The Secrets Behind Prolactin and Oxytocin

Prolactin and oxytocin are the two primary hormones that women need in order to produce breast milk. They are naturally produced in the brain, and when they are released, they signal the milk glands in the breasts to produce and release milk for the baby. So, if your body already produces these hormones naturally, why bother stimulating their production?


Prolactin, as the name suggests, promotes lactation. It is produced in the pituitary gland during the last weeks of pregnancy and its levels increase after childbirth. However, mothers who give birth prematurely often don't have enough milk for their newborns because their prolactin levels haven't had a chance to rise. The best way to increase prolactin production is by pumping frequently and at regular intervals. Nipple stimulation is key here, as it helps signal the brain to get the milk-making process going. Exercise can also boost prolactin levels.


Oxytocin, also known as the "love hormone," is produced in the hypothalamus and released into the bloodstream. It plays a role in childbirth, orgasms, and milk release, and it is also involved in bonding between mothers and their babies. Oxytocin is stimulated by the baby's suckling motion, so the more a baby nurses, the more oxytocin is released.

Where Annabella Comes In

The Secret Behind the Baby's Tongue Traditionally, breast pumps have relied on increasing the suction to extract milk from the breasts. However, the process of breastfeeding involves more than just suction; it also involves the motion of the baby's mouth and tongue. These motions stimulate the brain to produce more prolactin and oxytocin, which can help increase milk production.

That's where Annabella comes in. Instead of simply increasing the suction, our pump works with your body's natural processes to stimulate the production of prolactin and oxytocin. It mimics the motion of the baby's tongue, signaling the brain to boost its prolactin and oxytocin levels. This can help you pump more milk more easily, without straining your body.

Prolactin and oxytocin are essential hormones for breast milk production, and they are naturally stimulated by the baby's suckling motion and other forms of physical contact. Traditional breast pumps rely on suction, but Annabella takes a different approach by mimicking the motion of the baby's tongue to stimulate the production of these hormones. This can help you pump more milk more easily and effectively, without straining your body. It's about time for a breast pump like Annabella, one that works with nature rather than against it.
