysis, we found that both MetS and hs-CRP were independent risk factors for APE (both p < .01). The results indicated that APE was related to MetS but not its components.

Abstract
Premature ejaculation (PE) is the most common male sexual dysfunction, which represents a diagnostic as well as a therapeutic challenge for physicians. However, no universally accepted definition is currently available for PE. As a result, physicians continue to diagnose patients with PE according to major guidelines set by the professional societies. These guidelines either recommend the use of validated questionnaires or patient-reported outcomes. Recent efforts directed toward classifying PE may help provide a better understanding of the prevalence and risk factors of this disorder. While the exact etiology of PE has not been clearly elucidated, several risk factors have been strongly reported in the literature. Clearly, to understand the revised definition of PE, its etiology and pathophysiology is necessary to improve the clinical management of this medical condition and form the basis of future research in this regard. In this review, we highlight the past and current definitions of PE and present an appraisal on the classifications and theories suggested for the etiopathogenesis of PE.

Abstract
We investigated changes in patterns of reported male SDs at a single academic centre over a 10-year time frame. Comprehensive data of 2013 patients consecutively assessed for the first time by a single Sexual Medicine expert between 2006 and 2019 has been analysed. All patients were assessed with a thorough sexual and medical history. Primary reason for seeking medical help at first assessment was recorded for all patients and categorized as: erectile dysfunction (ED), premature ejaculation (PE), low/reduced sexual desire/interest (LSD/I), Peyronie's disease (PD), and other SDs. Linear and logistic regression models tested the association between different reasons for seeking medical help and the time at first evaluation. Local polynomial regression model explored the probability of reporting different SDs over the analysed time frame. Median (IQR) age at first clinical assessment was 50 (38-61) years. Overall, most patients were assessed for ED (824; 41%), followed by PD (369; 18%), PE (322; 16%), LSD/I (204; 10%) and other SDs (294; 15%). Significant changes in terms of reported SD over the analysed time frame were observed. The likelihood of assessing patients for ED significantly increased up to 2013, with a decrease in the past 5 years (p < 0.001). PE assessment at presentation linearly decreased over time (OR: 0.94; 95% CI: 0.91-0.96; p < 0.001). Patients assessed during the past few years were more likely to report PD (OR: 1.20; 95% CI: 1.15-1.25; p < 0.001) and LSD/I (OR: 1.21; 95% CI: 1.16-1.26; p < 0.001), with a linear increase over the evaluated time frame. Likewise, patients were also more likely to report other SDs (Coeff: 1.06; 95% CI: 1.02-1.10; p = 0.004), with a linear increase over time. These results may reflect real changes in SD incidence, increased public awareness towards different SDs and the possible impact of novel treatments available on the market throughout the same time frame.

Abstract
Background: Premature ejaculation has a complex etiology, and its pathophysiology is still unclear, with penile hypersensitivity being the most accepted hypothesis. The aim was to investigate the efficacy and safety of a computed tomography-guided pudendal nerve block at the level of the sacrospinous ligament and the Alcock's canal in patients with premature ejaculation refractory to conventional pharmacological treatment.Methods: This is a prospective pilot study involving five patients suffering from premature ejaculation refractory to standard treatment and clinical features of pudendal nerve entrapment. A CT-guided infiltration of ropivacaine and methylprednisone was done at the levels of sacrospinous ligament and Alcock's canal. Intra-vaginal ejaculatory latency time (IELT) was recorded several times for each patient before and after infiltration. International Index of Erectile Function (IIEF-5), Premature Ejaculation Diagnostic Tool (PEDT) and Sexual Quality of Life-Male version (SQoL-M) questionnaire were also evaluated before and after infiltration.Results: Overall IELT differed significantly before and after treatment (21.94 vs 215.42 s; p = 0.039). IIEF-5, PEDT and SQoL-M also differed significantly before and after treatment. No complications for the CT-guided infiltration were recorded.Conclusion: CT-guided pudendal nerve block at the sacrospinous ligament and the Alcock's canal was effective in improving premature ejaculation. Therefore, pudendal nerve entrapment may be a curable cause of sensory premature ejaculation.

Wei S, Wu C, Yu B, Ma M, Qin F, Yuan J. Advantages and limitations of current premature ejaculation assessment and diagnostic methods: a review. Transl Androl Urol 2020; 9:743-757. [PMID: 32420180 PMCID: PMC7215025 DOI: 10.21037/tau.2019.12.08] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Accepted: 11/29/2019] [Indexed: 02/05/2023] Open
Abstract
Premature ejaculation (PE) is the most common male sexual dysfunction worldwide. Characteristic symptoms of PE are unexpected, rapid, complete ejaculation, which negatively impacts the sexual act for both sexual partners. Despite the existence of a definitive PE classification system and various diagnostic tools, diagnosing PE is still challenging due to the limitations associated with the assessment of this condition. Hence, it is necessary to review the diagnostic methods and processes of the physical examination that are currently performed in the medical setting. It is also important to analyze any controversial results of each main PE assessment method and propose novel diagnostic and assessment methods. To date, it is important to verify the accuracy of the PE evaluation method due to the ambiguity of previous definitions and proven invalidity of current examining techniques. Clinical diagnosis is based mainly on the patient history, patient-reported outcome scores, and diagnostic tools. Introduction of intravaginal ejaculatory latency time, penile biothesiometry, and the electrophysiological test provided objective means of evaluating PE. Due to the controversial and inconclusive findings in PE psychogenic and neurogenic etiology, utilizing a single parameter to describe and qualify PE using the aforementioned diagnostic methods provides valuable, but insufficient information for PE diagnosis. There is still a lack of a feasible and plausible means of objective measurement to evaluate the ejaculatory latency and control over ejaculation. Consequently, a comprehensive penile stimulation that simulates sexual intercourse could be useful to record intensity and duration parameters before the ejaculatory threshold, providing a more accurate method of describing and diagnosing PE versus a single chronological observation.

Abstract
OBJECTIVE Premature ejaculation (PE) is regarded as one of the most common male sexual dysfunctions. This review introduced several pharmaceutical and surgical methods for the management of PE. The definition, etiology, behavioral, and psychological therapy of PE were also discussed. DATA SOURCES "Premature," "ejaculation," or "sexual dysfuction" were used as the medical subject headings (MeSH) to obtain relevant articles before June 2019 on Pubmed, Google Scholar and CNKI. Most articles used were written in English and several Chinese articles were also cited. STUDY SELECTION Full-text articles of retrospective/prospective/randomized controlled trials were analyzed. Animal experiments and letters were excluded. RESULTS There are four PE sub-types: lifelong PE, acquired PE, natural variable PE, and subjective PE. Behavioral therapy, psychotherapy, medication, topical anesthetics, and surgery are currently used for the treatment of PE. However, all the above treatments have limitations. Therefore, novel ways should be investigated to more efficiently control PE. CONCLUSIONS The pharmaceutical therapy that is currently being used in clinical practice for the management of PE is still the main choice globally due to its good efficacy. Surgery may be a choice for patients who are resistant to medication. However, it should be performed cautiously.

Abstract
The incidence of premature ejaculation (PE) has been on the rise over the years. Thus, significant research efforts have been directed toward understanding the pathogenesis and hence treatment of PE. Here, we performed a comprehensive analysis of the worldwide trends in research outputs in the field of PE. This study investigated the universal findings of previous PE studies and the trending issues surrounding the condition. We employed the Web of Science Core Collection for data collection. The Excel (2016) and CiteSpace IV were used for information analysis. The information was categorized using journal names, institutions, research frontiers, citation reports, regions/countries, and authors. A sum of 886 publications concerning PE between 2008 and 2018 were identified as of July 6, 2019. The highest number of publications was identified in the Journal of Sexual Medicine published. The United States of America (USA) had the highest number of publications and H-index value. The highest co-citations were from Waldinger MD. The most common keyword was 'drug treatment'. A steady pattern was observed for PE publications done between the period of 2008-2018. Thus, the USA is at the forefront of research on PE research. The interesting advanced research frontiers were drug treatment, circumcision, and sertraline.

Abstract
To explore the efficacy of regular penis-root masturbation (PRM) versus Kegel exercise (KE) in the treatment of primary premature ejaculation (PPE). This study was a prospective quasi-randomised controlled trial. Thirty-seven heterosexual males with PPE were selected according to the time sequence of outpatient consultations and the preliminary results of a pre-experiment and were assigned to an PRM group and a KE group. Differences in intravaginal ejaculatory latency times (IELTs) and premature ejaculation diagnostic tool (PEDT) scores were compared between the two groups. The study was approved by the Ethics Committee of the First Affiliated Hospital of Guangxi Medical University. Among the 37 PPE patients, 18 performed PRM and 19 patients performed KE. The IELTs of patients who performed PRM and KE were significantly prolonged before treatment, and the difference after treatment was statistically significant (p < .05). Compared with the KE group, the IELT prolongation effect in the PRM group was more significant PRM (p < .05). The PEDT scores of patients after performing PRM and KE were significantly lower than those before performing these exercises (p < .05). Compared with the KE group, the PEDT scores of the PRM group exhibited a greater decrease (p < .05). Thus, both PRM and KE have therapeutic effects on PPE. Compared with KE, PRM is more effective in the treatment of PPE.

Abstract
Premature ejaculation (PE) is a highly prevalent male sexual dysfunction that is often neglected, presenting a currently unmet therapeutic need. The classification of PE has historically been varied and at times ambiguous, contributing to inaccurate prevalence estimates. This review uses the International Society for Sexual Medicine (ISSM) definition of PE, which includes reduced ejaculatory latency, lack of control and associated negative personal consequences. Patient assessment and management options differ depending on the classification of PE and it is the role of the clinician to appropriately classify patients and be aware of the correct management strategies. This review provides an overall background of PE in terms of classification and underlying physiology, patient assessment and management strategies along with the scientific rationale for treatment. Patients with lifelong and acquired PE are most likely to benefit from combination therapy of pharmacological treatment in the form of selective serotonin re-uptake inhibitor dapoxetine, psychosexual behavioural therapy and psychological therapy.
