Which hormone stimulates milk production in the breast (mammary glands)?
A
Oxytocin
B
Follicle-stimulating hormone (FSH)
C
Prolactin (PRL)
D
Thyroid-stimulating hormone (TSH)
Verified step by step guidance1
Understand the role of hormones in lactation by reviewing the functions of each hormone listed: Oxytocin, Follicle-stimulating hormone (FSH), Prolactin (PRL), and Thyroid-stimulating hormone (TSH).
Recall that Prolactin (PRL) is the hormone primarily responsible for stimulating milk production in the mammary glands after childbirth.
Recognize that Oxytocin, while important in breastfeeding, mainly causes milk ejection (let-down reflex) rather than milk production.
Note that Follicle-stimulating hormone (FSH) is involved in reproductive processes such as ovarian follicle development, not milk production.
Understand that Thyroid-stimulating hormone (TSH) regulates thyroid gland activity and metabolism, and does not directly influence milk production.
