RESUMO

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.

RESUMO

BACKGROUND: Criteria for the definition and diagnosis of delayed ejaculation (DE) are yet under consideration. AIM: This study sought to determine an optimal ejaculation latency (EL) threshold for the diagnosis of men with DE by exploring the relationship between various ELs and independent characterizations of delayed ejaculation. METHODS: In a multinational survey, 1660 men, with and without concomitant erectile dysfunction (ED) and meeting inclusion criteria, provided information on their estimated EL, measures of DE symptomology, and other covariates known to be associated with DE. OUTCOMES: We determined an optimal diagnostic EL threshold for men with DE. RESULTS: The strongest relationship between EL and orgasmic difficulty occurred when the latter was defined by a combination of items related to difficulty reaching orgasm and percent of successful episodes in reaching orgasm during partnered sex. An EL of ≥16 minutes provided the greatest balance between measures of sensitivity and specificity; a latency ≥11 minutes was the best threshold for tagging the highest number/percentage of men with the severest level of orgasmic difficulty, but this threshold also demonstrated lower specificity. These patterns persisted even when explanatory covariates known to affect orgasmic function/dysfunction were included in a multivariate model. Differences between samples of men with and without concomitant ED were negligible. CLINICAL IMPLICATIONS: In addition to assessing a man's difficulty reaching orgasm/ejaculation during partnered sex and the percent of episodes reaching orgasm, an algorithm for the diagnosis of DE should consider an EL threshold in order to control diagnostic errors. STRENGTHS AND LIMITATIONS: This study is the first to specify an empirically supported procedure for diagnosing DE. Cautions include the use of social media for participant recruitment, relying on estimated rather than clocked EL, not testing for differences between DE men with lifelong vs acquired etiologies, and the lower specificity associated with using the 11-minute criterion that could increase the probability of including false positives. CONCLUSION: In diagnosing men with DE, after establishing a man's difficulty reaching orgasm/ejaculation during partnered sex, using an EL of 10 to 11 minutes will help control type 2 (false negative) diagnostic errors when used in conjunction with other diagnostic criteria. Whether or not the man has concomitant ED does not appear to affect the utility of this procedure.

RESUMO

PURPOSE: Men who ejaculate before or shortly after penetration, without a sense of control, and who experience distress related to this condition may be diagnosed with premature ejaculation (PE), while men who experience difficulty achieving sexual climax may be diagnosed with delayed ejaculation (DE). The experience of many clinicians suggest that these problems are not rare and can be a source of considerable embarrassment and dissatisfaction for patients. The role of the clinician in managing PE and DE is to conduct appropriate investigation, to provide education, and to offer available treatments that are rational and based on sound scientific data. MATERIALS AND METHODS: The systematic review utilized to inform this guideline was conducted by a methodology team at the Pacific Northwest Evidence-based Practice Center. A research librarian conducted searches in Ovid MEDLINE (1946 to March 1, 2019), the Cochrane Central Register of Controlled Trials (through January 2019) and the Cochrane Database of Systematic Reviews (through March 1, 2019). An update search was conducted on September 5, 2019. Database searches resulted in 1,851 potentially relevant articles. After dual review of abstracts and titles, 223 systematic reviews and individual studies were selected for full-text dual review, and 8 systematic reviews and 59 individual studies were determined to meet inclusion criteria and were included in the review. RESULTS: Several psychological health, behavioral, and pharmacotherapy options exist for both PE and DE; however, none of these pharmacotherapy options have achieved approval from the United States Food and Drug Administration and their use in the treatment of PE and DE is considered off-label. CONCLUSION: Disturbances of the timing of ejaculation can pose a substantial impediment to sexual enjoyment for men and their partners. The Panel recommends shared decision-making as fundamental in the management of disorders of ejaculation; involvement of sexual partner(s) in decision making, when possible, may allow for optimization of outcomes.

RESUMO

Delayed ejaculation belongs to the group of sexual disorders in men. The causes of delayed ejaculation or anejaculation are not exactly known. It is assumed that it can be caused by psychogenic or organic influences or their combinations. One of the causes of delayed ejaculation may be elevated prolactin levels, which may be increased by psychosocial stress, pituitary disorders or also treatment with selective serotonin reuptake inhibitors in the treatment of depression. We tested a selected group of 50 men who were diagnosed with a depressive disorder and whose antidepressant treatment lasted for at least 24 weeks. These patients reported long-term delayed ejaculation or, in some cases, anejaculation as comorbidity. The results showed significant Spearman's correlation between elevated prolactin levels and intravaginal ejaculation latency values (R = 0.45), as well as between Beck's Depression-II inventory and intravaginal ejaculation latency and latency values (R = 0.48).

RESUMO

BACKGROUND: It is unclear whether men who experience sexual difficulty during partnered sex experience similar difficulty during masturbation. AIM: To determine whether sexual functionality and dysfunctionality were similar or different during masturbation vs partnered sex. METHODS: We compared sexual responsivity during masturbation vs partnered sex in a multinational sample of 4,209 men with and without a sexual dysfunction to determine whether dysfunctionality was greater, less, or about the same during these 2 types of sexual activity. OUTCOMES: Consistently lower impairment of sexual function was found during masturbation compared with partnered sex for all 3 sexual problems assessed: erectile dysfunction, premature ejaculation, and delayed ejaculation. CLINICAL TRANSLATION: These findings reiterate the potential value of assessing sexual responsivity during masturbation as well as melding masturbation strategies with couples therapy in order to attenuate impaired response during partnered sex. STRENGTH & LIMITATIONS: Although this study provides the first empirical evidence based on a large multinational sample indicating that sexual functionality is consistently higher during masturbation than partnered sex, it does not provide an empirically-derived explanation for this difference. CONCLUSION: Understanding a man's response potential during masturbation may be important to improving sexual response during partnered sex, with the need for more targeted research that more directly evaluates the use of such strategies in the treatment of men's sexual problems.

RESUMO

Research into ejaculatory dysfunction in sexual activities other than penovaginal intercourse is limited due to the absence of well-defined tools to measure ejaculatory latencies in these sexual activities. Our pilot study using Arousal to Ejaculation Time Interval (AETI) and Erection to Ejaculation Time Interval (EETI) as tools to measure ejaculatory latencies in different types of sexual encounters in medical professionals had yielded promising results. Hence, we conducted a similar study using AETI and EETI as tools, measured using stopwatch in healthy, sexually active heterosexual male population in a multinational sample from January 2018 to December 2020. Though mean AETI and EETI differed in different sexual activities, on analysing them across all sexual activities, mean AETI and EETI in normal ejaculators, premature ejaculators and delayed ejaculators were 10.3 ± 5.81 min and 6.8 ± 4.13 min, 4.31 ± 2.98 min and 3.35 ± 3.06 min and 20.9 ± 16.1 min and 16.3 ± 10.6 min respectively. Both AETI and EETI were significantly different from normal to premature as well as normal to delayed ejaculators (p-value < 0.05). It could be concluded that these novel tools can help to measure ejaculatory latencies in sexual activities in heterosexual males.

RESUMO

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.

RESUMO

BACKGROUND: Mechanisms underlying delayed orgasm (DO) are poorly understood; however, known effects of psychotropic medications on sexual function provides a rationale for aberrant central nervous system signaling as a cause. AIM: To compare brain activation between men with normal orgasm and those with lifelong DO during sexual stimulation using brain fMRI algorithms. METHODS: 3 subjects with self-reported life-long DO and 6 normal controls were included in this study. The International Index of Erectile Function, Male Sexual Health Questionnaire, and self-reported time to orgasm were used to assess sexual function. Subjects underwent a 3-T fMRI study while viewing 3 video clips: a neutral control (NC), a positive emotional control (EC), and a sexual condition (SC). Each video sequence was repeated 5 times, with 50-second clips presented in a randomized fashion. fMRI data were analyzed in a block design manner to determine areas of differential brain activation between groups. The Allen Brain Atlas of gene expression in the human brain was used to identify signaling pathways in the areas of differential fMRI activation between the DO and control groups. OUTCOMES: The primary outcome was differential activation of fMRI neural activation between groups. RESULTS: Analysis of differential activation in the SC compared with the NC and EC revealed increased activation in the right frontal operculum (P = .003), right prefrontal gyrus (P = .003), and inferior occipital gyrus (P = .003). Increased activation in the right fusiform gyrus of the occipital lobe and the right hippocampus (P = .0004) was seen in the DO group compared with controls. Using the Allen Atlas of Human Brain Expression, we identified corresponding neurotransmitter receptors to this region, including adenosine receptors, muscarinic and nicotinic cholinergic receptors, cannabinoid receptors, and dopamine receptors, among others. CLINICAL IMPLICATIONS: Lifelong DO in men may be due to abnormal neurotransmitter signaling leading to poor progression of arousal due to aberrant processing of sexual cues. Identification of neurotransmitter pathways by fMRI will aid the development of pharmacotherapeutic agents. STRENGTHS & LIMITATIONS: Strengths of this study include the novel application of functional neuroimaging to investigate the pathogenesis of DO. Limitations include the small sample size, making this study exploratory in nature. CONCLUSION: This study revealed differences in brain activation on visualization of sexual stimuli in men with a history of DO compared with controls. Identified regions are rich in numerous neurotransmitter receptor subtypes and may be amenable to pharmacologic targeting to identify novel therapies for these men.

RESUMO

BACKGROUND: Ejaculatory dysfunction (EjD) is a complex pathological condition compared to erectile dysfunction (ED). A definitive classification of EjD is not established, and treatment is often delayed. Owing to its association with infertility, EjD is a serious concern, particularly in men of reproductive age. METHODS: The authors performed a literature search to identify the latest articles and overseas guidelines for review. RESULTS: Our new classification categorizes men into two groups as follows: (1) men with inability to ejaculate (retrograde ejaculation, anejaculation, intravaginal ejaculatory dysfunction) and (2) men requiring an abnormal time for ejaculation (premature ejaculation, delayed ejaculation). In Japan, the number of men presenting with an inability to ejaculate is greater than those presenting with premature ejaculation. Pharmacotherapy is the first-line treatment for the management of these EjD patients. Behavioral therapy is added to pharmacotherapy depending on the case. Penile vibratory stimulation or electroejaculation is indicated in some men with retrograde ejaculation and anejaculation. In cases who hope for a baby, assisted reproductive technology should be simultaneously considered not to waste time. CONCLUSION: It is important to distinguish between EjD and ED and accurately diagnose the type of EjD for optimal treatment of this condition.

RESUMO

Delayed ejaculation is a form of sexual disorders, which is characterized by constant or intermittent delays or absence of ejaculation and orgasm, despite normal sexual arousal and erectile function. Delayed ejaculation is one of the most studied and rare types of male sexual dysfunctions, which leads to depression, anxiety, and often is a reason of low self-esteem, reduced satisfaction of a man with his partner, and worsening of relationships between partners. In some cases, delayed ejaculation and anejaculation cause infertility. Current views on epidemiology, diagnostics and treatment strategy of delayed ejaculation are presented in the article.

RESUMO

BACKGROUND: Although delayed ejaculation (DE) is typically characterized as a persistently longer than anticipated or desired time to ejaculation (or orgasm) during sexual activity, a timing-based definition of DE and its association with serum testosterone has not been established in a large cohort. AIM: To examine in an observational study estimated intravaginal ejaculatory latency time (IELT) and masturbatory ejaculation latency time (MELT) in men self-reporting DE, assess the association of IELT and MELT with serum testosterone levels, and determine whether correlation with demographic and sexual parameters exist. METHODS: Men who resided in the United States, Canada, and Mexico were enrolled from 2011 to 2013. Self-estimated IELT and MELT were captured using an Ejaculatory Function Screening Questionnaire in a sample of 988 men screened for possible inclusion in a randomized clinical trial assessing testosterone replacement therapy for ejaculatory dysfunction (EjD) and who self-reported the presence or absence of DE and symptoms of hypogonadism. Additional comorbid EjDs (ie, anejaculation, perceived decrease in ejaculate volume, and decreased force of ejaculation) were recorded. Men with premature ejaculation were excluded from this analysis. IELT and MELT were compared between men self-reporting DE and men without DE. The associations of IELT and MELT with serum testosterone were measured. OUTCOMES: IELT, MELT, and total testosterone levels. RESULTS: Sixty-two percent of screened men self-reported DE with or without comorbid EjDs; 38% did not report DE but did report at least one of the other EjDs. Estimated median IELTs were 20.0 minutes for DE vs 15 minutes for no DE (P < .001). Estimated median MELTs were 15.0 minutes for DE vs 8.0 minutes for no DE (P < .001). Ejaculation time was not associated with serum testosterone levels. Younger men and those with less severe erectile dysfunction had longer IELTs and MELTs. CLINICAL IMPLICATIONS: Estimated ejaculation times during vaginal intercourse and/or masturbation were not associated with serum testosterone levels in this study; thus, routine androgen evaluation is not indicated in these men. STRENGTHS AND LIMITATIONS: This large systematic analysis attempted to objectively assess the ejaculation latency in men with self-reported DE. Limitations were that ejaculation time estimates were self-reported and were queried only once; the questionnaire did not distinguish between failure to achieve orgasm and ejaculation; and assessment of DE was limited to heterosexual vaginal intercourse and masturbation. CONCLUSION: IELT and MELT were longer in men with DE, and there was no association of ejaculation times with serum testosterone levels in this study population.

RESUMO

INTRODUCTION: Ejaculatory dysfunctions other than premature ejaculation are commonly encountered in specialized clinics; however, their characterization in community-dwelling men is lacking. AIM: The aim of this study was to evaluate the prevalence, severity, and associated distress of four ejaculatory dysfunctions: delayed ejaculation (DE), anejaculation (AE), perceived ejaculate volume reduction (PEVR) and/or decreased force of ejaculation (DFE) as a function of demographic and clinical characteristics in men. METHODS: Observational analysis of 988 subjects presenting with one or more types of ejaculatory dysfunctions other than premature ejaculation who screened for a randomized clinical trial assessing the efficacy of testosterone replacement on ejaculatory dysfunction. Demographic and clinical characteristics were assessed as potential risk factors using regression analysis. MAIN OUTCOME MEASURES: The main outcome measures used were ejaculatory dysfunction prevalence and scores (3-item Men's Sexual Health Questionnaire Ejaculatory Dysfunction-Short Form [MSHQ-EjD-SF]), and bother (MSHQ-EjD-SF Bother item) and sexual satisfaction/enjoyment (International Index of Erectile Function Questionnaire Q7, Q8) as a function of subject's age, race, body mass index (BMI) and serum testosterone levels (measured by liquid chromatography tandem mass spectrometry). RESULTS: Mean (standard deviation [SD]) age of the participants was 52 years (11). Eighty-eight percent of the men experienced more than one type of ejaculatory dysfunction and 68% considered their symptoms to be bothersome. Prevalence of the ejaculatory dysfunctions was substantial across a range of age, race, BMI, and serum testosterone categories. Prevalence of PEVR and DFE were positively associated with age (<40 years vs. 60-70 years: PEVR: odds ratio [OR], 3.05; 95% confidence interval [CI], 1.32-7.06; DFE: OR, 2.78; 95% CI, 1.46-5.28) while DFE was associated with BMI (≥30 kg/m(2) vs. < 25 kg/m(2) : OR, 1.80; 95% CI, 1.062-3.05). All ejaculatory dysfunctions were more prevalent in black men. CONCLUSION: The majority of the participants experienced multiple ejaculatory dysfunctions and found them to be highly bothersome. Ejaculatory dysfunctions were prevalent across a wide range of demographic and clinical characteristics.

RESUMO

INTRODUCTION: The sexually sluggish (SLG) male rat has been proposed as an animal model for the study of lifelong delayed ejaculation, a sexual dysfunction for which no treatment is available. Low endocannabinoid anandamide (AEA) doses facilitate sexual behavior display in normal sexually active and in noncopulating male rats through the activation of CB1 receptors. AIM: To establish whether low AEA doses reduced the ejaculatory threshold of SLG male rats by acting at CB1 receptors. METHODS: SLG male rats were intraperitoneally injected with different doses of AEA (0.1-3.0 mg/kg), the CB1 receptor antagonist AM251 (0.1-3.0 mg/kg), or their vehicles and tested for copulatory behavior during 60 minutes. Animals receiving AEA effective doses were subjected to a second sexual behavior test, 7 days later under drug-free conditions. To determine the participation of CB1 receptors in AEA-induced actions, SLG rats were pretreated with AM251 prior to AEA. MAIN OUTCOME MEASURES: The sexual parameters, intromission latency, number of mounts and intromissions, ejaculation latency, and interintromission interval. RESULTS: All sexual behavior parameters of SLG rats were significantly increased when compared with normal sexually experienced animals. Low AEA doses (0.3 and 1 mg/kg) significantly lowered the ejaculatory threshold of SLG rats, reducing the number of pre-ejaculatory intromissions and ejaculation latency. IL, M number, and locomotor activity were unaffected by AEA. Facilitation of the ejaculatory response of SLG rats disappeared 7 days after AEA injection. AM251 lacked an effect on copulation of SLG rats but blocked the AEA-induced lowering of the ejaculatory threshold. CONCLUSIONS: AEA appears to specifically target the ejaculatory threshold of SLG rats through the activation of CB1 receptors. This specificity along with the fact that AEA's effects are exerted acutely and at low doses makes this drug emerge as a promising treatment for the improvement of the ejaculatory response in men with primary delayed ejaculation.

RESUMO

Ejaculatory dysfunction is a common complaint and is often associated with a reduced quality of life for sufferer and partner. The spectrum of ejaculatory dysfunction extends from premature ejaculation (PE) to delayed ejaculation (DE) and anejaculation. Over the past 20-30 years, the PE treatment paradigm, previously limited to behavioural psychotherapy, has expanded to include drug treatment. Multiple well-controlled, evidence-based studies have demonstrated the efficacy and safety of selective serotonin re-uptake inhibitors in delaying ejaculation, confirming their role as first-line agents for the treatment of lifelong and acquired PE. More recently, there has been increased attention to the psychosocial consequences of PE, its epidemiology, its aetiology and its pathophysiology by both clinicians and the pharmaceutical industry. DE and anejaculation are probably the least common, least studied and least understood of the male sexual dysfunctions. However, their impact is significant as they may result in a lack of sexual fulfilment for both the man and his partner, an effect further compounded when procreation is among the couple's goals of sexual intercourse. The causes of DE, anejaculation and anorgasmia are manifold. Numerous psychotherapeutic treatments are described for the management of delayed or anejaculation. Although some appear to be effective, none has been properly evaluated in large-scale samples. Treatment of DE or anejaculation with pharmacotherapy has met with limited success. No drugs have been approved by regulatory agencies for this purpose, and most drugs that have been identified for potential use have limited efficacy, impart significant side-effects or are yet considered experimental in nature.

RESUMO

Sexual dysfunction is a common problem for patients taking antidepressants, with the highest prevalence rates observed with selective serotonin reuptake inhibitors (SSRIs). Sexual dysfunction can be distressing for patients and may lead to medication non-adherence; thus, it is important for the prescribers to be aware of the available treatment strategies, as well as of the strength of the evidence that supports their use. We present the case of a patient who developed delayed ejaculation after the initiation of sertraline for the treatment of depression. The patient's sexual dysfunction resolved after the addition of buspirone. A discussion of this case is followed by a review of the existing literature examining the possible role of buspirone in the treatment of SSRI-induced sexual dysfunction.

RESUMO

6-Nitrodopamine (6-ND) is released from human vas deferens and plays a modulatory role in the male ejaculation. Therapeutical use of α1-adrenoceptor antagonists is associated with ejaculatory abnormalities. To evaluate the effect of α1-adrenoceptor antagonists on the contractions induced by 6-ND, dopamine, noradrenaline, and adrenaline in the human epididymal vas deferens (HEVD). HEVD strips were suspended in glass chambers containing heated and oxygenated Krebs-Henseleit's solution. Cumulative concentration-response curves to catecholamines (10 nM-300 µM) were constructed in HEVD strips pre-incubated (30 min) with doxazosin (0.1-1 nM), tamsulosin (1-10 nM), prazosin (10-100 nM) and/or silodosin (0.1-10 nM). The effects of these α1-adrenoceptor antagonists were also evaluated in the electric-field stimulation (EFS, 2-32 Hz)-induced contractions. Doxazosin (0.1 nM) caused significant reductions in 6-ND-induced HEVD contractions without affecting the contractions induced by dopamine, noradrenaline, and adrenaline. Similar results were observed with tamsulosin (1 nM) and prazosin (10 nM). At these concentrations, these α1-adrenoceptor antagonists largely reduced the EFS-induced contractions. Silodosin (1 nM) caused concentration-dependent rightward shifts of the concentration-response curves to 6-ND but had no effect on the contractions induced by dopamine and adrenaline. Silodosin (0.1 nM) only inhibited the contractions induced by noradrenaline. Silodosin at 1 nM, but not at 0.1 nM, caused significant reductions in the EFS-induced contractions. The results reinforce the concept that 6-ND plays a major role in the human vas deferens contractility and indicate that the ejaculation disorders caused by doxazosin, tamsulosin, prazosin and silodosin cause in man, may be due to inhibition of the contractions induced by 6-ND rather than by the classical catecholamines dopamine, noradrenaline, and adrenaline.

RESUMO

BACKGROUND: Social platforms such as YouTube have become sources of information about diseases as they can be easily and rapidly accessed. However, this also has the risk of ill-intentioned content and misleading information. OBJECTIVE: To evaluate the reliability of YouTube video content about delayed ejaculation treatment. MATERIAL AND METHODS: YouTube videos were searched using the terms "delayed ejaculation," "retarded ejaculation," "inhibited ejaculation," and "anejaculation." Videos were excluded if they were not in English, were not related to the subject, or did not have audio and visual content. In accordance with the scientifically proven accurate information, the videos were separated as reliable (Group 2, n: 112) and unreliable videos (Group 1, n: 94). The groups were compared in respect of the video characteristics, and the scores obtained in the DISCERN-5, Global Quality Scale, the Patient Education Materials Assessment Tool Audiovisual, and the Journal of the American Medical Association scales. Intraclass correlation test was used to evaluate the level of agreement between the two investigators. RESULTS: Of the 1200 videos, 994 were excluded. No significant difference was determined between the Group 1 and Group 2 in respect of the median number of views [1672 (4555) vs 1547 (28,559), p = 0.63] and likes [10 (42) vs 17 (255), p = 0.07]. There was a greater number of videos in the Group 2 (54.4%) and the points obtained on the scoring scales were significantly higher than the Group 1 (p < 0.001). The videos originating from universities/professional organizations/non-profit physician/physician group were comprised the majority of the reliable videos (55.3%) and the unreliable videos had more content related to treatment (71.4%) (p < 0.001). CONCLUSION: Although there was a greater number of reliable videos related to the problem of delayed ejaculation, the content could be misleading and should be avoided by patients seeking treatment without consulting a physician.

RESUMO

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.

RESUMO

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.

RESUMO

INTRODUCTION: The "lost penis syndrome" (LPS) is a term often used in non-clinical settings to describe the subjective perception of the loss of cutaneous and proprioceptive feelings of the male organ during vaginal penetration. Although deserving clinical attention, this syndrome did not receive any consideration in the medical literature. Notwithstanding, it represents a relatively unexceptional condition among patients in sexual medicine clinics, and it is often reported together with other sexual dysfunctions, especially delayed ejaculation, anejaculation, male anorgasmia and inability to maintain a full erection. OBJECTIVES: To draft a new conceptual characterization of the LPS, defined as a lack of penile somesthetic sensations during sexual penetration due to various causes and leading to several sexual consequences in both partners. METHODS: Based on an extensive literature review and physiological assumptions, the mechanisms contributing to friction during penovaginal intercourse, and their correlation to LPS, have been explored, as well as other nonanatomical factors possibly contributing to the loss of penile sensations. RESULTS: Efficient penile erection and sensitivity, optimal vaginal lubrication and trophism contribute to penovaginal friction. Whenever one of these processes does not occur, loss of penile sensation defined as LPS can occur. Sociocultural, psychopathological and age-related (ie, couplepause) factors are also implicated in the etiology. Four types of LPS emerged from the literature review: anatomical and/or functional, behavioral, psychopathological and iatrogenic. According to the subtype, a wide variety of treatments can be employed, including PDE5i, testosterone replacement therapy and vaginal cosmetic surgery, as well as targeted therapy for concomitant sexual comorbidity. CONCLUSION: We held up the mirror on LPS as a clinically existing multifactorial entity and provided medical features and hypotheses contributing to or causing the occurrence of LPS. In the light of a sociocultural and scientific perspective, we proposed a description and categorization of this syndrome hypothesizing its usefulness in daily clinical practice.
