Oxytocin and prostaglandins work together to stimulate uterine contractions during true labor.
Oxytocin stimulates uterine contractions and the release of prostaglandins. As labor nears, a positive feedback loop occurs between the uterus, hypothalamus, and the posterior pituitary to ensure an adequate supply of oxytocin, leading to stronger, more painful uterine contractions. Prostaglandins and oxytocin play crucial roles in the initiation and maintenance of labor.
