There are both endocrine and exocrine regulatory mechanisms.
Stimulation of the breast (by suckling, pumping, manual expression, etc.)
produces prolactin, which stimulates the breast to produce milk. If milk
remains in the breast, milk production is reduced; the more milk remaining,
the more reduction. The first is most important in the early postpartum
period, the second after production is established.
