milk ejection reflex


Also found in: Dictionary.

milk ejection reflex

a normal reflex in a lactating woman elicited by tactile stimulation of the nipple, resulting in release of milk from the glands of the breast. This reflex requires intact nerve connections from nipple to hypothalamus and release of the hormone oxytocin from the posterior pituitary into the bloodstream. Also called let-down reflex.

milk ejection reflex

A reflex stimulated by suckling and mediated by oxytocin in which milk is moved from the breast alveoli into the milk ducts.

Oxytocin, also released in response to the suckling stimulus, promotes the milk ejection reflex and emptying of the breast; however, it is the actual removal of milk from the breasts, in a constant favourable hormonal environment, which controls milk production.
Despite Lawton and Kesaniemi stating that these levels would not affect the infant, it should be noted that these levels are higher than that in many of the studies found to inhibit the milk ejection reflex (26,30,38-40) (evidence level Mennella (40)--NHMRC III-1), higher than the level at which motor development in the infant was affected, (43) and higher than that recommended by the Institute of Medicine (evidence level--NHMRC V, expert authority).
In animal and human studies alcohol has been shown to disrupt the hormonal control of lactation by decreasing the milk ejection reflex through the inhibition of oxytocin.
