In females, prolactin tell the breasts to start producing milk (but it is another hormone, oxytocin, that actually causes the milk to be excreted).  In both sexes, prolactin also inhibits LH and FSH release, which inhibit estrogen/progesterone secretion and ovulation in females, and testosterone secretion and sperm production in males.  Overproduction of prolactin (like from a tumor or a dopamine antagonist) can cause infertility and decreased sex drive in both sexes.
