- Parturition is initiated by the foetal ejection reflex, a neural mechanism of mild contractions of the uterus, initiated by the fully developed foetus and placenta.
- It triggers the release of oxytocin from maternal pituitary, which causes stronger contractions of uterine muscles and stimulates more secretion of oxytocin.
- The stimulatory reflex between uterine contractions and secretion of oxytocin continues and results in parturition, i.e. the delivery of the baby; hence it is called a neuro-endocrine mechanism.
