Question

Quizplus · Accepted Answer

Oxytocin is the hormone responsible for stimulating the muscular contractions during labor and delivery. It is released by the pituitary gland in response to the stretching of the cervix and uterus during childbirth. It helps the uterus contract during labor and also stimulates the letdown of breast milk during breastfeeding. Estrogen and progesterone play a role in preparing the uterus for pregnancy, but do not have a direct effect on the contractions. Luteinizing hormone (LH) is involved in ovulation and the menstrual cycle, but is not directly involved in childbirth.
