View Full Version : unilateral cryptorchidism?? Still Fertile??

I have a question. If a dog has a unilateral cryptorchidism/monorchidism ( condition in which only one testis descends ) Does this make the dog sterile? Or are they still able to reproduce with only one testicle? This is a topic of debate among some friends who had this disorder in what was supposed to be a future show prospect, they opted to have him neutered and just be a house pet instead of a show dog....The vet was not very informative as to any details concerning this...so does anyone have a more in depth explanation of this condition and the effects it has on the fertility of a dog. A little off topic..but a couple we know had a baby recently..through natural means...and the dad only had one testicle...wouldn't it be the same for animals?

Yes it would be the same for animals. It really does depend though. It is best that he is neutored though so he is not bred and does not pass on his genes because it is most likely hereditary.

A dog with only one testicle is still fertile, although less so than when both descend. Orchism is genetic and a monorchid (one testicle descended) can produce cryptorchids (neither testicle descended). The main issue with regard to the retained testicle is that they are much more prone to become cancerous. I would definitely have any pup with retained testicles neutered for his own health.
