Question

Quizplus · Accepted Answer

The blood-testis barrier prevents immune responses against the surface antigens of spermatogenic cells, which can be recognized as foreign by the body's immune system. This barrier is formed by tight junctions between Sertoli cells, which regulates the exchange of substances between the blood and developing sperm.
