The initiation of labour in humans involves a neuroendocrine mechanism in which signals originating from the fully developed foetus and placenta lead to:
| 1. | Estrogen withdrawal resulting in relaxation of uterine muscles |
| 2. | Progesterone secretion that maintains uterine quiescence |
| 3. | Oxytocin release causing stronger uterine contractions through positive feedback |
| 4. | Inhibition of uterine contractions until parturition is complete |
