Answer Details
If a nursing mother is not producing enough milk, her hormonal system is probably deficient in prolactin. Prolactin is a hormone produced by the pituitary gland that stimulates milk production in the mammary glands of the breast. When a baby suckles at the breast, nerve impulses are sent to the hypothalamus, which then signals the pituitary gland to release prolactin. Prolactin then stimulates the milk-producing cells in the breast to make and secrete milk. If there is a deficiency in prolactin, there will be a reduction in milk production, which may lead to inadequate milk supply for the baby. Testosterone is a male sex hormone and has no role in milk production. Thyroxin is a hormone produced by the thyroid gland that regulates metabolism, but has no direct role in milk production. Insulin is a hormone produced by the pancreas that regulates blood sugar levels and also has no role in milk production. Therefore, based on the description, if a nursing mother is not producing enough milk, her hormonal system is probably deficient in prolactin.
