Introduction: This study explores the impact of childhood sexual assault (CSA) on men's sexual function. There is limited understanding on the impact of CSA perpetrated against boys on later adult male sexual function, as there is a dearth of research on this topic. It was hypothesized that men reporting a history of CSA were more likely to report sexual function issues than men with no history of CSA. Read More

Objectives: To investigate abnormal intrinsic connectivity of striatum in lifelong premature ejaculation (PE) patients compared with healthy controls (HCs) METHODS: : Forty-seven lifelong PE patients and thirty healthy controls were enrolled in the present study and underwent resting-state functional magnetic resonance imaging. The functional connectivity (FC) analysis and two-sample t-tests were applied to investigate the alterations of striatum-related connectivity in patients compared with HCs (significant threshold at p<0.05, false discovery rate corrected), and during which Fisher's r-to-z transformation was adopted and the resulting z values were used as the statistical FC values.

Background: The ejaculation latency (ELT) criterion for men with premature ejaculation (PE), including its 2 major subtypes of lifelong and acquired, relies heavily on expert opinion, yet such information represents only one source of data for this determination; furthermore, information regarding ELTs for PE within specific subgroups of men (eg, gay, bisexual) has been lacking.

Aim: To obtain data regarding men's lived experiences and expectations regarding typical ejaculation, ideal ejaculation, and PE and (for men) self-reported ejaculatory latencies during partnered sex across a variety a groups, including men vs women (ie, sexual partners of men), men with and without PE, and straight vs gay/bisexual men.

Methods: We recruited 1,065 men and sexual partners of men, asking them to estimate typical ejaculation, ideal ejaculation, and PE and (for men) self-latencies through an online survey posted on social media. Read More

Premature ejaculation has a complex etiology, and its pathophysiology is still unclear, with penile hypersensitivity being the most accepted hypothesis. The aim was to investigate the efficacy and safety of a computed tomography-guided pudendal nerve block at the level of the sacrospinous ligament and the Alcock's canal in patients with premature ejaculation refractory to conventional pharmacological treatment. This is a prospective pilot study involving five patients suffering from premature ejaculation refractory to standard treatment and clinical features of pudendal nerve entrapment. Read More

Objective: To explore the topological properties of the betweenness centrality of the nodes and edges in the brain white matter network of premature ejaculation (PE) patients and analyze the correlation of the importance of the key brain regions and interregional white matter structural connectivity with the ejaculatory function of the patients.Method: We collected the demographic and clinical data, along with the T1 and MR diffusion tensor imaging (MR-DTI) data, on 18 PE patients and 22 normal controls matched in age, sex and education. After preprocessing of the data obtained, we divided the whole brain into 90 symmetrical cortical and subcortical regions (defined as nodes of the brain network) by automated anatomical labeling, examined the structural connectivity between different brain regions by probabilistic white matter fiber tracking (defined as edges of the brain network), and calculated the betweenness centrality of the nodes and edges using the brain connection toolbox.

Electrophysiological examination of penile nerves involves detection of somatic and autonomic nerves, including dorsal nerve somatosensory evoked potential, cavernous muscle reflex, skin sympathetic response, cavernous electromyography, and others, which plays an important role in the diagnosis of male sexual dysfunction, such as ED and premature ejaculation, as well as in the selection of treatment methods and evaluation of therapeutic effects. Due to the complex mechanisms of the brain, spinal cord and peripheral nerve pathways relating to erectile and ejaculatory centers in men and many unknown areas in penile electrophysiological techniques, penile electrophysiological examination has not been widely accepted by doctors and patients. Further studies are needed to provide more scientific and convincing evidence in this field. Read More

Premature ejaculation is a common male sexual dysfunction disorder, and there are many controversies over its definition. With deeper insights into the etiology and pathogenesis of premature ejaculation, more and more auxiliary examinations are used in its diagnosis, prognostic evaluation and treatment, such as transrectal ultrasonography of seminal vesicles, determination of serum 5-hydroxytryptamine (5-HT) concentration, serum hormone levels, penile sensitivity detection, brain function tests, and genetic sequencing. This review outlines the latest advances in the auxiliary examination of premature ejaculation and provides clinicians with some diagnostic indexes or methods of premature ejaculation for reference.
