Determination of the normal position of the anus (with reference to idiopathic constipation).
The position of the normal anus was numerically defined by the ano-genital index, which is the distance from the anus to the vagina or scrotum divided by the distance between the vagina or scrotum and the coccyx. In idiopathic constipation, one must look for an anterior displacement of the anus, which might be the cause of the constipation.
