Q: I can only feel one testicle on my yearling stud colt. Is it possible his other testicle could descend later or could he be a cryptorchid? If he is a cryptorchid, will he still be suitable for breeding? A: If the colt was born with two testicles, chances are that the second one will descend.

Old maiden mares are considered special mares with the possibility of reduced fertility. An old maiden mare is a mare that is older than eight or nine and has never had a foal. However, there are other mares that are in the same category; mares that are bred at the age of two, foal when they are three, and then go into a show career and are not bred again until they are 12 or older behave very similarly. Not all are the same, but they are all at a higher risk of being a problem.
