On the one hand, the reason for this appearance lies in the fact that the daughter cells, generated by each meiotic step, remain bound together by thin cytoplasmic bridges. Thus with each meiotic step the following generation is twice as large, until the cells have formed a relatively complex network. The result is that cells of the same development stages are seen there in groups. On the other hand, in addition, other spermatogenesis generations are wound around each other in spirals along the seminiferous tubule. This is why one meets with groupings of various generations in a tubule cross-section. Thus, it is highly improbable that all of the development stages will be seen in a single section at the same time.
