Glitterman, sire of four millionaires, has been pensioned at Nathan Fox and Richard Kaster's Wafare Farm near Midway, Ky., because of fertility problems. The 20-year-old son of Dewan covered about a dozen mares and none of the ones checked is in foal."Glitterman has been a very fertile stallion throughout his career, but our staff began noticing a change in him toward the end of February, prompting us to have the leading experts (Drs. Phil McCarthy and John Steiner) in the field of stallion fertility collect (samples) and examine him thoroughly," Fox said. "Each of these experts agreed that he was no longer capable of impregnating mares. His libido remains fine, and he is in great health."A world-record-setting sprinter on the racetrack, Glitterman has sired millionaires Balto Star, Glitter Woman, J J'sdream, and Champali among his 26 stakes winners. Balto Star and Glitter Woman were both grade I winners, and Balto Star and Champali were graded winners in 2004. Glitterman has sired 23 stakes-placed runners and has progeny earnings of nearly $28.5 million.Bred by Frank D. Turner and produced from the In Reality mare Moon Glitter, Glitterman set a world record of 1:01 3/5 for 5 1/2 furlongs on turf at Hialeah in 1989 in one of his nine wins from 25 starts. He earned a career total of $473,914.Fox planned to breed Glitterman to 75 mares this year. "He covered 76 last year and got 60 something in foal," he said.Glitterman, who began his stallion career at Lucas Farm near Summerfield, Fla., stood this year for $15,000.
