Monorchidism in three colts.
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.
