[Dynamics of milk ejection reflex during continuous rhythmic stimulation of areola-nipple complex of the mammary gland].
In continuous 10-minute simultaneous action of the vacuum and compression stimuli at a 1 cycle/second frequency, the rate of the milk ejection from the breast was periodically changing in lactating women. The milk flow first peaks latency was 0.5-3.0 minutes, the number of peaks being 2-7 per minute with the inter-peak interval 2-4 minutes during a 10-minute milk ejection. The women revealed an individual pattern of the milk flow peaks. The findings suggest that a central gate mechanism intervenes to set the periodicity of the milk ejection.
