Prevalence Of Premature Ejaculation Research Articles

Updating, correcting, and calibrating the narrative about premature ejaculation.

The narrative surrounding premature ejaculation (PE) has developed and solidified over the past 25years. Unfortunately, portions of that narrative are outdated and do not reflect more recent conceptualizations or empirical findings regarding this disorder. In this review we sought to identify existing narratives about PE in need of updating and to provide revised narratives based on the recent research literature. Five PE narratives in need of revision were identified, including: the prevalence of PE, age-related differences in PE prevalence, a validated ejaculation latency (EL) for diagnosing PE, differences between lifelong and acquired PE subtypes, and the application of PE definitions beyond penile-vaginal intercourse. Extensive literature searches provided information supporting both the original narrative and the need for a revised narrative based on both consideration of more recent studies and reinterpretation of studies conducted since the establishment of the original narratives. For each selected topic, the prevailing narrative based on the extant literature was first presented, followed by discussion of accumulating evidence that challenges the existing narrative. Each section ends with a suggested revised PE narrative. In 2 instances, the revised narrative required significant corrections (eg, PE prevalence, validated EL for diagnosing PE); in 2 instances, it expanded on the existing narrative (eg, PE subtype differences, inclusion of partnered sexual activities beyond penile-vaginal intercourse); and in 2 other instances, it backed off prior conclusions that have since required rethinking (eg, age-related changes in PE, PE subtype differences). Finally, a brief review of the 3-pronged criteria for PE (EL, ejaculatory control, and bother/distress) is presented and discussed. This review reiterates the dynamic state of research on PE and demonstrates the need for and value of ongoing research that not only addresses new issues surrounding this dysfunction but also challenges and revises some of the existing narratives about PE.

Prevalence and associated factors of premature ejaculation and erectile dysfunction in young, single men who have sex with men in Lima, Peru.

While there is literature on erectile dysfunction (ED) and premature ejaculation (PE) in men, conclusive evidence regarding these sexual health issues and potential associated factors in the young, single men who have sex with men (MSM) population is lacking. The study sought to determine the prevalence and factors associated with PE and ED in young single MSM in the capital of Peru. This was an analytical cross-sectional study in MSM using an online questionnaire. The presence of ED and PE was assessed using the 5-item International Index of Erectile Function and 5-item Premature Ejaculation Diagnostic Tool questionnaires, respectively. In addition, their association with personal, physical health, and sexual behavior variables was evaluated. Prevalence ratios (PRs) were estimated through regression models. Premature ejaculation and Erectile dysfunction in MSM. Of 315 participants, most were between 20 to 29years of age (71.8%), 43.5% identified as homosexual, 59.1% had between 2 and 5 sexual partners, and 40.6% reported that the duration of their sexual relationship was between 1 and 12months. The prevalence of ED was 53.3% (95% confidence interval [CI], 47.66%-58.95%), and PE was present in 8.3% (95% CI, 5.46%-11.86%). Factors associated with a higher prevalence of ED were having between 6 and 9 sexual partners (PR, 1.48; 95% CI, 1.05-2.11) and having a sexual relationship lasting 13 to 24months (PR, 0.70; 95% CI, 0.50-0.98). Furthermore, for each additional year from the onset of the first sexual encounter with another man, the prevalence of PE increased by 7% (PR, 1.07; 95% CI, 1.02-1.13). These findings suggest that there is a relationship between an increased number of sexual partners and a higher prevalence of ED. It also suggests that relationships that last for some time may have a protective effect against ED. Strengths include the use of validated instruments, adequate sample size, robust multivariate analysis, and being one of the few studies in Latin America assessing PE and ED in the MSM population. Limitations include the cross-sectional design, nonprobability sampling, and access to participants. Having more sexual partners is associated with increased ED, while relationships lasting 13 to 24months are associated with decreased ED. Each additional year from the onset of the first sexual relationship increases the prevalence of PE. These findings can guide the design of health policies and programs tailored to the MSM community to enhance their well-being and sexual quality of life.

The impact of hyperthyroidism on sexual functions in men and women: a systematic review and meta-analysis.

This study aimed to review the current knowledge on sexual dysfunction in men and women with hyperthyroidism through a systematic review and meta-analysis. Available clinical trials from the MEDLINE database were searched using a prerecorded protocol (Protocol Prospero ID: CRD42022340587), and obtained data were analyzed and reported according to the PRISMA guidelines. Pooled effect estimates were computed using a random-effects model. Twenty eligible studies were identified, of which 15 were included in this meta-analysis. The prevalence of erectile dysfunction was significantly higher in participants with hyperthyroidism than that in controls [odds ratio = 9.16 (95% confidence interval [CI], 5.0-16.5)]. Treatment of hyperthyroidism alone improved erectile functions [effect size, ES = 0.36 (95% CI, -0.01-72)] and mean intra-vaginal ejaculation latency time [ES = 0.63 (95% CI, 0.27-98)] among men with erectile dysfunction and/or premature ejaculation. The prevalence of premature ejaculation also decreased with treatment of hyperthyroidism [odds ratio = 0.11 (95% CI, 0.04-28). Women with hyperthyroidism demonstrated higher odds in female sexual dysfunction than controls [odds ratio = 4.34 (95% CI, 2.63-7.18)]. Female sexual function index scores in women with hyperthyroidism were also significantly lower than those in the controls with moderate effect sizes. An evident and reversible disruption of sexual functions under hyperthyroidism conditions was observed in both sexes.

Impact of type D personality and depressive symptoms on premature ejaculation in young adult males.

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

Prevalence, lifestyle, and risk factors of erectile dysfunction, premature ejaculation, and low libido in middle-aged men: first results of the Bavarian Men's Health-Study.

Erectile dysfunction (ED), premature ejaculation (PE), and low libido (LL) are reported as the most common male sexual dysfunctions. To evaluate the prevalence of ED, PE, and LL and associations with lifestyle risk factors and comorbidities in middle-aged men. This study included a population-based random sample of 2500 50-year-old men who completed validated questionnaires, including the International Index of Erectile Function, the Erection Hardness Score, the Sexual Complaints Screener, and further questionnaires. Multiple logistic regression of outcomes ED, PE, and LL was used to model the association with explanatory factors. The prevalence of at least one sexual dysfunction was 30%. 21%, 5.2%, and 7.2% of men had ED, PE, and LL, respectively. The risk of ED increased with PE (odds ratio [OR]: 1.94, 95% confidence interval [95%CI]: 1.22-3.08), LL (OR: 2.04, 95%CI: 1.26-3.29), higher waist circumference (OR: 2.23, 95%CI: 1.67-2.96), and lower urinary tract symptoms (LUTS) (OR: 1.88, 95%CI: 1.39-2.55), partnership was associated with a lower risk (OR: 0.57, 95%CI: 0.39-0.85). The risk of PE increased with ED (OR: 1.94, 95%CI: 1.23-3.07), partnership (OR:5.42, 95%CI: 1.30-22.60), depression (OR: 2.37, 95%CI: 1.09-5.14), and LUTS (OR: 2.42, 95%CI: 1.52-3.87), and decreased with physical activity (OR: 0.44, 95%CI: 0.21-0.93). The risk of LL increased with ED (OR: 2.09, 95%CI: 1.31-3.34) and poorer self-rated health (OR: 2.97, 95%CI: 1.54-5.71). Roughly one in three 50-year-old men experience some form of sexual dysfunction and risk factors identified in this study underline the multifactorial nature of ED, PE, and LL. Many risk factors are modifiable which underlines the role of patient education. Modifiable risk factors should be addressed in patient education and men should take active measures to remove the risk posed by these factors.

Population-level prevalence, effect on quality of life, and treatment behavior for erectile dysfunction and premature ejaculation in Poland

The prevalence of erectile dysfunction (ED) and premature ejaculation (PE) has been investigated in many population-based studies in different regions of the world. However, reliable data are lacking for Eastern Europe. Therefore, the aim of this study was to analyze the prevalence, effect on quality of life, and treatment-related behaviors for ED and PE in a population-representative sample of Polish men. We used an Internet interview format and rigorously adapted, widely accepted instruments for ED and PE evaluation. The study included 3001 men, representative for age and place of residence and adequate proportions of respondents from urban and rural areas. The prevalence of ED was 30.1–61.1%, and the prevalence of PE was 19.3–38.1%; there were no differences between urban and rural areas. Whereas the prevalence of ED increased with age, the prevalence of PE did not increase. More than 50% of respondents with ED and more than 60% of respondents with PE had concerns about their quality of life. However, less than one fourth of participants with ED and PE were seeking treatment, most of whom received treatment. The results of our nationwide analysis, reflecting the entire Polish population of men, are consistent with other epidemiologic studies of ED and PE and may support educational campaigns and health improvement programs in Poland.

Premature ejaculation prevalence among young men who have sex with men: a cross-sectional study with internet users in the metropolitan region of São Paulo, Brazil.

There are only a few studies about the prevalence and correlates of premature ejaculation (PE) among men who have sex with men (MSM). (1) To estimate PE prevalence according to 3 assessment methods: self-reported time from penetration to ejaculation (ejaculation latency time [ELT]); Premature Ejaculation Diagnostic Tool (PEDT); and a direct question about the self-perception of ejaculation as being normal, too early (premature), or retarded. (2) To assess the agreement of the 3 assessment methods and identify factors associated with PE according to each method and their combination. We evaluated data from 226 MSM who participated in a cross-sectional study about sexual behavior among men living in the metropolitan region of São Paulo, Brazil. They responded anonymously to an online survey between May 2019 and March 2020. We calculated the agreement of the 3 assessment methods and their association with other characteristics using logistic regression models. Outcomes included the prevalence of PE according to the assessment methods and the association measures (PE vs sociodemographic characteristics and sexual behavior). The prevalence of PE among MSM was 21.2% (95% CI, 16.1%-27.1%) according to the PEDT, 17.3% (95% CI, 12.6%-22.8%) per self-report, and 6.2% (95% CI, 3.4%-10.2%) by estimated ELT ≤2minutes. The agreement among the 3 assessments was fair (kappa, 0.31; 95% CI, 0.25-0.37; P < .001). Association with PE varied by assessment method: obesity and shorter time for ejaculation with anal sex vs masturbation were associated with PE according to the PEDT and ELT but not self-evaluation. Perception about ideal time to ejaculate ≤5minutes increased the chance of PE based on ELT. Higher chances of self-reported PE were associated with trying to hold back ejaculation, and lower chances were associated with higher frequencies of masturbation. Combining tools to investigate PE allows the identification of characteristics associated with this condition and may result in improvement in the care of MSM. This anonymous online survey provided the privacy necessary for participants to respond freely about sensitive questions, with a low risk of social adequacy bias. However, as it was a secondary analysis of a larger study, it could not evaluate comorbidities (eg, erectile dysfunction, prostatitis, depression) and the use of condoms. The prevalence of PE among MSM is high and varies according to the instrument used for the assessment, and the agreement among the 3 assessments was only fair.

Premature ejaculation among Chinese urban men: prevalence and correlates.

Premature ejaculation (PE) is a common male sexual dysfunction worldwide. It leads to substantial distress in men and their partners, constitutes a serious threat to the quality and stability of romantic relationships, and results in a decreased quality of life in a large part of the population. We investigated the prevalence of PE and correlated factors in an urban sample of Chinese men. In total, 1976 Chinese men aged 18 to 50 years responded to an online questionnaire regarding background information, present and previous sexual experience, frequency of different types of sex, as well as erectile and ejaculatory function. Participants' age, assigned sex at birth, sexual identity, relationship status, present and previous sexual experience, frequency of sexual activities, International Index of Erectile Function-5, and Checklist for Early Ejaculation Symptoms were used in the analyses. Forty-four (2.3%) participants had scores that were indicative or strongly indicative of PE, which was highly correlated with erectile problems. Men with more sexual experience (ie, more sexual partners and longer duration of being sexually active) had fewer ejaculatory problems. More frequent masturbation was associated with ejaculatory problems when controlling for age and education. More frequent partnered sex (ie, penile-vaginal sex) was associated with fewer ejaculatory problems. Ejaculation latency times for different types of sexual activities were positively correlated. The results indicated that ejaculatory problems have complex relationships with sexual experience that clinicians should be aware of. This study was the first to investigate PE with the Checklist for Early Ejaculation Symptoms as the measurement tool and the associations between PE and sexual experience, frequency of sexual activities, and sexual function in a large Chinese sample. However, self-reported ejaculation latency times may suffer from problems with validity. Men's sexual experience (ie, more sexual partners and longer duration of being sexually active) has an effect on their sexual function, which in turn affects their sexual activity.

High incidence of sexual dysfunction and timed intercourse was found only in infertile males who with known impairment of sperm quality for a long period: evidence from a hospital-based cross-sectional study

BackgroundInfertile men with higher sexual dysfunction risk and increased psychological burden, were also associated with more inclined to timed intercourse. Decreased semen quality may have adverse effects on male sexual function. However, it is also likely that many of these sequences do not play a direct role, those negative consequences may depend mainly on the later failed attempting pregnancy. Research is limited in this area.MethodsThis cross-sectional study was based on a group of 509 men who were assessed for couple’s infertility at the First Hospital of Jilin University between June 2021 and October 2021. All the men completed a comprehensive questionnaire, and then were divided in two groups. Group A included patients who either never received a routine infertility work-up or done so recently within the last 6 months. Group B included patients who previously received a sperm quality assessment at least 6 months or more prior. Patients were further categorized into three subgroups according to the severity of the decreases in their sperm parameters: severe, mild-moderate, and normozoospermic.ResultsThe prevalence of erectile dysfunction was higher in Group B Mild-Moderate and Group B Severe in comparison to Group A (OR=1.86 [1.07–3.24], P = 0.027; OR=5.312 [2.69–10.49], P < 0.001, respectively). No significant differences were found between Group A and Group B-normozoospermic. Similar results were observed in the prevalence of premature ejaculation between the groups. Timed intercourse was seen in 11.8% (20/170) of men in Group A and 16.2% (19/117) in Group B-normozoospermic. It was more commonly practiced among infertile men in Group B-Mild-Moderate and Group B Severe, as 28.2% (44/156) and 25.7% (17/66) of these couples had attempted to conceive through timed intercourse (P < 0.001).ConclusionsOur findings indicate that the severity of sperm quality impairment was negatively associated with sexual dysfunction only in infertile men who with known impairment of sperm quality for a long period. Timed intercourse was more common among these couples. For those individuals had never test their sperm quality, although more than half of these patients showed a decrease in sperm quality, the incidence of sexual dysfunction is relatively low and were comparable to those men examined previously known as normozoospermic.

Are the Criteria for the Diagnosis of Premature Ejaculation Applicable to Gay Men or Sexual Activities Other than Penile-Vaginal Intercourse?

IntroductionThe criteria for premature ejaculation (PE) have generally been limited to the diagnosis of heterosexual men engaging in penile-vaginal intercourse and therefore the applicability of PE diagnostic criteria to gay men and to activities beyond penile-vaginal intercourse has yet to be explored in depth.AimTo compare the prevalence of PE in gay and straight men and to assess whether PE-related diagnostic measures (ejaculatory control, ejaculation latency [EL], and bother/distress) can be applied with confidence to gay men or to men engaging in sexual activities other than penile-vaginal intercourse.MethodsGay and straight participants (n = 3878) were recruited to take an online survey assessing sexual orientation, sexual function/dysfunction (including specific PE-related measures), sexual relationship satisfaction, and various other sexual behaviors during partnered sex or masturbation.OutcomesComparison of ejaculatory control, EL, and bother/distress across gay and straight men, as well as across different types of sexual activities.ResultsA slightly lower PE prevalence among gay men became undetectable when other predictors of prevalence were included in a multivariate analysis (aOR = 0.87 [95% CI: 0.60–1.22]). Gay men with PE reported longer typical ELs (zU = -3.35, P < .001) and lower distress (zU = 3.68, P < .001) relative to straight men, but longer ELs and lower distress were also associated with anal sex.Clinical TranslationClinicians can feel confident about using existing criteria for the diagnosis of PE in gay men but should be aware of potentially longer ELs and lower PE-related bother/distress—probably related to the practice of anal sex—compared with straight men.Strengths and LimitationsAlthough well-powered and international in scope, this study was limited by biases inherent to online surveys, the lack of a sizable sample of bisexual men, and a lack of differentiation between men with acquired vs lifelong PE.ConclusionsIrrespective of sexual orientation, gay and straight men with PE reported shorter ELs, lower satisfaction, and greater bother/distress than functional counterparts. While PE-related diagnostic criteria (ejaculatory control, EL, and bother/distress) are applicable to gay men, accommodation for longer ELs and lower bother/distress in gay men should be considered.McNabney SM, Weseman CE, Hevesi K, et al.

Ayurvedic Management of Premature Ejaculation In Reference To Śukṟagata Vata: A Case Report

Premature ejaculation (PE) is the most common type of ejaculatory dysfunction which is difficult to manage. The global prevalence of PE is estimated as 20 – 40 % and in India it is reported as 8.76%. The inability to control ejaculation associated with unsatisfied experience of orgasm for the couples is a major factor causing psychological distress that leads to inter-personal conflicts. However, psychological interventions provide better results in PE, a combined approach of Psycho-Pharmacological intervention offer superior efficacy. A 39-year-old male presented with inability to delay ejaculation with a duration of sexual act less than 1 minute associated with resultant significant anxiety that hampered the sexual activity and reduced the sexual desire. On further interrogation, it was revealed that he had a significant stressful event in his life due to financial loss and also had a hurried sexual act which led to rapid ejaculation. However, he had many previous good experiences in his sexual act and also was having a supportive partner. The case was diagnosed as Premature ejaculation as per DSM V Criteria and as Śukṟagata Vata in Ayurveda purview. The management was planned in OP level, as a combination of a positive psychotherapy technique called Solution Focused Brief Therapy (SFBT) and an Ayurveda formulation Staṃbhanakara yoga for 3 months. Significant improvement was noted in Sexual dysfunction assessment questionnaire (Revised Singh. G et al. 2001) and Solution Focus Inventory recorded before and after the management along with increased Intra Ejaculatory Latency Time (IELT).

Advances and Missteps in Diagnosing Premature Ejaculation: Analysis and Future Directions

There are several problems with diagnostic criteria for premature ejaculation (PE) that lack objectivity, clarity and precision. They hamper accurate determination of PE prevalence estimates, investigations into the etiology of the dysfunction, impact on partners, development of validated Patient Reported Outcomes, regulatory authority oversight, and which men might benefit from specific treatment interventions. We sought to review, analyze and comment on the evolution of the definitions of PE and offer suggestions for future directions for PE definitions. Our goal is to propose strategies whereby the criterion sets are useful to researchers, clinicians and governmental oversight agencies alike and bring harmony and scientific rigor among the conflicting and confusing definitions. There are several premature ejaculation definitions published in the peer reviewed medical literature. The PUBMED electronic database from 1970 to 2021 was searched for published definitions. Search terms included the medical subject headings of premature ejaculation, definition and diagnosis. In chronological order, Table 1 lists the various diagnosis and criteria sets for PE. We discuss the process by which constructs, which make up diagnostic criteria sets, are operationalized and validated. We review definitions of PE beginning with Masters and Johnson's focus on partner orgasmic attainment and move through the nebulous and subjective criterion sets found in the early Diagnostic and Statistical Manuals and International Classification of Disease series, to the more evidenced-based definitions found in International Society of Sexual Medicine, Diagnostic and Statistical Manuals-5 and the American Urological Association (AUA) definitions. Additionally, we discuss how constructs and criteria sets have been adopted to minimize errors of inclusion and exclusion in defining disease/dysfunction. This manuscript offers a careful chronological analysis of the published definitions of PE. This historical lens allows the reader to perceive the shifting science underlying the development of PE definitions. The manuscript is limited regarding our comments on acquired PE as evidenced-based research is incomplete. Over the past 50 years there has been considerable forward momentum in defining PE based on well conducted scientific studies. We support the American Urological Association's modification in Intravaginal ejaculatory latency time to 2-minutes for lifelong PE, concur with the 11th revision of the International Classification of Diseases recommendation for changing the terminology from premature ejaculation to early ejaculation. We also recommend ongoing validation of definitions, moving away from the current heterosexist definition of PE based on penile-vaginal sex and urge further population based research into acquired PE to develop stronger evidenced-based criterion sets for this subtype.

The prevalence of premature ejaculation and its relationship with polygamous men: a cross-sectional observational study at a tertiary hospital in Somalia

BackgroundPremature ejaculation (PE) is the most common and prevalent sexual disorder among men. To the best of our knowledge, this is the first study aimed at evaluating the relationship of PE among polygamous men.MethodOver a 1-year period, a cross-sectional observational study was carried out among 202 married men who visited the urology polyclinic due to different clinical conditions and contributed by completing a standardized structured questionnaire regarding their sociodemographic data, as well as sexual and past medical history.ResultsIn our study, the prevalence of PE was 37.1%; half of the monogamous men (50%) complained of PE, while 22% of men with two wives, 20% of men with three wives, and 12% of men with four wives complained of PE (p < 0.0001, 95% CI 0.122–1.920). Seventy percent of erectile dysfunction (ED) patients had PE concurrence (p < 0.0001, 95% CI 0.057–5.543). Regarding frequency of sexual intercourse, 48% of patients who complained of PE performed sexual intercourse less than two times/week, while two-thirds of the participants who did not complain of PE had sexual intercourse two to four times/week (p < 0.0001, 95% CI 0.203–0.568). Among the men who reported ED, 42% had one wife, 21.5% had two wives, 40% had three wives, and 12.5% had four wives (p < 0.029, 95% CI 0.417–0.962).ConclusionsWe report that polygamous men have a lower incidence of premature ejaculation and higher sexual satisfaction than monogamous men. There is a significant association between ED and PE, showing a complex and bidirectional relationship between the two conditions. The new taxonomic entity called loss of control of erection and ejaculation (LCEE) views the two sexual symptoms as deeply interrelated. The study results indicate that a sexual intercourse frequency of two or more times per week significantly lowers the risk of PE.

Premature ejaculation: An investigative study into assumptions, facts and perceptions of patients from the Middle East (PEAP STUDY)

ABSTRACT Objective: To determine the prevalence of premature ejaculation (PE) in Qatar as a representative of the Middle East region and the population perception of normal ejaculation. Subjects and methods: This study was a cross-sectional, observational, non-interventional, epidemiological study, conducted from February 2012 to February 2013. Randomly selected married males were asked to answer two questionnaires in a direct interview. The first questionnaire assessed the PE complaint, the time between ejaculation and intromission (actual intravaginal ejaculatory latency time [IELT-a]), and the perceived normal average time between intromission and ejaculation (IELT-p). The second questionnaire used was the Arabic Index of Premature Ejaculation (AIPE). Results: A total of 3042 subjects were included. The mean (SD) age was 37.09 (9.1) years. The prevalence of PE in Qatar using the self-report and AIPE score was 38.5% and 36.2%, respectively. The median (interquartile range) IELT-a and IELT-p were 5 (3–13.5) and 15 (5–15) min. In the AIPE-confirmed PE group, and according to the AIPE severity classification, the differences in IELT-a and IELT-p between the severity groups were highly significant, with the duration of both IELT-a and ILET-p being higher in AIPE-No-PE and mild-PE groups (P < 0.001 for both). A negative correlation was found between AIPE score and age in the PE group. Conclusion: The prevalence of PE in Qatar is high. PE prevalence was found to increase with age. The IELT and perception of normal IELT were both correlated with the severity of PE.

EARLY EJACULATION

Information on the epidemiology, etiology and treatment of premature ejaculation is reviewed. Evidence of the prevalence of premature ejaculation indicates that subjective concern about rapid ejaculation is a common concern worldwide. The hypotheses regarding the pathogenesis of premature ejaculation include: 1.) that it is a learned model of ejaculation maintained by interpersonal anxiety and 2.) that it is a dysfunctional result of the central or peripheral mechanisms that regulate ejaculatory thresholds and 3.) that it is a normal variant in latency ejaculation. Current evidence-based treatment interventions include behavioral psychotherapy and the use of pharmacological agents, including topical anesthetics and selective serotonin reuptake inhibitors. The purpose of this paper is to review the existing knowledge base on the definition, prevalence, etiology and treatment of premature ejaculation.

Association of sexual behaviours and premature ejaculation

Premature ejaculation (PE) is the most common reported sexual complaint in men. It is believed that PE is associated with sexual behavior such as early sexual experience, novelty of partners or frequencies of intercourse. Therefore, to examine the association of PE and sexual behaviors in men, a case-control study was conducted with a total of 418 clients Subjects were interviewed for general health status, sexual behaviors, IELT and requested to complete the premature ejaculation diagnostic tool (PEDT). DSM-IV-TR criteria were applied for the diagnosis of PE. Those who diagnosed with PE(+) and PEDT score ≥ 11 belonged to the PE group; those diagnosed with PE(-) and PEDT &lt; 11 belonged to the non-PE group. The results indicated that no significant difference was noted regarding demographic features in the 2 groups. Normal men had a more frequent sexual life compared with PE patients (9.71 ± 6.09 and 6.62 ± 5.44 episodes of sexual intercourses per month, respectively with p &lt; 0.001. Subjects who were single or circumcised had higher prevalence of PE than married or uncircumcised men. Multivariable logistic analysis elucidated that circumcision, number of lifetime sexual partners and sexual frequencies were associated factors of PE. In conclusion, PE is a common sexual dysfunction in men. It was found to be significantly associated with circumcision and frequencies of sexual intercourse. Medical history taking of PE patients should include these sexual behavior factors.

Sexual dysfunctions and short-term glucose variability in young men with type 1 diabetes

PurposeErectile dysfunction (ED) and premature ejaculation (PE) are common sexual disorders in people with diabetes. Glucose variability (GV) has been recognized as a predictor of microvascular complications. The aim of this study was to investigate the relationship between glucose variability and sexual dysfunctions in young men with type 1 diabetes.MethodsOne hundred and twelve patients with type 1 diabetes, aged 18–30 years, were enrolled. Patients were divided into two groups according to glucose variability [group 1 (high GV with coefficient of variation ≥ 36%)] and group 2 (low GV with coefficient of variation < 36%)). The presence of sexual dysfunctions was investigated with validated questionnaires.ResultsED and PE prevalence rates in group 1 were 26% and 13%, respectively. Similarly, in group 2, the prevalence of ED was 24%, and the prevalence of PE was 13%. In both groups, no significant associations between sexual dysfunctions and parameters of glucose variability were found. Multiple regression analysis identified age and depression as independent predictors of ED and PE.ConclusionYoung male patients affected by type 1 diabetes with high or low glucose variability show a similar prevalence of sexual dysfunctions. ED is the most common sexual dysfunction in diabetic men. Age and depression were the only independent predictive factors for sexual dysfunctions in this population.

Premature Ejaculation patients and their partners: arriving at a clinical profile for a real optimization of the treatment.

The aim of the study is to extrapolate clinical features of Premature Ejaculation (PE) patients and female partners of men affected with PE, in order to get a profile that can be of assistance for physicians within the dynamics of a couple, one of which is a PE patient. An observational, non-interventional, cross-sectional epidemiological study entitled IPER (Italian Premature Ejaculation Research) was conducted and included two different cohorts of subjects that were randomly sampled from a patient dataset of selected General Practitioners: 1. IPER-M sub-cohort (1.104 subjects) was made of male subjects in which they were then distinguished patients with or without PE based on the score of the PEDT questionnaire; IPER-F sub-cohort (1.109 subjects) was made of female subjects from an independent sample of women (therefore not the partners of the IPER-M males) in which they then distinguished those partners of a male subject with PE or not. In addition to an identical general questionnaire to explore demographic aspects and habits, each subcohort was then evaluated using validated questionnaires. No differences were noted between PE+/PE- patients in terms of alcohol consumption, smoking habits, physical activity nor stress condition in everyday life, employment, socio-economic class and marital status. While the prevalence of PE proportionally increased with age, excluding the 50-59 and 70-80 years decades, in the IPER-M group an overall statistically significant difference for the mean age between the PE+ and PE- groups (p = 0.002) was detected, but without reaching any difference amongst the different age classes in the IPER-F group. The PE+ patients reported a significantly lower frequency rate of sexual intercourse, worse QoL (p = 0.006 and p < 0.0001, respectively), and increased anxiety status (p < 0.0001 for both subgroups). This study shows that, rather than talking with a patient affected by PE it would be advisable to introduce the concept of couple counseling with the person patient and his partner, because it is only through classification of both partners as one couple and a full understanding of their mutual sexual experience that PE treatment can be optimized and its results measured accurately.

EARLY EJACULATION

Information on the epidemiology, etiology and treatment of premature ejaculation is reviewed. Evidence of the prevalence of premature ejaculation indicates that subjective concern about rapid ejaculation is a common concern worldwide. The hypotheses regarding the pathogenesis of premature ejaculation include: 1.) that it is a learned model of ejaculation maintained by interpersonal anxiety and 2.) that it is a dysfunctional result of the central or peripheral mechanisms that regulate ejaculatory thresholds and 3.) that it is a normal variant in latency ejaculation. Current evidence-based treatment interventions include behavioral psychotherapy and the use of pharmacological agents, including topical anesthetics and selective serotonin reuptake inhibitors. The purpose of this paper is to review the existing knowledge base on the definition, prevalence, etiology and treatment of premature ejaculation. American Psychiatric Association (2013).

Premature Ejaculation and Endocrine Disorders: A Literature Review.

Premature ejaculation (PE) is the most common male sexual dysfunction, with 30% of men experiencing PE worldwide. According to the generally accepted classification, there are two types of PE: lifetime PE and acquired PE. Various biological and psychological causes are known to be involved in the etiology of PE. However, due to the incomplete definition and etiopathogenesis of PE, there is no effective treatment. Although clinical and animal studies indicate that hormones play a role in controlling the ejaculation process, the precise endocrine mechanisms are unclear. In addition, little is known about the role of endocrine disorders in PE etiology. However, there is evidence that diabetes mellitus (DM), obesity, metabolic syndrome (MetS), thyroid gland disorders, pituitary gland disorders, and vitamin D deficiency affect the prevalence of PE. Moreover, it has been reported that the prevalence of PE decreases with treatment of these endocrine disorders. In this review, the relationship between PE and DM, MetS, obesity, vitamin D deficiency, and thyroid and pituitary gland disorders is summarized.
