Objective To observe the relationship between the distribution areas of referred pain and acupoints sensitization in gynecological diseases

and to explore the regular distribution of acupoints sensitization in local areas.Methods Through the combination of clinical trials and animal experiments

the pain of the corresponding innervation dermatome region caused by primary dysmenorrhea

pelvic inflammatory disease and ovarian cysts was discussed.In the self-control clinical research

the whole body surface skin was explored by palpation method

and the surface tenderness sensation and abnormal changes in local area of 934 cases of gynecological related diseases in 7 teaching hospitals were observed and counted. In the animal experiment

9 rats were injected intrauterine injection of mustard oil as the model group

and other 6 rats were injected with normal saline as the control group. The number and parts of blue spots in the 2 groups of rats after being injected with Evans blue in the tail vein were compared. Results The gynecological diseases involved in the body surface pain and skin tissue abnormalities were mostly distributed in the lower abdomen（ 59. 04%）

the inside of the lower limbs（ 52. 97%）

the lower back and the sacral region（ 49. 18%）

overlapping or adjacent to the acupuncture points. The surface exudation points of the model rats with hysteritis were also concentrated in the lower abdomen

the lower limbs

the lower back and the sacral region.Conclusion When disease of the target organs such as uterus

ovary occur

the sensitization reaction of the surface of the corresponding segment（ T10-S1） innervation occurs regularly.
