PROBLEM TO BE SOLVED: To provide an apparatus for controlling a flow of sperms in a uterine tube formed by a uterine tube wall of a patient.SOLUTION: An apparatus for controlling a flow of sperms in a uterine tube comprises: an implantable constriction device for gently constricting (i.e., without substantially hampering blood circulation in the uterine tube wall) at least one part of the uterine tube BO to influence the flow of sperms in the uterine tube; and a stimulation device CSD for stimulating a wall part of the uterine tube wall. When the constriction device constricts a wall part of the uterine tube wall, a control device CD controls the stimulation device such that the stimulation device stimulates the wall part to cause constriction of the wall part constricted by the constriction device to further influence the flow in the uterine tube. The apparatus can be used to restrict or stop the flow in the uterine tube or to actively move the fluid in the uterine tube, in a state with a less risk of impairing the uterine tube. |
