The relationship of scrotal circumference to histological testicular parameters and sperm reserves.J S Afr Vet Assoc 1993; 64(3):126-7JS
Bonsmara bulls (n = 10) were castrated at 410 d of age. Their scrotal circumference varied between 31.0 and 42.0 cm (mean: 36.0; SD: 1.7). Bulls were divided into above average (> 36 cm) and below average (< 36 cm) groups. Significant correlations were reported for scrotal circumference with seminiferous tubules diameter (r = 0.84), percentage vacuolisation (r = -0.74) and epididymal sperm reserves (r = 0.79). A significant linear relationship (Y = 3.9 X = 105.3) was reported between scrotal circumference and epididymal sperm reserves.
