According to a recent study reported on in Renal and Urology News, acupuncture can be very useful in treating premature ejactulation in men. The study compared the drug paroxetine with acupuncture treatment and found that both were effective.
Of course, from the perspective of our patients, the acupuncture intervention would likely be preferable as it doesn't have side effects and is not used indefinitely, in the manner of paroxetine.
Another study, published in European Urology and readable here, finds:
Results from a high-quality Turkish study suggest that acupuncture is an effective non-pharmacological method for treating premature ejaculation (PE). Ninety patients with PE were randomly assigned to either acupuncture or sham acupuncture (twice per week) or standard medication (paroxetine 20mg/d), for four weeks. For verum acupuncture, needles were inserted bilaterally at four acupuncture points, Zusanli ST-36, Hegu L.I.-4, Taixi KID-3 and Taichong LIV-3, and at Yintang M-HN-3 and Zhongji REN-3, and were left for 20 minutes after deqi was obtained. Intravaginal ejaculation latency times (IELTs) were increased after treatment by 82.7, 65.7 and 33.1 seconds for paroxetine, acupuncture and sham acupuncture respectively. Premature Ejaculation Diagnostic Tool scores of paroxetine, acupuncture and sham acupuncture groups were 17.0, 16.0 and 15.5 before treatment and 10.5, 11.0 and 16.0 after treatment.
