               QUESTIONS

               In the following multiple choice questions, choose the letter corresponding to the
               one best answer.


                 1.  What cells form the blood–testis barrier?

                       A.  Spermatogonia

                       B.  Spermatocytes

                       C.  Capillary endothelial cells

                       D.  Sertoli cells

                       E.  Interstitial cells (of Leydig)

                 2.  What important role does the blood–testis barrier perform in the male

                      reproductive system?

                       A.  It prevents the passage of testosterone into the seminiferous tubules.

                       B.    It  prevents  an  autoimmune  response  to  sperm  and  induction  of
                            infertility.

                       C.  It separates spermatocytes from Sertoli cells.

                       D.  It separates the interstitial cells from the capillary network.

                       E.    It  forms  tight  junctions  in  the  endothelial  capillaries  near  the

                            seminiferous tubules.

                 3.    Which  hormone  is  essential  for  maintaining  accessory  reproductive
                      organs?

                       A.  Testosterone

                       B.  Androgen-binding protein


                       C.  Inhibin

                       D.  Luteinizing hormone

                       E.  Sertoli cell hormone

                 4.  When the sperm enter the epididymis:

                       A.  they are motile and can fertilize an oocyte.
