After meiosis in the male primary spermatocyte, the resultant secondary spermatocytes are genetically different than the body's somatic cells. The immune system is inclined to attack this 'foreign' cell. Which of the following contributes to the prevention of auto-immune responses to one's own spermatocytes?

a. The desmosomes of sustentacular cells
b. The blood-testis-barrier
c. The acrosome of the sperm cell
d. All of these choices are correct.
e. None of these choices is correct.

Option B.

The blood testis barrier.

Explanation:

The blood testis barrier is the physical barrier between the blood vessels and seminiferous tubules of human testis. It prevent sperm antigen from contracting systemic and lymph circulations preventing immune response.

After meiosis, the resultant secondary spermatocytes are genetically different from the somatic cells. The blood barrier testis serve as a physical barrier and prevent sperm antigen from contracting systemic and lymph circulation thereby preventing immune response.
