The adult chicken testes were two bean - shaped , large and soft , the left testis is usually higher in position and larger in size than the right one .

The testis is active during cold weather with the mean diameter of the seminiferous tubules being 126^m in the chicken .

it is less active during the hot season with the mean diameter of the seminiferous tubules being 135^m in the chicken.
