A 2-year-old 454.5-kg (1,000-lb) Saddlebred stallion was admitted to the University of Illinois Veterinary Teaching Hospital for castration.

Surgery via an inguinal approach did not enable the veterinarian to locate the testis. Therefore, the veterinarian did not remove the contralateral right testis, which was located in the scrotum, and the stallion was referred to our facility for evaluation and subsequent removal of both testes.

Results of physical examination and initial hematologic analysis of the stallion conducted
