title: A new light microscopy classification of spermatogenesis in the bull and the boar applicable to tissues processed for electron microscopy.
abstract: A new light microscopy classification of spermatogenesis in the bull and the boar was formulated to be used in conjunction with electron microscopy. It uses information available from all cell types and allows for very small portions of testicular epithelium at any orientation to be evaluated. The classification devised, being simple in outline, allows for the natural overlap of cell types. Furthermore, it emphasises the direct comparability of the morphological events occurring during spermatogenesis in the bull and the boar.
