Abstract

Luteolytic mechanisms have evolved in mammals to improve reproductive efficiency. The hormonal interactions that control the onset and progress of luteolysis are complex. They involve endocrine and paracrine signals that link the corpus luteum, uterus and posterior pituitary gland. Current conceptsconcerning these interactions will be examined in the five major domestic ungulate species commonly raised in Europe and North America (cattle, sheep, goats, pigs and horses). Some of these interactions are similar across species. All five depend on prostaglandin F-2 alpha secreted from the uterus,to induce luteolysis. Three hormones, progesterone, estradiol and oxytocininteract to regulate uterine secretion of PGF(2 alpha). Oxytocin is an acute stimulus for uterine PGF(2 alpha) secretion. Progesterone and estradiol interact to regulate uterine secretary responsiveness to oxytocin. Precisely how these hormones interact varies across species.
