Reexamining the Definitions of PE and DE

Similarities and differences between men with self-reported lifelong and acquired difficulty reaching ejaculation

Men with delayed ejaculation are often categorized into lifelong and acquired subtypes, yet little is known about similarities and differences between these groups. In this study, we examined whether delayed ejaculation subtypes differed on various demographic, diagnostic, relationship, and sexual activity/satisfaction variables. We drew 140 men reporting moderately-severe to severe difficulty reaching ejaculation during partnered sex (occurring during ≥75% of sexual events) from a convenience sample of over 3000 respondents obtained through an opt-in, multinational, online survey. Respondents were further classified as having lifelong or acquired delayed ejaculation based on self-report. A series of alpha-adjusted analyses of covariance were then made between subtypes on subsets of variables. In addition, the extent to which two potential confounding variables, age and erectile function, might have been responsible for subtype differences was explored. Results indicated that compared with men with acquired delayed ejaculation, men with lifelong delayed ejaculation were younger (28.6 vs 44.7 years, η2p = 0.30, P < 0.001), reported greater delayed ejaculation symptomology (4.31 vs 3.98, P < 0.01, η2p = 0.02), were less likely to attribute their problem to a medical issue or medication (1.7% vs 12.2%, P < 0.05), and more likely to masturbate for anxiety/distress reduction than for pleasure. In contrast, delayed ejaculation subtype differences related to masturbation frequency, pornography use during masturbation, and condom use disappeared when age and erectile functioning differences were statistically controlled. Overall, lifelong and acquired delayed ejaculation subtypes showed more similarities than differences. Findings worthy of clinical note were the lower level of endorsement of medical issues/medication by the lifelong subtype, their higher level of delayed ejaculation symptomology, and-despite a high level of anxiety/distress reported by both groups-their particular vulnerability to anxiety/distress as indicated by their strong motive to masturbate for anxiety/distress reduction (44.3% vs 19.6%, P < 0.05). Other differences between delayed ejaculation subtypes were better explained by group differences in age and erectile function than by subtype membership per se.

Recommendations for the diagnosis and evaluation of premature ejaculation

OBJECTIVES

The Association Interdisciplinaire Post-Universitaire de Sexologie (AIUS) has brought together a panel of experts to draw up French recommendations for the management of premature ejaculation. This article presents the recommendations for the diagnosis and evaluation of premature ejaculation.

METHODS

Systematic review of the literature between 01/1995 and 02/2022. Using the method of recommendations for clinical practice (RPC).

RESULTS

We recommend using the SIAMS definition for everyday clinical practice. PE is defined as: (i) a persistent and recurrent subjective perception of loss of control (management) of the ejaculatory mechanism in the presence of appropriate erotic stimuli; (ii) subjective, PE-related distress induced in the patient and sexual dissatisfaction or PE-related anorgamy in the partner; (iii) a short intravaginal ejaculatory latency time, whether subjectively perceived by the patient and the partner or objectively measured as less than 180seconds (generally). We suggest that the same definition be applied to practices other than vaginal penetration, such as masturbation, oral or anal intercourse, as well as to non-heterosexual contexts. We suggest using information reported by the patient, possibly supplemented by assessment tests/questionnaires (IPE, PEP, PEDT). We recommend investigating the presence of other sexual dysfunctions, in particular erectile dysfunction (ED), as well as any sexual dysfunctions of partners. We recommend taking a medical and psychosexological history, and carrying out a targeted physical examination in patients complaining of PE.

CONCLUSION

These recommendations should help to improve the management of PE.

Self-reported reasons for having difficulty reaching orgasm in men with diverse etiologies

Background

Difficulty reaching orgasm/ejaculation during partnered sex, a primary characteristic of delayed or absent ejaculation, affects about 5% to 10% of men, but the reasons underlying this problem are poorly understood.

Aim

The study sought to gain insight into possible etiologies of delayed ejaculation by assessing men's self-perceptions as to why they experience difficulty reaching orgasm.

Methods

We drew 351 men reporting moderately severe to severe difficulty reaching orgasm during partnered sex from a sample of over 3000 respondents obtained through an online survey. As part of the 55-item survey, participants responded to 2 questions asking about their self-perceived reasons for having difficulty reaching orgasm and selected from a list of 14 options derived from the research literature, a series of men's focus groups, and expert opinion. The first question allowed respondents to select all the reasons that they felt contributed to the problem, the second to select only the most important reason. In addition, both men with and without comorbid erectile dysfunction were investigated and compared.

Outcomes

Hierarchical ordering of men's self-pereceived reasons for having difficulty reaching orgasm, including typal reasons established through principal component analysis.

Results

The major reasons for difficulty were related to anxiety/distress and lack of adequate stimulation, with relationship and other factors endorsed with lower frequency. Further exploration using principal components analysis identified 5 typal reasons, in descending order of frequency: anxiety/distress (41%), inadequate stimulation (23%), low arousal (18%), medical issues (9%), and partner issues (8%). Few differences emerged between men with and without comorbid ED other than ones related to erectile problems, such as higher level of endorsement of medical issues. Typal reasons showed correlations, albeit mostly weak, with a number of covariates, including sexual relationship satisfaction, frequency of partnered sex, and frequency of masturbation.

Clinical Implications

Until supplemental medical treatments for delayed ejaculation are developed and approved, a number of men's purported reasons for difficult or absent ejaculation/orgasm-anxiety/distress, inadequate stimulation, low arousal, relationship issues-fall into areas that can be addressed in couples counseling by a trained sex therapist.

Strengths and Limitations

This study is unique in scope and robust in sample size. Drawbacks include those associated with online surveys, including possible bias in sample selection, limitation to Western-based samples, and the lack of differentiation between men with lifelong and acquired difficulty.

Conclusion

Men who have difficulty reaching ejaculation/orgasm identify putative reasons for their problem, ranging from anxiety/stress, inadequate stimulation, and low arousal to partner issues and medical reasons.

Characteristics of men who report symptoms of delayed ejaculation: providing support for empirically derived diagnostic criteria

BACKGROUND

Little is known regarding the demographic, sexual, and relationship characteristics of men with symptoms of delayed ejaculation (DE).

AIM

To identify differences between men with and without DE symptomology to validate face-valid diagnostic criteria and to identify various functional correlates of DE.

METHODS

A total of 2679 men meeting inclusion criteria were partitioned into groups with and without DE symptomology on the basis of their self-reported "difficulty reaching ejaculation/orgasm during partnered sex." Men were then compared on a broad array of demographic and relationship variables, as well as sexual response variables assessed during partnered sex and masturbation.

OUTCOMES

Outcomes included the identified differences between men with and without DE symptomology.

RESULTS

Men with DE-whether having comorbid erectile dysfunction or not-differed from men without DE on 5 face-valid variables related to previously proposed diagnostic criteria for DE, including ones related to ejaculation latency (P < .001); self-efficacy related to reaching ejaculation, as assessed by the percentage of episodes reaching ejaculation during partnered sex (P < .001); and negative consequences of the impairment, including "bother/distress" and (lack of) "orgasmic pleasure/sexual satisfaction" (P < .001). All such differences were associated with medium to large effect sizes. In addition, men showed differences on a number of functional correlates of DE, including anxiety, relationship satisfaction, frequency of partnered sex and masturbation, and level of symptomology during partnered sex vs masturbation (P < .001).

CLINICAL IMPLICATIONS

Face-valid criteria for the diagnosis of DE were statistically verified, and functional correlates of DE relevant to guiding and focusing treatment were identified.

STRENGTHS AND LIMITATIONS

In this first comprehensive analysis of its kind, we have demonstrated widespread differences on sexual and relationship variables relevant to the diagnosis of DE and to its functional correlates between men with and without DE symptomology during partnered sex. Limitations include participant recruitment through social media, which likely biased the sample; the use of estimated rather than clocked ejaculation latencies; and the fact that differences between men with acquired and lifelong DE were not investigated.

CONCLUSION

This well-powered multinational study provides strong empirical support for several face-valid measures for the diagnosis of DE, with a number of explanatory and control covariates that may help shed light on the lived experiences of men with DE and suggest focus areas for treatment. Whether or not the DE men had comorbid erectile dysfunction had little impact on the differences with men having normal ejaculatory functioning.

Understanding and treating ejaculatory dysfunction in men with diabetes mellitus

Diabetes mellitus is a rapidly rising metabolic disorder with important systemic complications. Global figures have demonstrated the prevalence of diabetes mellitus has almost quadrupled from 108 million in 1980 to 422 million in 2014, with a current prevalence of over 525 million. Of the male sexual dysfunction resulting from diabetes mellitus, significant focus is afforded to erectile dysfunction. Nevertheless, ejaculatory dysfunction constitutes important sexual sequelae in diabetic men, with up to 35%-50% of men with diabetes mellitus suffering from ejaculatory dysfunction. Despite this, aspects of its pathophysiology and treatment are less well understood than erectile dysfunction. The main disorders of ejaculation include premature ejaculation, delayed ejaculation, anejaculation and retrograde ejaculation. Although ejaculatory dysfunction in diabetes mellitus can have complex multifactorial aetiology, understanding its pathophysiological mechanisms has facilitated the development of therapies in the management of ejaculatory dysfunction. Most of our understanding of its pathophysiology is derived from diabetic animal models; however, observational studies in humans have also provided useful information in elucidating important associative factors potentially contributing to ejaculatory dysfunction in diabetic men. These have provided the potential for more tailored treatment regimens in patients depending on the ejaculatory disorder, other co-existing sequelae of diabetes mellitus, specific metabolic factors as well as the need for fertility treatment. However, evidence for treatment of ejaculatory dysfunction, especially delayed ejaculation and retrograde ejaculation, is based on low-level evidence comprising small sample-size series and retrospective or cross-sectional studies. Whilst promising findings from large randomised controlled trials have provided strong evidence for the licensed treatment of premature ejaculation, similar robust studies are needed to accurately elucidate factors predicting ejaculatory dysfunction in diabetes mellitus, as well as for the development of pharmacotherapies for delayed ejaculation and retrograde ejaculation. Similarly, more contemporary robust data are required for fertility outcomes in these patients, including methods of sperm retrieval and assisted reproductive techniques in retrograde ejaculation.

Description of and Relationships among Potential Variables Supported for the Diagnosis of Delayed Ejaculation

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

The Unfinished Business of Defining Premature Ejaculation: The Need for Targeted Research

INTRODUCTION

Fifteen years have passed since the International Society of Sexual Medicine first established the 3-pronged criteria for premature ejaculation (PE): a short ejaculation latency, lack of ejaculatory control, and bother/distress. Although the process of establishing valid criteria for any condition or disorder is an ongoing one, a dearth of targeted research on these criteria has hindered professional societies from updating and revising them.

OBJECTIVES

To review and critique existing criteria used in the diagnosis of PE, to identify specific problems with them, and to recommend studies that will address shortcomings.

METHODS

Each of the PE criteria was evaluated and compared against standard procedures for establishing validated measures. Following each analysis, targeted research to address the gaps has been recommended.

RESULTS

Each PE criterion has shortcomings and each can be improved by using standard validation procedures, as noted by the targeted research outcomes. Professional societies can play an important role by encouraging broad participation in research that generates new and relevant data supporting, validating, or challenging the existing criteria.

CONCLUSION

The concepts underlying the diagnostic criteria for PE have both broad consensus and functional utility. Nevertheless, much of the research investigating PE has uncritically adopted these criteria without concomitantly recognizing their limitations. These limitations prevent determining accurate prevalence rates, interpreting research findings with confidence, and establishing efficacious treatment outcomes. Rowland DL, Althof SE, McMahon CG.

Delayed Ejaculation Due to Improper Male Condom Size: A Case Report

Introduction

Delayed ejaculation (DE) is a poorly understood and uncommon male sexual dysfunction. The etiology of DE includes psychological and biological factors, which are usually combined. Herein, we report a case of acquired and situational DE due to improper male condom size.

Aims

To identify and correct the possible cause of acquired and situational DE.

Methods

A male patient presented with new-onset DE for 6 months. His physical and mental examination was unremarkable. Laboratory results were all normal. He was diagnosed with acquired, situational DE and received sessions of sexual counseling. However, his DE persisted until he accidentally used a larger condom. He then reported normal orgasm.

Main outcome measures

Resolution of acquired and situational DE.

Results

His DE was improved after using a more proper condom size.

Conclusion

Most patients are believed to have psychological problems and proper condom use is under-recognized. To the best of our knowledge, this is the first report of DE caused by this etiology.

Moving Toward Empirically Based Standardization in the Diagnosis of Delayed Ejaculation

BACKGROUND

Criteria for delayed ejaculation (DE) rely on a long ejaculation latency (EL) time, lack of control/advancement regarding ejaculation, and associated bother/distress; yet, few studies have investigated these criteria in men who indicate the desire to ejaculate sooner during partnered sex.

AIM

To help standardize criteria for DE by better understanding characteristics of men who desire to ejaculate sooner during partnered sex in terms of their EL, reported ejaculatory control, and level of bother/distress, as well as their perceptions of typical and ideal ELs for men in general and of ELs for men with premature ejaculation (PE).

METHODS

A total of 572 men recruited through social media responded to an online survey regarding their EL, as well as typical, ideal, and PE ELs of men in general. They also rated (i) their ability to control and/or advance ejaculation and (ii) their level of associated bother/distress. 4 comparison groups were then established: men with probable DE (with [DE1] and without [DE2] ejaculatory control issues), a reference group with no ejaculatory disorders, and men who identified as having PE.

OUTCOMES

To demonstrate differences in EL, ejaculatory control, and bother/distress between men with delayed ejaculation and the control and PE reference groups.

RESULTS

ELs for men with probable DE were twice as long as those with no ejaculatory disorders. When probable DE men were further subdivided into DE2 and DE1, differences were greater for the DE2 group. DE2 men also differed significantly from the reference group on ejaculatory control/advancement but not on bother/distress. Both DE and reference groups differed from the PE group.

CLINICAL IMPLICATIONS

Using both EL and ejaculatory control are useful in distinguishing men with delayed ejaculation from men without delayed ejaculation.

STRENGTHS & LIMITATIONS

A sizable sample drawn from a multinational population powered the study, whereas the use of social media for recruitment limited the generalizability of findings.

CONCLUSION

Both EL and ejaculatory control differentiate men with probable DE from a control reference group having no ejaculatory disorders. Differences in bother/distress did not emerge as significant. Implications for diagnosing men with DE are presented. Rowland DL, Cote-Leger P. Moving Toward Empirically Based Standardization in the Diagnosis of Delayed Ejaculation. J Sex Med 2020;17:1896-1902.

Estimations of Typical, Ideal, Premature Ejaculation, and Actual Latencies by Men and Female Sexual Partners of Men During Partnered Sex

BACKGROUND

The ejaculation latency (ELT) criterion for men with premature ejaculation (PE), including its 2 major subtypes of lifelong and acquired, relies heavily on expert opinion, yet such information represents only one source of data for this determination; furthermore, information regarding ELTs for PE within specific subgroups of men (eg, gay, bisexual) has been lacking.

AIM

To obtain data regarding men's lived experiences and expectations regarding typical ejaculation, ideal ejaculation, and PE and (for men) self-reported ejaculatory latencies during partnered sex across a variety a groups, including men vs women (ie, sexual partners of men), men with and without PE, and straight vs gay/bisexual men.

METHODS

We recruited 1,065 men and sexual partners of men, asking them to estimate typical ejaculation, ideal ejaculation, and PE and (for men) self-latencies through an online survey posted on social media. Demographics, sexual identity, and sexual response data were also collected.

RESULTS

Typical and self-reported ELTs were closely aligned with those reported in the literature, with ideal ELTs generally longer than typical ELTs. Median PE ELTs were consistently estimated around 1.5 min, with nearly all subgroups-men vs women; straight vs gay; PE and non-PE men-showing alignment on this criterion. Men with lifelong PE did not differ from men with acquired PE in either their PE ELT estimation or their self-reported ELT.

CLINICAL IMPLICATIONS

The data support the idea of extending the latency cutoff for establishing a PE diagnosis beyond the current 1-minute threshold.

STRENGTHS & LIMITATIONS

A large sample size drawn from a multinational population powered the study, whereas the use of social media for recruitment and lack of inclusion of lesbian and asexual individuals may have missed relevant data from some who have had sexual experience with men.

CONCLUSION

Straight and nonstraight men do not differ in their ELT estimations. In addition, the use of different ELT criteria for lifelong vs acquired PE may be unnecessary. Côté-Léger P, Rowland DL. Estimations of Typical, Ideal,Premature Ejaculation,and Actual Latencies by Men and Female Sexual Partners of Men During Partnered Sex. J Sex Med 2020;17:1448-1456.

Sexual Cognitions, Trait Anxiety, Sexual Anxiety, and Distress in Men With Different Subtypes of Premature Ejaculation and in Their Partners

This study examined trait anxiety and sexual cognitions in 610 men with premature ejaculation (PE) (DSM-IV-TR criteria) and in 107 partners of these men, and compared their scores to normative data. Sexual anxiety, intravaginal ejaculatory latency time, feeling of control over ejaculation, and PE-related distress were also assessed. The scores of 343 participants (56.23%) with clearly identifiable subtypes of PE according to Waldinger's classification system (lifelong, acquired, variable, and subjective subtypes) were compared in these domains. Finally, the predictive value of these factors in determining PE-related distress was explored. The following conclusions can be summarized from the results: (1) Men affected by PE are more distressed by the problem than their partners; (2) there is no evidence that levels of trait anxiety in individuals with PE are dissimilar to those found in the general population; (3) "dysfunctional" sexual cognitions likely play a role in PE, especially with regard to PE-related distress; (4) different subtypes of PE have similar profiles on measures of trait anxiety, sexual anxiety, and sexual cognitions; (5) differences between subtypes are only apparent with regard to feeling of control over ejaculation, with men with lifelong or acquired PE scoring significantly lower than those with a subjective form of the problem.

Serotonergic polymorphisms in the control of ejaculation

Serotonin has long been implicated in the regulation of the processes that trigger the ejaculatory reflex. Most evidence of serotonergic involvement is, however, indirect, stemming either from studies on rodents or clinical trials investigating effects of serotonergic drugs. In the past decade, emerging evidence for heritability (i.e., genetic effects) of premature ejaculation (PE) symptoms has spawned a number of scholarly attempts to identify genes that regulate ejaculation, most of which have focused on candidate genes related to the serotonergic system. The aim of the present review article was to summarize the literature concerning genetic association studies of PE, with focus on serotonergic genes. However, methodological obstacles relating to the candidate gene approach predict that a priori hypotheses regarding candidate genes are likely to generate ambiguous and spurious results if samples (e.g., if samples are underpowered and/or stratified). Attempts to replicate reported novel associations between PE symptoms and serotonergic candidate genes have largely failed (thereby adding to the growing body of evidence casting doubt on the reliability of the candidate gene approach), and at present, it is not possible to determine with acceptable certainty which serotonergic genes, if any, are involved in ejaculatory function.

Delayed Ejaculation: Pathophysiology, Diagnosis, and Treatment

Delayed ejaculation (DE) is a poorly defined and uncommon form of male sexual dysfunction, characterized by a marked delay in ejaculation or an inability to achieve ejaculation. It is often quite concerning to patients and their partners, and sometimes frustrates couples' attempts to conceive. This article aims to review the pathophysiology of DE and anejaculation (AE), to explore our current understanding of the diagnosis, and to present the treatment options for this condition. Electronic databases were searched from 1966 to October 2017, including PubMed (MEDLINE) and Embase. We combined “delayed ejaculation,” “retarded ejaculation,” “inhibited ejaculation,” or “anejaculation” as Medical Subject Headings (MeSH) terms or keywords with “epidemiology,” “etiology,” “pathophysiology,” “clinical assessment,” “diagnosis,” or “treatment.” Relevant sexual medicine textbooks were searched as well. The literature suggests that the pathophysiology of DE/AE is multifactorial, including both organic and psychosocial factors. Despite the many publications on this condition, the exact pathogenesis is not yet known. There is currently no single gold standard for diagnosing DE/AE, as operationalized criteria do not exist. The history is the key to the diagnosis. Treatment should be cause-specific. There are many approaches to treatment planning, including various psychological interventions, pharmacotherapy, and specific treatments for infertile men. An approved form of drug therapy does not exist. A number of approaches can be employed for infertile men, including the collection of nocturnal emissions, prostatic massage, prostatic urethra catheterization, penile vibratory stimulation, probe electroejaculation, sperm retrieval by aspiration from either the vas deferens or the epididymis, and testicular sperm extraction.
