I have what I think is an interesting situation. I have a Quarter Horse cross mare. She is coming on 11 years old now. When she was a year and a half old the person that owned her tried to breed her on her first heat, but she didn't take so he tried all summer, but it never worked so he sold her to me. When she was 3 or 4 she had a rectal exam and the vet found that her left ovary was twice the normal size and possibly cystic. She was never exposed to a stallion after that first time and she never seemed to come into heat, but now I think she just doesn't show. Last month (March 2010) I had her moved from Northwest Alabama to the Charleston Area of South Carolina. She is in with a pony gelding and a Quarter Horse gelding. About a week or so after she got to SC the pony started to try to breed her, so I teased her to a TB stud that is close to her and she teased in. She came back into heat on Tuesday so I took and put her with the TB stallion and they have been doing their thing quite often since then. I am going to leave her with him, until she comes out of heat. My question is what issues could that enlarged ovary cause?????

Well, "cystic ovaries" - or more the more common term "cystic follicles" - are actually not seen in the equine. They are a condition found in the bovine though, so I might be a little sceptical about the original "diagnosis".
I think before being concerned about what issues a large ovary could cause, I might feel inclined to confirm that there is still a large ovary present, and then determine what the cause of the large ovary was if it was still present.
You might want to have your mare checked again, and don't be surprised if there are 2 normal sized ovaries...!
That's good to hear, I'm not sure I trust the vet that made that diagnosis any ways, but I've never been able to have her looked at by another vet, but I will. It would be awesome if she gets pregnant. So here's hoping.
