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

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.

The rs6296 polymorphism in the 5-HT1b receptor in Dutch men with lifelong premature ejaculation: a genetic case-control association study

BACKGROUND

Lifelong premature ejaculation (LPE) is a rare sexual condition believed to be caused by genetic neurobiological disorders.

AIM

In this study we sought to evaluate the genetic association between the rs6296 polymorphism of the 5-HT1b receptor and intravaginal ejaculation latency times (IELTs) in men with LPE compared with men in a control group.

METHODS

This study was a prospective observational genetic case-control association study. The LPE definition of the International Society for Sexual Medicine (ISSM) 2013 was used. Patients were recruited in 2005-2009 while attending the department of Neurosexology, HagaZiekenhuis, the Netherlands. We obtained IELTs with the stopwatch method. Polymerase chain reaction (PCR) was used for genotyping rs6296. A randomly selected group of European Caucasian men from the 1000GENOMES project was used as a control group.

OUTCOMES

Study outcomes included results of comparisons of analysis of variance (ANOVA) tests between genotypes and IELTs in study participants, genotypes of cases and controls determined with the chi-square test, and expressions of allelotype- and genotype-specific risks for LPE determined with odds ratios.

RESULTS

In total, 67 men with LPE were included in this study. The geometric mean (SD) IELT was 32.0 (27.4) seconds and was non-normally distributed. Genotype frequencies consisted of 29 (43.3%) GG, 31 (46.3%) GC, and 7(10.4%) CC individuals in the LPE group. Log-transformed IELTs were not statistically significant (per ANOVA tests) in men with GG, GC, or CC genotypes (P = .54). Genotype frequencies consisted of 16 (6.6%) GG; 93 (38.8%) GC, and 131 (54.6%) CC individuals in the control group (n = 240). Significant differences were found when comparing allele (P = 1.02e-17) and genotype (P = 3.22e-16) frequencies in cases and controls using a chi-square test. A statistically significant increased risk for LPE was found for carriers of the G allele (OR 5.62; 95% CI 4.13-9.42). Statistically significant risks were also found for the CG genotype (OR 6.24; 95% CI 2.63-14.77) and the GG genotype (OR 33.92; 95% CI 12.79-89.93).

CLINICAL IMPLICATIONS

By investigating polymorphisms in target genes the neuro-pathophysiology of LPE could be further elaborated, potentially leading to more effective treatment.

STRENGTHS AND LIMITATIONS

This is to our knowledge the first study investigating rs6296 with regard to LPE. By using a strict definition for LPE (ISSM 2013) and using the stopwatch method for measuring IELTs, bias in selection of true LPE patients will be relatively low. This study is limited by a relatively small study population and the lack of IELT data in the control group.

CONCLUSIONS

This study shows a genetic association in rs6296 in men with LPE compared with healthy controls. This result warrants attempted replication in future studies.

Impact of cognitive behavioral therapy on premature ejaculation patients: A prospective, randomized controlled trial protocol

BACKGROUND

Premature ejaculation (PE) is one of the most common male sexual dysfunctions, with a prevalence of about 4%-39% in the Chinese population. Studies have shown that a variety of biological factors can lead to premature ejaculation, such as central nervous system disorders, hypersensitivity of the penis head, and psychological factors. Based on clinical experience, psychological counseling and education of patients and partners should be ranked as the first priority when treating PE. Cognitive behavioral therapy (CBT) addresses emotional, behavioral, and cognitive disorders by altering beliefs and actions. It has also been demonstrated to be clinically useful in treating a number of diseases. The purpose of this trial is to evaluate the efficacy of a mobile-based CBT intervention on patients with PE compared to conventional routine treatment.

METHODS

This study is a prospective randomized controlled trial that will be conducted from May 2023 to Dec 2024 at ten hospitals, primarily including the First Affiliated Hospital of Sun Yat-sen University with an 8-week follow-up. The clinical trial central randomization system will be used to create and implement the specific randomization method. Baseline data of both groups will be measured and collected. The premature ejaculation diagnostic tool (PEDT) and the female sexual distress scale-revised for premature ejaculation (FSDS-R-PE) will be collected on the first day, 28±2 days, and 56±2 days during the intervention period, and the intravaginal ejaculatory latency time (IELT) will be measured in both groups. The Shapiro-Wilk test will be used for normality testing. Pearson correlation analysis will be used for correlation analysis. Differences between groups will be compared using analysis of variance or exact probability calculations.

DISCUSSION

This study will investigate the effect of a mobile-based CBT intervention on patients with PE.

Validity of self-reported male sexual function scales in a young Chinese population: a comparative study with clinician-assisted evaluation

Psychometric scales, commonly used to gauge sexual function, can sometimes be influenced by response biases. In our research from June 2020 to April 2021, we examined the accuracy of self-reported sexual function scales. We invited patients from the Department of Infertility and Sexual Medicine at the Third Affiliated Hospital of Sun Yat-sen University (Guangzhou, China), who have male sexual dysfunction, to participate by filling out a self-reported version of a specific questionnaire. In addition, they went through a clinician-assisted version of this questionnaire, encompassing tools such as the Premature Ejaculation Diagnostic Tool (PEDT), the 6-item International Index of Erectile Function (IIEF-6), the Erection Hardness Scale (EHS), and the Masturbation Erection Index (MEI). Using the clinician-assisted version as a reference, we categorized patients and applied various statistical methods, such as the Chi-square test, intraclass correlation coefficient (ICC), logistic regression, and the Bland-Altman plot, to gauge reliability. In our study with 322 participants, we found that while there were no notable discrepancies in error rates based on our categorization, certain scales showed significant differences in terms of overestimation and underestimation, with the exception of the PEDT. The positive diagnosis rate consistency between the self-reported and clinician-assisted versions was observed. High ICC values between the two versions across the scales were indicative of remarkable reliability. Our findings show that the self-reported versions of tools such as EHS, IIEF-6, MEI, and PEDT are credible and hold clinical reliability. However, employing a dual-diagnosis approach might be more prudent to circumvent potential misdiagnoses.

Management of Male Infertility with Coexisting Sexual Dysfunction: A Consensus Statement and Clinical Recommendations from the Asia-Pacific Society of Sexual Medicine (APSSM) and the Asian Society of Men's Health and Aging (ASMHA)

Male infertility (MI) and male sexual dysfunction (MSD) can often coexist together due to various interplay factors such as psychosexual, sociocultural and relationship dynamics. The presence of each form of MSD can adversely impact male reproduction and treatment strategies will need to be individualized based on patients' factors, local expertise, and geographical socioeconomic status. The Asia Pacific Society of Sexual Medicine (APSSM) and the Asian Society of Men's Health and Aging (ASMHA) aim to provide a consensus statement and practical set of clinical recommendations based on current evidence to guide clinicians in the management of MI and MSD within the Asia-Pacific (AP) region. A comprehensive, narrative review of the literature was performed to identify the various forms of MSD and their association with MI. MEDLINE and EMBASE databases were searched for the following English language articles under the following terms: "low libido", "erectile dysfunction", "ejaculatory dysfunction", "premature ejaculation", "retrograde ejaculation", "delayed ejaculation", "anejaculation", and "orgasmic dysfunction" between January 2001 to June 2022 with emphasis on published guidelines endorsed by various organizations. This APSSM consensus committee panel evaluated and provided evidence-based recommendations on MI and clinically relevant MSD areas using a modified Delphi method by the panel and specific emphasis on locoregional socio-economic-cultural issues relevant to the AP region. While variations exist in treatment strategies for managing MI and MSD due to geographical expertise, locoregional resources, and sociocultural factors, the panel agreed that comprehensive fertility evaluation with a multidisciplinary management approach to each MSD domain is recommended. It is important to address individual MI issues with an emphasis on improving spermatogenesis and facilitating reproductive avenues while at the same time, managing various MSD conditions with evidence-based treatments. All therapeutic options should be discussed and implemented based on the patient's individual needs, beliefs and preferences while incorporating locoregional expertise and available resources.

Association between COVID-19 and sexual health: an umbrella review

PURPOSE

We conducted this umbrella review to review the current evidence on the relationship between COVID-19 and sexual health in both men and women.

METHODS

We conducted searches in Pubmed, Embase, and the Cochrane dataset for meta-analyses that met our pre-set inclusion criteria. We included studies with detailed information investigating the link between COVID-19 and sexual health in men/women. We did not limit the language.

RESULTS

The results of the included studies frequently relied on the Female Sexual Function Index to assess sexual health in women. For men, the International Index of Male Function and hospital diagnoses were commonly used to assess sexual health. Currently, there is conflicting evidence regarding the impact of COVID-19 on sexual health. However, since most studies were observational in nature, additional study designs are necessary to draw definitive conclusions across different contexts.

CONCLUSION

Our findings highlight the importance of sexual health among COVID-19 patients and people affected due to COVID-19. Further critical studies should investigate the mechanism underlying the association between COVID-19 and sexual health.

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.

[Recommendations for the treatment of premature ejaculation]

OBJECTIVES

The Post-University Interdisciplinary Association of Sexology (AIUS) has brought together a panel of experts to develop French recommendations for the management of premature ejaculation.

METHODS

Systematic review of the literature between 01/1995 and 02/2022. Use of the clinical practice guidelines (CPR) method.

RESULTS

We recommend giving all patients with PE psychosexological counseling, and whenever possible combining pharmacotherapies and sexually-focused cognitive-behavioral therapies, involving the partner in the treatment process. Other sexological approaches could be useful. We recommend the use of dapoxetine as first-line, on-demand oral therapy for primary and acquired PE. We recommend the use of lidocaine 150mg/mL/prilocaine 50mg/mL spray as local treatment for primary PE. We suggest the combination of dapoxetine and lidocaine/prilocaine in patients insufficiently improved by monotherapy. In patients who have not responded to treatments with marketing authorisation, we suggest using an off-label SSRI, preferably paroxetine, in the absence of a contraindication. We recommend treating ED before PE in patients with both symptoms. We do not recommend using α-1 blockers or tramadol in patients with PE. We do not recommend routine posthectomy or penile frenulum surgery for PE.

CONCLUSION

These recommendations should contribute to improving the management of PE.

Clinical value of penile sympathetic skin response to assess the efficacy of sertraline in the treatment of patients with sympathetic hyperexcitability in primary premature ejaculation

Background

The pathogenesis of primary premature ejaculation (PPE) is complex, and the pathologic basis may be an overactive sympathetic nervous system.

Aim

To investigate sertraline efficacy in patients with sympathetic hyperexcitability in PPE and clarify the value of penile sympathetic skin response (PSSR) in assessing the efficacy of sertraline for PPE treatment.

Methods

Sixty-three patients with PPE were recruited in the outpatient clinic and asked to take 50 mg of oral sertraline daily for a 4-week treatment period. Changes in intravaginal ejaculation latency time (IELT), Premature Ejaculation Diagnostic Tool, International Index of Erectile Function (IIEF-5), and PSSR latency and wave amplitude were compared before and after treatment.

Outcomes

The principal aim was to determine the relationships among sertraline efficacy, IELT, and PSSR latency and amplitude.

Results

After sertraline treatment, patients with PPE demonstrated a significant decrease in Premature Ejaculation Diagnostic Tool scores (P &lt; .001); a significant increase in IELT, PSSR latency, and wave amplitude (P &lt; .001); and no significant change in International Index of Erectile Function scores (P &gt; .05). Moreover, the latency changes of PSSR were positively correlated with the increment of IELT (r = 0.550, P &lt; .001). In addition, there was some degree of improvement vs pretreatment, although IELT and PSSR latencies were significantly shorter after drug discontinuation when compared with posttreatment (both P &lt; .001).

Clinical Implications

We aimed to find an objective test that accurately reflects the efficacy of treatment for sympathetic hyperexcitability in PPE.

Strengths and Limitations

The strengths include a well-powered study, use of validated instruments, and self-assessment of treatment benefit. The limitations include the single-center design, relatively short-term follow-up, and lack of more comprehensive monitoring between treatment and drug discontinuation.

Conclusion

These findings suggest that sertraline is effective for PPE treatment, that its efficacy can be partially maintained even after drug discontinuation, and that PSSR may be reliable for evaluating treatment success in patients with PPE.

Erectile dysfunction and premature ejaculation: a continuum movens supporting couple sexual dysfunction

PURPOSE

The specific underlying mechanisms supporting the association between erectile dysfunction (ED) and premature ejaculation (PE) are still not completely clarified. To summarize and discuss all available data supporting the relationship between PE and ED.

METHODS

A comprehensive narrative review was performed. In addition, to better clarify the specific factors underlining ED and PE, a meta-analytic approach of the selected evidence was also performed. In particular, the meta-analytic method was selected in order to minimize possible sources of bias derived from a personal interpretation of the data.

RESULTS

Current data confirm the close association between ED and PE and the bidirectional nature of their relationship. In particular, PE was associated with a fourfold increased risk of ED independently of the definition used. In addition, the risk increased in older patients and in those with lower education, and it was associated with higher anxiety and depressive symptoms. Conversely, ED-related PE was characterized by lower associations with organic parameters such as diabetes mellitus, arterial hypertension, dyslipidemia and with smoking habit. Finally, when ED was defined according to the International Index of Erectile Function questionnaire, the presence of a stable relationship increased the risk.

CONCLUSIONS

ED and PE should be considered in a dimensional prospective way considering the possibility that both clinical entities can overlap and influence each. Correctly recognizing the underlying factors and sexual complaint can help the clinician in deciding the more appropriate diagnostic and therapeutic work-up.

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.

The Tenuous Role of Distress in the Diagnosis of Premature Ejaculation: A Narrative Review

BACKGROUND

Unlike the other 2 criteria for diagnosing premature ejaculation (PE), namely lack of ejaculatory control and short ejaculation latency (EL), the role of bother/distress has received only minimal consideration and investigation.

AIM

The specific aim was to determine both why distress is included in the PE diagnosis and whether such inclusion is advantageous to achieving better diagnostic outcomes. To this end, the review explored the historical and theoretical underpinnings of the inclusion of "bother/ distress" in the diagnosis of PE, with reference to the larger role that distress has played in the diagnosis of mental disorders, in an attempt to understand the utility (or lack thereof) of this construct in making a PE diagnosis.

METHODS

We reviewed the role of bother/distress across current professional definitions for PE and then expanded this discussion to include the role of distress in other sexual dysfunctions. We then included a brief historical perspective regarding the role that distress has played in the diagnosis of PE. This discussion is followed by a deeper look at 2 nosological systems, namely DSM and ICD, to allow perspective on the inclusion of the bother/distress construct in the diagnosis of mental and behavioral disorders, including the assumptions/arguments put forward to include or exclude bother/distress as an important criterion underlying various professional assumptions.

OUTCOME

Determination of the value and/or need of including bother/distress as a necessary criterion for the diagnosis of PE.

RESULTS

Based on the research literature, bother/distress does not appear to be as critical for a PE diagnosis as either the lack of ejaculatory control or short EL. It is the weakest of the differences among men with and without PE, and recent evidence suggests that its inclusion is generally redundant with the severity of the 2 other criteria for PE, ejaculatory control and EL.

CLINICAL TRANSLATION

Bother/distress appears to serve little purpose in the diagnosis of PE yet its assessment may be important for the treatment strategy and for assessing treatment effectiveness.

STRENGTHS AND LIMITATIONS

This review did not provide a critical analysis of the literature regarding the role of bother/distress in PE, but rather focused on its potential value in understanding and diagnosing PE.

CONCLUSION

Although bother/distress appears to add little to the improvement of accuracy for a PE diagnosis, understanding and assessing the man's or couple's experience of distress has important implications for the treatment strategy and focus, as well as for assessing treatment success.

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.

Correlations between Personality Traits, Patient-Reported Outcome, and Chronic Prostatitis Symptoms in Men with Different Premature Ejaculation Syndromes

Although the personality traits (PT), patient-reported outcome (PRO), and chronic prostatitis (CP) symptoms in premature ejaculation (PE) have been evaluated, there was no study to assess their correlations in men with different PE syndromes. The purpose of this study was to assess the correlations between the PT, PRO, and CP symptoms in men with different PE syndromes. Between January 2019 and January 2021, a cross-sectional field study was conducted in our andrology clinic. Men with the complaints of PE were divided into lifelong PE (LPE), acquired PE (APE), variable PE (VPE), and subjective PE (SPE). All subjects were required to complete a verbal questionnaire with the PRO, National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), and Temperament and Character Inventory (TCI-R). Finally, 479 men with the complaints of PE and 365 without the complaints of PE were enrolled. The incidence of PE syndromes in PE complaint group was as follows: LPE 16.70%, APE 48.85%, VPE 11.27%, and SPE 23.17%. Mean ages in PE complaint group were 42.53 ± 12.25 years. In the PE complaint group, the novelty seeking (NS) scores were strongest correlated with the personal distress and quality of life (QOL). The harm avoidance (HA) scores were strongest correlated with the severity of PE and pain syndromes. The self-transcendence (ST) scores were strongest correlated with the satisfaction with sexual intercourse and QOL. In addition, strongest association between the total scores of NIH-CPSI and the NS or ST scores was also found in the APE group. The HA scores were also strongest correlated with the total scores of NIH-CPSI in SPE. Strongest association between the total scores of NIH-CPSI and the NS/TI or ST/CI scores was also found in the APE group. The HA/TI scores were also strongest correlated with the total scores of NIH-CPSI in SPE.

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.

Premature Ejaculation Measures During Partnered Sex and Masturbation: What These Findings Tell Us About the Nature and Rigidity of Premature Ejaculation

Men with premature ejaculation (PE) during partnered sex (as defined by poor ejaculatory control) show significantly reduced PE symptomology during masturbation, but the reasons for this disparity are not clear. This study investigated the other two PE-related diagnostic criteria, namely ejaculatory latency (EL) and bother/distress, in order to explore possible explanations for this disparity between types of sexual activity. Specifically, 1,447 men with either normal or poor ejaculatory control were compared on EL parameters, bother/distress, and sexual satisfaction/pleasure during both partnered sex and masturbation. Results indicated that men with PE reported longer ELs during masturbation than partnered sex, in contrast with men without PE who reported shorter ELs during masturbation. Bother/distress was lower for both groups during masturbation, but bother/distress in men with PE during masturbation was comparable to that of men without PE during partnered sex. Minimal difference in these patterns was found across lifelong and acquired PE subtypes, whereas men with PE with comorbid erectile dysfunction appeared to represent a distinct group. These findings have implications for PE management or treatment as well as for the overall conceptualization of PE as a pathophysiological condition.

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.

Sexual Dysfunction in Men and Women with Diabetes: A Reflection of their Complications?

BACKGROUND

Diabetes mellitus (DM), one of the worldwide leading causes of death, is associated with a plethora of micro- and macro-vascular complications which should be carefully investigated and, in case, treated in order to improve quality of life and reduce the risk of premature mortality.

OBJECTIVE

The study aimed to investigate and report current evidence with regard to the association between sexual dysfunction and diabetes.

METHODS

A detailed analysis of current literature has been performed on PubMed and Scholar in order to retrieve the most relevant findings pertaining to the study topic.

RESULTS

Female and male sexual dysfunction often occurs in diabetes; while cardiovascular complications are clearly involved, psychosexological factors, endocrine complications, and endothelial dysfunction all contribute to the pathogenesis of sexual dysfunctions. Psychological symptoms are seldom investigated, yet they should not be overlooked by the clinician; in fact, an interplay between sexual dysfunctions and depressive symptoms has been reported, and beneficial effects in both conditions might be obtained by adequate psychological support. Sexual dysfunctions can also act as early biomarkers of cardiovascular disease, a phenomenon frequently reported in men, in which erectile dysfunction predicts the development of coronary artery disease. Additionally, drug therapies can act in both directions, with treatments for diabetes possibly improving male sexual function and exerting beneficial effects for cardiovascular health being reported for pro-erectile drugs.

CONCLUSION

Sexual dysfunctions often occur in men and women with diabetes. Investigating micro- and macro-vascular complications might not be enough to prevent the development or worsening of any sexual dysfunction; endocrine and psychological assessments are therefore needed to provide the best chances for adequate treatment.

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 upregulation of tryptophan hydroxylase-2 expression is important for premature ejaculation treatment with the selective serotonin reuptake inhibitor

BACKGROUND

Although there was some evidence to suggest that the serotonergic system in the brain played an important role in premature ejaculation (PE), tryptophan hydroxylase-2 (TPH2) is considered to be the key enzyme for the synthesis of 5-hydroxytryptamine (5-HT) and few studies have reported that brain TPH2 is involved in the regulation of ejaculation.

OBJECTIVES

This study aimed to investigate whether changes in brain TPH2 levels were associated with PE and to explore the effects of acute administration of dapoxetine on TPH2 expression in the brain of rats with rapid ejaculation.

MATERIALS AND METHODS

Based on the ejaculation frequency, the male rats were split into three groups: "rapid," "normal," and "sluggish" ejaculators. The level of 5-HT in the brain was determined by an enzyme-linked immunosorbent assay. TPH2 expression was detected by western blot analysis and immunohistochemistry.

RESULTS

The results showed that the concentration of 5-HT and the expression of TPH2 in rapid rats were the lowest, while those in sluggish rats were the highest. Correlation analysis also indicated the level of TPH2 was positively correlated with ejaculation latency (r = 0.8633, p < 0.0001) and negatively correlated with ejaculation frequency (r = -0.874, p < 0.001). In addition, dapoxetine acute administration to rapid rats resulted in upregulation of TPH2 expression in the brain.

DISCUSSION

There was an important link between the level of TPH2 and the change of ejaculation behaviors. Decreased expression of TPH2 in relevant brain regions will lead to rapid ejaculation. Moreover, the effect of dapoxetine on prolonging ejaculation may be due to the upregulation of TPH2 expression.

CONCLUSION

We found the correlation between the level of TPH2 in the brain and PE. The findings in this study will open up a novel way for future research in PE therapy.

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.

The Sexual Long COVID (SLC): Erectile Dysfunction as a Biomarker of Systemic Complications for COVID-19 Long Haulers

Introduction

Long term complications of COVID-19, the disease caused by the SARS-CoV-2, involve many organ systems, dramatically worsening the quality of life, and finally contributing to impaired physical functioning. Despite the presence of well-identified pathogenetic mechanisms, the effect of “Long COVID” on sexual health has been only marginally addressed.

Objectives

To provide coverage of the current literature on long COVID, its epidemiology, pathophysiology, and relevance for erectile function. Methods. Comprehensive review of literature pertaining to the epidemiology and pathophysiology of long COVID, and its relevance for erectile function.

Results

Symptoms of long COVID are highly prevalent and involve almost all systems of the human body, with a plethora of clinical manifestations which range from minor nuisances to life-threatening conditions. “Brain fog” and fatigue are the most common complaints, although other neuropsychiatric complications, including sensory dysfunctions, anxiety, depression, and cerebrovascular events have also been reported. The respiratory and cardiovascular systems are also affected, with dyspnea, pulmonary fibrosis, endothelial dysfunction, and myocarditis occurring in some COVID long haulers. A subset of patients might develop endocrine manifestations, including onset of diabetes, thyroid dysfunction, and hypogonadism. Overall, long COVID features many complications which can impair erectile function by multiple pathogenetic mechanisms, and which could require tailored treatment: (i) careful investigation and management from the sexual medicine expert are therefore much needed, (ii) and future research on this topic is warranted.

Conclusion

in COVID-19 long haulers, several complications can adversely affect erectile function which, upon future tailored studies, could be used as biomarker for the severity of the long COVID disease and for its follow-up.

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.

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.

Facing Counterfeit Medications in Sexual Medicine. A Systematic Scoping Review on Social Strategies and Technological Solutions

Introduction

The counterfeit phenomenon is a largely under-reported issue, with potentially large burden for healthcare. The market for counterfeit drugs used in sexual medicine, most notably type 5 phosphodiesterase inhibitors (PDE5i), is rapidly growing.

Aims

To report the health risks associated with the use of counterfeit medications, the reasons driving their use, and the strategies enacted to contain this phenomenon.

Methods

A systematic scoping review of the literature regarding counterfeit PDE5i was carried between January and June 2021, then updated in August 2021.

Main Outcome Measure

We primarily aimed to clarify the main drivers for counterfeit PDE5i use, the health risks associated, and the currently available strategies to fight counterfeiters.

Results

One hundred thirty-one records were considered for the present scoping review. Production of fake PDE5i is highly lucrative and the lacking awareness of the potential health risks makes it a largely exploitable market by counterfeiters. Adulteration with other drugs, microbial contamination and unreliable dosages make counterfeit medications a cause of worry also outside of the sexual medicine scope. Several laboratory techniques have been devised to identify and quantify the presence of other compounds in counterfeit medications. Strategies aimed at improving awareness, providing antitampering packaging and producing non-falsifiable products, such as the orodispersible formulations, are also described.

Clinical implications

Improving our understanding of the PDE5i counterfeit phenomenon can be helpful to promote awareness of this issue and to improve patient care.

Strengths & Limitations

Despite the systematic approach, few clinical studies were retrieved, and data concerning the prevalence of counterfeit PDE5i use is not available on a global scale.

Conclusion

The counterfeit phenomenon is a steadily growing issue, with PDE5i being the most counterfeited medication with potentially large harmful effects on unaware consumers.

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.

Tele-medicine versus face-to-face consultation in Endocrine Outpatients Clinic during COVID-19 outbreak: a single-center experience during the lockdown period

CONTEXT

The COVID-19 outbreak in Italy is the major concern of Public Health in 2020: measures of containment were progressively expanded, limiting Outpatients' visit.

OBJECTIVE

We have developed and applied an emergency plan, tailored for Outpatients with endocrine diseases.

DESIGN

Cross-sectional study from March to May 2020.

SETTING

Referral University-Hospital center.

PATIENTS

1262 patients in 8 weeks.

INTERVENTIONS

The emergency plan is based upon the endocrine triage, the stay-safe procedures and the tele-Endo. During endocrine triage every patient was contacted by phone to assess health status and define if the visit will be performed face-to-face (F2F) or by tele-Medicine (tele-Endo). In case of F2F, targeted stay-safe procedures have been adopted. Tele-Endo, performed by phone and email, is dedicated to COVID-19-infected patients, to elderly or frail people, or to those with a stable disease.

MAIN OUTCOME MEASURE

To assess efficacy of the emergency plan to continue the follow-up of Outpatients.

RESULTS

The number of visits cancelled after endocrine triage (9%) is lower than that cancelled independently by the patients (37%, p < 0.001); the latter reduced from 47 to 19% during the weeks of lockdown (p = 0.032). 86% of patients contacted by endocrine-triage received a clinical response (F2F and tele-Endo visits). F2F visit was offered especially to young patients; tele-Endo was applied to 63% of geriatric patients (p < 0.001), visits' outcome was similar between young and aged patients.

CONCLUSIONS

The emergency plan respects the WHO recommendations to limit viral spread and is useful to continue follow-up for outpatients with endocrine diseases.

Male Sexual Health and Sexual Behaviors during the First National COVID-19 Lockdown in a Western Country: A Real-Life, Web-Based Study

Restriction measures enacted during the COVID-19 pandemic had severe effects on male sexual and reproductive health. We aimed to investigate the real-life impact and perception of sexual function in 2020 in Italy, as the first Western country experiencing a national lockdown by measuring relative search volume for keywords pertaining to sexual health and behaviors provided by Google Trends and sales data for pro-erectile treatments. No significant change was observed for erectile dysfunction and premature ejaculation. Interest towards most phosphodiesterase type 5 inhibitors decreased significantly during lockdown (e.g., sildenafil, p = 0.0002; tadalafil p = 0.0016), then reverted to pre-lockdown levels (e.g., sildenafil, p < 0.0001; tadalafil p < 0.0001), mirroring a concomitant sales decrement (p = 0.0292). A subsequent recovery to previous levels at the end of the social confinement was also found (e.g., after vs. before lockdown, sildenafil, p = 0.8459; tadalafil p = 0.1166). During lockdown, interest towards pornography significantly increased during restrictions (p = 0.0053) and remained high (after vs. before lockdown, p = 0.0004), whereas interest towards paid and casual sex declined (p = 0.0015 and p = 0.049, respectively), then reverted to previous levels (after vs. before lockdown, p = 0.3969 and 0.8373, respectively). During the first Italian lockdown, we observed a transient but measurable decrease of sexual health-seeking behaviors and changes in sexual behaviors, with unknown impact for sexual medicine and public health.

Sperm cryopreservation during the SARS-CoV-2 pandemic

PURPOSE

Sperm cryopreservation is fundamental in the management of patients undergoing gonadotoxic treatments. Concerns have risen in relation to SARS-CoV-2 and its potential for testicular involvement, since SARS-CoV-2-positive cryopreserved samples may have unknown effects on fertilization and embryo safety. This study therefore aimed to analyze the safety of sperm cryopreservation for cancer patients after the onset of the pandemic in Italy, through assessment of the risk of SARS-CoV-2 exposure and viral RNA testing of semen samples.

METHODS

We recruited 10 cancer patients (mean age 30.5 ± 9.6 years) referred to our Sperm Bank during the Italian lockdown (from March 11th to May 4th 2020) who had not undergone a nasopharyngeal swab for SARS-CoV-2 testing. Patients were administered a questionnaire on their exposure to COVID-19, and semen samples were taken. Before cryopreservation, SARS-CoV-2 RNA was extracted from a 150 µl aliquot of seminal fluid in toto using QIAamp viral RNA kit (Qiagen) and amplified by a real time RT PCR system (RealStar SARS-CoV2 RT PCR, Altona Diagnostics) targeting the E and S genes.

RESULTS

The questionnaire and medical interview revealed that all patients were asymptomatic and had had no previous contact with COVID-19 infected patients. All semen samples were negative for SARS-CoV-2 RNA.

CONCLUSION

This preliminary assessment suggests that a thorough evaluation (especially in the setting of a multidisciplinary team) and molecular confirmation of the absence of SARS-CoV-2 in seminal fluid from asymptomatic cancer patients may assist in ensuring the safety of sperm cryopreservation.

Impact of the SARS-CoV2 pandemic dissemination on the management of neuroendocrine neoplasia in Italy: a report from the Italian Association for Neuroendocrine Tumors (Itanet)

INTRODUCTION

The organization of the healthcare system has significantly changed after the recent COVID-19 outbreak, with a negative impact on the management of oncological patients. The present survey reports data collected by the Italian Association for Neuroendocrine Tumors on the management of patients with neuroendocrine neoplasia (NEN) during the pandemic dissemination.

METHODS

A survey with 57 questions was sent to NEN-dedicated Italian centers regarding the management of patients in the period March 9, 2020, to May 9, 2020 RESULTS: The main modification in the centers' activity consisted of decreases in newly diagnosed NEN patients (- 76.8%), decreases in performed surgical procedures (- 58%), delays to starting peptide receptor radionuclide therapy (45.5%), postponed/canceled follow-up examinations (26%), and canceled multidisciplinary teams' activity (20.8%). A low proportion of centers (< 10%) reported having to withdraw systemic anti-tumor medical treatment due to concerns about the pandemic situation, whereas PRRT was withdrawn from no patients.

CONCLUSION

Although the COVID-19 outbreak induced the centers to reduce some important activities in the management of NEN patients, the Italian network was able to provide continuity in care without withdrawing anti-tumor treatment for the majority of patients.

Gender susceptibility to COVID-19: a review of the putative role of sex hormones and X chromosome

BACKGROUND

The recent emergence of COVID-19 poses a global health emergency. One of the most frequently reported data is sex-related severity and mortality: according to the last available analysis on 239,709 patients in Italy, lethality is 17.7% in men and 10.8% in women, with 59% of total deaths being men. Interestingly, the infection rate is lower in males than in females, with 45.8% and 54.2% of positive cases, respectively, suggesting that gender-related factor may worsen disease evolution. A tentative hypothesis to explain these findings is the role of angiotensin-converting enzyme 2 (ACE2) and serine protease TMPRSS2 involved in viral infection.

PURPOSE

In this review, we summarize the available evidence pointing to gender-related differences in ACE2 and TMPRSS2 expression, from both genetic and endocrine points of view.

RESULTS

Altogether, available evidence points toward two not-mutually exclusive mechanisms in gender susceptibility to COVID-19 by sex hormonal regulation of ACE2 and TMPRSS2. On one hand, ACE2 expression could be increased in women, either by estrogens or constitutively by X chromosome inactivation escape or by reduced methylation, providing a larger reservoir of ACE2 to maintain the fundamental equilibrium of RAS regulatory axis. On the other, low levels of androgens in women may keep at low levels TMPRSS2 expression, representing a further protective factor for the development of COVID-19 infection, despite the increased expression of ACE2, which represents the Trojan horse for SARS-CoV-2 entry.

CONCLUSIONS

Both mechanisms consistently point to the role of sex hormones and sex chromosomes in the differential severity and lethality of COVID-19 in men and women.

What we have to know about corticosteroids use during Sars-Cov-2 infection

PURPOSE

Glucocorticoids (GCs), alone or associated to other drugs, were widely used in the management of patients affected by severe acute respiratory syndrome caused by SARS-CoV-2 infection, during the recent COVID-19 outbreak. This review summarizes the available data on HPA axis impairment in GC-treated SARS-CoV-2 patients, focusing on the risk of adrenal insufficiency and on potential drug interactions during concomitant treatments.

METHODS

Literature on the impact of GCs therapy on HPA axis and on the consequences of coadministration of GCs and other drugs in SARS-CoV-2 patients has been reviewed.

RESULTS

GC treatment can cause symptoms of hypercortisolism, especially in patients with individual hypersensibility, or hypoadrenalism after drug withdrawal, due to hypothalamic-pituitary-adrenal (HPA) axis suppression, with consequences in terms of increased morbidity and mortality risk. On the other hand, in SARS-CoV-2-infected patient's cortisol secretion could be insufficient also due to critical illness-related corticosteroid insufficiency (CIRCI). In addition, in this clinical context, the co-administration of antiretroviral drugs and corticosteroids may trigger drug-drug interaction and enhance the exposure to the latter ones, metabolized through the CYP450 CYP3A pathway, severely impacting on HPA axis.

CONCLUSION

Physicians involved in the management of patients affected by COVID-19 should be aware of the need of an appropriate GC dose tapering, and of potential interaction of GCs with antiviral therapy and drugs used to treat associated co-morbidities.

Effect of the COVID-19 pandemic and social distancing measures on the sexual functions of women treated for vaginismus (genitopelvic pain/penetration disorder)

Introduction and hypothesis

Female sexual function is influenced by the emotional and hormonal state. COVID-19 has been the major global health crisis of our time with high psychosocial impact. Vaginismus is a form of female sexual dysfunction and a subset of genitopelvic pain/penetration disorder in which any form of vaginal penetration is painful or impossible. Our aim was to evaluate the effect of the COVID-19 pandemic on sexual function of women treated for vaginismus.

Materials and methods

All women treated using dilators between 2018–2019 were included. Data obtained 3 months after comfortable penetration and during the pandemic via telephone interview were compared. The Female Sexual Function Index (FSFI), Golombok-Rust Inventory of Sexual Satisfaction (GRISS), and Beck Depression Inventory (BDI) were used to evaluate sexual function and depression. Frequency of sexual intercourse and pain was compared using a visual analogue scale.

Results

Seventy-seven women were included. Mean duration of treatment and number of treatment sessions were 3.5 ± 2.6 months and 4.2 ± 2.6, respectively. There were significant improvements in the FSFI desire, arousal, orgasm, and pain subscales and total score and in the GRISS infrequency, noncommunication, avoidance, non-sensuality, and vaginismus subscales and total score during the pandemic. The GRISS dissatisfaction and anorgasmia subscales and BDI score significantly worsened. Mean frequency of sexual intercourse was 2.3 ± 1.8/week and did not change significantly. Pain scores decreased during the pandemic (2.7 ± 2.8) compared to post-treatment (6.2 ± 2.9).

Conclusion

Although frequency of sexual intercourse was not affected and pain scores and FSFI total and subscale scores improved, satisfaction and orgasm were adversely affected, which may be attributed to increased stress and anxiety during the pandemic.

Application of micronised acellular dermal matrix for primary premature ejaculation: A preliminary study

This study aimed to explore the efficacy of injection of micronised acellular dermal matrix (MADM) particles for treating primary premature ejaculation. This study was a prospective single-arm clinical trial. Thirty patients who met the surgical indications were enrolled. MADM particles, mixed in platelet-rich plasma, were injected into Buck's fascia to spread over the dorsal penile nerve, suppress the influx of nerve impulses and, thus, reduce penis sensitivity. We evaluated the changes according to intravaginal ejaculation latency time using a stopwatch and a premature ejaculation diagnostic tool. Meanwhile, we also recorded sexual partner satisfaction and adverse events. All patients recovered well after surgery with no complications such as infections or allergies. The mean intravaginal ejaculation latency time before surgery was 0.72 ± 0.28 min, compared with 2.41 ± 0.54 min, 2.64 ± 0.41 min, 2.79 ± 0.25 min and 2.89 ± 0.35 min at, respectively, 4, 8, 16 and 20 weeks after surgery. The premature ejaculation diagnostic values and sexual partner satisfaction had significantly improved after treatment. Injection of MADM particles is an effective, safe and simple method for treating premature ejaculation.

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

Premature ejaculation (PE) and poor ejaculatory control are multidimensional sexual symptoms estimated to affect almost one-third of men, severely impairing the overall quality of life of patients and their partners. However, patients who do not completely fulfil the definition criteria for PE rarely receive a diagnosis or adequate treatment, with the risk of subsequent progression from initial, subclinical symptoms to clinically overt PE, frequently with other sexual comorbidities. Thus, the current definitions of PE warrant review, in order to consider and propose a new taxonomy encompassing other unaddressed, crucial clinical aspects of PE. These newly proposed criteria include the recommendation for a primary screening for erectile dysfunction (ED), as PE and ED can be comorbid in up to 50% of patients but have never before been considered as a unified clinical entity. In order to facilitate clinical practice and improve clinical management of men with PE and comorbid conditions, we propose and define the new taxonomic clinical entities of subclinical PE (SPE) and loss of control of erection and ejaculation (LCEE). Application of these diagnoses to men who meet the criteria for SPE and/or LCEE, but not the overt conditions, could improve access to treatment for these patients and reduce progression to the more serious clinical disorder.

Addressing male sexual and reproductive health in the wake of COVID-19 outbreak

PURPOSE

The COVID-19 pandemic, caused by the SARS-CoV-2, represents an unprecedented challenge for healthcare. COVID-19 features a state of hyperinflammation resulting in a "cytokine storm", which leads to severe complications, such as the development of micro-thrombosis and disseminated intravascular coagulation (DIC). Despite isolation measures, the number of affected patients is growing daily: as of June 12th, over 7.5 million cases have been confirmed worldwide, with more than 420,000 global deaths. Over 3.5 million patients have recovered from COVID-19; although this number is increasing by the day, great attention should be directed towards the possible long-term outcomes of the disease. Despite being a trivial matter for patients in intensive care units (ICUs), erectile dysfunction (ED) is a likely consequence of COVID-19 for survivors, and considering the high transmissibility of the infection and the higher contagion rates among elderly men, a worrying phenomenon for a large part of affected patients.

METHODS

A literature research on the possible mechanisms involved in the development of ED in COVID-19 survivors was performed.

RESULTS

Endothelial dysfunction, subclinical hypogonadism, psychological distress and impaired pulmonary hemodynamics all contribute to the potential onset of ED. Additionally, COVID-19 might exacerbate cardiovascular conditions; therefore, further increasing the risk of ED. Testicular function in COVID-19 patients requires careful investigation for the unclear association with testosterone deficiency and the possible consequences for reproductive health. Treatment with phosphodiesterase-5 (PDE5) inhibitors might be beneficial for both COVID-19 and ED.

CONCLUSION

COVID-19 survivors might develop sexual and reproductive health issues. Andrological assessment and tailored treatments should be considered in the follow-up.

Validity of Erectile Function Assessment Questionnaires in Premature Ejaculation Patients: A Comparative Study Between the Abridged Forms of the International Index of Erectile Function and Proposal for Optimal Cutoff Redefinition

BACKGROUND

Patients with premature ejaculation (PE) are often diagnosed as having a comorbid erectile dysfunction (ED). When evaluating erectile function in PE patients with the popular International Index of Erectile Function-5 (IIEF-5, or Sexual Health Inventory for Men [SHIM]), question #5 (Q5) about sexual satisfaction in the intercourse often lowers the total score of the questionnaire, giving false-positive results for the presence of ED.

AIM

We aimed to compare SHIM with the other abridged form of IIEF, which is IIEF-EF, and to discriminate which tool has the best diagnostic accuracy in the evaluation of erectile function in PE patients.

METHODS

The study was conducted from March 2019 to January 2020. A total of 189 heterosexual males with lifelong PE (117, 61.9%) or acquired PE (72, 38.1%) were included. They all compiled Premature Ejaculation Diagnostic Tool, IIEF-15, SHIM, and IIEF-EF and underwent a full clinical examination to evaluate their erectile function.

OUTCOMES

The scores of the 2 erectile function assessment questionnaires (SHIM and IIEF-EF) were compared in terms of their sensitivity and specificity in the diagnosis of ED in PE patients.

RESULTS

In terms of diagnosing ED in PE patients, the sensitivity of SHIM is 100% while the specificity is only 36%; meanwhile, the sensitivity of IIEF-EF is 100% but specificity is 77.2%. Further analysis demonstrates that decreasing cutoff of SHIM to 17.5 would provide an increased specificity of 82.5%, while sensitivity would lower to 96.0%. However, the highest area under the curve (0.966 vs 0.941) is given by the IIEF-EF with 100% sensitivity and 80.7% specificity at the cutoff of 24.5, which is one point lower than the usual cutoff value of 25.5.

CLINICAL IMPLICATIONS

Our study suggests that when evaluating erection function in PE patients, the cutoff of both SHIM and IIEF-EF should be amended.

STRENGTHS & LIMITATIONS

We proposed the solution for the bias of erectile function assessment in PE patients. However, other trials are needed to further validate in larger cohorts of PE patients.

CONCLUSION

We suggest that the cutoff of SHIM and IIEF-EF should be amended (SHIM at 17.5 and IIEF-EF at 24.5, respectively) when assessing erectile function among PE population.

Diagnostic Criteria for Premature Ejaculation: Clarifying the Role of “Ejaculatory Control” and “Bother/Distress”

“Ejaculatory control” and “bother/distress” are key criteria for diagnosing men with premature ejaculation (PE), yet compared with ejaculatory latency (EL), these constructs have received only minimal attention. In addition, they have not been characterized in men having different sexual orientations or subtypes of PE. This study aimed to characterize relationships among ejaculatory control, bother/distress, and EL; to assess differences across men having different sexual orientations, PE status, and PE subtypes (i.e., lifelong vs. acquired); and to determine the importance of ejaculatory control to men’s sexual partners. In total, 1071 men and sexual partners of men rated their ejaculatory control and bother/distress and estimated their EL; these measures were compared across sexual orientation, PE status, PE subtype, and male and female partners of men. Results revealed a monotonic though slightly curvilinear relationship between ejaculatory control and bother/distress. These PE criteria differed significantly between PE and non-PE men, to a lesser extent between gay and straight men, and not at all between men having lifelong vs. acquired PE. Female and male partners of men affirmed the importance of ejaculatory control during partnered sex, indicating lack of control as a potential reason for ending a relationship.

Safety and efficacy of traditional Chinese medicine, Qiaoshao formula, combined with dapoxetine in the treatment of premature ejaculation: An open-label, real-life, retrospective multicentre study in Chinese men

To evaluate the safety and efficacy of Chinese medicine, Qiaoshao formula combined with dapoxetine was used for the treatment of premature ejaculation in a real-life setting. Nine hundred and five males diagnosed with premature ejaculation were reviewed in this retrospective cohort study. We divided the patients into two groups: dapoxetine alone and Qiaoshao formula combined with dapoxetine according to actual interventions provided to patients in clinics. The perceived intravaginal ejaculation latency time and the premature ejaculation profile measures markedly improved in both groups. However, in men with severe premature ejaculation (baseline perceived intravaginal ejaculation latency time <1 min) and those with baseline age ≤30 years, the perceived intravaginal ejaculation latency time was slightly but significantly longer with combined therapy than with dapoxetine alone (p < .05). Therefore, combined therapy involving the Qiaoshao formula and dapoxetine proved to safe as well as effective for treating premature ejaculation while prolonging the perceived intravaginal ejaculation latency time, which significantly improved the overall satisfaction of the patient and likely that of the couple.
