A pituitary hormone causing contraction of the uterus in childbirth.
Hormone that stimulates the uterus in late pregnancy to initiate and sustain labor. After birth, it stimulates the uterine muscles to contract, reducing bleeding at the site where the placenta was attached.
Intravenous injections of oxytocin may be given to induce labor, improve contractions, or control hemorrhage after birth. It is also secreted during lactation. Oxytocin sprayed in the nose a few minutes before nursing improves milk production. It is secreted by the pituitary gland.
Hormone secreted by the pituitary gland; stimulates contractions of the uterus and ejection of milk.
