The psychological burden of premature ejaculation

PURPOSE: Premature ejaculation is characterized by short ejaculatory latency, inability to control ejaculation and resultant overall decreased sexual satisfaction for the man and his partner. Diagnostic criteria typically include aspects of psychological well-being. To motivate and justify treatment for premature ejaculation a more comprehensive understanding of its impact on men, their partners and their overall relationship is needed. MATERIALS AND METHODS: In a community based, observational study of 1,587 men and their female partners clinicians diagnosed premature ejaculation using Diagnostic and Statistical Manual of Mental Disorders, 4th edition, text revision criteria. For purposes of this analysis this group was further restricted to subjects with a stopwatch measured intravaginal ejaculatory latency time of 2 minutes or less. Responses to the Premature Ejaculation Profile, Self-Esteem and Relationship questionnaire, Golombok-Rust Inventory of Sexual Satisfaction and Medical Outcomes Study SF-36 were compared between premature ejaculation and nonpremature ejaculation groups. Correlations between responses of men and partners were assessed for the Premature Ejaculation Profile and Golombok-Rust Inventory of Sexual Satisfaction. Correlations among patient reported measures enabled the assessment of independence of outcome variables. RESULTS AND CONCLUSIONS: Of 207 men who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition, text revision criteria 89 had an intravaginal ejaculatory latency time of 2 minutes or less. Lower levels of sexual functioning and satisfaction, and higher levels of personal distress and interpersonal difficulty were reported by men with premature ejaculation and their partners. In addition, men with premature ejaculation rated their overall quality of life lower than that of men without premature ejaculation. Consequently premature ejaculation has a significant psychological burden on men, their partners and the male/partner relationship.     

Premature ejaculation: results from a five-country European observational study

OBJECTIVES: To characterize premature ejaculation (PE) in five European countries using intravaginal ejaculatory latency time (IELT) and the Premature Ejaculation Profile (PEP). METHODS: This 8-wk, multicenter, observational study enrolled men >or=18 yr of age and their female partners. Clinicians diagnosed PE using the DSM-IV-TR criteria and at least moderate, subject-reported, ejaculation-related personal distress or interpersonal difficulty. The PEP was administered at baseline and weeks 4 and 8. Partners measured IELT; the average stopwatch-measured IELT for each 4-wk period was calculated and compared with the man's screening-estimated IELT. Relationships between individual PEP measures and IELT were assessed with path analysis. RESULTS: PE was diagnosed in 201 of 1115 men. Findings were similar to those in a similarly conducted US study. Mean IELT was lower in the PE versus the non-PE group (3.3 vs. 10.0min, respectively), but substantial overlap was observed. Men with PE and their partners reported significantly worse control over ejaculation, ejaculation-related personal distress, satisfaction with sexual intercourse, and ejaculation-related interpersonal difficulty than men without PE and their partners. Path analysis showed that perceived control over ejaculation had a significant effect on ejaculation-related personal distress and satisfaction with sexual intercourse; IELT had an effect on control over ejaculation, no direct effect on satisfaction with sexual intercourse, and a small direct effect on ejaculation-related personal distress. CONCLUSIONS: No major cultural differences existed between EU and US men with and without PE and their female partners. These results emphasize the importance of the PEP measures, especially perceived control over ejaculation, in characterizing PE.     

New approach to patients with premature ejaculation: Do social cognition and attachment profiles play a role in premature ejaculation?

Premature ejaculation is the most prevalent male sexual dysfunction and causes significant individual and relational distress in subjects. This study aimed to investigate the underlying psychopathologies of premature ejaculation using theory of mind, empathy and attachment parameters and included 91 participants: 46 with lifelong premature ejaculation and 45 without any ejaculatory complaints. Arabic index of premature ejaculation and stopwatch intravaginal ejaculatory latency times were recorded from all subjects in order to evaluate ejaculatory function. We used reading mind in the eyes, empathy quotient and experiences in close relationships-revised tasks to evaluate social cognitive and attachment profiles of the participants. We compared differences between groups in terms of task performances and symptom severity. Premature ejaculation patients showed significantly low levels of theory of mind abilities as well as empathic skills compared to controls. Although groups did not differ significantly in means of attachment avoidance parameters, premature ejaculation patients had significantly higher levels of attachment anxiety parameters. There was no correlation between symptom severity and social cognition and attachment scores in premature ejaculation patients. These results suggest that patients with premature ejaculations may suffer from significant social cognitive deficits and have anxious but not avoidant pattern of attachment. These results may implicate insights in terms of pharmacological and psychotherapeutic treatments of premature ejaculation.     

The etiology and management of premature ejaculation

Premature ejaculation (PE) is a common male sexual disorder. Normative data suggest that men with an intravaginal ejaculatory latency time of less than 1 min have 'definite' premature ejaculation, while men with intravaginal ejaculatory latency times of between 1 and 1.5 min have 'probable' premature ejaculation. Although there is insufficient empirical evidence to identify the etiology of PE, there is correlational evidence to suggest that men with PE have high levels of sexual anxiety and altered sensitivity of central 5-hydroxytryptamine receptors. Pharmacological modulation of the ejaculatory threshold using daily or on-demand selective serotonin reuptake inhibitors offers patients a high likelihood of achieving improved ejaculatory control within a few days of initiating treatment, leads to improvements in sexual desire and other sexual domains, and is well tolerated.     

Premature ejaculation: the current literature

PURPOSE OF REVIEW: The recent increase in research with regard to premature ejaculation has led to a significant number of new papers looking at the diagnosis, definition, aetiology and management of this condition. RECENT FINDINGS: The intravaginal ejaculatory latency time remains the primary measure of ejaculatory time although increasing bother and distress require assessment and establishment of quantifiable measures. Biological and psychogenic causes contribute to a multifactorial model of premature ejaculation with some neurobiological vulnerability. The principal treatments are selective serotonin reuptake inhibitors and behavioural cognitive interventions. New treatment interventions are under investigation. SUMMARY: A number of guideline papers confirm that a primary sexual history and a multimodel treatment approach provide the best approach to patients with this common condition.     

早泄诊断和治疗

早泄(premature ejaculation,PE)是临床上最常见的主诉之一,其共同特征为:射精潜伏期缩短、延迟或控制射精的能力下降、并引起患者痛苦/烦恼。目前尚无一致公认的PE定义。不同定义之间争论的焦点是如何设定射精潜伏期(intravaginal ejaculatory latency time,IELT)。新的分类方法将PE分为:原发性、继发性、自然变异性和早泄样射精障碍。不同类型PE发生的病理生理和病因学不同,决定了治疗方案的差异。     

Long-term effects of glans penis augmentation using injectable hyaluronic acid gel for premature ejaculation

The authors created the glans penis augmentation by injectable hyaluronic acid gel and reported the 6-month result for premature ejaculation. In a total of 38 patients, long-term effects of 5 years were compared to those of 6 months in terms of residual volume of implants and efficacy on premature ejaculation. Maximal glandular circumference measured by tapeline significantly decreased by 15% (P<0.05) but mean patient's visual estimation (Gr 0-Gr 4) did not decrease (3.60 vs 3.56, P>0.05). Compared to 6-month follow-up, intravaginal ejaculatory latency time and vibratory threshold decreased at 5 years (P<0.05), but still well increased considering those of preaugmentation. Hence, 76% of patients and 63% of partners were still satisfied. There was no serious adverse reaction. In the 5-year long-term follow-up of glans penis augmentation by filler, the implants were well maintained and effective for glans penis hypersensitivity in premature ejaculation patients.     

Der vorzeitige Samenerguss (Ejaculatio praecox)

With prevalence rates of 20%–25% premature ejaculation (PE) represents the most frequent sexual dysfunction in men. Whereas genetically determined changes in the serotonin receptor-/transporter mechanism seem to be responsible for lifelong PE, acquired PE is often associated with other conditioning diseases such as erectile dysfunction, prostatitis or thyroid dysfunctions. Typical features of PE are a short intravaginal ejaculatory latency time (IELT) <1–2 min, lack of control over ejaculation, personal distress and partner problems. Treatment of PE subdivides into sexual therapy as well as drug therapy. Among the medications considered for PE, oral therapy with selective serotonin re-uptake inhibitors (SSRI), Dapoxetine (the first officially approved medication for PE) and topical therapy with lidocaine/prilocaine-containing medications are given priority.     

Safety and efficacy of traditional Chinese medicine,Qiaoshao formula,combined with dapoxetine in the treatment of premature ejaculation: An open-label,real-life,retrospective multicentre study in Chinese men

To evaluate the safety and efficacy of Chinese medicine, Qiaoshao formula combined with dapoxetine was used for the treatment of premature ejaculation in a real-life setting. Nine hundred and five males diagnosed with premature ejaculation were reviewed in this retrospective cohort study. We divided the patients into two groups: dapoxetine alone and Qiaoshao formula combined with dapoxetine according to actual interventions provided to patients in clinics. The perceived intravaginal ejaculation latency time and the premature ejaculation profile measures markedly improved in both groups. However, in men with severe premature ejaculation (baseline perceived intravaginal ejaculation latency time <1 min) and those with baseline age ≤30 years, the perceived intravaginal ejaculation latency time was slightly but significantly longer with combined therapy than with dapoxetine alone (p < .05). Therefore, combined therapy involving the Qiaoshao formula and dapoxetine proved to safe as well as effective for treating premature ejaculation while prolonging the perceived intravaginal ejaculation latency time, which significantly improved the overall satisfaction of the patient and likely that of the couple.     

Venlafaxine extended release for the treatment of patients with premature ejaculation: a pilot, single-blind, placebo-controlled, fixed-dose crossover study on short-term administration of an antidepressant drug

In this study, we aimed at evaluating the efficacy and safety of venlafaxine extended release 75 mg, a serotonin and noradrenaline reuptake inhibitor, in the treatment of patients with premature ejaculation. Thirty-one patients with intravaginal ejaculation latency of less than 2 min received venlafaxine XR (75 mg/day) or placebo during a 2-week period for each agent with a washout period of 1 week between agents. Efficacy was assessed for each agent with changes in ejaculation latency measured with a stopwatch and sexual satisfaction scores of patients and partners. Side-effects, pre- and post-treatment levels of biochemical and spermiogram parameters, follicle-stimulating hormone (FSH), luteinizing hormone (LH), prolactin and total testosterone were recorded for each agent. Statistical analysis was performed on 21 patients. After 2 weeks of treatment with placebo and venlafaxine, ejaculation latency time was significantly increased from 60.1 +/- 39.1 to 126.9 +/- 98.3 sec and to 178.1 +/- 122.8 sec, respectively (p < 0.0001 for each one). However, the difference between the two agents was insignificant (p = 0.144). Venlafaxine and placebo increased sexual satisfaction scores of both patients and partners similarly, no statistically significant difference was found between them in this respect. The incidence of side-effects with venlafaxine was indifferent than that of placebo (p > 0.1) except nausea (p = 0.035). Both agents did not change the blood and spermiogram parameters significantly, except FSH increases. Short-term use of venlafaxine XR 75 mg has only a placebo effect on ejaculation latency and sexual satisfaction scores, therefore, is not appropriate for the patients with premature ejaculation. Further dose-time studies are required to draw final conclusions on the inefficacy of this drug in premature ejaculation.     

A pilot study to evaluate the effects of vardenafil on sexual distress in men with obesity

There are no interventional studies on the impact of sexual distress (SD) in men with obesity. We investigated the effects of vardenafil (VAR) on SD in middle-aged (mean age 49 ± 8), healthy, obese men in the absence of premature ejaculation, ED or hypogonadism. After a 4-week run-in period, 20 men with high body mass index (BMI=40 ± 8) and SD at the Sexual Distress Esteem Questionnaire-Male (mean score 65 ± 20 AU) were randomized to receive either VAR 10 mg on demand (N=10) or matched-placebo (PLB, N=10). Primary endpoints were variations from baseline in the intravaginal ejaculatory latency time (IELT) measured by the stopwatch technique; secondary endpoints were variations from baseline in Self-Esteem and Relationship (SEAR) and Male Sexual Health Questionnaire-Ejaculatory domain (MSHQ-EjD) scores. VAR significantly improved IELT (P<0.0001), as well as SEAR (P<0.001) and MSHQ-EjD (P<0.005) scores, whereas no changes were observed after PLB. Interestingly, an inverse relationship between BMI and IELT was found in all the men studied (r(2)=0.37, P<0.001). SD in healthy obese men seems to be correlated mainly with inadequate ejaculatory control, especially in men with higher BMI. Our preliminary results suggest that treatment with VAR may improve ejaculatory control, thus ameliorating self-esteem and sexual performance in men with obesity.     

Animal models of premature and retarded ejaculation

Most of our current understanding of the neurobiology of sexual behavior and ejaculatory function has been derived from animal studies using rats with normal sexual behaviour. However, none of these proposed models adequately represents human ejaculatory disorders. Based on the ejaculation distribution theory, which postulates that the intravaginal ejaculation latency time in men is represented by a biological continuum, we have developed an animal model for the research of premature and delayed ejaculation. In this model, a large number of male Wistar rats are investigated during 4–6 weekly sexual behavioural tests. Based on the number of ejaculations during 30 min tests, rapid and sluggish ejaculating rats are distinguished, each representing approximately 10% at both ends of a Gaussian distribution. Together with other parameters, such as ejaculation latency time, these rats at either side of the spectrum resemble men with premature and delayed ejaculation, respectively. Comparable to the human situation, in a normal population of rats, endophenotypes exist with regard to basal sexual (ejaculatory) performance.     

Evolving therapeutic strategies for premature ejaculation: The search for on-demand treatment �C topical versus systemic

Premature ejaculation (PE) is a common sexual dysfunction affecting 20% to 30% of men worldwide. Definitions of PE vary, but it is typically characterized by short intravaginal ejaculatory latency time (IELT) with concomitant sexual dissatisfaction and distress. PE may be lifelong or acquired, but its etiology remains unclear. Treatment of PE typically involves pharmacotherapy, particularly when lifelong. Although there are numerous reports on the off-label use of selective serotonin reuptake inhibitors (SSRIs) and other compounds, only 2 treatments have been evaluated in randomized controlled phase 3 clinical trials: PSD502 and dapoxetine (SSRI). Both significantly improved IELT and patient-reported outcome domains of ejaculatory control, sexual satisfaction, and distress as measured by the index of premature ejaculation (IPE), compared with placebo. They constitute the focus of this review. Evidence demonstrated that PSD502, dapoxetine and other SSRIs all significantly improve the symptoms of PE. Systemic use of SSRIs presents risks associated with the known pharmacology of this class. PSD502 allows for topical on-demand treatment applied applied immediately before intercourse, and is not associated with systemic adverse events.     

Comparison of the efficacy and safety of 90 mg versus 20 mg fluoxetine in the treatment of premature ejaculation

PURPOSE: We compare the efficacy and side effects of 90 mg fluoxetine once weekly versus 20 mg fluoxetine as single oral therapy for patients complaining of premature ejaculation without evident organic causes. MATERIALS AND METHODS: The study comprised 80 patients with a mean age of 36 years with premature ejaculation who presented to the urology clinic of 3 hospitals in Barcelona. Pretreatment evaluation included history and physical examination, International Index of Erectile Function (IIEF), Meares-Stamey test and ejaculatory latency time evaluation. The patients were randomized into treatment groups receiving 1 capsule of 90 mg fluoxetine a week (group 1) and 1 capsule of 20 mg fluoxetine a day (group 2) for 3 months. The 4-month followup included: ejaculatory latency time measurement, IIEF and partner sexual satisfaction. RESULTS: Mean pretreatment ejaculatory latency times for groups 1 and 2 were 0.48 minute (range 0 to 2.10) and 0.50 minute (0 to 2.04), respectively. After 3 months of treatment of weekly and daily administration of fluoxetine mean ejaculatory latency time was 3.57 and 3.37 minutes, respectively (p >0.01). Partner sexual satisfaction and IIEF rate were greater with 90 mg fluoxetine but no statistical difference was found. Nausea, insomnia and headache were reported side effects but no significant difference was noted between 90 and 20 mg fluoxetine. CONCLUSIONS: In men with premature ejaculation 90 mg fluoxetine weekly may be regarded as an effective and safe treatment.     

Global perspectives on the three criteria for premature ejaculation: An observational study of ejaculatory latency,ejaculatory control and bother/distress

Criteria for premature ejaculation (PE) were established using Western-based samples, yet these criteria are applied worldwide for its diagnosis. This study (a) determined whether men from various world regions differ/agree on their views of ejaculation latency (ELT) and their perceptions of ejaculatory control and bother/distress, the three criteria for PE, and (b) compared PE and non-PE men across worldwide regions on these measures. 1,065 participants were recruited via social media to respond to a survey about men's typical, ideal and PE ELTs, about their own ELT, and about perceptions of ejaculatory control and bother/distress related to PE. Responses from men from four worldwide regions were compared to a reference group of North American/European men, and PE men were compared with non-PE men across three world regions. Results showed that most world region groups showed similarity in ELT estimations. The Sub-Saharan group focused more heavily on the importance of ejaculatory control. Both ELT and ejaculatory control differed between PE and non-PE groups in all regions assessed. In conclusion, perceived ELTs and ejaculatory control show substantial consistency across world regions despite geo-cultural variations and traditions. Such findings argue for the universality of the concepts of ELT, control and bother/distress related to PE.     

The Impact of Premature Ejaculation on Partners and Relationships

ObjectivesPremature ejaculation (PE) is a common condition in adult males that remains underdiagnosed and undertreated, partially because the sensitive nature of the topic discourages open discussions between affected males, their partners, and physicians. In addition to reduced sexual satisfaction, PE can have emotional consequences such as distress and dissatisfaction with the overall relationship, not only for the males but also their partners, the perspectives of whom have not been widely studied.MethodsAn online survey of female partners of men with PE was conducted to determine how the condition affects women and their relationships.ResultsThe results revealed that the relatively short intravaginal ejaculatory latency time (IELT) associated with PE causes emotional distress for the female partners (N = 115). The majority of female partners wanted to experience a prolonged IELT and considered that this would enhance both their sexual and overall relationship with their partner.ConclusionsIncreased awareness of the nature of the emotional and relationship ramifications of PE on men and their sexual partners should enhance the development of treatment options beyond pharmacotherapy alone.

Towards evidence-based drug treatment research on premature ejaculation: a critical evaluation of methodology

In the last decade, an increasing number of drug studies on premature ejaculation have been published. The methodology used in these studies differed widely. In this review, it is therefore questioned as to how far the differences in methodology could have influenced clinical outcomes. The aim of the present review was to compare the different methodologies that were used in drug studies on premature ejaculation. The majority of these studies were conducted between 1973 and 2003 and were strikingly different in study design and in the quantification of clinical outcomes. It appeared that in some of these studies, placebo and active drug effects were neglected due to an erroneous methodology. The few studies that were using stopwatch assessment at each intercourse at baseline and during treatment and in which the intravaginal ejaculation latency time (IELT) was included appeared to be comparable in their results. The use of a well-defined definition of premature ejaculation, for example, an IELT of less than 1 min revealed reproducible results. Finally, the retrospective use of a questionnaire or a subjective report on ejaculation time induced higher effects with regard to placebo effects and an underestimation of active drug effects. In conclusion, for drug treatment research of premature ejaculation it is recommended to use a randomized double-blind prospective design, the use of the IELT, the use of a stopwatch at each coitus both during a baseline period and during drug treatment and a definition of premature ejaculation as an ejaculation that occurs within 1 min after vaginal penetration.     

Application of micronised acellular dermal matrix for primary premature ejaculation: A preliminary study

This study aimed to explore the efficacy of injection of micronised acellular dermal matrix (MADM) particles for treating primary premature ejaculation. This study was a prospective single-arm clinical trial. Thirty patients who met the surgical indications were enrolled. MADM particles, mixed in platelet-rich plasma, were injected into Buck's fascia to spread over the dorsal penile nerve, suppress the influx of nerve impulses and, thus, reduce penis sensitivity. We evaluated the changes according to intravaginal ejaculation latency time using a stopwatch and a premature ejaculation diagnostic tool. Meanwhile, we also recorded sexual partner satisfaction and adverse events. All patients recovered well after surgery with no complications such as infections or allergies. The mean intravaginal ejaculation latency time before surgery was 0.72 ± 0.28 min, compared with 2.41 ± 0.54 min, 2.64 ± 0.41 min, 2.79 ± 0.25 min and 2.89 ± 0.35 min at, respectively, 4, 8, 16 and 20 weeks after surgery. The premature ejaculation diagnostic values and sexual partner satisfaction had significantly improved after treatment. Injection of MADM particles is an effective, safe and simple method for treating premature ejaculation.     

Silodosin and its potential for treating premature ejaculation: A preliminary report

Premature ejaculation is a common sexual problem, as is erectile dysfunction. We evaluated silodosin, a highly selective α1A‐adrenoceptor antagonist, as a new treatment option for premature ejaculation. α1‐Adrenoceptor antagonists are widely used for lower urinary tract symptoms, and clinical studies on silodosin have shown excellent clinical efficacy for lower urinary tract symptoms. However, compared with other α1‐adrenoceptor antagonists, silodosin appeared to suppress ejaculation in a relatively higher percent of trial participants. This suppression of ejaculation by silodosin suggested its potential for treating premature ejaculation. Consequently, we evaluated the feasibility of off‐label silodosin as a new treatment option for premature ejaculation. Eight patients suffering premature ejaculation were treated with silodosin. Silodosin (4 mg) was given 2 h before sexual intercourse. Intravaginal ejaculatory latency time, premature ejaculation profile item, clinical global impression change in premature ejaculation and systemic adverse events were recorded. Intravaginal ejaculatory latency time was significantly prolonged (from 3.4 min to 10.1 min, P = 0.003). All patients answered better (much better) or slightly better for their own premature ejaculation problem compared with pretreatment condition in the clinical global impression change. Premature ejaculation profile also significantly improved. Two (25%), three (37.5%) and seven patients (87.5%) experienced anejaculation, reduced semen volume and discomfort during orgasm, respectively. However, these problems were not of major concern for the participants. No systemic adverse effects were reported. The current results support the possible use of silodosin as a new treatment option for premature ejaculation, and suggest that a placebo controlled study assessing its clinical usefulness would be worthwhile.
