Abstract
Recurrence after drug cessation is the biggest drawback of medical premature ejaculation (PE) treatments. Although these treatments are demonstrated to be safe and effective, most of the PE patients are interested in a more permanent solution. Despite the fact that currently available guidelines do not recommend surgical treatment for PE, some surgical interventions have been commonly performed for many years, especially in the Asian countries. The main purpose of these surgical treatments is to decrease the sensitivity of the glans penis. However, they are associated with irreversible complications such as penile deformity, sensory loss and erectile dysfunction. The aim of this narrative review is to summarize the advantages and disadvantages of various surgical interventions introduced for the treatment of PE. PubMed, Scopus and Web of Science have been utilized to search articles about glans penis augmentation and penile dorsal nerve interventions. A total of 11 articles were included, three articles excluded because they were in non-English languages. Glans penis augmentation offered a less invasive treatment that avoids severe side effects but requires retreatment in time. Selective dorsal neurectomy provided a more invasive but curative treatment alternative. However, more clinical data are necessary before surgical treatment options can be recommended to patients with PE.

Niu C, Wen G, Ventus D, Jern P, Nyman TJ, Li Y, Santtila P. High-intensity interval training (HIIT) and slow breathing interventions alleviate premature ejaculation (PE) symptoms. Int J Clin Health Psychol 2024; 24:100457. [PMID: 38623145 PMCID: PMC11017278 DOI: 10.1016/j.ijchp.2024.100457] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Accepted: 04/02/2024] [Indexed: 04/17/2024] Open
Abstract
Background Physical exercise may alleviate premature ejaculation symptoms, a prevalent male sexual dysfunction linked to a series of negative outcomes for men and their partners. Objective We investigated the effectiveness of high-intensity interval training (HIIT) and slow breathing interventions on premature ejaculation symptoms and their relation to autonomic activity and attention regulation. Method Chinese adult men (N = 76, M = 21.89, SD = 3.32) with premature ejaculation completed one of the two-week interventions in their homes or as participants in a normal breathing control group; they reported their age, height, weight, physical activity level, premature ejaculation symptoms, and attention regulation. In the HIIT group, 26 participants engaged in a 7-minute HIIT each day. In the slow breathing group, 25 participants performed 7-minute slow breathing exercises per day while the 25 participants in the normal breathing group similarly performed normal breathing exercises. All participants measured their heart rate once before and five times (with one-minute intervals) after the intervention. When participants had penile-vaginal sex with their partners, they measured their heart rate once after ejaculation. Results Time × Intervention interaction was significant with lower levels of premature ejaculation symptoms on Days 12, 13, and 14 in the HIIT group (M ± SD = 16.19 ± 3.45, 15.96 ± 3.43, and 15.15 ± 3.62) compared to the normal breathing group (M ± SD = 17.68 ± 3.06, 17.68 ± 3.15, and 17.44 ± 3.25). Higher levels of attention regulation were associated with fewer premature ejaculation symptoms. We also found that a larger increase in heart rate from resting to after sex was associated with fewer premature ejaculation symptoms. Conclusion Compared to the control group, the efficacy of two weeks of HIIT exercise in mitigating PE symptoms suggests its potential as a novel treatment for PE.

Wu C, Huang S, Liu Z, Wang Y, Zhu Y, Zang ZJ. Correlation between serum tryptophan metabolism and treatment efficacy of dapoxetine in patients with premature ejaculation: A pilot study. Andrology 2024. [PMID: 38511846 DOI: 10.1111/andr.13632] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/07/2024] [Revised: 02/20/2024] [Accepted: 03/04/2024] [Indexed: 03/22/2024]
Abstract
INTRODUCTION Primary premature ejaculation (PPE) is a common male neurobiological disorder. Currently, there is consensus that the impairment in central serotonin (5-HT) neurotransmission constitutes a key pathogenic factor in PPE. Selective serotonin reuptake inhibitors (SSRIs) serve as the primary pharmacological intervention; however, a comprehensive elucidation of their mechanism of action remains incomplete. Owing to significant individual variability in efficacy, SSRIs exhibit a high discontinuation rate. Hence, there is an urgent need to address the selection of SSRIs for PPE treatment. OBJECTIVE This study aims to investigate the characteristics of tryptophan (TRP) metabolism in patients with PPE and to assess its influence on the efficacy of SSRIs. METHODS The exploratory study included a total of 16 patients with PPE and 16 control subjects who were healthy men without any sexual dysfunction. Upon enrollment in the study, all participants underwent a thorough medical history review and physical examination. Subsequently, their serum levels of TRP, its metabolites, large neutral amino acids (LNAAs), and metabolite ratios were assessed using a liquid chromatography-mass spectrometry (LC-MS) assay. After a period of 4 weeks of dapoxetine treatment, all patients with PPE underwent reassessment using the Premature Ejaculation Diagnostic Tool (PEDT) score and intravaginal ejaculatory latency time (IELT) test. RESULTS The ratio of serum TRP to other LNAAs (TRP/LNAAs) in patients with PPE was found to be significantly lower compared to the control group (P < 0.05). Conversely, the ratio of kynurenine to TRP (KYN/TRP) was observed to be significantly higher in the PPE patients compared to the control group (P < 0.05). Including the serum TRP/LNAAs ratio and KYN/TRP ratio in the prediction model yielded the highest prediction efficiency for PPE. There was a significant negative correlation between the ratio of TRP/LNAAs before the treatment and the IELT after 4 weeks of the treatment. Additionally, there was a significant positive correlation observed between the ratio of TRP/LNAAs before the treatment and the PEDT score after 4 weeks of the treatment. CONCLUSIONS This study demonstrates that the reduction in the TRP/LNAAs ratio and the elevation of the KYN/TRP ratio are significant characteristics associated with PPE. These findings suggest that diminished tryptophan availability in the brain and the activation of the kynurenine (KYN) pathway may play a role in the pathogenesis of PPE. The TRP/LNAAs ratio has potential as a reliable indicator of central serotonin (5-HT) levels. Considering the TRP/LNAAs ratio when selecting SSRIs for the treatment of PPE may enhance the response rate of this medication.

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. Andrology 2024; 12:247-258. [PMID: 36748824 DOI: 10.1111/andr.13403] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 12/30/2022] [Accepted: 01/27/2023] [Indexed: 02/08/2023]
Abstract
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.

Abstract
AIM We aimed to determine the effectiveness of penis-root masturbation (PRM), a newly defined behavioral therapy (BT) technique, in patients with unsuccessful medical treatment due to premature ejaculation (PE). MATERIAL AND METHODS The study included 35 patients aged 25-43 years, who were diagnosed with lifelong PE. Patients and their partners were informed about the PRM technique and asked to practice PRM three times a week for three months, with or without sexual intercourse. The patients' Premature Ejaculation Diagnostic Tool (PEDT) scores and intravaginal ejaculatory latency time (IELT) were recorded and compared before PRM training (T0) and at the third (T3) month after the start of PRM training. RESULTS The mean±SD PEDT scores were 16.26±1.94 at T0, 10.63±1.14 at T3. When compared to T0, the PEDT values at T3 were significantly lower (P=0.021). In terms of IELT, the mean T3 values (192.43±56.71) were significantly longer (P=0.035) than at T0 (50.43±13.84seconds). CONCLUSION PRM BT shows promise for lifelong PE patients who do not benefit from or discontinue to pharmacotherapy. Larger prospective trials are required to confirm these findings.

A new approach to 'on-demand' treatment of lifelong premature ejaculation by treatment with a combination of a 5-HT 1A receptor antagonist and SSRI in rats. Front Neurosci 2023; 17:1224959. [PMID: 37781259 PMCID: PMC10534979 DOI: 10.3389/fnins.2023.1224959] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Accepted: 08/16/2023] [Indexed: 10/03/2023] Open
Abstract
Lifelong premature ejaculation (PE) in men lacks an adequate on-demand pharmacological treatment. Although selective serotonin reuptake inhibitors (SSRIs) are used for PE they only work after chronic treatment, or if used on-demand, less adequately than chronic SSRI treatment. It has been shown that the addition of a behaviorally silent 5-HT1A-receptor antagonist to an SSRI can generate acute inhibitory effects on male rat sexual behavior. Atlas987 is a selective 5-HT1A-receptor antagonist with equal potency to displace agonist and antagonist binding to pre- and post-synaptic 5-HT1A receptors in rat and human brain. To investigate whether Atlas987 together with the SSRI paroxetine, a combination called Enduro, induces acute inhibitory effects on male rat sexual behavior, we tested Enduro in Wistar rats in a dose-dependent manner. We first tested the 5-HT1A receptor antagonist Atlas987 in 8-OH-DPAT induced serotonergic behavior in rats. Second, we tested Enduro in a dose-dependent manner in male sexual behavior. Third, we tested the effective time window of Enduro's action, and lastly, we measured the plasma levels of Atlas987 and paroxetine over an 8-h period. Results showed that Enduro acutely and dose-dependently reduced the number of ejaculations and increased the ejaculation latencies. The behavioral pattern induced reflected a specific effect on sexual behavior excluding non-specific effects like sedation or sensoric-motoric disturbances. The time-window of activity of Enduro showed that this sexual inhibitory activity was at least found in a 1-4 h' time window after administration. Plasma levels showed that in this time frame both Atlas987 and paroxetine are present. In conclusion, in rats, Enduro is successful in acutely inhibiting sexual behavior. These results may be therapeutically attractive as "on demand" treatment for life-long premature ejaculation in men.

Abstract
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.

Abstract
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.

Shechter A, Mondaini N, Serefoglu EC, Gollan T, Deutsch F, Appel B, Gruenwald I. A novel on-demand therapy for lifelong premature ejaculation using a miniature transperineal electrical stimulator-the vPatch: an as-treated analysis. J Sex Med 2023; 20:22-29. [PMID: 36897239 DOI: 10.1093/jsxmed/qdac012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 10/04/2022] [Accepted: 10/09/2022] [Indexed: 01/14/2023]
Abstract
BACKGROUND While premature ejaculation (PE) is a common and disturbing sexual dysfunction in men, current available treatment modalities have limited efficacy and low treatment adherence. AIM To assess the feasibility, safety, and efficacy of the vPatch, a miniaturized on-demand perineal transcutaneous electrical stimulation device for treating PE. METHODS This prospective bicenter international first-in-human clinical study consisted of 2 arms, was sham controlled, and had a randomized double-blind design. In terms of statistical power calculation, 59 patients aged 21 to 56 years (mean ± SD, 39.8 ± 9.28) with lifelong PE were included. During the initial visit, intravaginal ejaculatory latency time (IELT) was measured over a 2-week run-in period. Eligibility was confirmed in visit 2, based on IELT values, medical and sexual history, and patients' individualized sensory and motor activation thresholds during perineal stimulation with the vPatch. Patients were randomized to the active (vPatch) and sham device groups in a 2:1 ratio, respectively. The vPatch device's safety profile was determined by comparing the incidence of treatment-emergent adverse events. During visit 3, IELTs, Clinical Global Impression of Change scores, and Premature Ejaculation Profile questionnaire outcomes were recorded. Primary end points assessed vPatch device efficacy as mean change in geometric mean IELT; each person was compared with himself, with and without the device, and the sham group was compared with the active group. OUTCOMES Outcomes included changes in IELT and Premature Ejaculation Profile before and after treatment, last visit Clinical Global Impression of Change scores, and vPatch safety profile. RESULTS Of 59 patients, 51 completed the study: 34 in the active group and 17 in the sham group. The baseline geometric mean IELT significantly increased from 67 to 123 seconds (P < .01) in the active group, as compared with an insignificant increase from 63 to 81 seconds (P = .17) in the sham group. The increase in mean IELT in the active group was significantly higher than in the sham group (56 vs 18 seconds, P = .01). IELT significantly increased by 3.1 times in the active vs sham group. The mean ratio of fold change (active:sham) was 1.4, significantly different from 1.0 (P = .02). No serious adverse events were reported. CLINICAL IMPLICATIONS Therapeutic use of the vPatch during coitus may become an on-demand, noninvasive, and drug-free treatment for PE. STRENGTHS AND LIMITATIONS To our knowledge, this is the first rigorous study investigating whether transcutaneous electrical stimulation during coitus could improve the symptoms of men with lifelong PE. The study is limited by the small number of patients, the exclusion of patients with acquired PE, the short-term follow up, and the use of a device based on a theoretic mechanism of action. CONCLUSION We demonstrated the possibility to treat lifelong PE by prolonging coitus on demand, using electric stimulation of ejaculation muscles with the vPatch.Clinical trial registration: NCT03942367 (ClinicalTrials.gov).

The Men’s Training Cup Keep Training: a masturbation aid improves intravaginal ejaculatory latency time and Erection Hardness Score in patients who are unable to delay ejaculation. Sex Med 2023; 11:qfac010. [PMID: 37007846 PMCID: PMC10065175 DOI: 10.1093/sexmed/qfac010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2022] [Revised: 09/26/2022] [Accepted: 11/11/2022] [Indexed: 01/19/2023] Open
Abstract
Abstract
Introduction
Premature ejaculation (PE) has negative personal consequences, such as distress, bother, frustration, and/or the avoidance of sexual intimacy. In Japan, no oral drugs or devices are approved or used clinically to treat PE. The Men’s Training Cup Keep Training (MTCK), a masturbation aid, was developed for PE. MTCK offers 5 grades of tightness and strength.
Aim
We aimed to investigate the efficacy of the MTCK in patients who are unable to delay ejaculation.
Methods
Inclusion criteria were 20- to 60-year-old men feeling distressed and frustrated by PE and who had the same sexual partners throughout the study period. Exclusion criteria were neurologic disease and uncontrolled diabetes mellitus, as well as the use of antidepressants, α-blockers, and 5α-reductase inhibitors. The protocol comprised an 8-week training period with the MTCK from level 1 to level 5, with each level used twice before moving to the next level.
Outcome Measures
The main outcome measure was the extension of intravaginal ejaculation latency time (IELT). The secondary outcome measures were score improvements on the Premature Ejaculation Diagnostic Tool, Sexual Health Inventory for Men, Erection Hardness Score, and Difficulty in Performing Sexual Intercourse Questionnaire–5.
Results
We enrolled 37 patients, and after 19 patients withdrew, 18 concluded the study without experiencing any adverse events. The mean patient age was 39.9 years. Geometric IELT after the 8-week training with the MTCK increased significantly (mean ± SE; 232.10 ± 72.16 seconds) vs baseline (103.91 ± 50.61 seconds, P = .006). Mean scores on the Premature Ejaculation Diagnostic Tool, Difficulty in Performing Sexual Intercourse Questionnaire–5, and Erection Hardness Score after 8-week training improved significantly vs the baseline values. The mean score on the Sexual Health Inventory for Men did not improve significantly after the 8-week training, but domain 1 did significantly improve after 8 weeks of MTCK use.
Clinical Implications
The MTCK may be one possible treatment option for patients who are unable to delay ejaculation.
Strengths and Limitations
This is the first study to show that the MTCK is effective for patients who are unable to delay ejaculation. A major limitation is that the present study was not strictly limited to an IELT <3 minutes.
Conclusions
The MTCK may offer benefits not only for delay of ejaculation but also for erectile function.

Abstract
Premature ejaculation (PE) is a prevalent male sexual dysfunction. Current standard treatment regimens include behavioural therapies, topical anaesthetics, dapoxetine and other selective serotonin reuptake inhibitors (SSRIs). Most of the pharmacotherapeutic options target neurotransmitters (such as serotonin and oxytocin) that have a role in the ejaculation mechanism. However, these treatments are mildly effective and only provide a temporary delay in the ejaculation latency time, and PE recurs when the treatment is stopped. Thus, a treatment for PE is urgently needed and research is ongoing to find the ideal PE therapy. The efficacy and safety of topical anaesthetics and SSRIs in delaying ejaculation have been confirmed in many well-designed controlled trials. Both preclinical and clinical studies on new-generation SSRIs are ongoing. Moreover, promising results came from clinical trials in which the efficacy of on-demand PE therapies targeting neurotransmitters other than serotonin, such as α1-adrenoceptor antagonists and oxytocin antagonists, was assessed. Surgical intervention and neuromodulation have been proposed as potential treatment options for PE; however, current PE guidelines do not recommend these treatments owing to safety concerns.

Comparison of fluoxetine with other selective serotonin reuptake inhibitors in the treatment of premature ejaculation: A systematic review and meta-analysis. Andrologia 2022; 54:e14500. [PMID: 35760074 DOI: 10.1111/and.14500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 05/18/2022] [Accepted: 05/26/2022] [Indexed: 11/29/2022] Open
Abstract
The primary goal of this systematic review and meta-analysis was to compare the efficacy and safety of fluoxetine with other oral pharmaceuticals in the treatment of premature ejaculation (PE). We searched through databases including CNKI, PubMed, EMBASE and Cochrane to find research published up to 31 March 2022. PROSPERO was used to pre-register this meta-analysis (registration number CRD42022315459). Two separate writers extracted relevant details from all of the papers included in the study. To analyse the quality of literature publishing, we used the Cochrane risk of bias tool. The severity of premature ejaculation was determined using intravaginal ejaculatory latency time (IELT), and the effectiveness and safety of pharmacological interventions were determined using standardized mean difference (SMD) and risk ratio (RR) values with matching 95% confidence level intervals (95% CIs). Our meta-analysis includes a total of ten trials to investigate into the differences in treatment efficacy and safety between fluoxetine and other medicines. The findings revealed that fluoxetine was more effective than placebo in treating PE, whereas sertraline and paroxetine were more effective than fluoxetine (p < 0.05). The side effects of the medications were not significantly different, and they were all acceptable. The results of the sensitivity analysis were unaffected by the removal of any of the articles. There was no evidence of bias in the media. This meta-analysis examined the differences in efficacy and safety between fluoxetine and other oral medications and can be used by clinicians in the treatment of PE.

Abstract
The FDA created the Tainted Dietary Supplement Database in 2007 to identify dietary supplements adulterated with active pharmaceutical ingredients (APIs). This article compares the determination of API adulteration in dietary supplement from the 10-year time-period of 2007-2016 to the most recent 5-year period of 2017-2021. From 2007 through 2021, 1,068 unique products have been found to be adulterated with APIs. Sexual enhancement and weight loss dietary supplements are the most common products adulterated with APIs. Phosphodiesterase-5 inhibitors are commonly included in sexual enhancement dietary supplements and a single product can include up to five APIs. Sibutramine, a drug removed from the market due to cardiovascular adverse events, is the most included adulterant API in weight loss products although sibutramine analogues, phenolphthalein (which was removed from the U.S. market for cancer risk), and fluoxetine have also been included. While muscle building dietary supplements were commonly adulterated before 2016, since 2017 no additional adulterated products have been identified. The lack of disclosure of APIs in dietary supplements, circumventing the normal procedure with clinician oversight of prescription drug use, and the use of APIs that are banned by the FDA or used in combinations that were never studied is an important health risk for consumers.

Abstract
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.

Abstract
A new line of treatment for premature ejaculation (PE) based on the use of masturbation aid device in combination with behavioral techniques has emerged in recent years. We report a multicenter randomized clinical trial with a parallel group design to determine the effectiveness of an electronic device called Myhixel I© in the treatment of PE. Forty patients who met the criteria for the diagnosis of lifelong PE, were assigned to two treatment groups completed the Sphincter control training (SCT) program in eight weeks. The only difference between groups was the use of the device. The main measure was the “fold increase” (FI) of the intravaginal ejaculatory latency time (IELT). The geometric means of IELT show, at the end of the treatment at week 8, a superiority of the device group. The mean FI 4.27 (SD 2.59) at the end of treatment for the device group was clearly higher than obtained in the previous clinical trial, in which a specific medical device was not used. No side effects were observed and it required little therapeutic input and no partner involvement. The SCT program in combination with the Myhixel I© is an effective treatment for PE.

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

Abstract
Topical anaesthetics are considered a first-line therapy option in men with premature ejaculation (PE). A cross-sectional retrospective analysis was performed to evaluate the real-life use of the eutectic mixture of prilocaine/lidocaine spray (FORTACIN™) in a cohort of 198 white-European men who had been consecutively and prospectively seen at a single tertiary-referral andrology centre for self-reported PE and naive for previous PE treatments. Descriptive statistics was used to describe the whole cohort and the paired t-test was applied to investigate potential differences throughout a 12-month follow-up (baseline, 1, 3, 6 and 12 months). Overall, mean (SD) age was 37 (6.5) years. Of all, lifelong, acquired and subjective PE were reported in 101 (51%), 59 (29.8%) and 38 (19.2%) patients at baseline, respectively. FORTACIN™ use increased up to 6 months, with 184 (92.9%) and 128 (66.4%) men who had tried and regularly used the compound, respectively. At 12-month follow-up, 53 (26.8%) men reported a regular use of the compound. Mean Premature Ejaculation Diagnostic Tool score significantly decreased at 6 and 12 months compared to baseline (all p < 0.05). Conversely, mean IELT significantly improved at 6-month follow-up compared to baseline (all p ≤ 0.04). Overall, FORTACIN™ emerged to be a safe and effective treatment option in PE patients of various types, with almost one fourth of patients still under treatment after 12 months. Timing and dosing of the drug can deserve to be adjusted according to patient's needs and their sexual ecology.

Topical Treatment of Premature Ejaculation: The Rise of Anesthetic Spray Formulations? URO 2021. [DOI: 10.3390/uro1010005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/17/2022]
Abstract
Topical anesthetics are one of the first line therapeutical options for men with premature ejaculation (PE). Real-life PE management often involves a range of interventions including systemic drug treatments (such as off-label and on-label selective serotonin reuptake inhibitors (SSRIs), tricyclic antidepressants, phosphodiesterase-5 inhibitors (PDE5Is)), topical anesthetic creams and sprays, and behavioral approaches. Among them, on-demand dapoxetine and lidocaine/prilocaine spray formulations are the only approved treatment options for lifelong PE. The earliest strategy to treat PE was based on the use of topical anesthetic agents. The rationale behind the use of anesthetics is that by reducing the glans penis sensitivity, the spinal and cerebral input of sexual arousal impulses may also be reduced. Oral SSRI proved to be effective to treat PE, but their high rate of side effects limit treatment adherence and both short and long term follow up data are lacking. Conversely, topical anesthetics have proved to increase ejaculatory latency, control, and sexual satisfaction in couple affected by PE with limited rates of adverse events. In this context, we aimed to perform a narrative review to summarize the most recent findings regarding the use of topical treatments for PE.

Abstract
Purpose To determine the compliance rate with testosterone replacement therapy (TRT) in patients with testosterone deficiency syndrome (TDS), we evaluated the treatment continuation rate and the reasons for discontinuation of initial treatment according to each formulations and patient characteristics. Materials and Methods Among men over 40 years of age who were diagnosed with TDS and then underwent TRT, their medical records were retrospectively analyzed for those who were followed up for more than 10 years. Results A total of 640 patients were included in the analysis. It was found that 75.9% of patients continued treatment for 1 year after starting. Patients treated with 1,000 mg of testosterone undecanoate injection had the highest treatment rate. Inconvenience of medication was the most common reason for discontinuing treatment, followed by cost, concern about side effects, lack of efficacy, and symptom recovery. The reasons for discontinuing treatment differed according to the xlink:type of formulations, and the longest continuous treatment period in all patients was 15.4±7.6 months on average. The treatment continuation rate tended to be high in patients with low serum total testosterone before starting treatment, in patients with severe erectile dysfunction, and in patients using phosphodiesterase-5 (PDE5) inhibitors. Conclusions Among the various formulations of TDS, testosterone undecanoate injection (1,000 mg) had the highest compliance rate. In addition, it was found that the reasons for discontinuation of treatment varied according to the characteristics of each formulation.

Pharmaceutics 2020; 12:pharmaceutics12121187. [PMID: 33297307 PMCID: PMC7762256 DOI: 10.3390/pharmaceutics12121187] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2020] [Revised: 11/24/2020] [Accepted: 12/02/2020] [Indexed: 01/23/2023] Open
Abstract
The study aimed at developing a liquisolid tablet (LST) containing tadalafil (TDL) and dapoxetine (DPX) with improved bioavailability as a potential therapy for male sexual dysfunction. A mixture of nonvolatile solvents, namely PEG 200 and Labrasol®, was utilized to prepare LSTs that were assessed for their quality characteristics. The Box–Behnken design (BBD) was employed to statistically explore the effect of the formulation factors on the quality attributes of LSTs. Furthermore, an in vivo pharmacokinetic study was carried out for the optimized LST in comparison with the marketed tablets on healthy human volunteers. The optimized LST revealed acceptable quality limits with enhanced dissolution for both APIs. The pharmacokinetic parameters after oral administration of the optimized LST indicated that the Cmax of TDL in LSTs was 122.61 ng/mL within 2h compared to the marketed tablets, which reached 91.72 ng/mL after 3 h, indicating the faster onset of action. The AUC was improved for TDL in LST (4484.953 vs. 2994.611 ng/mL∙h in the marketed tablet) and DPX in LST (919.633 vs. 794.699 ng/mL∙h in the marketed tablet). This enhancement in bioavailability potentially minimizes the associated side effects and improves the treatment of male sexual dysfunction, particularly for diabetic patients.

Abstract
INTRODUCTION Smartphone-delivered healthcare interventions allow patients to access services on demand when needed, improving motivation and compliance. However, the use of mobile health apps has been scarcely explored in sexual medicine. AIM To evaluate the effects of integrating psychological treatment for premature ejaculation (PE) with a mobile coaching app that offers therapeutic exercises on the patient's smartphone. METHODS This study comprised 35 heterosexual men with primary psychogenic PE (mean age 34 years, standard deviation = 9.15). All patients entered a cycle of 15 sessions of psychodynamic psychotherapy integrating behavioral therapy, each lasting about 45 minutes. The patients were randomly assigned to 2 groups, each of which performed daily homework exercises (physiotherapy exercises for reinforcing the pelvic floor muscles and cognitive exercises for distancing from sexual failure.) The first group (15 patients) received verbal and printed instructions only (treatment as usual-TAU), whereas the second group (17 patients) experienced the exercises with guidance from the mobile app (app). In both groups, the exercises started after the seventh session. Patients were advised to perform the exercises 3 times a day for 3 months. MAIN OUTCOME MEASURES The primary outcome measures were the Premature Ejaculation Diagnostic Tool and the Premature Ejaculation Profile. RESULTS Analysis of the data revealed significant pre-post improvements in Premature Ejaculation Diagnostic Tool and Premature Ejaculation Profile scores for the app group compared with those of the TAU group (P < .01). The frequency of patients with no-PE condition for the app group after treatment was significantly higher than the frequency of patients with no-PE condition for the TAU group (P < .001). CONCLUSION Results suggest that a mobile coaching app performs better than TAU in improving both the behavioral skills of ejaculatory delay and sexual self-confidence within a psychological treatment for PE. Future studies should collect follow-up data and explore the potential of mobile coaching apps in combined pharmacotherapy and psychotherapy interventions. Optale G, Burigat S, Chittaro L. et al.

Abstract
INTRODUCTION Premature ejaculation (PE) represents the most prevalent male sexual issue. Before beginning treatment, it is essential to discuss the patient's expectations thoroughly. METHODS Herein, we report the results of an expert panel discussion about perceptions, expectations, preferences, and attitudes towards PE, its diagnosis and treatment. The panel took place in October 2019 and involved 30 Italian urologists experienced in the management of male sexual dysfunction. It aimed at investigating physicians' points of view about selected aspects of PE management which emerged during the counselling of PE patients over the previous two years. Treatment-related questions were mainly focused on topical treatment with Fortacin™. RESULTS Overall, 83.3% of those interviewed declared that most of their patients perceive PE as a bother rather than a disease. The percentage of urologists interviewed perceived that improved subjective control over ejaculation and prolonged intravaginal ejaculatory latency time (IELT) as the main benefit expected by the majority of their patients was 56.5% and 10%, respectively. Eighty percent of urologists reported on-demand regimen as the dosage modality preferred by the majority of their patients and half of them reported the topical route to be the way of administration preferred in most cases. Moreover, 73.3% of urologists reported that adherence to treatment was higher in patients undergoing topical treatment. Finally, 80% of urologists perceived Fortacin to be efficacious in patients with acquired PE and 70% of them perceived its efficacy to be independent from IELT. DISCUSSION Most patients perceive PE as a bother rather than a disease and mainly advocate an improved control over ejaculation. Fortacin is perceived as efficacious in patients with acquired PE, and independent from IELT.

Abstract
Premature ejaculation (PE) is associated with decreased quality of life, lower confidence and self-esteem, and higher levels of depression, anxiety, and interpersonal difficulties. Here we investigated the effectiveness of vibrator-assisted start-stop exercises for treatment of PE, and whether the treatment effect could be enhanced by an additional psychobehavioral intervention. Fifty participants with a mean age of 41.7 years were included and randomized into two treatment groups and a waiting list control group. Participants were instructed to perform start-stop exercises while stimulating the penis with a purpose-made vibrator, 3 times a week for 6 weeks. Additionally, participants in one of the treatment groups received additional psychoeducation and performed mindfulness meditation-based body scan exercises three times a week. Data were gathered through online questionnaires before and after treatment, as well as 3 and 6 months after treatment. The interventions reduced PE symptoms with large effect sizes (partial η2 = .20 across the three groups, d [95% CI] = 1.05 [.27, 1.82] and 1.07 [.32, 1.82] for treatment groups compared to waiting list control group). The additional psychobehavioral intervention did not further reduce PE symptoms, but did decrease PE-associated negative symptoms such as levels of sexual distress, anxiety, and depression. No side effects were reported. Vibrator-assisted start-stop exercises can be offered as an adequate treatment option for PE.

Abstract
OBJECTIVE Premature ejaculation (PE) is regarded as one of the most common male sexual dysfunctions. This review introduced several pharmaceutical and surgical methods for the management of PE. The definition, etiology, behavioral, and psychological therapy of PE were also discussed. DATA SOURCES "Premature," "ejaculation," or "sexual dysfuction" were used as the medical subject headings (MeSH) to obtain relevant articles before June 2019 on Pubmed, Google Scholar and CNKI. Most articles used were written in English and several Chinese articles were also cited. STUDY SELECTION Full-text articles of retrospective/prospective/randomized controlled trials were analyzed. Animal experiments and letters were excluded. RESULTS There are four PE sub-types: lifelong PE, acquired PE, natural variable PE, and subjective PE. Behavioral therapy, psychotherapy, medication, topical anesthetics, and surgery are currently used for the treatment of PE. However, all the above treatments have limitations. Therefore, novel ways should be investigated to more efficiently control PE. CONCLUSIONS The pharmaceutical therapy that is currently being used in clinical practice for the management of PE is still the main choice globally due to its good efficacy. Surgery may be a choice for patients who are resistant to medication. However, it should be performed cautiously.

Abstract
Premature Ejaculation (PE) is a very common and disturbing sexual dysfunction in men. Currently available treatment modalities are associated with limited efficacy and low treatment adherence. In this prospective, single-blinded, self-controlled study, we evaluated the efficacy and safety of transcutaneous electrical stimulation (TES) for the treatment of (PE). We included 23 patients aged 20-60 (mean: 38.7) with lifelong PE. On the first visit, we delivered either TES or sham treatment to the perineum, based on the enrollment order. For stimulation, we used a commercial neuromuscular electrical stimulation device. The patients were invited for the second visit after at least 7 days for receiving the alternating treatment. During the treatment sessions, the patients were left alone in a privet silent room to masturbate and a stopwatch was used to measure their masturbation ejaculatory latency time (MELT). The patients also filled-out safety questionnaires after each visit and on each of the 3 following days. Of the 20 patients who completed the study, 17 (85%) experienced prolonged MELT under TES compared with the sham treatment. Mean MELT values increased 3.5-folds under TES (p = 0.0009). We demonstrated a significant increase in MELT in lifelong PE patients using TES. This therapeutic option may have the potential to become an on-demand treatment option for PE. Future studies with wireless devices are needed to confirm the efficacy and safety of this treatment concept during intercourse.

Abstract
Background The aim of this study was to assess the efficacy and safety of “on-demand” dapoxetine in the treatment of premature ejaculation (PE). Material/Methods We performed a meta-analysis of intravaginal ejaculatory latency time (IELT), patient-reported global impression of change (PGIC), perceived control over ejaculation (PCOE), and drug-related adverse effects (AEs). We searched Medline, PubMed, Embase, CNKI, Wanfang, and VIP databases up to May 30, 2018 with the following search terms: “dapoxetine” or “SSRIs” and “premature ejaculation” or “sexual dysfunction”. Results Our analysis included 11 RCTs (8521 cases and 4338 controls). We found that IELT, PGIC, and PCOE in PE patients with “on-demand” dapoxetine were significantly higher than in the control group, and we observed higher proportions in 60 mg vs. 30 mg dapoxetine. The AEs were mild and tolerable. Conclusions “On-demand” dapoxetine is effective and safe for patients with PE, and a dose of 60 mg may be more effective than 30 mg.

Abstract
Introduction Current evidence suggests that Cognitive Behavioral therapy (CBT) has a limited role in the contemporary management of premature ejaculation (PE). Aim The aim of this study was to determine the efficacy of a new CBT for the PE called Sphincter Control Training (SCT) in combination with a masturbation aid device. Methods The present study included 35 patients’ that met diagnostic criteria for PE including intravaginal ejaculatory latency time (IELT) of ≤2 minutes and had a Premature Ejaculation Diagnostic Tool (PEDT) score ≥11. Participants completed all phases of a randomized controlled clinical study with a parallel group design, which was approved by the Ethical Committee of the Hospital Morales Meseguer of Murcia (Spain).The two treatment groups completed SCT over 7 weeks. The SCT consists of four different exercises and an educational session. Its objective is to provide patients with greater knowledge, awareness, and control of the external urethral sphincter. The only difference between groups was the use of a masturbation aid device called Flip Zero (TFZ-001) from the Japanese company Tenga Co., Ltd. Outcomes The main measure was the "fold increase" (FI) of the IELT, which was calculated using the geometric mean pre-treatment and post-treatment. In addition, Premature Ejaculation Profile PE was used as a secondary measure. Results The geometric mean of the measurements corresponding to the 7 weeks of treatment was calculated, and both groups were compared by means of an ANCOVA test, finding a statistically significant difference (F: 10.51, 1; p = .003) in the increase experienced by subjects in the group with the device (GWD) mean = 166.63, SD = 106.54) compared with that experienced by subjects in the group without device (GWtD) (mean = 86.99, SD = 59.98).Using Student's t-test, the Fold increase (FI) corresponding to both groups were compared. The results showed statistically significant differences (p = .008) between the measurements corresponding to the GWtD (1.38 (0.50)) and those relative to the GWD (2.69 (1.81)) Clinical implications The FI in the GWD at the end of the trial allow us to consider this new CBT as a potential and viable PE treatment alternative. No side effects were observed in either treatment group and it required little therapeutic input and no partner involvement. Strengths & limitations The main limitation of this study is the lack of a 3- to 6-month follow-up of the treatment and placebo control. Conclusions This SCT exercise program combined with the use of a masturbation device shows promise because has numerous advantages in relation to current recommended treatments in patients with PE.

Abstract
To evaluate the overall treatment benefits of premature ejaculation desensitisation therapy combined with 30 mg dapoxetine hydrochloride treatment on patients with primary premature ejaculation (PPE). Ninety-nine PPE patients were randomly divided into two groups at the ratio of 2:1. Sixty-six PPE patients received premature ejaculation desensitisation therapy accomplished by Weili Automatic Semen Collection-Penis Erection Detection and Analysis workstation (WLJY-2008) combined with 30 mg dapoxetine hydrochloride treatment (DTCD group), and another 33 patients received 30 mg dapoxetine hydrochloride-only treatment (DO group). Intravaginal ejaculation latency time (IELT) and premature ejaculation profile (PEP) were recorded before and during the treatment, and clinical global impression of change (CGIC) in PPE was recorded at the fourth week and the end of the treatment and the items. In both groups were significantly improved (p < 0.0001) in IELT, PEP and CGIC for premature ejaculation compared with baseline, and DTCD treatment showed a more significant improvement on PPE patients in the items compared with DO treatment (p < 0.05). Thus, premature ejaculation desensitisation combined with dapoxetine therapy may be a better choice for improving premature ejaculation with PPE.

Abstract
Premature ejaculation (PE) and erectile dysfunction (ED) are the most prevalent sexual disorders in men. ED is commonly reported among patients with PE. Although recent guidelines recommend to treat ED first in men with both PE and ED, this recommendation is not based on evidence and there are limited data about the efficacy and safety of dapoxetine/sildenafil combination therapy for these patients. The aim of this study is to evaluate the clinical efficacy and safety of the dapoxetine/sildenafil combination (Dapoxil® 30/50 mg film-coated tablet) in the treatment of patients with PE and concomitant ED. In a single-center, single-arm, open-label clinical study conducted between October 2016 and September 2017, 74 patients with lifelong or acquired PE and ED were included. All patients were instructed to record their intravaginal ejaculatory latency time (IELT) with a stopwatch for 4 weeks. After the screening, they were requested to complete Premature Ejaculation Diagnostic Tool (PEDT), Premature Ejaculation Profile (PEP), and International Index of Erectile Function-Erectile Function (IIEF-EF) questionnaires before the treatment. The patients received on demand Dapoxil® 1-3 h before sexual intercourse for the next 4 weeks (2 days a week and no more than once a day). The patients were also assessed with global impression of change (GIC) question for the treatment satisfaction and the side effects were recorded. The study was completed with 53 patients (53/74, 71.62%). Mean age of the patients was 45.32 ± 10.05 years. At the end of the 4-week treatment period, the geometric mean IELT of the patients significantly increased (from 22.72 ± 15.16 to 68.25 ± 82.33 s; p < 0.001). Similarly, significant improvements were observed in the mean PEP index score (0.86 ± 0.72 vs. 2.36 ± 1.13; p < 0.001) and mean IIEF-EF domain score (13.17 ± 3.33 vs. 24.60 ± 3.96; p < 0.001). According to the GIC results, 81.13% of the patients were satisfied with the treatment. Non-serious adverse events occurred in 10 patients (18.87%) and 4 (7.55%) of these patients dropped out of the treatment. The most common adverse events were headache, palpitation, and flushing. The dapoxetine/sildenafil combination therapy significantly improves the IELT values and patient reported outcome measures of PE patients who also suffer from ED. Although several side effects were reported, these were mild and transient.

Abstract
Premature ejaculation remains a difficult condition to manage for patients, their partners, and the clinician. Whilst prevalence rates are estimated to be 20-40%, determining a diagnosis of premature ejaculation is difficult, as the definition remains both subjective and ill-defined in the clinical context. As our understanding of the ejaculatory pathway has improved, new opportunities to treat the condition have evolved with mixed results. In this review, we explore some of these controversies surrounding the aetiology, diagnosis, and treatment of this condition and discuss potential novel therapeutic options.

Transcutaneous neuromuscular electrical stimulation may be beneficial in the treatment of premature ejaculation. Med Hypotheses 2017; 109:181-183.

Abstract
Approximately 20-30% of sexually active men suffer from Premature Ejaculation (PE), but the pathophysiology still remains unclear and the current available treatments for PE are unsatisfying. Considering the role of rhythmic bulbospongiosus and ischiocavernosus Muscles contractions on the ejaculatory reflex, we hypothesize that weakening this muscles via inhibiting it's contractions by Application of Neuromuscular Electrical Stimulation prior to the planned sexual activity, may have a beneficial effect in the treatment of PE. Using miniaturized perineal on-demand stimulation device, in a home setting during sexual intercourse may become the first line of treatment for PE.

Abstract
Premature ejaculation (PE), delayed ejaculation (DE), anejaculation (AE) and retrograde ejaculation (RE) are four main ejaculatory disorders (EjDs) observed in clinical practice. Despite their high prevalence, EjDs remain underdiagnosed and undertreated. Primary care physicians should incorporate the discussion of sexual health topics into routine visits to facilitate EjD diagnosis and treatment. Because the causes of EjDs are multifactorial, the management of EjDs is etiology-specific and may require a holistic approach. Dapoxetine, a selective serotonin reuptake inhibitor, is the only drug approved for on-demand treatment of lifelong and acquired PE. In clinical practice, scheduled follow-up visits, risk factor treatment, appropriate dose escalation, adequate sexual attempts, patient education, and partner involvement are critical factors responsible for optimal overall management of PE and dapoxetine treatment outcomes.
