Evaluate acupuncture treatment 30 minutes twice weekly for 2 weeks and once a week for 10 weeks for the relief of hot flashes
Seven men with vasomotor symptoms due to castration underwent the prescribed acupuncture regimen.
Hot flashes were recorded in logbooks.
Of the seven men, six completed at least 10 weeks of acupuncture therapy, and all had a substantial decrease in the number of hot flashes (average 70% after 10 weeks). At three months after the last treatment, the number of flashes was 50% lower than before therapy. Therapy was discontinued after 10 weeks because of a femoral neck fracture in one man and after three weeks due to severe back pain in another subject.
Study limitations included very small sample size, short study duration, and use of a convenience sample
