Abstract

Abstract The action of copper and zinc upon myometrial activity of the rabbit uterus was studied indirectly by observing the behaviour of “inert” (polyethylene segments) and “active” (copper and zinc wires) IUFBs upon the uterine activity of estrous and pregnant does. It was observed that “inert” foreign bodies were rapidly expelled from the rabbit uterus whereas the “active” ones were retained and transported in the direction of the utero-tubal junction. The differences observed were statistically significant and support the idea that metal IUFBs affect myometrial function of the rabbit uterus. The mechanism possibly responsible for this change is discussed.
