Three monorchid colts were admitted for castration as cryptorchids. Two colts each had one normal descended testis, and the third colt had a small testis in the abdomen. Monorchidism was diagnosed at surgery by locating an incomplete epididymis without a testis. After the incomplete epididymis and other testis were removed, the absence of testicular tissue was confirmed by results of a human chorionic gonadotropin response test.
三头单睾雄驹因隐睾症入院接受去势手术。其中两头雄驹各有一个正常下降至阴囊的睾丸，第三头雄驹的腹部有一个小睾丸。手术中通过定位没有睾丸的不完整附睾诊断为单睾症。切除不完整附睾和另一个睾丸后，通过人绒毛膜促性腺激素反应试验结果证实无睾丸组织。
