[The role of vacuum and tactile stimuli during milk ejection from the human breast].

Milk ejection in lactating women was performed by breast pump with vacuum and tactile (touch-compression) components. It was found that milk flow rate changed in a pulsatile manner at about 1-2 min interval and peaks milk flow coincided with peaks intramammary. Switch off the tactile component increased the latency of milk ejection 1.5-2 fold and decreased total flow rate 2 fold. It was concluded that touch-compressions stimuli necessary for generation milk ejection reflex and milk ejection from the women mammary gland.
