What hormones are released when breastfeeding?

The Hormonal Symphony of Breastfeeding
Breastfeeding is not just a nurturing act; it is a complex physiological process governed by a delicate interplay of hormones. These hormones play crucial roles in milk production and ejection, ensuring that mothers can provide the necessary nourishment for their infants. The primary hormones involved in this process are prolactin and oxytocin, along with estrogen and progesterone, which contribute indirectly.
Prolactin: The Milk Producer
Prolactin is often referred to as the “milk hormone.” It is primarily responsible for stimulating the production of milk in the mammary glands. After childbirth, levels of estrogen and progesterone, which were high during pregnancy, drop significantly. This decline allows prolactin levels to rise, preparing the body for breastfeeding . When a baby suckles at the breast, sensory signals are sent from the nipple to the mother’s brain, prompting the release of prolactin. This hormone not only promotes milk synthesis but also helps in maintaining milk supply as long as breastfeeding continues.
Oxytocin: The Milk Ejector
While prolactin is essential for milk production, oxytocin plays a pivotal role in the ejection of milk. Often dubbed the “love hormone,” oxytocin is released in response to the baby’s suckling. It causes the muscles around the milk ducts to contract, facilitating the letdown reflex, which allows milk to flow to the nipple. This hormone also contributes to the emotional bonding between mother and child, promoting feelings of relaxation and calm during breastfeeding.
The Role of Estrogen and Progesterone
Although estrogen and progesterone are not directly responsible for milk production, they are crucial during pregnancy for preparing the breasts for lactation. These hormones help develop the milk-producing glands and ducts. After childbirth, their levels drop sharply, which is necessary for the effective functioning of prolactin and oxytocin. This hormonal shift is vital for initiating breastfeeding and ensuring that the mother can produce milk effectively.
The Emotional and Physiological Impact
The release of oxytocin during breastfeeding not only aids in milk ejection but also fosters a sense of well-being in mothers. It can induce feelings of relaxation and even drowsiness, which are beneficial for both mother and baby during this intimate bonding time. This emotional connection is further enhanced by the physical act of breastfeeding, creating a nurturing environment that supports the infant’s development.
Conclusion
In summary, breastfeeding is orchestrated by a complex hormonal interplay that includes prolactin for milk production and oxytocin for milk ejection, alongside the preparatory roles of estrogen and progesterone. This intricate system not only ensures that infants receive the nourishment they need but also strengthens the emotional bond between mother and child, highlighting the profound nature of this biological process.

What happens to hormones when done breastfeeding?

“As women wean, the oxytocin stores start to go back to non-pregnant levels,” O’Neill says. “Oxytocin is known as the love hormone, so as it decreases you may feel sad, irritable or grumpy. Many women attribute this to fatigue, but the feeling is real and regulated by our hormones.”

What hormones are released during breastfeeding?
