What causes onset of labor (Part 3): Role of oestrogen

Various mechanisms are involved wherein the oestrogen helps in the parturition process. It helps in releasing oxytocin from the maternal pituitary gland and also increases the number of oxytocin receptors on the myometrium. By accelerating the lysosomal disintegration in decidual and amnion cells, it increases the secretion of prostaglandins. Furthermore, it enhances the myometrial contraction protein and excites the myometrial cell membranes.
