I read in one of the answers somewhere in an article on this site that if the mare is a maiden mare and the hymen is still intact to remove before breeding. Question}: What would happen if you did not remove before breeding the mare?
The stallion is most likely going to be able to break it, but in doing so may cause pain to the mare eliciting a kick - in a very delicate and susceptible place!
In rare instances, the stallion may not be able to break the hymen and is therefore unable to penetrate the mare. In the worst case scenario in that situation, the penis may enter the rectum if the stallion keeps trying to breed the mare, with disastrous (for the mare) results.
In an AI situation, incomplete breakage of the hymen may result in deflection upwards of the foal's feet during the foaling process and a recto-vaginal fistula result. Follow that link for more information and absolute graphic confirmation on why you want to completely rupture the hymen...
