Sympathetic hyperactivity in situational delayed ejaculation (intravaginal anejaculation phenotype): a neurophysiological case-control study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Situational delayed ejaculation (SD-DE, intravaginal anejaculation phenotype) is a clinically significant disorder marked by preserved masturbatory function but persistent coital anejaculation. This condition substantially impairs quality of life and causes significant distress. The underlying neurophysiology, particularly autonomic mechanisms, remains unclear. This study aimed to investigate sympathetic function in SD-DE using penile sympathetic skin response (PSSR) and assess its clinical correlates. Methods: Sixty-seven SD-DE patients and 65 normal controls (NCs) were enrolled. PSSR latency and amplitude, penile sensory threshold (PST), and clinical characteristics (including psychological evaluations via the Self-Rating Anxiety Scale, SAS) were systematically analyzed to evaluate sympathetic nervous system function. Results: SD-DE patients exhibited significantly shorter PSSR latency compared to NCs (P<0.001), indicating sympathetic hyperactivity. A significant negative correlation was observed between PSSR latency and anxiety scores (P<0.001), suggesting stress-mediated sympathetic overactivation. SD-DE patients also demonstrated higher PST (P=0.03), increased masturbation frequency (>2 times/week: 38.81% Conclusions: These findings establish sympathetic dysfunction as a core feature of SD-DE [Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) 302.74], with PSSR serving as an objective biomarker. The intravaginal anejaculation phenotype represents a distinct clinical entity within DSM-5 302.74, informing targeted therapeutic strategies. In the future, it is necessary to further verify its pathological circuit mechanism by combining multimodal neuroimaging techniques.
