| I've been dealing with a large, painful ovary in my 6 year old mare. Had her ultrasounded last year and found a huge ovary. Put her on an injectable altrenogist to keep her from ovulating. It worked okay, although she would still ovulate through it occasionally. It must have made her feel better because she quit biting at me while being saddled. Pulled her off of it over the winter, and now that spring is here she started biting again. Had her ultrasounded this morning, and the ovary is huge again, and now it has adhesions. My vet speculated that it was a granulosa cell tumor. I asked what could be done. He said that we could remove the adhesions, but they'd probably develop again. He said really the only option is to manage her pain or remove the ovary. Since I'd like the option of breeding her in the future I don't want to remove the ovary yet. She's being put on daily regumate and hopefully that will be more consistent than the injectable.
I'm going to start researching this, but was wondering if anyone has any experience with this and how you managed and/or treated it. |

| Could you flush her and put several eggs on ice and then remove the ovary? You'd need a recipient mare, for the baby, but it might be something to think about.

Location: Arkansas | They can remove only one ovary. She won't cycle normally with a tumor on an ovary anywany. |

| I was pretty sure we could remove one and leave the other and she would still be able to reproduce.
As far as cycling normally, she does when not on any drugs. We're in the middle of her second heat cycle for the year (she's getting the effects of the lights from my broodmares). So maybe it's a positive that she's still cycling normally, might not be a tumor after all?
I'm hoping that keeping her on regumate will help. I just hate that she's sore. Today she had a larger than 50mm follicle, and he was shocked at how big her ovary was. We gave her drugs to force her to ovulate so that we can start her on the regumate in about 10 days.
I guess I just need to find a specialist and let them look at her to see what they think. |

Location: Arkansas | Granulosa cell tumors secrete testosterone so they will mess up a mare's hormones. They usually act studdy. |

| I don't know how big her ovary is but if they get to big, it'll cost you as much as a colic surgery to remove. I would guess it'll continue to grow. I'd remove the one ovary and hope for the best with the other. |

| Call silver lining herbs and see if they can suggest anything. |

| Thank you all for the information. I really appreciate it!
Edited to add - I think my vet said something about the ovary being larger than a softball, maybe even like the size of 2 softballs. So it sounds like it's already huge.

| I had a mare that would act very studly. Found out her testerone was very high. She had some serious behavior issues. But got that one ovary removed and it was day and night. She is a completely different horse. I left the other ovary in because her pedigree is nice. If you have any questions feel free to Pm me. |

| I would suggest removing the offending ovary.
I have had two mares with horrible cycling issues and enlarged ovaries. Granulosa tumors suspected but were not present. Had both mares spayed (about 18 years apart). Best thing I could have done for either mare. Ovary/s on the first mare would get to the size of a grapefruit, the second had on that was baseball sized at the time of removal.
Both would cycle through Regumate, hormone injections and herbal remedies.
Good luck! |

| Would drawing blood and checking her testosterone levels help us rule out tumors?
Other than the biting when being cinched, there are no behavior issues and no cycling issues. She doesn't act like a stud. She doesn't seem distressed when she's in a standing heat. I've heard people talk about their mares slamming into panels and such because of the pain. She doesn't do anything abnormal.
I'm hoping that the regumate will shut her down and help with the size and the pain of the ovary. If that gets things under control and she feels well, then we'll just keep managing it that way. But if that doesn't work, I guess I'll be looking at having the ovary removed.
Thanks again for all of the input. These reproductive issues are so frustrating. My 5 year old mare was having issues last year, and I thought we had it under control. But she's started swishing her tail and being grouchy so I decided to have her checked again. She had a luteinized follicle, so now we're working on getting that cleared up. |
