Ten-Year Interval Changes in the Prevalence of Self-Identified Premature Ejaculation and Premature Ejaculation Based on an Estimated Intravaginal Ejaculation Latency Time of <3 Minutes in the General Population: The Korean Internet Sexuality Survey (KISS) 2016

Updating, correcting, and calibrating the narrative about premature ejaculation

INTRODUCTION

The narrative surrounding premature ejaculation (PE) has developed and solidified over the past 25 years. Unfortunately, portions of that narrative are outdated and do not reflect more recent conceptualizations or empirical findings regarding this disorder.

OBJECTIVE

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.

METHOD

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.

RESULTS

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.

CONCLUSION

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.

Impact of infertility duration on male sexual function and mental health

PURPOSE

This study aimed to explore whether infertility duration has an impact on the sexual function and mental health of men from infertile couples.

METHODS

We conducted a case-control study of 558 men from infertile couples, and the participants were divided into four groups based on their infertility duration: group I: ≤ 2 years; group II: 2-5 years; group III: 5-8 years; and group IV: > 8 years. Sexual function and mental disorders were measured using the International Index of Erectile Function-15 (IIEF-15), Premature Ejaculation Diagnostic Tool (PEDT), Generalized Anxiety Disorder scale (GAD-7), and Patient Health Questionnaire (PHQ-9) separately.

RESULTS

As the years of infertility duration increase, the total IIEF-15 score and four domains (sexual desire, orgasmic function, erectile function, and intercourse satisfaction) significantly decrease (p < 0.05). The PEDT score gradually increases significantly (p < 0.05). Increased infertility duration is an independent risk factor for erectile dysfunction and premature ejaculation (p < 0.05). However, increased infertility duration is not a risk factor for depression and anxiety (p > 0.05).

CONCLUSIONS

Our study is the first time to use the infertility duration as an independent variable and group this variable to analyze its impact on the sexual function and mental health of men from infertile couples comprehensively and systematically. The increased infertility duration is an independent risk factor for the occurrence of sexual dysfunction but not for mental disorders. In the process of infertility treatment, sexual health and mental health cannot be ignored, especially for patients with prolonged infertility.

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

Background

Premature 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.

Method

Over 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.

Results

In 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).

Conclusions

We 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 Among Internet Users Living in the Metropolitan Region of São Paulo, Brazil: A Cross-Sectional Comparison Between the Premature Ejaculation Diagnostic Tool (PEDT) and Patient-Reported Latency Time and Perception

Background

Premature ejaculation (PE) prevalence can vary according to different definitions, assessment methods and populational demographics and culture.

Aims

To investigate the differences between men classified as having “probable PE” (PEDT≥11), “possible PE” (PEDT = 9 or 10) or “no PE” (PEDT≤8) according to the Premature Ejaculation Diagnostic Tool (PEDT) criteria in regard to sociodemographic characteristics, and sexual and relational behavior. To assess the agreement of prevalence of PE according to 3 assessment methods: (i) the ejaculation latency time (ELT) according to the participant's memory; (ii) PEDT and (iii) a direct question about the self-perception of ejaculation as being normal, too early (premature) or retarded.

Methods

In this web-based cross-sectional study, men aged ≥ 18 years living in the metropolitan region of São Paulo, Brazil, responded anonymously to an online survey. We used multinomial regression to estimate the association between PE according PEDT criteria and other features and the kappa coefficient to estimate agreement between the assessment methods.

Outcomes

Association between PEDT-PE, sociodemographic characteristics and sexual and relational behaviors; agreement between PEDT, ELT and self-perception of PE.

Results

Obesity, trying to hold back ejaculation, short or nonexistent foreplay and age <30 years were associated with PEDT ≥11. Men who considered that latency was shorter for oral, anal and vaginal sex than for masturbation were more likely to have probable PE according to PEDT. Possible PE (PEDT scores 9/10) was associated with trying to hold back ejaculation and considering time for ejaculation shorter for vaginal sex. There was fair agreement between assessments (kappa 0.39; CI:0.28 –0.42; P < .001).

Conclusion

PE prevalence varies according to instruments and cut-offs used, with fair agreement between them. This finding shows that the methods evaluate different aspects of the EP syndrome and they must be combined to allow the discrimination between the different types of PE and treatments. Clinical approaches should consider the sexual behavior and relationship of the patient and their distress.

The Effect of Pelvic Floor Rehabilitation on Males with Sexual Dysfunction: A Narrative Review

INTRODUCTION

Increasing evidence has suggested that pelvic floor exercises and manual physical therapy may improve premature ejaculation (PE) and erectile dysfunction (ED) in males.

OBJECTIVES

To examine the effects of pelvic floor physical therapy treatment in men suffering from PE and ED.

METHODS

We searched Google Scholar, PubMed, Medline, PEDro databases from inception till January 2020 applying the following keywords: pelvic floor, erectile dysfunction, impotence, physiotherapy, exercises, rehabilitation, and pelvic floor muscle exercises.

RESULTS

The review included 37 papers reporting on PE and ED, of which 5 were randomized controlled trials, 2 meta-analyses, and 4 observational studies. Pelvic floor physical therapy treatment included education and rehabilitation. The rehabilitation part encompassed manual therapy techniques that contribute to the normalization of muscle tone and improvement of muscle relaxation. Moreover, exercises, according to the patients' clinical assessment were presented. Most of the studies reported that by strengthening the pelvic floor muscles (PFMs), ED and PE can be improved if manual physical therapy treatments are combined with PFM training.

CONCLUSIONS

A multifaceted approach should be chosen by physical therapists when evaluating and treating ED and PE and contending with both musculoskeletal dysfunction and behavioral contributions. It is recommended that exercises be monitored and situations involving, that is, hyperactivity/increased tone of the PFMs should be avoided. PFM training is simple, safe, and noninvasive; therefore, it should be a preferred approach in the management of ED and PE. This paper presents narrative reviews with a potential bias that systematic reviews or meta-analyses do not have, however, we strove to be all-encompassing and unbiased. There is a demand for high-quality scientific reviews examining the effectiveness of PFM training, manual therapy, and the rationale of pelvic floor physical therapy, in general, in treating individuals with PE and ED.
