Cryptorchidism
Hereditary
A congenital condition in which one or both testicles fail to descend into the scrotum, remaining in the abdomen or inguinal canal. It is inherited with a complex, likely sex-limited pattern and is more common in small and toy breeds. Retained testicles carry an increased risk of neoplasia and torsion.
