Abstract

The biochemical mechanisms of the initiation of human labour are not yet understood. Much of the work in this field has been done in animals, but there are fundamental differences in placentation, the anatomy of pregnancy and the ways in which parturition is controlled. Thus it is not always possible to draw parallel conclusions between these animals and man.
