I've never heard of one and yeah that could be problematic! There may be some but I'm sure most are geldings if only because some of those horses can get quite amorous even to male horses!! Give them a mare, and OMG!

We had one but she was spayed (had cysts on both ovaries) and even spayed we knew which horses could not be ponied off of her. There were a few colts that just being near a female was enough to make them stupid.
I ponied on the track for years and never saw a mare being used. I suppose it would be possible, but not likely. Now, if you are going to pony a filly or something at home, why not? But on the track? Never happen.
We have a couple few filly/mares being used. Seems like no issue for the most part.
My favorite little filly is a 3 year old roan. She is small and awesome. I wish she hadn't started ponying as young as she has, but she works. I have never seen her have an issue with a situation with a horse she is ponying in the am or the pm.
I kind of have a pony crush on her.
It is much more common to use geldings.

I have 2 different friends that used mares to pony. Stella and Choco both pony regularly, but most are geldings. I've experienced stallions trying to mount my gelding while ponying. Not much fun, I'd hate to try taking one with a mare.....
A good friend of mine ponied with her mare for years! Big gorgeous Appy. She was great, but I would venture to say that she may have switched often if she had a stud. On the other hand, I ponied with a stud that had even been bred. He was an exception to the rule though, such a great horse. The only time he got rank with me was when we took another rank stud to post, then I only had to keep more outside rein on him to keep his mouth off the racehorse! It bothered him if another horse was arrogant!
