Bilateral cryptorchidism in a horse
Keywords: cryptorchid, equine, bilateral
Image size: 1050 x 848px
This is a comparatively rare image because only about 10% of the cases of cryptorchidism in horses are bilateral. About 60% of all cryptorchid testicles are abdominal (not in the inguinal canal). These testicles were very soft and would have been difficult to palpate per rectum. They were removed from the abdomen of a two year old Appaloosa stallion (POA).
Note the wide space between the distal poles of the testicles and the tails of the epididymides. This is an occasional source of mistaken identity during surgery for cryptorchidism, when the tail of the epididymis is thought to be the testicle itself. The ductes deferentes can be seen on either side, medial to the testicles, pointing towards the top of the image
