    Human blood testis barrier
    a) Tight junction between Sertoli cells
    b) Absence of germ cells causes immune
    reaction
    c) Formed before spermatogenesis
    d)

    Answer: Tight junction between Sertoli cells

    Explanation:
    Tight junction between adjacent Sertoli cells
    near the basal lamina form a blood-testis
    barrier.
    Blood-testis barrier prevents many large
    molecules from passing from the Interstial
    tissue and the part of tubule near basal lamina
    (Basal compartment) to the region near tubular
    lumen (Ad-luminal compartment) and the
    lumen.
