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.

Evaluating the Aphrodisiac Potential of Mirabilis jalapa L. Root Extract: Phytochemical Profiling and In Silico, In Vitro, and In Vivo Assessments in Normal Male Rats.

The traditional use of Mirabilis jalapa L. roots to enhance male sexual performance prompted us to assess the in silico, in vitro, and in vivo aphrodisiac activities of its hydroethanolic extract using normal male rats. Spectroscopic characterization indicated the presence of ß-D-glucopyranoside, methyl-1,9-benzyl-2,6-dichloro-9H-purine, and Bis-(2-ethylhexyl)-phthalate; these compounds have a significant inhibitory effect on the phosphodiesterase-5 (PDE-5) enzyme in silico evaluation and minerals (including zinc, cadmium, and magnesium). Other phytochemical analyses revealed the presence of phenolic compounds and flavonoids. These phytochemicals and minerals may contribute to the aphrodisiac activities of the extract. Additionally, the in vivo study revealed that the administration of M. jalapa root extract (300 mg/kg) significantly enhanced (p < 0.01, p < 0.03) mount, intromission, and ejaculation frequencies while significantly (p < 0.05) decreasing the mount and intromission latencies, as well as the post-ejaculatory interval time, in comparison with the standard drugs sildenafil and ginseng, resulting in enhanced erection and sexual performance in the rats. Furthermore, the extract significantly (p < 0.05) increased penile reflexes and also elevated the levels of testosterone and luteinizing hormones. Extract (300 mg/kg) significantly (p < 0.05) inhibited the PDE-5 enzyme in an in vitro study. Concludingly, the comprehensive findings of this study suggest that a standardized herbal extract derived from M. jalapa roots alleviates erectile dysfunction and premature ejaculation in male rats. M. jalapa root extract proved to be an alternative treatment for erectile dysfunction and premature ejaculation.

Traditional, Complementary and Alternative Medicines in the Treatment of Ejaculatory Disorders: A Systematic Review.

Background and Objectives: Ejaculatory dysfunction (EjD) is a common male sexual disorder that includes premature ejaculation, delayed ejaculation, retrograde ejaculation, and anejaculation. Although psychological and pharmacological treatments are available, traditional, complementary, and alternative medicine (TCAM) is reportedly used. However, the clinical evidence for TCAM in EjD remains unclear. Therefore, this study aims to systematically review human clinical trials investigating the use of TCAM to treat EjD. Materials and Methods: A systematic review of the literature following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted by searching Scopus and PubMed databases. Controlled clinical trials investigating a cohort of male patients diagnosed primarily with EjD and undergoing any TCAM intervention compared to any comparison group were included. Quality of the studies was assessed using the Cochrane Risk of Bias tool for randomized controlled trials. Results: Following article screening, 22 articles were included. Of these, 21 investigated TCAM in premature ejaculation, and only 1 investigated TCAM in retrograde ejaculation. Different TCAM categories included studies that investigated lifestyle, exercise and/or physical activities (n = 7); herbal medicine supplements (n = 5); topical herbal applications (n = 4); acupuncture or electroacupuncture (n = 3); vitamin, mineral and/or nutraceutical supplements (n = 1); hyaluronic acid penile injection (n = 1); and music therapy (n = 1). Only 31.8% (n = 7) of the included studies were found to have a low risk of bias. The available studies were widely heterogenous in the TCAM intervention investigated and comparison groups used. However, the included studies generally showed improved outcomes intra-group and when compared to placebo. Conclusions: Different TCAM interventions may have an important role particularly in the management of PE. However, more studies using standardized interventions are needed.

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

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

Selective serotonin reuptake inhibitors combined with traditional Chinese medicine for premature ejaculation: A systematic review and meta-analysis.

BACKGROUND: Premature ejaculation (PE) is still a tough problem in drug treatment. Many clinical trials have proven that traditional Chinese medicine (TCM) has a significant effect in the treatment of PE. This article aims to provide the latest evidence for the efficacy and safety of TCM combined with selective serotonin reuptake inhibitors (SSRIs) in the treatment of PE. METHODS: We looked for randomized controlled trials (RCTs) from China National Knowledge Infrastructure, Wanfang, VIP Database, MEDLINE, PubMed, Web of Science, EMBASE, and Cochrane Library until June 30, 2022. STATA 15.1 software was used to analyze all data for this article. The quality of the included articles was evaluated using the Cochrane Reviewer's Handbook 5.3. RESULTS: Finally, we selected 16 high-quality RCTs in our meta-analysis, which containing 889 patients. Meta-analysis suggested that, compared with SSRIs alone, combination of TCM with SSRIs increased significantly intravaginal ejaculation latencv time and the scores of ejaculation control ability, sexual life satisfaction, PE-related distress, and communication difficulties between partners related to PE. Also, there was no significant difference in adverse effects between the two groups. In addition, the results of publication bias test showed that no significant bias occurred. CONCLUSION: The combined use of TCM and SSRIs has significant effect in the treatment of PE compared with SSRIs monotherapy and was generally well tolerated. Due to the small sample size, multicenter and large sample RCT is still needed in the future to further confirm the effectiveness and safety of TCM combined with SSRIs in the treatment of PE.

[Clinical efficacy of Manlyman Spray combined with biofeedback therapy on premature ejaculation].

Objective： To observe the clinical effect of Manlyman Spray combined with biofeedback therapy in the treatment of premature ejaculation (PE)．Methods： A total of 60 primary premature ejaculation patients with stable sexual partners and regular sexual activity (≥１ times per week) from April 2021 to October 2022 were involved in the clinical observation, The patients' age is (34.3 ± 4.9) years old, and the course of the disease is (112.5 ± 65.5) months, and Manlyman Spray combined with biofeedback therapy was used to treat patients for 8 weeks. Manlyman Spray was sprayed 3 times on the surface of the penisqd for 4 weeks, and Biofeedback therapy is treated twice a week according to the AI setting module, for a total of 8 weeks. Before and 8 weeks after medication and at 4 weeks after drug withdrawal, the Intravaginal Ejaculation Latency Time (IELT), Premature Ejaculation Diagnostic Tool (PEDT) scores and Clinical Global Impression of Change (CGIC) scores were Obtained and compared. Results： After 8 weeks of treatment, the IELT of the patients was significantly prolonged (ï¼»351.4 ± 76.7ï¼½ vs ï¼»87 ± 16.8ï¼½,P<0.05) and at 4 weeks after drug withdrawal, the therapeutic effect still existed (ï¼»345.9 ± 80.3ï¼½ vs ï¼»87 ± 16.8ï¼½,P<0.05), the PEDT scores were significantly improved after treatment (ï¼»18.2 ± 1.1ï¼½ vs ï¼»9.0 ± 1.4ï¼½,P<0.05)and at 4 weeks after drug withdrawal(ï¼»18.0 ± 1.2ï¼½ vs ï¼»9.0 ± 1.4ï¼½,P<0.05), and so were the CGIC scores (ï¼»13.4 ± 1.3ï¼½ vs ï¼»3.3 ± 1.4ï¼½,P<0.05, and ï¼»12.6 ± 1.6ï¼½ vs ï¼»3.3 ± 1.4ï¼½,P<0.05). Conclusion： The combination of Manlyman Spray and biofeedback therapy can effectively treat primary premature ejaculation, with a long duration of treatment and good safety, and the specific mechanism needs further study.

Gaps in the management of diabetes in Asia: A need for improved awareness and strategies in men's sexual health.

Sexual dysfunction, which is defined as 'difficulty during any stage of the sexual encounter that prevents or impairs the individual or couple from enjoying sexual activity', is globally prevalent in males with prediabetes and diabetes. It is an early harbinger of cardiovascular diseases and has a profound impact on one's physical, mental, and social health. Among patients with either prediabetes or diabetes, the most common male sexual dysfunctions are hypogonadism, erectile dysfunction, and premature ejaculation. In Asia, although sexual health is an important factor of men's health, it is rarely discussed freely in real-life practice. Addressing sexual health in Asian males has always been challenging with multiple barriers at the levels of patients and health care providers. Therefore, the assessment and management of sexual dysfunction in routine clinical practice should involve a holistic approach with effective patient-provider communication. In this review, we discuss the epidemiology, pathophysiology, and the management of hypogonadism, erectile dysfunction, and premature ejaculation among males with either prediabetes or diabetes (type 1 and type 2), as well as the evidence gaps across Asia.

Efficacy of combination therapy with biofeedback and dapoxetine in lifelong premature ejaculation treatment: a prospective randomized study.

PURPOSE: Premature ejaculation (PE) is a common sexual dysfunction that significantly affects the quality of life of the patient and their partner. We aimed to compare the efficacy and safety of the combination therapy with biofeedback-guided pelvic floor exercise therapy (BFT) and dapoxetine 30 mg. METHODS: Sixty-five patients diagnosed with lifelong PE were included in the study. Patients were divided into three groups as BFT, dapoxetine 30 mg and a combination of BFT and dapoxetine 30 mg. The patients were compared with the intravaginal ejaculatory latency time (IELT) pre-treatment and post-treatment 1st and 3rd months. RESULTS: The mean IELTs of the patients in Group 1 were 40 s in pre-treatment, 115 s at the end of the 4th week and 140 s at the end of the 12th week. The IELT values of the patients in Group 2 were 40 s in pre-treatment, 145 s in the 4th week and 170 s in the 12th week. The IELT values were calculated in Group 3 as 42.5 s in pre-treatment, 185 s in the 4th week and 205 s in the 12th week When the IELT was statistically compared between the groups at 1st and 3rd months, the duration in the combination group was found to increase significantly (p < 0.001). CONCLUSION: Combination therapy with BFT and dapoxetine 30 mg in lifelong PE treatment is a good alternative with a low side effect profile and acceptable continuous efficiency.

Hypothalamic-related neural mechanism in lifelong premature ejaculation and trends following selective serotonin reuptake inhibitor administration.

Lifelong premature ejaculation patients had altered structural and functional parameters of the hypothalamus compared with healthy controls. The patients showed increased hypothalamus-related functional connectivity in several regions one hour after dapoxetine administration. The changing trends of the brain functional connectivity after dapoxetine administration possibly provided important information about the selective serotonin reuptake inhibitor effects on the functional neural system.

Study on the Efficacy of Electric Acupuncture in the Treatment of Premature Ejaculation Based on Testosterone Level.

Objective: To investigate the clinical efficacy and possible mechanism of electroacupuncture in the treatment of premature ejaculation. Methods: 50 cases of premature ejaculation patients who met the diagnostic criteria were randomly divided into 2 groups with 25 cases in each group. The observation group was treated with electroacupuncture, and the control group was treated with Longdan Xiegan decoction. The treatment period was 4 weeks. Ejaculation latency (IELT), sexual satisfaction score of patients, sexual satisfaction score of partners, testosterone test, and drug safety assessment were performed in all 4 groups before and after treatment. Results: IELT was prolonged in all groups after treatment, the difference was statistically significant (P < 0.05). At the same time, the IELT of the observation group was significantly higher than that of the control group after treatment. Life satisfaction scores of patients and spouses in 2 groups were improved after treatment compared with before treatment, the difference was statistically significant (P < 0.05). After treatment, the satisfaction scores of patients and spouses in the observation group were higher than those in the control group, and the difference was statistically significant (P < 0.05). Before treatment, there was no significant difference in serum testosterone levels among all groups (P > 0.05). Serum testosterone levels in all groups were decreased after treatment compared with before treatment, with statistical significance (P < 0.05). After treatment, the serum testosterone level of the observation group was lower than that of the control group, and the difference was statistically significant (P < 0.05). During the treatment, the adverse reactions in each group disappeared after treatment, and no obvious abnormality was observed in the safety indicators. Conclusion: Electroacupuncture can improve the symptoms of premature ejaculation, which may be related to the regulation of serum testosterone by acupuncture.

An up-to-date overview of the pharmacotherapeutic options for premature ejaculation.

INTRODUCTION: Premature ejaculation (PE) is a sexual dysfunction of unknown etiology affecting a substantial number of males and deteriorating sexual health and quality of life of the patient and his partner. Treatment still remains challenging; however, pharmacotherapy is considered the mainstay of therapy with behavioral and psychosexual interventions being particularly important as adjudicate procedures, within the context of a holistic approach. AREAS COVERED: The authors review the literature on the available medications for PE, both officially registered and non-registered. Currently, only dapoxetine and an anesthetic spray containing lidocaine and prilocaine (Fortacin™) are officially approved, with the rest being used off-label. Herein, updated data regarding the efficacy and safety of the pharmaceutical agents are presented. EXPERT OPINION: On-demand dapoxetine is reportedly efficacious and safe in treating lifelong PE and is the first medication to be approved for this purpose. Fortacin has also shown considerable efficacy and may be reliably used on-demand. Phosphodiesterase type 5 inhibitors (PDE5Is) have been found to be effective in the treatment of PE and are therefore recommended either as monotherapy or combined with other therapies (i.e. dapoxetine). Adverse events of any therapy should be taken under consideration. Physicians should encourage patients to discuss their needs and expectations and grade any improvement of their condition with treatment.

[Action mechanism of Professor Xu Fusong's Shuilu Erxian Dan in the treatment of premature ejaculation: An exploration based on network pharmacology and molecular docking technology].

OBJECTIVE: To analyze the potential action mechanism of Shuilu Erxian Dan in the treatment of premature ejaculation based on network pharmacology. METHODS: The TCMSP database was searched for the main chemical constituents of Euryale and golden cherry, the core components of Shuilu Erxian Dan. Oral bioavailability and medicinal properties were set as the parameters for screening active components, premature ejaculation-related disease targets retrieved from the DisGeNET, GeneCards, OMIM and TTD databases, the common targets of drug pairs and diseases identified with the Wayne diagram, and a drug-active ingredient-target-disease network map constructed with the software Cytoscape. A PPI network map designed through the STRING platform, the website Metascape used for GO and KEGG analyses of the common targets, and the protein receptors and small molecular ligands of the core genes employed for molecular docking and PyMOL visualization. RESULTS: A total of 7 chemical constituents and 171 predictive targets, 1 918 premature ejaculation targets and 113 common targets were identified. GO analysis showed significant enrichment of BP in response to toxic substances and inorganic substances, CC in membrane raft and plasma membrane protein complex, and MF in transcription factor binding and kinase binding. KEGG analysis manifested markedly enriched TNF signaling pathway, JAK-STAT signaling pathway and Cocaine addiction. The results of molecular docking exhibited a good binding energy between the core gene and the component. CONCLUSION: Network pharmacology has revealed the potential action mechanism of Shuilu Erxian Dan in the treatment of premature ejaculation, which has paved the theoretical ground for verification of the effectiveness of Shuilu Erxian Dan in the treatment of premature ejaculation via animals and cells.

[Correlations between resting-state brain functional characteristics and TCM syndrome in premature ejaculation patients with heart-kidney disharmony].

OBJECTIVE: To investigate the correlation between the characteristics of resting-state brain function and the types of traditional Chinese medicine (TCM) syndrome in premature ejaculation (PE) patients with heart-kidney disharmony, and the pathogenesis of abnormal ejaculation of the patients. METHODS: We enrolled 33 PE patients with heart-kidney disharmony and 32 healthy controls matched in general demographic data, evaluated the severity of the main and concurrent symptoms of PE using the PE Diagnostic Tool (PEDT) and TCM Syndrome Scale (TCMSS), and obtained the brain structural and functional MRI data. We processed the collected data and calculated the amplitude of low-frequency fluctuations (ALFF), fractional ALFF (fALFF) and regional homogeneity (Reho) of the brain with the DPABI software. Using the REST software package, we compared the significantly different brain areas between the PE and control groups by two-sample t-test and corrected the results for multiple comparisons by AlphaSim, followed by Pearson correlation analysis of ALFF, fALFF and Reho in abnormal brain areas and the PEDT and CMSS scores of the patients. RESULTS: The PE patients showed decreased ALFF values in the bilateral inferior temporal gyrus, left middle frontal gyrus and left orbital part of the inferior frontal gyrus, and increased ALFF values in the bilateral hippocampus, thalamus and precuneus, right inferior occipital gyrus, right calcarine and left inferior parietal, with positive correlations of the ALFF values of the left thalamus with the scores on PEDT (r = 0.35, P < 0.05) and TCMSS (r = 0.44, P < 0.05). The fALFF values of the patients were also decreased in the left temporal pole of the middle temporal gyrus and left anterior cingulate gyrus, but increased in the left inferior temporal gyrus. The Reho values of the patients were decreased as well in the right inferior temporal gyrus, left middle frontal gyrus, right dorsolateral superior frontal gyrus, right middle occipital gyrus, right middle occipital gyrus and right precuneus, but increased in the left temporal pole of the middle temporal gyrus, left middle frontal gyrus and left superior frontal gyrus, with negative correlations between the Reho value of the right superior parietal gyrus and TCMSS scores (r = －0.35, P < 0.05). CONCLUSION: Abnormal brain regions were found in PE patients with heart-kidney disharmony, with might be the pathologically associated with PE symptoms and heart-kidney disharmony of the patients.

Thalamocortical Dysconnectivity In Lifelong Premature Ejaculation: A Functional MRI Study.

OBJECTIVES: To detect seed-based functional connectivity (FC) between various cortical sub-regions and the thalamus in lifelong premature ejaculation (LPE) patients and explore whether specific thalamocortical networks are significantly altered in PE patients compared to healthy controls (HCs) METHODS: Fifty non-medicated LPE patients and 40 age-matched HCs underwent a resting-state functional MRI. FC was adopted to identify specific thalamocortical connectivity between the thalamus and 6 cortical regions of interest (i.e., the motor cortex/supplementary motor, the prefrontal cortex, the temporal lobe, the posterior parietal cortex, the somatosensory cortex and the occipital lobe). In LPE patients, regression analysis was subsequently conducted to assess relationships of thalamocortical connectivity with the Premature Ejaculation Diagnostic Tool (PEDT) score and the Intravaginal Ejaculatory Latency Time (IELT). RESULTS: LPE patients had significantly decreased FC between the motor cortex and bilateral ventral thalamus, between the prefrontal cortex and left dorsomedial thalamus, as well as between the temporal cortex and bilateral ventromedial thalamus. In LPE patients, PEDT score was significantly positively associated with the thalamus-posterior parietal cortex FC, and negatively associated with the thalamus-temporal cortex FC, while IELT was positively associated with the thalamus-temporal cortex and thalamus-motor cortex FC. CONCLUSION: These results enrich the imaging evidence for the understanding of the neurobiological mechanisms and/or consequences of LPE.

New behavior therapy in the treatment of acquired premature ejaculation: A comparative study of listening to music. / Nueva terapia conductual en el tratamiento de la eyaculación precoz adquirida: un estudio comparativo de escuchar música.

OBJECTIVES: Premature ejaculation (PE) is one of the most frequently seen causes of sexual dysfunction in males. The aim of this study is to investigate whether the music therapy is effective in the treatment of acquired PE and compare the intravaginal ejaculation latency time (IELT), premature ejaculation diagnostic tool (PEDT), and anxiety scores of patients with acquired PE symptoms that underwent music therapy to patients that were treated with 30 mg dapoxetine. MATERIALS AND METHODS: The study's inclusion criteria was as following: age range from 20-35, married, has regular sexual intercourse, non-smokers, and has no known comorbidities. All participants of the study were with acquired PE based on the International Society for Sexual Medicine criteria. Experimental group (group 1) included 60 patients that were asked to listen to relaxing music and meditate for 45 minutes before the sexual intercourse while continuing their daily routine. This group was selected randomly and prospectively from young healthy individuals. Meanwhile, control group (group 2) included 60 patients who were treated with 30 mg dapoxetine for PE and whose datas were collected from the hospital archive. The patients were evaluated before treatment and re-evaluated (PEDT, IELT, anxiety level) after 60 days. State-Trait Anxiety Inventory was used to assess state and trait anxiety. RESULTS: In both groups, a significant difference (p<0.001) was observed in pre and post-treatment IELT, PEDT, and anxiety scores. Although group 2 showed better improvement in both IELT and PEDT scores, there was no significant difference between two groups. CONCLUSION: Listening to music and other similar anxiety decreasing methods can be a part of treatment plan for PE.

OBJETIVOS: La eyaculación precoz (EP) es una de las causas más frecuentes de disfunción sexual en los hombres. El objetivo de este estudio es investigar si la musicoterapia es eficaz en el tratamiento de la EP adquirida y comparar el tiempo de latencia de la eyaculación intravaginal (IELT), la herramienta de diagnóstico de la eyaculación precoz (PEDT) y las puntuaciones de ansiedad de pacientes con síntomas de EP adquirida que se sometieron a musicoterapia a pacientes que fueron tratados con 30 mg de dapoxetina.MATERIALES Y MÉTODOS: Los criterios de inclusión del estudio fueron los siguientes: rango de edad de 20 a 35 años, casado, tiene relaciones sexuales regulares, no fuma y no tiene comorbilidades conocidas. Todos los participantes del estudio fueron diagnosticados con EP adquirida según los criterios de la Sociedad Internacional de Medicina Sexual. El grupo experimental (grupo 1) incluyó a 60 pacientes a los que se les pidió que escucharan música relajante y meditaran durante 45 minutos antes de la relación sexual mientras continuaban con su rutina diaria. Este grupo se seleccionó de forma aleatoria y prospectiva entre individuos jóvenes sanos. Mientras tanto, el grupo de control (grupo 2) incluyó a 60 pacientes que fueron tratados con 30 mg de dapoxetina para EP y cuyos datos fueron recolectados del archivo del hospital. Los pacientes fueron evaluados antes del tratamiento y reevaluados (PEDT, IELT, nivel de ansiedad) después de 60 días. Se utilizó el Inventario de Ansiedad Estado-Rasgo para evaluar el estado y el rasgo de ansiedad. RESULTADOS: En ambos grupos, se observó una diferencia significativa (p<0,001) en las puntuaciones de IELT, PEDT y ansiedad antes y después del tratamiento. Aunque el grupo 2 mostró una mejora en las puntuaciones de IELT y PEDT, no hubo diferencias significativas entre los dos grupos.CONCLUSIÓN: Escuchar música y otros métodos similares para disminuir la ansiedad puede ser parte del plan de tratamiento para la EP.

Abnormal Thalamic Metabolism in Patients With Lifelong Premature Ejaculation.

BACKGROUND: Although some recent neuroimaging studies have indicated the abnormal brain structure or function in patients with lifelong premature ejaculation (LPE), whether and how the abnormal thalamic function participates in processing sexual behavioral information are still unclear in patients with LPE. AIM: The aim of this study was to assess the changes in the thalamus metabolism and structural integrity in patients with LPE. METHODS: We performed a multimodal magnetic resonance approach in a 3.0 T system, including proton magnetic resonance spectroscopy (1H-MRS), diffusion tensor imaging, and volumetric analysis to detect the differences in thalamic metabolism and structure between 20 patients with LPE and 15 healthy controls. OUTCOMES: We analyzed and correlated the clinical symptoms of the subjects with significant 1H-MRS-based features. Peak areas of N-acetylaspartate, choline, creatine (Cr), and glutamate/glutamine (Glu) were calculated with the LCModel software. RESULTS: Diffusion tensor imaging and volumetric analysis of thalami showed no differences between the 2 groups. On the contrary, 1H-MRS study disclosed that both Glu concentrations and Glu/Cr ratio values in the thalami of patients with LPE were remarkably increased when compared with healthy controls (P < .01 for both variables). In addition, both the intravaginal ejaculatory latency time score and Chinese Index of Sexual Function for Premature Ejaculation-5 score were negatively related to increased Glu concentrations and Glu/Cr ratio values. CLINICAL IMPLICATIONS: Glutamatergic activity changes of thalamus may be an underlying indicator for evaluating sensory conduction efficiency in patients with LPE. STRENGTHS & LIMITATIONS: The present study first found the abnormal thalamic metabolism in patients with LPE and contributed to a better understanding of the LPE etiology. Limitations include a cross-sectional study design with small samples and no examination of other brain areas. CONCLUSION: Our findings show that the increase in glutamatergic activity of thalamus is related to LPE, suggesting that the increased Glu neurotransmission in the thalamus may contribute to the development of premature ejaculation.

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.

[Medication rules of traditional Chinese medicine for the treatment of premature ejaculation: An analysis based on data mining].

OBJECTIVE: To study the medication rules of traditional Chinese medicine (TCM) in the treatment of premature ejaculation. METHODS: We searched the databases of CNKI, Wan Fang, VIP, SinoMed (CBM) and PubMed for studies on the treatment of PE with TCM prescriptions and performed statistical analyses on the data obtained using the TCM inheritance auxiliary platform software. RESULTS: Totally 180 prescriptions were identified, involving 209 TCM drugs. The results of statistical analysis showed that the TCM drugs for the treatment of premature ejaculation were mostly warm, flat or cold in nature, sweet or spicy in taste, and with the kidney, liver and spleen meridian tropisms. The single TCM drugs most commonly used included Lycium barbarum L (Gouqizi), followed by Epimedium brevicornum Maxim (Yinyanghuo), Os draconis (Longgu), Fructus rosae laevigatae (Jinyingzi), and the drugs most frequently used in combination with others in a prescription were Os draconis (Longgu) and Concha ostreae (Muli). Seven newly derived prescriptions were identified in addition. CONCLUSIONS: The compatibility of TCM in the treatment of premature ejaculation is characterized by the combination of the drugs for tonifying the kidney and arresting seminal emission as the main medication strategy, with those for soothing the liver and invigorating the spleen as the adjuvant agents, which has a certain clinical application value.

A Randomized Double-Blind Placebo-Control Study to Assess the Efficacy and Safety of OLNP-05 Versus Placebo for the Treatment of Subjects with Premature Ejaculation.

Premature ejaculation (PE) is one of the foremost sex-related health problems among men. The global occurrence ranges from 20% to 30%, according to various studies. PE has a great impact on the men's quality of life, with deleterious effects such as embarrassment, frustration, and feeling of incompetence. Considering the necessity of treatment of PE, this study was planned to compare the efficacy and safety of OLNP-05 versus placebo for treating subjects suffering from PE. In this randomized clinical study, 60 men with PE were enrolled and randomly assigned to receive either OLNP-05 or placebo one capsule twice daily for a period of 8 weeks. Subjects were evaluated during visits on day 1, day 28, and day 56. Mean change from baseline in intravaginal ejaculatory latency time (IELT), improvement in premature ejaculation profile (PEP), and Clinical Global Impression-Improvement scale (CGI-I) were used to assess the efficacy of treatment. P-value <.05 was considered significant. At the end of the treatment, the improvement in IELT score in the OLNP-05 group was remarkably higher than the placebo. Subjects in the OLNP-05 treatment group also reported significantly greater improvement in PEP subscale score. Majority of OLNP-05-treated subjects were found to be in the "much improved" category as per CGI-I assessment. The result confirms the safety and efficacy of OLNP-05, therefore suggesting that OLNP-05 may be a safe and effective intervention for the management of PE.
