Seminiferous tubules
Spermatogonia and early primary spermatocytes are located in the basal compartment created by the blood-testis barrier. Older primary spermatocytes, secondary spermatocytes and spermatids, all located in the adluminal compartment, are provided with a specialized environment of high testosterone levels and protection from an autoimmune attack. 600x
