This study is another in a series of studies demonstrating that acupuncture has point and frequency specific effects. Meaning that when an acupuncture needle is inserted at a particular point it may not improve blood flow until the proper frequency is administered. Likewise if the proper frequency is used but at the wrong point, you still won’t get increases in blood flow.
So when you use the correct point stimulated at the correct frequency you get results. In this study the results were significant increases in testicular blood flow (St 29 @ 10hz).
