Psychological and sexological assessment of patients with chronic prostatitis.

PURPOSE: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is characterized by a multiform clinical presentation requiring a differentiated treatment based on different phenotypes including the psychosocial and sexual domains. The aim of this study was assessing the complex correlations between somatic, psychological, and sexual symptoms of CP/CPPS patients. MATERIALS AND METHODS: We performed a cross-sectional study on patients attending a Prostatitis Clinic. Patients were administered the following questionnaires: National Institutes of Health- Chronic Prostatitis Symptom Index (NIH-CPSI), International Prostate Symptom Score (IPSS), International Index of Erectile Function (IIEF), Premature Ejaculation Diagnostic Tool (PEDT), Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder 7-item (GAD-7), Oxford Happiness Questionnaire (OHQ), and Temperament Evaluation of Memphis, Pisa, Paris and San Diego Autoquestionnaire (TEMPS-A). RESULTS: Linear regression analyses show highly significant correlations between scores of the NIH-CPSI and the scores of the GAD-7, PHQ-9 and OHQ psychometric questionnaires. IPSS scores correlate significantly with the psychometric scores only when a non-parametric analysis is performed. IIEF and PEDT sexual function scores did not correlate with any of the psychometric tests. NIH-CPSI scores correlate positively with most of the TEMPS-A profiles but the hyperthymic profile correlated negatively with the total and QoL NIH-CPSI and with PEDT scores. CONCLUSIONS: Scores measuring anxiety, depression, and psychological well-being in patients with CP/CPPS are strictly correlated with prostatitis-like symptoms although they are poorly correlated with symptoms of prostatism, as measured by IPSS, and not correlated with scores of sexual dysfunctions, as measured by IIEF and PEDT. A hyperthymic temperament may increase resilience against the disease.

Is bulbospongiosus muscle botox injection safe and effective in treating lifelong premature ejaculation? Randomized controlled study.

PURPOSE: To evaluate the safety and efficacy of botulinum-A toxin injections into the bulbospongiosus muscle for cases of lifelong drug-resistant premature ejaculation (PE). METHODS: Ninety-eight outpatients diagnosed with lifelong PE were randomly assigned to two groups: the botulinum-A toxin group comprising forty-nine patients and the placebo (saline) group also consisting of forty-nine patients. A 100 U botulinum-A toxin was diluted into 10 cc of saline, with 5 cc injected into one side of the muscle (botulinum-A toxin group) guided by ultrasound to distribute across most muscle fibers. The same technique was applied using the same volume of saline injected into the bulbospongiosus muscle. Intravaginal ejaculatory latency time (IELT), scores from the premature ejaculation profile (PEP), Premature Ejaculation Diagnostic Tool (PEDT), International Index of Erectile Function (IIEF), and recording of any complications were obtained. Follow-ups occurred at 1-, 3-, and 6-month post-procedure. RESULTS: Cases receiving injections of botulinum-A toxin into the bulbospongiosus muscle showed notably extended intravaginal ejaculatory latency times compared to their initial performance after treatment. In addition, there were enhancements in PEP scores, and notably, no significant complications were reported. Conversely, the bilateral injection of saline into the bulbospongiosus muscle did not demonstrate any impact on ejaculation latencies. CONCLUSION: Our study demonstrated that the injection of botulinum-A toxin into the bulbospongiosus muscle can serve as a safe and effective option for treating PE. Nonetheless, its clinical application warrants further studies involving larger sample sizes and longer follow-up periods.

Overactive bladder negatively affects erectile function and promotes premature ejaculation: findings from large representative population-level study.

PURPOSE: The effect of overactive bladder (OAB) on sexual health has been evaluated extensively for women but much less for men. Therefore, the aim of this study was to evaluate the relationship between OAB and men's sexual activity and the effect of OAB on erectile dysfunction (ED) and premature ejaculation (PE) in a large representative cohort of men at the population level. METHODS: This study was based on computer-assisted web interviews that used validated questionnaires. The most recent census and the sample size estimation calculations were employed to produce a population-representative pool. RESULTS: The study included 3001 men, representative of the population in terms of age and place of residence. The frequency of sexual intercourse was higher for respondents without OAB symptoms compared with persons who had OAB (p = 0.001), but there was no association between OAB symptoms and number of sexual partners (p = 0.754). Regression models did not confirm the effect of OAB on sexual activity (odds ratio 0.993, CI 0.974-1.013, p = 0.511). Both ED and PE were more prevalent in respondents with OAB symptoms compared with persons who lacked those symptoms (p < 0.001). Importantly, the effect of OAB on ED or PE was independent of age, comorbidities, and lifestyle habits (regression coefficients of 0.13 and 0.158 for ED and PE, respectively). CONCLUSION: Overactive bladder did not significantly affect men's sexual activity, but it significantly correlated with ED and PE. Our results suggest a need in daily clinical practice to screen for OAB symptoms for persons who report ED or PE.

Analysis of orthostatic intolerance symptoms in patients with premature ejaculation.

OBJECTIVE: The autonomic nervous system (ANS) plays an important role in maintaining physiological regulation. It regulates the body's response to many variable situations. Orthostatic intolerance (OI) is one of the most important signs of autonomic dysfunction. Autonomic dysfunction is known to cause premature ejaculation (PE) by disturbing the balance in erection and ejaculation cycles. Considering that OI may develop due to autonomic dysfunction in patients with PE, we hypothesized that OI symptoms would increase in these patients. The aim of our study was to investigate the relationship between orthostatic intolerance and PE. PATIENTS AND METHODS: This case-control study included a total of 39 patients with PE and 47 volunteers without PE. All subjects were assessed using the self-reported Orthostatic Grading Scale (OGS). In addition, the validated five-item Turkish version of the Premature Ejaculation Diagnostic Tool (PEDT) was used to evaluate PE. The PE group included patients with a PEDT score ≥ 11. RESULTS: The mean ages of the PE and control groups were 38.2 ± 7.8 and 40.5 ± 9.1 years, respectively (p = 0.137). The mean PEDT scores of the PE and control groups were 13.9 ± 3.6 and 6.6 ± 2.9, respectively (p < 0.0001), and their mean OGS scores were 5.6 ± 2.4 and 1.6 ± 1.3, respectively (p < 0.0001). A statistically significant correlation was found between the PEDT and OGS scores (r: 0.686, p < 0.0001). CONCLUSIONS: The orthostatic intolerance symptoms of patients with PE were higher than those of the control group. There was a correlation between the severity of PE and the severity of orthostatic intolerance. This is the first study in the literature to reveal a relationship between orthostatic intolerance and PE.

The association of reproductive hormones, thyroid function, and vitamin levels with premature ejaculation: A prospective case-control study.

PURPOSE: To investigate whether serum hormone (testosterone, prolactin, gonadotropins, and thyroid hormones) and vitamin (vitamin B12, folic acid, and vitamin D) levels are associated with premature ejaculation (PE). MATERIALS AND METHODS: This prospective case-control study included 126 patients with PE (lifelong PE [LPE] in 94 and acquired PE [APE] in 32) who presented to the urology outpatient clinic between April 2016 and January 2023 and 92 healthy men as a control group. The diagnosis of PE was based on the criteria defined by the International Society for Sexual Medicine. Serum total testosterone (TT), free and bioavailable testosterone, follicle-stimulating hormone, luteinizing hormone, prolactin, thyroid-stimulating hormone, free triiodothyronine, thyroxine (fT4), vitamin B12, folic acid, and vitamin D levels were measured. RESULTS: Serum TT, fT4, and vitamin D levels were significantly higher in patients with PE than in the control group (p=0.022, p=0.002, and p=0.044, respectively). However, the serum vitamin B12 level was significantly lower in the PE group (p=0.021). In the multivariate logistic regression analysis, only vitamin B12 was found to be an independent risk factor for PE, with an estimated odds ratio of 0.997 (95% confidence interval 0.994-0.999, p=0.036). CONCLUSIONS: This study demonstrated that lower vitamin B12 levels are associated with the presence of PE. Therefore, we believe that it would be beneficial to consider vitamin B12 levels in the evaluation of patients with PE.

Effect of Serum Vitamin B12 Levels on Premature Ejaculation.

OBJECTIVE: To assess the impact of vitamin B12 levels in the failure of the dapoxetine used in premature ejaculation (PE) treatment. STUDY DESIGN: Experimental study. Place and Duration of the Study: Andrology Clinic, between May and December 2020. METHODOLOGY: Patients with premature ejaculation complaints completed the Premature Ejaculation Diagnostic Tool (PEDT) questionnaire. Patients were also asked to fill in the Premature Ejaculation Profile (PEP) surveys. Intravaginal ejaculation latency time (IELT) were recorded based on the estimates of patients. Serum vitamin B12 levels were evaluated based on blood samples. All patients were advised to use dapoxetine 30 mg, 1-3 hours prior to intercourse. After four weeks, patients were asked to complete the PEP questionnaire again. IELT times were recorded. RESULTS: A total of 62 patients were included in the study. A total of 39 patients (62.90%) were satisfied with the treatment of the dapoxetine. In comparison to patients who benefited from dapoxetine treatment and those who did not, vitamin B12 levels of patients who did not benefit from dapoxetine were found to be significantly lower (p=0.005). CONCLUSION: Vitamin B12 deficiency can reduce the effectiveness of dapoxetine treatment in patients with PE. It is important to evaluate serum vitamin B12 levels for the evaluation of patients with PE. KEY WORDS: Premature ejaculation, Dapoxetine, Vitamin B12, Serotonin, Treatment.

Men's views on causes and consequences of erectile dysfunction or premature ejaculation in a primary care population: a qualitative study.

OBJECTIVE: To explore men's views on the causes and consequences of two common sexual dysfunctions - erectile dysfunction and premature ejaculation - and how this affects physical and mental health as well as social life and intimate or close relations. DESIGN: A qualitative design with semi-structured interviews using open-ended questions was employed. Individual interviews were conducted, audio recorded and transcribed, and a qualitative content analysis of the text was performed. SETTING: Informants were recruited from an outpatient primary care clinic in Sweden that offers consultation about sexual health to primarily younger men, age 20 years and above. SUBJECTS: A total of 18 participants were included in the study, ten with erectile dysfunction and eight with premature ejaculation or both. MAIN OUTCOME MEASURES: Using the content analysis, different views and strategies of erectile dysfunction and premature ejaculation were presented to illustrate a range of perceptions. RESULTS: The main theme emerged as 'Striving to understand and deal with the problem', which was divided into four categories: 'Reasons for seeking healthcare', 'Own perceptions/images about the problem and its cause', 'Experienced consequences on sex life' and 'Relationship qualities'.Participants experienced their problems in relation to a partner. Feelings of shame and fear of not being fit for desired sexual practices were common. They thought that underlying physical illness or previous sexual activities could have caused their problems. Decreased sexual desire and low self-esteem were seen as consequences, and participants wished for both medical treatment and counselling as support. CONCLUSION: Sexual dysfunction impairs general health and relationships with partners. While counselling is the basic treatment, those who are offered pharmaceutical treatment need follow-up concerning effectiveness and potential concerns.

People with sexual dysfunction may have decreased quality of life and poorer somatic and mental health in general.People with sexual dysfunction may have few places to turn to in a traditional primary health care setting.The participants expressed concerns about their physical health, their relationships with partners and motivation for treatment.Men's visits to primary care for sexual dysfunction provides opportunities to talk about lifestyle and relationships and discover other illnesses.

Tarlov Cysts and Premature Ejaculation.

Tarlov cysts adjacent to the spinal cord are usually asymptomatic and found incidentally via magnetic resonance imaging. On rare occasions, they increase in size to produce symptoms resembling disk herniation. We report a rare case of a sacral cyst resulting in premature ejaculation in a 32-year-old man who presented with pelvic pain and acquired premature ejaculation. Spinal nerve root decompression, excision of intraspinal Tarlov cyst, and spinal nerve root adhesion release surgery significantly improved his pain and premature ejaculation at a six-month follow-up.

Impact of a Mediterranean diet on prevention and management of urologic diseases.

Compared to a Western diet, the Mediterranean diet moves away from red meat and processed foods. Universally regarded as a healthier dietary alternative, the Mediterranean diet has garnered scientific endorsement for its ability to confer an array of compelling benefits. These health benefits encompass not only a lowered incidence of Type 2 diabetes with a reduction in obesity, but also a robust protective effect on cardiovascular health. Extensive literature exists to corroborate these health benefits; however, the impact of a Mediterranean diet on urologic diseases, specifically sexual dysfunction, lower urinary tract symptoms, stone disease, and urologic cancers are not well studied. Understanding how dietary habits may impact these urologic conditions can contribute to improved prevention and treatment strategies.A total of 955 papers from PubMed and Embase were systematically reviewed and screened. After exclusion of disqualified and duplicated studies, 58 studies consisting of randomized controlled trials, cohort studies, cross sectional studies, reviews and other meta-analyses were included in this review. 11 primary studies were related to the impact of a Mediterranean diet on sexual dysfunction, 9 primary studies regarding urinary symptoms, 8 primary studies regarding stone disease, and 9 primary studies regarding urologic cancers. All primary studies included were considered of good quality based on a New-Castle Ottawa scale. The results demonstrate a Mediterranean diet as an effective means to prevent as well as improve erectile dysfunction, nephrolithiasis, lower urinary tract symptoms, and urinary incontinence. The review highlights the need for additional research to study the impact of diet on urologic cancers and other urologic conditions such as premature ejaculation, loss of libido, female sexual dysfunction, and overactive bladder.

Sexual dysfunction in men with young onset Parkinson's disease.

Sexual dysfunction (SD) is a common, yet under-reported non-motor symptom of PD. Common sexual symptoms among male PD patients include erectile dysfunction, premature ejaculation, and decreased sexual desire. Few research papers have examined sexual dysfunction in PD, especially in YOPD male patients, and there is no Indian research study on sexual dysfunction in YOPD. In this study, we determined the frequency of sexual dysfunction in men with YOPD, and its correlation with other motor and NMS. This prospective cross-sectional study was conducted on YOPD males who presented to the Department of Neurology, NIMHANS, Bangalore, India, from May 2021 to April 2023. The diagnosis of YOPD was made based on MDS criteria for IPD 2015. Sexual functions were evaluated by ASEX, PEDT, QUIP-RS, and sex hormone assay. The patients also underwent other motor and non-motor assessments. Statistical analysis was done using SPSS version 22.0. The study was funded by the PDMD fund. This study included 62 male YOPD patients. The mean age of cases was 44.74 ± 8.54 years. The mean duration of symptoms was 8.45 ± 6.23 years. 43.5% of the cases of PD were Akinetic rigid type. By ASEX Score grading, 46.8% of the cases had erectile dysfunction and 71% of the cases of YOPD had premature ejaculation by PEDT Score grading. 9.7% of the cases had hypersexuality by QUIP-RS. Duration of YOPD was a better predictor of Erectile Dysfunction and premature ejaculation when compared with other variables. SD was related to anxiety and depression and it had a negative impact on the patient's health-related quality of life (HR-QoL). SD should be investigated and treated as an integral part of the neurological assessment in YOPD.

A 2-week high-intensity interval training intervention improves ejaculation control among men with premature ejaculation.

BACKGROUND: Premature ejaculation (PE), which leads to substantial distress in men and their partners, is a common male sexual dysfunction worldwide. However, there is still a lack of effective treatments without side effects. OBJECTIVES: We investigated the effect of high-intensity interval training (HIIT) on PE symptoms. MATERIALS AND METHODS: We recruited 92 Chinese men aged 18-36 to complete the experiment. There were 22 (13 in the control group; 9 in the HIIT group) men diagnosed with PE and 70 (41 in the control group; 29 in the HIIT group) men with normal ejaculatory function. In the HIIT group, participants completed HIIT exercises every morning for 14 days. Participants also completed surveys inquiring about demographic information, erectile function, PE symptoms, body image (including sexual body image), physical activity, and sexual desire. The heart rate was measured before and after each HIIT. In the control group, participants were instructed not to do HIIT, but other procedures were the same as in the HIIT group. RESULTS: Results indicated that the HIIT intervention alleviated PE symptoms in men with PE. In addition, in the HIIT group, men with PE who had a higher heart-rate increase during the HIIT intervention reported the greatest overall decrements in PE symptoms. In men with normal ejaculatory function, HIIT did not decrease PE symptoms. In addition, increments in the heart rate during the intervention were associated with more pronounced PE symptoms post-intervention in this group. Analyses of secondary outcome measures suggested that the HIIT intervention improved general and sexual body image satisfaction of men with PE compared to before the intervention. DISCUSSION AND CONCLUSION: In summary, HIIT intervention may reduce PE symptoms in men with PE. The heart-rate increase during the intervention may be a key factor influencing the effect of the HIIT intervention on PE symptoms.

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.

Do Ejaculation Latency and Other Sexual Measures Differ Between Men With Lifelong and Acquired Premature Ejaculation?

OBJECTIVE: To determine whether men with lifelong vs acquired premature ejaculation (PE) subtypes differ on their estimated ejaculation latencies (EL) and related sexual, relationship, and behavioral parameters. METHODS: Of 2679 men who responded to an online multinational survey about sexual health and met inclusion criteria, 540 reported "probable" or "definite" PE, as assessed by the Premature Ejaculation Diagnostic Tool. Lifelong and acquired PE subtypes were compared on multiple measures related to EL, as well as on sets of demographic, diagnostic, relationship, sexual behavioral, and sexual functioning measures during both partnered sex and masturbation. RESULTS: Nearly 73% of men with PE in this sample reported the lifelong subtype. No differences emerged in EL measures between subtypes, even when parsed according to age. Specifically, men 37years or under with either definite lifelong or acquired PE reported ELs of 1.9 minutes (SD=1.3). For men over 37, lifelong ELs were 2.0 minutes (SD=1.3), acquired ELs 2.4 minutes (SD=1.4). While the lifelong subgroup was younger and reported lower erectile functioning, these differences occurred only in the probable PE group and not the definite PE group. CONCLUSION: Our data do not support different EL criteria for men with acquired vs lifelong PE, as suggested by several professional definitions. Furthermore, differences in age and erectile functioning between the groups, often reported in clinical samples though not in our definite PE group, may be an artifact of the general health/patient characteristics that lead such men to seek medical assistance.

Perceived intravaginal ejaculation latency time: The diagnosis of premature ejaculation among Vietnamese men.

INTRODUCTION: Premature ejaculation (PE) is a prevalent sexual dysfunction in men that greatly affects their quality of life. In PE, the duration of sexual performance is considered an important aspect. However, a self-estimated value of intravaginal ejaculation latency time (perceived IELT, PIELT) as a criterion for diagnosis has not been specified. AIM: This study aimed to determine the validity and a threshold value for PIELT in PE diagnosis. METHOD: In our cross-sectional study, we recruited 550 men from March 2019 to January 2020 and interviewed them regarding their general demographic characteristics, sexual habits, PIELT and completed a premature ejaculation diagnostic tool (PEDT) questionnaire. Eventually, a combination of a clinical diagnosis and PEDT score was used, in which those with PEDT ≥ 11 and diagnosed with possible PE were assigned to the final PE(+) group; those with PEDT score ≤ 8 and diagnosed with no PE were included in the final PE(-) group. RESULTS: Men PE(-) had more frequent sexual intercourse (9.74 ± 5.38 vs. 6.69 ± 5.38 episodes per month, p < 0.001) and had higher marriage rate (72.7% vs. 60.4%, p = 0.002) than PE(+) patients. No significant difference was noted regarding age, smoking habit, age of first sexual experience, and number of sexual partners between the two groups. The mean PIELT of control subjects and PE(+) patients were 11.69 ± 6.83 min and 2.01 ± 1.21 min, respectively. On receiver operating characteristic curve analysis, the cut-off value of PIELT of 3.75 min can be used to distinguish PE men (area under the curve = 0.982, sensitivity/specificity = 0.961/0.909), which means that men with a PIELT ≤ 3.5 min is suggestive of PE. CONCLUSION: The impact of PE is dramatic both from a social and a personal perspective. PE(+) patients married significantly less and have significantly lower sexual activity compared to a PE(-) population. Furthermore, a PIELT of ≤ 3.5 min predicts PE demonstrating the need to revise its taxonomy and definition.

From Waterloo to the Great Wall: A retrospective, multicenter study on the clinical practice and cultural attitudes in the management of premature ejaculation, in China.

Premature ejaculation (PE), despite its wide prevalence, is largely underdiagnosed and undertreated. Being a multifactorial dysfunction with strong cultural characteristics, PE requires skillful attitudes in the psychosexological support, necessary to manage the patient's and the couple's expectations, as well as in the medical treatment. Dapoxetine is a short-acting selective serotonin reuptake inhibitor approved for use in lifelong and acquired PE in a number of countries. Opinions, not always generated by the evidence-based medicine, impacted the attitudes of Western andrologists, as a nocebo effect which produced a drug's Waterloo, characterized by low prescription rates much more built on the patients' and doctors' expectations than on costs, side effects, and efficacy. In the present study, we retrospectively reviewed real-life data from eight Andrology and Sexual Medicine Public Centers in China to assess the prevalence of PE among attending patients, its association with erectile dysfunction, its subtype, and the proposed treatments. In 2019, among 156,486 patients coming to the centers, 32,667 visits having PE as the chief complaint were performed (20.9%). Almost all patients received treatment prescriptions (32,641 patients, 99.92%); 23,273 patients came back for a follow-up visit in the subsequent 12 months (71.2% of those who initially received treatment). Dapoxetine, either alone or in combination with another therapy, was the most prevalent treatment, prescribed to 22,767 patients (69.7% of treated patients), followed by traditional Chinese medicine (TCM) (39.4%). At follow-up, 8174 patients were unsatisfied with treatment, and a new treatment was proposed (35.12%). Dapoxetine was the best treatment, with an overall 27.1% switching rate when used either alone or in combination: Although the switching rate for Dapoxetine alone was 44.2%, the association of the same drug with psychotherapy resulted in much lower rates (19.5%) and reached a minimum of 12% when also combined with TCM demonstrating how cultural aspects and medical attitudes may dramatically impact on the therapy of a multifaceted, complex, and culture-grounded sexual symptom such as PE. In conclusion, taking switching rates as surrogate markers of treatment failure, this real-life study-the largest in the field-shows that in a more patient-oriented (as in Chinese medical culture), and less symptom-oriented (as in Western medical attitudes), Dapoxetine is a successful treatment for PE patients, with higher reliability when used alone or as part of combined and integrated therapies.

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. TRIAL REGISTRATION: Chinese Clinical Trial Registry (ChiCTR2300070581).

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.
