Use
Oxytocin is a natural hormone that manages key aspects of the female and male reproductive systems, including labor and delivery and lactation, as well as aspects of human behavior. Your hypothalamus makes oxytocin, but your posterior pituitary gland stores and releases it into your bloodstream.Large doses cause tonic contractions in the uterine muscles, so it is used clinically to burst blood vessels between muscle fibers, prevent postpartum hemorrhage, and ensuring postpartum recovery. It can also promote lactation by causing the breast ducts to contract and expel milk from the breasts, but it cannot increase the lactation amount.
