Quizplus · Accepted Answer

Milk ejection from the breasts (also known as let-down) is primarily stimulated by the hormone oxytocin, which is released in response to suckling or nipple stimulation. Prolactin also plays a role in milk production, but it is not directly involved in milk ejection. Colostrum is the initial breast milk produced during pregnancy and in the first few days after birth. Estrogen is important for breast development during puberty, but it is not directly involved in milk production or ejection.
