is prolactin inhibits the release of milk from breast but stimulate milk production
Yes, that is correct. Prolactin is a hormone that stimulates milk production in the breasts. It is secreted by the pituitary gland in response to the suckling or stimulation of the nipples. Prolactin promotes the growth and development of mammary glands, as well as the synthesis and secretion of milk components. However, it is the hormone oxytocin that is responsible for the ejection or release of milk from the breast, usually triggered by the suckling of a baby.
Yes, that's correct. Prolactin is a hormone that plays a key role in milk production in mammals. It stimulates the growth and development of milk-producing glands in the breast. During pregnancy, prolactin levels increase, preparing the breasts for milk production. However, the release of milk from the breast is inhibited by another hormone called oxytocin. When a baby suckles at the breast, oxytocin is released, causing the muscles around the milk glands to contract and push the milk out. So, while prolactin stimulates milk production, oxytocin is responsible for the actual release of milk from the breast.
Yes, you are correct. Prolactin is a hormone that is responsible for milk production in the mammary glands of the breasts. It is produced and released by the pituitary gland in the brain.
To explain how prolactin inhibits the release of milk from the breast but stimulates milk production, we need to understand the process of lactation.
During pregnancy, high levels of estrogen and progesterone prepare the mammary glands for milk production. After childbirth, when the placenta is expelled, the levels of estrogen and progesterone drop significantly and allow prolactin to take over.
Prolactin stimulates the production of milk by promoting the growth and development of milk-producing cells in the mammary glands. It triggers milk synthesis and pushes the produced milk towards the breast ducts.
However, during the early stages of breastfeeding, milk ejection (letdown) is inhibited by the hormone called oxytocin. This is because the stimulation of the breasts during breastfeeding triggers the release of oxytocin, which causes the muscles around the milk-producing cells to contract, squeezing the milk out of the mammary glands and into the ducts for the baby to feed.
So, while prolactin stimulates milk production, it is oxytocin that is responsible for milk ejection or the release of milk from the breast. The release of prolactin and oxytocin are both regulated by the suckling action of the baby.
