Sid Fernando - Why are intact males such a rare breed?

His like is endangered nowadays. I was jolted by thoughts of this while watching the HRTV broadcast of the Eclipse Award Ceremony from Gulfstream Park on January 18. Wise Dan was the equine star of the evening, a "people's horse" in the same way as Curlin. He, too, is a two-time Horse of the Year and top older horse, plus top turf horse. But Wise Dan is a gelding, and he's by the unheralded Wiseman's Ferry. And he's a turf miler - the weakest division of North American racing.
