I am using a different Vet this year. We tried all of last year to get this mare in foal, she always had the follicle on the right side.
History of mare, she is 16 years old. Had foals in 1998, 1999, 2000, and 2004.
Vet ultrasounded this year for pregnancy, and said we will not get her in foal, if she ovulates off the right side, as she has cysts that are preventing follicle, and sperm from meeting. He says we can do surgery to make her ovulate off the other side. I was wondering if there are any drugs that may work to make her have several follicles on both side, then if pregnant pinch off the ones not wanted, or would this not work?
Any suggestions?

Have you tried short cycling her. I know when I short cycle my mare she always ovulates off of the other side.....

Where are these cysts that are allegedly preventing conception?

What is the surgery that is going to cause her to ovulate only on one ovary?

I have not tried short cycling her, but have thought about it.
I think it is the Uterine horn. He said there are 2 procedures, one is surgery to remove the right side. The 2nd is to crush it, and tie it off. 1st is easier on mare, and more expensive, 2nd is a little harder, and half the price. He was not sure if that would affect her hormones to carry to term, if either were done.

Short cycling will not cause a change in the side of follicular development. Wherever the dominant follicle develops will be the side that ovulates, and that can be either side.

If the cysts are in the uterine horn, they are not going to stop passage of the sperm. Pregnancy is established in the oviduct, and the fertilized oocyte ("egg") descends in to the uterus about 6 days after that. Sometimes cysts - if large enough, and that means large enough to completely occlude the uterine horn, so probably 2-3 cm or greater - can prevent movement of the conceptus around the uterus during the 10 day period immediately after its descent into the uterus, which movement is important for achieving maternal recognition and preventing her from coming back into "heat" and losing the pregnancy. Cysts in the uterus do not impact the ability of establishment of pregnancy from an ovulation on one ovary or the other.

From the descriptions you have given, something seems not quite right with the whole picture. If all you describe is exactly what was said by your vet, you might want to get a second opinion from a veterinarian that is a specialist in equine reproduction - preferably a theriogenologist.

I called the vet tonight, it is 1 large cyst, that he says looks like it is blocking the way, as you had mentioned.
Any suggestions?

The cyst will not be blocking the passage of the sperm, but may as I noted interfere with conceptus mobility causing failure of maternal recognition.

There are several techniques for removing the cyst (there is no need to remove the uterine horn!), ranging from a basic manual crushing technique, through laser surgery to a method where a wire "loop" is placed around the base of the cyst, and it is then cauterized, thereby removing it. The correct technique will depend upon location and type of cyst, and availability of equipment and expertise. Often a GP veterinarian will not have the necessary equipment, and it will become necessary to go to a specialist or a veterinary teaching university.

There is still no technique that I am aware of - short of removing the contra-lateral ovary - that would cause a mare to ovulate solely on one side; and as noted above, there would be no advantage to it anyway even if there were.

I asked him about removing the cyst, and he said it still may grow back quickly to achieve pregnancy, is this true, and what is the average cost for what you have mentioned for removal?

While it may grow back, it's regrowth to the former size in less than 20 days would be contrary to any researched work that I am aware of.

Re costs: You should contact a veterinary clinic that has the capability of doing the work. Costs vary. As I noted previously, it may be worth while getting a second opinion anyway if you are not comfortable with the first.

Well, we short cycled her back in, bred her, and put her on regumate as soon as she was out of heat. To try and maintain pregnancy if she took.
Well it worked, after 2 years of trying and a vet that said we would never get her in foal, is, and we have a heart beat, she is over 30 days in foal!!!

Congratulations!!! That's fantastic news Chris!!! I know how hard it is mentally and financially to try and get some mares bred, I'm happy it worked for you. Now you can dream of a beautiful foal in about 10 more months.

This foal is going to be extra special, as 2 weeks ago we lost his sire, he was 28, so I am very thankful she took. We have discontinued the regumate, her levels are in normal range.
