Experimental Points

Reproductive Acupuncture Points Used in Experimental Studies

Over the past decade, small groups of researchers have attempted to clarify the potential effects of acupuncture on female reproductive organs under strict laboratory-controlled conditions. Many experimental studies on ovarian and uterine blood flow are conducted using anaesthetized rats. The advantage of studying on anaesthetized animals is that it eliminates potential placebo effects and other unspecific influences that are often prevalent in human clinical studies.

Experimental studies on rats demonstrated influences of acupuncture or acupuncture-like somatosensory stimulation on ovarian and uterine blood flow.1-7  The responses were elicited via spinal and/or supraspinal reflexes. Studies on humans further supported the efficacy of acupuncture on uterine blood flow.8 9

Based on both the experimental studies and traditional Chinese meridian theory, it can be considered that selecting traditional acupuncture points located within the areas of reproductive organ dermatomes (T10-L2 and S2-S4) would produce a profound impact on reproductive organs via spinal segmental reflexes.

There are many acupuncture points traditionally used for fertility that are located outside of the dermatomes. Those points are considered to influence reproductive organs via supraspinal reflexes and other known and unknown mechanisms.
