Abstract: A non-invasive and accurate vagina evaluation device and uterine evaluation devices are provided that measure the receptivity (uterine implantation capacity) of the mother's body to a fertilized egg implanting itself into the uterus. A first vagina evaluation device includes: a main body stretchable and expandable after insertion into a vagina, followed by air injection thereinto; four electrodes brought into contact with the vagina wall as the main body expands and stretches; and a fixation device configured to fix the interval of arrangement of the electrodes. Second and third uterine evaluation device include: a flexible and rod-shaped main body for insertion into a uterine cavity; and four or two impedance electrodes arranged with a predetermined interval therebetween in an insertion direction of the main body and brought into contact with an endometrium of the uterine cavity to measure a uterine endometrial impedance generated between the endometrium and each of the electrodes.
