Cryptorchidism in cats is a condition in which one or both testicles do not descend properly into the scrotum. Cats with only one descended testicle can still produce offspring, but those with two undescended ones will be sterile. You may be wondering what causes this condition.

Causes

Cryptorchidism is present at birth. This means that the trait can be passed down through family lines. That is why it is a good idea to ensure that cats with the condition never produce offspring, or their offspring may be affected as well. All races can be affected. However, certain breeds such as Persians, Cocker Spaniels, and Chihuahuas are often more affected than other breeds.

Diagnosis

The vet should palpate the scrotum to detect the absence of one or both testicles. However, if you don’t know your cat’s complete medical history, it could be difficult to easily diagnose cryptorchidism in cats. Instead of having two undescended testicles, your cat may have already been neutered.

In these cases, the vet will have two options. You can perform an abdominal ultrasound to look for one or both testicles. It can also measure the level of testosterone in the blood.

Treatment

With cryptorchidism in cats, the undescended testicle is not functional and does not develop properly. However, cats with an undescended testicle are much more likely to develop a certain type of cancer later in life. Therefore, it is best to have your testicle removed. Also, you know that a properly descended testicle allows the cat to produce offspring. It must also be removed because any descendant will carry this trait in all likelihood.
