Sperm smear histology

Description:Tight junctions may temporarily open to permit the passage of spermatogenic cells from the basal into the adluminal compartment. A fold in the nuclear membrane is characteristic for Sertoli cells but not always visible in the LM well Sertoli cells are far less numerous than the spermatogenic cells and are evenly distributed between them. They appear larger than spermatogonia. An nigrosin-eosin stain is commonly used because it is effective, simple and, in addition to allowing sperm to be readily visualized, it is a so-called "live-dead" stain, allowing one to assess membrane integrity at the same time as morphology. Examine using a bright field microscope typically using a X objective lens. The tunica albuginea is covered externally by a serosa.
