Identify the role of each hormone listed in the options: Oxytocin, Progesterone, Prolactin, and Estrogen.
Understand that Oxytocin is a hormone produced by the hypothalamus and released by the posterior pituitary gland, known for its role in stimulating uterine contractions during labor.
Recognize that Progesterone is primarily involved in maintaining the uterine lining for pregnancy and does not stimulate contractions.
Note that Prolactin is mainly responsible for milk production in the mammary glands and does not play a role in uterine contractions.
Understand that Estrogen is involved in the regulation of the menstrual cycle and development of female secondary sexual characteristics, but it does not directly stimulate uterine contractions during labor.
