The specific syndrome was first noted as possibly being caused 'by a new entity by Dr. Jack Ward in the Bitterroot Valley of Montana after Dr. Ward was unable to relate the observations of necropsied specimens with that of any known published reports.

Testicular Development And Onset Of Puberty In Beef Bulls, Donald D. Lunstra

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Selection and management of young beef bulls have been hampered by a lack of information on reproductive development, growth, and puberty. The use of an increasing number of sire breeds in the beef cattle industry has placed additional emphasis on the importance of defining differences in sexual maturation within and among breeds. We conducted the following studies as part of a program designed to characterize reproductive development and puberty in breeds of beef bulls.
