In order to determine the mobile activity of the uterus upon the insertion of a foreign body, 30 mature rabbits were fitted with electrodes in the area of the cervix and then inserted with a polymer, which was made from a small piece of a standard Lippes Loop. 15 of the animals were fitted with electrodes but not administered the polymer in order to serve as a control. The amount of biopotential registration was measured 4-5 days, 7-9 days, and 13-15 days after the insertion. The animals with the polymer were shown to exhibit a much higher and more expressed level of contractile activity than the control animals. This contractile activity is thought to create unfavorable conditions for fertilizations and the implantation of the sperm.
