Liu J, Bao T, Wang Q, Jiang H, Zhang X. Stigma and its associations with self-confidence and sexual relations in 4 types of premature ejaculation. Basic Clin Androl 2024; 34:11. [PMID: 38951750 PMCID: PMC11218248 DOI: 10.1186/s12610-024-00226-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 04/22/2024] [Indexed: 07/03/2024] Open
Abstract
BACKGROUND Although men with premature ejaculation (PE) always show more negative emotions, including embarrassment, guilt and worry, this may be related to the stigma of PE. To investigated stigma and its associations with self-confidence and sexual relations in 4 PE syndromes, a survey was conducted in our hospital from December 2018 to December 2019 among 350 men with self-reported PE and 252 men without self-reported PE. The stigma, self-confidence and sexual relations were assessed by the Social Impact Scale (SIS) and Self-Esteem and Relationship questionnaire (SEAR), respectively. Ejaculation control, sexual life satisfaction and distress caused by PE were evaluated by the Index of PE. RESULTS Men with self-reported PE had higher internalized shame and social isolation scores and lower SEAR scores than control subjects. The highest score of internalized shame and social isolation and the lowest score of SEAR appeared in men with lifelong PE (LPE). After age adjustment, the positive relationships were stronger between distress about PE and internalized shame. Whereas, the stronger negative associations were found between social isolation and sexual satisfaction. The strongest association was observed between social isolation and sexual relationship. Therefore, the stigma associated with PE adversely affects the self-confidence, self-esteem, and sexual relationships of men with PE. CONCLUSION Men with PE, especially LPE, have a high level of stigma and disharmonious sexual relations, and often lack self-confidence and self-esteem, which have a certain negative impact on their physical and mental health and life. These will be the key issues to be considered when we formulate a personalized treatment plan for PE.

Rowland DL, Tamas S, Hevesi K. Updating, correcting, and calibrating the narrative about premature ejaculation. Sex Med Rev 2024; 12:401-410. [PMID: 38798049 DOI: 10.1093/sxmrev/qeae036] [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: 03/14/2024] [Revised: 04/20/2024] [Accepted: 05/06/2024] [Indexed: 05/29/2024]
Abstract
INTRODUCTION The narrative surrounding premature ejaculation (PE) has developed and solidified over the past 25 years. Unfortunately, portions of that narrative are outdated and do not reflect more recent conceptualizations or empirical findings regarding this disorder. OBJECTIVE In this review we sought to identify existing narratives about PE in need of updating and to provide revised narratives based on the recent research literature. METHOD Five PE narratives in need of revision were identified, including: the prevalence of PE, age-related differences in PE prevalence, a validated ejaculation latency (EL) for diagnosing PE, differences between lifelong and acquired PE subtypes, and the application of PE definitions beyond penile-vaginal intercourse. Extensive literature searches provided information supporting both the original narrative and the need for a revised narrative based on both consideration of more recent studies and reinterpretation of studies conducted since the establishment of the original narratives. RESULTS For each selected topic, the prevailing narrative based on the extant literature was first presented, followed by discussion of accumulating evidence that challenges the existing narrative. Each section ends with a suggested revised PE narrative. In 2 instances, the revised narrative required significant corrections (eg, PE prevalence, validated EL for diagnosing PE); in 2 instances, it expanded on the existing narrative (eg, PE subtype differences, inclusion of partnered sexual activities beyond penile-vaginal intercourse); and in 2 other instances, it backed off prior conclusions that have since required rethinking (eg, age-related changes in PE, PE subtype differences). Finally, a brief review of the 3-pronged criteria for PE (EL, ejaculatory control, and bother/distress) is presented and discussed. CONCLUSION This review reiterates the dynamic state of research on PE and demonstrates the need for and value of ongoing research that not only addresses new issues surrounding this dysfunction but also challenges and revises some of the existing narratives about PE.

Abstract
Sexual dysfunction is common in males with chronic kidney disease (CKD), but yet the prevalence and specific relationship between CKD and sexual dysfunction, especially premature ejaculation (PE), remain to be investigated in China; This study aims to examine the prevalence and association between CKD and sexual dysfunction in male patients in China; In this cross-sectional, non-interventional, observational study conducted at a single center. 72 male patients with CKD were enrolled. Data collection included socio-demographic information, assessments via the 5-item version of the International Index of Erectile Function (IIEF-5), the Chinese version of the Premature Ejaculation Diagnostic Tool, the Patient Health Quentionnnaire-9 and the General Anxiety Disorder-7. Data analysis was performed using R version 3.5.2 and SPSS software version 25.0; Among the 72 CKD patients, 56.9% experienced erectile dysfunction and 29.2% had PE. Various factors including estimated Glomerular Filtration Rate, Albumin-to-Creatinine Ratio, psychological aspects, medication use were found to be associated with sexual dysfunction in these CKD patients; Sexual dysfunction is prevalent in males with CKD and is, influenced by multiple factors. It is important for clinicians to focus on sexual dysfunction in this patient group and further investigate its underlying mechanisms.

World J Urol 2024; 42:218. [PMID: 38581447 PMCID: PMC10998814 DOI: 10.1007/s00345-024-04899-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Accepted: 02/21/2024] [Indexed: 04/08/2024] Open
Abstract
PURPOSE To evaluate the safety and efficacy of botulinum-A toxin injections into the bulbospongiosus muscle for cases of lifelong drug-resistant premature ejaculation (PE). METHODS Ninety-eight outpatients diagnosed with lifelong PE were randomly assigned to two groups: the botulinum-A toxin group comprising forty-nine patients and the placebo (saline) group also consisting of forty-nine patients. A 100 U botulinum-A toxin was diluted into 10 cc of saline, with 5 cc injected into one side of the muscle (botulinum-A toxin group) guided by ultrasound to distribute across most muscle fibers. The same technique was applied using the same volume of saline injected into the bulbospongiosus muscle. Intravaginal ejaculatory latency time (IELT), scores from the premature ejaculation profile (PEP), Premature Ejaculation Diagnostic Tool (PEDT), International Index of Erectile Function (IIEF), and recording of any complications were obtained. Follow-ups occurred at 1-, 3-, and 6-month post-procedure. RESULTS Cases receiving injections of botulinum-A toxin into the bulbospongiosus muscle showed notably extended intravaginal ejaculatory latency times compared to their initial performance after treatment. In addition, there were enhancements in PEP scores, and notably, no significant complications were reported. Conversely, the bilateral injection of saline into the bulbospongiosus muscle did not demonstrate any impact on ejaculation latencies. CONCLUSION Our study demonstrated that the injection of botulinum-A toxin into the bulbospongiosus muscle can serve as a safe and effective option for treating PE. Nonetheless, its clinical application warrants further studies involving larger sample sizes and longer follow-up periods.

Abstract
OBJECTIVE To determine whether men with lifelong vs acquired premature ejaculation (PE) subtypes differ on their estimated ejaculation latencies (EL) and related sexual, relationship, and behavioral parameters. METHODS Of 2679 men who responded to an online multinational survey about sexual health and met inclusion criteria, 540 reported "probable" or "definite" PE, as assessed by the Premature Ejaculation Diagnostic Tool. Lifelong and acquired PE subtypes were compared on multiple measures related to EL, as well as on sets of demographic, diagnostic, relationship, sexual behavioral, and sexual functioning measures during both partnered sex and masturbation. RESULTS Nearly 73% of men with PE in this sample reported the lifelong subtype. No differences emerged in EL measures between subtypes, even when parsed according to age. Specifically, men 37years or under with either definite lifelong or acquired PE reported ELs of 1.9 minutes (SD=1.3). For men over 37, lifelong ELs were 2.0 minutes (SD=1.3), acquired ELs 2.4 minutes (SD=1.4). While the lifelong subgroup was younger and reported lower erectile functioning, these differences occurred only in the probable PE group and not the definite PE group. CONCLUSION Our data do not support different EL criteria for men with acquired vs lifelong PE, as suggested by several professional definitions. Furthermore, differences in age and erectile functioning between the groups, often reported in clinical samples though not in our definite PE group, may be an artifact of the general health/patient characteristics that lead such men to seek medical assistance.

Repetitive transcranial magnetic stimulation via the hippocampal brain-derived neurotrophic factor-tyrosine kinase receptor B pathway to affect sexual behavior and neuroplasticity in rapid ejaculation rats. Andrology 2024.

Abstract
BACKGROUND Premature ejaculation (PE) is the most prevalent sexual dysfunction among men. Eejaculation involves a complex nervous mechanism in which the ejaculatory centers play a key role in modulating sperm emission. Although treatment possibilities span from psychotherapy to pharmacological approaches, results show inconsistent efficacy. In this context, the emergence of repetitive transcranial magnetic stimulation (rTMS) as a non-invasive neuromodulatory approach represents a compelling avenue for potential therapeutic exploration. OBJECTIVE To investigate whether high-frequency transcranial magnetic stimulation can modulate the ejaculatory behavior of rats with rapid ejaculation by altering neurotransmitter levels and neuroplasticity in the hippocampus. METHODS Rats have been screened for rapid ejaculation by observing behavioral indices of mating, and subsequently divided into two groups. The intervention group was administered with a 10 Hz rTMS stimulation, whereas the control group received a sham procedure. Upon the delivery of rTMS, we investigated ejaculation latency (EL), the hippocampal 5-hydroxytryptamine (5-HT) concentration, brain-derived neurotrophic factor (BDNF), synaptophysin (SYN), and postsynaptic density protein 95 (PSD95) expressions, as well as BDNF-receptor tyrosine kinase receptor B (TrkB) pathway upregulation. RESULTS After 14 days, EL was increased in the intervention group compared with the control group. 5-HT concentration in the hippocampal region was increased, and high-frequency rTMS activated the BDNF and TrkB pathways, including phosphorylation of cAMP response element-binding protein (CREB), and upregulated the transcription and protein expression of SYN, and PSD95. CONCLUSION RTMS upregulates BDNF, SYN, and PSD95 expression through activation of the BDNF-TrkB pathway and increases brain 5-hydroxytryptamine thereby regulating neuroplasticity and improving ejaculation.

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 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
Purpose of Review Direct-to-consumer telemedicine has vastly expanded in recent years, and urologic conditions are a common target for these companies. We aim to identify the urologic conditions being treated by direct-to-consumer telemedicine platforms and review the feasibility of adherence to evidence-based practice guidelines via this relatively new healthcare model. Recent Findings Erectile dysfunction, premature ejaculation, testosterone deficiency, and male infertility are being treated with direct-to-consumer telemedicine. Such platforms treating erectile dysfunction perform modestly in practice guideline adherence. Guidelines-based treatment of other urologic conditions via telemedicine is feasible, however, the treatment of these conditions through popular direct-to-consumer telemedicine platforms is largely unstudied. Summary The impact of direct-to-consumer telemedicine on the field of urology is vast and likely to continue to grow. Future studies should inspect direct-to-consumer telemedicine companies’ practice patterns and treatment outcomes to ensure the field’s standards of care are being met. Guidelines specific to the treatment of various urologic conditions via telemedicine are needed.

Abstract
Glandular augmentation (GA) with hyaluronic acid (HA) is a newly developed, minimally invasive therapy for patients with premature ejaculation (PE); however, evidence supporting its efficacy is scarce. To provide a comprehensive profile of GA with HA gel in managing PE, 184 patients with PE who received GA with HA gel therapy from October 2017 to November 2019 were included and followed up for 1 year. The Fan technique was applied. Intravaginal Ejaculation Latency Time (IELT), Chinese Index of Premature Ejaculation-5(CIPE-5) and Visualised Satisfaction Index (VSI) of sexual experience were assessed at initial and 1-, 3-, 6- and 12-month post injection. A total of 71 patients with primary PE (pPE, 38.6%) and 113 patients with acquired PE (aPE, 61.4%) were enrolled. The mean IELT increased to 100.7 ± 43.2 s(p < .05) for pPE patients and 359.2 ± 87.1 s (p < .05) for aPE patients 1-month post injection and remained significantly higher at the end point with acceptable attenuation. The mean CIPE-5 score increased to 17.6 ± 6.4 (p < .05) in the 1st month and remained steady. The VSI scores increased to 6.6 ± 1.0 (p < .05) for patients with pPE and 7.7 ± 1.2 (p < .01) for patients with aPE. Increments in VSI in patients with aPE were significantly higher than those in patients with pPE (p < .01). No severe complications were noted. GA with HA may be an effective and safe method to treat PE. Patients with acquired PE were also more satisfied post treatment.

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
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.

Int J Impot Res 2022:10.1038/s41443-022-00554-8. [PMID: 35314817 DOI: 10.1038/s41443-022-00554-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 02/24/2022] [Accepted: 03/03/2022] [Indexed: 11/09/2022]
Abstract
A eutectic mixture of prilocaine/lidocaine spray (Fortacin™, Recordati, Milan, Italy) has been approved for the management of patients affected by life-long premature ejaculation (PE), but to date, there is a lack of dose- or time-finding studies in the literature that indicate the best method of intake to optimize treatment outcomes. In this multicentre, randomized, two-phase study, we aimed to compare, in terms of treatment effectiveness (primary objective) and safety (secondary objective), different treatment regimens (various doses and times of drug delivery) of Fortacin™ in 91 patients affected with lifelong PE who were recruited at four different centres and randomized (1:1:1 ratio) into three different groups. The study included two phases: during the first phase (focused on time-finding), the same drug dose (three sprays) was taken at different intervals before intercourse (5, 15, 30 min). In the second phase (focused on dose finding), different drug doses (1, 3, 5 sprays) were taken at the same interval before intercourse (5 min). The main outcome measure instruments were self-measured intravaginal ejaculation latency time (sm-IELT), the premature ejaculation diagnostic tool (PEDT), and the International Index of Erectile Function-5 (IIEF-5). Furthermore, patients were asked to report any side effects that appeared during the study period. Our main study findings showed that the treatment regimen with three sprays of Fortacin™ administered 5 min before sexual intercourse showed the best results in terms of ejaculation time and control (Phase I, IELT 221 ± 3.4, PEDT 7.7 ± 0.3; Phase II, IELT 213 ± 4.9, PEDT 7.8 ± 0.4) with a safety profile that was identical to other treatment regimens. Based on these data, patients who are prescribed Fortacin™ should stick to this regimen to optimize treatment results.

Abstract
BACKGROUND There are several problems with diagnostic criteria for premature ejaculation (PE) that lack objectivity, clarity and precision. They hamper accurate determination of PE prevalence estimates, investigations into the etiology of the dysfunction, impact on partners, development of validated Patient Reported Outcomes, regulatory authority oversight, and which men might benefit from specific treatment interventions. AIM We sought to review, analyze and comment on the evolution of the definitions of PE and offer suggestions for future directions for PE definitions. Our goal is to propose strategies whereby the criterion sets are useful to researchers, clinicians and governmental oversight agencies alike and bring harmony and scientific rigor among the conflicting and confusing definitions. METHODS There are several premature ejaculation definitions published in the peer reviewed medical literature. The PUBMED electronic database from 1970 to 2021 was searched for published definitions. Search terms included the medical subject headings of premature ejaculation, definition and diagnosis. In chronological order, Table 1 lists the various diagnosis and criteria sets for PE. We discuss the process by which constructs, which make up diagnostic criteria sets, are operationalized and validated. RESULTS We review definitions of PE beginning with Masters and Johnson's focus on partner orgasmic attainment and move through the nebulous and subjective criterion sets found in the early Diagnostic and Statistical Manuals and International Classification of Disease series, to the more evidenced-based definitions found in International Society of Sexual Medicine, Diagnostic and Statistical Manuals-5 and the American Urological Association (AUA) definitions. Additionally, we discuss how constructs and criteria sets have been adopted to minimize errors of inclusion and exclusion in defining disease/dysfunction. STRENGTHS AND LIMITATIONS This manuscript offers a careful chronological analysis of the published definitions of PE. This historical lens allows the reader to perceive the shifting science underlying the development of PE definitions. The manuscript is limited regarding our comments on acquired PE as evidenced-based research is incomplete. CONCLUSION Over the past 50 years there has been considerable forward momentum in defining PE based on well conducted scientific studies. We support the American Urological Association's modification in Intravaginal ejaculatory latency time to 2-minutes for lifelong PE, concur with the 11th revision of the International Classification of Diseases recommendation for changing the terminology from premature ejaculation to early ejaculation. We also recommend ongoing validation of definitions, moving away from the current heterosexist definition of PE based on penile-vaginal sex and urge further population based research into acquired PE to develop stronger evidenced-based criterion sets for this subtype.

Abstract
INTRODUCTION Men suffering from one sexual problem sometimes report having another sexual problem, but few studies have determined concordance rates among dysfunctions in non-clinical samples. AIM This study determined comorbidities among sexual dysfunctions based on an internet convenience sample of 4432 men from Hungary, the USA, and other world regions that visit social media fora. METHOD Participants completed an online 55-item questionnaire that included questions assessing erectile dysfunction (ED), premature ejaculation (PE), delayed ejaculation (DE), and lack of sexual interest (LSI). MAIN OUTCOME MEASURES Concordance rates and odds ratios among sexual dysfunctions. RESULTS Approximately 8% of men suffered from two or more sexual problems; men with a severe sexual problem were significantly more likely to suffer from a second sexual problem; concordance between PE and erectile dysfunction ranged from 23-29%, with subtypes of lifelong vs acquired PE showing patterns similar to one another; and most men with delayed ejaculation reported minimal problems with LSI, although LSI was generally key to understanding all other dysfunctions. CONCLUSION The percentage of men with one sexual problem having a second sexual problem was substantial, ranging from 23-40%. These findings will help clinicians better understand the intertwined nature of sexual problems and assist them in developing management protocols that address concomitant inadequacies in sexual response.

Abstract
The gold-standard method for diagnosing arteriogenic erectile dysfunction (AED) is the penile Doppler ultrasonography. We proposed a novel method for predicting AED using ultrasonic shear wave elastography (SWE) considering that the former was invasive and variable. A total of 98 male patients were enrolled in our study, referred for ED between December 2018 and October 2020. For comparison, we also included 42 volunteers from the Healthy Physical Examination Center of our hospital. The Penile Doppler Ultrasonography (PDU) and SWE were performed for all patients with the intracavernosal injection (ICI). We named three groups as AED group, nonvascular ED group and healthy controls group. No statistically significant differences were found among the three groups in terms of demographic and clinical characteristics. There were no significant differences in IIEF-5 between AED and nonvascular ED. A significant (r = 0.642, p < 0.0001) positive correlation between flaccid and erectile SWE was observed. With a cut-off value of 13.45 KPa, the area under curve, specificity, and sensitivity of the SWE values under the flaccid state in distinguishing AED from healthy subjects were 0.867, 0.786 and 0.896 respectively. The SWE value in the flaccid state can distinguish the AED from healthy subjects.

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
Introduction Premature ejaculation (PE) is widely regarded as one of the most common sexual dysfunctions in men. The neurobiogenesis of PE is complex and involves the serotoninergic (5-HT) system. Aim In this study, we investigated whether polymorphisms in the tryptophan hydroxylase 2 (TPH2) gene were associated with lifelong PE (LPE). Methods A total of 121 men diagnosed with LPE were recruited from our outpatient clinics and 94 healthy controls from the health examination center. Intravaginal ejaculation latency time (IELT) was measured using a stopwatch. The PE diagnostic tool (PEDT) data were collected at the same time. All subjects with LPE and healthy controls were genotyped for polymorphisms in the TPH2 gene. Allele and genotype frequencies of single-nucleotide polymorphisms (SNPs) were compared between the patients and controls. Main Outcome Measure The main outcome measures are IELT and PEDT to diagnose LPE. The association of LPE with TPH2 gene polymorphisms in these areas was investigated. Results The IELT, PEDT scores, and education levels in the LPE group were significantly different from those in the control group. Statistically significant differences were found in the SNPs of SNV019 and rs4290270. The frequencies of the G allele and G/A genotype of SNV019 were significantly higher in the patients with LPE than in the controls (P = .045 and .037, respectively). The A allele and A/A genotype of rs4290270 were more frequent in the patients with LPE than in the controls (P = .037 and .049, respectively). In the dominant model of inheritance, the SNV019 polymorphism in the patients with LPE was significantly different from that in the controls (odds ratio [95% confidence interval] = 2.936 [1.066–8.084], P = .037). In men with LPE, there was no statistically significant association between genotype and median IELT. Conclusion The SNPs SNV019 and rs4290270 of the TPH2 gene seemed to be associated with LPE in the Han population. Men with the A allele of SNV019 or the T allele of rs4290270 may be less likely to suffer from LPE. Fu X, Zhang X, Jiang T, et al.

Abstract
The premature ejaculation diagnostic tool (PEDT) is a brief diagnostic measure to assess premature ejaculation (PE). However, there is insufficient evidence regarding its validity in the new evidence-based-defined PE. This study was performed to evaluate the validity of PEDT and its association with IIEF-15 in different types of evidence-based-defined PE. From June 2015 to January 2016, a total of 260 men complaining of PE and defined as lifelong PE (LPE)/acquired PE (APE) according to the evidence-based definition from Andrology Clinic of the First Affiliated Hospital of Anhui Medical University, along with 104 male healthy controls without PE from a medical examination center, were enrolled in this study. All individuals completed questionnaires including demographics, medical and sexual history, as well as PEDT and IIEF-15. After statistical analysis, it was found that men with PE reported higher PEDT scores (14.28 ± 3.05) and lower IIEF-15 (41.26 ± 8.20) than men without PE (PEDT: 5.32 ± 3.42, IIEF-15: 52.66 ± 6.86, P < 0.001 for both). It was suggested that a score of ≥9 indicated PE in both LPE and APE by sensitivity and specificity analyses (sensitivity: 0.875, 0.913; specificity: 0.865, 0.865, respectively). In addition, IIEF-15 were higher in men with LPE (42.64 ± 8.11) than APE (39.43 ± 7.84, P < 0.001). After adjusting for age, IIEF-15 was negatively related to PEDT in men with LPE (adjust r = -0.225, P < 0.001) and APE (adjust r = -0.378, P < 0.001). In this study, we concluded that PEDT was valid in the diagnosis of evidenced-based-defined PE. Furthermore, IIEF-15 was negatively related to PEDT in men with different types of PE.

Abstract
INTRODUCTION Andrology focuses in male sexual and fertility diseases. Its referral should be thoughtful and tailored in order to select the correct cases. OBJECTIVES The aim of this work was to evaluate the referral to our department and improvement points. MATERIAL AND METHODS A retrospective analysis was performed of the Andrology consults between January 2014 and December 2015. RESULTS We evaluated 96 of the 102 consults performed. About 60% of patients were referred with erectile dysfunction complaints, 15% with penile curvature and 8% with ejaculatory dysfunction. About 27% had previously tried phosphodiesterase 5 inhibitor, and 40% lacked recent metabolic workup. DISCUSSION The high prevalence of sexual complaints coupled with a high number of naïve patients could be due to difficulties by the referral doctors when analyzing and characterizing male sexual dysfunction according to the current sexual response cycle model. The lack of patient categorization accordingly to Princeton criteria (III) shows the difficulties found when selecting patients to start the first line of treatment for erectile dysfunction. CONCLUSION Sexual dysfunction are highly prevalent in the general population. Healthcare providers should improve diagnostic and treatment skills in this field of Urology.

Abstract
Myriad biological factors have been proposed to explain premature ejaculation (PE). However, data correlating PE with seminal vesicles (SVs) are sparse. The study aimed to evaluate the relationship between the size of SV and PE. The cross-sectional study included 44 outpatients with PE and 44 volunteers without PE, and the size of SV was compared. Self-estimated intravaginal ejaculatory latency time, the Premature Ejaculation Diagnostic Tool (PEDT), the International Index of Erectile Function-15, and the National Institutes of Health-Chronic Prostatitis Symptom Index were used for assessment of symptoms. Compared to the control group, the PE group had significantly higher mean anterior-posterior diameter (APD) of SV (P < 0.001). The optimal mean APD of SV cutoff level was 9.25 mm for PE. In the PE group, PEDT was also higher with a mean APD of SV ≥9.25 mm compared with mean APD of SV <9.25 mm. PEDT was significantly correlated with the mean APD of SV (r = 0.326, P = 0.031). The seminal plasma proteins were compared between six PE and six matched control cases by mass spectrometry and it was shown that 102 proteins were at least 1.5-fold up- or down-regulated. Among them, GGT1, LAMC1, and APP were significantly higher in the PE group. These results indicated that men with a larger mean APD of SV might have a higher PEDT score. Transrectal ultrasound of SV should be considered in the evaluation of patients with premature ejaculation. SV might be a potential target for the treatment of patients with PE and ultrasound change in SV.

Abstract
Penile hypersensitivity plays an important role in premature ejaculation (PE), but differences in penile sensitivity among subtypes of PE are unknown. Therefore, we compared penile sensory thresholds in PE subtypes of lifelong and acquired PE, PE with and without erectile dysfunction (ED), PE with an intravaginal ejaculation latency time ≤1 min and >1 min, and PE with and without orgasmic pleasure perceptual dysfunction. During August 2014 to January 2016, 136 patients with PE were included. Penile warm, cold, and vibratory thresholds were measured. Data of clinical characteristics, sexual life, Premature Ejaculation Diagnostic Tool (PEDT) score, and the 5-item version of the International Index of Erectile Function (IIEF-5) score were collected. Vibratory thresholds of the PE with ED group were higher in the right coronal sulcus (median amplitude: 4.92 vs 3.65 μ m, P = 0.02) and the right penile shaft (median amplitude: 3.87 vs 3.30 μ m, P = 0.03), while differences in penile sensory thresholds between other subtypes were not significant. The median PEDT score was lower in the PE without ED group (12 vs 14, P < 0.001). The IIEF-5 and PEDT scores were negatively correlated (r = -0.29, P < 0.001). Patients with orgasmic pleasure perceptual dysfunction had a lower median IIEF-5 score (20 vs 21, P = 0.02). Patients with PE and ED had lower penile sensitivity, and ED was associated with more severe symptoms and weaker orgasmic pleasure perception. In men with PE, management of comorbid ED is necessary. In case of side effects in erectile function, topical anesthetics should be cautiously used in men with PE and ED.

Abstract
Objectives This study aimed to determine the prevalence of premature ejaculation and its associated factors among men attending a primary healthcare clinic in Kota Bharu, Kelantan, Malaysia. Methods A cross-sectional study was conducted on 18- to 60-year-old sexually active men during at least the past 6 months. Patients with unstable psychiatric illnesses, mental retardation, and illiteracy were excluded. A questionnaire on sociodemographic factors, Malay version Premature Ejaculation Diagnostic Tool, and Malay version International Index Erectile Function-5 were distributed. Premature ejaculation was defined as a Premature Ejaculation Diagnostic Tool score of 9 and above. Descriptive analysis and simple and multiple logistic regression analyses were performed using SPSS version 22. Results A total of 294 of 313 eligible men responded, with a response rate of 93.9%. The prevalence of premature ejaculation was 21.4% (n = 63). The multiple logistic regression analysis showed that mild [adj. OR (95% CI): 5.6 (1.89, 16.91); P = 0.002], mild-moderate [adj. OR (95% CI): 8.2 (2.72, 24.46); P < 0.001], and moderate-severe [adj. OR (95% CI): 6.0 (1.15, 31.23); P = 0.03] erectile dysfunctions were significantly associated with premature ejaculation. Conclusion Promoting awareness on premature ejaculation among the society and healthcare providers would increase the detection rate of this disorder. Such data will also help provide better sexual health services. Research on the underlying comorbidities among men with premature ejaculation is recommended owing to its negative impact on psychosocial aspects and quality of life.

Abstract
Evidence-based definitions improve clinical practice and research. Nonetheless, the International Society of Sexual Medicine (ISSM) and the American Psychiatric Association's (DSM-5) definitions regarding lifelong and acquired premature ejaculation (PE) and delayed ejaculation (DE) require reexamination. Existing Intravaginal Ejaculation Latency Time (IELT) evidence, the ISSM position papers, and articles both supporting and critiquing the ISSM's definitions were reviewed. Disproportionately, the findings from those studies document that the majority of men's IELT range is approximately 4 to 10 minutes. Such robust quantitative evidence should become the basis for determining the temporal criterion when defining both PE and DE. Any bilateral deviation from that majority's ∼4- to 10-minute IELT range should meet the qualification for the temporal diagnostic criterion. However, for a man to be diagnosed with a disorder, a licensed health-care clinician (HCC) must also determine that the man suffers from "lack of control" and "distress." Diagnosis would include subtyping Lifelong or Acquired, Global or Situational, similar to the ISSM guidelines and specifying mild, moderate, or severe-similar to DSM-5 requirements. "Control" and "distress" should trump latency and convey greater weight in the diagnostic process. Loosened latency criteria could result in false positive diagnoses; however, requiring a licensed HCC to evaluate control and distress reduces that risk.

Abstract
The aim of this study was to investigate the relationship between metabolic syndrome (MetS) and acquired premature ejaculation (PE). A total of 100 patients with acquired PE and 100 control cases were enrolled in the study. After obtaining a detailed medical history, anthropometric (weight, height and waist circumference) and blood pressure measurements were performed. Ejaculation and erection functions were evaluated by Premature Ejaculation Diagnostic Tool (PEDT) and International Index of Erectile Function-5 (IIEF-5), respectively. Self-estimated intravaginal ejaculatory latency time (IELT) of the participants was recorded. Fasting blood samples were taken for biochemical and hormonal work-up. The median PEDT scores were 16 (9-22) and 4.5 (2-8) in acquired PE and control groups, respectively (P<0.001). The mean estimated IELT values in PE patients and controls were 36.1±46.5 versus 488.2±313.8 s (P<0.001). MetS was diagnosed in 51 patients (51%) in the PE group and 24 (24%) participants in the control group (P<0.001). A significant negative correlation was observed between the components of MetS and estimated IELT, except for diastolic blood pressure. Moreover, there was a significant positive correlation between the all components of MetS and total PEDT score, except for fasting blood glucose and high-density lipoprotein cholesterol (HDL) levels. Logistic regression analysis revealed that, except blood pressure and HDL levels, MetS components were significant risk factors for PE after adjusting for age and total testosterone. In conclusion, MetS is associated with acquired PE.

Abstract
Introduction In 2014, new evidence-based definitions of lifelong premature ejaculation (LPE) and acquired premature ejaculation (APE) were proposed by the International Society for Sexual Medicine. Based on the new PE definitions, the prevalence of and factors associated with LPE and APE have not been investigated in China. Aim To evaluate the prevalence of and factors associated with LPE and APE in men with the complaint of PE in China. Methods From December 2011 to December 2015, a cross-sectional field survey was conducted in five cities in the Anhui province of China. Questionnaire data of 3,579 men were collected in our database. The questionnaire included subjects' demographic information and medical and sexual histories. Men who were not satisfied with their time to ejaculate were accepted as having the complaint of PE. Men with the complaint of PE who met the new definition of PE were diagnosed as having LPE or APE. Main Outcome Measures New definition of LPE and APE. Results Of 3,579 men who completed the questionnaire, 34.62% complained of PE. Mean age, body mass index, and self-estimated intravaginal ejaculatory latency time for all subjects were 34.97 ± 9.02 years, 23.33 ± 3.56 kg/m2, and 3.09 ± 1.36 minutes, respectively. The prevalences of LPE and APE in men with the complaint of PE were 10.98% and 21.39%, respectively. LPE and APE were associated with age, body mass index, and smoking and exercise rates (P < .001 for all comparisons). Men with APE reported more comorbidities than men with LPE, especially in the presence of hypertension, diabetes mellitus, and heart disease (P < .001 for all comparisons). Conclusion In this study, the prevalences of LPE and APE in men with the complaint of PE were 10.98% and 21.39%, respectively. Patients with APE were older and more likely to smoke, had more comorbidities, and had a higher body mass index than patients with LPE.

Abstract
Large well-designed clinical efficacy and safety randomized clinical trials (RCTs) are required to achieve regulatory approval of new drug treatments. The objective of this article is to make recommendations for the criteria for defining and selecting the clinical trial study population, design and efficacy outcomes measures which comprise ideal premature ejaculation (PE) interventional trial methodology. Data on clinical trial design, epidemiology, definitions, dimensions and psychological impact of PE was reviewed, critiqued and incorporated into a series of recommendations for standardisation of PE clinical trial design, outcome measures and reporting using the principles of evidence based medicine. Data from PE interventional studies are only reliable, interpretable and capable of being generalised to patients with PE, when study populations are defined by the International Society for Sexual Medicine (ISSM) multivariate definition of PE. PE intervention trials should employ a double-blind RCT methodology and include placebo control, active standard drug control, and/or dose comparison trials. Ejaculatory latency time (ELT) and subject/partner outcome measures of control, personal/partner/relationship distress and other study-specific outcome measures should be used as outcome measures. There is currently no published literature which identifies a clinically significant threshold response to intervention. The ISSM definition of PE reflects the contemporary understanding of PE and represents the state-of-the-art multi-dimensional definition of PE and is recommended as the basis of diagnosis of PE for all PE clinical trials.

Abstract
The second Ad Hoc International Society for Sexual Medicine (ISSM) Committee for the Definition of Premature Ejaculation defined acquired premature ejaculation (PE) as a male sexual dysfunction characterized by a the development of a clinically significant and bothersome reduction in ejaculation latency time in men with previous normal ejaculatory experiences, often to about 3 minutes or less, the inability to delay ejaculation on all or nearly all vaginal penetrations, and the presence of negative personal consequences, such as distress, bother, frustration and/or the avoidance of sexual intimacy. The literature contains a diverse range of biological and psychological etiological theories. Acquired PE is commonly due to sexual performance anxiety, psychological or relationship problems, erectile dysfunction (ED), and occasionally prostatitis and hyperthyroidism, consistent with the predominant organic etiology of acquired PE, men with this complaint are usually older, have a higher mean BMI and a greater incidence of comorbid disease including hypertension, sexual desire disorder, diabetes mellitus, chronic prostatitis, and ED compared to lifelong, variable and subjective PE.

Abstract
Premature ejaculation (PE) is a poorly understood condition and is considered as the most common sexual disorder in men. The ambiguity surrounding PE is in part due to the difficulty in conducting and interpreting research in the absence of a standardised definition that adequately encompasses the characteristics of these patients. An enhanced awareness of sexual dysfunctions in the recent decades has lead to an increase in scientific research that has challenged the traditional paradigm regarding PE. This has also enabled to establish a universal definition and classification of the disease. A move to a more evidence based approach has improved the clinicians' ability to define those who need medical treatment, as well as perform further research in this complex condition.

Abstract
For many decades it has been thought that lifelong premature ejaculation (PE) is only characterized by persistent early ejaculations. Despite enormous progress of in vivo animal research, and neurobiological, genetic and pharmacological research in men with lifelong PE, our current understanding of the mechanisms behind early ejaculations is far from complete. The new classification of PE into four PE subtypes has shown that the symptomatology of lifelong PE strongly differs from acquired PE, subjective PE and variable PE. The phenotype of lifelong PE and therefore also the pathophysiology of lifelong PE is much more complex. A substantial number of men with lifelong PE not only have PE, but also premature erection and premature penile detumescence as part of an acute hypertonic or hypererotic state when engaged in an erotic situation or when making love. As both erectio praecox, ejaculatio praecox, detumescentia praecox, and the hypererotic state are part of the phenotype lifelong PE, it is argued that lifelong PE is not only a disturbance of the timing of ejaculation but also a disturbance of the timing of erection, detumescence and arousal. Since 1998, the pathophysiology of lifelong PE was thought to be mainly mediated by the central serotonergic system in line with genetic polymorphisms of specific serotonergic genes. However, by accepting that lifelong PE is characterized by the reversible hypertonic state the hypothesis of mainly serotonergic dysfunction is no longer tenable. Instead, it has been postulated that the pathophysiology of lifelong PE is mediated by a very complex interplay of central and peripheral serotonergic, dopaminergic, oxytocinergic, endocrinological, genetic and probably also epigenetic factors. Progress in research of lifelong PE can only be accomplished when a stopwatch is used to measure the IELT and the cut-off point of 1 minute for the definition of lifelong PE is maintained. Current use of validated questionnaires, neglect of stopwatch research, clinically inexperienced investigators and inclusion of anonymous men in a study performed by the Internet endanger the continuation of objective research of lifelong PE.

Abstract
INTRODUCTION Lifelong premature ejaculation (LPE) is the most important ejaculating dysfunction. Relatively little is known about erectile function in this population. AIMS We attempted to evaluate the erectile function of patients with LPE using the International Index of Erectile Function-5 (IIEF-5) to determine if it is sufficiently reliable and accurate to make such an assessment. METHODS A total of 406 patients with LPE were enrolled in our study. The participants voluntarily answered the Premature Ejaculation Diagnostic Tool (PEDT) and IIEF-5 questionnaires and underwent a full history evaluation and clinical examination by doctors. Their answers were converted into data analyzed by a statistic software. MAIN OUTCOME MEASURES The patients were diagnosed with LPE based on the diagnostic criteria and PEDT scores. The intravaginal ejaculation latency time was recorded according to patient self-reports. The IIEF-5 was used to evaluate their erectile function. Thorough history and clinical examination helped doctors make more correct diagnoses of erectile dysfunction (ED). RESULTS Of the 406 patients, 70 (17.24%) patients had ED, as confirmed by doctors. IIEF-5 was accurate for the assessment of the erectile function of LPE patients when the cutoff was decreased to 15.5. Question 5 (1.34 ± 0.53) was the main reason for the drop in the total IIEF-5 score. Questions 1 and 5 shared low consistency with the other three IIEF-5 items, thus they lowered the reliability of the IIEF-5 scores. These questions created a confounding bias that decreased the diagnostic threshold of IIEF-5. However, they could not be removed from the IIEF-5 because they did not reduce its diagnostic accuracy in patients with LPE. CONCLUSIONS Bias from questions 1 and 5 lowered the reliability of the IIEF-5 scores; however, it did not reduce the diagnostic accuracy of the IIEF-5. The recommendation is to edit questions 1 and 5 when they are applied to populations with LPE.

Abstract
INTRODUCTION Some factors associated with the four premature ejaculation (PE) syndromes have been studied, but the association between International Prostate Symptom Score (IPSS) and the four PE syndromes has not been investigated. AIMS We performed this study to evaluate the association between IPSS and intravaginal ejaculatory latency time (IELT) in men with the four PE syndromes. METHODS From June 2012 to January 2014, a total of 690 men aged 40-59 years complaining of ejaculating prematurely and another 452 male healthy subjects of the same age without these complaints were included in this study. Men with the complaints of ejaculating prematurely were classified as one of the four PE syndromes: lifelong PE, acquired PE (APE), variable PE, and subjective PE. Each of them completed a detailed questionnaire including information on demographics, medical and sexual history (e.g., self-estimated IELT), IPSS, and International Index of Erectile Function-5. MAIN OUTCOME MEASURES Associations between IPSS and self-estimated IELT in middle-aged men with the four PE syndromes. RESULTS Men complaining of ejaculating prematurely reported higher IPSS (11.2 ± 6.0 vs. 5.5 ± 3.3 ) and shorter self-estimated IELT (2.1 ± 1.6 minutes vs. 4.8 ± 3.3) than men without complaints (P < 0.001 for each). By unilabiate analysis, self-estimated IELT in men with the four PE syndromes showed significant correlations with IPSS (P < 0.001 for all). After adjusting for age, self-estimated IELT was negatively associated with IPSS in men with PE complaints (adjusted r = -0.378, P < 0.001). Also, the association was stronger in men with APE (adjusted r = -0.502, P < 0.001). CONCLUSIONS Men complaining of ejaculating prematurely reported worse IPSS than men without these complaints. Self-estimated IELT was negatively associated with IPSS in men complaining of ejaculating prematurely, and the correlation was the strongest in men with APE.

Abstract
Introduction The International Society for Sexual Medicine (ISSM) Ad Hoc Committee for the Definition of Premature Ejaculation developed the first evidence-based definition for lifelong premature ejaculation (PE) in 2007 and concluded that there were insufficient published objective data at that time to develop a definition for acquired PE. Aim The aim of this article is to review and critique the current literature and develop a contemporary, evidence-based definition for acquired PE and/or a unified definition for both lifelong and acquired PE. Methods In April 2013, the ISSM convened a second Ad Hoc Committee for the Definition of Premature Ejaculation in Bangalore, India. The same evidence-based systematic approach to literature search, retrieval, and evaluation used by the original committee was adopted. Results The committee unanimously agreed that men with lifelong and acquired PE appear to share the dimensions of short ejaculatory latency, reduced or absent perceived ejaculatory control, and the presence of negative personal consequences. Men with acquired PE are older, have higher incidences of erectile dysfunction, comorbid disease, and cardiovascular risk factors, and have a longer intravaginal ejaculation latency time (IELT) as compared with men with lifelong PE. A self-estimated or stopwatch IELT of 3 minutes was identified as a valid IELT cut-off for diagnosing acquired PE. On this basis, the committee agreed on a unified definition of both acquired and lifelong PE as a male sexual dysfunction characterized by (i) ejaculation that always or nearly always occurs prior to or within about 1 minute of vaginal penetration from the first sexual experience (lifelong PE) or a clinically significant and bothersome reduction in latency time, often to about 3 minutes or less (acquired PE); (ii) the inability to delay ejaculation on all or nearly all vaginal penetrations; and (iii) negative personal consequences, such as distress, bother, frustration, and/or the avoidance of sexual intimacy. Conclusion The ISSM unified definition of lifelong and acquired PE represents the first evidence-based definition for these conditions. This definition will enable researchers to design methodologically rigorous studies to improve our understanding of acquired PE.

Abstract
INTRODUCTION Besides lifelong premature ejaculation (LPE) and acquired premature ejaculation (APE), Waldinger and Schweitzer proposed two addition PE syndromes (variable PE [VPE] and subjective PE [SPE]). AIM We assessed the associations between intravaginal ejaculatory latency time (IELT) and National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) in men with different PE syndromes. METHODS From September 2011 to September 2012, a total of 4,000 men were enrolled from the Anhui province of China. Subjects were required to complete a verbal questionnaire, including demographic information, medical and sexual history (e.g., IELT), and self-estimated scales (e.g., NIH-CPSI). MAIN OUTCOME MEASURES IELT; NIH-CPSI; the new classification of PE syndromes. RESULTS Of 3,016 of the men evaluated, 25.80% complained of PE. Distribution of the four PE syndromes among men with complaints of PE was as follows: LPE, 12.34%; APE, 18.77%; VPE, 44.09%; and SPE, 24.81%. Men with complaints of PE reported worse NIH-CPSI scores and lower IELT than men without complaints of PE (P < 0.001 for all). Moreover, total and subdomain scores of NIH-CPSI were higher in men with APE, and IELT was higher in men with SPE. IELT was negatively associated with NIH-CPSI scores in men with complaints of PE. Negative relationships between total and subdomain scores of NIH-CPSI and IELT were stronger in men with APE (total scores: adjusted r = -0.68, P < 0.001; pain symptoms: adjusted r = -0.70, P < 0.001; urinary symptoms: adjusted r = -0.67, P < 0.001; quality of life impact: adjusted r = -0.64, P < 0.001). CONCLUSION Men with complaints of PE reported worse NIH-CPSI scores than men without complaints of PE. Relationships between IELT and NIH-CPSI scores were strongest in men with APE.

Abstract
OBJECTIVE Premature ejaculation is one of the most common forms of male sexual dysfunction. Recent clinical and genetic evidence suggests that it can be classified into 4 subtypes, which may have distinct clinical profiles. Psychological factors, such as anxiety, may play a specific role in the acquired subtype. The objective of this study was to assess the association between psychological factors, particularly anxiety and marital disharmony, and the various subtypes of premature ejaculation. METHOD The case records of 28 men presenting with premature ejaculation to a clinic for psychosexual disorders in India between January 2012 and January 2013 were reviewed. The patients were classified into 4 subtypes (lifelong, acquired, natural variable, and premature-like ejaculatory dysfunction) and compared in terms of demographic and clinical profile. RESULTS Performance anxiety during intercourse was significantly associated with the acquired subtype of premature ejaculation (P = .011, Fisher exact test). Marital disharmony was equally common in the lifelong and acquired subtypes of premature ejaculation (P = not significant, Fisher exact test) and, in most cases, could be attributed to the distress caused by premature ejaculation itself. DISCUSSION Our results are consistent with existing literature that shows an association between anxiety and premature ejaculation, particularly the acquired subtype. Anxiety may play a causal or perpetuating role in these patients. If replicated, such a finding would have important therapeutic implications.

Abstract
In spite of its high prevalence and long history, the ambiguity regarding the definition, epidemiology and management of premature ejaculation continues. Topical anesthetic creams and daily or on-demand selective serotonin reuptake inhibitor (SSRI) treatment forms the basis of pharmacotherapy for premature ejaculation today, in spite of low adherence by patients. Psychotherapy may improve the outcomes when combined with these treatment modalities. Tramadol and phosphodiesterase type 5 inhibitors have a limited role in the management of premature ejaculation. Further research is required to develop better options for the treatment of this common sexual disorder.

Abstract
INTRODUCTION The premature ejaculation diagnostic tool (PEDT) was developed to standardize the diagnosis of PE and has been applied in many countries. However, a linguistic validation of the Chinese version of PEDT does not exist. AIMS This study aims to undertake the Chinese validation of the PEDT and to evaluate its association with self-estimated intravaginal ejaculatory latency time (IELT) and clinical expert diagnosis of PE. METHODS A Chinese version of PEDT was confirmed by andrologist and bilingual linguist. Participants were recruited among seven different communities of Shanghai from 2011 to 2012, and their information regarding self-reported PE, self-estimated IELT, expert diagnosis of PE, and PEDT scores were collected. MAIN OUTCOME MEASURES Validity of the PEDT and its association with clinical expert diagnosis of PE and self-estimated IELT were analyzed. RESULTS A total of 143 patients without PE (mean age 55.11 ± 7.65 years) and 100 men with PE (mean age 53.07 ± 8.08 years) were enrolled for validation. Of the patients in PE group, the number of men reporting self-estimated IELTs of ≤1, 1-2, and >2 minutes were 34 (34.0%), 22 (22.0%), and 44 (44.0%), respectively. The Cronbach's alpha score (α = 0.77) showed adequate internal consistency, and the test-retest correlation coefficients of each item (r ≥ 0.70, P < 0.001) indicated excellent stability over time. The frequency of agreement showed that there was excellent concordance between PEDT diagnosis and clinician diagnosis when the PEDT scores ≥11. An adequate correlation was found between total PEDT score and self-estimated IELT (ρ = -0.396, P < 0.001), and sensitivity and specificity analyses suggested a score of ≤8 indicated no time-defined PE (self-estimated IELT ≤1 minute). CONCLUSIONS The Chinese version of PEDT is valid in screening the presence of PE among Chinese men. The PEDT showed an adequate negative correlation with self-estimated IELT and an excellent concordance with clinician diagnosis of PE.

Abstract
INTRODUCTION In 2009, the International Society for Sexual Medicine (ISSM) convened a select panel of experts to develop an evidence-based set of guidelines for patients suffering from lifelong premature ejaculation (PE). That document reviewed definitions, etiology, impact on the patient and partner, assessment, and pharmacological, psychological, and combined treatments. It concluded by recognizing the continually evolving nature of clinical research and recommended a subsequent guideline review and revision every fourth year. Consistent with that recommendation, the ISSM organized a second multidisciplinary panel of experts in April 2013, which met for 2 days in Bangalore, India. This manuscript updates the previous guidelines and reports on the recommendations of the panel of experts. AIM The aim of this study was to develop clearly worded, practical, evidenced-based recommendations for the diagnosis and treatment of PE for family practice clinicians as well as sexual medicine experts. METHOD A comprehensive literature review was performed. RESULTS This article contains the report of the second ISSM PE Guidelines Committee. It offers a new unified definition of PE and updates the previous treatment recommendations. Brief assessment procedures are delineated, and validated diagnostic and treatment questionnaires are reviewed. Finally, the best practices treatment recommendations are presented to guide clinicians, both familiar and unfamiliar with PE, in facilitating treatment of their patients. CONCLUSION Development of guidelines is an evolutionary process that continually reviews data and incorporates the best new research. We expect that ongoing research will lead to a more complete understanding of the pathophysiology as well as new efficacious and safe treatments for this sexual dysfunction. We again recommend that these guidelines be reevaluated and updated by the ISSM in 4 years.
