Abstract

1. The left and right testis weights from 378 males in 7 experiments were recorded. 2. The relationship between the right and left testis weights was similar in males of different ages, strains and body weights. 3. The left as a proportion of total testes weight was approximately normally distributed about a mean of 0.515. 4. The left testis was greater than the right testis weight in 0.67 of males. 5. The linear regression of the natural logarithm of the right on that of the left testis weights was -0.04 + 0.99X (r2 = 0.98) and it was concluded that, in general, the left and right testes were of similar weight. 6. Three cases of triorchidism (two left testes) occurred, suggesting that this may not be a rare condition in the domestic fowl
