OBJECTIVE To investigate the correlation of premature ejaculation (PE) with central lumber intervertebral disc herniation (CLIDH) and the pathogenesis of PE, and to search for a convenient, effective and non-invasive method for the treatment of PE. METHODS A total of 263 selected PE patients underwent CT, and those that were found with CLIDH were randomized into a treatment group (n=180) and a control (n=60), the former treated by lumbar traction and the latter with sertraline hydrochloride tablets, both for 24 weeks. CIPE-5 scores of all the patients were analyzed, and the ejaculation latency and sexual satisfaction were recorded before and after the treatment. RESULTS Among the 263 PE patients, CLIDH was confirmed in 240 (91%). After the treatment, CIPE-5 scores, ejaculation latency and sexual satisfaction were markedly improved in the treatment group, with significant statistic difference from pre-treatment (P < 0.01). Significant differences were also observed between the treatment and the control groups after the treatment (P < 0.05), but not in the control group between pre- and post-treatment. CONCLUSION CLIDH may be one of the important causes of most "unexplainable" PE cases. And lumbar traction, non-invasive, highly effective and easily manipulable, has provided a new access to the diagnosis and treatment of the PE patients with CLIDH.
