Verified step by step guidance1
Understand the role of hormones in childbirth: Hormones are chemical messengers that play crucial roles in regulating various physiological processes, including childbirth.
Identify the hormone responsible for stimulating uterine contractions: During childbirth, the hormone that primarily stimulates uterine contractions is oxytocin.
Explore the function of oxytocin: Oxytocin is produced by the hypothalamus and released by the posterior pituitary gland. It is known for its role in initiating and sustaining labor by causing the muscles of the uterus to contract.
Differentiate oxytocin from other hormones listed: Prolactin is primarily involved in milk production, progesterone helps maintain pregnancy, and estrogen is involved in the development of female secondary sexual characteristics and reproductive system regulation.
Conclude with the correct hormone: Based on the functions of these hormones, oxytocin is the hormone that stimulates contractions during childbirth.
