Redefining a sexual medicine paradigm: subclinical premature ejaculation as a new taxonomic entity

Efficacy and safety of PDE5 inhibitors in middle-aged and old patients with and without hypogonadism

PURPOSE

Although several reviews have evaluated the use of PDE5 inhibitors (PDE5i) for treating erectile dysfunction (ED), their specific use in middle-aged and old patients has not been fully evaluated. Given that elderly patients with ED often have a complex combination of systemic and sexual health risk factors, the safety and efficacy of PDE5i in such a context are hereby reviewed.

MATERIALS AND METHODS

A thorough examination of existing literature has been conducted on PubMed.

RESULTS

PDE5i has good safety and efficacy, but the situation is more complex for patients with hypogonadism than those with normal testosterone levels, with reduced responsiveness to PDE5i. In this case, combination therapy with testosterone is recommended, safe and effective.

CONCLUSIONS

Eliminating or reducing reversible risk factors and controlling or slowing the development of irreversible factors is an important foundation for using PDE5i to treat ED in all patients, especially middle-aged and elderly ones.

Repeated sexual intercourse as a coping strategy for men with premature ejaculation

BACKGROUND

Patients with premature ejaculation (PE) are often concerned and distressed about their sexual performance. Hence, they may be more willing to exploit their refractory period to employ sexual coping strategies in order to improve their unsatisfactory sexual intercourse compared with patients without PE.

AIM

The study sought to verify the sexual coping strategies of patients with PE in the daily sexual activities.

METHODS

We included both patients with PE and individuals without PE and analyzed their sexual behaviors and attitudes by means of detailed interviews and questionnaires.

OUTCOMES

The main outcomes were perceived intravaginal ejaculatory latency time recording, Premature Ejaculation Diagnostic Tool score, and sexual frequency, attitudes, and behavior log.

RESULTS

A total of 182 young patients with PE (age 31.2 ± 6.2 years) and 92 individuals without PE (age 30.7 ± 5.1 years) were included in the study. A total of 53.3% of patients with PE vs 17.4% of individuals without PE reported engaging in multiple sexual intercourse sessions within a single day in the past 4 weeks. PE patients who engaged in multiple intercourse sessions displayed better performance during the second attempt but performed poorly compared with individuals without PE. Scores for the first attempt in PE vs second attempt in individuals with PE vs without PE were the following: intravaginal ejaculatory latency time, 2.4 ± 1.6 vs 4.8 ± 5.7 vs 9.9 ± 9.4 (P < .001); Premature Ejaculation Diagnostic Tool, 14.9 ± 3.1 vs 12.7 ± 4.8 vs 5.2 ± 2.5 (P < .001); satisfaction, 2.9 ± 1.0 vs 3.1 ± 0.8 vs 3.7 ± 1.4 (P < .001). A total of 57.1% of patients held a negative attitude toward precoital masturbation, for reasons such as a reduced sexual desire (21.2%), the belief that masturbation is harmful (17.6%), concerns about erectile function (15.7%), fatigue (9.8%), and other mixed reasons (35.3%).

CLINICAL IMPLICATIONS

Engaging in multiple intercourse sessions within a day is more common among the young PE population, and using precoital masturbation as a coping strategy is not universally applicable among patients with PE.

STRENGTHS AND LIMITATIONS

This is the first study to explore symptom-coping strategies in patients with PE compared with individuals without PE. However, the conclusions cannot be generalized to the entire male population.

CONCLUSION

Patients with PE, compared with individuals without PE, are more inclined to engage in multiple sexual intercourse sessions within a single sexual session, likely in an attempt to compensate for their first unsatisfactory sexual encounter. Moreover, the majority of patients with PE here studied hold a negative attitude toward using precoital masturbation as a coping strategy for symptoms.

From couplepause to doublepause: the impact of midlife physical, psychological, and social changes on the sexual life of aging couples

INTRODUCTION

Midlife men and women are facing frequent sexual problems that affect not only individuals' sexual health but also the sexual health of aging couples.

OBJECTIVES

To review the main sexual life challenges faced by midlife couples, to present the concepts of couplepause and doublepause as 2 new paradigms to address the sexual health needs of aging couples, and to discuss key aspects in couple-focused care.

METHODS

An online meeting attended by 5 European experts in sexual health was carried out in June 2023 to discuss the topic. The conversation centered on their clinical experience and expert opinion. Additionally, the indexed literature was reviewed to endorse and complement the expert opinions obtained in the aforementioned meeting.

RESULTS

Midlife men and women face physical, psychological, and sociocultural changes that affect their sexual activity. These changes may be experienced differently between genders. Both members of a couple may experience age-related changes concurrently or in an unsynchronized manner affecting their sexual health. Communication, sharing expectations, defining sexual dynamics, and couple goals are determinant for the sexual health of a midlife couple. Couplepause and doublepause are 2 new complementary paradigms that effectively address the sexual health needs of aging couples as a unit, considering physical, psychological, cultural, social, and dyadic-related factors. Couple-centered strategies should promote open communication about couple intimacy issues, understanding the diverse expectations according to gender and orientation, communication styles, and goals. The following are identified as crucial aspects to promote couple-focused care: education and training of health care professionals, the provision of information to aging couples, physician involvement in addressing sexual problems, the need for collaboration across medical specialties, and the development of effective tools and strategies.

CONCLUSIONS

The sexual problems of aging couples should be managed following couple-centered strategies that effectively address their sexual health needs as a couple.

Pornography and sexual function in the post-pandemic period: a narrative review from psychological, psychiatric, and sexological perspectives

The COVID-19 pandemic and lockdowns had significant impacts on sexual functioning and behavior. Partnered sexual activity decreased overall, while solo sex activities such as masturbation and pornography consumption increased exponentially. Given the ongoing debate about the effects of pornography on sexual function, it was prudent to consider how the increase in porn consumption during the pandemic might have impacted sexual function in the post-pandemic period. Results indicated that despite the increased rates of use during lockdowns, there remains no evidence supporting the relationship between sexual dysfunction and porn use during and following the pandemic period. On the contrary, pornography consumption and solo sex activities offered an alternative to conventional sexual behavior during a highly stressful period and were found to have positive effects of relieving psychosocial stress otherwise induced by the pandemic. Specifically, those who maintained an active sexual life experienced less anxiety and depression, and greater relational health than those who were not sexually active. It is important to consider factors including frequency, context, and type of consumption when analyzing the impact of pornography on sexual function. While excessive use can have negative effects, moderate use can be a natural and healthy part of life.

Altered reward processing in patients with lifelong premature ejaculation

Given that sexual behavior is usually pleasurable and highly rewarding, it is surprising that there is as yet no known research to empirically assess how premature ejaculation (PE) patients respond to the rewarding aspect of sexual behavior. This study was designed to address this issue by evaluating how these men respond to the anticipation and hedonic experience of sexual rewards in comparison to non-sexual rewards. Thirty lifelong PE patients and thirty healthy controls (HCs) performed the incentive delay task manipulating both erotic and monetary rewards. Compared to HCs, lifelong PE patients exhibited significantly faster RTs to erotic cues than to monetary cues during reward anticipation. Meanwhile, hedonic experience ratings after obtaining the actual reward showed that erotic rewards were rated as more pleasant than monetary rewards only by lifelong PE patients, which was driven by a decreased sensitivity to experienced monetary rewards in lifelong PE patients compared to HCs. These findings indicate the existence of dysfunctional reward processing in lifelong PE patients, which is characterized by increased incentive motivation elicited by sexual cues and reduced hedonic impact of nonsexual rewards. This study may offer an insightful clue regarding how PE is related to the abnormal regulation of the rewarding aspect of sexual behavior.

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.

Acupuncture for premature ejaculation: a systematic review and meta-analysis

Background

Although acupuncture is widely used to treat premature ejaculation (PE), its effectiveness remains highly controversial.

Aim

To evaluate the efficacy and safety of acupuncture on PE.

Methods

According to the relevant keywords, 11 major English and Chinese databases were searched for randomized controlled trials (RCTs) of acupuncture alone or in combination with other treatments for PE. The quality of evidence across studies was assessed by the GRADEpro tool.

Outcomes

Study outcome measures included the intravaginal ejaculation latency time (IELT), the Premature Ejaculation Diagnostic Tool (PEDT), the Chinese Index of Premature Ejaculation-5 (CIPE-5), treatment success rate, and adverse events.

Results

Seven trials were included in this review for a total of 603 participants. A low quality of evidence suggests that it is not possible to determine whether acupuncture, as compared with a selective serotonin reuptake inhibitor, has an advantage in improving the IELT (standardized mean difference [SMD], -1.75; 95% CI, -6.12 to 2.63; P = .43, I² = 98%), PEDT scores (SMD, 0.32; 95% CI, -0.68 to 1.32; P = .53, I² = 85%), and treatment success rate (risk ratio, 0.69; 95% CI, 0.41-1.14; P = .15). However, participants receiving acupuncture had a lower CIPE-5 (SMD, -1.06; 95% CI, -1.68 to -0.44; P < .01). As compared with sham acupuncture, acupuncture significantly improved the IELT (SMD, 1.47; 95% CI, 1.01-1.92; P < .01, I² = 0%) and PEDT scores (SMD, -1.23; 95% CI, -1.78 to -0.67; P < .01, I² = 37%). When compared with other treatments alone, a combined treatment with acupuncture can significantly improve the IELT (SMD, 7.06; 95% CI, 2.53-11.59; P < .01, I² = 97%), CIPE-5 (SMD, 0.84; 95% CI, 0.45-1.22; P < .01, I² = 0%), and treatment success rate (SMD, 1.60; 95% CI, 1.18-2.16; P < .01, I² = 53).

Clinical Implications

The results suggest a significant effect of acupuncture in the treatment of certain important indicators of PE; however, this finding needs to be treated with caution because of the quality of the RCTs included.

Strengths and Limitations

Comprehensive inclusion of available RCTs has been performed. However, limitations include a low number of studies and a lack of detailed information to allow subgroup analysis.

Conclusion

The present systematic review and meta-analysis show that acupuncture has a significant effect on several subjective PE parameters, such as improving the feeling of control over ejaculation and distress, particularly when used in an integrated way. However, due to the low quality of evidence, acupuncture still needs larger well-designed RCTs to be confirmed.

The Italian Society of Andrology and Sexual Medicine (SIAMS), along with ten other Italian Scientific Societies, guidelines on the diagnosis and management of erectile dysfunction

PURPOSE

Erectile dysfunction (ED) is one of the most prevalent male sexual dysfunctions. ED has been in the past mistakenly considered a purely psycho-sexological symptom by patients and doctors. However, an ever-growing body of evidence supporting the role of several organic factors in the pathophysiological mechanisms underlying ED has been recognized.

METHODS

The Italian Society of Andrology and Sexual Medicine (SIAMS) commissioned an expert task force involving several other National Societies to provide an updated guideline on the diagnosis and management of ED. Derived recommendations were based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system.

RESULTS

Several evidence-based statements were released providing the necessary up-to-date guidance in the context of ED with organic and psychosexual comorbidities. Many of them were related to incorrect lifestyle habits suggesting how to associate pharmacotherapies and counseling, in a couple-centered approach. Having the oral therapy with phosphodiesterase type 5 inhibitors as the gold standard along with several other medical and surgical therapies, new therapeutic or controversial options were also discussed.

CONCLUSIONS

These are the first guidelines based on a multidisciplinary approach that involves the most important Societies related to the field of sexual medicine. This fruitful discussion allowed for a general agreement on several recommendations and suggestions to be reached, which can support all stakeholders in improving couple sexual satisfaction and overall general health.

Clinical Safety of a Pharmaceutical Formulation Containing an Extract of Acmella oleracea (L.) in Patients With Premature Ejaculation: A Pilot Study

Acmella oleracea (L.) R. K. Jansen (Asteraceae) is a plant species widely used in traditional Amazonian medicine to treat sexual dysfunction. The use of this plant has gained popularity because of its sensory properties, such as a tingling sensation. In this study on patients with premature ejaculation, we evaluated the clinical action of a nano-formulation containing an ethanolic extract of A. oleracea inflorescences. Major constituents in the extracts were identified based on gas chromatographic analysis. Participants used a spray preparation based on the A. oleracea extract for 12 weeks, during which they were instructed to apply the product 5 min prior to sexual intercourse. To assess therapeutic efficacy, participants were required to record the mean intravaginal latency time for ejaculation (IELT). During the period of spray treatment, the nano-formulation of A. oleracea increased participant IELT values (M = 293 s) compared with the baseline values (193 s). This nano-formulation reported clinical action in patients with premature ejaculation. It is accordingly considered to have potential application as a therapeutic alternative with benefits for both patients and their partners. Given the small number of participants in this study, further multicenter studies involving a larger number of participants are needed to confirm these observations.

Translation, adaptation, and clinical validation of the Premature Ejaculation Diagnostic Tool in Spanish (Colombia)

Background

Premature ejaculation is the most prevalent form of sexual dysfunction in men. The Premature Ejaculation Diagnostic Tool (PEDT) is an instrument used to evaluate premature ejaculation. It offers adequate psychometric properties and good reliability.

Aim

To adapt and validate a Colombian version of the PEDT in Colombian clinical and nonclinical samples.

Methods

Two samples were used in this study. The first was made up of 1110 men who were recruited to evaluate validity and reliability. Their ages ranged from 19 to 65 years (mean ± SD, 39.71 ± 12.53). The second sample included 123 men (66.7%) who did not meet diagnostic criteria for premature ejaculation per the International Statistical Classification of Diseases and Related Health Problems (ICD-10), while 33.3% met ICD-10 criteria for this dysfunction. Their ages ranged from 18 to 65 years (34.19 ± 12.65). Scores were used to calculate the cutoff.

Outcomes

A translated and adapted version of the PEDT was developed specifically for Colombia. All participants completed the Colombian version of the PEDT, a sociodemographic questionnaire, the Colombian version of the Massachusetts General Hospital-Sexual Functioning Questionnaire, and a semistructured interview based on the ICD-10.

Results

The results showed adequate psychometric properties and satisfactory internal consistency and confirmed the 1-dimensional factorization of the scale. According to ICD-10 criteria, the study also confirmed significant differences between participants who self-reported premature ejaculation and those who did not. In addition, it showed adequate evidence of convergent validity, with a moderate correlation with sexual functioning scores. As a result, the cutoff point was set to 10.5, with an area under the curve of 96.8%. Therefore, a score ≥11 points suggested the presence of premature ejaculation.

Clinical Translation

The current Colombian version of the PEDT is a useful instrument that determines the presence of premature ejaculation that is compatible with ICD-10 criteria.

Strengths and Limitations

The Colombian version of the PEDT presents evidence of reliability and validity, a confirmed 1-dimensional factorization, and a cutoff point for Hispanic populations. More in-depth evaluation of the diagnosis of premature ejaculation is required, and further research among other Spanish-speaking countries and sexual minorities is recommended.

Conclusion

The Colombian version of the PEDT is a psychometric adequacy tool for evaluating and diagnosing premature ejaculation, following the ICD-10 criteria.

The Role of the "Anti-Inflammatory" Couple for the Management of Hyperuricemia With Deposition

INTRODUCTION

Gout is the most prevalent inflammatory crystal arthropathy worldwide and is a chronic disease requiring strict, lifelong adherence to drug therapy and healthy lifestyles. Gout has a heavy burden on the patient's sexual health, owing to the associated inflammatory status, long-term complications, and chronic pain; however, the effects of gout also extend to the partner's sexual health.

AIMS

We aimed to investigate how the presence of a partner could influence the complex interaction between risk factors for sexual dysfunctions in gout in order to define novel strategies to improve sexual health and disease management.

METHODS

Clinical and experimental data on the role of the couple in chronic diseases, as well as on the association between gout and sexual health, were searched through Pubmed.

MAIN OUTCOME MEASURES

Evidence from studies describing how the presence of a couple and leveraging sexual health can improve management and clinical outcomes for chronic diseases.

RESULTS

Treatment adherence can improve the sexual health of gout patients and their partners; likewise, by leveraging sexual health, it would be possible to promote better health-seeking behaviors, ultimately improving gout management.

CLINICAL IMPLICATIONS

Promoting awareness of the sexual health relevance of gout can potentially be a pivotal strategy to improve disease management and prevent the progression of sexual dysfunctions from subclinical to overt forms.

STRENGTHS AND LIMITATIONS

Identifying a bidirectional association between sexual health and disease management paves the way for improved disease control and can potentially prevent the development of sexual dysfunctions in couples affected by gout. However, the relevance of the couple has not been adequately addressed in gout management, and most evidence comes from other chronic diseases.

CONCLUSION

Improving gout management results in better sexual health, and vice-versa promoting better sexual health can improve disease control for gout. The presence of a partner improves the behavioral well-being of gout patients, with beneficial effects on both sexual health and gout management. Sansone A, Reisman Y, Meto S, et al.

Does Bother/Distress Contribute to the Diagnosis of Premature Ejaculation?

Introduction

The role of bother/distress in the diagnosis of premature ejaculation (PE) has received minimal investigation compared with the 2 other diagnostic criteria, ejaculatory control and ejaculatory latency (EL).

Aim

This study assessed (i) the added variance explained by bother/distress to the diagnostic accuracy of PE and (ii) determined its overall contribution to a PE diagnosis.

Methods

The 3 diagnostic criteria for PE were assessed in 2,589 men (mean age = 38.2 years, SD = 13.5) in order to determine the contribution of each factor to a dysfunctional diagnosis. A series of regression and discriminant analyses were used to assess the value of bother/distress in explaining ejaculatory control and in predicting accuracy of PE group status. Commonality analysis was used to determine the relative contribution of each of these factors to the diagnosis of PE.

Main Outcome Measure

The major outcome was the quantified contribution of “bother/distress” to a PE diagnosis.

Results

Bother/distress accounted for about 3–4% of the variation in ejaculatory control and added only minimally to the prediction accuracy of PE group status (no, probable, definite PE). Commonality analysis indicated that bother/distress comprised about 3.6% of the unique explained variation in the PE diagnosis, compared with ejaculatory control and EL which contributed 54.5% and 26.7%, respectively. Common variance among factors contributed the remaining 15.5% to the PE diagnosis.

Clinical Translation

Bother/distress contributes least to the determination of a PE diagnosis. Its contribution is largely redundant with the unique and combined contributions of ejaculatory control and EL.

Strengths and Limitations

Using a well-powered and multivariate analysis, this study parsed out the relative contributions of the 3 diagnostic criteria to a PE diagnosis. The study is limited by its use of estimated EL, a single item assessment of bother/distress, and the lack of differentiation of PE subtypes, lifelong and acquired.

Conclusion

Bother/distress contributes minimally to the PE diagnosis, yet its assessment may be key to understanding the experiences of the patient/couple and to developing an effective treatment strategy.

Validation of holding time, a novel tool to assess control over ejaculation in males: A pilot study

Premature ejaculation (PE) is considered as a disorder of perceived loss of ejaculatory control. However, we cannot objectively estimate ejaculatory control due to the absence of an objective tool to measure it. Hence, we designed a pilot study to validate holding time (HoT), a novel objective tool, hypothesized by us, to measure ejaculatory control in men. The construct validity of this tool to differentiate premature ejaculators from normal ejaculators was also assessed in our sample. The study sample had 10 healthy, sexually active normal ejaculators, and 10 premature ejaculators, who volunteered to participate in the study conducted from May 2020 to April 2021. The mean HoT in normal ejaculators was 120.2 ± 31.7 s and the same in premature ejaculators was 32.9 ± 12.9 s. Both the normal (r = 0.983) as well as premature ejaculators (r = 0.839) had good test-retest reliability. The construct validity of HoT to diagnose PE was good with 90% sensitivity, 91% specificity, 63.8% positive predictive value, and 98.1% negative predictive value to diagnose PE when compared with diagnosis by a standard tool. It could be concluded that HoT successfully measured ejaculatory control in men and differentiated normal ejaculators from the premature ejaculators in the sample studied.

A Prospectively Validated Nomogram for Predicting the Risk of PHQ-9 Score ≥15 in Patients With Erectile Dysfunction: A Multi-Center Study

Background

Although erectile dysfunction (ED) often occurs simultaneously with depression, not all patients with ED suffer major depression (MD), with a PHQ-9 score ≥15 indicating MD. Because the PHQ-9 questionnaire includes phrases such as “I think I am a loser” and “I want to commit suicide,” the psychological burdens of ED patients are likely to increase inevitably after using the PHQ-9, which, in turn, may affect ED therapeutic effects. Accordingly, we endeavored to develop a nomogram to predict individual risk of PHQ-9 score ≥15 in these patients.

Methods

The data of 1,142 patients with ED diagnosed in Xijing Hospital and Northwest Women and Children's Hospital from January 2017 to May 2020 were analyzed. While the Least Absolute Shrinkage and Selection Operator regression was employed to screen PHQ-9 score ≥15 related risk factors, multivariate logistic regression analysis was performed to verify these factors and construct the nomogram. The training cohort and an independent cohort that comprised 877 prospectively enrolled patients were used to demonstrate the efficacy of the nomogram.

Results

The IIEF-5 score, PEDT score, physical pain score, frequent urination, and feeling of endless urination were found to be independent factors of PHQ-9 score ≥15 in patients with ED. The nomogram developed by these five factors showed good calibration and discrimination in internal and external validation, with a predictive accuracy of 0.757 and 0.722, respectively. The sensitivity and specificity of the nomogram in the training cohort were 0.86 and 0.52, respectively. Besides, the sensitivity and specificity of the nomogram in the validation cohort were 0.73 and 0.62, respectively. Moreover, based on the nomogram, the sample was divided into low-risk and high-risk groups.

Conclusion

This study established a nomogram to predict individual risk of PHQ-9 score ≥15 in patients with ED. It is deemed that the nomogram may be employed initially to avoid those with a low risk of MD completing questionnaires unnecessarily.

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

Introduction

The 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.

Aim

To 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.

Methods

Gay 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.

Outcomes

Comparison of ejaculatory control, EL, and bother/distress across gay and straight men, as well as across different types of sexual activities.

Results

A 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 (z_U = -3.35, P < .001) and lower distress (z_U = 3.68, P < .001) relative to straight men, but longer ELs and lower distress were also associated with anal sex.

Clinical Translation

Clinicians 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 Limitations

Although 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.

Conclusions

Irrespective 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.

Off-label Uses of Selective Serotonin Reuptake Inhibitors (SSRIs)

Psychiatric drugs have primacy for off-label prescribing. Among those, selective serotonin reuptake inhibitors (SSRIs) are highly versatile and, therefore, widely prescribed. Moreover, they are commonly considered as having a better safety profile compared to other antidepressants. Thus, when it comes to off-label prescribing, SSRIs rank among the top positions. In this review, we present the state of the art of off-label applications of selective serotonin reuptake inhibitors, ranging from migraine prophylaxis to SARS-CoV-2 antiviral properties. Research on SSRIs provided significant evidence in the treatment of premature ejaculation, both with the on-label dapoxetine 30 mg and the off-label paroxetine 20 mg. However, other than a serotoninergic syndrome, serious conditions like increased bleeding rates, hyponatremia, hepatoxicity, and post-SSRIs sexual dysfunctions, are consistently more prominent when using such compounds. These insidious side effects might be frequently underestimated during common clinical practice, especially by nonpsychiatrists. Thus, some points must be addressed when using SSRIs. Among these, a psychiatric evaluation before every administration that falls outside the regulatory agencies-approved guidelines has to be considered mandatory. For these reasons, we aim with the present article to identify the risks of inappropriate uses and to advocate the need to actively boost research encouraging future clinical trials on this topic.

Reasons and treatment strategy for discontinuation of dapoxetine treatment in premature ejaculation patients in China: A retrospective observational study

To assess dapoxetine discontinuation rates and the reasons for discontinuation in Chinese men with premature ejaculation (PE). Information on 906 PE outpatients was obtained from the hospital information system (HIS) in 2019. Of these, 150 patients were chosen. We analysed the dapoxetine discontinuation rate and the reasons for discontinuation over a 12-week follow-up period. The mean age of all patients was 33.6 years (range = 18-55), the mean PE duration was 12.36 ± 9.45 months. The 5-item International Index of Erectile Function (IIEF-5) score was 21.51 ± 3.80. A total of 37.3% of all the patients remained on the treatment until the 12th week. The cumulative discontinuation rates at the 4th, 8th and 12th weeks were 12%, 41.3% and 62.7%, respectively. The discontinuation rates for all the patients in weeks 0-4, weeks 4-8 and weeks 8-12 were 19.1%, 46.8% and 34.0%, respectively. After 4 weeks, the discontinuation rates dropped sharply. The reasons for patients' discontinuation were as follows: overexpectation of efficacy (30.9%), relapsing after drug withdrawal (26.6%), high cost (25.5%), side effects (9.6%), fear of drug addiction (4.3%), failure of follow-up (2.1%) and choosing other treatments (1.1%). The dapoxetine treatment discontinuation rate was very high. The main reasons for discontinuation were overexpectation of efficacy and high cost.

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

INTRODUCTION

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

OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSION

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

Poor Sleep Quality is an Independent Risk Factor for Acquired Premature Ejaculation

PURPOSE

To determine the role of poor sleep quality as a risk factor for acquired premature ejaculation (APE) after considering the various risk factors, such as ages, lower urinary tract symptoms (LUTS), anxiety, depression, and erectile dysfunction.

METHODS

This study presents a multivariate analysis to identify risk factors for PE, including the covariate of age, International Prostate Symptom Score (IPSS), General Anxiety Disorder-7 (GAD-7) score, Patient Health Questionnaire-9 (PHQ-9) score, International Index of Erectile Function (IIEF) score, and Pittsburgh Sleep Quality Index (PSQI). Acquired PE was defined as self-reported intravaginal ejaculation latency time ≤3 minutes, and poor sleep quality was diagnosed using the Pittsburgh Sleep Quality Index tool.

RESULTS

A total of 349 men were enrolled in the study after completing the questionnaires and the medical history survey. Among 349 men, 203 individuals (58.17%) suffered from acquired PE. The IIEF-5 score, IPSS, GAD-7 score, PHQ-9 score, and PSQI score of the population with PE were significantly different from the non-PE group. Further multivariate analysis showed that erectile dysfunction, depression, severe prostatitis-like symptoms, and poor sleep quality were high-risk factors of APE. Additionally, our study showed that premature ejaculation diagnostic tool (PEDT) score was associated with IPSS/GAD-7/PHQ-9/PSQI scores positively and associated with IIEF-5 scores negatively. The stratified analysis of sleep quality showed that APE patients with different sleep qualities have different prevalence rates of anxiety, depression, prostatitis-like symptoms, and erectile function.

CONCLUSION

In general, sleep quality may be a potential risk factor for patients with acquired premature ejaculation. Our research revealed the impact of sleep quality on premature ejaculation and provided new viewpoints for further understanding and perfecting the pathogenesis of premature ejaculation.

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.

The masturbatory premature ejaculation diagnostic tool (MPEDT): A novel psychometric tool to evaluate premature ejaculation during masturbation

BACKGROUND

Premature ejaculation (PE) is a highly prevalent male sexual dysfunction. Its current definition, together with the most used diagnostic tools, does not include nonvaginal sexual intercourse such as anal sex, self-masturbation and/or partnered-masturbation, and other forms of sexual stimulation. However, diagnostic psychometry currently available is exclusively evaluating PE in the vaginal coitus.

OBJECTIVES

To validate a new tool, the masturbatory premature ejaculation diagnostic tool (MPEDT), by assessing the control over ejaculation and its psychological effects during self-masturbation, rather than heterosexual vaginal intercourse.

MATERIALS AND METHODS

We studied 135 male patients aging from 18 to 40 years seeking medical care for PE in the Infertility and Sexual Medicine Department from June to September 2020. All the participants were asked to fill the premature ejaculation diagnostic tool PEDT and MPEDT questionnaires to estimate the PE symptoms during, respectively, intercourse and self-masturbation. The reliability/validity, the factor analysis of the tool, and the diagnostic sensitivity/specificity of MPEDT were calculated.

RESULTS

The overall Cronbach alpha was 0.884. In our adjusted model, both root mean square error of approximation (RMSEA) and standardized root mean square residual (SRMR) were lower than 0.08, while goodness of fit index, adjusted goodness of fit index, non-normed fit index (NNFI), and comparative fit index (CFI) were higher than 0.9. The area under the ROC curve (AUC) is 0.943 ± 0.015. The results suggest MPEDT points being ≤5 as "normal," ≥7 as "PE during self-masturbation," and 6 as "suspected PE," with the sensitivity of 91.9% and specificity of 88.1%.

DISCUSSION

An efficient diagnostic psychometric tool is needed for the individuals who, based on the impaired control over ejaculation during self-masturbation, may also suffer from PE during partnered intercourse. MPEDT is able to evaluate the existence of PE symptoms not necessarily during heterosexual intercourse but rather during self-masturbation, possibly aiding to the diagnosis, as well as planning and follow-up of a prompt therapeutical strategy.

CONCLUSION

MPEDT could be considered a new, objective, and reliable diagnostic tool for the evaluation of the existence of PE symptoms.

Serum concentrations of dihydrotestosterone are associated with symptoms of hypogonadism in biochemically eugonadal men

PURPOSE

Symptoms of hypogonadism are often reported by subjects with normal serum testosterone (T) levels. We aimed to assess the association between clinical symptoms in andrological outpatients and sex steroids levels.

METHODS

This is a retrospective cross-sectional cohort study in an Academic clinic and research unit. International Index of Erectile Function (IIEF, EF domain) and Aging Males Symptoms scale (AMS) questionnaires were completed by 635 and 574 men, respectively (mean age: 47.3 ± 13.9 and 47.4 ± 13.8 years, p = 0.829), free of interfering medications with complaints possibly related to hypogonadism.

RESULTS

Serum total/free T as well as dihydro-T (DHT) was associated with IIEF-EF and AMS scores in the overall population using univariate analyses. Multivariate approaches revealed DHT concentrations in subjects with normal T levels (n = 416, Total T > 12 nmol/L) to be significant predictors of AMS scores. A 0.1 nmol/l serum DHT increase within the eugonadal range was associated with a 4.67% decrease in odds of having worse symptoms (p = 0.011). In men with biochemical hypogonadism (Total T < 12 nmol/L), total and free T rather than DHT were associated with AMS results. This association was not found for IIEF-EF scores. Indirect effects of age and BMI were seen for relations with hormone concentrations but not questionnaire scores.

CONCLUSION

DHT can be associated with symptoms of hypogonadism in biochemically eugonadal men. Serum DHT measurement might be helpful once the diagnosis of hypogonadism has been ruled out but should not be routinely included in the primary diagnostic process.

Thalamocortical Dysconnectivity In Lifelong Premature Ejaculation: A Functional MRI Study

OBJECTIVES

To detect seed-based functional connectivity (FC) between various cortical sub-regions and the thalamus in lifelong premature ejaculation (LPE) patients and explore whether specific thalamocortical networks are significantly altered in PE patients compared to healthy controls (HCs) METHODS: Fifty non-medicated LPE patients and 40 age-matched HCs underwent a resting-state functional MRI. FC was adopted to identify specific thalamocortical connectivity between the thalamus and 6 cortical regions of interest (i.e., the motor cortex/supplementary motor, the prefrontal cortex, the temporal lobe, the posterior parietal cortex, the somatosensory cortex and the occipital lobe). In LPE patients, regression analysis was subsequently conducted to assess relationships of thalamocortical connectivity with the Premature Ejaculation Diagnostic Tool (PEDT) score and the Intravaginal Ejaculatory Latency Time (IELT).

RESULTS

LPE patients had significantly decreased FC between the motor cortex and bilateral ventral thalamus, between the prefrontal cortex and left dorsomedial thalamus, as well as between the temporal cortex and bilateral ventromedial thalamus. In LPE patients, PEDT score was significantly positively associated with the thalamus-posterior parietal cortex FC, and negatively associated with the thalamus-temporal cortex FC, while IELT was positively associated with the thalamus-temporal cortex and thalamus-motor cortex FC.

CONCLUSION

These results enrich the imaging evidence for the understanding of the neurobiological mechanisms and/or consequences of LPE.

Sexual Response Differs during Partnered Sex and Masturbation in Men With and Without Sexual Dysfunction: Implications for Treatment

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.

The Lost Penis Syndrome: A New Clinical Entity in Sexual Medicine

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.

The Inferto-Sex Syndrome (ISS): sexual dysfunction in fertility care setting and assisted reproduction

PURPOSE

Infertility represents a peculiar social burden affecting more than 15% of couples, provoking it a real threat to the general quality of life and to the sexual health. The medicalization (diagnosis, therapy and follow up) of the lack of fertility is frequently a challenge in term of personal and couple's involvement. In particular, while the Assisted Reproductive Technology (ART) has allowed many infertile couples to achieve pregnancy, the therapeutic process faced by the couple bears a strong psychological stress that can affect the couple's quality of life, relationship and sexuality. Despite infertility affects both female and male sexual health, only recently the interest in the effects of ART on the couple's sexuality has grown, especially for women.

METHODS

A literature research on the sexual dysfunction in fertility care and particularly in ART setting was performed.

RESULTS

Literature largely found that intimacy and sexuality appear specifically impaired by intrusiveness of treatments and medical prescriptions. Moreover, there is a close relationship between emotional, psychological and sexual aspects, which can be integrated in the new concept of Inferto-Sex Syndrome (ISS) that can impair the ART treatment outcomes. Evidence demonstrates that the assessment of sexual function is necessary in couples undergoing diagnosis of infertility and ART.

CONCLUSION

A close relationship between infertility and sexuality, both in the female and male partners, was detected. ART treatments may heavily impact on the couple's psychosexual health. A couple-centred program for the integrated management of psychological and sexual dysfunction should be considered in the context of ART programs.

Management of premature ejaculation: a clinical guideline from the Italian Society of Andrology and Sexual Medicine (SIAMS)

Premature ejaculation (PE) is the most prevalent male sexual dysfunction, and the most recently defined. PE is often mistakenly considered a purely psychosexological symptom by patients: the lacking awareness in regards to the pathophysiology and treatments often lead to resignation from the patients' side, making PE the most underdiagnosed sexual complaint. However, an ever-growing body of evidence supporting several organic factors has been developed in the last decades and several definitions have been suggested to encompass all defining features of PE. In the present document by the Italian Society of Andrology and Sexual Medicine (SIAMS), we propose 33 recommendations concerning the definition, pathophysiology, treatment and management of PE aimed to improve patient care. These evidence-based clinical guidelines provide the necessary up-to-date guidance in the context of PE secondary to organic and psychosexological conditions, such as prostate inflammation, endocrine disorders, and other sexual dysfunctions, and suggest how to associate pharmacotherapies and cognitive-behavioral therapy in a couple-centered approach. New therapeutic options, as well as combination and off-label treatments, are also described.

"Mask up to keep it up": Preliminary evidence of the association between erectile dysfunction and COVID-19

Background

Erectile dysfunction (ED), as the hallmark of endothelial dysfunction, could be a short‐ or long‐term complication of COVID‐19. Additionally, being ED a clinical marker and predictor of non‐communicable chronic diseases, particularly cardiovascular, subjects with ED could potentially have a higher risk of contracting COVID‐19.

Objectives

To investigate the prevalence of ED among subjects with a reported diagnosis of COVID‐19 and to measure the association of COVID‐19 and ED.

Materials and methods

We reviewed data from the Sex@COVID online survey (performed between April 7 and May 4, 2020, in Italy) to retrieve a sample of Italian male sexually active subjects with reported SARS‐CoV‐2 infection. A matching sample of COVID‐19‐negative male sexually active subjects was also retrieved using propensity score matching in a 3:1 ratio. The survey used different standardized psychometric tools to measure effects of lockdown and social distancing on the intrapsychic, relational, and sexual health of Italian subjects.

Results

One hundred subjects were included in the analysis (25 COVID‐positive; 75 COVID‐negative). The prevalence of ED, measured with the Sexual Health Inventory for Men, was significantly higher in the COVID+ group (28% vs. 9.33%; p = 0.027). Logistic regression models confirmed a significant effect of COVID‐19 on the development of ED, independently of other variables affecting erectile function, such as psychological status, age, and BMI [OR 5.66, 95% CI: 1.50–24.01]. Likewise, subjects with ED were more likely to have COVID‐19, once corrected for age and BMI [OR 5.27, 95% CI: 1.49–20.09].

Discussion and conclusion

On top of well‐described pathophysiological mechanisms, there is preliminary evidence in a real‐life population of ED as a risk factor of developing COVID‐19 and possibly occurring as a consequence of COVID‐19. Universal vaccination against the COVID‐19 and the personal protective equipment could possibly have the added benefit of preventing sexual dysfunctions.
