Where is the blood testis barrier located?

Keeping this in consideration, why is there a blood testis barrier?
The blood-testis barrier created by tight junctions between Sertoli cells normally isolates sperm from immune recognition. When the barrier is disrupted and sperm are exposed to blood, however, an antigenic response is elicited.
Secondly, what cells make up the blood testis barrier? The name "blood-testis barrier" is misleading in that it is not a blood-organ barrier in a strict sense, but is formed between Sertoli cells of the seminiferous tubule and as such isolates the further developed stages of germ cells from the blood. A more correct term is the "Sertoli cell barrier" (SCB).
Also know, what can cross the blood testis barrier?
By preventing the passage of most molecules between adjacent Sertoli cells, the blood–testis barrier allows the creation of a highly specialized biochemical environment essential for meiotic development (Cheng and Mruk 2002; Griswold 1988). It also blocks access by lymphocytes, complement, and antibody (Ben et al.
Why do they require a blood testis barrier to prevent antibody formation?
The Blood-Testis Barrier Creates an Immunological Barrier. This is necessary to avoid the production of anti-sperm antibodies and autoimmune disease, which leads to male infertility (Francavilla et al., 2007).
