I had a colt that had only one testicle. BEWARE. I had him operated on and they only ever found one testicle, not even a 'bud' where the other one should have been. The op invloves going in surgically through the abdomen. My colt was a monorchid apparently but my god a few months later and he was a pain in the a***. A Rig. It's a gamble, if they find nothing it doesn't mean it will not appear later. I sold my colt at a massive loss as you have to treat as a stallion (and yes, he would try to cover).
