Vagina evaluation device and uterus evaluation device

A uterine evaluation device for biological evaluation of a subject's uterus, the device comprising:

• a rod-shaped main body capable of being inserted into a uterine cavity;
• three electrodes arranged with a predetermined interval therebetween in an insertion direction of the main body, the electrodes being brought into contact with an endometrium of the uterine cavity, wherein the electrodes include a uterine redox potential difference electrode arranged entirely at the distal end of a tip of the main body in the insertion direction of the main body to measure a redox potential difference between the uterine cavity and a body surface, and two impedance electrodes arranged with a predetermined interval of 6.0 to 6.5 mm therebetween in the rear of the redox potential difference electrode in the insertion direction to measure a uterine endometrial impedance generated between the endometrium of the uterine cavity and each of the impedance electrodes;
• a body surface electrode;
• and
• a measurement device configured to measure the redox potential difference between the uterine redox potential electrode and the body surface electrode,
• wherein the uterine redox potential electrode is electrically coupled to the measurement device, and wherein the body surface electrode is also electrically coupled to the measurement device.
