A 25-month-old castrated horse was admitted for evaluation of stallion-like behavior. Twelve months earlier, bilateral cryptorchidism had been diagnosed, and the horse underwent a laparoscopic castration. At that time, the left testis was removed from the abdominal cavity, but the right testis, which was located in the inguinal ring, was left in place to undergo avascular necrosis after laparoscopic cauterization and transection of the testicular vasculature. On physical examination, an apparently clinically normal right testis was palpated within the scrotum. Administration of human chorionic gonadotropin resulted in an increase in testosterone concentration, which was consistent with the presence of viable testicular tissue. Surgery was performed to remove the testis.
一匹25个月大的去势公马因种马样行为接受评估。12个月前，该马被诊断为双侧隐睾症，并接受了腹腔镜去势手术。当时，左侧睾丸从腹腔中取出，但位于腹股沟环的右侧睾丸留在原位，在腹腔镜烧灼和切断睾丸血管后发生无血管坏死。体格检查时，在阴囊内可触及一个外观临床正常的右侧睾丸。注射人绒毛膜促性腺激素导致睾酮浓度升高，这与存在有活力的睾丸组织一致。遂进行手术切除该睾丸。
