Why should my cryptorchid pet be neutered?
Cryptorchidism is when one or both testicles fail to descend into the
scrotum. This condition is a fairly common problem; seen in dogs, cats
and other animals. This is a well-documented genetic trait -- animals
with this condition should not be bred. Find out why in this FAQ.
Cryptorchidism is when one or both testicles fail to descend into the scrotum.
People often wonder why animals that are cryptorchid need to be
neutered. The reason is two-fold. Animals that are cryptorchid may still be fertile, especially if
unilaterally
(one-sided) cryptorchid. Cryptorchidism is a known heritable trait.
This condition is more common in some breeds, but seen in all breeds and
is passed on from father to (male) offspring.
In addition to the heritability aspect, the testicle (or testicles) that
remain in the abdomen are more prone to cancer or torsion (twisting and
cutting off blood supply).
I remember a case of a geriatric
Irish Setter that had been neutered as a pup. Apparently, only the
testicle in the scrotum had been removed during surgery. This dog was
presented for difficulty defecating and urinating, with a large
abdominal mass. A very large (12" long) testicle was taking over the
abdomen! Thankfully, surgery went well, and he could live out his senior
years comfortably.
When should my dog be neutered?
Opinions will vary, but if your dog or cat is still cryptorchid (one or
both testicles) by 6 months of age, it is highly unlikely that the
testicle(s) will ever drop, and the animal should be neutered to prevent
testicular tumor formation and passing on this genetic trait to future
generations. If the testicle is not readily palpable in the inguinal
canal (groin area), abdominal exploration is necessary to find the
retained testicle.
While many animals are neutered at young ages, it is my personal
preference to wait until 6 months of age to handle the general
anesthesia. Again, opinions about maturity vary as do anesthetic
protocols used by your vet, so please consult with your veterinarian as
to the best plan of action for your dog.
