A Review of Pathophysiology and Management Options for Delayed Ejaculation

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.

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.

Therapeutic efficacy and safety of a free-standing motorized ejaculation aid for patients with intravaginal ejaculatory dysfunction

Purpose

There are no approved drugs or devices for the treatment of intravaginal ejaculation disorders, and treatment is often difficult. This study aimed to evaluate the efficacy and safety of the A10 Cyclone SA + PLUS® ejaculation aid (Rends Co., Ltd., Chiba, Japan), which allows the user to adjust the intensity of stimulation, for intravaginal ejaculation disorders.

Methods

Each participant was instructed to perform practice masturbation with the A10 Cyclone SA + PLUS to simulate vaginal ejaculation. After 8 weeks of training, the participants were asked about their intravaginal ejaculation status. Sexual function was also evaluated before and after the training using several specific questionnaires, including the numerical rating scale for ejaculatory satisfaction.

Results

Among the 10 participants (41.5 ± 3.21 years) who completed the training and questionnaire evaluation, four (40%) became capable of intravaginal ejaculation. The questionnaire evaluation showed predominant improvement after training in the ejaculation-capable group according to the numerical rating scale, which expresses satisfaction with ejaculation. The participants experienced no significant adverse events.

Conclusion

As no effective treatment currently exists for intravaginal ejaculation disorders, we conclude that the A10 Cyclone SA + PLUS may be one treatment tool for intravaginal ejaculation disorders with good efficacy and no adverse events.

Management strategies of sexual dysfunctions in Parkinson's disease

Sexual dysfunctions (SD) are frequent and highly disabling nonmotor manifestations of Parkinson's disease (PD) but are also potentially treatable. Neurologists should actively discuss, recognize and treat sexual health issues as an integral part of the management of the disease. In this chapter, we provide recommendations for managing and treating both primary and secondary SD in PD. Many sexual problems can be, at least partially, improved by adjusting the treatment of motor, nonmotor symptoms and comorbidities. Although some treatments of primary SD are evidence-based, many therapeutic options have not been yet systematically studied in patients with PD. The development of new treatments and repurposing of existing remedies in patients with PD remain an unmet need.

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.

Management Options for Premature Ejaculation and Delayed Ejaculation in Men

INTRODUCTION

Many men experience distressing issues regarding the timing of orgasm and ejaculation, such as premature ejaculation (PE) and delayed ejaculation (DE). Despite being highly prevalent, both PE and DE are poorly understood and present a management challenge for sexual medicine specialists.

AIM

To summarize existing data on the medical management of PE and DE.

METHODS

A comprehensive literature review pertaining to the management of PE and DE was conducted using PubMed and clinicaltrials.gov for data published up until May 2019. Our focus was on double-blind, placebo-controlled trials and meta-analyses of such studies.

MAIN OUTCOME MEASURE

Peer-reviewed studies on treatment options for PE and DE were critically analyzed for results and methodological rigor.

RESULTS

The peer-reviewed data on PE management continue to evolve. Psychotherapy, pharmacotherapy, and procedural interventions have all been associated with some degree of efficacy. A strong evidence base supports the off-label use of selective serotonin reuptake inhibitors and local anesthetics in PE given consistent increases in ejaculation latency time. Education and mental health assessments remain important components of PE management despite a dearth of peer-reviewed data on these interventions. Numerous treatment strategies have been evaluated for DE; limited data support psychotherapy, pharmacotherapy, and/or penile vibratory stimulation as management options.

CONCLUSION

A number of management options for PE or DE exist but none has been formally approved by the US Food and Drug Administration. New and novel treatments would be of great value in managing issues regarding the timing of ejaculation/orgasm. Martin-Tuite P, Shindel AW.

Contemporary management of ejaculatory dysfunction

Although erectile dysfunction is the most common disorder of male sexual health, ejaculatory dysfunction is the most common form of sexual dysfunction experienced by men. Ejaculatory dysfunction covers a broad range of disorders that we have divided into four main categories: premature ejaculation, delayed ejaculation (DE)/anorgasmia, unsatisfactory sensation of ejaculation (including painful ejaculation and ejaculatory anhedonia), and absent ejaculate (including retrograde ejaculation and aspermia). We also cover several special scenarios including hematospermia, spinal cord injury and fertility with anejaculation. In this paper, we will review the anatomy and pathophysiology of normal ejaculation to establish the baseline knowledge of how this pathway can go awry. We will then briefly review the critical diagnostic criteria, pertinent steps in evaluation, risk factors, and causes (if known) for each of the ejaculatory disorders. Finally, the bulk of the paper will discuss current management strategies of each disorder.

A Novel Collaborative Protocol for Successful Management of Penile Pain Mediated by Radiculitis of Sacral Spinal Nerve Roots From Tarlov Cysts

INTRODUCTION

Since 14 years of age, the patient had experienced extreme penile pain within seconds of initial sexual arousal through masturbation. Penile pain was so severe that he rarely proceeded to orgasm or ejaculation. After 7 years of undergoing multiple unsuccessful treatments, he was concerned for his long-term mental health and for his future ability to have relationships.

AIM

To describe a novel collaboration among specialists in sexual medicine, neurophysiology, and spine surgery that led to successful management.

METHODS

Collaborating health care providers conferred with the referring physician, patient, and parents and included a review of all medical records.

MAIN OUTCOME MEASURE

Elimination of postpubertal intense penile pain during sexual arousal.

RESULTS

The patient presented to our sexual medicine facility at 21 years of age. The sexual medicine physician identifying the sexual health complaint noted a pelvic magnetic resonance imaging report of an incidental sacral Tarlov cyst. A subsequent sacral magnetic resonance image showed four sacral Tarlov cysts, with the largest measuring 18 mm. Neuro-genital testing result were abnormal. The neurophysiologist hypothesized the patient's pain at erection was produced by Tarlov cyst-induced neuropathic irritation of sensory fibers that course within the pelvic nerve. The spine surgeon directed a diagnostic injection of bupivacaine to the sacral nerve roots and subsequently morphine to the conus medullaris of the spinal cord. The bupivacaine produced general penile numbness; the morphine selectively decreased penile pain symptoms during sexual arousal without blocking penile skin sensation. The collaboration among specialties led to the conclusion that the Tarlov cysts were pathophysiologically mediating the penile pain symptoms during arousal. Long-term follow-up after surgical repair showed complete symptom elimination at 18 months after treatment.

CONCLUSION

This case provides evidence that (i) Tarlov cysts can cause sacral spinal nerve root radiculitis through sensory pelvic nerve and (ii) there are management benefits from collaboration among sexual medicine, neurophysiology, and spine surgery subspecialties.
