Prevalence and Factors Associated with Premature Ejaculation in Japan: First Nationwide Cross-Sectional Survey by the Japanese Society for Sexual Medicine.

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
purposePremature ejaculation (PE) is a most common sexual complaint among men worldwide, but its prevalence and associated factors in Japan remain underexplored. This study aimed to determine the prevalence of self-reported PE, lifelong PE (LPE), and acquired PE (APE) among Japanese men, as well as to identify associated factors, distress levels, and healthcare-seeking behaviors through a nationwide cross-sectional survey. MATERIALS AND
methodsThis internet-based nationwide cross-sectional survey was conducted among Japanese men from 20 to 79 years old by the Clinical Research Promotion Committee of the Japanese Society for Sexual Medicine (JSSM). Data were collected using validated questionnaires, including the International Society for Sexual Medicine (ISSM) criteria for LPE and APE.
resultsOf 37,485 invited participants, 6,228 provided valid responses (response rate: 16.61%), with 5,331 sexually active men included in the analysis. The prevalence of self-reported PE distress was 23.39%. ISSM-defined LPE and APE were observed in 0.54% and 3.47% of respondents, respectively. Univariate analysis identified erectile dysfunction (ED), psychotropic drug use, neurological diseases, trauma, aortic aneurysm surgery, and partnership dissatisfaction as significant associated factors for both LPE and APE. Multivariate analysis confirmed ED as the common associated factor. Despite 51.00% of respondents expressing a desire for treatment, only 4.81% had sought medical help.
conclusionsThis study provides the first epidemiological insights into PE in Japan, revealing a notable prevalence and identifying ED as a key associated factor. Despite significant distress, most affected individuals do not seek medical help, highlighting the necessity for greater public awareness and better access to treatment options. Future research should focus on longitudinal assessments to explore causal relationships and evaluate potential interventions.
