What is Prolactin: and explain in detail?
Prolactin, though structurally related to growth hormone does not share its somatotropic activity. Dopamine binds to the lactotropes and inhibits the synthesis and release of prolactin. Hyperprolactinemia suppresses the hypothalamic-pituitary-gonadal axis, causes infertility in women and suppresses the normal menstrual cycle in lactating women.
