== Introduction ==
In most domestic species, maintenance of pregnancy requires prolonging the life of the corpus luteum/corpora lutea. As a result, progesterone concentrations remain elevated. This results in negative feedback on the hypothalamus and anterior pituitary gland, thus inhibiting follicular development and ovulation. In polyoestrous species, it prevents the return to oestrus. In many species, the placenta will take over or supplement the corpus luteum as the source of progesterone.
