Judged by their ultrastructural features, these cells clearly take the form of apoptosis and finally are subjected to phagocytosis by neighboring Sertoli cells; only a few germ cells of a presumably incipient, partly variant degenerative morphology cannot, at present, be assigned to the apoptotic mode of cellular death. Degenerating prespermatogonia occur between the 14th dpc and 3rd dpp and again, after an interval in which no such cells are found, from the 9th dpp onwards. This pattern reveals a striking parallelism to the phases of proliferation of these cells, viz., the appearance of M- and T2-prespermatogonia. Both this obvious temporal association of proliferation and degeneration and the classification of prespermatogonial death as apoptosis suggest some developmental significance of the degenerative phenomena investigated.
