In the simplest format, the main hormones that maintain or end pregnancy are
Progesterone levels control pregnancy duration and are initially produced by the corpus luteum and by subsequent ovulations that produce secondary corpus lutea. Finally produced by the fetoplacental unit...progesterone decreases as
foal reaches maturity.
Prostiglandins can end early pregnancy (before day 35) by disrupting the corpus luteum. After day 35 with the formation of endometrial cups the mare will not return to heat even if the embryo dies in utero.
Oxytocin creates muscle relaxation and cervical dialation as well as milk production.
