Study Questions

Cryptorchids come in 3 flavors – high flankers, abdominal cryptorchids and monorchids. Monorchids are very rare.What is the difference between the other two?

Could either high flankers or abdominal crypts be reasonably castrated in the field?

What is the descent path of the testicle (so where might a cryptorchid testicle be found)?

Which testicle descends last (and might be more likely to be abdominal)?

If you are attempting to find the missing testicle on a cryptorchid animal, should you remove the descended one first?

What are the possible consequences of leaving a testicle in the abdomen, particularly if you remove the other?

The Cryptorchid, R-Vets- Note: just because you CAN do a cryptorchid surgery in the field, doesn’t mean you SHOULD in most cases. Your ethical obligation is to provide the best care possible. If referral is possible, that is generally the best care.
