Estrumate is a pgf 2 alpha analog. Without getting too technical, when your mare ovulates (releases an egg from the ovary), the ovary forms what is called a "corpus lutea" or CL for short. This structure produces progesterone, a hormone that helps maintain a pregnancy. It usually regresses if the egg does not get fertilized but sometimes it doesn't do what it is supposed to and keeps on producing progesterone. This can lead to pseudopregnancy. The Estrumate lyses, or gets rid of the CL so that it stops producing progesterone and your mare can start cycling again. Hope that helps!
