(A) Photomicrograph showing the cross section of H&E staining of the testes of a representative mouse from groups Control, C-Se, Abx and Abx + Se. The basement membrane (bm), spermatogonia cells (sg), spermatocytes (sc), spermatids (st) and spermatozoids (sz) are indicated by arrows. (400 × magnification). (B) Bar plots showing the average counts for each germ cell type in the seminiferous tubule; the scheme illustrates the process of generation of the different types of germ cells during spermatogenesis.
