Abstract: The present invention relates to a micro-electrical stimulation system for regulating uterine contraction and control method thereof. According to the micro-electrical stimulation system includes a body that is non-invasively inserted into the uterus; a stimulation neural electrode that inhibits uterine contraction by applying micro-electrical stimulation to the uterine inlet nerve; and a controller that sets the intensity, interval, and duration of the micro-electrical stimulation, wherein the controller sets the micro-electrical stimulation within an intensity of 100 to 5000 ?A, an interval of 100 to 200 ?sec, and a duration of 3 to 20 seconds.
