OBJECTIVE: To clarify the role of the abdominal acupuncture points and the frequency of short-term electroacupuncture (EA) stimulation on testicular blood flow (TBF) in humans.
DESIGN: A prospective, randomized study.
SETTING: University hospital, Department of Radiology, ultrasound unit.
PATIENT(S): 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 EA or 10 Hz EA, 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.
INTERVENTION(S): Electroacupuncture and Doppler flowmeter.
MAIN OUTCOME MEASURE(S): Four groups were compared for volume flow and other related parameters of TBF.
RESULT(S): The 10-Hz EA stimulation of ST-29 (guilai) increased TBF, but simple needle insertion and 2-Hz burst stimulation did not. The 10-Hz EA stimulation of ST-25 (tianshu) did not result in significant changes in TBF.
CONCLUSION(S): For the first time point- and frequency-specific effects of abdominal EA on TBF are shown in humans. Further investigation is required to ascertain whether these findings may be helpful in the clinical treatment of infertile men.
