ヨガの早漏に対する効果：システミックレビューとメタアナリシス

Premature ejaculation (PME) is one of the most common male sexual disorders, affecting 20-30% of men globally. While various treatments exist, including pharmacological interventions, there is growing interest in yoga as a non-pharmacological approach. This systematic review and meta-analyse evaluated the effectiveness of yoga interventions for premature ejaculation. A systematic search was conducted across PubMed/Medline, EMBASE, Scopus, Google Scholar, and Web of Science databases from 1990 to January 2025. Studies comparing yoga interventions for PME were included, and data was analysed using random effects model. Five studies met inclusion criteria, with three providing data suitable for meta-analysis. The meta-analysis showed a significant positive effect of yoga interventions (SMD = 1.74, 95% CI: 1.27-2.22), though with high heterogeneity (I² = 90.7%). One study comparing yoga with fluoxetine showed greater IELT improvement in the yoga group (79.6 vs 34.2 seconds). Studies comparing yoga with non-pharmacological interventions also demonstrated favourable outcomes for yoga. Importantly, no significant adverse effects were reported in yoga groups, while pharmacological interventions showed side effects in up to 46.4% of participants. Yoga appears to be a promising intervention for PME, potentially working through stress reduction, autonomic nervous system modulation, and pelvic floor strengthening. However, the evidence is limited by small sample sizes and methodological heterogeneity. Larger, well-designed randomized controlled trials are needed to establish yoga's efficacy as a standard treatment option for PME.
