Testicular tumors are considered one of the most common tumors in older intact male dogs. The overall incidence in dogs is not very high because most dogs are castrated (neutered) at a young age. The three most common types of testicular tumors are Sertoli cell tumors, interstitial (Leydig) cell tumors and seminomas.
Causes– Dogs with retained or undescended (testes that do not descend into the scrotum) testes have a propensity for Sertoli cell tumors and seminomas. Studies have indicated that cryptorchidism (absence of one or both testes from the scrotum) is one of the most important contributing factors to testicular cancer.
There does not appear to be any breed predilection for this tumor. The current cause of testicular tumors is unknown. Dogs that have one or both testicles that .

As with most cancers, the cause of testicular tumors is unknown. However, since some of these tumors have been correlated with the presence of undescended .
Seminomas are fairly rare neoplastic testicular tumors that develop on the testes of intact male dogs. They can be benign or malignant, and they are made up of .
The detection rate of testicular tumors was 16.8% (80/476) in male canine. 52 (54.2%) tumors developed from cryptorchid testes in 45 dogs (56.3%), and 44 .
