I am just looking for some reassurance on this one. I inseminated a mare yesterday that was HOT in heat. Put about 40 mL of semen/extender in her. I withdrew the pipette and tilted the cervix up slightly for a few seconds, but the minute I pulled my hand out, she squated and peed out a great deal of the semen. Now I know I had the pipette in her cervix because it was soft and wide open. Think if she is still so hot in heat today I should put some more in her just in case? We normally breed every other day to avoid too much inflamation in the uterus - this is a 21-year-old mare that I would really like to get pregnant this go round. Any ideas suggestions?

Hi..I would stongly suggest using Oxytocin protocol to help with the clearance issue with an older mare.

I hope she took for you! Can you ultrasound and see if she ovulated first?

I am pretty sure she either ovulated last night or will ovulate today. We had her checked last Tuesday and she was at a 25 - so she is right on schedule and the timing was almost perfect. I am just worried that she peed out all the semen I put in her because she squated and pushed it out as soon as I pulled my hand out. So, if she is still showing today, I am just wondering if I should put some more in her. I usually don't worry about it because the mare will wait a few minutes before she pees and this actually helps hold the semen in the uterus, but this mare squated and spilled out the white semen/extender mix I put in her.

Bummer...but if you are sure you go some past the cervix you should be okay....hopefully Jos will chime in with his expertise.

You are right, it is a bummer. I am thinking you are right though, since I got some past the cervix I should be ok and it only takes one, but I still have that paranoid thought in the back of my head...thanks for your input though :-)

Well, the most likely cause is one of three possibilities:
  • You didn't have the pipette clear of the cervix and into the uterus (so you inseminated into the cervix and it flowed back into the vagina);
  • What you saw pushed out when your mare strained was in fact estrogenic urine (not uncommon after a mare has been bred/AI'd, and not uncommonly mistaken for semen);
  • Your mare has amazingly strange reproductive conformation! :-)
That last possibility is because the semen when passed through the cervix into the uterus - either as a result of the stallion ejaculating (which happens under normal circumstances into the cervix or directly into the uterus, not into the vagina as some believe), or the mare being AI'd - it immediately is going to drop down into the body of the uterus and towards the corpus cornual junction and uterine horns, as that portion of the reproductive anatomy should be lower down than the cervix. In other words, about the only way your mare could "squeeze" semen back out, as long as it was indeed in the uterus, would be if she either stood up straight, or had a bizarre conformation!

As far as the mare still "showing" - remember that mares will remain receptive to the stallion until progesterone levels being secreted from the newly forming CL are adequately elevated to cause resistance, and that is not until about 24-48 hours after ovulation.

Oxytocin use is always a worth-while consideration in older mares.

lol - no, this mare's conformation is pretty normal, sounds like it was just user error on my part. I have inseminated several mares over the years and never had one spill it back out like this. Her cervix was wide open and soft, but I guess I could have not cleared it totally (which is what I am hoping did not happen!). It was definitely the white semen/extender that I put in there that came back out - but not all of it, so maybe there is still hope! Thanks so much for your input - I will post with results in about 16 days...

Ok, so the mare was still in Tuesday, so I inseminated her again. MADE SURE the pipette was past her cervix, and not a drop came out :-) However, the collection was horrible. The stallion handler and the AV handler both thought the stud did not finish the first time, so we waited 5 minutes and collected again. I was pretty sure that he had done his thing the first time though. Also, the first time the AV handler did not tilt the AV down after he was done, so needless to say the collection was in pretty bad shape by the time I looked at it (two collections on top of each other, and I don't think the second collection had one sperm in it). The concentration was not good and 60% were dead. Have you had any experiences where the semen looked pretty pitiful but the mare took? She is out today (showed in yesterday), so assuming she ovulated Tuesday. We have had the worst luck with this mare! I wish she was mine, but she is a client's so that makes it worse!!!

Lose your concern about percentage motility and start worrying about the number of progressively motile sperm that were inseminated. If that number drops below 100 million, then you're more likely to be in trouble. Chances are though, that the number was above that. Take a look at the article on our site entitled "The semen looked bad - or is it?" (follow that link).

On top of that, the insemination from Monday (what there was of it! :-))should still be viable in the uterus until at least Wednesday, and if the mare is "out" today, then the chances are good that she ovulated Tuesday or Wednesday.

Don't start the guessing game though... it will drive you nuts! She either is or isn't pregnant, and you'll know in about 15 days! :-)

I know, I know - I am just a worrier and felt really horrible about the semen. His collections are usually extremely good - not a lot of volume, but highly concentrated and motility is awesome. The one Sunday was awesome if any happened to drain down in there! Thanks for the link, makes me feel a little bit better. I will post with results...

Well, just found out that this mare did not take - ugh! Of course we had several things working against us in this situation - this is an older mare who did not take last year. We tried her in March of this year and I am pretty sure that was a transitional cycle, so it was a bust, then the 2nd try we had all of these problems. Thank goodness we have already gotten one of this client's mares in foal this year because he still has another one to bring us! She was at a 28 today so looks like we will be breeding her soon - seems like she should be futher along in her cycle than this, but that is what the vet said. Oh yeah, and supposed to get sperm count checked tomorrow (if we collect). He is still giving us 25 mL every time, and we have had to collect him 4 days in a row because of high volume of mares.
