Abstract: The present investigation was aimed to study different testicular parameters in indigenous bulls. Twenty four bulls of three age groups namely group A (1.5 to 2 years, n=8), group B (2 to 2.5 years, n=8) and group C (above 2.5 years, n=8) bearing 2, 4 and 6 permanent incisor teeth respectively, were selected. Body weight and scrotal circumference were recorded before slaughter and various testicular parameters were measured after slaughter. The average circumference of left and right testes were 12.75±0.55 cm and 11.82±0.46 cm in the group A,15.37±0.21 cm and 14.90±0.32 cm in the group B and 18.23±9.75 cm and 17.26±9.75 cm in the group C, respectively. The body weight was significantly correlated with testicular circumference of left testis (r=0.99, P
