The three "front" hormones are Progesterone (which keeps the mare OUT of estrus); estrogen (which makes the mare display estrus); and prostaglandin (which destroys the CL - which is the origin of the Progesterone - thereby letting the mare enter estrus). The controlling hormones behind these are primarily FSH (Follicle Stimulating Horomone) and LH (Luteinizing Hormone), both of which are influenced themselves by GnRH (Gonaodtropin Releasing Hormone), which can be controlled in turn by Melatonin, presence of high levels of which can suppress the estrus activity - which results in the winter anestrus effect.
I will address the lack of an available article on this subject in the near future - check back in soon!!
Note: I have now provided an endocrinology article which can be found by clicking here.

My 27 year old AQHA mare has an enlarged udder. She has not been around stallions and shows no signs of being pregnant. I'm worried about breast cancer. Can you give me any information about the rate of occurance for mares and possible treatments and their success? Thank you.
