Question #45278
The Question
A male patient exhibits normal testosterone levels and normal mitotic proliferation of spermatogonia, but a complete destruction of primary spermatocytes and subsequent meiotic lineages due to an autoimmune response. This pathology most likely arises from a structural defect in which of the following?
Options
- A.
Tight junctions between adjacent Sertoli cells
- B.
Gap junctions between Leydig cells and Sertoli cells
- C.
Luteinizing Hormone (LH) receptors on the interstitial cells
- D.
The secretion of Androgen Binding Protein (ABP) into the tubule lumen

Why This Question Is Tricky
Common Mistakes
Conceptual Pivot: Students often memorize Sertoli cells merely as 'nurse cells' providing nutrition, overlooking their critical structural role in forming the Blood-Testis Barrier.
The trap also tests the integration of Human Reproduction with Immunology—specifically, the concept that post-pubertal meiotic antigens are immunogenic because they were absent during the fetal establishment of 'self' tolerance.
