Hi Jos, Kathy, or anyone else - could use your help.

A friend of mine just had her mare lose yet another pregnancy at 8 months gestation. She is thinking of giving up on this mare or turning her into an ET donor.

This mare has a "grade IIB biopsy with lots of fibrosis" and that is what is being blamed on the pregnancy loss at this stage; however, I was under the impression that this impacts the first trimester more than any other time?? Yes/no?

Mare was cultured/cytologied clean before breeding. Does not currently appear to have an infection to blame for the abortion.

I am wondering:
Should this mare have a DMSO/Betadine flush to clear out the the fibrosis before breeding this coming spring?

Will the DMSO/Betadine flush improve the Biopsy score?

Does a IIB biopsy score impact the mare's ability to carry any pregnancy to term, regardless of how long into it?

Could this mare become a decent ET Donor? Her pedigree and her warmblood approval scores merit her as a possible candidate. Mare gets pregnant quite easily and without too much fuss, perhaps needing a post insemination flush.

Just for anyone else that's reading this question:

Does a IIB biopsy score impact the mare's ability to carry any pregnancy to term, regardless of how long into it?

Yes. A IIB score carries a 10-50% chance of live foal production - so that involves pregnancy loss at any stage of pregnancy.

This mare has a "grade IIB biopsy with lots of fibrosis" and that is what is being blamed on the pregnancy loss at this stage; however, I was under the impression that this impacts the first trimester more than any other time?? Yes/no?

No. Fibrosis impacts pregnancy maintenance when placentation has occurred, which means anytime after about 40 days.

Will the DMSO/Betadine flush improve the Biopsy score?

It may.

Could this mare become a decent ET Donor?

This would probably be the best solution for the mare if they want a foal out of her.
