The SCSA has proven its value in stallion breeding soundness exams.  The data below comes from Dr. Bob Kenny formerly at the Kennett Square center, the Univeristy of Pennsylvania.  Note for stallions also, the greater the increase in sperm DNA fragmentation, the lower the fertility index.  In a plenary session at a stallion reproduction session, Dr. Dixon Varner concluded his talk by saying : "If I had three measurements to evaluate stallion breeding soundness, I would choose, sperm concentration, sperm motility and SCSA testing."
