Should Greater Good win the May 7 Kentucky Derby (gr. I), it would make the second time in the past three years the winner cannot stand at stud.

Funny Cide, who won the 2003 Derby, is a gelding. Greater Good is listed as a colt but because neither of his testicles has descended, he has no value as a stallion prospect.

For the record, Greater Good, by the Phone Trick stallion Intidab out of the General Assembly mare Gather The Clan, is known as a bilateral cryptorchid. There are many unilateral cryptorchids, known in the industry as a ridgling, meaning one undescended testicle. However, a male Thoroughbred with both testicles undescended is rare.

“In my career, and I’ve been in Ocala (Florida) 20 years, I’ve only seen 15-20, and that covers all breeds of horses,” surgeon John Peloso, DVM, Dipl. ACVS, said. A partner in the Equine Medical Center of Ocala, Peloso does the veterinary work for Becky Thomas, who broke and readied Greater Good for the races
