Which hormone released by the pituitary gland is associated with labor contractions and social bonding?

• A. Dopamine
• B. Oxytocin
• C. Adrenaline
• D. Testosterone

Answer: (B)

Oxytocin is the hormone released by the posterior pituitary that drives both labor and social bonding. In childbirth, its release stimulates rhythmic contractions of the uterus, helping push the baby out. It also supports social bonding, promoting maternal behaviors and affiliative connections, such as trust and social bonding with others. Oxytocin is made in the hypothalamus and transported to the pituitary for release, and it also aids in milk ejection after birth. The other options don’t fit these roles: dopamine is about reward signaling, adrenaline is a stress hormone from the adrenal glands, and testosterone is an androgen linked to male characteristics rather than labor contractions or bonding.
