Lactation is a hallmark feature of female mammals. Lactation is under endocrine control. The two main hormones involved are prolactin and oxytocin. Lactogenesis, or the process of changes to the mammary glands to begin producing milk, begins during the late stages of pregnancy.

What is milk ejection reflex?

Can a 60 year old woman produce milk?

All she needs are functioning breasts and pituitary glands. After menopause, this is done through the process of relactation.
