Cryptorchidism
Cryptorchidism is a condition where one or both testicles fail to descend into the scrotum. It is a common defect in dogs and has a genetic basis.
Key Facts
- Testicles should be palpable by 8 weeks in puppies, 8-16 weeks in kittens
- Unilateral (one side, usually right) is more common than bilateral
- Bilaterally cryptorchid animals are usually sterile but still exhibit male behaviors
- Predisposed breeds: Yorkshire Terrier, Pomeranian, Poodle, Siberian Husky, German Shepherd
- Retained testicles are prone to testicular torsion and testicular cancer
- Both testicles must be removed surgically (even if one is normal) to prevent passing on the gene
- Surgery is more complex than routine neutering due to difficulty locating retained testicle
- Abdominal testicles are typically not palpable; testosterone assay distinguishes from castrated males
- In cats, most common in Persians; penile barbs indicate cryptorchidism vs castration
- Species: dogs and cats
