The primary premature ejaculation (PPE) is a common male sexual disorder. We proposed a novel behavioral therapy for PPE through regular penis-root masturbation (PRM). Nine heterosexual men with PPE completed the self-controlled study. After a 3-month PRM training, the median intravaginal ejaculatory latency time (IELT) increased from 60 s to 180 s ( = 0.018), and the mean Premature Ejaculation Diagnostic Tool (PEDT) score decreased from 14.8 ± 3.7 to 12.8 ± 4.1 ( = 0.074). Five out of eight patients had the prolonged dorsal nerve somatosensory evoked potential (DNSEP). The results suggest that PRM has a short-term therapeutic effect. Randomized controlled trials are needed to validate the efficacy.
原发性早泄（PPE）是一种常见的男性性功能障碍。我们通过定期阴茎根部自慰（PRM）提出了一种治疗 PPE 的新行为疗法。9 名 PPE 的异性恋男性完成了自我对照研究。经过 3 个月的 PRM 训练后，中位阴道内射精潜伏期时间（IELT）从 60 秒增加到 180 秒（=0.018），平均早泄诊断工具（PEDT）评分从 14.8±3.7 下降到 12.8±4.1（=0.074）。8 名患者中有 5 名出现了延长的背神经体感诱发电位（DNSEP）。结果表明 PRM 具有短期疗效。需要进行随机对照试验来验证其疗效。
