Lifelong premature ejaculation was diagnosed based on both patient self\u2010report of premature ejaculation status and scores on the Premature Ejaculation Diagnostic Tool, with a control group consisting of non\u2010premature ejaculation individuals included for comparison. Utilizing receiver operating characteristic curve analysis, the optimal self\u2010estimated cutoff value for intravaginal ejaculation latency time in diagnosing lifelong premature ejaculation was determined.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 307 heterosexual participants (mean age\u00a0=\u00a030.7\u00a0\u00b1\u00a06.4) were included, comprising 187 lifelong premature ejaculation patients (mean age\u00a0=\u00a028.0\u00a0\u00b1\u00a04.6) and 120 non\u2010premature ejaculation individuals (mean age\u00a0=\u00a035.0\u00a0\u00b1\u00a06.5). 2.7% of lifelong premature ejaculation patients experienced anteportal ejaculation. 59.9%, 92%, and 97.9% of lifelong premature ejaculation patients displayed intravaginal ejaculation latency times within 1, 2, and 3 min, respectively. The receiver\u2010operating characteristic curve's area under the curve was 0.996 with a 95% confidence interval of 0.991\u20131.000 (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.0001). The perceived intravaginal ejaculation latency time cut\u2010off at 3.5 (sensitivity\u00a0=\u00a097.9%, specificity\u00a0=\u00a099.2%) showed the highest Youden index compared with other
