Secretion depends on electrical activity of neurons in the hypothalamus - it is released into the blood when these cells are excited. While most oxytocin is produced in an area of the brain known as the hypothalamus, some oxytocin is produced in another brain area known as the bed nucleus of the stria terminalis, or BNST. In females, it is mainly involved in stimulating the growth of prostaglandins, increasing the contractions of the muscles of the uterus, reduces the excess blood flow post-childbirth, promotes milk movement into the mammary glands.
