We bought a mare who has failed to settle since her last foal in 1999. She was bred 3 times since then. We tried to get a culture (she is now in heat 2nd day) and the vet has found that her cervix is sealed shut. He says he can get about a fingers depth in, but no farther. He is not a repro specialist and is making some calls for me about how to proceed. Can this mare's cervix be reopened enough to get her bred? And what will happen if it seals over again and she tries to foal?
Her uterus is in good shape with no fluid and no cysts...so we are hoping if we can get the cervix open she should settle.

The first consideration is whether this mare is in estrus ("heat") or not! In the event that she is not, gaining uterine access through the cervix will be more difficult. Note that the presence of follicles on the ovary does not necessarily indicate that the mare is in estrus, as mares can and do have follicles on the ovaries during diestrus.

The cervix can be convoluted and have blind ends on some mares, so it is also possible that your vet is not able to get his finger through as he has "taken a wrong turn" in his trans-cervical trip! Note too, that the cervix is only about the length of a finger (±3 inches), so your vet must have been very close to gaining access to the uterus.

Some mares do not have a terribly relaxed cervix even during estrus, and these mares can present problems at breeding time as they will tend to retain uterine fluid pre- and post-breeding. Use of a cervical relaxant drug such as ECP or topically applied prostaglandin E (not systemic prostaglandin F2a ) may assist with those mares.

Finally, yes, there can be cervical adhesions, but I would make sure you rule everthing else out before jumping to that conclusion, as although they do happen, they are not that common. In the event that there is an adhesion, yes, it can be opened. But worry about first things first, like whether she is truly in estrus! :-)

Hello, Thanks...we are pretty sure she is heat, she had a 25mm follicle last week(on US exam) and she has no fluid that we can see. She was teased with the stud daily, since that day, and finally started to show to the stud on the 27th. So we are going to give it until Monday and recheck her cervix again, hoping the farther along her heat the softer it will be. I will suggest to my vet about the ECP or topical prost. And see what he is willing to try. Fingers crossed that this is just a case of a really tight cervix! Thank you for the suggestions.

Jos, I passed on your advise to my vet. And we rechecked her last night as she is showing much hotter now. He was able to wiggle through the cervix! YEAH! We got a culture and did an ultrasound and found a 35follicle (still no fluid). We plan to breed her in the morning after we receive the culture results. Thank you for your advice, I admire my vet...but I am thinking with all the breeding I do...I might want to find a repro specialist for these kinds of things. Thanks!

No uterine fluid is good... you don't want uterine fluid! It can be an undesired sequela of the tight cervix in some mares.

It sounds as though your mare was simply not far enough along in her estrus for the cervix to be relaxed - they do tend to be more relaxed closer to ovulation, as a result of the estrogen that is secreted by the follicle.

WRT "culture results"... was there a cytology smear prepared and reviewed in conjunction with the culture? If not, the culture results are worthless. For more information on that topic, you might want to review the article on the importance of cytology on the web site (follow that link!) - Sorry to give you more headaches! :-)

Ok...I will call the clinic in the morning and ask if they did a Cytology smear. If they did'nt is it too late? Can they use the sample they obtained for the culture after a couple days?

Well, no Cytology was prepared. But her culture came back clean. We went ahead and bred her and if she comes back open we will do another culture and a Cyt. Smear. Thanks for the heads up, this is keeping my vet on his toes...LOL
