Which hormone, secreted from the hypothalamus, inhibits the production of prolactin?

Dopamine is indeed the hormone secreted from the hypothalamus that plays a crucial role in inhibiting the production of prolactin. Prolactin is a hormone responsible for stimulating milk production in breastfeeding individuals and has various other functions, including influencing reproductive health. The hypothalamus regulates prolactin secretion from the anterior pituitary gland through the release of dopamine into the bloodstream. When dopamine is present, it binds to specific dopamine receptors in the pituitary, effectively inhibiting the release of prolactin. This negative feedback mechanism is important for maintaining hormone balance within the body and ensuring that prolactin levels are kept in check when lactation is not occurring or is not needed.
