title: Relationship between testicular transferrin and plasma estradiol-17beta concentrations of dogs with azoospermia and dogs with sertoli cell tumors.
abstract: Testicular Transferrin (Tf) and peripheral plasma estradiol-17beta (E2) concentrations were measured in 3 dogs with azoospermia (AZ dogs), 3 dogs with Sertoli cell tumors (SC dogs), and 5 normal male Beagles. The mean Tf concentrations in the testes of the AZ dogs and the affected testes of the SC dogs, and the plasma E2 concentrations in both these groups of dogs were significantly higher than the values in normal dogs (P<0.05, 0.01 and 0.01, respectively). Therefore, excessive E2 secretion by hyperfunctioning Sertoli cells is thought to have caused the azoospermia in the 3 dogs.
