Acupuncture Increases Blood Flow To The Tesitcals
Eighty healthy male volunteers were randomly allocated to three groups in stage one and to a single group in stage two.
In the first stage of the study, the abdominal acupuncture points ST-29 (guilai) were stimulated using simple needle insertion, 2 Hz burst electric-acupuncture or 10 Hz electric-acupuncture, in three different groups.
In the second stage of the study, abdominal acupuncture points ST-25 (tianshu) were stimulated with the frequency found to be more effective in stage one. Stimulation was for 5 minutes in each group.
Electroacupuncture and Doppler flowmeter. Main Outcome Measure(s): Four groups were compared for volume flow and other related parameters of testical blood flow.
The 10-Hz electric-acupuncture stimulation of ST-29 (guilai) increased testical blood flow, but simple needle insertion and 2-Hz burst stimulation did not. The 10-Hz electric-acupuncture stimulation of ST-25 (tianshu) did not result in significant changes in testical blood flow.
For the first time point and frequency-specific effects of abdominal electric-acupuncture on testical blood flow are shown in humans. Further investigation is required to ascertain whether these findings may be helpful in the clinical treatment of infertile men.
