VIABILITY OF AN INGUINAL TESTIS AFTER LAPAROSCOPIC CAUTERIZATION AND TRANSECTION OF ITS BLOOD-SUPPLY

A 25-month-old castrated horse was admitted for evaluation of stallion -like behavior. Twelve months earlier, bilateral cryptorchidism had be en diagnosed, and the horse underwent a laparoscopic castration. At th at time, the left testis was removed from the abdominal cavity, but th e right testis, which was located in the inguinal ring, was left in pl ace to undergo avascular necrosis after laparoscopic cauterization and transection of the testicular vasculature. On physical examination, a n apparently clinically normal right testis was palpated within the sc rotum. Administration of human chorionic gonadotropin resulted in an i ncrease in testosterone concentration, which was consistent with the p resence of viable testicular tissue. Surgery was performed to remove t he testis.
