Which of the following hormones is responsible for both the milk ejection reflex and the foetal ejection reflex?
(1) Relaxin
(2) Estrogen
(3) Prolactin
(4) Oxytocin

The correct answer is (4) Oxytocin.

This is because – Foetal ejection reflex triggers release of oxytocin from the maternal anterior pituitary gland. Oxytocin acts on the uterine muscle and causes stronger uterine contractions. Milk ejection reflex is caused by combined neurogenic and hormonal reflexes that involve release of oxytocin from posterior pituitary gland.
