Question

Quizplus · Accepted Answer

The blood-testis barrier is formed by tight junctions between Sertoli cells in the seminiferous tubules, not Leydig cells or the basement membrane. Its primary function is to protect developing sperm from exposure to the immune system, which might recognize sperm as foreign and mount an immune response against them.
