Both oxytocin from the posterior pituitary and prostaglandin from the decidua stimulate uterine contractions. Oxytocin is released during labor to stimulate contractions and prostaglandins are produced in the decidua (the lining of the uterus) to help soften and thin the cervix and promote contractions. Progesterone, on the other hand, helps to maintain the pregnancy by preventing contractions.
