A previous study showed that the length of the foreskin plays a role in the risk of sexually transmitted infections and chronic prostatitis, which can lead to poor quality of sexual life. Here, the association between foreskin length and sexual dysfunction was evaluated. A total of 5700 participants were recruited from the andrology clinic at The First Affiliated Hospital of University of Science and Technology of China (Hefei, China). Clinical characteristics, including foreskin length, were collected, and sexual function was assessed by the International Index of Erectile Function-5 (IIEF-5) and Premature Ejaculation Diagnostic Tool (PEDT) questionnaires. Men with sexual dysfunction were more likely to have redundant foreskin than men without sexual dysfunction. Among the 2721 erectile dysfunction (ED) patients and 1064 premature ejaculation (PE) patients, 301 (11.1%) ED patients and 135 (12.7%) PE patients had redundant foreskin, respectively. Men in the PE group were more likely to have redundant foreskin than men in the non-PE group ( P = 0.004). Logistic regression analyses revealed that the presence of redundant foreskin was associated with increased odds of moderate/severe ED (adjusted odds ratio [aOR] = 1.31, adjusted P = 0.04), moderate PE (aOR = 1.38, adjusted P = 0.02), and probable PE (aOR = 1.37, adjusted P = 0.03) after adjusting for confounding variables. Our study revealed a positive correlation between the presence of redundant foreskin and the risk of sexual dysfunction, especially in PE patients. Assessment of the length of the foreskin during routine clinical diagnosis may provide information for patients with sexual dysfunction.

OBJECTIVE:
To investigate the clinical effect and adverse reactions of dapoxetine hydrochloride versus paroxetine in the treatment of primary premature ejaculation by cross-comparison.
METHODS:
Based on the clinic-visit time, we equally randomized 148 patients with primary premature ejaculation into groups A and B for a cross-comparison test, the former treated with paroxetine at 20 mg once nightly and the latter with dapoxetine hydrochloride at 30 mg on demand, both for 6 successive weeks, during which we observed the therapeutic effects and adverse reactions. Following 4 weeks of drug discontinuance, we administered dapoxetine hydrochloride at 30 mg on demand for group A and paroxetine at 20 mg once nightly for group B, both for another 6 successive weeks, followed by observation and comparison of the therapeutic effects and adverse reactions.
RESULTS:
There were no statistically significant differences in the initial characteristics of the two groups of patients (P > 0.05). Compared with the baseline, the mean intra-vaginal ejaculation latency time (IELT) was dramatically improved after treatment in both groups A (4.43 min) and B (7.12 min), increased by 3.99% and 6.72%, respectively (P<0.001). The patients treated with paroxetine showed significantly longer IELT than those taking dapoxetine hydrochloride in both groups (P<0.001). Findings of the Premature Ejaculation Profile (PEP) and spouses' conditions indicated significant improvement after treatment in the average scores of the four indicators of PEP, that is, perceived control over ejaculation, ejaculation-related personal distress, satisfaction with sexual intercourse and ejaculation-related interpersonal difficulty, as well as in the overall experience and partner's satisfaction and orgasm frequency. Adverse reactions to medication were found in 20.8% of the cases in group A and 9.7% in group B, but none was serious. Preference survey following drug withdrawal revealed a preference for paroxetine (61.9%) over dapoxetine (26.8%), and that only a few of the patients thought of the two drugs as comparable or both ineffective.
CONCLUSION
In term of overall effectiveness, paroxetine was superior to dapoxetine in the treatment of primary premature ejaculation. And the patients obviously preferred the former to the latter, which might be partly attributed to the higher price of dapoxetine.

Magnetic resonance imaging (MRI), as a non-invasive neuroimaging technique, has been widely employed to investigate changes in functional brain regions. In recent years, the application of MRI in the study of lifelong premature ejaculation (LPE) has progressively uncovered the pathological mechanisms underlying abnormalities in LPE-associated brain regions. These mechanisms involve brain areas associated with higher-order cognitive and decision-making regulation, sensory and perceptual processing, as well as emotional regulation and reward systems. The application and findings of MRI in the study of LPE mechanisms will be introduced in this review, with the goal of deepening our understanding of the neuroimaging-based mechanisms of LPE.

OBJECTIVE:
To investigate the clinical efficacy of Zhuangdan Yanshi Decoction combined with dapoxetine hydrochloride in the treatment of premature ejaculation with cholestasis and phlegm disturbance.
METHODS:
A total of 120 patients diagnosed with premature ejaculation and treated in the Andrology Outpatient Department of Shaanxi Provincial Hospital of Traditional Chinese Medicine from March to December in 2022 were selected and randomly divided into treatment group and control group, with 60 cases in each group. The incubation period of intravaginal ejaculation (IELT), the Diagnostic Scale of Premature Ejaculation (PEDT), the Premature Ejaculation Assessment Scale (PEP), the 5-item Sexual Function Evaluation of Chinese Premature Ejaculation Patients (CIPE-5) and the improvement of traditional Chinese medicine symptom scores were compared before and after the treatment. And the adverse reactions were recorded as well.
RESULTS:
A total of 105 cases were ultimately included, with 55 cases in the treatment group and 50 cases in the control group. Measurable improvements in IELT, PEDT scores, PEP scores, CIPE scores and TCM symptom scores had been found after treatment in both of two groups (P<0.05). Moreover, the improvement in the treatment group was superior to that in the control group (P<0.05). The total effective rate in the treatment group was 89.1%, which was higher than that(84%) in the control group, with no statistically significant difference between the two groups (P>0.05). The incidence of adverse reactions in the treatment group was 9.1%, which was 24% in the control group. There was significantly difference between two groups (P<0.05).
CONCLUSION
The combination therapy with Zhuangdan Yanshi Decoction and dapoxetine hydrochloride for premature ejaculation associated with cholestasis and phlegm disturbance syndrome is definite, and it can reduce the side effects of drugs, which is better than oral dapoxetine hydrochloride alone.

OBJECTIVE:
To explore the mediating role of the partner's dyadic coping in improving the stigma and quality of life (QOL) of the patient with premature ejaculation (PE).
METHODS:
We selected 480 PE patients seeking medical care in the clinic of urology and andrology from January to June 2023 by convenience sampling. Using a General Information Questionnaire, Dyadic Coping Inventory, Social Impact Scale, and Short-Form 12 Quality of Life Scale, we conducted an investigation among the patients and analyzed the mediation effect of the partner's dyadic coping on the patients' stigma and QOL.
RESULTS:
The mean scores on the partner's dyadic coping and the patients' stigma and QOL were (68.58±14.96), (47.67±30.13) and (90.18±28.93), respectively, with a significant correlation between the partner's dyadic coping and the patients' stigma and QOL (P<0.01). And the partner's dyadic coping was found to have an evident mediating role in improving the stigma and QOL of the patients, with a mediation effect of 36.38% of the total effect.
CONCLUSION
The QOL of the PE patients is at a below-average level, and the partner's dyadic coping plays a mediating role in improving the stigma and QOL of the patients. Design of dyadic coping-related intervention plans is recommended to improve the partner's dyadic coping, reduce the stigma of the patients and increase their QOL.

Selective dorsal neurotomy (SDN) is a surgical treatment for primary premature ejaculation (PE), but there is still no standard surgical procedure for selecting the branches of the dorsal penile nerves to be removed. We performed this study to explore the value of intraoperative neurophysiological monitoring (IONM) of the penile sensory-evoked potential (PSEP) for standard surgical procedures in SDN. One hundred and twenty primary PE patients undergoing SDN were selected as the PE group and 120 non-PE patients were selected as the normal group. The PSEP was monitored and compared between the two groups under both natural and general anesthesia (GA) states. In addition, patients in the PE group were randomly divided into the IONM group and the non-IONM group. During SDN surgery, PSEP parameters of the IONM group were recorded and analyzed. The differences in PE-related outcome measurements between the perioperative period and 3 months' postoperation were compared for the PE patients, and the differences in effectiveness and complications between the IONM group and the non-IONM group were compared. The results showed that the average latency of the PSEP in the PE group was shorter than that in the normal group under both natural and GA states (P < 0.001). Three months after surgery, the significant effective rates in the IONM and non-IONM groups were 63.6% and 34.0%, respectively (P < 0.01), and the difference in complications between the two groups was significant (P < 0.05). IONM might be useful in improving the short-term therapeutic effectiveness and reducing the complications of SDN.

Recent research has highlighted structural and functional abnormalities in the cerebral cortex of patients with premature ejaculation (PE). These anomalies could play a pivotal role in the physiological mechanisms underlying PE. This study leveraged functional magnetic resonance imaging (fMRI), a noninvasive technique, to explore these neural mechanisms. We conducted resting-state fMRI scans on 36 PE patients and 22 healthy controls (HC), and collected data on Premature Ejaculation Diagnostic Tool (PEDT) scores and intravaginal ejaculation latency time (IELT). Employing a surface-based regional homogeneity (ReHo) approach, we analyzed local neural synchronous spontaneous activity, diverging from previous studies that utilized a volume-based ReHo method. Areas with significant ReHo differences between PE and HC groups underwent surface-based functional connectivity (FC) analysis. Significant discrepancies in ReHo and FC across the cortical surface were observed in the PE cohort. Notably, PE patients exhibited decreased ReHo in the left triangular inferior frontal gyrus and enhanced ReHo in the right middle frontal gyrus. The latter showed heightened connectivity with the left lingual gyrus and the right orbital superior frontal gyrus. Furthermore, a correlation between ReHo and FC values with PEDT scores and IELT was found in the PE group. Our findings, derived from surface-based fMRI data, underscore specific brain regions linked to the neurobiological underpinnings of PE.

PURPOSE: To determine the role of metabolic syndrome (MetS) as a risk factor for acquired premature ejaculation (PE) after considering the various risk factors, such as lower urinary tract symptoms, erectile dysfunction, hypogonadism, and prostatitis. MATERIALS AND METHODS: From January 2012 to January 2017, records of 1,029 men were analyzed. We performed multivariate analysis to identify risk factors for PE, including the covariate of age, marital status, International Prostate Symptom Score, International Index of Erectile Function (IIEF) score, National Institutes of Health-Chronic Prostatitis Symptom Index (NIH-CPSI) score, serum testosterone levels, and all components of MetS. Acquired PE was defined as self-reported intravaginal ejaculation latency time ≤3 minutes, and MetS was diagnosed using the modified National Cholesterol Education Program Adult Treatment Panel III criteria. RESULTS: Of 1,029 men, 74 subjects (7.2%) had acquired PE and 111 (10.8%) had MetS. Multivariate analysis showed that the IIEF overall satisfaction score (odds ratio [OR]=0.67, p<0.001), NIH-CPSI pain score (OR=1.07, p=0.035), NIH-CPSI voiding score (OR=1.17, p=0.032), and presence of MetS (OR=2.20, p=0.022) were significantly correlated with the prevalence of acquired PE. In addition, the Male Sexual Health Questionnaire for Ejaculatory Dysfunction scores and ejaculation anxiety scores progressively decreased as the number of components of MetS increased. CONCLUSIONS: MetS may be an independent predisposing factor for the development of acquired PE. Effective prevention and treatment of MetS could also be important for the prevention and treatment of acquired PE.

PURPOSE: Although the prevalence of erectile dysfunction (ED) can be affected by social changes, this association has not been well evaluated. We aimed to evaluate the prevalence and risk factors of ED through a 10-year-interval web-based survey using the previous database of same group of panels, with same methodology. MATERIALS AND METHODS: We sent e-mails and surveyed the panels registered in the Internet survey agency. RESULTS: In total, 900 participants were recruited in 2016. The age-adjusted overall prevalences of self-reported ED (self-ED) and International Index of Erectile Function-5-assessed ED (IIEF-5-ED; score ≤21) in the 2016 study were 3.2% and 44.8%, respectively, which were lower than the prevalences of 8.1% (p=0.036) and 51.4% (p=0.323), respectively, in the 2006 study. The risk factors of IIEF-5-ED in their 20s and 30s in 2016 were psycho-social factors such as depression, low frequency of conversation about sex with sexual partner. The risk factors of IIEF-5-ED in their 40s to 60s in 2016 were organic factors, such as hypertension, diabetes mellitus, smoking, alcohol use, and self-reported premature ejaculation. CONCLUSIONS: Although the age-adjusted overall prevalence of self-ED has decreased during a decade, there was no difference in the age-adjusted overall prevalence of IIEF-5-ED. Psycho-social support may be important for young men with ED and overall healthcare can be helpful for elderly men with ED.
