I'm assuming you aren't the breeder? The breeder of the horse can unspay them for the cost of 1 gmt.

Some players will unspay horses for you at cost.

To help prevent that from happening again, you can turn testing off on select horses (or all of them). It can be done on the horses individual page, or at the bottom of the barn page. The only downside is that you will have to turn testing back on if you want to comparison test, but it's a small inconvenience compared to accidentally spying everything.
