There are a few standardbred studs who are crypt. Chocolatier is a good example - although before he entered the breeding shed he had accupuncture to drop the testicle. It worked and he now has full books every year. Accupuncture is a good method to get the testicle to descend - I've seen it work 3 or four times. Yes, it's hereditary but I guess some folks don't care!
