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 Unfortunately, portions of that narrative are outdated and do not reflect more recent conceptualizations or empirical findings regarding this disorder.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.

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

[PMID: 37926381 DOI: 10.1016/j.urology.2023.09.055] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Revised: 08/30/2023] [Accepted: 09/08/2023] [Indexed: 11/07/2023]
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.

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.

Abstract
Background Premature ejaculation (PE) is one of the most common male sexual dysfunctions with prominent psychological consequences. Type D personality (TDP) is also associated with multiple psychological disorders, such as depression and anxiety. However, the correlation between PE and TDP remains unknown. Aim The study sought to investigate the relationships between depressive symptoms, TDP, and PE. Methods Adult males in Taiwan who were 20 to 40 years of age and who had sexual intercourse in the past 6 months were recruited to complete online questionnaires composed of general demographics, the Premature Ejaculation Diagnostic Tool (PEDT), 5-item International Index of Erectile Function (IIEF-5), Type D Scale-14, and Depression and Somatic Symptom Scale (DSSS). Chi-square test and independent Student's t test were used to compare the parameters between the TDP and non-TDP groups. Univariate and multivariate logistic regression analyses were conducted to evaluate factors related to PE. Outcomes Outcomes were the prevalence of PE and TDP in young Taiwanese men, the associations between depressive symptoms and PE and TDP, and the predictive factors of PE. Results In total, 2558 men with a mean age of 31.3 ± 5.3 years were included in the present study. Among them, 315 (12.3%) and 767 (30.1%) participants were classified as having PE and moderate-to-severe erectile dysfunction (ED), respectively. In total, 1249 (48.8%) participants met the criteria for TDP. The PEDT, IIEF-5, and DSSS, including the total scores and depression and somatic subscales, were significantly higher in men with TDP (all P < .001). PE prevalence was significantly greater in men with TDP than in those without TDP (16.2% vs 8.6%; P < .001). Most parameters, including age, moderate-to-severe ED, the Type D Scale-14 subscales, and the DSSS somatic and depressive subscales, were significantly associated with PE in the univariate analysis. Only the depressive subscale of the DSSS and moderate-to-severe ED (IIEF-5 ≤16) were the independent predictors of PE in the multivariate analysis. Clinical Implications The results suggest that it is important to consider the psychological effects of PE in young men, and the study has provided a biopsychosocial aspect to manage patients with PE. Strengths and Limitations This is the first study to evaluate the association between PE, TDP, and depression in a large population of young adult males. However, the cross-sectional design may have limited the investigation of causality, and selection bias may be present. Conclusion Men with TDP tended to have higher PEDT scores and a prevalence of PE and ED. Moderate-to-severe ED and depressive symptoms are the independent predictive factors of PE.

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 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.

J Sex Med 2021; 18:1677-1689.

Abstract
BACKGROUND Premature ejaculation is the most common sexual dysfunction in young men, and it often leads to reduced relationship satisfaction and quality of life. AIM To determine the role of central and peripheral α2-adrenoceptors in the control of ejaculation and sexual incentive motivation in rats. METHODS Sexual incentive motivation was studied in a large arena in which a male subject could choose between approaching and remaining close to a sexually receptive female or another male. Sexual behavior was studied in standard observation cages in which a male was allowed to freely interact with a receptive female for 30 minutes. Two highly selective agonists at the α2-adrenoceptors, tasipimidine and fadolmidine, were administered before the tests. Low peripheral doses of fadolmidine have been reported to have effects mainly outside of the central nervous system, whereas at large doses also the central effects are evident. OUTCOMES The time spent close to the receptive female in relation to the time spent with the male and measures of ambulatory activity were obtained from the test for sexual incentive motivation, while the habitual parameters of sexual behavior were recorded with the copulation test. RESULTS Tasipimidine prolonged ejaculation latency and the interintromission interval at the dose of 200 µg/kg when data from fast-ejaculating rats were used. No other sexual parameter was modified. A dose of 100 µg/kg was ineffective. There was no consistent effect on sexual incentive motivation, although modest sedation was observed. Fadolmidine, a drug that does not easily penetrate the blood-brain barrier, had no effect on sexual incentive motivation at any of the doses used (3, 30, and 100 µg/kg). The largest dose had clear sedative effects. The lower doses had no systematic effect on sexual behavior, not even when only fast or very fast ejaculating males were analyzed. CLINICAL TRANSLATION The findings are relevant to the search for treatments for premature ejaculation that are specific enough to selectively delay ejaculation. STRENGTHS & LIMITATIONS The procedures used here are standard in the field and yield the most reliable data. Whether the effects observed in male rats are directly transferrable to men can only be determined through clinical studies. CONCLUSION The observation that drugs acting at central but not peripheral α2-adrenoceptors prolong ejaculation latency without affecting any other parameter of sexual behavior or sexual incentive motivation suggests that this kind of drug may be suitable for treating premature ejaculation.

Phosphodiesterase Type 5 Inhibitors and Risk of Skin Cancers in Men: A Meta-Analysis and Trial Sequential Analysis Involving 7,479,852 Subjects. World J Mens Health 2020; 39:683-696. [PMID: 33151043 PMCID: PMC8443994 DOI: 10.5534/wjmh.200082] [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: 04/28/2020] [Revised: 06/29/2020] [Accepted: 08/02/2020] [Indexed: 01/11/2023] Open
Abstract
Purpose We conducted a systematic review and meta-analysis to quantify the association between phosphodiesterase type 5 inhibitors (PDE5Is) use and skin cancers and we also examined whether down-expression of the PDE5A gene was related to worse prognosis for malignant melanoma (MM) patients. Materials and Methods The PubMed, Cochrane Library, Web of Science, EMBASE, and ClinicalTrails.gov databases were searched. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the association between PDE5Is use and risk of skin cancers. Cumulative meta-analysis and trial sequential analysis (TSA) were also conducted. Survival outcomes were analyzed online. Results After pooling all 8 eligible studies comprising 7,479,852 subjects, we found that PDE5Is use was significantly associated with slightly increased risk of developing MM (OR: 1.13, 95% CI: 1.05 to 1.21, I2=67.1%), basal cell carcinoma (OR: 1.16, 95% CI: 1.13 to 1.19, I2=49.6%), and squamous cell carcinoma (OR: 1.07, 95% CI: 1.01 to 1.13, I2=0.0%). Totally, PDE5Is increased the risk of developing skin cancers (OR: 1.13, 95% CI: 1.09 to 1.17, I2=70.8%). TSA results showed that the sample size was enough to reach a positive conclusion. Conclusions The use of PDE5Is may be slightly associated with increased risk of developing skin cancers. There should be a balance between drug benefits and potential safety issues. However, the pooled results should be considered tentative until confounding factors such as sun exposure and lifestyle are well-controlled in further studies.

Andrologia 2020; 52:e13787.

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.

Characteristics of men who are bothered by rapid ejaculation: results from clinical intake surveys. Int J Impot Res 2020; 33:369-375. [PMID: 32332929 DOI: 10.1038/s41443-020-0277-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2019] [Revised: 03/11/2020] [Accepted: 03/31/2020] [Indexed: 02/08/2023]
Abstract
The objective of this study is to identify factors associated with bother with rapid ejaculation in a cohort of men presenting to a sexual dysfunction clinic, independent of a diagnosis of PE. A prospective institutional database has been maintained on patients completing an 89-item intake questionnaire querying various areas of sexual dysfunction. Regarding ejaculatory dysfunction, patients are asked "Do you feel bothered, annoyed, and/or frustrated by ejaculating too quickly?" Statistical modeling was performed to identify associations. A total of 1359 men completed the intake survey, and 694 responded to the question on bother with rapid ejaculation. Overall, 42.9% (298/694) of respondents reported bother with rapid ejaculation. Men reporting bother were more likely to report lower intravaginal ejaculatory latency (IELT) time (4.2 vs 12.2 min, p < 0.0001), problems with depression (32% vs 21%, p = 0.001), negative impact on relationship (73% vs 51%, p < 0.0001), and negative impact on partner's sexual satisfaction (26% vs 15%, p < 0.001). These results highlight the importance of asking all men presenting with sexual health concerns about their bother with rapid ejaculation for complete assessment of sexual and mental wellbeing.
