Sertoli Cells
Supporting cells of the tubules of the testis.
Blood-Testis Barrier
A physical barrier formed by Sertoli cells in the walls of seminiferous tubules in the testes, crucial for protecting germ cells from harmful substances and autoimmune attacks.

Final Answer :
E
Explanation :
Sertoli cells do not help move sperm into the blood. Instead, they support and nourish developing sperm cells, form the blood-testis barrier, phagocytize discarded sperm cytoplasm, and are joined by tight junctions. Sperm are eventually released into the seminiferous tubule lumen, not the blood.
