Review
In summary, important events of ejaculation include emission of sperm and the accessory gland fluids into the urethra, simultaneous closure of the bladder neck, and forceful ejaculation of the combined semen through the urethra. Emission and bladder neck closure are primarily alpha-adrenergically mediated thoracolumbar sympathetic reflex events with supraspinal modulation. Ejaculation is a sacralspinal reflex mediated by the pudendal nerve. In stallions, the most common ejaculation disorders are emission and ejaculation failure, and urine contamination of semen. Rare disorders are azoospermia and premature ejaculation. In a large percentage of cases, an ejaculation appears to be a result of musculoskeletal disorders or to be psychogenic in nature rather than attributable to specific ejaculatory dysfunction. Traditional therapeutic approaches for accommodating deficits can extend the breeding life of many stallions. Pharmacologic aids may be useful.

BACKGROUND
We investigated the association between premature ejaculation (PE) and the quality of residential environment from a new perspective to explore the influencing factors of PE, especially in four PE subtypes. We selected 499 adult males to participate in this study from September 2021 to September 2022. The satisfaction of residential environment was assessed by the Perceived Residential Environment Quality Indicators (PREQIs) scale, the control ability over ejaculation was assessed using the premature ejaculation diagnostic tool (PEDT), and their depression was assessed using the self-rating depression scale (SDS).
RESULTS
The Architectural and Town-planning Spaces (ATS), Green Spaces (GS), and Commercial Services (CS) of PE patients (N = 346) were compared with those of control group (N = 153), showed a significant difference (p < .05), for PE patients, the score of ATS was 44.30 ± 12.38, the score of GS was 18.60 ± 6.24, and the score of CS was 20.82 ± 8.20; for control group, which were 40.46 ± 16.21, 20.69 ± 5.71 and 22.90 ± 7.03 respectively. After age was taken into account, ATS had a positive correlation with PEDT score (r = 0.76), whereas GS and CS had a negative correlation (r = -0.87, -0.90); ATS had a positive correlation with SDS (r = 0.96), whereas GS and CS had a negative correlation (r = -0.74, -0.81).
CONCLUSIONS
We discovered that PE patients more likely resided in high-density areas with little green space and subpar commercial services, which might have an adverse effect on their mental health. This study offered a new viewpoint about the influence of residential environment on PE.

BACKGROUND
Premature ejaculation (PE) is the one of the most prevalent male sexual dysfunction, there has not been specific medicine or therapy for the disease. As an effective treatment for premature ejaculation is a behavioral therapy and is widely used worldwide. The purpose of this study is to evaluate the efficacy and safety of behavioral therapy in patients who suffer from PE.
METHOD
We will search all randomized controlled trials (RCTs) from the following electronic databases, by September 30, 2018, such as PubMed, EMBASE, the Cochrane Library, Web of Science database, China Biology Medicine disc (CBM), China National Knowledge Infrastructure (CNKI), China Science and Technology Journal database (VIP), and Wanfang Database. We will also collect clinical trial registries, dissertations, grey literature, reference lists of studies, systematic reviews, and conference abstracts. The primary outcomes include the Intravaginal Ejaculatory Latency Time (IELT). Besides, Premature Ejaculation Diagnostic Tool (PEDT), Arabic index of Premature Ejaculation (AIPE), Index of Premature Ejaculation (IPE) will be the secondary outcomes. Two people will review these articles, extract the data information, and assess the quality of studies separately. RevMan (version 5.3) and EndNote X7 will be used for meta-analysis.
RESULTS
This study will generate a comprehensive review of current evidence of behavioral therapy for premature ejaculation.
CONCLUSION
The study will provide updated evidence to evaluate the efficacy and safety of behavioral therapy for premature ejaculation.
ETHICS AND DISSEMINATION
It is not necessary for this systematic review to acquire an ethical approval. This review will be reported in a peer-reviewed journal.

The Journal of International Medical... Apr 2021To investigate sex hormone and blood lipid levels in patients with lifelong premature ejaculation (LPE) in China.
OBJECTIVE
To investigate sex hormone and blood lipid levels in patients with lifelong premature ejaculation (LPE) in China.
METHODS
Sex hormone and blood lipid levels were measured in 156 patients with LPE and 76 healthy controls. The Premature Ejaculation Diagnostic Tool (PEDT) and Chinese Index of Sexual Function for Premature Ejaculation-5 Questionnaires (CIPE-5) were applied to diagnose and grade LPE.
RESULTS
PEDT and CIPE-5 scores were significantly altered in the LPE group compared with the control group. Free testosterone levels were significantly higher in the LPE group than in the control group. Free testosterone levels were also significantly higher in the mild, moderate, and severe LPE subgroups than in the control group. Total testosterone and prolactin levels tended to be lower in the control group than in the LPE group. Very low-density lipoprotein levels were significantly lower in the LPE group and LPE subgroups than in the control group. Triglyceride levels were highest in controls and decreased with progression of LPE.
CONCLUSIONS
Patients with LPE have higher free testosterone levels and lower very low-density lipoprotein levels than controls. These findings indicate that these factors might be indices for LPE. However, the reasons for these phenomena need to be further investigated.

Meta-Analysis
BACKGROUND
Premature ejaculation is a form of male sexual dysfunction. As people's lifestyle changes and the population ages, the incidence of premature ejaculation continues to increase. Many clinical trials have proven that Chinese medicine has a significant effect in the treatment of premature ejaculation. In this systematic review, we aim to evaluate the effectiveness and safety of Traditional Chinese medicine for premature ejaculation.
METHODS
We will search for PubMed, Cochrane Library, AMED, EMbase, WorldSciNet; Nature, Science online and China Journal Full-text Database (CNKI), China Biomedical Literature CD-ROM Database (CBM), and related randomized controlled trials included in the China Resources Database. The time is limited from the construction of the library to April 2019. We will use the criteria provided by Cochrane 5.1.0 for quality assessment and risk assessment of the included studies, and use the Revman 5.3 and Stata13.0 software for meta-analysis of the effectiveness, recurrence rate, and symptom scores of premature ejaculation.
ETHICS AND DISSEMINATION
This systematic review will evaluate the efficacy and safety of Traditional Chinese medicine for treating premature ejaculation. Because all of the data used in this systematic review and meta-analysis has been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process Trial.

Review
As long as man has breathed, his fascination, pursuit and quest for the perfect sexual experience have remained one of his principal raisons d'être. After thousands of years, millions of words and pictures, and billions of attempts, he still often finds the goal largely unobtainable. Until recently, our understanding of premature ejaculation (PE) was an eclectic mix and homogenization of ancient historical and culturally diverse influences. However, recent basic and clinical research has resulted in a new understanding and a paradigm shift in the way we classify, define, evaluate, diagnose and treat PE.

Premature ejaculation (PE) is a common male sexual disorder. Recent normative data suggests that men with an intravaginal ejaculatory latency time (IELT) of less than 1 minute have "definite" PE, while men with IELTs between 1 and 1.5 minutes have "probable" PE. Although there is insufficient empirical evidence to identify the etiology of PE, there is limited correlational evidence to suggest that men with PE have high levels of sexual anxiety and inherited altered sensitivity of central 5-HT (5-hydroxytryptamine, serotonin) receptors. Pharmacological modulation of the ejaculatory threshold using off-label daily or on-demand selective serotonin re-uptake inhibitors is well tolerated and offers patients a high likelihood of achieving improved ejaculatory control within a few days of initiating treatment, consequential improvements in sexual desire and other sexual domains. Investigational drugs such as the ejaculo-selective serotonin transport inhibitor, dapoxetine represent a major development in sexual medicine. These drugs offer patients the convenience of on-demand dosing, significant improvements in IELT, ejaculatory control and sexual satisfaction with minimal adverse effects.

PURPOSE
This study discusses the treatment of premature ejaculation (PE) using various approaches with the goal of evaluating the methods of diagnosis and treatment of PE in clinical practice in 2014 in South Korea.
MATERIALS AND METHODS
We surveyed 200 urologists and andrologists who treated patients with PE from July 1, 2014 to July 29, 2014 using an online questionnaire. The questionnaire was composed of 4 parts: disease, comorbidities, diagnosis, and treatment. Using the answers to this survey, current trends in the diagnosis and treatment of PE were investigated using weighted averages.
RESULTS
The median number per month of patients who were diagnosed with PE was 14 patients (interquartile range, 7~24). The time to ejaculation necessary for a diagnosis of PE was considered to be <1 minute by 12% of respondents, <2 minutes by 27%, <3 minutes by 28%, <5 minutes by 13%, and 20% stated that diagnosis was based on a patient's subjective complaint. The treatment methods preferred by PE patients were reported to be pharmacological treatment (87%), surgical treatment (9.5%), and behavioral management (3.5%). The treatment methods used by respondents were pharmacological treatment (77%), surgical treatment (15%), and behavioral management (14%). The most commonly used pharmacological treatment was the oral administration of dapoxetine (97%).
CONCLUSIONS
In 2014 in South Korea, various methods were used to diagnose and treat PE. The most commonly used treatment for PE was the oral administration of dapoxetine. It was also found that surgical treatment was applied in some cases.

Premature ejaculation (PE) is the most common male sexual dysfunction. The brain disturbances that cause this disorder remain poorly understood. This study aimed to investigate how the morphology of cortical and subcortical brain structures differed in PE, how these morphologic differences were associated with severity measures of PE, such as intravaginal ejaculatory latency time (IELT), and how these cortical and subcortical structures were causally connected through mediation analysis. Anatomical MRI scans were acquired from 39 male participants, 23 with PE (28.78 ± 4.32 years), and 16 without PE (27.88 ± 3.65 years). We used a subcortical analysis package within FSL to perform subcortical shape segmentation and statistical analysis. The PE group was compared with the normal control (NC) group in the shapes of 15 subcortical structures with general linear models [ < 0.05, family-wise error (FWE)-corrected]. We analyzed the cortical complexity revealed by the gyrification index using the Computational Anatomy Toolbox (CAT12). Vertex-wise shape analyses revealed outward shape deformations (expansions) in the left hippocampus and bilateral thalamus. Gyrification index analyses revealed that the right orbital frontal cortex and the right nucleus accumbens had greater complexity in PE patients. The shape deformations were positively correlated with the IELTs in the NC group, while this relationship was interrupted in the PE group. PE is associated with outward deformations of the subcortical surfaces and more complexity of the cortical structures. These morphological differences may be the basis of the brain functional alterations underlying PE.
