What is lactogenesis?

Lactogenesis is the process by which mammary glands produce milk, typically occurring in two stages. The first stage, known as lactogenesis I, begins during pregnancy when hormonal changes prepare the breast tissue for milk production. The second stage, lactogenesis II, occurs after childbirth, triggered by the drop in progesterone and the onset of breastfeeding, leading to the secretion of mature milk. This process is crucial for providing essential nutrients to newborns.
