| stimulates milk production and secretion | prolactin |
| stimulates milk secretion during lactation | oxytocin |
| responsible for female secondary sex characteristics | estrogen |
| stimulates metabolic activity | thyroid hormone |
| increases blood glucose level and decreases protein synthesis | cortisol (glucocorticoids) |
